Description

Sewage treatment pipeline and sewage treatment system

Technical Field

The invention relates to the field of sewage treatment equipment, in particular to a sewage treatment pipeline and a sewage treatment system.

Background

The sewage is generally treated by catalysis through a catalyst. The method mainly utilizes high-activity hydroxyl free radicals (mainly-OH) to attack and react with macromolecular organic matters, thereby destroying the molecular structure of the organic matters to achieve the aim of removing the organic matters by oxidation and realizing efficient oxidation treatment. The advanced oxidation technology for treating the organic wastewater which is difficult to degrade is the development trend of wastewater treatment in the future, but the main problems of hindering the application and popularization of the organic wastewater at the present stage are as follows: the running cost of the advanced oxidation technology is relatively high, which is mainly reflected in the following aspects: the contact time of the catalyst and the sewage is not long enough, the contact area is limited, and if the contact time is long, the water flow speed needs to be correspondingly reduced; secondly, the following steps: when the catalyst needs to be replaced, the pipeline where the catalyst is located needs to be replaced by cutting off water, so that the shutdown operation is required, and the shutdown time is increased.

Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 10: the embodiment discloses a sewage treatment pipeline: contain the treatment circuit of multiunit series connection, every group treatment circuit contains two vertical pipelines 1 that the upper end switched on, be equipped with the fixed subassembly of catalyst in the vertical pipeline 1, the fixed subassembly of catalyst includes the center tube 8 with the coaxial setting of vertical pipeline 1, center tube 8 is equipped with a plurality of sleeves 801 that set up perpendicularly with center tube 8, adjacent sleeve 801 sets up in turn perpendicularly, be equipped with catalyst installed part 83 in the sleeve 801, catalyst installed part 83's both ends all are equipped with detachable catalyst and place chamber 84, the catalyst is placed chamber 84 and is used for holding the catalyst. The catalyst-accommodating chamber 84 has a generally cylindrical shape, and the side thereof is generally provided with a mesh so that sewage can enter the inside thereof.

The center of the catalyst mounting member 83 is connected with a linkage assembly arranged inside the center pipe 8; the upper end of the central tube 8 extends to the upper part of the vertical pipeline 1 (extending out of the vertical pipeline 1) and is driven by the oscillating device 7. The swinging means 7 drives the center pipe 8 to rotate centering on its own axis, and the rotation of the center pipe 8 can drive the catalyst mount 83 to rotate within the sleeve 801 by the linkage assembly.

Specifically, the method comprises the following steps: the linkage assembly comprises a pull rod 51 and a driving sleeve 85 which are arranged inside the central tube 8 and are alternately connected, a rack 851 is arranged inside the driving sleeve 85, a gear 831 is arranged at the center of the catalyst mounting piece 83, the gear 831 is meshed with the rack 851, a second swing arm 82 is arranged at the end part of the pull rod 51, and the second swing arm 82 is connected to the chute 751. The swing device 7 comprises a first swing arm 74 arranged on the central tube 8, the first swing arm 74 is hinged to one end of a connecting rod 72, the other end of the connecting rod 72 is hinged to a non-circle center of a turntable 73, and the turntable 73 is connected to a power output end of the motor 71. When the motor 71 rotates, the turntable 73 is driven to rotate, and then the swing arm 74 is driven by the connecting rod 72 to drive the central tube 8 to do reciprocating rotation movement with a certain amplitude. When the central tube 8 makes a certain amplitude of circular reciprocating motion, the inclined groove 751 acts on the second swing arm 82 to realize the up-and-down reciprocating motion of the pull rod 51 relative to the central tube 8. The central tube 8 is typically a square tube and the drive sleeve 85 is axially slidable within it but does not rotate relative to the central tube 8.

With reference to fig. 5 and 6: the catalyst mounting member 83 of this embodiment includes two separation blade one 86 that length is less than the catalyst and places the chamber 84, two separation blade two 87 that length is greater than the catalyst and places the chamber 84, and separation blade one 86, separation blade two 87 set up in turn, and the tip of separation blade two 87 is equipped with the buckle 871 that is used for the fixed catalyst to place the chamber 84 tip. The purpose of the relatively short length of the first stop tab 86 is to facilitate replacement and installation of the catalyst holding chamber 84 by maintenance personnel.

In this embodiment, the upper ends of the two vertical pipelines 1 of each group of processing circuits are communicated with each other through the upper elbow 5, the lower end of the upper elbow 5 is provided with the inner conical section 52, the upper ends of the vertical pipelines 1 are connected with the inner conical section 52 through the outer conical end 15, the cross beam 16 is further arranged between the adjacent vertical pipelines 1, and the upper elbow 5 is connected with the cross beam 16 through the vertically arranged pull rod 51. This has the advantage that the upper tube bend 5 is easily removed and the central tube 8 is rotatably connected to the upper tube bend 5 and passes through the upper tube bend 5. That is to say, the whole catalyst fixing component is fixed by the central tube 8, and the fixing mode can adopt any one of the prior art, for example, the central tube mounting sleeve 53 is arranged on the upper bent tube 5, and a certain support frame is arranged at the lower end of the central tube mounting sleeve 53, because the whole catalyst fixing component is vertically arranged and hardly bears the force in the horizontal direction, the lower part of the central tube 8 is preferably not fixedly connected with the vertical pipeline 1, but only depends on the upper bent tube 5 to fix the catalyst fixing component, so that the greatest benefit is that the whole catalyst fixing component can be conveniently pulled out from the vertical pipeline 1, and the catalyst placing cavity 84 can be conveniently detached. And the upper bent pipe 5 is provided with an arc bracket 75, and the aforementioned inclined groove 751 is provided to the arc bracket 75.

Furthermore, sealing means, such as prior art seals, are preferably provided between the outer tapered end 15 and the inner tapered section 52; in order to ensure the right positioning of the external conical end 15 and the internal conical section 52, the transverse beam 16 preferably guides the pull rod 51 vertically to avoid the upper bend 5 from tilting relative to the vertical pipe 1. The bottom of the pull rod 51 can be provided with threads which are connected with nuts, and the upper bent pipe 5 is pulled to be arranged above the vertical pipeline 1 through the matching of the threads and the nuts.

Adopt above-mentioned catalyst fixed subassembly can realize the quick replacement of catalyst, but the catalyst is when changing, need demolish upper bend 5 and whole catalyst fixed subassembly from vertical pipeline 1, because the mode of establishing ties connects between each treatment circuit, consequently when changing the catalyst of a certain treatment circuit, whole sewage treatment pipeline just need cut off water. In order to solve this problem, the present embodiment further adopts the following measures:

referring to fig. 1 and 9: the lower ends of all the vertical pipelines 1 are communicated with the horizontal pipelines 2, the two vertical pipelines 1 of each group of processing loops are respectively connected with the horizontal pipelines 2 through a first valve 11 and a second valve 12, and the horizontal pipelines 2 are also provided with intermediate valves 21 positioned between the adjacent groups of processing loops.

Further, in order to operate the three valves (the first valve 11, the second valve 12, and the intermediate valve 21) rapidly and simultaneously, a valve synchronous driving system is further designed in this embodiment, specifically: the operation ends of the first valve 11, the second valve 12 and the middle valve 21 are respectively provided with a driven chain wheel 41, all the driven chain wheels 41 are connected through chains 42 (connected end to end), the chains 42 are connected with the driving chain wheel 4, the driven chain wheel 41 of the first valve 11, the driven chain wheel 41 of the second valve 12 and the driving chain wheel 4 are arranged inside the chains 42, and the driven chain wheel 41 of the middle valve 21 is arranged outside the chains 42; the drive sprocket 4 is connected to a hand-operated device, such as a rocker 43. Wherein, the specification of three valves is preferably the same, and the specification of four chain wheels is also preferably the same.

That is to say: when the positions of the valve cores of the first valve 11 and the second valve 12 are the same and the position of the valve core of the middle valve 21 is opposite to the positions of the valve cores of the two valves, the linkage of the three valves can be realized through the driving chain wheel 4, and then the synchronous control of the three valves is realized. For example: when the first valve 11 and the second valve 12 are both in the closed state, the treatment loop in which the first valve 11 and the second valve 12 are located stops treating sewage, and the intermediate valve 21 is in the open state, so that the whole pipeline is kept smooth. On the contrary, when the first valve 11 and the second valve 12 are both in the open state, the intermediate valve 21 is in the closed state, and the treatment loop normally treats sewage.

Wherein, all vertical pipelines 1 all can be supported by frame 6, and above-mentioned each valve, horizontal pipeline 2 also can be fixed through support 6, and the upper end of frame 6 is equipped with motor mounting bracket 61, fixes motor 71 through motor mounting bracket 61.

Referring to fig. 7, 8 and 10: because catalytic reaction receives the influence of ambient temperature, in order to promote reaction efficiency, preferably heat the sewage of handling, the outside of vertical pipeline 1 of this embodiment still is equipped with outer heating element, outer heating element is including cup jointing in the outside heat preservation pipe 3 of vertical pipeline 1, be equipped with alternate arrangement's heat exchange piece one 33 between the outer heat preservation pipe 3, heat exchange piece two 34, the lower extreme of heat exchange piece one 33 is equipped with breach one 331, the upper end of heat exchange piece two 34 is equipped with breach two 341, the both ends of outer heat preservation pipe 3 are equipped with inlet one 31, inlet two 32 respectively, inlet one 31, inlet two 32 switch on in the heat source (like the conduction oil). Fig. 10 is an expanded schematic view of the external heating assembly, in which arrows indicate the flow direction of the heat-conducting oil in the heating circuit between the vertical pipeline 1 and the external heat-insulating pipe 3, wherein the heat-exchanging fins can form the heating circuit into a plurality of heating pipelines reciprocating on the outer surface of the vertical pipeline 1, and can increase the direct contact area with the heat-conducting oil.

Wherein, the processing loop is also provided with an ultrasonic generating device 13, the ultrasonic generating device 13 is provided with a U-shaped pipe 14 capable of transmitting ultrasonic vibration, and the U-shaped pipe 14 is arranged inside the vertical pipeline 1. The function of the ultrasonic generator 13 is to further increase the contact between the sewage and the catalyst.

The embodiment also discloses a sewage treatment system, which comprises the sewage treatment pipeline.

In operation, the sewage after physical treatment (usually including grating and filter) enters the horizontal pipeline 2, and when all treatment circuits are working normally, all the intermediate valves 12 are in a closed state, and all the first valves 11 and the second valves 12 are in an open state. Thus, the sewage enters the next treatment link through all the treatment loops in sequence. In the process, the motor 71 drives the turntable 73 to rotate, the central tube 8 is driven to rotate back and forth through the connecting rod 72 and the swing arm one 74, and the rotating range of the central tube 8 is usually not more than 90 degrees. The rotation of the central tube 8 drives all the catalyst containing cavities 84 to swing back and forth with the center of the vertical pipeline 1 as an axis. On the other hand, the rotation of the central tube 8 makes the swing arm two 82 swing with the same amplitude (the central rod does not rotate relative to the central tube 8, but only moves axially relative to the central tube 8), and the inclined groove 751 acts on the swing arm two 82 to drive the gear 831 by the rack 851, so that the catalyst placing cavity 84 rotates back and forth. This has the advantage that the catalyst containing chamber 84 can be used for stirring and fully contacting the sewage; further, the catalyst containing chamber 84 is rotated by itself, and the circumferential surfaces of the catalyst containing chamber 84 can be uniformly contacted with the waste water, so that the catalyst in the entire catalyst containing chamber 8 can be used uniformly.

When the catalyst of a certain processing loop needs to be replaced, the processing loop is disconnected by controlling the closing of the corresponding valve, and the processing loop is subjected to short circuit through the horizontal pipeline 2 at the corresponding position without influencing the conduction of the whole pipeline. Fig. 9 shows a state where the leftmost treatment circuit is short-circuited in the drawing, and the arrows in the drawing indicate the flow direction of the wastewater.

When the catalyst of one processing loop is replaced, the rocker 43 of the processing loop is rotated to enable the first valve 11 and the second valve 12 to be in a closed state, and the intermediate valve 21 is synchronously in an open state. The tie rods 51 and the connecting rods 72 of the process loop are then released and the entire upper elbow 5 and the corresponding catalyst holding assembly are lifted upwards by the lifting device. The entire catalyst placing chamber 84 can be removed from the catalyst mounting member 83 by releasing the second flap 84. Then the catalyst placing cavity 84 filled with new catalyst is placed on the catalyst mounting member 83, when all the catalyst mounting members 83 are replaced, the catalyst fixing component is reinserted into the interior of the vertical pipeline 1 and fastened by the pull rod 51, the driving chain wheel 4 is rotated, the two vertical pipelines 1 are switched to the whole treatment pipeline again, and the sewage treated by the embodiment further enters the next treatment step, such as biochemical treatment.

Compared with the prior art, the embodiment has the following advantages:

firstly, the method comprises the following steps: the vertical pipeline 1 of this embodiment is provided with a plurality of catalyst placing cavities 84 arranged alternately in turn, and these catalyst placing cavities 84 can rotate around the axis of the vertical pipeline 1, and can also rotate, so that the contact effect of the catalyst and the sewage is improved. Furthermore, the catalyst placing chamber 84 itself may rotate, so that each side of the catalyst placing chamber 84 may uniformly contact the sewage in a single flow direction, and the catalyst in the single catalyst placing chamber 84 may be more uniformly used.

Secondly, the method comprises the following steps: when the catalyst of a certain treatment loop needs to be replaced, the treatment loop can be disconnected relative to the whole treatment pipeline through the valve synchronous driving system, and the normal work of other treatment loops is ensured, so that the catalyst in a single treatment loop can be replaced successively on the premise of ensuring the continuous treatment of sewage.

Thirdly, the method comprises the following steps: the valve synchronous driving system, the connection mode between the upper bent pipe 5 and the vertical pipeline 1 and the connection mode between the catalyst placing cavity 84 and the catalyst mounting piece 83 can both improve the replacement speed of the catalyst to the maximum extent, and reduce the influence of the catalyst replacement on sewage treatment.

Fourthly: the contact effect of sewage and catalyst can be further promoted to outer heating element, supersound generating device 13, promotes reaction rate.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
