Description
Technical field
The utility model provides a kind of pressure swing adsorption decarbonization pressure release retracting device, belongs to the inorganic chemical industry apparatus field.
Background technology
The pressure swing adsorption decarbonization technology is according to adsorbent adsorbate have been depressed different adsorbances at the difference branch, and under certain pressure to the characteristic of the selective absorption of each component of separated admixture of gas, impurity composition in the unstripped gas is removed in pressurization, decompression removes these impurity and makes adsorbent obtain regeneration, many absorption, each adsorbent bed pressure that cyclical variations are made up, reach the purpose of continuous separating gas mixture, PSA pressure swing adsorption decarbonization system forms vavuum pump by PLC, computer, adsorption tower, valve station, sequencing valve, oil station.Existing pressure swing adsorption decarbonization is divided into 2 sections absorption, and promptly slightly the section of taking off is under 0.65MPa (table), and absorption is with CO
2Reduce to about 10%, the essence section of taking off is adsorbed under the 1.5MPa situation, makes purified gas CO
2Content is reduced to below 20%.
Thick separation of flow journey is all fallen, contraryly puts, is vacuumized, four all rises the absorption of pressurization back and finish a circulation for absorption, four.
Smart separation of flow journey is the same.
These technology existing problems: 1, slightly take off the inlet superpressure, make gas flow rate too fast, aggravation gas brings hidden danger also for the safe operation of equipment to the erosive wear of adsorbent.
2, PLC sequencing valve etc. is fragile from control, and decrement is produced when light, and system shutdown maintenance when serious causes the unstripped gas waste simultaneously.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: provide a kind of can the reduction slightly to take off device portal pressure, avoid the pressure swing adsorption decarbonization pressure release retracting device of potential safety hazard.
The technical scheme that its technical problem that solves the utility model adopts is: pressure swing adsorption decarbonization pressure release retracting device, comprise the escape pipe of conversion gas device and slightly take off device, escape pipe connects the air inlet pipe of slightly taking off device, it is characterized in that: escape pipe is provided with the blow-down pipe of connection, blow-down pipe is provided with relief valve, escape pipe is provided with pressure sensor, and the output of pressure sensor connects the control end of relief valve.
Pressure sensor detects the just interior pressure of gas device escape pipe in real time, in case the system of transfiniting is then opened relief valve emptying pressure release.
As prioritization scheme, described air inlet pipe of slightly taking off device is provided with atmospheric valve, and the control end of atmospheric valve connects pressure sensor.
As prioritization scheme, described atmospheric valve is connected pressure sensor respectively with the control end of relief valve, and atmospheric valve and relief valve are linkage structure.The linkage structure of atmospheric valve and relief valve is meant pressure sensor control atmospheric valve and relief valve, and atmospheric valve and relief valve move together, and folding together perhaps one is opened one and closed simultaneously, to satisfy the decarbonization process requirement.
As prioritization scheme, described blow-down pipe end is provided with the unstripped gas retracting device.
The beneficial effect that the utility model pressure swing adsorption decarbonization pressure release retracting device is had is: by blow-down pipe is set; and the relief valve of the sensor control that is stressed is set on blow-down pipe; make can be quickly and easily regulating system pressure timely and effectively; production safety is reliable; solved the system overpressure problem; save power consumption; protected the decarburization adsorbent; prolong the service life of adsorbent. at the blow-down pipe end unstripped gas retracting device can be set; reclaim unstripped gas and increase production the carbon ammonium on the one hand, reclaim hydrogen and nitrogen gas on the other hand and continue to produce synthetic ammonia.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Wherein: 1, blow-down pipe 2, relief valve 3, atmospheric valve 4, slightly take off device 5, escape pipe 6, pressure sensor.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
The escape pipe 5 of conversion gas device as shown in Figure 1, connects the air inlet pipe of slightly taking off device 4.Escape pipe 5 is provided with the blow-down pipe 1 of connection, and blow-down pipe 1 is provided with relief valve 2, and escape pipe 5 is provided with pressure sensor 6.The air inlet pipe of slightly taking off device 4 is provided with atmospheric valve 3.The output of pressure sensor 6 connects the control end of relief valve 2 and the control end of atmospheric valve 3.Atmospheric valve 3 is connected pressure sensor 6 respectively with the control end of relief valve 2, and atmospheric valve 3 is a linkage structure with relief valve 2.
Blow-down pipe 1 end is provided with the unstripped gas retracting device.
Mentioned conversion gas device in the utility model, slightly take off device 4 and unstripped gas retracting device, and the circuit of pressure sensor 6 connects, be common prior art, the technical staff is grasped by the industry.
