Description

A kind of cyclone separator

Technical field

The utility model belongs to field of mechanical technique, is related to a kind of cyclone separator.

Background technology

Whirlwind separator as a kind of important separation equipment, can solve dust-laden in pipe gas transmission body, containing mist to conveying and Using the influence of work, extensive profit is obtained in fields such as natural gas, oil, chemical industry, coal-fired power plant and environmental protection With.

It isolates solid, liquid phase impurity and trickle using principles such as gravitational settling, centrifugal sedimentation, cyclonic separations from air-flow Grit.After the gas of entrained solid particles and drop enters cyclone by tangential direction, gas is set at a high speed to be rotated along wall, Downward screw is done to device bottom by spiral routes, the lower rotational gas flow of outer layer is formed, reaches that reflexed is upwards behind bottom, as interior Rotational gas flow on layer, after discharged from the exhaust outlet of separator, into feed-line.

, in high speed of the gas more than 30 meter per seconds, there is separation due to columnar separation chamber in conventional cyclone separator Solid particle taken away again by the upper rotational gas flow of internal layer so that the purification effect of separation is bad.To solve the problem, generally do Method is to carry out multistage cyclone separator, and this secondary or multi-stage separation so causes the cyclone separator purity of one-level more Lowly, and secondary cyclone separator admission pressure diminishes, efficiency step-down.

Utility model content

The utility model is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of cyclone separator, to be solved Technical problem is how to improve purification effect and efficiency.

The utility model is realized by following technical proposal：

A kind of cyclone separator, including cylinder and the bullet being arranged on below cylinder, in cylinder upper end sidepiece Provided with blast pipe, discharge pipe is provided with the top of cylinder, it is characterised in that the madial wall of the cylinder is provided with accelerating solid The acceleration isolating construction of particle separation.

The surface in lower rotational gas flow along acceleration isolating construction is caused to proceed backspin by isolating construction on the wall of side, and Rotational gas flow under being formed on the bullet of bottom, and then in the pure air-flow of discharge pipe discharge.Due to only being carried out a separation chamber Separation, air flow path is short, efficiency high.Simultaneously because accelerating the presence of isolating construction so that the effect of solid and gas separation is improved, Higher purity is obtained in shorter path.

Further, the gear of the described direction of axis line setting along cylinder for accelerating isolating construction to include bar shaped Bar, described blend stop has many and along the circumferential uniform of cylinder, and the gap between blend stop forms the descending logical of solid particle Port between road, blend stop forms the entrance of solid particle.

Further, described blend stop is fixed on the medial surface of cylinder, with front surface, guide sides and dorsal surface, Front surface is the arcuate surface towards cylinder axial line, and front surface is tilted relative to the medial surface of cylinder and by same circle Circumferential direction is tilted, and guide sides are connection front surface and the arcuate surface relative with lower rotational gas flow, and dorsal surface is the positive table of connection The arcuate surface in face, the guide sides of the dorsal surface of a blend stop and adjacent blend stop form above-mentioned down going channel, and descending Passage is circle.

Further, described guide sides and dorsal surface are close in opposite directions so that blend stop formation interior thickness is less than positive table The thickness of end where face.

Further, described cylinder top is provided with the cover lid for all covering the upper port of above-mentioned down going channel, Described air guide channel of the cover lid with annular, air guide channel is connected with above-mentioned down going channel, on above-mentioned blast pipe also Connected provided with being in charge of with upper air guide channel.

Compared with prior art, this cyclone separator by the acceleration isolating construction on the wall of side cause lower rotational gas flow along The surface of isolating construction proceeds backspin, and is only separated a separation chamber, and air flow path is short, efficiency high.Simultaneously Due to accelerating the presence of isolating construction so that the effect of solid and gas separation is improved, obtain higher pure in shorter path Degree.

Embodiment

The following is specific embodiment of the utility model, further is made to the technical solution of the utility model with reference to accompanying drawing Description.

As shown in figure 1, this cyclone separator includes cylinder 1 and is arranged on the bullet 2 of the lower section of cylinder 1, in cylinder The upper end sidepiece of body 1 is provided with blast pipe 3, and discharge pipe 4 is provided with the top of cylinder 1, and the madial wall of cylinder 1 is provided with accelerating solid The acceleration isolating construction of particle separation.

It is specific to accelerate isolating construction as shown in Fig. 2 accelerating isolating construction to include the axial line along cylinder 1 of bar shaped The blend stop 5 that direction is set, blend stop 5 has many and along the circumferential uniform of cylinder 1, and the gap between blend stop 5 forms solid Port between the down going channel 6 of grain, blend stop 5 forms the entrance of solid particle.The solid and gas mixed gas that blast pipe 3 enters is vertical In the radial inflow of cylinder 1, lower rotational gas flow is produced, the centrifugal force that lower rotational gas flow is produced makes solid particle get rid of into down going channel In 6, due to the stop of down going channel 6, solid particle can be accelerated to accumulate in down going channel 6 on the wall of side, and lower rotational gas flow is pure Degree meeting more and more higher, improves efficiency.In order to ensure preferably producing for lower rotational gas flow, blend stop 5 is fixed on cylinder 1 Medial surface, and blend stop 5 is made into following structure, as shown in figure 3, blend stop 5 has front surface 51, guide sides 52 and dorsal surface 53, front surface 51 is the arcuate surface towards the axial line of cylinder 1, and front surface 51 is tilted relative to the medial surface of cylinder 1 And tilted by same circumferencial direction, allow the flow to smoothly produce cyclone by this structure, while energy leader air-flow enters Enter into down going channel 6, such as the arrow that Fig. 3 is marked, and guide sides 52 are connection front surface 51 and relative with lower rotational gas flow Arcuate surface, dorsal surface 53 is the arcuate surface of connection front surface 51, the dorsal surface 53 of a blend stop 5 and adjacent blend stop 5 guide sides 52 form above-mentioned down going channel 6, and down going channel 6 is circle.Therefore guide sides 52 and dorsal surface are passed through 53 structure continues guiding, and then can produce secondary lower rotational gas flow, makes product in the solid particle rapid decrease of side.And draw Lead side 52 and dorsal surface 53 is opposite close so that the formation interior thickness of blend stop 5 is less than the thickness of the place end of front surface 51, leads to Crossing this structure causes the place end of front surface 51 to produce low amplitude vibrations, can be quick by solid particle a small amount of on front surface 51 It is descending.

Prevent from causing the stifled of down going channel 6 not in time because draining to as early as possible drain the solid particle in down going channel 6 Plug, the cover lid 7 for all covering the upper port 61 of down going channel 6 is provided with the top of cylinder 1, and cover lid 7 has the air guide of annular Passage 71, air guide channel 71 is connected with down going channel 6, is additionally provided with blast pipe 3 and is in charge of 31 and is connected with air guide channel 71.

Rotational gas flow is formed on bullet 2 afterwards clean air-flow is discharged from discharge pipe 4.
