The vast majority of the swirling air flow flows helically down the walls from the cylinder towards the cone. In addition, the particles are thrown towards the wall under the action of centrifugal force, and once the dust particles are contacted with the wall, the inertial force is lost, and the momentum of downward axial speed near the wall falls down along the wall surface, enters the ash discharge pipe and falls into the collecting bag from the powder outlet. The descending outward cyclone flow continuously flows into the center part of the separator in the descending process to form centripetal radial airflow, and the part of the airflow forms upward rotating inward cyclone flow, and the purified gas is discharged out of the separator through the gas outlet pipe. In the prior art, the power for driving the internal rotation gas to flow out of the wet cyclone separator body is connected with the air outlet pipe through the air extraction equipment, so that pressure difference is formed, the internal rotation gas is taken out, and another small part of gas flowing in from the air inlet pipe flows downwards along the outer side of the air outlet pipe through the top cover of the wet cyclone separator, and when reaching the lower end of the air outlet pipe, the gas is converged with the ascending internal rotation gas flow and then enters the air outlet pipe, so that gas flow short-circuit flow is formed, and the separation effect is influenced.

The wet cyclone separator 100A includes an outlet duct 103, and the outlet duct 103 is located at a central position of the top of the separator body 101, which in turn allows the cyclone gas to flow out. The air inlet of outlet duct 103 sets up in separator body 101, and outlet duct 103 is connected with separator body 101, and the position of the air inlet of outlet duct 103 is less than the position of separator body 101's air inlet, has guaranteed by adopting above-mentioned structure that the gas of letting in can fully carry out centrifugal separation, if the position of the air inlet of outlet duct 103 is higher than the position of separator body 101's air inlet relatively, then the gas of waiting to separate of letting in is directly sucked away by outlet duct 103 easily, and does not carry out the separation.
The wet cyclone separator 100A further comprises a blocking member 110 for reducing short-circuit flow formed by air flow when the air outlet pipe 103 is in air inlet, the blocking member 110 is provided with a through hole 111, the through hole 111 is communicated with the air inlet of the air outlet pipe 103, so that air can smoothly flow out through the air outlet pipe 103, the blocking member 110 is arranged in the separator body 101, the blocking member 110 is fixedly connected with the air inlet end of the air outlet pipe 103, the air outlet pipe 103 is arranged to extract air below the blocking member 110, the air cannot be extracted from the air inlet of the air outlet pipe 103 and the top of the separator body 101, the short-circuit flow of the air flow above the air outlet pipe 103 is restrained, meanwhile, the influence distance of ascending air flow below the air outlet pipe 103 is longer, and the exhaust effect is improved.

The air extractor 104 provides power for the flow of air, and the air extractor 104 can be an air extracting pump or other equipment capable of realizing air extraction.
Because the air extractor 104 is used, the air pressure in the separator body 101 is lower than the external air pressure, and then the air near the dust outlet pipe 102 is easily sucked into the dust outlet pipe 102 and then enters the separator body 101, so that pollution is caused, and the separation effect is reduced. Therefore, in order to solve this technical problem, the wet cyclone separator 100A further includes a liquid seal box 120 for liquid sealing the dust outlet pipe 102, the liquid seal box 120 is placed with liquid therein, the liquid seal box 120 is disposed outside the separator body 101, and the discharge port of the dust outlet pipe 102 is disposed in the liquid seal box 120 and is located below the liquid level.

Example 3
Referring to fig. 4, the wet cyclone 100C according to the present embodiment has substantially the same structure as the wet cyclone 100B according to embodiment 2, except that a cone-shaped hood 140 is added.
Referring to fig. 5, the wet cyclone separator 100C further includes a cone-shaped cap 140 for converting the cyclone gas generated from the wet cyclone separator 100C into a cyclone-free gas, the cone-shaped cap 140 being disposed in the separator body 101 and connected to the separator body 101, the cone-shaped cap 140 being provided with a plurality of flow holes 141, the cone-shaped cap 140 being opposite to the gas outlet pipe 103. The upward internal rotation air flow pumped by the air outlet pipe 103 causes the upper surface and the lower surface of the conical hood 140 to generate a pressure gradient gradually decreasing from bottom to top, and the air flow is changed into upward non-rotation air flow through the air holes of the conical hood 140 under the action of the pressure gradient, so that the pressure loss of the air flow at the air outlet pipe 103 of the traditional wet cyclone separator is reduced, and then the energy consumption is reduced.
It should be noted that, the conical hood 140 only acts on the internal airflow, but does not act on the external airflow, and cannot prevent the external airflow from flowing, so the conical hood 140 is relatively close to the bottom of the separator body 101, and the size of the conical hood 140 is suitably smaller, so that the whole separator body 101 cannot be fully covered, and the influence of the external airflow on the conical hood is avoided. Preferably, the length of the projection of the conical hood 140 on the projection plane is not longer than the diameter of the air outlet pipe 103.
Further, the plurality of the flow holes 141 are annularly arranged along the circumference of the cone-shaped hood 140, and the top of the cone-shaped hood 140 is relatively close to the barrier 110. That is, the inner diameter of the cone-shaped hood 140 gradually decreases in the direction in which the swirling gas flows.
It is further preferred that the side of the cone cap 140 in contact with the pronating gas is provided with an adhesive layer 144. When the cyclone airflow passes through the conical hood 140, the adhesion layer 144 can adhere the residual fine particles in the airflow, so that the dust removal effect is further improved. It should be noted that the adhesive layer 144 may be made of a resin, a silica gel, or the like.
Alternatively, the conical hood 140 may be directly immersed, so that the surface of the conical hood 140 is wet, and then adhesion of particles may be performed.
It should be noted that the cone-shaped hood 140 may be disposed in the wet cyclone separator of embodiment 1, or the various embodiments may be combined within the scope of the present invention.
It should be noted that, in this embodiment, only 1 example of the taper caps 140 is illustrated, but the number of taper caps 140 may be increased according to production requirements, for example, 2 taper caps 140, 3 taper caps 140 or 4 taper caps 140 may be provided, and when a plurality of taper caps 140 are provided, the top of each taper cap 140 is located on the same straight line, so that smooth passage of air flow is ensured.
In summary, the wet cyclone separator provided by the invention inhibits the short-circuit flow of the air flow above the air outlet pipe by arranging the blocking piece, and simultaneously ensures that the influence distance of the ascending air flow below the air outlet pipe is longer, thereby improving the transportation effect of the air outlet pipe. And set up the steam pipe, can the dust granule that the entrapment particle diameter is less for dust viscosity increases, gathers into bigger granule easily, promotes separation effect. The conical hood is arranged to enable the upper surface and the lower surface of the conical hood to generate pressure gradient gradually decreasing from bottom to top, and air flow is changed into upward non-swirling air flow through the circulation hole of the conical hood under the action of the pressure gradient, so that the pressure loss of the air flow of the traditional wet cyclone separator at the air outlet pipe is reduced, and the energy consumption is reduced.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
