The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, a wet dust collector includes a cyclone dust collector 2 and a cyclone spray tower 3, the cyclone spray tower 3 has a first air inlet 21 and a first air outlet 22, the cyclone dust collector 2 has a second air inlet 311 and a second air outlet 312, the first air outlet 22 is communicated with the second air inlet 311 through a pipe 4, and the cyclone dust collector 2 is disposed above the cyclone spray tower 3.

In this application, through combining cyclone 2 and air-whirl spray column 3, can realize efficient dust removal effect. The cyclone spray tower 3 forms a rotary air flow by spraying liquid, further wets and captures suspended substances, removes a part of suspended substances in advance, and the cyclone dust collector 2 separates solid particles from the air flow by centrifugal force.

The cyclone dust collector 2 and the cyclone spray tower 3 in the device form a multi-stage treatment system. The air flow enters the cyclone spray tower 3 from the first air inlet 21, and after the spraying and rotating action, part of solid particles are humidified and separated. The airflow is then coupled to the cyclone 2 via conduit 4 and further centrifuged to exit the second outlet 312. Such a multistage treatment can improve the treatment effect and reduce the discharged solid particles. The cyclone dust collector 2 is arranged above the cyclone spray tower 3, so that the space occupation of the whole device is small. This is very advantageous for those places where space is limited or vertical installation is required. At the same time, this arrangement is also easy to operate and maintain.

Specifically, the cyclone spray tower 3 is provided with a water tank 33, a return pipe 34, a pipe body 31, a spray system 32, a swirl plate 35, a water pump 36 and a water pipe 37, wherein the water tank 33 is provided with a water inlet 331, the return pipe 34 is fixed at the position of the water inlet 331 and stretches into the water tank 33, the pipe body 31 is arranged on the water tank 33 and is communicated with the water tank 33, the spray system 32 and the swirl plate 35 are arranged in the pipe body 31 from top to bottom, the first air outlet 22 is positioned above the spray system 32, the first air inlet 21 is positioned below the swirl plate 35, the water pump 36 is connected with the water tank 33, and the water pipe 37 is connected with the water pump 36 and the spray system 32.

The cyclone spray tower 3 is equipped with a high efficiency spray system 32 that is capable of humidifying and capturing suspended matter in the airstream by spraying an appropriate amount of water or liquid. The spray system 32 is arranged in the pipe body 31 from top to bottom, so that the spray liquid can uniformly cover the air flow area, and a better humidifying effect is provided. The swirl plate 35 is located below the tubular body 31 and, by its particular construction and design, can direct the air flow to create a swirling effect. The presence of swirl plates 35 provides sufficient contact between the gas stream and the spray liquid to increase the chances of particle wetting and separation. Swirl plate 35 can also help stabilize the flow of gas and liquid streams, enhancing the process.

Specifically, the cyclone dust collector 2 is provided with a dust discharge port 23, a liquid discharge pipe 24 is connected to the dust discharge port 23, the lower end of the liquid discharge pipe 24 passes through a return pipe 34 and is communicated with the inside of a water tank 33, and a space is arranged between the outer wall of the liquid discharge pipe 24 and the return pipe 34.

By connecting the drain 24 at the outlet of the cyclone 2, the humidified particulate matter and liquid can be effectively discharged. The centrifugal force in the cyclone 2 causes the solid particles and liquid droplets to settle to the bottom and then smoothly discharge through the discharge pipe 24. The location and spacing of the connection of drain 24 to return tube 34 ensures the smoothness and effectiveness of the drain.

The outer wall of the drain pipe 24 is spaced from the return pipe 34, and the design is such that the liquid in the cyclone spray tower 3 and the drain of the cyclone dust collector 2 do not affect each other.

After the water is added to tank 33, return pipe 34 and the lower end of drain pipe 24 need to be completely submerged.

Specifically, the device further comprises a branch pipe 371 connected to the water pipe 37, the other end of the branch pipe 371 is connected to the pipeline 4 and extends into the pipeline 4, and the end of the branch pipe 371 is provided with a water spray port.

The branch pipe 371 extends into the pipeline 4, and then direct water spraying is carried out, so that suspended matters in the air are further captured and removed, and the removal rate of the suspended matters is improved.

By spraying water, a small amount of dust and paint mist adhering to the pipe 4 can be washed, and the dust and paint mist can flow back into the water tank 33.

Specifically, the water tank 33 is provided with a drain pipe 332, a valve 3321 is provided on the drain pipe 332, an overflow pipe 3322 is provided on the upper portion of the water tank 33, and the overflow pipe 3322 is connected with the drain pipe 332 and is connected to one end of the valve 3321 far from the water tank 33.

The water tank 33 provides a convenient drain function through a combination of the drain tube 332 and the valve 3321. An operator can smoothly discharge the waste water or impurities in the water tank 33 by opening the valve 3321 to maintain the cleaning and normal operation of the water tank 33. An overflow tube 3322 at the upper portion of the tank 33 is connected to a port of the valve 3321 remote from the tank 33. When the water level in the water tank 33 exceeds the safety limit, the excessive water is discharged through the overflow pipe 3322, so that the damage or potential safety hazard caused by overflow of the water tank 33 is avoided. This design provides control and protection of the water level.
