Technical Field

[0001] The present invention relates to the technical field of dust collectors, and specifically, to a novel and efficient dust collector. Background Art

[0002] During the industrial production process, a large amount of waste gas containing dust is generated. If these dusts are directly discharged into the atmosphere, it will not only cause serious environmental pollution, but also endanger human health. Traditional dust collectors have problems such as low dust removal efficiency, large equipment volume, high operating cost, and difficult maintenance. For example, in a common bag dust collector, the bags are easily blocked and need to be frequently replaced, increasing the operating cost and maintenance workload; while the electrostatic dust collector has certain requirements for the specific resistance of dust, and the dust removal effect for high specific resistance dust is not good. Developing an efficient, energy-saving, compact and easy-to-maintain dust collector has important practical significance. Therefore, a novel and efficient dust collector is proposed. Summary of the Invention

[0003] The purpose of the present invention is to provide a novel and efficient dust collector to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A novel and efficient dust collector includes an upper adsorption purification box, a cyclone inlet chamber, and a lower impact water tank. The upper adsorption purification box is connected to the cyclone inlet chamber, the lower impact water tank is connected to the lower part of the cyclone inlet chamber. A cyclone is installed outside the cyclone inlet chamber, and the external dust-containing gas is connected to the air inlet of the cyclone. A spray pipe is connected to the cyclone, and the water outlet end of the spray pipe penetrates through the outer wall of the cyclone. A baffle is fixedly connected inside the cyclone inlet chamber, and the baffle is located above the air outlet of the cyclone. A cyclone water body dust removal structure is installed inside the cyclone inlet chamber, and dust removal water is stored inside the lower impact water tank, and the lower end of the cyclone water body dust removal structure is inserted into the dust removal water.

[0005] Preferably, the cyclone dust removal structure includes a header air distribution box, the header air distribution box is installed inside the cyclone inlet chamber, a row of cyclone pipes is installed below the header air distribution box, and the lower air outlet of the row of cyclone pipes is inserted into the dust removal water.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figure 1 - Figure 2 shown, a novel and efficient dust collector of the present application includes an upper adsorption purification box 100, a cyclone air inlet chamber 108, and a lower impact water tank 105. The upper adsorption purification box 100 is connected to the cyclone air inlet chamber 108, the lower impact water tank 105 is connected below the cyclone air inlet chamber 108, a cyclone 103 is installed outside the cyclone air inlet chamber 108, an external dust-laden gas pipeline is connected to the air inlet of the cyclone 103, a spray pipe 104 is connected to the cyclone 103, and the water outlet end of the spray pipe 104 penetrates the outer wall of the cyclone 103. A baffle 109 is fixedly connected inside the cyclone air inlet chamber 108, and the baffle 109 is located above the air outlet of the cyclone 103. A cyclone water body dust removal structure is installed inside the cyclone air inlet chamber 108, the lower impact water tank 105 stores dust removal water, and the lower end of the cyclone water body dust removal structure is inserted into the dust removal water.

[0019] Specifically, during the use process, an industrial dust removal pipe is connected through the cyclone 103, and the industrial dust removal pipe continuously conveys the dust-laden gas into the cyclone 103. When the dust-laden gas continuously enters the cyclone 103, primary dust removal is carried out by the water flow sprayed from the spray pipe 104. After primary dust removal, the gas is continuously conveyed into the cyclone air inlet chamber 108. After the gas continuously enters the cyclone air inlet chamber 108, it will first be blocked by the baffle 109, and the larger dust particles in the gas are blocked by the baffle 109 and fall off and are removed. The smaller dust particles are sprayed again by the spray pipe 104 and enter the lower impact water tank 105 together with the air flow. After the dust falls into the lower impact water tank 105, it will come into contact with the dust removal water inside the lower impact water tank 105, and secondary dust removal is carried out through the cyclone water body dust removal structure.

[0020] As Figure 1 - Figure 2 shown, the cyclone dust removal structure includes a header air distribution box 200, the header air distribution box 200 is installed inside the cyclone air inlet chamber 108, a row of cyclone pipes 201 is installed below the header air distribution box 200, and the lower air outlet of the row of cyclone pipes 201 is inserted into the dust removal water.

[0021] Specifically, in the cyclone dust removal structure, after the gas enters the interior of the lower impact water tank 105, by continuously injecting air flow into the interior of the multiple row-connected cyclone tubes 201, the air flow with dust will also enter the interior of the row-connected cyclone tubes 201. Inside the row-connected cyclone tubes 201, there is a spiral channel (not shown in the figure), and the spiral channel is a tapered structure, with the pipe diameter gradually decreasing from the air inlet end to the air outlet end. This can enhance the rotation speed of the gas and increase the centrifugal force, thereby more effectively separating dust particles. And after the air flow with dust is ejected together through the air outlet of the row-connected cyclone tubes 201, the ejected air flow has a greater impact force and is ejected from the air outlet of the row-connected cyclone tubes 201 at a higher speed, impacting the dust removal water and thus hitting up a large amount of foam and water droplets, so as to achieve the purpose of purifying the air.

[0022] Furthermore, the multiple row-connected cyclone tubes 201 are in a parallel structure, which increases the gas processing capacity and improves the overall dust removal efficiency of the dust collector. Moreover, this structure makes the volume of the dust collector relatively small, facilitating installation and maintenance.

[0023] As Figure 1 and Figure 2 shown, a demister 500 is installed inside the upper adsorption purification box 100, and a purified air outlet pipe 101 is connected to the outside of the upper adsorption purification box 100. One end of the purified air outlet pipe 101 away from the upper adsorption purification box 100 is connected to a negative pressure fan 102.

[0024] Specifically, after the gas with dust is dust-removed by the row-connected cyclone tubes 201 and the dust removal water, the staff can turn on the negative pressure fan 102. When the negative pressure fan 102 is turned on, the purified gas, under the negative pressure of the negative pressure fan 102, passes through the demister 500 and is discharged by the negative pressure fan 102, and the water droplets contained in the purified gas are removed by the demister 500.

[0025] As Figure 2 shown, a spray inlet pipe 202 is installed inside the lower impact water tank 105. A plurality of spray holes are opened on the outside of the spray inlet pipe 202. By continuously injecting water flow into the interior of the spray inlet pipe 202 through an external water pipe, the water flow can be sprayed onto the side wall surface of the lower impact water tank 105 through the externally opened spray holes, thereby flushing the side wall surface of the lower impact water tank 105, and the water flow ejected through the spray holes is used to supplement the dust removal water inside the lower impact water tank 105.

[0026] As Figure 2 and Figure 3 shown, an overflow pipe 203 is connected to the inside of the lower impact water tank 105. The water outlet of the overflow pipe 203 penetrates the outer wall of the lower impact water tank 105, and the water inlet position of the overflow pipe 203 is higher than that of the spray inlet pipe 202.

[0027] Specifically, through the setting of the overflow pipe 203, when the water flow inside the lower impact water tank 105 is excessive and the water level reaches the inlet position of the overflow pipe 203, the water flow will be discharged to the outside through the overflow pipe 203, preventing the water flow from continuously accumulating inside the lower impact water tank 105.

[0028] As Figure 1 - Figure 3 shown, an electric sewage discharge valve 106 is connected to the bottom of the lower impact water tank 105, and a liquid level gauge 300 is installed on the electric sewage discharge valve 106. After the dust removal water for purifying gas is used for a certain period of time, it needs to be replaced because the water contains a large amount of dust. When replacing the water, the electric sewage discharge valve 106 is opened, and the sewage containing a large amount of dust is discharged through the drain port. When the sewage is basically drained, the liquid level gauge 300 controls the solenoid valve installed on the water inlet main pipe to open (the water supply pressure is 2 - 4 kg / cm), and the water is sprayed out through the spray holes outside the header air distribution box 200 by the water inlet pipe, washing the bottom of the lower impact water tank 105 clean. After washing, the electric sewage discharge valve 106 is closed, and the water surface in the lower impact water tank 105 rises. When the water surface rises to the height required for dust removal, the continuous supply of water flow to the spray water inlet pipe 202 is cancelled, and the water supply is interrupted. The excess water in the box body is discharged through the overflow pipe 203: At this time, the dust collector can enter the working state.

[0029] As Figure 1 shown, four support feet 107 are installed outside the lower impact water tank 105, and the lower impact water tank 105 is supported by the four support feet 107.

[0030] As Figure 1 shown, an observation window 400 is installed outside the upper adsorption purification box 100. Through the setting of the observation window 400, the inside of the swirl air inlet chamber 108, the upper adsorption purification box 100, and the lower impact water tank 105 can be observed. The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Through the dual effects of the centrifugal separation of the row-connected swirl pipes 201 and the water impact of the lower impact water tank 105, the dust particles in the dust-containing gas can be effectively removed. The structural design of multiple row-connected swirl pipes 201 in parallel enables the dust collector to have a relatively small volume and a small floor area when dealing with a large gas volume, facilitating installation and use in various industrial sites. The present invention uses water as the dust removal medium, eliminating the need for expensive filter materials or complex electrostatic equipment, resulting in low operating costs. At the same time, due to the high dust removal efficiency, the cost of subsequent waste gas treatment is reduced, and it is easy to maintain: The structure is simple, without complex vulnerable parts. The daily maintenance mainly involves regularly cleaning the sewage outlet and checking the water level control system, with a small maintenance workload and low maintenance costs.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
