Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a high-efficiency venturi filter layer dust collector. Background Technology

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas it can handle, the resistance loss of gas passing through the dust collector, and the dust removal efficiency.

[0003] In the existing technology, a Venturi dust collector with application number CN202222770820.1 is provided. This application sets up a demister to improve the atomization effect of the water flow, thereby reducing the inlet airflow velocity, reducing the resistance of the Venturi tube and the entire dust collector, changing the airflow direction of the first gas-liquid separator, solving the problem that small droplets are easily carried out by the internal swirling flow in the first gas-liquid separator, and enhancing the airflow separation effect. However, when the water vapor contains a small amount of dust, it will still rise with the air and be discharged. At the same time, the discharged air contains a lot of water vapor, resulting in a large consumption of water resources. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency venturi filter layer dust collector that can solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency venturi filter layer dust collector, comprising a cylinder: A filter assembly, which is installed inside the cylinder, is used to filter the gas inside the cylinder. The filtering component includes: An installation groove is formed in the middle of the cylinder. A filter frame is slidably connected inside the installation groove. Filter plates are fixedly installed at the upper and lower ends inside the filter frame. Filter packing is arranged between the filter plates inside the filter frame. A fixing plate is fixedly installed on the right side of the filter frame, and a sealing ring is adhered to the left side of the fixing plate.

[0006] By adopting the above technical solution, the filter plate and filter media in the filter frame filter polluted air, reducing dust, impurities and water vapor in the discharged air.

[0007] A further feature of this invention includes: A locking component is installed on the side of the filter assembly and is used to lock the internal structure of the filter assembly.

[0008] The locking component includes: A locking block is fixedly installed at the front and rear ends of the cylinder on the left side of the fixing plate. Limiting blocks are fixedly installed at the front and rear ends of the fixing plate. A threaded column is rotatably connected inside the locking block. A locking knob is threadedly connected to the outside of the threaded column. A rubber pad is glued to the left side of the locking knob. A slot is opened inside the limiting block.

[0009] By adopting the above technical solution, the rotation of the locking knob causes the rubber pad to fit against the limit block, thereby locking the limit block and facilitating the disassembly and assembly of the fixing plate.

[0010] A further feature of this invention includes: A mixing component, installed on the left side of the cylinder, is used to perform dust removal on the gas introduced into the cylinder.

[0011] The hybrid component includes: A drain pipe is fixedly installed at the lower end of the cylinder, a fan is fixedly installed at the upper end of the cylinder, a connecting pipe is fixedly installed at the lower left end of the cylinder, a diffuser is fixedly installed at the upper end of the connecting pipe, and a Venturi tube is fixedly installed on the left side of the diffuser.

[0012] By adopting the above technical solution, polluted air enters the venturi tube and accelerates the impact of water mist, causing the water mist to adsorb dust and thus achieving the interception and filtration of dust in the air.

[0013] A further feature of this invention includes: A spraying assembly, which is installed inside the mixing assembly, is used to introduce water into the mixing assembly.

[0014] The spraying assembly includes: A spray pipe is fixedly installed inside a venturi tube. An annular tube frame is fixedly installed on the outside of the spray pipe. An inlet pipe is fixedly installed at the lower end of the annular tube frame. A nozzle is fixedly installed on the side of the spray pipe near the central axis.

[0015] By adopting the above technical solution, multiple spray pipes spray a large amount of water mist into the venturi tube, ensuring that dust and impurities come into contact with the water mist and reducing the dust content in the polluted air.

[0016] The beneficial effects of this utility model are: The filter assembly of this utility model reduces impurities and moisture in the discharged air by using a filter plate and filter packing, thereby improving the dust collector's filtration effect on polluted air. At the same time, the locking assembly uses a locking knob and a threaded post to facilitate the disassembly and installation of the filter frame, and to facilitate the replacement and cleaning of the filter plate and filter packing, thereby improving the dust collector's filtration efficiency.

[0017] The mixing component of this invention uses a venturi tube and a drain pipe to facilitate the filtration of polluted air and improve the filtration and separation efficiency of polluted air. At the same time, the spraying component uses multiple spray pipes to spray a large amount of water mist into the venturi tube, so that the polluted air is evenly contacted with the water mist, which facilitates the adsorption of dust by the water mist.

[0022] Reference Figure 1-6A high-efficiency venturi filter layer dust collector includes a cylinder 1, a filter assembly 2, a locking assembly 3, a mixing assembly 4, and a spraying assembly 5. The filter assembly 2 is installed inside the cylinder 1 and is used to filter the gas inside the cylinder 1. The locking assembly 3 is installed on the side of the filter assembly 2 and is used to lock the internal structure of the filter assembly 2. The mixing assembly 4 is installed on the left side of the cylinder 1 and is used to perform dust removal on the gas entering the cylinder 1. The spraying assembly 5 is installed inside the mixing assembly 4 and is used to introduce water into the mixing assembly 4.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The filter assembly 2 includes: an installation groove 201 located in the middle of the interior of the cylinder 1; a filter frame 202 slidably connected inside the installation groove 201; filter plates 203 fixedly installed at the upper and lower ends inside the filter frame 202; filter filler 204 disposed between the filter plates 203 inside the filter frame 202; a fixing plate 205 fixedly installed on the right side of the filter frame 202; and a sealing ring 206 bonded to the left side of the fixing plate 205. The locking assembly 3 includes: a locking block 301 fixedly installed at the front and rear ends of the cylinder 1 on the left side of the fixing plate 205; limit blocks 302 fixedly installed at the front and rear ends of the fixing plate 205; a threaded post 303 rotatably connected inside the locking block 301; a locking knob 304 threadedly connected to the outside of the threaded post 303; a rubber pad 305 bonded to the left side of the locking knob 304; and a slot 306 opened inside the limit block 302.

[0024] In this invention, when the dust-laden water mist mixed by the mixing component 4 enters the cylinder 1, the water mist containing larger dust particles has a larger mass, causing it to settle inside the cylinder 1. When the dust particles in the water mist are smaller, they are carried upwards by the mixing component 4, thus rising and contacting the filter frame 202. The filter plate 203 on the filter frame 202 intercepts the smaller dust particles. At the same time, the filter packing 204, which is a PVC multi-faceted hollow sphere, adsorbs and intercepts moisture in the rising gas, reducing impurities and moisture in the discharged air, improving the dust collector's filtration effect on polluted air, and increasing filtration capacity. The sealing ring 206 on the fixing plate 205 is tightly attached to the cylinder 1 to prevent air leakage inside the cylinder 1. The filter plate 203 and filter... When cleaning and replacing the packing 204, rotate the locking knob 304 on the threaded column 303 to disengage the rubber pad 305 from the limit block 302. Then, rotate the threaded column 303 on the locking block 301 to disengage the threaded column 303 from the empty groove 306 on the limit block 302, releasing the lock on the fixing plate 205. Then, pull the fixing plate 205 to disengage it from the cylinder 1 and pull the filter frame 202 out of the mounting groove 201. This facilitates the disassembly and installation of the filter frame 202, and the replacement and cleaning of the filter plate 203 and filter packing 204. This prevents the filter assembly 2 from becoming clogged and affecting the filtration efficiency, ensuring the cleanliness of the filter plate 203 and filter packing 204 and improving the filtration efficiency of the dust collector.

[0025] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The mixing component 4 includes: a drain pipe 401 fixedly installed at the lower end of the cylinder 1; a blower 402 fixedly installed at the upper end of the cylinder 1; a connecting pipe 403 fixedly installed at the lower left end of the cylinder 1; a diffuser 404 fixedly installed at the upper end of the connecting pipe 403; and a Venturi tube 405 fixedly installed on the left side of the diffuser 404. The spraying component 5 includes: a spraying pipe 501 fixedly installed inside the Venturi tube 405; an annular pipe support 502 fixedly installed on the outside of the spraying pipe 501; an inlet pipe 503 fixedly installed at the lower end of the annular pipe support 502; and a nozzle 504 fixedly installed on the side of the spraying pipe 501 near the central axis.

[0026] In this invention, when filtering and removing dust from polluted air, the polluted air is introduced into a venturi tube 405. The middle section of the venturi tube 405 is designed as a narrow area to increase the airflow velocity in that section. This causes the polluted air to collide at high speed with the water mist pumped in by the spraying assembly 5, causing dust and impurities in the air to combine with water droplets in the water mist. The polluted air then enters a diffuser tube 404, where the larger internal space slows the airflow velocity. It then enters the cylinder 1 through a connecting pipe 403. Larger water droplets in the water mist settle to the bottom of the cylinder 1. Wastewater is discharged through drain pipe 401. The blower 402 at the top of cylinder 1 facilitates the upward movement of air inside cylinder 1, which facilitates the filtration of polluted air and improves the filtration and separation efficiency of polluted air. When water mist is pumped into venturi tube 405, water is pumped into inlet pipe 503. Then, the water enters the spray pipe 501 through annular pipe frame 502 and is sprayed out in the form of water mist through nozzle 504. Through the cooperation of multiple spray pipes 501, a large amount of water mist is sprayed into venturi tube 405, so that polluted air is evenly contacted with water mist, which facilitates the adsorption of dust by water mist.
