Description
Technical Field
[0001] This utility model relates to the field of baghouse dust collection technology, specifically a high-efficiency pre-dust collection device for industrial waste gas baghouse dust collection equipment. Background Technology
[0002] Pre-dust collection devices are the "vanguard" at the front end of baghouse dust collection systems. Their core function is to pre-treat dust-laden gas, reducing the dust concentration and particle kinetic energy entering the baghouse area, thereby protecting the core filter bags, extending the cleaning cycle, and improving the overall efficiency and stability of the system. The most commonly used pre-dust collection device is the cyclone dust collector. Cyclone dust collectors utilize the strong rotational motion generated when dust-laden gas enters the device tangentially, causing the dust to be thrown against the wall under centrifugal force and then slide down the wall into the ash hopper. The purified gas is discharged from the central exhaust pipe. However, existing cyclone dust collectors cannot remove highly viscous and moist dust, which easily adheres to the inner wall, preventing the device from effectively removing dust. Therefore, we propose a high-efficiency pre-dust collection device for industrial waste gas baghouse dust collection equipment. Utility Model Content
[0003] The present invention aims to solve the problems existing in the prior art or related technologies.
[0004] Therefore, the technical solution adopted by this utility model is as follows: a high-efficiency pre-dust collection device for industrial waste gas bag dust collectors, including a cyclone dust collector cylinder, an air inlet pipe, an exhaust component, a water spray component, and a water mist component. The air inlet pipe is fixedly installed on the outside of the cyclone dust collector cylinder, the exhaust component is fixedly installed on the top of the cyclone dust collector cylinder, the water spray component includes a first ring pipe fixedly connected to the inside of the cyclone dust collector cylinder, a connecting pipe fixedly installed on the right side of the first ring pipe, and a plurality of water spray pipes fixedly connected to the bottom of the first ring pipe, and the water mist component includes a vertical pipe fixedly connected to the bottom of the first ring pipe, a second ring pipe fixedly installed at the bottom of the vertical pipe, and a plurality of nozzles fixedly connected to the bottom of the second ring pipe.
[0005] Preferably, flanges are fixedly installed on the left side of the air inlet pipe and at the bottom of the cyclone dust collector, and the lower part of the cyclone dust collector is conical.
[0006] Preferably, the exhaust assembly includes an exhaust pipe fixedly connected to the top of the cyclone dust collector cylinder, and a flange is fixedly provided at the top end of the exhaust pipe.
[0007] Preferably, the exhaust assembly further includes an adjusting pipe inserted outside the exhaust pipe, a cylinder fixedly installed at the top of the adjusting pipe, and a demister fixedly installed inside the adjusting pipe.
[0008] Preferably, the connecting pipe is fixedly connected to the tap water pipe, and the inner side of the connecting pipe is provided with internal threads.
[0009] Preferably, the plurality of nozzles and the plurality of water spray pipes are arranged in a ring.
[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The connecting pipe of the water spray component can be connected to a tap water pipe, so that tap water can be transported to the water spray pipe through the connecting pipe and the first ring pipe in sequence. The sprayed water will form a water curtain on the inner wall of the cyclone dust collector, effectively avoiding the problem that sticky and moist dust is easy to stick to the inner wall and cause the device to fail to remove dust. At the same time, the vertical pipe and the second ring pipe can transport water to the nozzle for spraying. The sprayed water mist will increase in weight after colliding with the rotating dust. The increased weight of the particles is more easily thrown out by centrifugal force, so as to improve the dust removal efficiency. Then, the cylinder of the exhaust component can drive the regulating pipe to move up and down, thereby adjusting the exhaust length to improve the separation performance and reduce the system energy consumption.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0022] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a high-efficiency pre-dust collection device for an industrial waste gas bag filter dust collector.
[0023] Example 1:
[0024] Reference Figure 1-4 This is the first embodiment of the present utility model. This embodiment provides a high-efficiency pre-dust collection device for industrial waste gas bag dust collectors, including a cyclone dust collector cylinder 100, an air inlet pipe 200, an exhaust component 300, a water spray component 400, and a water mist component 500.
[0025] Specifically, the air inlet pipe 200 is fixedly installed on the outside of the cyclone dust collector 100. Flanges are fixedly installed on the left side of the air inlet pipe 200 and the bottom of the cyclone dust collector 100. The lower part of the cyclone dust collector 100 is conical. In use, the industrial waste gas conveying device can be fixed through the air inlet pipe 200 so that the industrial waste gas can be conveyed into the cyclone dust collector 100. Then, dust can be discharged through the bottom of the cyclone dust collector 100.
[0026] Specifically, the exhaust assembly 300 is fixedly installed on the top of the cyclone dust collector 100. The exhaust assembly 300 includes an exhaust pipe 301 fixedly connected to the top of the cyclone dust collector 100, with a flange fixedly installed at the top of the exhaust pipe 301. The exhaust assembly 300 also includes an adjusting pipe 302 inserted outside the exhaust pipe 301, a cylinder 303 fixedly installed at the top of the adjusting pipe 302, and a demister 304 fixedly installed inside the adjusting pipe 302. In use, the purified gas can be discharged through the exhaust pipe 301, and the height of the adjusting pipe 302 and the demister 304 can be adjusted by the cylinder 303 to optimize the airflow residence time, improve separation efficiency, control pressure loss, and reduce system energy consumption. Then, the moisture in the gas can be removed by the demister 304.
[0027] Specifically, the water spray assembly 400 includes a first annular pipe 401 fixedly connected to the inner side of the cyclone dust collector cylinder 100, a connecting pipe 402 fixedly disposed on the right side of the first annular pipe 401, and several water spray pipes 403 fixedly connected to the bottom of the first annular pipe 401. The connecting pipe 402 is fixedly connected to a tap water pipe, and the inner side of the connecting pipe 402 is provided with an internal thread. In use, tap water can be delivered to several water spray pipes 403 through the connecting pipe 402 and the first annular pipe 401. The sprayed water will slowly flow down along the inner wall of the cyclone dust collector cylinder 100, thereby forming a water curtain, which can quickly remove dust and avoid the problem that sticky and moist dust is easy to stick to the inner wall, causing the device to fail to remove dust.
[0028] Specifically, the water mist assembly 500 includes a vertical pipe 501 fixedly connected to the bottom of the first ring pipe 401, a second ring pipe 502 fixedly disposed at the bottom of the vertical pipe 501, and a plurality of nozzles 503 fixedly connected to the bottom of the second ring pipe 502. The plurality of nozzles 503 and the plurality of water spray pipes 403 are arranged in a ring. In use, water can be transported to the plurality of water spray pipes 403 through the vertical pipe 501 and the second ring pipe 502 and sprayed out. The sprayed water mist can collide with the dust and increase its weight, thereby improving the dust removal efficiency.
[0029] The working principle and usage process of this utility model are as follows: When in use, the connecting pipe 402 of the water spray assembly 400 can be connected to a tap water pipe. After connection, tap water can be transported through the connecting pipe 402 and the first ring pipe 401 to several water spray pipes 403 for spraying. The sprayed water will form a water curtain inside the cyclone dust collector 100, which can carry away sticky and moist dust. At the same time, water will be transported through the vertical pipe 501 and the second ring pipe 502 to several nozzles 503 for spraying. The sprayed water mist can collide with the dust. After the collision, the moist dust will be automatically discharged through the bottom of the cyclone dust collector 100 due to gravity.
