Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically a dust removal device for a waterworks chemical dosing room. Background Technology

[0002] Waterworks frequently use various water treatment chemicals, which are generally stored in the chemical dosing room. The proper functioning of the equipment in the dosing room directly affects the overall water treatment effect of the plant, and can even cause some water treatment units to malfunction completely, resulting in substandard effluent from the plant.

[0003] In existing technologies, most waterworks chemical dosing rooms use a method of adding powdered chemicals to a silo, which are then pumped to a solution tank and storage tank. The process of adding the chemicals to the silo is prone to dust dispersion, causing pollution in the dosing room. The dust in waterworks chemical dosing rooms mainly consists of coagulants (such as polyaluminum chloride) and lime powder, characterized by fine particle size and easy moisture absorption. The challenge in dust removal lies in achieving efficient filtration without clogging. If the dispersed dust can be recovered, dried, and purified during the dosing process, not only can the chemicals be recycled and reused, but dust pollution can also be prevented. Therefore, we propose a dust removal device for waterworks chemical dosing rooms to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of easy diffusion, pollution, and moisture-induced caking of chemical dust in the dosing room of waterworks in the prior art.

[0005] The specific solution of this utility model is as follows:

[0006] Design a dust removal device for a water treatment plant's chemical dosing room, including a cyclone hood. Two symmetrically arranged main air inlet pipes are fixedly connected to the surface of the cyclone hood, and the two main air inlet pipes are connected to the cyclone hood. A dust suction pipe is fixedly connected to the other end of the main air inlet pipe on the left side, and a fixed ring frame is fixedly connected to the other end of the dust suction pipe. An axial flow fan is fixedly connected to the inner wall of the fixed ring frame, and a dust suction hood is fixedly connected to the lower end of the fixed ring frame. The dust suction hood is connected to the dust suction pipe and the main air inlet pipe. A nitrogen pipe is fixedly connected to the other end of the main air inlet pipe on the right side, and the nitrogen pipe is connected to the main air inlet pipe. A nitrogen pump is fixedly connected to the other end of the nitrogen pipe.

[0007] In a specific implementation, a secondary air intake pipe is fixedly connected to the surface of the main air intake pipe on the left side, and a hot air pipe is fixedly connected to the other end of the secondary air intake pipe. The hot air pipe is connected to the secondary air intake pipe and the main air intake pipe, and a hot air blower is fixedly connected to the other end of the hot air pipe.

[0008] In specific implementation, a cyclone separator is fixedly connected to the lower end of the cyclone shroud, and the cyclone separator is connected to the cyclone shroud. A plurality of symmetrically arranged deflecting plates are fixedly connected to the inner wall of the cyclone shroud. A cross-shaped fixing plate is fixedly connected to the lower end of the cross-shaped fixing plate, and a baffle cylinder is fixedly connected to the lower end of the cross-shaped fixing plate. The other end of the baffle cylinder extends to the discharge end of the cyclone separator.

[0009] In specific implementation, a gas collecting hood is fixedly connected to the upper end of the cyclone shroud, and an exhaust gas pipe is fixedly connected to the other end of the gas collecting hood. The gas collecting hood is connected to the cyclone shroud and the exhaust gas pipe. A filter box is fixedly connected to the other end of the exhaust gas pipe. An exhaust pipe is fixedly connected to the side wall of the filter box. The exhaust pipe is connected to the exhaust gas pipe and the filter box. The inlet end of the exhaust pipe and the outlet end of the exhaust pipe are symmetrically arranged and located above the outlet end of the exhaust gas pipe.

[0010] In practice, a tripod is fixedly connected to the side wall of the cyclone separator, and a recovery cylinder is provided below the discharge end of the cyclone separator.

[0011] In practice, the inner wall of the filter box is fixedly connected with multiple parallel filter plates, and the multiple filter plates are made of activated carbon material.

[0012] The beneficial effects of this utility model are as follows:

[0013] By placing the dust collection hood above the hopper, the diffusion of substances such as chemical dust, airborne dust, and harmful gases produced by the reaction can be controlled. The cyclone hood deflector can control the airflow speed and direction, improving separation efficiency. Compared with common methods such as baghouse dust collection, the use of cyclone separators is less prone to caking and clogging.

[0014] By using a hot air blower at the air inlet of the cyclone separator, not only can the moisture in the airflow be turned into water vapor for easy discharge, but the damp chemical dust can also be dried to prevent caking and clogging of the equipment. In addition, a nitrogen pump is installed at the air inlet of the cyclone separator to provide an inert environment for the cyclone separator, preventing static electricity generated by dust friction and collision during the separation process, which could lead to deflagration.

The feature is that by setting the hot air blower to blow hot air into the vortex shroud, the dust, water vapor and other impurities in the intake airflow are dried, and the caking and sticking phenomenon is prevented.

[0026] A cyclone separator 9 is fixedly connected to the lower end of the cyclone shroud 1. The cyclone separator 9 is connected to the cyclone shroud 1. A plurality of symmetrically arranged deflector plates 10 are fixedly connected to the inner wall of the cyclone shroud 1. A cross-shaped fixing plate 11 is fixedly connected to the lower end of the cross-shaped fixing plate 11. A baffle cylinder 12 is fixedly connected to the lower end of the cross-shaped fixing plate 11. The other end of the baffle cylinder 12 extends to the discharge end of the cyclone separator 9. The feature is that the airflow direction and velocity are adjusted by the deflector plates, and the baffle cylinder collides with the material dust during rotational separation, which can improve the separation efficiency.

[0027] A gas collecting hood 13 is fixedly connected to the upper end of the cyclone hood 1, and an exhaust gas pipe 14 is fixedly connected to the other end of the gas collecting hood 13. The gas collecting hood 13 is connected to the cyclone hood 1 and the exhaust gas pipe 14. A filter box 15 is fixedly connected to the other end of the exhaust gas pipe 14. An exhaust pipe 16 is fixedly connected to the side wall of the filter box 15. The exhaust pipe 16 is connected to the exhaust gas pipe 14 and the filter box 15.

The axial flow motor 4 sends the diffused drug dust, water vapor, air dust, and harmful gases produced by the reaction into the cyclone hood 1 through the dust collection pipe 5. At the same time, the hot air blower 8 pumps hot air into the cyclone hood 1 through the hot air pipe 7 to prevent the materials in the equipment from getting damp and caking. After the material airflow passes through the deflector plate 10 on the inner wall of the cyclone hood 1 to regulate the flow rate and direction, it rotates and enters the cyclone separator 9. Due to the different gravity and centrifugal force of different materials, the drug dust collides with the baffle cylinder 12 continuously during rotation, accelerating its fall into the recovery cylinder 20. Meanwhile, water vapor, dust, harmful gases, and other substances enter the exhaust pipe 14 through the gap of the cross-shaped fixing plate 11, are filtered by the filter plate 21 in the filter box 15, and are discharged into the exhaust pipe 16. During equipment operation, the nitrogen pump 18 on the other side of the cyclone hood 1 continuously pumps nitrogen through the nitrogen pipe 17 to prevent static electricity generated by the collision of powder during rotation, thus eliminating the risk of deflagration.
