Description

A split-type high-efficiency wet venturi dust collector Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a split-type high-efficiency wet venturi dust collector tower. Background Technology

[0002] Industrial production processes often generate waste gases containing high concentrations of dust, micron-sized particles, and corrosive gases (such as HCl and SO2). These waste gases not only pose serious threats to the environment and human health, but also place higher demands on the performance and durability of dust removal equipment.

[0003] Currently used dry dust collection equipment (such as bag filters and electrostatic precipitators) has good dust removal efficiency under normal operating conditions, but it is prone to problems such as equipment corrosion, filter bag clogging or failure when dealing with corrosive gases and high humidity exhaust gases, resulting in high maintenance costs and short service life. Traditional wet dust collection towers (such as spray towers and cyclone separators) have a certain ability to remove dust and acidic gases, but their removal efficiency for high-concentration dust or micron-sized fine particles is low, making it difficult to meet increasingly stringent emission standards. Furthermore, traditional wet dust collection equipment has a complex water tank structure, making sludge removal difficult and maintenance inconvenient, affecting the long-term stable operation of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a split-type high-efficiency wet venturi dust collector that can avoid the problem of low removal efficiency for high-concentration dust or micron-sized fine particles.

[0005] This utility model provides a split-type high-efficiency wet venturi dust collector, comprising:

[0006] The dust collector body and the water tank located at the lower end of the dust collector body, with a spray section provided on the top of the dust collector body;

[0007] The dust collector body includes a shrink tube, the spray section is installed at the upper end of the shrink tube, the lower end of the shrink tube is provided with a throat, the lower end of the throat is connected to an expansion tube, and the lower end of the expansion tube is connected to the upper end of the water tank through a flange.

[0008] Preferably, a ash removal port is provided at the lower end of one side of the water tank.

[0009] Preferably, a circulation pipe is provided in the middle of the water tank, and a bypass pipe is provided in the middle of the circulation pipe and connected to the water supply unit.

[0010] Preferably, the water tank is provided with partitions inside, and multiple partitions are arranged in an alternating manner, with a dustproof baffle provided on one side of the lower partition.

[0011] Preferably, the bottom of the water tank is provided with an inclined plate, and the lower end of the inclined plate is located on one side of the ash removal port.

[0012] Preferably, a filter cover is provided on the inner side of the circulation pipe, and the filter cover is installed on the inner side wall of the water tank by a bracket.

[0013] Preferably, one end of the dustproof baffle is installed in the side wall of the water tank via an installation shaft, and the other side of the dustproof baffle is provided with an overlapping plate, which is inclined.

[0014] Preferably, one end of the ash removal port is provided with a sewage discharge section, which includes a straight pipe for discharging bottom sludge and a liquid discharge pipe, both of which are connected to a discharge pump.

[0015] Preferably, a control valve is installed at the upper end of both the drain pipe and the straight pipe.

[0016] Preferably, an anti-clogging cover is embedded at the connection between the drain pipe and the straight pipe. The anti-clogging cover is fitted into a groove provided on one side of the pipe, and the drain pipe and the straight pipe are connected by a flange.

[0017] This utility model provides a split-type high-efficiency wet venturi dust collector. The internal spraying in the contraction section increases the gas velocity, and the high-speed airflow rapidly atomizes the sprayed washing liquid. At the throat, the gas and water come into full contact and reach saturation, breaking down the gas film adhering to the dust particles, causing the dust particles to be wetted and violently agglomerate. In the expansion tube, the airflow velocity decreases, the pressure rises, and the agglomeration is completed, forming larger dust-laden water droplets that are easier to capture. Under the action of gravity and centrifugation, the larger dust-laden droplets are captured by the water tank at the lower end, achieving the dust removal effect. It has high efficiency in removing high-concentration dust or micron-sized dust, has a simple structure, and facilitates water tank maintenance and cleaning. Attached Figure Description

[0033] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a split-type high-efficiency wet venturi dust collector.

[0034] As shown in Figures 1-8, this utility model embodiment provides a split-type high-efficiency wet venturi dust collector tower, including a dust collector body 200 for collecting the conveyed dust, and a water tank 100 located at the lower end of the dust collector body 200 for capturing dust-laden liquid droplets. The top of the dust collector body 200 is provided with a spray section 400 for spraying the internal dust.

[0035] The dust collector body 200 includes a shrink tube 210, and a spray section 400 is installed at the upper end of the shrink tube 210. The lower end of the shrink tube 210 is provided with a throat 220 to facilitate sufficient contact between gas and water. The lower end of the throat 220 is connected to an expansion tube 230 for collecting dust-laden water droplets. The lower end of the expansion tube 230 is connected to the upper end of the water tank 100 through a flange.

[0036] The internal spray of the contraction tube 210 increases the gas flow rate through the contraction section. The high-speed airflow rapidly atomizes the sprayed washing liquid. At the throat 220, the gas and water come into full contact and reach saturation. The gas film attached to the surface of the dust particles is broken, causing the dust particles to be wetted by water and undergo intense agglomeration. In the expansion tube 230, the airflow velocity decreases and the pressure rises, completing the agglomeration process and forming larger dust-laden water droplets, which are easier to capture. Under the action of gravity and centrifugation, the larger dust-laden water droplets are captured by the water tank 100 at the lower end, achieving the effect of dust removal. It has high efficiency in removing high-concentration dust or micron-sized dust, has a simple structure, and facilitates the maintenance and cleaning of the water tank 100.

[0037] A dust removal port 120 is provided on the lower side of the water tank 100 for centralized discharge of internal dust, which facilitates the discharge of dust-laden liquid deposited at the bottom of the water tank 100.

[0038] The water tank 100 is provided with a circulation pipe 110 in the middle for circulating the clarified water inside the lower end. A delivery pump is provided at the end of the circulation pipe 110 for transporting the liquid. A bypass pipe is provided in the middle of the circulation pipe 110 and is connected to the water supply unit. The bypass pipe can be connected to an external water supply unit for spraying through the spray unit 400 installed at the upper end, or the liquid inside the water tank 100 can be transported through the delivery pump at the lower end.

[0039] The water tank 100 is equipped with baffles 140 inside to facilitate the free settling of dust. The multiple baffles 140 are arranged in an alternating manner, which facilitates the rapid free settling of dust after it enters the water body. This can also cause the airflow to form vortex or rotating flow, which helps to increase the contact probability between particles and liquid, thereby improving dust removal efficiency.

[0040] The bottom of the water tank 100 is provided with an inclined plate 130 for collecting the bottom dust, which facilitates the later cleaning of the water tank 100. The lower end of the inclined plate 130 is located on one side of the dust removal port 120. The dust that settles at the lower end slides down the inclined plate 130 to the side of the dust removal port 120, which facilitates centralized cleaning.

[0041] A filter cover 111 is provided on the inner side of the circulation pipe 110. The filter cover 111 is installed on the inner side wall of the water tank 100 by a bracket. The mesh diameter of the filter cover 111 can be adjusted as needed to prevent internal dust from being sucked into the circulation pipe 110 and causing blockage.

[0042] A dust baffle 150 is provided on one side of the lower partition 140 to prevent dust from rising. One end of the dust baffle 150 is installed in the side wall of the water tank 100 via a mounting shaft and is connected to the output end of the drive motor. The other side of the dust baffle 150 is provided with an overlap plate 151 for overlapping with the partition 140. The overlap plate 151 is inclined. When in use, the dust baffle 150 is rotated open and when not in use, it is rotated closed, which can effectively prevent the dust-laden liquid droplets at the lower end from drying and rising upwards, thus avoiding repeated contamination of the equipment.

[0043] One end of the ash removal port 120 is provided with a sludge discharge section 300 for discharging internal impurities. The sludge discharge section 300 includes a straight pipe 320 for discharging bottom sludge and a drain pipe 330 for discharging upper liquid. Both the drain pipe 330 and the straight pipe 320 are connected to the discharge pump 310, which can classify and discharge impurities of different forms, effectively improving the stability and efficiency of equipment operation, facilitating maintenance and cleaning, and reducing the risk of equipment blockage.

[0044] Both the drain pipe 330 and the straight pipe 320 are equipped with control valves 340 at their upper ends for controlling the opening and closing of the pipes, which can be used to adjust the opening and closing of the pipes as needed.

[0045] An anti-clogging cover 331 is embedded at the connection between the drain pipe 330 and the straight pipe 320. The anti-clogging cover 331 is fitted into the groove set on one side of the pipe, and the drain pipe 330 and the straight pipe 320 are connected by a flange to prevent sludge from accumulating and entering the inlet of the drain pipe 330, thus protecting the drain pipe 330 and preventing it from becoming clogged.

[0046] The water tank 100 and the dust collector body 200 are made of FRP material, which has excellent corrosion resistance and can be used in acidic, alkaline or organic waste gas environments.

[0047] The working principle of a split-type high-efficiency wet venturi dust collector: spraying inside the contraction tube 210 increases the gas flow rate through the contraction section. The high-speed airflow rapidly atomizes the sprayed washing liquid. At the throat 220, the gas and water come into full contact and reach saturation. The gas film attached to the surface of the dust particles is broken, causing the dust particles to be wetted by water and undergo intense agglomeration. In the expansion tube 230, the airflow velocity decreases and the pressure rises, completing the agglomeration process and forming larger dust-laden water droplets, which are easier to capture. Under the action of gravity and centrifugation, the larger dust-laden water droplets are captured by the water tank 100 at the lower end, achieving the effect of dust removal. It has high efficiency in removing high-concentration dust or micron-sized dust, has a simple structure, and facilitates the maintenance and cleaning of the water tank 100.

[0048] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
