Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas water film dust removal device. Background Technology

[0002] In industrial production processes, such as chemical, metallurgical, and building materials industries, a large amount of waste gas is generated. This waste gas often contains a large amount of solid impurities, such as dust and particulate matter. If this waste gas is discharged directly into the atmosphere without effective treatment, it will cause serious pollution to the environment and endanger human health.

[0003] Currently, although there are some exhaust gas dust removal devices on the market, they have many shortcomings. For example, some devices have low dust removal efficiency and cannot effectively remove tiny particles in exhaust gas; some devices are also prone to blockage during operation, which affects the normal operation and service life of the equipment.

[0004] Therefore, a waste gas water film dust removal device is proposed here to solve the above-mentioned problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problem that some existing devices have low dust removal efficiency and cannot effectively remove tiny particles in exhaust gas, this utility model provides an exhaust gas water film dust removal device.

[0006] This utility model is achieved using the following technical solution:

[0007] A waste gas water film dust removal device includes a dust removal box, a top cover on the top of the dust removal box, a fan on the upper surface of the top cover, a hole on the top cover for the fan input end to communicate with, an air inlet pipe on the side of the dust removal box, the air inlet pipe extending into the interior of the dust removal box and arranged horizontally, and a plurality of air outlet holes evenly provided on the upper surface of the part of the air inlet pipe located inside the dust removal box.

[0008] The dust collection box is also equipped with a water film dust removal device, which is used to remove solid impurities from the exhaust gas.

[0009] The water film dust removal equipment includes a water storage ring, which is hollow inside and connected to an external water tank through a pipe. The water storage ring is fixed to the inner wall of the dust removal box. The water storage ring is provided with two sets of spray heads, and each set of spray heads has multiple spray heads, which are symmetrically fixed on the left and right sides of the water storage ring.

[0010] The dust collector has two symmetrical sliding grooves on its inner two side walls, and the water storage ring has symmetrical sliders on its two side walls. The sliders are fixedly connected to the water storage ring and are located inside the sliding grooves, where they can move up and down.

[0011] The water storage ring is symmetrically provided with lifting rings on both the front and rear sides.

[0012] The dust collector is equipped with a filter screen inside, which is located above the air inlet pipe and fixed to the inner wall of the dust collector. The dust collector is equipped with a drain port on the side wall, which is located at the bottom side of the dust collector and below the filter screen.

[0013] The present invention has the following advantages over the prior art:

[0014] 1. By installing a water film dust removal device inside the dust removal box and using the uniform air outlet design of the air inlet pipe, the exhaust gas is evenly dispersed in the dust removal box. Combined with the water film formed by the water film dust removal device, it can effectively adsorb solid impurities in the exhaust gas, greatly improving the dust removal efficiency.

[0015] 2. A filter screen is installed below the air inlet pipe, and a drain port is installed on the side wall of the filter box. The filter screen performs preliminary filtration of the exhaust gas, reducing the risk of large particulate impurities clogging the water film dust removal equipment, ensuring the stable operation of the device. Solid impurities intercepted by the filter screen and water containing solid impurities flowing down with the water film will accumulate at the bottom of the dust removal box. These contaminants can be easily discharged through the drain port, ensuring the normal operation of the dust removal device. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a waste gas water film dust removal device includes a dust collection box 1. The top of the dust collection box 1 is provided with a top cover 5. A fan 6 is provided on the upper surface of the top cover 5. The top cover 5 is provided with a hole for the input end of the fan 6 to be connected. An air inlet pipe 2 is provided on the side of the dust collection box 1. The air inlet pipe 2 extends into the interior of the dust collection box 1 and is arranged horizontally. The upper surface of the part of the air inlet pipe 2 located inside the dust collection box 1 is evenly provided with multiple air outlets 21. Waste gas enters the dust collection box 1 through the air inlet pipe 2 and is evenly sprayed out from the multiple air outlets 21, so that the waste gas is evenly dispersed in the dust collection box 1, which is beneficial to subsequent dust removal treatment.

[0025] The dust collection box 1 is also equipped with a water film dust removal device, which is used to remove solid impurities from the exhaust gas.

[0026] The water film dust removal device includes a water storage ring 4, which is hollow inside and connected to an external water tank via a pipe. Water from the external water tank can be continuously supplied to the water storage ring 4, providing a sufficient water source for water film dust removal. The water storage ring 4 is fixed to the inner wall of the dust removal box 1. Two sets of spray heads 41 are provided on the water storage ring 4, with multiple spray heads 41 in each set, symmetrically fixed on the left and right sides of the water storage ring 4. Water is sprayed from the spray heads 41, forming a uniform water film inside the dust removal box 1. When solid impurities in the exhaust gas come into contact with the water film, they are adsorbed by the water film and flow down with the water, thereby achieving the removal of solid impurities from the exhaust gas.

[0027] To facilitate the installation, maintenance, and position adjustment of the water storage ring 4, two symmetrical sliding grooves 13 are provided on the inner two side walls of the dust collector 1. Slider blocks are symmetrically provided on the two side walls of the water storage ring 4. The sliders are fixedly connected to the water storage ring 4 and are located inside the sliding grooves 13, allowing them to move up and down within the grooves 13. Through the cooperation of the sliders and sliding grooves 13, the water storage ring 4 can be easily installed into the dust collector 1, and its height can be easily adjusted when needed.

[0028] Lifting rings 42 are symmetrically provided on the front and rear sides of the water storage ring 4. The lifting rings 42 facilitate the lifting operation of the water storage ring 4 using lifting equipment, further simplifying the installation and maintenance of the water storage ring 4.

[0029] The dust collector 1 is equipped with a filter screen 3, which is located above the air inlet pipe 2 and fixed to the inner wall of the dust collector 1. A drain port 11 is located on the side wall of the dust collector 1, at the bottom of the side, below the filter screen 3. The filter screen 3 can perform preliminary filtration of the exhaust gas, intercepting larger solid particles and reducing the burden on subsequent water film dust removal. Solid impurities intercepted by the filter screen 3, as well as water containing solid impurities flowing down with the water film, accumulate at the bottom of the dust collector 1. These contaminants can be easily discharged through the drain port 11, ensuring the normal operation of the dust removal device.

[0030] The working principle of this utility model is as follows: When in use, turn on the water pump of the external water tank to deliver water to the water storage ring 4. The water is sprayed out from the spray head 41 and forms a uniform water film in the dust removal box 1. Start the fan 6 so that the exhaust gas enters the dust removal box 1 through the air inlet pipe 2 and is sprayed out evenly from the air outlet 21 on the air inlet pipe 2. The solid impurities in the exhaust gas are adsorbed after contacting the water film and flow down with the water.

[0031] Filter 3 performs preliminary filtration of exhaust gas, intercepting larger solid particles and further purifying the exhaust gas. Water and dirt containing solid impurities that accumulate at the bottom of dust collector 1 are periodically discharged through drain outlet 11.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
