Description

Technical Field

[0001] The present application relates to the field of waste gas treatment, and in particular to a hazardous waste storage waste gas treatment tower. Background Art

[0002] Hazardous waste storage waste gas treatment towers are used to treat waste gases generated during hazardous waste storage. These gases may contain a variety of harmful components, including volatile organic compounds (VOCs), acidic gases, and malodorous gases, posing a threat to the environment and human health. The design and operation of these treatment towers are designed to reduce the emission of these pollutants and ensure that the waste gases meet environmental standards before discharge.

[0003] The waste gas treatment tower removes harmful components from the gas by spraying liquid in contact with the gas and absorbing it with fillers. In the treatment tower, the gas containing dust or pollutants enters from the bottom of the tower, flows upward, and filters the waste gas through the filler absorption layer. The spraying system sprays liquid downward to form fine droplets. The contact between the gas and the droplets promotes the absorption or neutralization reaction of the pollutants. The treated gas is finally discharged from the top of the tower to achieve the purpose of purification.

[0004] However, in the process of implementing the relevant technical solutions, it was found that there are at least the following technical problems: the exhaust gas pipe for transporting exhaust gas is connected to the bottom of the treatment tower. In order to make the exhaust gas entering the bottom of the treatment tower as evenly dispersed as possible and ensure that the exhaust gas can evenly contact the upper filler absorption layer and the sprayed mist water, a fan will be installed at the bottom of the treatment tower to blow away the exhaust gas entering the treatment tower. The use of the fan will also cause noise, and the fan will also increase the speed of the airflow, reducing the residence time of the exhaust gas in the filler absorption layer, which is not conducive to improving the noise reduction requirements and purification effect of the exhaust gas treatment tower. Summary of the Invention

[0005] This application solves the technical problem of noise generation in the prior art by using a fan to blow away the exhaust gas entering the bottom of the treatment tower by providing a hazardous waste storage exhaust gas treatment tower. It realizes the use of non-electrified airflow pipes and their own physical properties to achieve exhaust gas diffusion and speed reduction, thereby improving the noise reduction and purification effects of the exhaust gas treatment tower.

[0006] The present application provides a hazardous waste storage waste gas treatment tower, comprising a tower body, an air inlet pipe connected to the bottom of the tower body, a filler absorption layer located above the air inlet pipe, an injection head located above the filler absorption layer, and an air outlet pipe connected to the top of the tower body, wherein the air inlet pipe is located at one end of the inner cavity of the tower body and is provided with an air dispersion component; the air dispersion component comprises: an end cap fixed to the end of the air inlet pipe located at one end of the inner cavity of the tower body; a plurality of air dispersion pipes are provided and all are fixed on the end cap, the air dispersion pipes are connected to the air inlet pipe, and ... An intermediate channel is provided in the pipe, which runs through the end faces of both ends of the diffuser pipe. Side flow grooves are provided on the side walls of the intermediate channel. The end of the side flow groove closer to the end cover is the inflow end, and the end farther from the end cover is the outflow end. There is an obtuse angle between the inflow end and the intermediate channel, and an acute angle between the outflow end and the intermediate channel. A partition block is fixed in the side flow groove, and there is a distance between the partition block and the groove wall of the side flow groove. Several side flow grooves are provided on both side walls parallel to each other in the intermediate channel, and are staggered.

[0007] Furthermore, the air diffusion pipe includes a fixed section and a folding section, the fixed section is fixed on the end cover, and the folding section and the fixed section are hingedly connected via a hinge.

[0008] Furthermore, a magnet is fixedly connected to the fixed section, and the magnet is used to adsorb the fixed section onto the folding section.

[0009] Furthermore, a plurality of the air diffusion pipes are evenly arranged around the end cover in multiple circles, the diameter of each circle is gradually shortened, and the air diffusion pipes in any circle are located between two air diffusion pipes in two adjacent circles.

[0010] Furthermore, a side surface of the partition block facing the side flow groove and a concave surface of the side flow groove are equidistant curved surfaces.

[0011] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0012] Due to the use of a diffuser pipe, when the exhaust gas passes through the middle channel in the diffuser pipe, since there is an obtuse angle between the inflow end and the middle channel, the exhaust gas can enter the side flow groove without any resistance and finally reach the outflow end. Since there is an acute angle between the outflow end and the middle channel, the exhaust gas at the outflow end will hit the exhaust gas in the middle channel in the opposite direction, and finally form a vortex between the outflow end and the middle channel, slowing down the flow rate of the exhaust gas in the middle channel. The exhaust gas can have more time to diffuse at the bottom of the tower to ensure that the exhaust gas can contact the filler absorption layer with a larger area, realizing the use of non-electrified airflow pipes and their own physical properties to achieve exhaust gas diffusion and deceleration, thereby improving the noise reduction and purification effects of the exhaust gas treatment tower.

[0019] In order to better understand the technical solution of the present application, the technical solution of the present application will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1 , a hazardous waste storage waste gas treatment tower includes a tower body 1, an air inlet pipe 2, a filler absorption layer 3, an injection head 4, an air outlet pipe 5 and a gas dispersion component 6. The air inlet pipe 2 is connected to the bottom of the tower body 1, and the air inlet pipe 2 can be used to pass the waste gas into the bottom of the tower body 1; multiple layers of filler absorption layers 3 are arranged in the tower body 1, and are all located above the air inlet pipe 2. The filler absorption layer 3 can include Raschig rings, Pall rings, saddle-shaped and corrugated fillers, etc. The filler absorption layer 3 can provide a huge surface area for increasing the contact opportunity between gas and liquid. A injection head 4 is arranged above each layer of filler absorption layer 3. The injection head 4 can be installed on the inner wall of the tower body 1 through a mounting bracket. The injection head 4 is responsible for evenly spraying the absorption liquid onto the filler layer so that the liquid film can evenly cover the filler surface to improve the absorption efficiency.

[0021] Reference Figure 1 、 Figure 2 as well as Figure 3The air diffusion assembly 6 comprises an end cap 61 and an air diffusion pipe 62. The end cap 61 covers the end of the air intake pipe 2 located within the tower body 1. The end of the air intake pipe 2 located within the tower body 1 is vertically upward, and the end cap 61 is fixedly connected to the air intake pipe 2. The air diffusion pipe 62 is strip-shaped with a rectangular cross-section. There are multiple air diffusion pipes 62, each fixed to the end cap 61. The air diffusion pipes 62 are evenly arranged around the end cap 61, forming multiple circles with gradually decreasing diameters. The air diffusion pipes 62 in any circle are located between the two air diffusion pipes 62 in the adjacent circles. The air diffusion pipes 62 are connected to the air intake pipe 2. The air diffusion tube 62 includes a fixed section 6201, a folding section 6202, a hinge 6203 and a magnet 6204. The fixed section 6201 is fixed to the end cover 61. The folding section 6202 and the fixed section 6201 are hingedly connected by the hinge 6203. The magnet 6204 is fixed to the fixed section 6201 and is used to attract the fixed section 6201 to the folding section 6202.

[0022] Reference Figure 4 and Figure 5 As described above, an intermediate channel 621 is provided in the diffuser pipe 62, which passes through the end faces of both ends of the diffuser pipe 62. The cross section of the intermediate channel 621 is rectangular, and side flow grooves 622 are provided on the four side walls of the intermediate channel 621. The end of the side flow groove 622 closer to the end cover 61 is the inflow end 6221, and the end farther from the end cover 61 is the outflow end 6222. There is an obtuse angle between the inflow end 6221 and the intermediate channel 621, so that the exhaust gas can enter the side flow groove 622 without any resistance. There is an acute angle between the outflow end 6222 and the intermediate channel 621. The exhaust gas at the outflow end 6222 will collide with the exhaust gas in the middle channel 621 in the opposite direction, and eventually form a vortex between the outflow end 6222 and the middle channel 621, slowing down the flow rate of the exhaust gas in the middle channel 621. A partition block 623 is fixed in the side flow groove 622. There is a distance between the partition block 623 and the groove wall of the side flow groove 622. The side surface of the partition block 623 facing the side flow groove 622 and the concave surface of the side flow groove 622 are equidistant curved surfaces. The side flow grooves 622 on the two parallel side walls of the middle channel 621 are staggered.

[0023] This application can explain its functional principles through the following operation methods:

[0024] The exhaust gas in the intake pipe 2 will enter the diffuser pipe 62. When the exhaust gas passes through the middle channel 621 in the diffuser pipe 62, part of the exhaust gas will enter the side flow groove 622 from the inlet end 6221. Since there is an obtuse angle between the inlet end 6221 and the middle channel 621, the exhaust gas can enter the side flow groove 622 without any resistance. Then, the exhaust gas flows in the side flow groove 622 and finally reaches the outflow end 6222. Since there is an acute angle between the outflow end 6222 and the middle channel 621, the exhaust gas at the outflow end 6222 will collide with the exhaust gas in the middle channel 621 in the opposite direction, and finally form a vortex between the outflow end 6222 and the middle channel 621, slowing down the flow rate of the exhaust gas in the middle channel 621. Under the effect of multi-stage deceleration, the flow rate of the exhaust gas flowing out of the diffuser pipe 62 will gradually decrease, so that it can have more time to diffuse at the bottom of the tower, so as to ensure that the exhaust gas can contact the filler absorption layer 3 with a larger area.

[0025] When there is no need to release the exhaust gas at a slower speed, the foldable section 6202 can be folded and adsorbed to the fixed section 6201 using the magnet 6204, thereby shortening the length of the diffusion tube 62. Compared with a longer diffusion tube 62, the speed of releasing the exhaust gas can be increased by using only the fixed section 6201.

[0026] The diffuser pipe 62 does not have any electrical equipment and requires no maintenance. It uses its own physical properties to diffuse and reduce the speed of the exhaust gas, realizing the use of non-electrified airflow pipes, solving the technical problem of using fans to blow away the exhaust gas entering the bottom of the treatment tower in the existing technology, causing noise, and improving the noise reduction and purification effects of the exhaust gas treatment tower.

[0027] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.

[0028] The above is only a preferred specific implementation method of the embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
