Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device. Background Art

[0002] Waste gas treatment mainly deals with various industrial waste gases generated in the industrial environment, such as dust particles, smoke, odorous gases and toxic and harmful gases. For example, factory smoke waste gas, workshop dust waste gas, organic waste gas, waste gas odor, acid and alkali waste gas and chemical waste gas are purified to meet the waste gas emission standards;

[0003] Taking the treatment of VOCs waste gas as an example, it includes thermal destruction method, adsorption method, biological treatment method, pressure swing adsorption separation and purification technology, oxidation method, liquid absorption method and condensation recovery method; among them, the adsorption method can treat low-concentration, high-flux organic waste gas, especially the use of adsorbent products to adsorb VOCs waste gas, which requires less energy consumption and has a higher purification efficiency for organic waste gas;

[0004] However, after using the adsorbent product for a period of time, the void structure inside the adsorbent is saturated and needs to be replaced. During the process of replacing the adsorbent inside the equipment, the equipment needs to be stopped, which will affect the normal production process of the factory.

[0005] For example, the existing adsorption-type exhaust gas treatment equipment with application number CN202223098351.X discloses a solution of a limit assembly that can be quickly snapped together and disassembled, so that the shell components located on the side can be removed to increase the maintenance operation area, thereby replacing the internal filter materials and other components; however, the above technical solution also requires the equipment to stop running during the process of replacing the adsorbent inside the equipment, affecting the normal production process of the factory.

[0041] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, an embodiment of the waste gas treatment device provided by the utility model is described, which ensures the normal and continuous operation of the waste gas treatment device and reduces the impact on the factory production process during the replacement and maintenance of the adsorbent material inside the device:

[0042] The main part of the exhaust gas treatment device is composed of an operating cabin 11 and a waste filter cabin 12 , in which a filter material 22 for filtering exhaust gas is installed.

[0043] The filter material 22 in the waste filter chamber 12 is divided into two upper and lower parts by the air-permeable baffle, the partition 24 and the positioning partition 41 , and a lifting gate 31 is vertically slidably mounted on the side of the positioning partition 41 .

[0044] The lifting gate plate 31 is provided with an exhaust channel I 32 and an exhaust channel II 33 , and the positioning partition plate 41 is provided with an access channel I 43 and an access channel II 44 that can communicate with the filter material 22 divided into two upper and lower parts.

[0045] By manually adjusting the vertical relative position of the lifting gate plate 31 and the positioning partition plate 41, the exhaust channel I 32 is switched to be connected with the access channel I 43 or the exhaust channel II 33 is switched to be connected with the access channel II 44;

[0046] When the exhaust channel I 32 is connected to the access channel I 43 , the exhaust gas is filtered only by the filter material 22 located at the upper portion.

[0047] When the exhaust channel II 33 is connected to the access channel II 44 , the exhaust gas is filtered only by the filter material 22 located at the lower part.

[0048] By switching the two parts of the filter material 22 for separate use, the filter material 22 that needs to be replaced can be disassembled and replaced, and at the same time, the other part of the filter material 22 can still filter and process the exhaust gas, thereby ensuring the normal and continuous operation of the exhaust gas treatment device during the replacement and maintenance of the adsorbent material inside the equipment, thereby reducing the impact on the factory production process.

[0049] Reference Figure 5 , Figure 6 and Figure 7 As shown, an embodiment of the waste gas treatment device provided by the utility model is described, which switches the working state of the two parts of the filter material 22 in the waste filter chamber 12:

[0050] like Figure 5 As shown, when the lift gate 31 is raised to the top, the exhaust channel I 32 and the access channel I 43 are connected. At this time, only the filter material 22 located at the upper part of the waste filter chamber 12 is in the working state;

[0051] Then manually rotate the control handle 13 to drive the lifting gate 31 to move downward. Figure 6 As shown, the exhaust channel I 32 and the access channel I 43 are isolated, and the exhaust channel II 33 begins to communicate with the access channel II 44 until Figure 7 As shown, the exhaust channel II 33 is completely connected with the access channel II 44. At this time, only the filter material 22 located at the lower part of the waste filter chamber 12 is in working condition.

[0052] Reference Figure 1 and Figure 2 As shown, an embodiment of the exhaust gas treatment device provided by the utility model is described, in which the vertical relative positions of the lifting gate plate 31 and the positioning partition plate 41 are adjusted manually:

[0053] A plurality of racks 34 are fixedly mounted on the lifting gate plate 31, and a control handle 13 is rotatably mounted in the operating cabin 11. A plurality of gears 14 corresponding to the number and position of the plurality of racks 34 are fixedly mounted on the control handle 13. The gears 14 are connected to each other through meshing transmission. The control handle 13 is manually rotated to realize manual adjustment of the vertical relative position between the lifting gate plate 31 and the positioning partition 41, and switch the exhaust channel I 32 to be connected to the access channel I 43 or the exhaust channel II 33 to be connected to the access channel II 44.

[0054] Reference Figure 2 and Figure 3 As shown, the waste gas treatment device provided by the utility model is described, the filter material 22 is installed in the waste filter chamber 12 through the filter material receiving box 21, and the filter material 22 in the waste filter chamber 12 is replaced by replacing the filter material receiving box 21:

[0055] The filter material 22 is installed in the waste filter chamber 12 through a filter material containing box 21. The filter material containing box 21 is installed in the waste filter chamber 12 by horizontal sliding. Multiple ventilation holes 23 are respectively arranged on both sides of the filter material containing box 21. There is only one filter material containing box 21 located on the upper side of the partition 24, and there are multiple filter material containing boxes 21 located on the lower side of the partition 24. The multiple filter material containing boxes 21 are stacked and arranged.

[0056] In this application, Figure 2 In the process, the filter material container box 21 located on the upper side of the partition 24 is only used during the replacement operation of the filter material container box 21 located on the lower side of the partition 24, which plays a role of transition and connection, ensures the normal and continuous operation of the exhaust gas treatment device, and reduces the impact on the factory production process. After the filter material container box 21 located on the lower side of the partition 24 is replaced, the filter material container box 21 located on the upper side of the partition 24 is reused for exhaust gas purification treatment operations.

[0057] On the basis of the above-mentioned embodiment, the filter material 22 divided into the upper and lower parts respectively uses one or more of silica gel, alumina, activated carbon, zeolite molecular sieve, carbon molecular sieve and polyacrylamide; the filter material containing box 21 located on the upper and lower sides of the partition 24 is provided with equal amounts of filter materials 22 of different types, so as to carry out targeted adsorption and purification treatment according to the types of waste gas generated by different processes in factories and dust-free workshops.

[0060] A groove 42 is provided in the middle of one side where the positioning partition 41 abuts against the filter material holding box 21. After the exhaust gas enters the groove from the access channel I 43 or the access channel II 44, it enters the filter material 22 through the vent hole 23 at the end of the filter material holding box 21, thereby reducing the influence of the size problem of the access channel I 43 and the access channel II 44 on the uniformity of the flow of the exhaust gas in the access filter material 22.

[0061] Reference Figure 2 and Figure 3 As shown, an embodiment of the exhaust gas treatment device provided by the utility model is described, which increases the stability of the lifting gate 31 during the lifting process in the operating cabin 11 to ensure the normal operation of the equipment:

[0062] Limiting grooves are respectively arranged on both sides of the lifting gate plate 31 , and the limiting grooves on both sides are respectively engaged and slidably connected with the limiting rails 15 fixedly installed at both ends of the operating cabin 11 .

[0063] Among them, the limiting track 15 plays a guiding and positioning role, so that the gear 14 and the rack 34 can always maintain a meshing state, and the lifting gate 31 and the positioning partition 41 can always fit together, avoiding exhaust gas leakage from the gap between the lifting gate 31 and the positioning partition 41, thereby increasing the production safety and environmental protection of factories and dust-free workshops.

[0064] Furthermore, an upper sealing plate 16 and a lower sealing plate 17 are fixedly installed at the upper and lower ends of the operating cabin 11 , respectively. The upper sealing plate 16 and the lower sealing plate 17 are plug-in and slidably connected to the upper and lower sides of the lifting gate plate 31 , respectively.

[0066] Furthermore, a lubricating layer is provided on the outer surfaces of the upper sealing plate 16 and the lower sealing plate 17 to improve the smoothness and stability of the lifting gate plate 31 during the lifting and lowering process in the operating cabin 11 .

[0067] The lubricating layer is achieved by applying lubricating oil or grease.

[0068] Reference Figure 2 and Figure 3 As shown, an embodiment of the waste gas treatment device provided by the utility model is described, in which the installation state of the filter material 22 in the filter material containing box 21 is improved to increase the purification efficiency of the waste gas:

[0069] The filter material 22 is composed of a plurality of overlapping sheet-like filter materials, wherein the sheet-like filter material is obtained by packaging an adsorbent in a breathable package such as non-woven fabric and then extruding it into a flat square.

[0070] The types and qualities of the adsorbent materials in the plurality of sheet filter materials can be set to be the same or different. The types of materials can be selected from silica gel, alumina, activated carbon, zeolite molecular sieve, carbon molecular sieve and polyacrylamide, thereby improving the efficiency of the equipment in purifying and adsorbing the waste gas generated in factories and dust-free workshops.
