Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to an explosion-proof activated carbon waste gas treatment box. Background Art

[0002] Dust explosion is the phenomenon that the dust particles suspended in the air fully contact with the oxygen in the air and the oxidation reaction is completed instantly under specific conditions, releasing a large amount of heat in the reaction, thereby generating high temperature and high pressure. Some existing waste gas treatment boxes usually adopt the method of controlling dust concentration to prevent explosion.

[0003] In the Chinese patent with the publication number CN 219441178 U, the utility model uses a setting method in which a clamp block, a compression spring, a connecting rod, a limit block and a connecting block are matched to control the fixation of the activated carbon adsorption layer through the clamp block, so that after the use period of the activated carbon adsorption layer ends, it is easy to remove the activated carbon adsorption layer and replace the activated carbon layer;

[0004] The above-mentioned device stores activated carbon through the outer frame, but it is inconvenient to replace the activated carbon in the inner activated carbon layer. When the activated carbon layer is filled with activated carbon, in order to ensure the adsorption force and reduce the gaps between the activated carbon particles, in order to squeeze the activated carbon inside, part of the activated carbon will be stuck together with the edges of the holes on the frame. When the activated carbon is replaced, this part of the activated carbon is not convenient to remove. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 6 An explosion-proof activated carbon waste gas treatment box includes a waste gas treatment box 1, an activated carbon adsorbent 2, and a dust concentration regulating device 3. Gas containing dust flows in the waste gas treatment box 1, and the dust concentration regulating device 3 can send external gas into the waste gas treatment box 1, thereby reducing the dust content in the waste gas, thereby preventing the dust-doped gas from reaching the explosion threshold;

[0031] A plurality of activated carbon adsorbents 2 are distributed in parallel inside the exhaust gas treatment box 1. The activated carbon adsorbents 2 are filled with activated carbon, which can adsorb particles in the dust-containing exhaust gas and reduce the solid particle content therein;

[0032] like Figure 2 , Figure 6 As shown, the activated carbon adsorbent 2 includes an inner frame 201 and an outer plate 202. The inner frame 201 and the outer plate 202 are both provided with a plurality of through holes for exhaust gas circulation. The size of the through holes needs to be smaller than the size of the activated carbon to prevent the activated carbon from being squeezed out from the through holes. The exhaust gas enters the adsorption chamber surrounded by the inner frame 201 and the outer plate 202 through the through holes, and continues to move after being adsorbed by the activated carbon therein.

[0033] In a further embodiment, the adsorption capacity of the activated carbon is limited and needs to be replaced regularly. In order to facilitate the replacement of the activated carbon, the inner frame 201 is slidably connected to the outer plate 202. Specifically, a slider 204 is fixedly installed on the outer plate 202. The slider 204 is set in a convex shape, and the length away from the end of the outer plate 202 is greater than the length close to the outer plate 202. The convex-shaped slider 204 is completely inserted into the slide groove in the inner frame 201 and will not fall out of the slide groove, thereby preventing the outer plate 202 from being completely separated from the inner frame 201. In this way, it is more convenient to close and separate the two. Two sliders 204 are provided, and the two sliders 204 are respectively installed at the upper and lower ends of the outer plate 202;

[0034] The inner frame 201 is slidably connected to the outer plate 202. When the two are closed to form a sealed adsorption chamber, it is necessary to fix the position between the outer plate 202 and the inner frame 201 to prevent the two from separating and the activated carbon in the adsorption chamber from falling. Therefore, an outer plate positioning mechanism 203 is provided in the inner frame 201. The outer plate positioning mechanism 203 includes an outer plate positioning plate 2031. The outer plate positioning plate 2031 is slidably connected to the mounting groove in the inner frame 201. A compression spring 2032 is installed between the outer plate positioning plate 2031 and the inner wall of the mounting groove. The compression spring 2032 The outer plate positioning plate 2031 can be squeezed to move it to one side of the outer plate 202. The outer plate positioning plate 2031 is slidably connected to the inner wall of the outer plate positioning groove 2033 in the inner frame 201. A card slot that matches the outer plate positioning plate 2031 is provided in the outer plate 202. The outer plate positioning mechanism 203 is provided on the side of the inner frame 201 close to the fixed plate. The size of the adsorption hole in the exhaust gas treatment box 1 is the same as the size of the inner frame 201 and the outer plate 202, but smaller than the size of the fixed plate. The fixed plate can block the adsorption hole. A handle is installed at one end of the fixed plate away from the exhaust gas treatment box 1;

[0035] The activated carbon adsorbent 2 is plugged into the adsorption hole in the exhaust gas treatment box 1. In order to fix the position of the activated carbon adsorbent 2 after it is inserted into the adsorption hole, an adsorbent positioning mechanism 101 is required to be provided at the position of the adsorption hole corresponding to the exhaust gas treatment box 1. Each activated carbon adsorbent 2 is provided with two adsorbent positioning mechanisms 101 respectively located on the upper and lower sides thereof. The adsorbent positioning mechanism 101 includes an adsorbent positioning plate 1011. A square groove is provided on the side of the adsorbent positioning plate 1011 close to the exhaust gas treatment box 1. The square groove is engaged with the activated carbon adsorbent 2. A slope shape is provided on the side of the adsorbent positioning plate 1011 away from the square groove. The adsorbent positioning plate 1011 is inserted into the positioning tube. An elastic component is installed in the positioning tube. The elastic component can provide a force to move the adsorbent positioning plate 1011 toward the side of the activated carbon adsorbent 2. The adsorbent positioning plate 1011 is slidably connected with the adsorbent positioning groove 1012 in the positioning tube.

[0036] In order to ensure the adsorption efficiency, the activated carbon needs to be squeezed and placed inside the inner frame 201. Part of the activated carbon will be squeezed at the edge of the through hole in the inner frame 201. When the activated carbon is replaced, this part of the activated carbon is not easy to fall off. Therefore, a wedge block is installed in the inner frame 201. The wedge block is fixedly connected to the inclined plate 205, and the inclined plate 205 is obliquely arranged inside the inner frame 201. The wedge block is slidably connected to the guide groove 206.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
