Description

Technical Field

[0001] The utility model belongs to the technical field of activated carbon gas adsorption devices, in particular to a VOCS activated carbon gas adsorption bed in an environment. Background Art

[0002] Activated carbon adsorption beds, also known as activated carbon adsorption boxes, are an important type of industrial waste gas treatment equipment. They utilize the powerful adsorption capacity of activated carbon to treat pollutants in the air. They are primarily used to treat volatile organic compounds (VOCs), odors, and harmful gases. These pollutants are captured and retained by the activated carbon's microporous structure, thereby purifying the air. During operation, pollutant-laden waste gas, powered by a blower, enters the activated carbon adsorption box through negative or positive pressure. When the waste gas passes through the activated carbon layer, the molecular attraction or chemical bond forces in the activated carbon's microporous structure attract the harmful molecules in the waste gas, causing them to concentrate and remain on the solid surface of the activated carbon, thereby achieving the effect of removing pollutants.

[0003] However, when the existing activated carbon adsorption equipment is in use, the air passages in the equipment box are too open, resulting in some of the harmful gases being unable to come into contact with the activated carbon when entering the box, resulting in reduced filtering effect.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] Example 1: Reference Figure 1-Figure 7A VOCS activated carbon gas adsorption bed in an environment includes a shell 1, and further includes: a first filter area 12 and a second filter area 13 are provided in the shell 1, the first filter area 12 is used to adsorb particulate matter; a first air duct 3, a second air duct 4, and a third air duct 5 are formed in the shell 1; two rows and two columns of drawer pull boxes 15 are provided in the second filter area 13, and a rotating shaft 16 is provided above each drawer pull box 15 in the first row, which is rotated by a first torsion spring 165, and a first dial plate 161 is fixedly connected to the rotating shaft 16; a second dial plate 171 connected to the shell 1 is rotated by a second torsion spring, and the second The dial plate 171 is located above each drawer pull box 15 in the second row; the first air duct 3 is located between the drawer pull box 15 and the top of the housing 1, the second air duct 4 is located between the first and second rows of drawer pull boxes 15, and the third air duct 5 is located between two adjacent drawer pull boxes 15 in the first row; a windshield 17 is fixedly connected to the housing 1 between the first and second rows of drawer pull boxes 15, and the second dial plate 171 is rotatably connected to the windshield 17. A first blocking plate 2 is fixedly connected between the second row of drawer pull boxes 15 and the bottom of the housing 1, and a second blocking plate 21 is fixedly connected between adjacent drawer pull boxes 15 in the second row;

[0025] An air inlet 11 and an air outlet 14 are respectively provided on both sides of the housing 1. A pre-filter cotton 122 is slidably provided in the first filter area 12 of the housing 1 to absorb particulate matter.

[0026] The second filter area 13 is symmetrically fixedly connected to a vertical plate 131, and a support strip 132 is fixedly connected to the vertical plate 131. The drawer pull box 15 is placed on the support strip 132;

[0027] A first limiting block 167 and a second limiting block 172 are fixedly connected to one side of the first shift plate 161 and the second shift plate 171 on the housing 1. The first limiting block 167 and the second limiting block 172 are used to limit the rotating first shift plate 161 and the second shift plate 171.

[0028] When the device is in use, the external pipe is connected to the air inlet 11 to pass the external pressurized harmful gas into the housing 1. The harmful gas first passes through the pre-filter cotton 122 in the first filter area 12. After being filtered by the pre-filter cotton 122, the particles in the harmful gas can be effectively blocked, preventing the particles from directly entering the second filter area 13 and causing the activated carbon in the second filter area 13 to be quickly blocked.

[0029] After being filtered by the pre-filter cotton 122, the harmful gas enters the second filter area 13. The drawer pull box 15 located in the second filter area 13 contains activated carbon adsorbent, which includes but is not limited to activated carbon granules, activated carbon honeycomb blocks, and activated carbon bricks, to filter the harmful gas again, thereby achieving the effect of filtering the harmful gas.

[0030] The device is provided with the first air duct 3, the second air duct 4, and the third air duct 5, so that the harmful gases entering the second filter area 13 can pass through the upper end opening of the drawer pull box 15 uniformly, and then fully contact with the activated carbon in the drawer pull box 15, thereby preventing some harmful gases from directly passing through the second filter area 13 and being discharged from the air outlet 14;

[0031] When the harmful gas passes through the first air duct 3, the second air duct 4, and the third air duct 5, the gas pushes the first dial plate 161 and the second dial plate 171 respectively, causing the first dial plate 161 and the second dial plate 171 to rotate. In the initial state, the first dial plate 161 and the second dial plate 171 are restricted by the first torsion spring 165 and the second torsion spring, and an acute angle is formed between the first dial plate 161 and the second dial plate 171 and the drawer pull box 15 (refer to FIG. Figure 3 ), and when the gas pushes the first dial plate 161 and the second dial plate 171, the first dial plate 161 and the second dial plate 171 are perpendicular to the drawer pull box 15 (refer to Figure 4 ), and after the first and second dial plates 161, 171 are rotated by the gas, one end of the first and second dial plates 161, 171 extends into the drawer pull box 15 and contacts the activated carbon in the drawer pull box 15. Therefore, when the harmful gas passes through the first and second dial plates 161, 171, the harmful gas can pass through the drawer pull box 15 without being blocked by the first and second dial plates 161, 171. This makes it possible for the harmful gas entering the housing 1 from the air inlet 11 to more fully contact the activated carbon in the drawer pull box 15 compared to the prior art, thereby improving the performance of adsorbing harmful gases.

[0032] Example 2: Reference Figure 3 , a VOCS activated carbon gas adsorption bed in an environment, which is basically the same as that in Example 1, further comprising: a limiting frame 121 is symmetrically fixedly connected to the housing 1 located in the first filter area 12, and a front filter cotton 122 is slidably connected to the limiting frame 121;

[0033] The provided limiting frame 121 can facilitate the insertion and installation of the pre-filter cotton 122 into the first filter area 12 .

[0034] Example 3: Reference Figure 4 A VOCS activated carbon gas adsorption bed for an environment is substantially the same as that of Example 2, with the further feature that: rectangular grooves 162 are formed at both ends of a rotating shaft 16, a rectangular block 164 is slidably connected in the rectangular groove 162, a connecting shaft 163 is fixedly connected to the rectangular block 164, a mounting cover 166 is rotatably connected to the connecting shaft 163, a first torsion spring 165 is fixedly connected between the rectangular block 164 and the mounting cover 166, and the mounting cover 166 is connected to the housing 1;

[0035] Place the rotating shaft 16 together with the first shift plate 161 in the housing 1, hold the installation cover 166, pass the rectangular block 164 through the housing 1 into the housing 1, and insert it into the rectangular groove 162 at one end of the rotating shaft 16, so that the rotating shaft 16 is rotatably connected to the housing 1 through the connecting shaft 163, thereby facilitating installation and disassembly.

[0036] The utility model is provided with the first air duct 3, the second air duct 4, and the third air duct 5, so that the harmful gas entering the second filter area 13 can uniformly pass through the upper end opening of the drawer pull box 15, and then fully contact with the activated carbon in the drawer pull box 15, thereby preventing some of the harmful gas from directly passing through the second filter area 13 and being discharged from the air outlet 14;

[0037] When the first and second plates 161, 171 rotate due to the push of the gas, one end of the first and second plates 161, 171 extends into the drawer pull box 15 and contacts the activated carbon in the drawer pull box 15. Therefore, when the harmful gas passes through the first and second plates 161, 171, the harmful gas can pass through the drawer pull box 15 without being blocked by the first and second plates 161, 171. This makes it possible for the harmful gas entering the housing 1 from the air inlet 11 to more fully contact the activated carbon in the drawer pull box 15 compared to the prior art, thereby improving the performance of adsorbing harmful gases.
