Technical Field

[0001] The invention relates to the field of organic waste gas, in particular to an adsorption box for treating VOCs organic waste gas. Background Art

[0002] VOCs organic waste gas is volatile organic compounds and a common air pollutant. It is produced in paint production, chemical fiber industry, metal coating, chemical medicine, automotive electronics, building materials and furniture, new materials and new energy industries.

[0003] In the existing technology, in the treatment process of low-concentration VOCs organic waste gas, the adsorption method has good treatment effect and is one of the most widely used methods. Commonly used adsorbents include activated carbon, diatomaceous earth, zeolite, etc., among which activated carbon adsorption is the most widely used. Through the activated carbon adsorption system, not only can the VOCs concentration be greatly reduced to achieve standard emission of waste gas, but also after adsorption, it can be desorbed by gas stripping, and the collected material can be returned to production for recycling. The adsorption box is an equipment component that must be used in the adsorption process.

[0004] However, before entering the adsorption box, VOCs organic waste gas comes into contact with the air, and there are a large number of impurity particles in the air. These impurity particles will enter the adsorption box together with the VOCs organic waste gas and pass through the activated carbon plate. Over time, a large amount of impurities will be adsorbed on the surface of the activated carbon plate, causing blockage of the activated carbon plate and affecting the adsorption effect of the activated carbon plate.

[0012] Preferably, the support rods are provided in three groups, and the three groups of support rods are distributed in a circle on the outer surface of the guide rod, and one group of support rods is fixedly connected to the inner surface of the shield.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the transmission track rotates, it will push the baffle plate through the transmission shaft to move along the limit block toward the principle axis direction, so that the air inlet pipe opening is gradually opened.

The rotation of the brush will clean the impurities adsorbed on the surface of the filter plate to prevent the filter plate from being blocked and affecting its function. When the brush is worn due to long-term use, the elasticity of the spring will support the push plate, so that the brush is always in close contact with the surface of the filter plate, thereby improving the stability of cleaning the filter plate. This structure realizes the function of the adsorption box body to pre-filter the VOCs organic waste gas before treating it. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A transmission track 15 is fixed to the outer surface of the end of the guide rod 25. Since the trajectory of the transmission track 15 is from the center of the circle to the outside, when the transmission track 15 rotates, it will push the baffle 5 to move along the limit block 9 toward the principle axis through the transmission shaft 12, so that the air inlet pipe port 2 is gradually opened. A support ring 4 is fixed to the end of the transmission track 15, and a support rod 22 is fixed to the outer surface of the middle part of the guide rod 25. A storage rod 23 is fixed to the side surface of the support rod 22. A telescopic rod 20 is movably provided inside the storage rod 23. A brush 21 is fixed to the end of the telescopic rod 20. The rotation of the support rod 22 will drive the brush 21 fixed on the surface of the push plate 18 to rotate around the axis of the guide rod 25 through the telescopic rod 20. The rotation of the brush 21 will clean the impurities adsorbed on the surface of the filter plate 6 to prevent the filter plate 6 from being blocked and affecting its function.

[0035] On the basis of Example 1, in order to enable the adsorption box main body 1 to pre-filter the VOCs organic waste gas before treating it, a limiting block 9 is fixed to the end of the air inlet pipe port 2, a connecting groove 13 is provided on the inner surface of the baffle 5, and a limiting groove 14 is provided on the inner wall of the connecting groove 13. The limiting block 9 corresponds to the limiting groove 14 and is clamped to be movably connected. On the one hand, the baffle 5 and the air inlet pipe port 2 are movably connected, and on the other hand, the baffle 5 is limited to prevent it from being separated from the air inlet pipe port 2.

[0036] A through groove 11 is provided on the outer surface of the air inlet pipe port 2, and the through groove 11 is connected with the air inlet pipe port 2 and the inner groove 10.

The transmission shaft 12 corresponds to and is clamped with the transmission track 15, and is movably connected. The rotation of the guide rod 25 will drive the transmission track 15 to rotate. Since the trajectory of the transmission track 15 is from the center of the circle to the outside, when the transmission track 15 rotates, the baffle 5 will be pushed by the transmission shaft 12 to move along the limit block 9 toward the principle axial direction, so that the air inlet pipe port 2 is gradually opened, and the baffle 5 is located between the support ring 4 and the air inlet pipe port 2.

[0038] A through hole 8 is provided on the surface of the filter plate 6, and the through hole 8 penetrates the filter plate 6. An annular groove 7 is provided on the inner wall of the through hole 8. An annular block 24 is fixed to the outer surface of the end of the guide rod 25 near the adsorption box body 1. The annular block 24 corresponds to the annular groove 7 and is movably clamped. On the one hand, the filter plate 6 and the guide rod 25 are movably connected, and on the other hand, the guide rod 25 is limited to prevent the guide rod 25 from deflecting when rotating.

[0039] There are three groups of support rods 22, which are distributed in a circle on the outer surface of the guide rod 25. One group of support rods 22 is fixedly connected to the inner surface of the baffle 3. The rotation of the baffle 3 will drive the guide rod 25 to rotate through the support rods 22.

[0040] The shielding plate 3 corresponds to the inner groove 10, and the two have the same curvature. The inner groove 10 is three-quarters of a circle, and the through groove 11 is a quarter of a circle. The gripping plate 16 corresponds to the through groove 11 and is clamped to form a movable connection.

[0042] A spring 17 is provided on the movable sleeve on the outer surface of the storage rod 23. When the brush 21 is worn out after long-term use, the elasticity of the spring 17 will support the push plate 18, so that the brush 21 is always in close contact with the surface of the filter plate 6, thereby improving the stability of cleaning the filter plate 6. A push plate 18 is fixed to the end of the telescopic rod 20, and the push plate 18 is fixed with a brush 21 on the side surface of the adsorption box body 1.

[0043] The diameter of the fixing plate 19 is the same as the diameter of the storage groove 27, the diameter of the telescopic rod 20 is the same as the diameter of the slot 26, the diameter of the storage groove 27 is larger than the diameter of the slot 26, and the fixing plate 19 and the storage groove 27 are movably clamped, on the one hand, the telescopic rod 20 and the storage rod 23 are movably connected, and on the other hand, the telescopic rod 20 is limited to prevent the telescopic rod 20 from being separated from the storage rod 23.

[0044] In actual use, the baffle plate 3 is driven to rotate in the inner groove 10 through the grip plate 16. The rotation of the baffle plate 3 will drive the guide rod 25 to rotate through the support rod 22. The rotation of the guide rod 25 will drive the transmission track 15 to rotate. Since the trajectory of the transmission track 15 is from the center of the circle to the outside, the transmission track 15 will push the baffle plate 5 to move along the limit block 9 toward the principle axis through the transmission shaft 12 when it rotates, so that the air inlet pipe 2 is gradually opened. When it is opened to the required size, VOCs organic waste gas can enter. The impurity particles in the incoming VOCs organic waste gas will be filtered by the filter plate 6, so that they will not be adsorbed on the activated carbon plate. The baffle plate 5 has two functions. One function is to control the movement of the baffle plate 5 to control the air intake rate of the VOCs organic waste gas. The other function is that when the adsorption box body 1 is no longer in use, the baffle plate 5 can be used to close the air intake. The air pipe opening 2 prevents dust from entering the adsorption box body 1; at the same time, when the guide rod 25 rotates to drive the baffle 5 to move, it will drive the support rod 22 to rotate. The rotation of the support rod 22 will drive the brush 21 fixed on the surface of the push plate 18 to rotate around the axis of the guide rod 25 through the telescopic rod 20. The rotation of the brush 21 will clean the impurities adsorbed on the surface of the filter plate 6 to prevent the filter plate 6 from being blocked and affecting its function; a spring 17 is provided between the push plate 18 and the side surface of the support rod 22, and the telescopic rod 20 is movably connected to the storage rod 23, so when the brush 21 is worn out after long-term use, the elasticity of the spring 17 will support the push plate 18, so that the brush 21 is always in close contact with the surface of the filter plate 6, thereby improving the stability of cleaning the filter plate 6. This structure realizes the function of the adsorption box body 1 to pre-filter VOCs organic waste gas before treating it.
