AI Technical Summary
When treating industrial fumes, existing activated carbon purification boxes often experience clogging of the activated carbon layer due to fumes, resulting in insufficient purification. This is especially true when the intake volume of fumes increases rapidly, as the activated carbon layer cannot effectively buffer the flow, leading to inadequate purification.
A variable-volume activated carbon purification box was designed, which adopts an air intake control mechanism, including three ventilation plates and a partition plate. The shape of the ventilation plates is adjusted by spring tension, and the state of the ventilation plates is adjusted according to the change of flue gas volume to avoid flue gas blowing directly into the activated carbon layer. The baffle plate expands the contact area between flue gas and activated carbon.
This ensures that the flue gas can be evenly distributed and fully contacted with the activated carbon when the flue gas volume changes, avoiding blockage and ensuring the stability and efficiency of the purification effect. In particular, it can quickly pass through and fully treat the flue gas even with large air volumes.

[0002] With the gradual improvement of environmental protection consciousness, the equipment for purifying the environment is also improved, and the biggest pollution in the industrial production process is air pollution. A large amount of smoke and dust is discharged in the air during industrial production, which can easily cause serious air pollution. In order to avoid the pollution of a large amount of smoke generated by industrial production, the evolution equipment is used to treat the smoke;
[0003] When purifying the smoke generated by industry, the existing activated carbon purifying box is used for purification treatment. The purifying box is a box structure, one end is an air inlet, and the other end is an air outlet. A plurality of activated carbon layers are distributed in the purifying box. The smoke generated by industrial production enters the purifying box through the air inlet, is absorbed by the activated carbon layer, and is then discharged through the air outlet. The existing purifying box is not sufficient for smoke treatment, and the air inlet of the purifying box directly faces the activated carbon layer without a buffer device. When the smoke volume increases rapidly, the smoke directly blows on one part of the activated carbon layer, which can easily cause the activated carbon layer to be blocked, and the subsequent smoke cannot be fully treated. Therefore, we propose a variable processing air volume's activated carbon purifying box. SUMMARY
[0004] The utility model discloses a variable processing air volume's activated carbon purifying box to solve the problem in the background art.

[0006] As a preferred scheme of the variable processing air volume's activated carbon purification box, the air inlet control mechanism comprises three ventilation plates corresponding to the three pull-out boxes, the ventilation plate in the middle is located on one side of the other two ventilation plates, and the adjacent two ventilation plates are hinged with a partition plate, and the top wall and the bottom wall of the purification box body are respectively hinged with the side edges of the ventilation plates.
[0007] As a preferred scheme of the variable processing air volume's activated carbon purification box, the side wall of the partition plate is rotationally connected with the inner wall of the purification box body through a rotating shaft, the ventilation plate is made of thin steel plate, and a plurality of ventilation holes are uniformly distributed on the surface of the ventilation plate.
[0008] As a preferred scheme of the variable processing air volume's activated carbon purification box, the air inlet of the air guide barrel is provided with a mounting plate, the mounting plate corresponds to the ventilation plate located in the middle of the three ventilation plates, a spring is arranged between the mounting plate and the corresponding ventilation plate, the spring is in a stretched state, and the three ventilation plates become arched under the action of the tension of the spring.
[0009] As a preferred scheme of the variable processing air volume's activated carbon purification box, a flow guide piece is arranged in the gap between the adjacent pull-out boxes, and the flow guide piece comprises two eight-shaped flow guide plates.
[0010] As a preferred scheme of the variable processing air volume's activated carbon purification box, the width of the pull-out box located in the middle is smaller than the width of the other two pull-out boxes.
[0011] Compared with the prior art, the beneficial effects of the present application are:
[0012] In this invention, the air intake control mechanism buffers the flue gas entering the purification chamber, preventing it from directly blowing onto the activated carbon layer. The mechanism adjusts the state of the three ventilation plates according to the flue gas volume. When the volume is low, the central ventilation plate arches under spring tension, which in turn pulls the other two ventilation plates into arches by rotating the partition plate. The ventilation plates and partition plate allow the flue gas to briefly linger within the purification chamber and slowly diffuse through the three arched ventilation plates into the purification chamber, where it is absorbed by the activated carbon in the three pull-out boxes. Because the three ventilation plates are arched, the flue gas is sprayed towards the pull-out boxes as it passes through the multiple ventilation holes on the plates. The airflow can directly and fully contact the activated carbon on one side of the pull-out box. When the airflow is too large, the incoming flue gas blows directly onto the ventilation plate in the middle. The ventilation plate in the middle overcomes the spring force and pulls the other two ventilation plates to a more vertical state through the partition plate. Compared with the arched ventilation plate, the three ventilation plates in a more vertical state allow the flue gas to pass through the multiple ventilation holes on the ventilation plate more quickly. It can also expand the direction of the flue gas jet through the ventilation plate. This allows the flue gas to quickly pass through the three ventilation plates and not only contact the activated carbon on one side of the pull-out box, but also contact the activated carbon at the bottom or top of the pull-out box under the guidance of the guide plate and be fully treated. This ensures that the flue gas passes through quickly while fully contacting the activated carbon. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] Please see Figures 1-4The utility model relates to an active carbon purification box of variable processing air volume, including purification box body 100, one end of purification box body 100 is equipped with the air inlet pipe mouth 101, and the other end of purification box body 100 is equipped with the air outlet pipe mouth 102, and the lateral wall of purification box body 100 is spaced apart and is equipped with three pull -out openings 103 from top to bottom, and the inner wall of purification box body 100 is located three pull -out openings 103 and is provided with support plate 103a, and three pull -out openings 103 are respectively provided with purification piece 200, and purification piece 200 includes the pull -out box 201 of sliding setting in the top of support plate 103a, and the pull -out box 201 is drawer -like, and the left and right lateral wall and bottom wall of pull -out box 201 are hollow respectively, and the hollow place is provided with grid plate 202, and pull -out box 201 is provided with active carbon inside, and the air inlet pipe mouth 101 is provided with the air guide bucket 104 of circular table shape, and the inside of purification box body 100 is located between purification piece 200 and air guide bucket 104 and is provided with the air -intaking control mechanism 300.
[0020] The smoke pipe is connected with the air inlet pipe mouth 101 of the purification box body 100, the flue gas discharged by the smoke pipe enters the inside of the purification box body 100 through the air guide bucket 104 at the air inlet pipe mouth 101, and the air -intaking control mechanism 300 divides the inside of the purification box body 100 into two chambers, the flue gas enters the chamber with purification piece 200 after being hindered by the air -intaking control mechanism 300 first, avoids the flue gas directly blowing the corresponding purification piece 200, and makes the flue gas accumulate in the chamber between the air -intaking control mechanism 300 and the air inlet pipe mouth 101 and slowly enter the chamber with purification piece 200 to be treated fully.
[0021] In the embodiment, the air -intaking control mechanism 300 includes three ventilation plates 301 corresponding to three pull -out boxes 201, the ventilation plate 301 in the middle is located on one side of the other two ventilation plates 301, and the adjacent two ventilation plates 301 are hinged with a partition plate 302, and the top wall and the bottom wall of the purification box body 100 are hinged with the side of the ventilation plate 301 respectively.
[0022] Since the two ventilation plates 301 are hinged with the partition plate 302, the ventilation plate 30 can be rotated with the partition plate 302.
[0023] In the embodiment, the side wall of the partition plate 302 is rotationally connected with the inner wall of the purification box body 100 through the pivot 302a, the ventilation plate 301 is made of thin steel plate, and the surface of the ventilation plate 301 is uniformly distributed with a plurality of ventilation holes 301a.
[0024] Since the ventilation plate 301 is made of thin steel plate, the ventilation plate 301 is flexible and can be bent.
[0025] In this embodiment, the air inlet of the air guide barrel 104 is provided with a mounting plate 104a corresponding to the ventilation plate 301 located in the middle of the three ventilation plates 301, and a spring 303 is arranged between the mounting plate 104a and the corresponding ventilation plate 301. The spring 303 is in a tensile state, and the three ventilation plates 301 become arched under the tension of the spring 303.
[0026] Since the ventilation plate 301 is made of thin steel plate, when the middle ventilation plate 301 is subjected to the tension of the spring 303, it will become completely arched. Compared with the ventilation plate 301 in the vertical state, the arched ventilation plate 301 has a lower passing rate of flue gas when the flue gas directly blows on it due to the change of the angle of the ventilation hole 301a. After being subjected to the force of large amount of flue gas, the ventilation plate 301 overcomes the elastic force of the spring 303 and tends to be vertical, thereby accelerating the circulation of large amount of flue gas.
[0027] In this embodiment, a flow guide is arranged in the gap between adjacent pull-out boxes 201, and the flow guide includes two eight-shaped flow guide plates 304.
[0028] When the flue gas flows through the gap between adjacent pull-out boxes 201, the flue gas contacts the activated carbon at the top or bottom of the pull-out box 201 under the flow guiding effect of the two eight-shaped flow guide plates 304, so that the flue gas can be more fully treated.
[0029] In this embodiment, the width of the pull-out box 201 located in the middle is smaller than the width of the other two pull-out boxes 201.
[0030] When the middle ventilation plate 301 changes from an arched shape to a vertical state, the entire ventilation plate 301 will be displaced by a distance towards the middle pull-out box 201. The width of the middle pull-out box 201 is smaller than the width of the other two pull-out boxes 201, which can ensure that the middle ventilation plate 301 can also provide a certain gap after displacement to facilitate the dispersion of flue gas.
[0031] Working principle: connect the flue gas pipeline with the gas inlet pipe 101 of the purification box 100, the flue gas discharged by the flue gas pipeline enters the inside of the purification box 100 through the wind guide barrel 104 at the gas inlet pipe 101, and the air inlet control mechanism 300 divides the inside of the purification box 100 into two chambers, the flue gas entering the inside of the purification box 100 is first hindered by the air inlet control mechanism 300, avoiding the flue gas directly blowing the corresponding purification piece 200, when the flue gas air inlet amount is not large, the flue gas entering the inside of the purification box 100 is first hindered by the ventilation plate 301 and the partition plate 302 and slowly accumulates in the chamber between the air inlet control mechanism 300 and the gas inlet pipe 101, and is diffused to the inside of the purification box 100 and the activated carbon in the pull-out box 201 through the multiple ventilation holes 301a on the three ventilation plates 301, since the initial state of the three ventilation plates 301 is arched, when the flue gas passes through the multiple ventilation holes 301a on the three ventilation plates 301, the injection angle of the flue gas is towards the side of the pull-out box 201, which can directly and fully contact the activated carbon on the side of the pull-out box 201 and slowly diffuse to the inside of the purification box 100 and the pull-out box 201, when the flue gas air inlet amount increases, the flue gas directly blows the ventilation plate 301 in the middle, the ventilation plate 301 overcomes the pulling force of the spring 303 and slowly tends to be vertical, the ventilation plate 301 in the middle pulls the partition plate 302 to rotate and in turn drives the other two ventilation plates 301 to also tend to be vertical, compared with the arched ventilation plate 301, the three ventilation plates 301 tending to be vertical can make the flue gas pass through the multiple ventilation holes 301a on the ventilation plate 301 faster, and can also expand the injection direction of the flue gas passing through the ventilation plate 301, avoiding that the air volume is too large and a large amount of flue gas accumulates in the chamber between the air inlet control mechanism 300 and the gas inlet pipe 101 in a short time, after passing through the three ventilation plates 301, part of the flue gas contacts the activated carbon on the side of the three pull-out boxes 201, and the other part contacts the activated carbon on the top or bottom of the pull-out box 201 when flowing through the gap between the adjacent pull-out boxes 201, so that the flue gas entering the purification box 100 in a large air volume can also be fully treated.
