Description

Technical Field

[0001] The invention relates to a volatile organic compound treatment system, belonging to the technical field of air pollution treatment. Background Art

[0002] Volatile organic compounds, abbreviated as VOCs, refer to various organic compounds with a boiling point of 50°C to 260°C at room temperature. VOCs are one of the important precursors for the formation of ozone and fine particulate matter, which can cause atmospheric photochemical smog pollution and aggravate the greenhouse effect. At the same time, they can cause damage to the human nervous system, liver, kidneys and other organs. Therefore, volatile organic compounds must be treated.

[0003] The current mainstream process for treating volatile organic compounds is activated carbon adsorption plus desorption plus catalytic combustion. This process uses the porosity of activated carbon to adsorb VOCs. When the activated carbon is saturated with adsorption, hot air is introduced into the activated carbon for desorption to restore its adsorption capacity; and the desorbed VOCs are introduced into a catalytic combustion device, where they are oxidized and decomposed into carbon dioxide and water under the action of the catalyst.

[0004] Since activated carbon cannot be adsorbed during desorption, the existing activated carbon adsorption and desorption plus catalytic combustion system needs to be equipped with an additional set of activated carbon boxes, and adsorption valves and desorption valves are installed on the front and back sides of each set of activated carbon boxes. When a set of activated carbon boxes needs to be desorbed, the adsorption valves on both sides are closed, and the desorption valves are opened at the same time, and then hot air is introduced for desorption. The additional activated carbon boxes need to be equipped with corresponding connecting pipes, valves and instruments, which greatly increases the production cost and floor space of the treatment system, and also increases the on-site construction and subsequent maintenance costs of the system. Summary of the invention

The filter 1 is provided with a multi-stage filtering device inside to intercept particulate matter in the gas and prevent the activated carbon at the rear from being blocked.

[0046] The working process of the present invention is:

[0047] Adsorption process:

[0048] 1. The gas containing VOCs passes through filter 1 to filter out the particulate matter in the gas;

[0049] 2. The gas enters the dynamic activated carbon box 2 from the adsorption port 2032. The activated carbon in the dynamic activated carbon box 2 adsorbs VOCs in the gas. The gas with VOCs removed is discharged into the atmosphere through the exhaust pipe 4 under the gravitational effect of the adsorption fan 3.

[0050] Desorption process:

[0051] 1. The motor 202 is activated to drive the desorption box 210 to move to the two sides of the activated carbon drawer 211 to be desorbed. The cylinder 2102 is activated to push the movable sealing plate assembly so that the movable sealing plate 2104 is close to the two sides of the activated carbon drawer 211. At this time, the movable sealing plate 2104 and the activated carbon drawer 211 are sealed by the sealing strip B2105, and the movable sealing box 2103 and the desorption box housing 2101 are sealed by the sealing strip C2106. At the same time, the sealing valve plate 21032 is separated from the air outlet of the desorption box housing 2101, and the desorption pipeline is connected;

[0052] 2. The fresh air fan 6 is activated. Fresh air is filtered by the air filter 5 and enters the heat exchanger 7. After the fresh air is heated to 80°C by the high-temperature gas discharged from the catalytic combustion device 8, it enters the dynamic activated carbon box 2 through the desorption port 2031. The gas passes through the fixed box 208, the swing arm assembly 209 and the desorption box 210 in turn and enters the activated carbon drawer 211 to desorb the activated carbon.

[0053] When the activated carbon drawer to be desorbed has completed desorption, the cylinder 2102 drives the movable sealing plate assembly to withdraw as a whole, so that the movable sealing plate 2104 is separated from the activated carbon drawer 211, and at the same time the sealing valve plate 21032 blocks the air outlet on the desorption box shell 2101 to prevent the adsorbed airflow from entering the desorption pipeline;

[0054] The motor 202 is activated again to drive the desorption box 210 to move to the two sides of the next activated carbon drawer to be desorbed, and the desorption process step 1 is repeated, and the cycle is repeated;

[0055] 3. The desorbed high-concentration VOCs are discharged from the desorption port on the other side of the dynamic activated carbon box 2, and enter the catalytic combustion device 8 under the gravitational effect of the desorption fan 9, and are oxidized and decomposed into carbon dioxide and water;

[0056] 4. The treated high-temperature gas enters the heat exchanger 7, exchanges heat with fresh air to become low-temperature gas, and is discharged into the atmosphere through the exhaust pipe 4.

[0057] The adsorption and desorption processes proceed simultaneously.
