Description

VOCs preprocessing device

Technical Field

The utility model relates to a VOCs preliminary treatment equipment technical field, concretely relates to VOCs preprocessing device.

Background

VOCs are various organic compounds with boiling points of 50-260 ℃ at normal temperature, in China, VOCs refer to all organic compounds with saturated vapor pressure of more than 70Pa at normal temperature and boiling points of 260 ℃ below normal pressure, or all organic compounds with vapor pressure of more than or equal to 10Pa and volatility at 20 ℃, most VOCs have uncomfortable special odor in environmental monitoring, and have toxicity, irritation, teratogenicity and carcinogenic effect, and especially benzene, toluene, formaldehyde and the like cause great harm to human health.

Although current VOCs active carbon adsorption preprocessing device can carry out the preliminary treatment to VOCs through the active carbon, nevertheless have current VOCs active carbon adsorption preprocessing device to carry out the during operation, the active carbon is whole to be filled in the box, and the active carbon quantity is more and the contact time of waste gas and active carbon is shorter, and the preliminary treatment effect is not good.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem and providing a VOCs pretreatment device.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a VOCs pretreatment device comprises a box body, wherein neutralizing liquid is stored in the box body, the side wall of the box body is communicated with a liquid inlet pipe, a liquid outlet pipe and an air inlet pipe, and one end part of the air inlet pipe extends to the position below the liquid level of the neutralizing liquid;

a horizontally placed partition plate is arranged in the box body, the edge of the partition plate is connected with the inner side wall of the box body, an air inlet is formed in the partition plate, an annular pipeline is communicated above the air inlet, and activated carbon is filled in the annular pipeline;

the top of the annular pipeline is provided with an exhaust port, and the top of the box body is communicated with an exhaust pipe.

Furthermore, a separation net is arranged at the joint of the air inlet and the annular pipeline.

Furthermore, an overflow pipe is communicated with the side wall of the box body.

Furthermore, a base is connected to the lower portion of the box body.

Furthermore, valves are arranged in the liquid inlet pipe and the liquid outlet pipe.

Further, the horizontal height of the overflow pipe is lower than that of the liquid inlet pipe and higher than that of the liquid outlet pipe.

Furthermore, two sides of the annular pipeline are connected to the inner side wall of the box body.

Furthermore, one end of the overflow pipe, which is far away from the box body, is communicated with the liquid outlet pipe.
