Laboratory VOCs treatment device and treatment method thereof

Abstract

The invention discloses a laboratory VOCs treatment device which comprises a collecting device, and an isolating device is arranged at the top of the collecting device. through cooperation of the collecting device, the isolating device, a transmission device, a feeding device and an adsorption device, the laboratory VOCs treatment device can automatically replace preferentially saturated activatedcarbon on the air source side, it is ensured that the effective length of an activated carbon column is within a safe range, the retention time of waste gas in the activated carbon is long enough, itis ensured that the waste gas is fully purified, purified air can reach the standard, and environmental pollution cannot be caused. People can supplement activated carbon into the feeding device in time through a warning device, the activated carbon can enter the adsorption device more smoothly through cooperation of the transmission device and a rapping device, and the activated carbon can enterthe adsorption device more smoothly. Through a prompt device, people can timely and intensively treat saturated activated carbon in the collecting device, so that the practicability of the laboratoryVOCs treatment device is improved.

Description

technical field [0001] The invention relates to the field of laboratory VOCs processing devices, and more specifically, relates to a laboratory VOCs processing device and a processing method thereof. Background technique [0002] The laboratory is the place where the test is carried out. The exhaust gas in the laboratory is produced by various tests. It has the characteristics of many types of pollutants, complex components, and intermittent emissions. The pollutants in the exhaust gas mainly include organic gases and inorganic gases. Large categories, among which organic gases are also called volatile organic compounds, which are often expressed as VOCs. VOCs are usually formed by the volatilization of low-boiling organic compounds such as carbon tetrachloride, methane, ether, ethanethiol, benzene, and aldehydes. These VOCs participate in the atmospheric environment. The formation of ozone and secondary aerosols has an important impact on regional atmospheric ozone pollutio...

Problems solved by technology

[0003] The existing activated carbon adsorption device is mainly composed of a fan, a storage box, and an air duct. When in use, the activated carbon is directly poured into the storage box to form a carbon column, and then the exhaust gas driven by the fan enters the storage box through the air duct and passes through the activated carbon. The exhaust gas is purified by activated carbon. However, with the prolongation of the use time, the activated carbon near the gas source will inevitably be saturated preferentially, which will lead to a decrease in the effective length of the carbon column, shorten the residence time of the exhaust gas in the activated carbon, and purify the exhaust gas. The effect is reduced, and the purified air is not up to standard, which will pollute the environment. Therefore, it is urgent to design a laboratory VOCs treatment device
