Adsorption tower for VOCs gas emission treatment

Abstract

The invention discloses an adsorption tower for VOCs gas emission treatment, wherein the adsorption tower comprises a first treatment tower, a temperature sensor, a membrane separation device and a third connecting pipe; the left side of the first treatment tower is connected with a supercharging device, the end, away from the first treatment tower, of the supercharging device is connected with a gas inlet pipe, and the lower end of the first treatment tower is connected with a first liquid conveying pump; and the end, away from the first treatment tower, of the first liquid conveying pump is connected with a liquid supply box, the temperature sensor is arranged in the liquid supply box in a penetrating mode, and the liquid supply box is connected with a cooling mechanism through a second liquid conveying pump. According to the adsorption tower for VOCs gas emission treatment, a demister is arranged in the first treatment tower, under the action of the demister, mist particles in treated gas can be adsorbed, the influence of the mist particles on the interior of a subsequent pipeline is reduced, under the action of folded plates arranged in an up-down staggered mode, the time of the gas in the first treatment tower is delayed, an oil-gas mixture is in full contact with an absorbent, and organic components in the oil-gas mixture are absorbed.

Description

technical field [0001] The invention relates to the technical field related to VOCs gas, in particular to an adsorption tower for VOCs gas emission treatment. Background technique [0002] Because in the tank area, all oil storage tanks have large and small breathing, and nitrogen gas is required to seal with the large and small breathing, and to ensure the slight positive pressure of the tank body, and the nitrogen mixed with oil and gas that we used to seal is directly discharged, which is easy to cause the emission of VOCs Exceeding the standard will have an impact on the environment. Now it is necessary to use an adsorption tower for VOCs gas emission treatment to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide an adsorption tower for VOCs gas emission treatment to solve the problem that the previously sealed nitrogen mixed with oil and gas is directly discharged in the above-mentioned background technolog...
