Description

A waste gas collection and purification device for oily sewage pools

technical field

The utility model relates to the treatment of volatile organic waste gas from oily sewage pools in the production process of the petrochemical industry, belongs to the field of environmental protection equipment, and particularly relates to a collection and purification device for oily sewage pools.

Background technique

The petrochemical industry will produce a large amount of oily wastewater in the production process. The wastewater has complex components and mainly contains a large amount of volatile organic compounds, such as benzene, toluene, ethylbenzene and other toxic and harmful substances. Although some petrochemical enterprises have covered them, they have not. The further collection and purification of the oily sewage pool will cause the volatile organic compounds (VOCs) in the sewage pool to escape directly into the atmosphere, causing serious stench near the oily sewage pool, which will not only pose a great threat to the human health of the staff, but also cause Cause environmental pollution.

Contents of the invention

In order to improve the above situation, the utility model provides a collection and purification device for oily sewage pools, which collects and purifies the volatile organic compounds escaped from the oily sewage pools in the petrochemical industry, which can reduce the fugitive emission of volatile organic compounds.

The technical scheme adopted by the utility model is: a collection and purification device for oily sewage pool is composed of four parts: collection device, purification device, air induction device and detection device. The pipeline, wherein the sealing device of the sewage pool is located above the sewage pool, the gas collecting hood is located inside the sealing device of the sewage pool, one end of the gas collecting pipeline is connected with the gas collecting hood, and the other end is connected with the purification device; Spray absorption device and activated carbon adsorption device. One end of the acidic spray absorption device is connected to the gas collection pipe, the other end is connected to the alkaline spray absorption device, and the other end of the alkaline spray absorption device is connected to the activated carbon adsorption device; The air induction pipe opening and the sampling head of the detection device are located in the ventilation duct at the rear end of the purification device, and the sampling head is located behind the air induction pipe opening.

The acidic spray absorption device is composed of acid liquid spray head, acid liquid collection bucket and box; the alkaline spray absorption device is composed of lye spray head, lye collection bucket and box body.

The beneficial effect is: it can effectively remove volatile organic pollutants in oily sewage; the structure is simple and easy to operate; the cost is low and easy to popularize.

detailed description

Below in conjunction with accompanying drawing 1 the present invention is further described.

Sewage pool sealing device 1 is located above the oily sewage pool to seal the pool body to prevent the diffusion of volatile organic compounds and facilitate the collection of volatile organic compounds. Under the action of wind, the volatile organic compounds in the sewage pool enter the gas collection pipe 3 through the gas collection hood 2, and enter the acid spray absorption device box 4 along the gas collection pipe 3, and the acid liquid spray head 5 sprays acid liquid to decompose the stench The macromolecular organic matter in the gas, the absorption liquid falls into the acid liquid collection bucket 8 and is recovered for treatment, and the waste gas after treatment enters the alkaline spray absorption device box 7, and the alkaline liquid spray head 6 sprays the alkaline liquid mainly Absorb the acidic odor hydrogen sulfide in the waste gas, the absorption liquid falls into the lye collecting bucket 9 and recovers for treatment, then the waste gas enters the activated carbon adsorption device box 11 through the ventilation duct 10, and the activated carbon in the box absorbs the remaining large amount of waste gas in the waste gas. For some volatile organic compounds, the air-introduction nozzle 16 of the induced draft fan 15 is placed at the front end of the ventilation duct 12 at the rear end of the activated carbon adsorption device casing 11, and the sampling head 13 of the detector 14 is located at the ventilation duct 12 at the rear end of the activated carbon adsorption device casing 11 At the rear end of the system, the detector 14 detects the emission concentration of pollutants in the treated tail gas in real time through the sampling head 13 .
