Petrochemical gas filtering and discharging device

Abstract

The invention belongs to the technical field of petrochemical engineering, and particularly relates to a petrochemical engineering gas filtering and discharging device. The device comprises a desulfurization tower being connected with an external exhaust emission device and an exhaust tower used for discharging purified gas. The outer wall of the desulfurizing tower is connected with a gas inlet pipe for feeding gas, and the top of the desulfurizing tower is connected with a gas outlet pipe for gas exhaust. The air outlet pipe is connected with the air suction end of an induced draft fan, andthe air exhaust end of the induced draft fan is connected with a pipeline device. The pipeline device is connected with a gas pipe A and a gas pipe B, which are parallel to each other. According to the chemical gas filtering and discharging device, two gas pipes are connected with two groups of activated carbon boxes, and when air is filtered, a single gas pipe is connected with a single activatedcarbon box for waste gas filtering; when the activated carbon plates in one group of activated carbon boxes cannot treat the waste gas to reach the emission standard, the waste gas transmission is cut off through the gas valve, and another gas pipe is employed to cooperate with another activated carbon box for waste gas treatment. Based on the technical scheme, the exhausted gas can reach the emission standard, and the progress of petroleum processing and production is not affected.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to a petrochemical gas filtering and discharging device. Background technique [0002] Petrochemical industry, referred to as petrochemical industry. Generally refers to the chemical industry that uses petroleum and natural gas as raw materials, which will produce chemical pollution during production. Chemical pollution refers to waste gas and pollutants generated during the production process of the chemical industry. Most of these wastes are harmful above a certain concentration. It is a highly toxic substance that will cause pollution if it enters the environment. [0003] When the existing petrochemical gas filtration and discharge device is in use, after the activated carbon box in the adsorption device has been used for a period of time, the internal activated carbon plate absorbs too much particulate impurities in the exhaust gas, resulting in overfilling of the gaps ...

Problems solved by technology

[0003] When the existing petrochemical gas filtration and discharge device is in use, after the activated carbon box in the adsorption device has been used for a period of time, the internal activated carbon plate absorbs too much particulate impurities in the exhaust gas, resulting in overfilling of the gaps in the activated carbon plate and reducing the absorption efficiency. 60%, resulting in the exhausted gas failing to meet the emission standards, and the maintenance of the activated carbon box requires the shutdown of oil processing and production, which affects the progress of production
