Multistage purification environmental-protection device for chemical engineering exhaust gas treatment

Abstract

The invention provides a multistage purification environmental-protection device for chemical engineering exhaust gas treatment, and belongs to the technical field of exhaust gas purification treatment environmental protection. The device comprises a box body and a dust circulating box; and a first separator plate and a second separator plate are vertically arranged in the box body. A lot of wasteheat in chemical engineering exhaust gas is still not treated, a lot of heat contained in the exhaust gas heats cold water in a waste heat utilization box in a first exhaust gas inlet tube in a heattransfer manner, and the tube body of the tube adopts a snakelike bent structure to make the whole exhaust gas discharged after fully transferring heat with the cold water, so remaining heat in the gas can be practically recycled to avoid terrible energy waste caused by direct emission of traditional manners, the heated hot water can be used in all fields of people's lives, and the exhaust gas iswell effectively used, and is drawn into an exhaust gas pretreatment box after the heat is used.

Description

technical field [0001] The invention relates to the technical field of waste gas purification and environmental protection, in particular to a multi-stage purification and environmental protection device for chemical waste gas treatment. Background technique [0002] With the rapid development of today's society and the acceleration of China's industrialization process, the biochemical environment and air quality have deteriorated sharply. Industrial production is an important source of air pollution. There are many types of industrial air pollutants, including smoke, sulfur oxides, and nitrogen. Oxides, organic compounds, halides, carbon compounds, etc., when the concentration of pollutants in the atmosphere is very high, it will cause acute pollution poisoning, or make the disease worse, and even kill thousands of people in a few days. How to reduce atmospheric pollution? Pollution and reduction of industrial waste gas emissions are our top priority. Most of the purificati...

[0002] With the rapid development of today's society and the acceleration of China's industrialization process, the biochemical environment and air quality have deteriorated sharply. Industrial production is an important source of air pollution. There are many types of industrial air pollutants, including smoke, sulfur oxides, and nitrogen. Oxides, organic compounds, halides, carbon compounds, etc., when the concentration of pollutants in the atmosphere is very high, it will cause acute pollution poisoning, or make the disease worse, and even kill thousands of people in a few days. How to reduce atmospheric pollution? Pollution, reducing industrial waste gas emissions is our top priority. Most of the purification devices on the market are too independent and the effect is not obvious. Therefore, it is urgent to invent a new type of high-efficiency waste gas purification treatment device.
