Cooling and purifying environment protection system for industrial waste gas emissions

Abstract

The invention discloses a cooling and purifying environment protection system for industrial waste gas emissions used for treating original heat smoke gas emitted in industrial production, and solves the problem that a large amount of dust particles, other impurities and high temperature emissions in the original heat smoke gas pollute the outdoor environment. The system is especially suitable for a coating production line of biomass burning machine equipment in the heat source part. The dust removal efficiency is up to 90% or higher, so that the environment protection emission standard is beneficial for being met. Meanwhile, after being subjected to dust removal spraying, the original heat smoke gas of 120-220 DEG C is emitted into the outdoor environment in the temperature range of 50-80 DEG C, so that the environment protection emission standard is beneficial for being met. The system can safely treat high-temperature, high-humidity and inflammable gas, and is low in cost, and remarkable in cooling and purifying effect, free from secondary pollution, lower in consumption of clean water and treatment capacity of wastewater, low in operation cost and resource loss, and simple and convenient to use and maintain.

Description

technical field [0001] The invention relates to the technical field of purification of industrial waste gas discharge, in particular to an industrial waste gas discharge cooling and purification environmental protection system used in a coating production line. Background technique [0002] With the popularization and application of biomass gasification technology, biomass pellet burners are also used in the coating line as the heat source in the coating line. During the working process of the biomass pellet burner, the gasification of biomass pellets is accompanied by a large amount of smoke and dust, as well as some gaseous pollutants; considering the cost of using traditional waste gas treatment technology, these substances are usually discharged into the surrounding environment without perfect treatment , causing serious pollution to the environment. [0003] At present, the industry uses simple cyclone dust accumulation equipment to accumulate dust. However, it is only...
