Efficient waste gas purifying device based on microwave catalysis

Abstract

The invention discloses an efficient waste gas purifying device based on microwave catalysis. The efficient waste gas purifying device comprises a spraying device, a gas dehydrating unit, a gas conveying device, gas flow control devices and microwave catalysis devices. A waste gas inlet is formed in one end of the spraying device, the other end of the spraying device is connected with a gas inlet of the gas dehydrating unit, a gas inlet of the gas conveying device is connected with a gas outlet of the gas dehydrating unit, and the two ends of each gas flow control device are connected with a gas inlet of the corresponding microwave catalysis device and a gas outlet of the gas conveying device respectively. Waste gas enters the spraying device through the waste gas inlet to be purified preliminarily and then enters the microwave catalysis devices through the gas dehydrating unit, the gas conveying device and the gas flow control devices sequentially to be purified secondarily, the waste gas is purified into clean gas through the microwave catalysis devices to be exhausted, and one or at least two gas outlets are formed in the gas conveying device. The efficient waste gas purifying device has the advantages of achieving accurate control and multiple purification, and being convenient to maintain, long in service life and high in waste gas purification rate.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a microwave-catalyzed high-efficiency waste gas purification device. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially in chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted is very smelly, which seriously pollutes the environment and affects human health. Physiological mechanisms that cause irreparable damage. [0003] Air pollution is mainly caused by the discharge of various pollutant gases into the air during the combustion and processing of energy fuels required by industry. Air pollutants include: sulfur dioxide, soot, industrial dust and nitrogen oxides. The harm of air pollutants to the human body is mainly manifested in respiratory diseases and physiological mechanism disorders. Exhaust g...

AI Technical Summary

Problems solved by technology

The harm of air pollutants to the human body is mainly manifested in respiratory diseases and physiological mechanism disorders. Exhaust gas will cause temporary and permanent lesions in the human respiratory, blood, liver and other systems and organs; the harm to plants is mainly reflected in the leaf color and light of plants. In terms of cooperation, more serious air pollution will cause acute damage to plants, causing discoloration and spots on the surface of plant leaves, and even causing leaves to wither and fall off. Even if the air pollution is not serious, it will cause chronic damage to plants. There are no harmful symptoms, but the physiological functions of plants have been affected. Plants growing in the polluted atmosphere for a long time will cause plant yields to decline and quality to deteriorate; the impact on the weather and climate is mainly manifested in the greenhouse effect and smog. Dust and toxic gases in the air can cause smog weather, which can cause serious damage to human plants and cause traffic accidents
