Description

Technical Field

[0001] The invention relates to the technical field of waste heat recovery, and in particular to an industrial waste gas waste heat recovery device. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes within the factory area of ​​an enterprise. Industrial waste gas usually contains pollutants such as smoke and industrial dust. The discharge of industrial waste gas into the atmosphere will pollute the air. These pollutants enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have an accumulation effect, which will more seriously endanger human health. Industrial waste gas contains a large amount of heat energy, and waste heat recovery equipment is usually used to recycle and reuse the heat in the industrial waste gas.

[0003] At present, the industrial waste gas waste heat recovery devices on the market have low recovery efficiency and do not have the function of purifying pollutants such as smoke and productive dust in the waste gas, which leads to the emission of waste gas into the atmosphere, which is easy to cause environmental pollution. In the related technology, a spray mechanism and a filter are set at the feed port of the industrial waste gas waste heat recovery device. Although it can play a filtering role, in actual use, the spray range of the spray mechanism is limited, resulting in the inability to spray and filter all the dust in the waste gas. The cleaning is not thorough enough, resulting in the subsequent waste gas being discharged into the atmosphere. After that, it will still cause pollution, which has certain limitations.
