Problems solved by technology

[0002] A large amount of waste gas will be generated in the process of industrial production. If it is directly discharged to the atmosphere after being treated by purification equipment, although the impact on air pollution is reduced, the waste heat is not utilized, resulting in a large amount of energy waste.
[0003] At present, there are devices on the market that recover waste heat from exhaust gas, but most waste heat recovery devices are mainly for fresh air recovery, and the higher the recovery efficiency, the more complicated the structure of the device
At the same time, if the exhaust gas contains a large amount of oily fibrous substances, after the waste heat recovery device has been used for a long time, the oily substances will adhere to the surface of the device, which will lead to a gradual decline in heat exchange efficiency and affect the effect of waste heat recovery. It can be seen that cleaning has become an important issue

Abstract

The invention discloses a self-cleaning waste gas waste heat recovery device which comprises a rack. A waste gas air inlet used for being connected with a high-temperature waste gas pipeline is formed in the front end of the rack, and a waste gas air outlet used for discharging the heat exchange waste gas is formed in the rear end of the rack. A split type heat exchanger, a rapid brush replacing and cleaning mechanism and a cleaning driving mechanism are arranged in the rack. The rapid brush replacing and cleaning mechanism and the cleaning driving mechanism are connected with a PLC used for achieving automatic control over the cleaning process. According to the method, secondary recovery can be carried out on the waste heat generated by industrial waste gas, and self-cleaning can be carried out regularly, so that the problem of waste of waste heat is well solved, the cleaning effect is good, the cleaning process is thorough, and the oil removal speed can be adjusted according to the actual conditions, and thus the device is suitable for the occasions with more waste heat emission.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to an industrial waste gas waste heat recovery device with a self-cleaning mechanism. Background technique [0002] A large amount of waste gas will be generated in the process of industrial production. If it is directly discharged into the atmosphere after being treated by purification equipment, although the impact on air pollution is reduced, the waste heat is not utilized, resulting in a large amount of energy waste. [0003] At present, there are devices on the market that recover waste heat from exhaust gas, but most waste heat recovery devices are mainly for fresh air recovery, and the higher the recovery efficiency, the more complicated the structure of the device. At the same time, if the exhaust gas contains a large amount of oily fibrous substances, after the waste heat recovery device has been used for a long time, the oily substances will adhere to the surfa...
