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 industrial production process. 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 for recovering waste heat from exhaust gas on the market, but most waste heat recovery devices for waste gas are mainly aimed at recovering fresh air, 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 is used for a long time, the oily substances adhere to ...

Examples

Embodiment Construction

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] A self-cleaning exhaust gas waste heat recovery device, combined with figure 1 As shown, it includes a rack 5, the lower part of the front end of the rack 5 is provided with an exhaust gas inlet 2, the lower part of the rear end of the rack 5 is provided with an exhaust gas outlet, and the inside of the rack 5 is provided with a split heat exchanger 14, a quick change The brush cleaning mechanism 3 and the cleaning driving mechanism, the quick brush changing cleaning mechanism 3 and the cleaning driving mechanism are connected with a PLC controller, wherein the exhaust gas inlet 2 is used to connect the high temperature exhaust gas pipeline; the exhaust gas outlet is connected to the exhaust gas discharge pipeline, so as to discharge heat exchange Exhaust gas; the split heat exchanger 14 is arranged between the exhaust gas inlet ...
