Description
Technical Field
The invention relates to the field of waste heat utilization, in particular to a tail gas waste heat utilization device with a carbon black removing function.
Background
At present, the recovery of the waste heat of various heat engine tail gases is realized by various heat exchangers, so that the heat of the tail gases can be increased, and the energy utilization efficiency is also improved. With the increase of the service time, the heat exchanger at the tail end of the tail gas has a layer of thick carbon on the surface of the tail gas due to the smoke dust in the tail gas, so that the heat exchange efficiency is greatly reduced. And some solid particles (carbon black) contained in the exhaust gas can adhere to the inner wall of the pipeline, so that the carbon black can block the exhaust pipeline. The existing solution is that the carbon removal can not be achieved only by washing away some surface floating dust through disassembly and cleaning; secondly, spraying some chemical reagents, but the chemical reagents can corrode equipment while removing carbon; and thirdly, the tail gas is prevented from being crystallized and changed into solid in the pipeline by adjusting the descending amplitude of the temperature of the tail gas.
