Background
Incineration is a method of destroying some long-chain substances at high temperature to generate the simplest substances, and finally tail gas treatment is carried out by means of absorption and the like, so that the purpose of waste disposal is achieved. At present, most of the burnt materials contain a small amount of salt components or generate salt through burning, the burning is accompanied with high temperature, and most of the salt is melted at the temperature of more than 800 ℃ and is brought to a rear system along with smoke. Because the incineration of high-temperature flue gas is accompanied by a large amount of heat, the heat needs to be recovered as much as possible in order to achieve the purpose of energy conservation and value increase. Therefore, the high-temperature incinerator is connected with a waste heat boiler to recover heat in the flue gas, once the waste heat is recovered, the temperature of the flue gas can be lowered, gaseous salt or liquid salt in the flue gas can be solidified on the heat exchange tube along with the temperature reduction, and the heat exchange tube is seriously blocked to influence the use after long-time use. And once the salt is adhered to the wall of the heat tracing pipe, the salt is difficult to clean, deposited salt needs to be cleaned after the salt is used for a period of time, and a system is stopped for a long time during cleaning, so that the production is discontinuous, and the normal operation of production and processing is influenced.
