Description

TECHNICAL FIELD

[0002] Incinerator is usually used in waste treatment system, waste is put in and burns, and high-temperature flue gas is generated. Incinerator usually needs to combine the function of purification tower, can purify high-temperature flue gas by water spray after incineration, remove particulate matter and harmful gas in flue gas, and realize the purification of flue gas. Because the flue gas generated by incinerator has high temperature, it usually has heat recovery function, for example, Chinese patent document CN202223129053.2 discloses a hazardous waste incinerator system flue gas white smoke removal device, which comprises an air inlet pipe, a material collecting assembly, a gas conveying pipe, a purification assembly, a heat exchange box, a heat exchange pipe, a water inlet pipe, a water outlet pipe, a fan, a check valve and an electric control cabinet. In use, the heat exchange box and the heat exchange pipe are used to recover the heat energy of high-temperature flue gas. The cooled flue gas enters the material collecting box through the air inlet pipe. The blocking plate blocks the particulate material in the flue gas. The particulate material falls into the material collecting box under the action of gravity, realizing the collection of particulate material and avoiding the entry of particulate material into the purification assembly, improving the use effect of the white smoke removal device. The guide ring guides the particulate material to fall into the material collecting box. The setting of the purification assembly purifies the flue gas with lime water. The circulating pump is connected to the liquid outlet pipe through the pipeline and the circulating pipe. The lime water is sprayed by the liquid spraying head to further purify the rising flue gas and remove sulfides in the flue gas. The above-mentioned patent realizes heat energy recovery and purification process in flue gas at the same time. However, the heat exchange box for recovering heat energy is a separate box. A gas conveying pipeline needs to be additionally arranged between the incinerator and the heat exchange box.
