Problems solved by technology

[0005] However, the flue gas collecting device disclosed in this patent collects the flue gas from all the collecting hoppers at the same time during the process of cleaning the flue dust and collecting the flue gas, which will cause a large amount of flue dust to be collected by the suction pipe at the same time, resulting in the suction of the suction pipe Insufficient, there is a fault that smoke and dust are accumulated in the exhaust pipe

Abstract

The invention relates to the technical field of pyrometallurgical melting treatment and processing of hazardous wastes, in particular to a reduction smelting furnace for high-temperature melting of waste sludge. The reduction smelting furnace comprises a plurality of arranged reduction smelting furnace bodies and a flue gas collecting device, wherein the flue gas collecting device comprises a collecting main body, a wind chamber, a suction pipe, a first collecting pipe, a second collecting pipe and a fourth collecting pipe; the diameters of the first collecting pipe, the second collecting pipe, a third collecting pipe and the fourth collecting pipe are gradually reduced in the axial direction of the first collecting pipe; a collecting hopper communicating through a communicating pipe is arranged on each of the first collecting pipe, the second collecting pipe, the third collecting pipe and the fourth collecting pipe; a cleaning wiper which is rotationally arranged is arranged in each collecting hopper; and a driving assembly for driving the corresponding cleaning wiper to rotate and a valve assembly for controlling connection and disconnection of the corresponding communicating pipe are arranged at the top of each collecting hopper.

Description

technical field [0001] The invention relates to the technical field of pyromelting treatment and processing of hazardous waste, in particular to a reduction smelting furnace for high-temperature melting of waste sludge. Background technique [0002] The pyromelting processing technology of hazardous waste is to firstly crush and screen the raw materials according to different components, and then make them into a certain particle size through a granulator, then send them to a deep drying furnace for deep drying, and finally send the block sintered material to a reduction melting furnace for melting. The sintered powder is put into the smelting furnace for smelting after being dried in brick making. [0003] In the reduction smelting process, a large amount of soot and tail gas will be produced, which needs to be treated, and the choice of flue gas treatment mainly depends on the conditions of the original flue gas, the supply conditions of the absorbent and the geographical ...
