Smoke return control system of dangerous waste incinerator

Abstract

The invention relates to a smoke return control system of a dangerous waste incinerator. The smoke return control system comprises a smoke collecting assembly, a dust removing assembly and a return air assembly, and further comprises an air supplementing assembly. The smoke collecting assembly is arranged at all smoke return points and is used for collecting returned smoke. The dust removing assembly is connected with the smoke collecting assembly and is used for purifying the returned smoke. The return air assembly is connected with the dust removing assembly and used for receiving purifiedgas and is further connected with the incinerator to return the purified gas into the incinerator. The air supplementing assembly is arranged between the dust removing assembly and the return air assembly and is used for supplementing air into the system. All assemblies are connected through high-temperature-resistant pipelines. All pipelines are provided with one-way valves for controlling airflow to flow in the direction from the smoke return points to the incinerator. The smoke return control system of a dangerous waste incinerator can effectively avoid safety problems such as pit fire caused by smoke return.

Description

technical field [0001] The invention relates to the technical field of hazardous waste incinerators, in particular to a smoke return control system for hazardous waste incinerators. Background technique [0002] For hazardous waste incineration, it is generally equipped with at least 2 to 3 feeding methods. The common method is the combination of grab feeding + bucket lifting + waste liquid injection into the furnace. Grab loading and bucket lifting are generally in the material The process of pushing into the incinerator will cause the instability of the pressure in the furnace, forming a local positive pressure at the feeding part of the incinerator, and a part of the incineration flue gas will overflow along the gap of the pushing system and enter the workshop, which will affect the workshop environment. The returned smoke has not undergone any purification treatment, is toxic and harmful, has a certain temperature (80-150°C), and has a lot of unburned particles and dust,...
