Problems solved by technology

For the viscous organic waste liquid produced in many chemical processes, it is difficult to atomize and gasify the organic waste during the incineration process, making the incineration effect not ideal. In the prior art, a large amount of oxygen is usually supplemented to promote combustion, but high temperature peroxy Combustion produces more NO x Peroxides, causing secondary pollution to the environment

Abstract

The invention provides a waste liquid incineration device and belongs to the technical field of environmental protection. The waste liquid incineration device comprises a furnace body, a burner assembly, a first flue gas circulating pipe, a second flue gas circulating pipe, a smoke exhaust system, a first furnace temperature detection device, a second furnace temperature detection device and an air bellow, wherein the air bellow is used for blowing combustion-supporting gas into the furnace body. According to the waste liquid incineration device, the position of cold flue gas introduced into the furnace body can be controlled by controlling a valve in the first flue gas circulating pipe and a valve in the second flue gas circulating pipe to be opened and closed, the flue gas entering a smoke exhaust pipe in the furnace body can return to the furnace body through the interior of the first flue gas circulating pipe and the interior of the second flue gas circulating pipe after being gradually cooled, and then the temperature in the furnace body is lowered, so that the situation that many peroxides are produced due to the fact that high-temperature oxygen-excess combustion occurs in the furnace body is prevented.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and in particular to a waste liquid incineration device. Background technique [0002] In the actual production process of the chemical industry, various industrial toxic waste liquids will be produced. Its harmless treatment has always been a very important thing in the field of environmental protection and safety. Chemical decomposition and high-temperature oxidation incineration are usually used to decompose. It is a common method to incinerate and degrade toxic waste liquid that is not suitable for chemical decomposition. The incineration method is to effectively atomize the toxic waste liquid, and then carry out high-temperature cracking in the combustion-supporting flame. . For the viscous organic waste liquid produced in many chemical processes, it is difficult to atomize and gasify the organic waste during the incineration process, making the incineration effect not ide...
