Combustion settling chamber of electric stove fume

Abstract

The invention belongs to the technical field of separation and relates to a combustion settling chamber of electric stove fume. The combustion settling chamber has the functions of removing dust of fume, storing heat, promoting the complete combustion of CO and the like. The adopted settling chamber comprises a fume inlet, an air inlet and a fume outlet and is characterized by arranging a heat storage wall in a combustion chamber. The settling chamber can act on the electric stove fume in removing dust, storing heat and promoting the complete combustion of CO, is beneficial to the sensible heat recovery of electric stove fume, is a significant technology in the recovery of waste heat and emission reduction of smoke dust and CO for an electric steel plant, and has higher economic and social benefits, as well as stronger popularizing value.

Description

technical field [0001] The invention belongs to the technical field of separation, and relates to an electric furnace flue gas combustion settling chamber. The combustion settling chamber has the functions of flue gas dust removal, heat storage, and promotion of CO burnout. Background technique [0002] A large amount of flue gas is produced in the process of electric furnace steelmaking. Affected by the steelmaking process, the flow rate, composition and temperature of electric furnace flue gas fluctuate with time during the steelmaking cycle. In order to cool the flue gas produced by electric furnace steelmaking, water-cooled flue is usually used for cooling, which consumes a lot of water and electric energy. In order to recover the sensible heat of the electric furnace flue gas, vaporization cooling can also be used to generate steam. Due to the volatility of the electric furnace flue gas, it is difficult to set up the vaporization cooling system. [0003] The dust conte...

Problems solved by technology

At present, the combustion and settling chamber usually used adopts the method of increasing the flow area and reducing the flow rate of the flue gas to settle the smoke and dust. The combustion and settling chamber used in the current project is usually a simple cuboid structure, and the interior is a cuboid space. When the smoke flows through the combustion and settling chamber Because the flow channel area increases, the flow velocity decreases, and large particles of smoke are deposited

The dust removal effect of the traditional combustion settling chamber is poor, especially for fine particles with strong cohesiveness, and the temperature of the combustion settling chamber changes drastically with the smelting cycle o
