Technical Field
The utility model relates to a carbon black reacting furnace, concretely relates to combustion chamber of carbon black reacting furnace.
Background
Oil furnace carbon black is produced by incomplete combustion and cracking of hydrocarbon compounds. The reaction device for producing the carbon black is a reaction furnace and mainly comprises a combustion section, a throat section, a reaction section, a quenching section and a gasification retention section. The fuel is burnt in the burning section to improve the energy for the carbon black cracking reaction, the throat section is a raw material injection section, the reaction section is an area of incomplete burning and cracking of the carbon black, the quenching section stops the carbon black production reaction through water (the carbon black is subjected to surface oxidation reaction in the stage), and the gasification retention section is a carbon black smoke forming area.
The prior art combustion reaction is achieved by: air enters the gas-air mixer along the axial direction of the reaction furnace through the air distributor, coal gas enters the gas-air mixer along the radial direction of the reaction furnace, the air and the coal gas are mixed in the gas-air mixer, and the mixed gas is diffused to the combustion section for combustion reaction. When the gas supply is unstable, a reduction load production is required, which results in an increase in the production of defective products.

Detailed Description
The invention will be further described with reference to the accompanying drawings and a specific embodiment.
As shown in FIG. 1, a combustion chamber of a carbon black reaction furnace includes an air distributor 100, a mixer 200, and a combustion section 300.
The air distributor 100 has an air inlet 101 and an air outlet, wherein the air inlet 101 is radially arranged and the air outlet is axially arranged, and the air outlet is in communication with the mixer 200. The air distributor 100 is further provided with an axial fuel oil gun sheath tube 102, one end of the fuel oil gun sheath tube 102 is located outside the air distributor 100, and the other end of the fuel oil gun sheath tube extends into the mixer 200.
The mixer 200 has eight gas inlets 201, and the eight gas inlets 201 are radially arranged and uniformly distributed, i.e. the included angle between two adjacent gas inlets 201 is 45 ° (as shown in fig. 2).
The front end of the combustion section 300 is communicated with the mixer 200, the rear end is provided with a contraction part 302, and the side wall of the contraction part 302 is provided with a connecting flange 303. The inner wall of the combustion section 300 is provided with refractory bricks 301.
The working principle of the combustion chamber of the carbon black reaction furnace is as follows: high-temperature air enters the air distributor 100 from the air inlet 101 and then enters the mixer 200 from the axial air outlet, and fuel gas enters the mixer 200 from the radial fuel gas inlet 201; the air and the fuel gas are diffused to the combustion section 300 to perform a combustion reaction. When fuel oil is needed to be used as fuel, the fuel oil gun is inserted into the fuel oil gun protective sleeve 102, the fuel oil is atomized and then sprayed into the mixer 200 to be mixed with air, and then the fuel oil is diffused to the combustion section 300 to carry out combustion reaction, so that energy is provided for carbon black cracking reaction, and multiple fuels can be used simultaneously. When the gas supply is unstable, part or all of the fuel oil can be used as fuel, so that the stable quality of carbon black production is ensured, and the output of unqualified products is reduced.
