Oxygen-enriched acid gas incinerator burner and working method thereof

A working method of an oxygen-enriched acid gas incinerator burner comprising

• a propulsion mechanism, a pure oxygen spray gun, an acid gas spray gun, a fuel gas spray gun and a housing,
• wherein:
• a refractory lining is arranged on an inner wall of the housing;
• an inner cavity is formed in an inner center of the housing at an end of the housing;
• a rear part of the inner cavity is connected to a throat opening;
• the pure oxygen spray gun, the acid gas spray gun, and the fuel gas spray gun are arranged in a pipe-in pipe structure from outside to inside;
• a rear part of the pure oxygen spray gun is fixed within the inner cavity through a flange at an outer end of the housing;
• a front part of the acid gas spray gun is fixed through a flange at an outer end of the pure oxygen spray gun;
• a front part of the fuel gas spray gun is fixed through a flange at an outer end of the acid gas spray gun;
• a combustion-supporting air inlet is formed at a position, corresponding to the throat opening, on the housing;
• a lower part of the combustion-supporting air inlet is communicated with a gas collection chamber;
• the gas collection chamber is formed by building bricks made of a zirconium-containing corundum material, is arranged along a circumferential surface of the throat opening, and is arranged in the refractory lining;
• a circle of diversion holes communicated with the throat opening are formed in the gas collection chamber;
• and the diversion holes are in a right-handed rotation arrangement when looked from an upstream direction, and the diversion holes are uniformly distributed along a circumferential direction of the gas collection chamber;
• wherein, a rear end of the fuel gas spray gun is connected with a ball valve and a high-energy igniter in sequence, and the propulsion mechanism is provided on the high-energy igniter, and
• wherein external mixed diffusion combustion with excess oxygen is realized by introducing combustion-supporting air according to a series of steps comprising:
• introducing acid gas through the acid gas inlet, introducing fuel gas through the fuel gas inlet, introducing combustion-supporting air through the combustion-supporting air inlet, mixing the combustion-supporting air with the fuel gas and the acid gas through the circle of diversion holes in the gas collection chamber, and spraying mixed gas into the combustion chamber through the throat opening.
