Abstract

The invention discloses a sulfur recovery combustion furnace, and belongs to the technical field of chemical equipment. The sulfur recovery combustion furnace comprises a combustion furnace body, a gas burner, an acid air gun, an ignition gun, swirl vanes, a mixing chamber and a combustion chamber, wherein the gas burner penetrates through the middle of the acid gas gun and is coaxially arranged with the acid gas gun; an outlet of the gas burner and an outlet of the acid gas gun are both located in the mixing chamber, and the mixing chamber communicates with the combustion chamber; a fixed bracket is arranged between the outlet end of the gas burner and the outlet end of the acid gas gun, and two ends of the fixed bracket are fixed on the gas burner and the acid gas gun respectively; the swirl vanes are arranged inside the acid gas gun and sleeves the gas burner, and are fixed on the fixed bracket, and the ignition end of the ignition gun is arranged in the combustion chamber. The sulfur recovery combustion furnace can keep running for a long period of time without reduced sulfur recovery efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical equipment, in particular to a sulfur recovery combustion furnace. 【Background technique】 [0002] With the continuous development of my country's petrochemical industry, various chemical equipment and chemical instruments are used in the actual production process. Among them, the combustion furnace is often used in the chemical production process related to sulfur recovery. In the existing combustion furnace, gas is ejected at high speed from the gas gun, and acid gas is ejected at high speed from the acid gas gun. The ejected gas and acid gas are uniformly mixed in the mixing chamber, and then enter the combustion chamber for combustion. However, existing combustion furnaces often have the phenomenon of furnace head vibration. After long-term use, the swirl blades will be cracked and damaged due to the vibration of the furnace head, and the outlet end of the acid air gun will fall, causing the...
