A hydrogen sulfide incinerator

Abstract

The invention relates to a novel sulfuretted hydrogen incineration furnace which comprises a cavity furnace shell. An air inlet is formed in one end of the cavity furnace shell, an air outlet is formed in the other end of the cavity furnace shell, a sulfuretted hydrogen nozzle is formed in the outer end of the air inlet, a heat insulation layer is arranged on the inner wall of the cavity furnace shell, a fire retardant layer is arranged on the inner wall of the heat insulation layer, two heat storage walls are arranged in the cavity furnace shell, one heat storage wall close to the sulfuretted hydrogen nozzle is the first heat storage wall, the other heat storage wall is the second heat storage wall, the cavity furnace shell is divided into three sections by the two heat storage walls, a secondary temperature adjustment and oxygen supplementary air pipe is arranged at the position, close to the end of the first heat storage wall, between the two heat storage walls, a combustion channel flame detection device, an explosion door and a fire observation hole are arranged on the first section of the cavity furnace shell, a maintenance door is arranged on the second section of the cavity furnace shell, and a negative pressure transmitter and a smoke outlet flame detection device are arranged on the third section of the cavity furnace shell. The novel sulfuretted hydrogen incineration furnace is full in combustion, stable in flame in the furnace, safe and reliable, and saves cost.

Description

technical field [0001] The invention relates to a gas incineration device, in particular to a hydrogen sulfide incineration device. Background technique [0002] In recent years, with the sustained, stable and high-speed development of my country's economy, coal chemical industry has developed rapidly in my country. At the same time, the proportion of high-sulfur crude oil used in domestic refineries continues to increase, and a large amount of acid gas hydrogen sulfide needs to be treated in the process. . [0003] The traditional waste gas incinerator has not been individually designed for the characteristics of hydrogen sulfide incineration. The waste gas incinerator has the following shortcomings: 1. The waste gas burner does not use a semi-premixed high-efficiency burner, and the furnace is not equipped with a high-temperature zone, which is prone to unstable flames and incomplete combustion; 2. The secondary supplementary air structure of the furnace is unreasonable, a...

[0003] The traditional waste gas incinerator has not been individually designed for the characteristics of hydrogen sulfide incineration. The waste gas incinerator has the following shortcomings: 1. The waste gas burner does not use a semi-premixed high-efficiency burner, and the furnace is not equipped with a high-temperature zone, which is prone to unstable flames and incomplete combustion; 2. The secondary supplementary air structure of the furnace is unreasonable, and the furnace temperature cannot be effectively adjusted and maintained; 3. The furnace does not distinguish between high-temperature areas and low-temperature areas, and all refractory materials are made of corundum refractory materials, which are expensive ; 4. The steel plate of the furnace shell is easily corroded by sulfur dioxide condensation; 5. There is no energy-saving facility in the furnace body, and the energy consumption is relatively high
