Diffuse type sulfur burner

Abstract

The invention provides a diffuse type sulfur burner, comprising a burner body, wherein a liquid sulfur spray gun and an air inlet pipe are both arranged at the entrance of the burner body. The burnerbody comprises a combustion chamber front section, a reducing joint chamber and a combustion chamber rear section which are connected in sequence; both the combustion chamber front section and the combustion chamber rear section are cylinders, the inside diameter of the combustion chamber front section is smaller than that of the combustion chamber rear section, a small-opening end of the reducingjoint chamber is connected with the combustion chamber front section, and a big-opening end of the reducing joint chamber is connected with the combustion chamber rear section; the burner body is provided with a plurality of temperature measurement points and a sight glass, and the sight glass is particularly arranged on the combustion chamber front section, of the burner body; a baffling barrierwall is arranged at the combustion chamber rear section. The diffuse type sulfur burner is simple in structure and easy to mount, saves consumables, realizes full sulfur combustion, reduces production energy consumption and greatly improves sulfur combustion efficiency; the stability of the whole diffuse type sulfur burner is also improved.

Description

【Technical field】 [0001] The invention relates to a diffusion type sulfur burning furnace. 【Background technique】 [0002] In the process of sulfuric acid production, the liquid sulfur is sprayed out after being atomized by a sulfur lance, and the dry air is sent into the sulfur incinerator by an air blower to mix with the liquid sulfur atomized by a sulfur lance, and the Oxygen and sulfur vapor are burned, and the reaction generates sulfur dioxide flue gas to participate in the subsequent reaction and absorption of the entire process. [0003] The sulfur incinerator is the core equipment in the sulfuric acid plant. It is composed of steel shells lined with insulation bricks and refractory bricks. The temperature in the furnace is as high as 1100°C during normal operation. Due to the high temperature of the sulfur incinerator, it is the key equipment for sulfur combustion to generate sulfur dioxide. , so the safe operation of the sulfur incinerator is related to the safety ...

AI Technical Summary

Problems solved by technology

The traditional sulfur incinerator is a horizontal cylindrical or vertical cylindrical structure, which has many problems such as high material consumption, difficult installation, and poor stability.

[0004] In addition, during the combustion of sulfur in the sulfur furnace, although the atomized sulfur can burn quickly, there will still be incompletely burned sulfur in the furnace gas near the liquid sulfur spray gun, and incompletely burned sulfur It will be deposited in the equipment pipeline and cause blockage, which will not only increase the system resistance and affect the production capacity of the device, but also increase energy consumption
