Abstract

The application discloses a tail gas incineration technique, which is used for incinerating sulfur-containing tail gas from a sulfur recovery unit; the technique includes treatment steps of incinerating the sulfur-containing tail gas; performing heat exchange on the smoke gas generated by incineration and sulfur-containing tail gas to be incinerated so as to heat tail gas, and cooling smoke gas; delivering the tail gas heated by heat exchange to incinerate. The application further discloses a tail gas incineration device and a tail gas incineration furnace for realizing the technique. According to the invention, the tail gas is heated through the heat exchange between the high temperature smoke gas and the low temperature smoke gas to be incinerated, and the smoke gas is cooled, thus the incineration temperature can be increased; the tail gas can be sufficiently incinerated, and discharged as standard.

Description

technical field [0001] The invention relates to a tail gas incineration process and equipment for sulfur-containing tail gas, in particular to a tail gas incineration process, tail gas incineration equipment and a tail gas incinerator for the tail gas of a sulfur recovery device. Background technique [0002] The tail gas of the sulfur recovery unit contains a certain amount of hydrogen sulfide and organic sulfide. In order to meet the pollutant emission standards, it must be incinerated before it can be discharged. Due to the low combustible components in the exhaust gas, fuel must be supplemented to complete combustion, and the hydrogen sulfide in the exhaust gas is oxidized to sulfur dioxide. The current process method is as follows: the purified tail gas from the top of the tail gas absorption tower is sent to the tail gas incinerator for incineration, and the furnace temperature is generally controlled by the fuel gas flow rate at about 600 °C; the incinerator blower is...
