Integrated incineration equipment for low-calorific-value sulfur-containing gas

The utility model relates to integrated incineration equipment for low-heating-value sulfur-containing gas. The integrated incineration equipment comprises a shell and an incineration cavity. The shell comprises an outer-layer steel plate, a middle-layer heat preservation layer and an inner-layer fire-resistant layer; the incineration cavity is uninterruptedly divided into a combustion chamber, a reaction chamber and a heat exchange chamber through built-in fireproof walls; the top of the combustion chamber is provided with a gas burner, a sulfur-containing gas inlet and a sulfur-containing gas ventilation opening which penetrate through the shell. A heat exchanger penetrating through the shell is arranged on the side wall of the heat exchange chamber; the low-calorific-value sulfur-containing gas is incinerated in the combustion chamber through a gas burner to form flue gas, and the flue gas flows into the reaction chamber from the bottom of the combustion chamber and then flows into the heat exchange chambe
