一种对含有硫化氢的酸性气体进行脱硫并回收硫的方法,依次包括如下步骤:将酸性气体通入燃烧炉中,与从另一管道通入的空气混合进行燃烧反应,在燃烧炉中反应后的气体进入到降温器中降温至230~250℃,降温后液态硫从液体出口分离,而在燃烧炉中的混合气体进入催化剂反应器,在催化剂反应器中使硫化氢与二氧化硫之间反应生成硫与水,生成的液态硫从催化剂反应器液体出口分离;催化剂反应器中的混合气体进入至加氢反应器中,在加氢反应器中的二氧化硫与氢气反应;加氢反应器
A method for desulfurizing and recovering sulfur acid gas containing hydrogen sulfide comprises the following steps in sequence: passing an acid gas into a combustion furnace, mixing with air passing through another pipe for combustion reaction, and reacting in a combustion furnace After the gas into the desuperheater to cool to 230 ~ 250 ℃, after cooling the liquid sulfur from the liquid outlet separation, and the mixed gas in the combustion furnace into the catalyst reactor in the catalyst reactor so that the reaction between hydrogen sulfide and sulfur dioxide Generating sulfur and water, and the generated liquid sulfur is separated from the liquid outlet of the catalyst reactor; the mixed gas in the catalyst reactor enters the hydrogenation reactor and the sulfur dioxide in the hydrogenation reactor reacts with hydrogen; and the hydrogenation reactor
