Sulfuric acid products are important chemical products, and the production process of sulfuric acid is a key factor affecting its production efficiency and product quality. With the continuous development of China’s sulfuric acid industry, the sulfur-based process for producing sulfuric acid plays an important role in current sulfuric acid manufacturing. The sulfur-based acid production process consists of three stages: sulfur melting, sulfur combustion and conversion, and drying of the final product. https://image.juhecat.com/wp-content/uploads/2020/06/WechatIMG722.png?x-oss-process=image%2Fformat,webp The sulfur melting process mainly involves feeding liquid sulfur into the sulfur combustion furnace so that it can burn. In practical operations, to ensure that sulfur remains in a molten state at all times, steam heating tubes are installed in various components of the sulfur incineration furnace, such as the auxiliary tanks, rapid melting tanks, and distillation tanks. Their function is to use high-temperature steam to heat the sulfur, thereby keeping it at a high temperature and ensuring it stays in a molten state. Additionally, a filter aid pump needs to be installed inside the filter aid tank; with the help of this pump, the filter aid can be effectively pre-coated in the sulfur filter. II. Sulfur combustion conversion: This process involves using a sulfur spray gun to turn sulfur into a liquid state, thereby enabling its atomization. The liquid sulfur obtained in the previous step is atomized using the sulfur gun, and then it is burned in a sulfur combustion furnace. The air required for this combustion process must be filtered through an air filtration device, and after filtration it is pressurized and dried before being fed into the combustion furnace to create the conditions necessary for the burning of sulfur. III. Drying of the finished product: For the air required in the above two processes, by applying filtration, pressurization, and drying treatments, the moisture present in the air can be essentially completely removed. The resulting dry air is passed through a demister to remove the acid mist; thereafter, the gas obtained after the removal of the acid mist is fed into an incinerator for combustion. The gas produced as a result of this combustion can be sent through heat recovery equipment and then into a converter for further processing. After the conversion is completed, part of the resulting conversion gas can be fed into the nicotinic acid tower, while another part can be fed into the first absorption tower, where drying takes place. For the gas in the first absorption tower, after passing through the demisting heat exchanger, it can be sent to the converter for secondary conversion, and the process in the first absorption tower must be repeated again. Through two conversion and drying steps, the finished sulfuric acid can be discharged from the outlet of the dry acid circulation pump, cooled in a cooling system, and then stored. The advantages of the sulfuric acid process are its relatively short processing time, low costs, and minimal pollution generated. It is now widely used and holds great value.
