The invention relates to the technical field of sulfuric acid industry, and particularly relates to a heat supply system and application thereof in sulfuric acid production. The heat supply system is used for supplying heat to a liquid sulfur storage tank and a liquid sulfur transportation pipeline by adopting a boiler drum, relieving the problem that sulfur in the liquid sulfur storage tank and the liquid sulfur transportation pipeline is easily solidified when a sulfuric acid system is maintained in a short time and realizing resource recycling and energy conservation by sufficiently utilizing heat energy of steam in the boiler drum, and is scientific and reasonable in design, simple and feasible. The application of the heat supply system in sulfuric acid production has the advantages of simple and feasible operation and energy conservation, steam in the boiler drum can be used for constantly supplying heat for liquid sulfur for 7-9 hours, production cost of enterprises can be reduced, and energy conservation and emission reduction can be achieved.
Description
technical field [0001] The invention relates to the technical field of sulfuric acid industry, in particular to a heating system and its application in sulfuric acid production. Background technique [0002] Sulfuric acid is one of the most important products in the chemical industry. It is known as the "mother of the chemical industry". The output of sulfuric acid marks the degree of industrial development of a country to a certain extent. Sulfuric acid has a wide range of uses, mainly in the fields of chemical fertilizers, pesticides, metallurgy, dyes, and medicine. The production method of sulfuric acid is divided into pyrite, sulfur and smelting furnace gas according to its raw materials. Compared with sulfuric acid production from pyrite, the sulfuric acid production process has the advantages of simple process, low cost, and less environmental pollution during the production process, and is widely used. [0003] Sulfur acid production includes sulfur melting process,...
