Problems solved by technology
The wet dedusting technology is relatively mature, but the investment cost is high, the maintenance cost is high, and the emission pollution is high
[0006] The traditional waste heat power generation system converts thermal energy into electrical energy, and then converts electrical energy into kinetic energy. During the conversion process, energy will be lost, which reduces the utilization rate of thermal energy and increases the cost of the enterprise.

The dust removal and two-medium waste heat generation system is simple, compact and reasonable in structure; by adoption of two-medium waste heat generation, the waste heat utilization rate is high; the service life of a dust collector is greatly prolonged; the environmental pollution is less; the investment cost is low; and the energy loss is reduced.
Description
technical field [0001] The invention relates to an argon-oxygen decarburization converter dust removal and dual-medium waste heat power generation system, belonging to the technical field of converter waste heat utilization. Background technique [0002] A large amount of waste heat is generated in industrial production. Especially in iron and steel, nonferrous metals, chemical industry, cement, building materials, petroleum and petrochemical, light industry, coal and other industries, these waste heat resources account for about 17%~67% of their total fuel consumption, and the recovery rate of waste heat materials can reach 60%. . [0003] At present, the utilization ratio of waste heat resources in my country is low. According to statistics, the total amount of waste heat generated in the industrial production of large and medium-sized enterprises in my country is 8.44GJ, accounting for about 37% of energy consumption, and the sensible heat carried by its final products ...
