In the traditional desulphurisation technology of sulphur dioxide removal, limestone, ammonia and so on are usually used as absorbents to achieve the purpose of desulphurisation through chemical reaction with sulphide. However, these traditional technologies have problems such as high absorbent consumption, serious equipment corrosion, and secondary pollution. In order to overcome these problems, the engineers of Yizhi Technology began to explore new desulphurisation technologies, and finally successfully developed the ionic liquid desulphurisation process technology.

Iron and steel metallurgy industry is an important part of the national economy, providing an indispensable material foundation for the country and people's life. However, with the continuous growth of iron and steel production, the problem of exhaust gas emission has become increasingly serious. Exhaust gases generated during the steel production process cause a certain degree of pollution to the atmospheric environment. Among them, nitrogen oxides (NOx) is one of the main pollutants, which is harmful to human health and ecological environment. Therefore, the treatment of waste gas in the iron and steel metallurgy industry is particularly important. Flue gas denitrification technology is one of the effective means to deal with NOx in iron and steel metallurgy exhaust gas, selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) are currently the mainstream of the two denitrification technologies, which play a pivotal role in iron and steel metallurgy industry e

Vacuum technology plays a vital role in modern industry and technology. Centrifugal vacuum pumps, as an important fluid transfer equipment, are widely used in many fields such as scientific research, industry and medical treatment. As a technology leader in this field, Chengdu Yizhi Technology Co., Ltd. has been committed to researching, developing and promoting high-efficiency centrifugal vacuum pump technology, which has brought significant technological progress and economic benefits to various industries by virtue of its excellent performance and efficiency.
