The largest domestic air compressor unit was born in Shenyang

The reporter learned from the Shenyang Blower Group on June 8 that the company's H596 compressor unit, a large-scale 52,000 air separation unit developed and produced by the company, has been successfully tested on medium and low-pressure cylinders. The unit is currently the country's largest air-pressure equipment, marking the development of a large drum compressor unit has reached a new height.

The air compressor unit is the key auxiliary equipment of the air separation unit, and the air separation unit is an important auxiliary equipment widely used in oil refining, ethylene, chemical fertilizer, coal chemical industry, metallurgy and other industries. At present, the main performance parameters and technical indicators of domestic 40,000 to 60,000 class air separation plants have been synchronized with foreign countries. With the cooling of the domestic iron and steel industry in the past two years, the rapidly growing chemical industry will become the largest user of air separation equipment and industrial gases. The H596 unit developed by Shengu was a large-scale air compressor unit for the production of 52,000 air separation units of Zhongyuan Dahua Company in Henan Province. It was one of the major “communist project” projects last year and was also the cross-year of Shengu Turbine Company. The key product. The medium and low pressure cylinders of this unit are more than 5 meters high and 25 meters long. The diameter of the rotor is 1.20 meters. The single cylinder has a mass of more than 50 tons. The large volume, the large number of key technologies, and the difficulties in design and manufacture have all created localization. The most developed press. It is reported that this air separation unit will be shipped to the Zhongyuan Dahua Shell Pulverized Coal Gasification Process with an annual capacity of 500,000 tons of methanol plant construction site.

At present, there are many companies that produce air compressors in China, but companies that can design and manufacture compressors for use in large-scale air separation plants are only Shengu and Shaanxi Drum. According to Liao Bin, Secretary General of the Gas Separation Equipment Branch of the China General Machinery Industry Association, China's largest domestic air compressor unit that has already achieved industrial application is an auxiliary compressor for 48,000 air separation units, technically more than 50,000 units There is still a certain degree of difficulty, and generally still need to be imported. This is mainly due to the fact that once the air separation unit exceeds 30,000, the design ideas and industrial processes of the supporting air compressors have undergone qualitative changes. The larger the scale, the greater the technical requirements and the difficulty. At present, domestic air compressors still need improvement in terms of efficiency and reliability. Therefore, Shen Drum developed the H596 unit and its significance is very significant.
