China's first set of thousands of air compressor in shen drum successful commissioning

On August 23, from shenyang blower group co., LTD. (hereinafter referred to as "shen drum group) independent research and development of China's first set of hundreds of air separation unit compressor in yingkou successful commissioning test base, shen drum marks in large air separation devices form a complete set of key equipment in our country among the world's highest, broke the barriers to foreign core technology monopoly, shen drum become after Siemens, mann turbine, third world can produce the products.

National energy bureau chief economist li zhi, China machinery industry federation chief engineer SuiYongBin, drum group chairman shen yong-qiang su, user representatives jian-hua yan, general manager of hangzhou steam turbine co., shenhua ningxia coal group party secretary Zhang Zuoli etc. Witness the moment.

Has the milestone significance

Shen drum group successfully developed comply to the level of air compressor, implement replace imported in to fill the domestic blank, at the same time, also meet the energy demand for large fluid machinery in our country, has a significant milestone. Li zhi said in an interview with China's industrial press, our country is energy superpower, so our country energy engineering construction scale is also the most of the world. Large petrochemical industry, coal chemical projects need large air separation devices, so the air separation unit and air separation devices configured compressor equipment demand is very big, so the device can do, only two companies before technology will not transfer to us, and the price is expensive, it should be said that shen drum group set ten years trying to do this project is actually successful development. "Innovation, this time to say, I think is under the guidance of the state, combine major projects and major technical equipment innovation, relying on major projects, major users, to promote the localization of important engineering technology. 'much starker choices-and graver consequences-in during such a major project demonstration, in promoting major engineering equipment is still the gripper."

Li zhi, points out that at present, coal accounted for more than 70% of the proportion of the energy consumption in our country, the next step, we will adjust the structure in the energy field, on the one hand, as far as possible the control of coal consumption, on the other hand is to clean and efficient use of existing coal. And make coal deep processing is actually to clean utilization of coal is a very effective approach. This unit is to provide power for the whole coal chemical process equipment "heart". At present, the national coal chemical projects under construction and to be approved, be badly in need of a large number of hundreds of level of air compressor, localization, the unit can not only for the country and the user to save a lot of investment, more related to national economic security.

Create multiple shen drum

China industry news reporter learned during the interview, shen drum group is the general industry in our country and fan industry leading enterprises, carrying out for China's petrochemical industry, coal chemical industry, electric power, metallurgical industries such as major projects to provide the task of localization of high-end equipment. To break the situation of large air separation equipment abroad long-term monopoly, for decades, shen drum has been committed to the experimental study of the unit, through a lot of research and testing, groping and accumulated the first-hand data and experience, has completed the uniaxial 52000 air compressor unit, multi-axis 42000 units, more than 50000 axial pressurization unit of development and to the market, thousands of air compressor to undertake the development of laid a foundation.

In December 2013, shen drum group and shenhua ningxia coal group signed "4 million tons/year coal indirect liquefaction project hundreds of air separation unit compressor set used in" supply contract. Project implementation process, shen drum group, break the routine, careful planning, every breakthrough in the conventional manufacturing cycle, 14 months abroad in just 12 months to create China's first with independent intellectual property rights of air separation unit equipment, for the first time hundreds of air separation plant unit localization grade, for the rise of "Chinese city" wrote a dense.

SuiYongBin in an interview with China industry news reporters, said: "thousands of air separation unit localization, has long been China's manufacturing industry of the Chinese dream. Shenhua ningxia coal project for us to achieve this dream, provides the competing with foreign advanced device challenge."

As the core equipment of coal chemical industry, a set of 4 million tons/year coal indirect liquefaction oil system equipment, need 12 sets of hundreds of air separation (100000 nm3 / h oxygen) form a complete set of air compressor. By 2015, the state has approved and to approve the coal chemical projects, need such a size more than 70 sets of air compressor.

Shenhua ningxia coal coal project battalion commander Cai Lihong of China industry news reporters that shenhua ningxia coal project is the national 12th five-year demonstration project, the project investment of 60 billion yuan, is the world's largest coal chemical projects, need 12 sets of air separation unit, corresponding 12 sets of compressor, 11 sets of compressor turbine by the German man make grinders, we come up with a set of let shen drum do localization of compressor. This time, thousands of air compressor in shen drum successful commissioning, marked the shen drum air compressor technology reached the international first-class level.

Cai Lihong admitted that the enterprise needs to avoid risk, because the coal chemical industry is the first device security, stability, the heart of the compressor is device, once there is a problem to smooth operation of the device, the $60 billion project will be of great risk, the economic benefits of the trial is successful, not only brings us a confidence, but also has a triple meaning to our construction projects. It is greatly save the project investment. 2 it is to shorten the production cycle, the past abroad compressor to availability in 21 ~ 25 months, shen drum compressor supply just 17 ~ 18 months. 3 it is after-sales service more convenient.

Yong-qiang su, said shen drum stand in the Angle of the state and national industry development, investment 700 million yuan construction test base; Investment more than 4000 ten thousand yuan to scientific research; To invest 100 million yuan to unit test; Investment of more than 2000 ten thousand yuan to experiment with steam and electricity; Investment of more than 3000 ten thousand yuan to test equipment. Practice proves that this investment is necessary and timely. The unit in addition to achieve high reliability, high stability, high efficiency, low energy consumption and other targets, indicators, most of the drum has also created a lot of shen: unit (70000 kw), the largest power structure size biggest (more than 30 meters long and 15 meters high), the heaviest unit (478 tons), unit structure, the most complex (axial + centrifugal, uniaxial + multi-axis), the highest unit most r&d, manufacture cost, experiment the longest, most species.

Yong-qiang su said the success of the project for shen drum for significant new development project in the future to increase the bottom spirit and ability. Future shen drum group will continue to adhere to the development of high-end equipment, the equipment as own duty, China implemented "development of high-end equipment, to the service transformation, to the engineering of complete sets of transformation, expand the overseas market, to meet the new market development transformation" five shift, continue to deepen the communication and cooperation with the customers, in the new journey of the northeast China bigger strides, make greater achievements.
