5000m ^ 3 / h of high purity nitrogen inflation equipment Machine
h5s) = 0.7473. As the deviation from the design point running more,[link widoczny dla zalogowanych], and therefore less efficient. The following based on their performance curve (Figure 3) the efficiency correction. First calculation: speed impeller inlet expansion U. : N7c. / 60 cryogenic technology in 2005 No. 6 CryogenicTechnologyNo62005'21 'design and manufacture of Li Jiazhong: 5000m3 / h of high purity nitrogen equipment, expansion of Machine: 9440 × Ji × 0.17/60: 84.0271m / s, the ideal isentropic Speed C. = 91.5 = 91.5 × Li = 166.5029m / s, then U = 0.505. Performance curve from the expander Richard: knock = 0.853. So knock s: 0.7473/0.853''opt0.876, the results of the isentropic efficiency than the design point of knocking. = 0.84 higher than the nearly 4%. From the above analysis of operating parameters and the results show that: ① the expander is efficient and stable operation; ② fan adjustment and reliable performance. Figure 3 expander performance curve. More features than a knock. A relative efficiency of new product development HangYang 5 Following BOC Taiwan UMC 5000m / h high-purity nitrogen equipment successfully put into production, has signed a joint-stock companies in Zhejiang Glass 3000m3 / h of high purity nitrogen equipment and Hainan Shihua 8000m3 / h of high purity nitrogen equipment supply contracts, a unit is being set for Xinjiang ※ ※ 30000m / h high-purity nitrogen equipment to do technology demonstration program. 8000m3 / h,[link widoczny dla zalogowanych], and 30000m / h high-purity nitrogen equipment technical parameters in Table 3. It should be said, high-purity nitrogen equipment market prospects. In high-purity nitrogen equipment to large-scale development, the expansion is too large, too large volume flow of imports, supporting a single expander is sometimes difficult to achieve. Table 38000m. / H and 30000m3 / h high-purity nitrogen equipment for the expansion of the machine parameters Parameter SO00 ~ / h high-purity nitrogen equipment 30000 / h high-purity nitrogen equipment flow / (m3 / h) l650049720 inlet pressure / MPa (A) 0.5220, 385 inlet temperature / K12112o outlet pressure / MPa (A) O, l360, 127 Brake Booster Fan Number of units recommended by supporting a single or two single or twenty-one three Conclusion 5000m / h high-purity nitrogen expander device The successful development of such expansion for the Hang oxygen machine design and manufacturing experience accumulated, the Hang oxygen equipment market to develop high-purity nitrogen basis, the majority of users at the same time bring considerable economic benefits. Of course, due to experimental conditions, and many other factors, the author's understanding of such expander shortcomings,[link widoczny dla zalogowanych], the experts also urge that assessment to be corrected. ※ Tianke large shares of Shenhua Coal Liquefaction winning PSA-H devices June 22, 2005, Sichuan Tianyi Science & Technology Co. I of the hydrogen pressure swing adsorption gas separation technologies, Shenhua Group winning international bid. This is the world's largest PSA. H: industrial equipment, mark the PSA technology in China has reached world advanced level. Shenhua Group The project is an investment of 24.5 billion, including coal liquefaction, coal, hydrogen, solvent hydrogenation, hydrogenation of modification of 14 sets of main production unit, put into operation in 2007,[link widoczny dla zalogowanych], annual production of gasoline, diesel and other oil products 3.2 million t. PSA hydrogen purification process of hydrogen contained in coal, coal preparation plant will provide partial oxidation of coal by the method into synthesis gas, then after transformation, the hydrogen pressure swing adsorption and other processed products, processing gas is 340000m / h, hydrogen production To 280000m / h, the purity of 99.9%. China has been running the 'PSA's largest hydrogen plant hydrogen production capacity of 75000m3 / h, the foreign KTI gas in Canada was designed to deal with 236000m ~ / h of the PSA hydrogen plant is currently under construction investment. Division shares with the domestic-day research and development of professional engineering and technical strongest PSA system capability, technology, engineering development, special adsorbents, special valves and automatic control have their own strengths, the formation of the independent intellectual property rights. Section 1994, shares the first day of large-scale PSA in Zhenhai Refinery Hydrogen Production Unit in the successful international competitive bidding,[link widoczny dla zalogowanych], and implementation of domestic, foreign companies from the end of large-scale PSA installations in the area of domestic monopoly, and gradually replace imports.
