Atlas Copco screw blowers help Tianjin Sinopec achieve clean and low-carbon developmentOne of the sources of pollution in smoggy days: excessive coal emissions! The clean development of coal-fired power is an arduous task that cannot be delayed. Since 2015, my country's coal-fired power plants plan to be fully equipped with dust removal, desulfurization, and denitrification devices to meet ultra-low emission standards, and to build the world's largest clean and efficient coal power system by 2020. Atlas Copco's screw blowers also play an important role in the desulfurization process of coal-fired power plants. The following is the actual application of ZS screw blowers in Tianjin Sinopec Thermal Power Plant. Sinopec Tianjin Branch (hereinafter referred to as Tianjin Sinopec) was established on December 28, 1983 and is located in Tianjin Binhai New Area, covering an area of 14 square kilometers. The annual processing capacity is 12.5 million tons/year, the ethylene production capacity is 1.2 million tons/year, and the subordinate thermal power plant, the third phase includes 220 tons/hour, 410 tons/hour and 465 tons/hour steam boilers. Using the most widely used wet desulfurization technology in the world, limestone is made into lime slurry, which is sprayed and atomized in the absorption tower to make it contact with the flue gas, so as to achieve the purpose of desulfurization. This process requires a blower to transport such as air to achieve oxidative desulfurization reaction. The desulfurization project is currently the environmental protection project with the highest one-time investment and continuous operation investment in the construction of thermal power plants. The selection of equipment will directly affect the economy and technology of the entire project investment. As a key large-scale equipment in the entire desulfurization operation, whether the selection of the oxidation fan is reasonable is directly related to the investment and operation effect of the entire project. Therefore, Tianjin Sinopec made a careful and rigorous comparison when choosing a blower supplier. Among the two final locked suppliers, Atlas Copco's ZS screw blower stands out from the Roots blower due to its many advantages such as fan efficiency and low noise. Atlas Copco ZS series blowers are manufactured to the highest quality and reliability standards. Combining Atlas Copco's proven screw technology with long-standing in-house engineering practices, the ZS series offers unmatched reliability. Designed, manufactured and tested to ISO 9001 certified standards, ZS blowers are unparalleled in the world and mean your production never stops. Energy consumption can account for 80% of the life cycle cost of a blower. Compared to Roots blower technology, ZS series blowers reduce energy consumption by an average of 30%. Integrated Variable Speed (VSD) technology automatically and precisely adjusts compressed air flow to air demand, further reducing energy consumption. Compared with Roots blower technology, screw technology does not require replacement of belts and pulleys, which reduces maintenance costs and increases uptime. Chen Qiang, senior product expert of Atlas Copco's low-pressure air department, pointed out: "Atlas Copco's ZS series oil-free screw blower is the most advanced energy-saving product to replace Roots blower. Roots blower Due to belts, roller slips, external compression, mufflers and inlet filters, etc., the internal air flow is subject to high resistance, resulting in increased pressure drop and high energy consumption. Our ZS screw blower, built-in integrated gearbox, optimized internal air circuit, effective Reduced pressure drop and air turbulence minimizes energy costs. The performance comparison of Atlas Copco’s new ZS series screw blowers over three-blade Roots blowers has been confirmed by TüV testing according to international standard ISO 1217.” The Tianjin Sinopec Phase III project is 2x ZS132CW-J-132kW in the first phase, 5x ZS132CW-132kW in the second phase, and 5x ZS110CW-110kW in the third phase. A total of 12 ZS series screw blowers will serve for desulfurization flue gas transportation. The high-efficiency and energy-saving Atlas Copco screw blower is also making a contribution to the clean and low-carbon development of the power industry. |
