Project Background

Coal-fired pollutants discharge a lot and cause heavy pollution. If all of them are burned with natural gas, the natural gas resources will be insufficient. In this case, it is the only way to solve the pollution control and energy problems in China to achieve "ultra-low emission" of coal-fired pollutants and meet the national emission standards of gas turbines. Promoting the "ultra-low emission" of coal-fired generating units in China is a concrete action to promote the energy revolution and implement the air pollution prevention and control action plan. It is the only way to promote the sustainable development of electric power industry.

General contracting project of wet flue gas desulfurization and deep purification of Hangzhou Jiangdong Fulida Thermal Power Co., Ltd.

Technical Characteristics

1) Relying on Zhejiang University, it has a large-scale ultra-low emission test platform to master all laws and data of various pollutants;

2) Design process can avoid scaling, blockage, has low resistance and less operation and maintenance; The engineering application is mature, and the long-term operation reliability of the system is high;

3) Desulfurization, dust removal and chimney can be arranged in an integrated way, with modular design and flexible arrangement mode, without excessive installation space and short construction period;

4) strong adaptability of coal, high utilization rate of limestone, and low calcium-sulfur ratio; The desulfurization efficiency can reach over 99.6%;

5) A booster with independent intellectual property rights of Pyneo is arranged in the absorption tower;

Solution

The construction scale of Hangzhou Jiangdong Fulida Thermal Power Co., Ltd. owns three 75t/h high-temperature and high-pressure circulating fluidized bed boilers and four 130t/h high-temperature and high-pressure circulating fluidized bed boilers.

In this project, limestone-gypsum wet flue gas desulfurization technology plus wet electrostatic precipitator are used for desulfurization and dust removal, and the treated flue gas is directly discharged through the top chimney. A booster with independent intellectual property rights of Pyneo is arranged in the absorption tower to improve the desulfurization efficiency. The wet electrostatic precipitator is arranged above the absorption tower, with low system resistance and low running energy consumption. This project is designed for the integration of desulfurization, dust removal and chimney, with a small floor area and beautiful appearance, thus achieving the goal of ultra-low emission as a whole.

Get The Effect

According to the Technical Requirements for On-line Monitoring of Ultra-low Emission and Low Concentration of Thermal Power and Industrial Boilers in Hangzhou, after monitoring, the emission concentration of sulfur dioxide is 6mg/Nm3 minim, with an average of 14mg/Nm3 and a maximum of 20mg/Nm3. The lowest smoke emission concentration is close to 0mg/Nm3, the average is 1.5mg/Nm3, and a maximum of 3mg/Nm3.
