The first chemical odor management method in China

Drying equipment

The domestic chemical odor control method adopted by the Zibo Thermoelectric Group Co., Ltd. —the thermal power plant boiler incineration chemical waste gas pollution control and energy-saving technology project was recently named Shandong Provincial Department of Human Resources and Social Security as the demonstration base for the introduction of foreign intelligence achievements in Shandong Province. The project will uniformly incinerate the exhaust gas of five chemical companies in the eastern chemical zone of Zibo, which will not only reduce emissions, but also save a lot of energy consumption for enterprises.

The project will consist of 5 units of Lanxing Dongda Chemical Co., Ltd.'s propylene oxide plant in Zibo East Chemical Industry Park, a branch of Shandong Xinhua Pharmaceutical Co., Ltd., a high-tech chemical plant, Zibo Jinma Chemical Co., Ltd., and Zibo Huanlv Company. The company's waste gas is collected and put together for incineration. It can reduce the emission of chemical waste gas and odor by about 800 million cubic meters per year. It saves nearly 24 million cubic meters of natural gas for 5 chemical companies, equivalent to 28,100 tons of standard coal, and has achieved tremendous social benefits. And environmental benefits.

It is understood that the project was officially completed and put into operation in February 2011. Prior to this, chemical odors generated by several large chemical companies in the eastern chemical district of Zibo Central District often affected the downtown area. To this end, Zibo City proposed hiring foreign environmental protection experts to participate in environmental management in Zibo City.

In 2008, Zibo City hired a Japanese environmental protection expert to address issues such as the concentration of eastern chemical companies, concentration of exhaust emissions, and the generation of toxic gases such as dioxin at low temperatures. It was proposed that chemical waste gas be collected and passed through a high-temperature boiler above 1,200°C from Zibo Thermoelectric Group. Focus on burning advice.

After many rounds of argumentation by experts in the organization, it finally determined the implementation of this domestic initiative for governance. Since August 2009, the Zibo Thermal Power Group has invested more than 30 million yuan, has overcome a number of technical difficulties, completed the upgrading and reconstruction of the boiler exhaust gas and put into operation.

At present, according to the online monitoring device installed by the Environmental Protection Bureau of Zibo City, the analysis shows that after the project was put into operation for more than one year, the chemical waste gas was burned at a high temperature of 1200°C or more, and only the carbon dioxide and water vapor remained in the air that was finally discharged into the atmosphere were harmless. Gas, chemical waste gas from a "burn" and light.
