There are many ways to deal with garbage in my country, such as recycling, sanitary landfill, garbage incineration, composting, etc. Different types of garbage have different disposal methods. Now, waste incineration power generation has become the mainstream of waste treatment. Many cities centrally incinerate domestic waste to achieve reduction and harmlessness of waste. At the same time, the heat generated by waste combustion can generate electricity and realize waste recycling.
The popularity of waste incineration power generation in big cities is not only because of its harmless and reduced waste treatment, but also because its environmental protection concept of sustainable development and resource reuse has been widely recognized by the society.
Waste-to-energy plants are fundamentally different from other power plants. The composition of each fuel in a waste incineration power plant is different, and the design requirements of ventilation equipment are also different. The fuel of waste incineration power plants is complex domestic waste, and the fuel of ordinary power plants is coal, natural gas, etc. Therefore, it must also be differentiated from other power plants in the ventilation design process.
The characteristics of waste incineration power plants are: First, the pollution to the surrounding environment during the process of domestic waste treatment, such as odor pollution, microbial pollution, etc. These pollutions must be dealt with effectively, otherwise it will seriously affect the health of local people. Secondly, domestic waste may produce secondary pollution during the treatment process. Therefore, the waste incineration power plant must carry out ventilation design in the waste treatment process. In addition to meeting the requirements of the construction industry and the power industry, the ventilation design must be able to meet some requirements of the waste power plant to ensure that no secondary pollution is generated during the power generation process. Avoid having a large impact on the surrounding environment.
The garbage pond adopts a ventilation system of mechanical exhaust and natural supplementary air. The mechanical exhaust uses an industrial fan, and the air volume of the industrial fan is 14130m³/min. Since the leachate contains CODcr, B0D5, NHs-N and other pollutant indicators exceeding the standard, there are various corrosive gases and pollutants such as halogenated aromatic hydrocarbons, viruses and heavy metals, so anti-corrosion and explosion-proof industrial fans should be selected.
Industrial fan ventilation and deodorization
The odor of the waste incineration power plant is mainly concentrated in the areas such as the garbage pool, the unloading hall, and the vicinity of the iron remover. Employees should pay special attention to deodorizing these premises. Industrial fans are installed in the discharge hall and ash room for deodorization, and physical technology is used for deodorization.
The ventilation technology of waste incineration power plants is a new technology. Its application can solve the problem of secondary pollution caused by waste incineration and play a better role in environmental protection.
