The production of thermal power forgings is an important part of the thermal power generation industry, but in the production process will produce waste water, waste gas, noise and other environmental pollution. With the continuous improvement of environmental awareness, the environmental protection requirements in the production of thermal power forgings are also constantly strengthened. Therefore, the use of environmental protection technology to reduce the impact of thermal power forging production on the environment is of great significance.
In the production of thermal power forgings, the commonly used environmental protection technologies mainly include wastewater treatment, waste gas treatment and noise control. Wastewater treatment mainly uses physical, chemical and biological methods to purify wastewater. The waste gas treatment reduces the waste gas emission by means of dust removal, desulfurization and denitrification. Noise control mainly adopts sound insulation, sound absorption, vibration reduction and other methods to reduce noise pollution.
Detailed understanding of environmental protection technology
Wastewater treatment
The wastewater in the production of thermal power forgings mainly includes cleaning wastewater, cooling wastewater and pickling wastewater. The main ways to treat these wastewater include the following:
(1) Physical method: The use of filtration, precipitation, centrifugation and other methods to remove suspended matter and impurities in wastewater.
(2) Chemical method: The use of neutralization, oxidation, reduction and other methods to treat the chemical substances in wastewater, so that it is converted into harmless substances or easy to treat substances.
(3) Biological method: The method of microbial degradation of organic matter is used to convert organic matter in wastewater into harmless substances.
Waste gas treatment
The waste gas in the production of thermal power forging mainly includes dust, sulfur dioxide, nitrogen oxide and so on. The methods of treating these waste gases mainly include the following:
(1) Dust removal: The use of bag dust collector, electrostatic precipitator and other equipment to remove the dust in the exhaust gas.
(2) Desulfurization: The use of limestone-gypsum method, ammonia method and other desulfurization technology, the sulfur dioxide in the exhaust gas into calcium sulfate or ammonium sulfate and other harmless substances.
(3) Denitration: The denitration technology such as selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) is used to convert nitrogen oxides in the exhaust gas into nitrogen and water.
Noise control
The noise in the production of thermal power forging mainly comes from the operation of mechanical equipment and the impact of materials. Noise control methods mainly include the following:
(1) Sound insulation: The use of sound insulation wall, sound insulation cover and other equipment to isolate the noise source from the external environment.
(2) Sound absorption: The use of sound absorbing materials, sound absorbing structures and other equipment to absorb noise energy and reduce noise levels.
(3) Vibration reduction: the use of vibration reduction foundation, shock absorber and other equipment to reduce the vibration and noise of mechanical equipment during operation.
Environmental protection technology application
Taking the production of turbine blades in a thermal power plant as an example, a variety of environmental protection technologies are adopted in the production process. First of all, in terms of wastewater treatment, a combination of physical and chemical wastewater treatment process is used to purify the cleaning wastewater and pickling wastewater, and realize the recycling of wastewater. Secondly, in terms of waste gas treatment, the bag dust collector and limestone-gypsum desulfurization technology are used to effectively control dust and sulfur dioxide and reduce exhaust gas emissions. Finally, in terms of noise control, equipment such as sound insulation enclosures and sound absorbing materials are used to reduce the noise level during the operation of mechanical equipment. Through the application of these environmental protection technologies, the plant has achieved good environmental protection results in the production process of turbine blades, and has improved the competitiveness and sustainable development ability of enterprises.
Environmental protection technology in thermal power forging production is an important means to achieve green manufacturing, which is of great significance to reduce environmental pollution and improve the competitiveness of enterprises. In practical applications, it is necessary to choose the appropriate environmental protection technology according to the specific situation, and comprehensively consider the factors such as technical feasibility, economy and environmental friendliness. Through continuous optimization and improvement of environmental protection technology, the efficient, clean and sustainable development of thermal power forging production can be achieved.
