Mitsui environmental protection won the bidding of jiangsu xingda steel cord co., LTD.,50T/ day sludge drying incineration project

I. project introduction
       Jiangsu xingda steel cord co., LTD. Founded thermal power plant in 1987, entered the steel cord industry in 1992, changed to joint-stock company in 1998, and went public in Hong Kong in 2006.The company is located in danan town, xinghua city, jiangsu province, about 200Km away from Shanghai and nanjing.The company has more than 7,000 employees, annual capacity of more than 600,000 tons, covers an area of 2640 mu, making the town of dai nan the world's largest steel cord production base.
       The company is based on domestic, actively participate in international competition, implement brand strategy has applied for "xingda" trademark registration in 45 countries or regions, has been basically authorized to protect.Leading products steel cord has become the qualified supplier of steel cord for APOLLO, MRF, JK of India, ARTWHEEL, KAVIR of Iran and other tire companies, and has passed the Goodyear quality system audit and entered the global procurement system of Goodyear, laying a good market foundation for the further development and expansion of the company.
       Currently, the economic development has entered a new normal. In the next five years, the company will closely focus on the established target, take steel cord production as the leading, pharmaceutical industry as the support, and special steel wire as the new economic growth point, and make steady progress in the direction of international diversification and intelligence.
       Our company won the 50T/ day sludge drying incineration project of jiangsu xingda steel cord co., LTD., and the pollutants in the flue gas of the incinerator include dust, NQX, HCL and heavy metals.
       Principle of rotary kiln incinerator
Incineration is a reliable and effective method to realize the harmless, reduction and resource utilization of waste.As a specific field of hazardous waste incineration, rotary kiln incinerator has many advantages such as wide adaptability, stable and reliable operation, convenient management and operation, simple equipment maintenance and so on to deal with complex industrial waste and medical waste. Therefore, it is most widely used in the field of international hazardous waste incineration.
Rotary burning kiln is a cylindrical cylinder with firebrick or water - cooled fireplace wall.It is through the furnace body overall rotation, so that garbage evenly mixed and along the tilt Angle to tilt end rolling state movement.In order to achieve complete incineration of garbage, there are generally two combustion rooms.Its unique structure enables several forms of heat transfer to complete the process of waste drying, volatilization analysis, waste ignition until burnout, and complete incineration in the secondary combustion chamber.Rotary kiln type incinerator has strong adaptability to incineration, especially for special refuse with high moisture content.
      


       Rotary kiln incinerator is composed of a slightly inclined furnace (one combustion chamber) and a second combustion chamber.The furnace is a hollow steel cylinder inlaid with firebricks.Heating furnace heat mainly from auxiliary fuel (oil, gas or waste liquid) and waste combustion heat.Waste with low calorific value needs auxiliary fuel for combustion, while waste with high calorific value only needs auxiliary fuel for ignition.During operation, waste enters from the high end of the furnace, and under the influence of its own gravity and furnace rotation, slowly slides down the furnace, and then goes through the drying (evaporation of water), combustion and burnout stages.
Combustion products are mainly ash and gas.The ash residue of some hazardous wastes is rich in heavy metal elements.The secondary combustion chamber is equipped with one to several burners, where the gas products are mixed with excess air in the secondary combustion chamber and burned at high temperatures to remove toxic organic compounds from the gas products.Gas-liquid form hazardous waste with high calorific value can be mixed with solid hazardous waste and put into the first combustion chamber or directly sprayed into the second combustion chamber for incineration by means of air or steam atomization.The final exhaust gas is discharged from the secondary combustion chamber into the waste heat boiler and flue gas purification device.
