Nanjing Zhuoyue Environmental Protection Technology Co., Ltd. was founded in 2014, the total area of the project is about 133,000 square meters, is a focus on environmental protection technology research and development and environmental services of high-tech environmental protection enterprises. Based on the industrial hazardous waste treatment business, the company develops value-added businesses such as environmental engineering and services, gives full play to the advantages of the industrial chain, and casts an all-round solid waste treatment service platform.

On the basis of the "waste free city" construction pilot program implemented by the state, Nanjing Zhuoyue Environmental Protection Technology Co., Ltd. has invested in the construction of a resource utilization production line with an annual treatment of 120,000 tons of industrial solid waste, including 80,000 tons of hazardous waste and 40,000 tons of general solid waste.

The project adopts advanced oxygen-rich side-blowing and melting technology, takes resource utilization of copper, nickel and precious metal waste as the main line, collaborates with other solid waste, realizes waste treatment by waste, and considers waste heat recovery and utilization, and completely realizes harmless, resource utilization and reduction of solid waste. The construction of the project not only realizes the utilization of resources, but also solves the environmental risks and hidden dangers of hazardous waste landfill and the land resources problems faced by development, and has good economic, social and environmental benefits.

Shanghai Changying Environmental Protection Service Co., Ltd. is located in Fengxian District, Shanghai Chemical Industrial Zone, covers an area of 19,300 square meters, and is one of several hazardous waste incineration and disposal enterprises established in the early days of Shanghai. The company's annual processing capacity of hazardous waste is 25,000 tons/year, and the general solid waste volume is 16,000 tons/year.

With advanced equipment, creative management system and experienced operation team, Changying Environmental Protection has become a benchmark enterprise in the hazardous waste industry in China.

● Rotary kiln production line

"Changying Environmental Protection" has put into operation a new rotary kiln production line with an annual disposal capacity of 25,000 tons, which can treat 19 types of hazardous waste such as HWO2, HWO3 and HWO4. The rotary kiln equipment of this project adopts a variety of domestic advanced technologies, which is a domestic digital, high degree of automation, a wide range of hazardous waste disposal and a very safe incinerator.

SMP system

SMP system is a set of foreign advanced technology material handling and feeding system, the system combined SMASH(crushing), MIX(mixing), PUMP(pumping) function as one, and the use of nitrogen protection, can safely dispose of a large number of other enterprises can not dispose of a large number of hazardous waste, pump flow peak 3m3h, It greatly solves the difficult situation of laboratory waste and semi-solid hazardous waste in Shanghai area.

● Automatic feeding system

The new production line is equipped with a variety of hazardous waste feeding systems, all incoming materials will be tested by the laboratory in advance, and according to the test data, the system will automatically match the high and low calorific value of hazardous waste and the high sulfur, high chlorine and high heavy metal content, so as to ensure the economy of the entire incineration line and the standard of incineration exhaust emissions.

● Automatic incineration control system

In the central control room through the computer monitoring system to achieve the hazardous waste incineration system, flue gas purification system centralized industrial television monitoring and control, through SOz, HCI emission concentration control lime or baking soda and liquid alkali concentration and feed amount; According to the heavy metal and dioxins detection data, the feed amount of activated carbon is adjusted regularly.

● Waste heat recovery power generation system

The new incineration line can be used for steam reference flow of 7t/h and pressure of 1.2MPa, and the steam can be recovered by a turbine power generation system. The net power generation is 780KW per hour on average, the annual electricity saving is 5.46 million KWH, and the annual electricity saving benefit is 4.368 million yuan.
