Vølund Technical advantages of Lund grate furnace Maturity Over 80 years of experience, we have achieved over 500 sets of incinerator grate applications. reliability Hydraulic driven mechanical reciprocating forward push grate furnace, row driven grate, with low wear and tear: The hydraulic cylinder driven by the grate is located outside the grate, with low ambient temperature and high reliability. Progressiveness The design of a forward pushing grate combined with steps effectively enhances the mixing of garbage in the furnace, ensuring combustion efficiency; Low mechanical load and strong overload capacity of the grate The primary air is supplied separately by zones, while the secondary air is supplied in layers. The air volume of each branch pipeline can be accurately measured and independently controlled, achieving full combustion; According to "3T+E" Principle design, CFD simulation design, effectively reducing NOx, CO, and dioxin emissions; The grate is designed and supplied in a modular way. The ejector and each section of grate are delivered as a whole. The on-site installation workload is small, and the installation cycle is short. The ACC (Automatic Combustion Control) system can be put into 100% automatic operation. By adjusting the feeding amount, grate operating speed, air volume of each branch pipe and other parameters, the stable automatic control of evaporation and furnace temperature can be realized, and the system operation stability is high. adaptability Adopting high-temperature primary air combustion can adapt to China's low calorific value, high moisture content, and complex components of sorted household waste. Maintenance convenience The grate plate does not require bolt connections, making it easy to install, repair, and replace. The operation of replacing the grate plate can be completed on top of the grate plate.

PNCR Waste Incineration Flue Gas Denitration Technology The PNCR waste incineration flue gas denitrification technology is a dry catalytic denitrification method. The PNCR denitrification agent does not contain toxic, harmful, and expensive metal elements such as vanadium, tungsten, and molybdenum, nor does it contain organic matter, avoiding the risk of increased dioxin emissions. There is no secondary pollution during use. This technology can also collaborate with SNCR to achieve low-cost NOx removal, thereby replacing traditional SCR denitrification technology. advantage Containing catalyst The PNCR denitrification agent developed by Zhongke Environmental Protection mainly consists of amino compounds and catalysts. No production of dioxins The Zhongke Environmental Protection PNCR denitration agent does not contain catalysts and precursors that can lead to the generation of dioxins, and does not pose a risk of increased dioxin emissions. The material is non-toxic, harmless, and free from secondary pollution Zhongke Environmental Protection PNCR denitration agent does not contain toxic and harmful metal elements such as vanadium, tungsten, and silver, and there is no secondary pollution during use Equivalent to SNCR+SCR The denitrification principle of Zhongke Environmental Protection PNCR denitration agent: The PNCR denitrification process involves both selective catalytic reduction (SCR) and selective non catalytic reduction (SNCR) reactions. Amino compounds reduce NO. to nitrogen and water, achieving NOx emission standards, which is equivalent to the combination of SNCR and SCR reaction principles Large reaction zone and high efficiency NOx undergoes a reduction reaction in the second flue, third flue, and horizontal flue Industrialization of Biological Natural Gas The company has accumulated years of technical experience and production practice in domestic waste incineration power generation projects, and has also made progress in biological natural gas purification and utilization technology. The holding company, Zhongke Energy Environment, has a technological leading advantage in this field The pollution of the alcohol industry is most severe in terms of water pollution. Alcohol wastewater is an organic wastewater with high concentration, high temperature, and high suspended solids, which can easily cause eutrophication of the water body and is difficult to treat. This project uses biogas generated by anaerobic fermentation of alcohol wastewater as raw material, mainly using chelation desulfurization, compression, and PSA decarbonization technologies to produce green energy bio natural gas

Domestic waste treatment CSET mainly engages in the investment, construction, and operation of household waste incineration power generation projects through franchise operations such as BOT and BOO. Conduct harmless incineration treatment of household waste and carry out resource utilization around thermal energy, generate electricity through steam turbine generators, and provide heating services to surrounding industrial enterprises using the "cogeneration" model On this basis, the company adheres to the concept of circular economy, continuously practices and successfully establishes a circular economy industrial park model, adds new business for the treatment of kitchen waste, sludge, and medical waste, greatly improving its level of reduction and resource utilization Social and Economic Benefits After incineration, the volume of landfill decreases by 95% Each ton of garbage can generate about 380 kilowatt hours of electricity, which can supply a family of three for about 3 months After incineration, the harm to the environment and human health is greatly reduced CHP provides green heat energy In the context of dual energy consumption control, the project adopts the "cogeneration" model to provide heating services to industrial enterprises within the industrial park where the project is located, achieving diversified, efficient, and high value-added utilization of thermal energy, and becoming the local infrastructure that provides heat source protection for economic development. Through the "cogeneration" model, the utilization effect of domestic waste resources is more significant, and the social benefits and economic value of the project are also improved Circular Economy Industrial Park Green cycle helps with the construction of "waste free cities" The circular economy industrial park collaborates on the treatment and disposal of various types of urban waste such as household waste, kitchen waste, urban sludge, and medical waste. While achieving harmless waste treatment, the generated green energy such as electricity, heat, and biogas can be utilized in a tiered manner, improving energy efficiency, and achieving low-cost and efficient disposal of secondary pollutants. The company's Mianyang project belongs to the first batch of 50 resource recycling bases in China Park Process Cycle Flowchart Power cycle The electricity generated by the garbage incineration power generation project is supplied to the park project for self use, and the remaining electricity is input into the national power grid Thermal energy cycle The steam generated by the waste incineration power generation project serves as a heat source for sludge drying in sludge treatment projects, pre-treatment of kitchen waste treatment projects, and medical waste steaming and sterilization treatment Utilization of biogas The anaerobic generated biogas in the park enters the waste incineration power generation project for incineration or purification and compression into CNG Sewage treatment The leachate and sewage generated in the park enter the leachate treatment station for centralized treatment Water recycling The leachate can meet the standard after treatment. Reuse of clean water for slag extractors, fly ash stabilization, circulating cooling, flushing of factory roads and production workshops, and greening irrigation Waste disposal The sludge, biogas residue, etc. generated by each project are treated and sent to the incineration power generation project for mixed incineration with household waste. The waste residue generated from incineration is comprehensively utilized
