It breaks through the inherent technical bottlenecks of traditional waste disposal methods (landfill and incineration), and realizes the coordinated advancement of waste harmless treatment, volume reduction, and resource recycling. Compared with traditional treatment facilities and similar environmental protection equipment, it has multiple core advantages including outstanding environmental performance, energy-saving and high efficiency, wide application adaptability, convenient operation and maintenance, and safe and stable operation. It is suitable for diversified scenarios including urban and rural areas, scenic spots, and industrial parks, providing an efficient and feasible solution for comprehensive waste management, and supporting the implementation of ecological environmental protection and the "Dual Carbon" goals.

Industry-Leading Environmental Performance

This equipment fully aligns with global green development requirements, and fundamentally solves the secondary pollution risks that are difficult to overcome by traditional waste treatment methods.

Pain points of traditional treatment processes: Traditional landfill is prone to produce a large amount of leachate, which infiltrates into soil and groundwater, causing long-term soil and water pollution. Meanwhile, waste fermentation releases malodorous gases such as methane and hydrogen sulfide, polluting the atmospheric environment. Traditional incineration technology tends to produce harmful substances such as dioxins, NOx, and VOCs. Among them, dioxins, as strong carcinogens, are difficult to be completely degraded, posing a serious threat to the ecological environment and human health.

Full closed-loop pollution prevention design: The equipment adopts a fully enclosed negative pressure design, and the whole process of waste from feeding, storage to pyrolysis and final treatment is completed without landing and leakage, which effectively prevents the unorganized emission of malodorous gases and thoroughly solves the odor disturbance problem in the waste treatment process.

Dioxin elimination from the source: In the core pyrolysis link, the reaction temperature is strictly controlled at 650-930℃, which directly destroys the formation conditions of dioxins and other harmful substances, avoiding the massive generation of dioxins in the low temperature section (200-400℃) of traditional incineration. The combustible gas produced by pyrolysis undergoes secondary combustion at a high temperature of 870-1000℃ to further decompose residual pollutants, ensuring clean gas emission.

Multi-stage flue gas purification system: The equipment is equipped with a combined flue gas purification system including activated carbon adsorption + bag dust removal, high-efficiency catalytic conversion, and high-voltage electrostatic capture. It carries out multi-stage filtration and degradation of pollutants such as NOx, VOCs, CO and particulate matter in the flue gas. The emission indicators are far lower than the national GB 18598-2019 Standard for Pollution Control on Municipal Solid Waste Incineration and relevant EU standards. Some high-end models can realize cold emission below 35℃, avoiding thermal pollution and haze formation.

Zero hazardous waste liquid discharge: The leachate produced by pyrolysis can be treated by waste heat evaporation, and the ash residue can be recycled after harmless treatment, without hidden danger of secondary pollution, truly realizing "zero pollution and zero residue" of waste treatment.

Significant Energy Saving Effect

Compared with traditional incineration equipment that requires a large amount of auxiliary energy (such as natural gas, diesel) to maintain combustion, this equipment has outstanding energy-saving advantages.

Self-sustaining operation by waste inherent calorific value: It can maintain stable operation relying on the calorific value of the waste itself, without a large amount of external auxiliary energy input. Even for raw waste with a low calorific value as low as 900kcal/kg and high moisture content, it can achieve efficient and stable operation, greatly reducing energy consumption costs.

Comprehensive waste heat recovery system: The high-temperature flue gas released after the combustion of combustible gas from pyrolysis recovers heat through the heat exchanger, which can be used for waste pyrolysis preheating and leachate evaporation, minimizing energy waste. The recovered waste heat can also be converted into 95℃ sanitary hot water for surrounding residents, enterprises or the waste treatment station itself, realizing energy recycling and further improving the energy-saving benefit.

Ultra-low comprehensive operating cost: To treat 1 ton of waste, the equipment only consumes a small amount of water and electricity. Compared with the land occupation cost and leachate treatment cost of traditional landfill, as well as the auxiliary energy cost of traditional incineration, its comprehensive operating cost can be reduced by 30%-50%. Long-term use can significantly save waste treatment investment, which is suitable for promotion in counties, towns and small cities with limited capital budget.

Ultra-high volume reduction rate: The equipment has a waste volume reduction rate of over 90%, which can greatly reduce the land occupation for waste landfill, ease the pressure of tight land resources, and indirectly reduce the economic and ecological costs caused by land occupation.

Wide Adaptability

The Garbage Pyrolysis Comprehensive Treatment Equipment has extremely strong adaptability, and can be customized according to actual waste treatment demands.

Wide compatibility of waste types: No need for pre-crushing and sorting of waste, it can directly treat various wastes including domestic waste, garden waste, kitchen waste (after simple dehydration), and small industrial waste, solving the problem of traditional equipment with high requirements on waste components and single adaptability, especially suitable for urban and rural areas with complex waste components and difficult sorting.

Flexible configurable treatment scale: The equipment can be flexibly configured according to actual needs, from small scale (5-20 tons per day), medium scale (20-50 tons per day) to large scale (over 50 tons per day), which can accurately match the waste treatment needs of different scenarios such as small cities, counties, towns, scenic spots and industrial parks. It can not only realize on-site treatment of scenic spot waste and reduce transportation costs, but also meet the needs of centralized comprehensive treatment of urban and rural waste.

Strong adaptability to waste properties: It has strong adaptability to the moisture content and calorific value of waste. Whether it is raw waste with high moisture content or mixed waste with low calorific value, it can achieve ideal treatment effect without additional combustion improver, further reducing operating costs and operation complexity.

Compact footprint: Compared with traditional waste landfills and incineration plants, its floor area is only 1/5-1/3 of traditional facilities. It can be renovated and upgraded on the basis of the original waste treatment station without large-scale land acquisition, which is suitable for areas with tight land resources such as urban peripheries and scenic spots. It can also transform the waste treatment station into a landscape facility to improve residents' acceptance.

Intelligent & Convenient Operation and Maintenance

Full automatic intelligent control system: The equipment adopts a full automatic control system, equipped with an intelligent PLC control system and an online continuous monitoring system, which can realize remote operation, real-time monitoring and intelligent regulation of equipment operation. Operators can take up posts after simple training, greatly reducing labor input.

Full traceable online monitoring: The online continuous monitoring system can real-time monitor flue gas emission and equipment operating parameters (temperature, pressure, flow, etc.), and the data is synchronously uploaded to the environmental protection department and operation center, realizing full traceability and supervision, and avoiding environmental protection risks and potential safety hazards caused by illegal operation.

Modular design for easy maintenance: The equipment adopts a modular design, each system operates independently and works collaboratively. The subsequent maintenance is convenient, and the replacement of vulnerable parts is simple, no professional maintenance team is required, which can reduce the difficulty and cost of operation and maintenance.

Long service life & low noise operation: The equipment has no complex mechanical wear during operation, with a service life of up to 15-20 years. Compared with traditional equipment (service life of 8-10 years), it can reduce the investment caused by equipment replacement and improve the comprehensive cost performance. In addition, the equipment operates with low noise and no obvious odor, realizing "silent and odor-free" operation, reducing the impact on the lives of surrounding residents, improving the surrounding environmental quality of the waste treatment station, and reducing residents' complaint rate.

Safe & Reliable Operation

Multiple safety protection mechanisms: The Garbage Pyrolysis Comprehensive Treatment Equipment fully considers safety performance in the design process, and adopts multiple safety protection devices, including over-temperature alarm, over-pressure protection, flameout protection, etc., which can effectively prevent potential safety hazards during equipment operation and ensure long-term stable operation of the equipment.

High-value resource recycling of solid residue: The solid ash produced by pyrolysis is rich in potassium, phosphorus, calcium and other elements. After harmless treatment, it can be used for soil improvement to improve soil fertility and support the green development of agriculture; it can also be used as raw material for building materials to make bricks, concrete aggregates, etc., realizing the resource recycling of solid waste.

Energy self-sufficiency & carbon emission reduction: The combustible gas produced by pyrolysis can be used for its own pyrolysis reaction after treatment, realizing energy self-sufficiency, reducing the consumption of fossil energy, lowering carbon emissions, and helping to achieve the "dual carbon" goals.

Closed-loop circular economy system: Compared with traditional waste treatment methods, this equipment can realize the "waste to treasure" of garbage, which not only solves the waste treatment problem, but also realizes resource recycling, builds a closed-loop system of "waste treatment - resource recovery - energy utilization", and promotes the development of the waste treatment industry towards green, low-carbon and resource recycling.
