II. Measures for Improving Emission Reduction Efficiency
1. Labor Automation
With the rapid development of automation technology, labor automation has become a key factor in enhancing equipment efficiency and safety. South EP's intelligent cremation equipment incorporates advanced PLC touch screen automatic control systems, significantly reducing the complexity of manual operations. This system can monitor the equipment's operating status in real-time and automatically adjust combustion efficiency based on parameters such as temperature, pressure, and air supply during the cremation process, ensuring optimal operating conditions at all times.
Specifically, the PLC system automatically collects and analyzes temperature and pressure data inside and outside the furnace, allowing for precise adjustment of air supply to achieve complete combustion of flue gas, thereby reducing pollutant emissions. Additionally, the one-click start and stop function simplifies operations, enabling cremation tasks to be completed without complicated procedures, effectively improving operational efficiency.
Furthermore, by integrating advanced IoT technology, we have developed remote monitoring and control functions. Operators can view the equipment's operating status in real-time via a remote monitoring platform and remotely operate it through smartphones or computers. This technology reduces dependence on manual labor, increases overall operational efficiency, and enhances equipment safety.
To further improve work efficiency, we have introduced the AGV robot transportation system, which plays a key role in the transportation of remains and the automated docking with cremation equipment. This system reduces manual intervention, enhancing service efficiency and accuracy. This technology not only saves manpower but also improves the overall operational efficiency and safety of the equipment.
2. Energy Efficiency and Fuel Consumption Reduction
Fuel consumption and energy efficiency are important components of the operating costs of cremation equipment. South EP has adopted several innovative technologies to significantly reduce fuel consumption. We have optimized the design of the combustion chamber and implemented high-efficiency secondary combustion technology, ensuring that flue gas between the main combustion chamber and the reburn chamber undergoes complete combustion, greatly reducing oil and electricity consumption.
In traditional cremation equipment, incomplete combustion often leads to energy waste and the generation of harmful gases. To address this issue, we have introduced a closed-loop combustion control system. This system continuously monitors and adjusts oxygen levels and furnace pressure in the combustion chamber to ensure efficient combustion. As a result, cremation machines have reduced energy consumption by 25%.
In addition, the equipment is equipped with high-efficiency heat exchangers and waste heat recovery systems. The heat exchanger preheats incoming air using heat generated during combustion, reducing additional fuel consumption. The waste heat recovery system converts part of the waste heat into useful thermal energy, further improving energy utilization efficiency.
3. Emission and Solid Waste Gas Treatment
Environmental performance is a key focus in the design of modern cremation equipment. South EP has adopted multiple leading technologies in emission and solid waste gas treatment to ensure that our equipment meets or exceeds national standards. During the cremation process, harmful substances in flue gas primarily include sulfur dioxide, nitrogen oxides, and dioxins. To effectively reduce these emissions, we have introduced an emergency cooling system, desulfurization and denitrification technology, combined with activated carbon adsorption technology, to efficiently filter and absorb harmful substances in flue gas during cremation.
Specifically, the emergency cooling system can rapidly cool high-temperature flue gas from 800°C to below 200°C within 2 seconds, preventing the secondary formation of harmful dioxin gases. The desulfurization and denitrification technology converts sulfur dioxide and nitrogen oxides in the flue gas into harmless substances through chemical reactions, ensuring that emissions comply with the national standard for crematoria atmospheric pollutant emissions (GB13801-2015). The activated carbon adsorption system effectively captures fine particulate matter and volatile organic compounds, further improving flue gas purification efficiency.
South EP's intelligent cremation equipment is also equipped with a centralized dust collection device, which collects dust generated during the cremation process to prevent pollutant leakage, protecting both the operational environment and personnel health. Actual test results show a 99% reduction in dust emissions, a 90% reduction in sulfur dioxide, and a 60% reduction in nitrogen oxides.
4. Equipment Safety and Stability
The safety and stability of cremation equipment are critical performance indicators. To ensure the long-term stable operation of the equipment, we have selected high-strength, high-temperature, and corrosion-resistant materials in the design. For instance, the furnace of the cremation machine is made of high-strength silicon carbide bricks, which maintain stable physical and chemical properties at high temperatures, extending the equipment's lifespan. The main machine equipment has a service life of no less than 10 years and can handle more than 10,000 remains, greatly enhancing the equipment's cost-effectiveness.
At the same time, the external components of the equipment are covered with anti-corrosion and high-efficiency insulation materials, effectively reducing heat loss and ensuring stable thermal efficiency during long-term use. For the operational status of the cremation machine, we have also introduced an intelligent fault detection and automatic alarm system. The equipment continuously monitors its operating conditions, automatically alerting and recording fault information in case of a malfunction, allowing maintenance personnel to respond promptly, reducing downtime, and ensuring high operational efficiency and stability.
5. Optimized Combustion Technology
To further enhance combustion efficiency and reduce the generation of harmful gases, we have optimized the design of the combustion chamber. The main combustion chamber and reburn chamber are connected by an extended flue design, increasing the retention time of flue gas, allowing it to fully combust in the secondary combustion chamber, thereby reducing the emission of unburned particulates and harmful gases.
Additionally, we have incorporated a three-dimensional air supply system in the equipment. By strategically placing multiple air supply points within the furnace, the system ensures thorough mixing of flue gas with oxygen, improving combustion efficiency. This technology not only reduces fuel consumption but also effectively decreases the emission of particulates, carbon monoxide, and nitrogen oxides.
