A refining and conversion process technology for biomass cracking and conversion treatment, which is characterized in that: the process technology includes: 1), no external source and low energy consumption treatment technology of domestic waste; 2), garbage treatment system Secondary pollution process control technology; 3) Facilitated control technology for waste treatment; 4) Low social cost control technology for waste treatment; 5) High-temperature organic carbon discharging operating procedures; through engineering process coverage tests, we have achieved Engineering technical means and process methods that can solve the flow heating control and energy efficiency balance of solid waste; its specific working steps are: 1). Non-external source and low energy consumption treatment technology of domestic waste. The energy demand and consumption during the entire treatment process are considered. Mainly utilizing the energy content of the garbage itself, it is a multi-form energy efficiency conversion and utilization technology. Its regeneration system can not only meet the energy consumption of the garbage itself, but also produce a considerable amount of abundant energy output; 2) Secondary use of the garbage treatment system Pollution process control technology steps 1. Retort coking uses retort coking technology, which requires the system to be completely oxygen-isolated and effectively eliminates the basic conditions for the formation of "dioxins" in the system; Step 2. Liquid-phase absorption of low-sulfur smoke present in the system The gas will not be discharged directly into the air, but will be absorbed by the system in liquid phase and then processed in a centralized manner; Step 3. Comprehensive utilization or centralized conversion of waste residue or ash powder generated in garbage treatment, subject to the permission of the project portfolio investment, according to the comprehensive utilization Or centralized conversion plan for selective treatment; Step 4. The reused or limited wastewater system will be collected separately according to the production system requirements of each device and centrally processed until it meets the standards allowed by the working conditions, and then reused or discharged in a designated limited manner; 3) Convenient control technology steps for garbage disposal 1. Distributed production and processing are mainly based on centralized automatic program control, supplemented by human power; Step 2. Systematically configure units and operating methods in each process link of garbage disposal Basically, the currently quite mature and reliable process equipment and technology are used for systematic configuration; Step 3. Raw material quality The raw material quality requirements for domestic waste are relatively broad and can be adapted to various types and daily calorific value contents. Domestic waste; 4) Low social cost control technology steps for waste treatment 1. System design. During the design process of this waste treatment system, the investment setting of the project construction is relatively strictly controlled, basically achieving the lowest cost. Engineering investment to obtain the best economic feasibility and commercial benefits of the project; Step 2. Low consumption control of operating costs: In the design and configuration of the entire device, the daily operating costs are fully calculated and optimized, basically Operate in a state of relatively low consumption costs.
