 pyrolysis and gasification process of municipal solid waste
Description of the pyrolysis and gasification process of municipal solid waste:
Pyrolysis gasification technology is a brand-new waste treatment method: its greatest advantage is to overcome the disadvantages of using incineration methods to produce dioxins. This technology creates a new process flow by combining several traditional and mature technologies. It combines innovative pyrolysis technology and traditional high temperature oxygenation technology to simulate the chemical process in the formation and vaporize the waste. Pyrolysis gasification technology can process all types of waste, such as waste electrical appliances, batteries, printer cartridges, disposable infusion sets, injectables, etc., without any prior sortation. After crushing the garbage, the organic components of the waste are vaporized at a high temperature of about 400°C, and the inorganic components are melted. Then, the temperature is quickly reduced to 75°C in a short period of time to avoid the formation of dioxins and the waste is completely converted into Syngas and recyclable trace solid residues, the ineffective components of the waste are melted and hardened to form a useful new material wall material.
The advantages of pyrolysis and gasification of municipal solid waste:
1. The incoming rubbish is broken by a fan and sent directly to the reactor for processing.
2. The power that can be realized in production can be self-sufficient, and no external industrial water or electricity is needed.
3. No pollution emissions such as waste gas, liquid waste, and waste, ie no new-born harmful substances in production.
4. The organic wastes are converted into valuable primary resource materials such as oil, gas, and charcoal after reductive cracking (The actual production results show that the average output of crude oil per ton of domestic waste is 10-30 kg and 100-150 kg of biochar. Combustible gas 100-120 cubic meters, in which the calorific value of the oil is more than about 10,000 calories per kilogram, and the calorific value of charcoal is about 2000-3000 calories per kilogram).
5. Through process optimization and combination, the waste gas and waste water produced in the production process are self-digested and used by self-contained recirculation, which not only solves the problem of material consumption and energy production, but also eliminates the harmful discharge of the production process to the environment. .
6, in the device configuration and heat transfer combination, the use of thermal field effects, the establishment of a temperature gradient stepped heating field, effectively solve the problem of the heat transfer between the solid material flow.
7. Aiming at the mechanical problems of solid waste flowing in the kettle, a technology that allows the creep of solid materials has been invented in a pioneering manner. The mechanical force conversion method is used to generate internal forces for the garbage to solve the problem of the flow of garbage in the kettle. In order to realize the continuity of the processing process, it has laid an effective technical support for the equipment.
