The present invention belongs to an energy supply system, and particularly relates to a kind of waste plastics and organic matter household garbage continuous infusion and removal type fixed bed gasification apparatus.

The primary way in which humans gain thermal energy and kinetic energy is the large amount of energy that is released through the combustion of fuel and oxygen. However, in today's shortage of resources, energy issues have already emerged as one of the most important strategic issues around the world. There are three types of energy fuels: gas fuels, liquid fuels and solid fuels. Fossil energy is natural gas, oil and coal. As we know, fossil energy contains coal, and oil and natural gas are non-renewable energy. However, biomass energy is a kind of regenerable energy typical for plant-optical joints of fixed solar energy on earth.

On the other hand, solid wastes are also abbreviated as solid wastes, which are solid and sludge materials that are left in production and life activities. Commonly visible combustible solid waste is flammable solid waste such as urban waste, waste plastics, agriculture and forestry biomass waste, and medical waste.

These wastes can be used to replace coal, oil, and natural gas to reduce dependence on mineral energy, protect the country's energy resources and reduce environmental pollution from energy consumption. Therefore, we are actively promoting the development of renewable energy internationally. Among them, waste plastics and organic matter Gasification of household garbage is an important direction of energy research around the world at present. However, the problem of production cost of gasification technology and quality of produced gas has not been solved in domestic and foreign countries. Therefore, the supply of domestic garbage gasification such as waste plastic and organic matter is not yet popularized.

On the other hand, the main energy source components of biomass are organic volatile matter and fixed carbon, and biomass is a substance such as combustible gas, tar and residues produced during the heating process. The ultimate goal of producing biomass as a gas is to convert as much biomass into gas as possible with the vaporization of biomass and to minimize or eliminate tar and residues.

At present, the shortcomings of the gas generators that are released on the market are: long vaporization time, low gas production, large amount of tar in the gas, large amount of self energy consumption and especially low production of gas and low thermal calorie Temperature is 750 ℃ ~ 850 ℃), we are not able to apply it to large-scale industrial or city gas supply.
