Method for preparing combustible gas from municipal domestic waste and plant waste

Abstract

The invention relates to a method for preparing combustible gas from municipal domestic waste and plant waste, which comprises steps as follows: after mixing and pulverizing selected municipal domestic waste and plant waste, the mixture is sent into a synthesizing tower to be subjected to pyrolysis, and generated gas is filtered by a water filter tank, a CO2 filter, a sponge filter tank, a palm leaf filter tank and an active carbon filter tank, and sucked into a gas storage tank to be stored. The invention also provides a synthesizing tower for preparing combustible gas. A jacket above a high-temperature rotating heating unit penetrates through the upper wall of the synthesizing tower body and is communicated with a second material warehouse, a mixer is arranged in the second material warehouse, and a deslagging port on the bottom of the synthesizing tower body is provided with a deslagging propeller. The method for preparing combustible gas from municipal domestic waste and plant waste and the synthesizing tower provided by the invention can be used for preparing combustible gas by treating municipal domestic waste and plant waste, and synthesizing methanol by directly utilizing or utilizing the existing equipment and technique, thereby saving the energy sources and protecting the environment.

Description

technical field [0001] The invention relates to a waste utilization transformation method, in particular to a method for preparing combustible gas from municipal domestic waste and plant waste. Background technique [0002] Municipal solid waste and plant waste have become the main sources of waste. The existing waste disposal methods mainly include landfill, burning and reclamation. The disadvantages are as follows: [0003] 1) The cost of the burial method increases with the increasing difficulty of land acquisition; it is easy to generate secondary public hazards such as odor, waste water, insects, flies, and germs; the land after burial cannot be used again, resulting in permanent land waste; [0004] 2) The incineration method increases the fuel cost; it is easy to produce toxic gas, which endangers the health of the whole people; and it will destroy the atmosphere and the ozone layer; [0005] 3) Sea reclamation will cause permanent pollution of marine ecology.

Problems solved by technology

[0003] 1) The cost of the burial method increases with the increasing difficulty of land acquisition; it is easy to generate secondary public hazards such as odor, waste water, insects, flies, and germs; the land after burial cannot be used again, resulting in permanent land waste;

[0004] 2) The incineration method increases the fuel cost; it is easy to produce toxic gas, which endangers the health of the whole people; and it will destroy the atmosphere and the ozone layer;

[0005] 3) Sea reclamation will cause permanent pollution of marine ecology

[0006] At present, there is no method of using municipal solid waste and plant waste to prepare combustible gas, and the energy sources such as petroleum and coal that people are using are non-renewable. Extracting energy from municipal solid waste and plant waste provides energy for human beings. Crisis offers a new solution
