Garbage gasification and biomass combustion integrated system

Abstract

The invention relates to the field of garbage treatment, in particular to a garbage gasification and biomass combustion integrated system. The garbage gasification and biomass combustion integrated system comprises a gasification furnace and a circulating fluidized bed boiler. An inner container is arranged in the gasification furnace. A pulverizing device for pulverizing garbage is arranged abovethe inner container. The gasification furnace is connected with a combustion chamber of the circulating fluidized bed boiler through a gas output pipe. The combustion chamber of the circulating fluidized bed boiler is internally provided with a scattering mechanism. The circulating fluidized bed boiler is connected with a drying furnace through a first smoke output pipe. The drying furnace is provided with a primary biomass feeding device and a secondary biomass feeding device, and the drying furnace is connected with a purification box through a second smoke output pipe. According to the garbage gasification and biomass combustion integrated system, the garbage is conveyed into the gasification furnace to be gasified, then, generated gas is conveyed into the circulating fluidized bed boiler to be combusted together with biomass, and generation of garbage toxic gas is greatly reduced; and the waste heat value is increased, comprehensive treatment is conducted on the garbage and the biomass, the treatment effect is improved, and the environment is better protected.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a comprehensive system of garbage gasification and biomass combustion. Background technique [0002] As we all know, incineration of municipal solid waste is better than landfill and composting. However, there are many problems in the incineration of municipal solid waste. For example, auxiliary fuel is required when the calorific value of the waste is low; the furnace temperature is low, and the toxic and harmful components such as dioxins cannot be completely decomposed and destroyed, which will cause secondary pollution. In my country, a huge amount of biomass such as crops, crop waste, wood, wood waste and animal manure is produced every year. Biomass waste, as a kind of solid waste, is an environmental pollutant that people must properly handle. Improper disposal will cause serious environmental pollution. Biomass waste has potential threats to regional water environment, a...
