Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0031] The process for integrated rapid carbonization treatment of urban waste includes the following steps:

[0032] (1) Garbage pretreatment: sort and recycle the construction waste such as stones and metal objects in the belt-treated waste, and use a crusher to crush the waste into particles with a particle size of 5-50mm to be processed;

[0033] (2) Removal of garbage liquid: send the crushed garbage into the distribution bin of the drying furnace, and the garbage is evenly distributed from the distribution bin to the conveyor belt in the drying furnace, and the garbage on the conveyor belt can be regulated and polymerized in the furnace Under the heating hood, it is quickly heated and dehydrated. The vaporized water in the garbage is pumped out by the induced draft fan and sent to the tail gas treatment station. The dehyd...

Abstract

The invention provides an integral rapid carbonizing treatment technology for municipal waste. The technology comprises steps of pre-processing the waste, removing waste liquid, smashing and dehydrating in a raw material bin, smashing and dehydrating in a feeding bin, drying the stored material, and splitting and carbonizing the waste. The whole treatment process has advantages of no escaped substance, no emission, high use ratio of heat energy, and large waste treatment capacity in a production process.

Description

technical field [0001] The invention relates to the field of urban garbage treatment, in particular to an integrated rapid carbonization process for urban garbage. Background technique [0002] With the rapid development of my country's economy, the expansion of city scale and the acceleration of urbanization process, the generation and accumulation of urban domestic waste in my country are also increasing year by year. In recent years, the annual growth rate of municipal solid waste has been 5%-8%, and the annual growth rate of waste in a few large cities has reached 8%-10%. The per capita daily waste production has exceeded 1 kg, which is close to the level of moderately developed industrial countries. The amount of urban waste generated in my country has shown a sharp increase, and the trend of growth is getting faster and faster. [0003] my country started relatively late in the treatment of urban domestic waste. For a long time, the main purpose of my country's ur...
