Embodiment Construction

[0030] Below in conjunction with process flow sheet, the present invention is described in further detail:

[0031] (1) Solidification of garbage

[0032] After the daily fresh domestic garbage is transported to the solidification site, the plastic bags must first be cracked for the garbage in plastic bags. In the prior art, special bag breaking equipment is generally used for cracking. There is still 120°C-140°C generator exhaust to break the plastic bags packed in garbage bags, so that the broken plastic bags and garbage enter the open sorting conveyor belt in a scattered state; then, the plastic, glass, Hard products such as rubber, tires, and wood are sorted out, and the metal is sucked out by a magnetic separator; then the sorted garbage is crushed into a block fiber with a length of about 10mm by a pulverizer; Generator tail gas, drying, evaporating and pulverizing the moisture of blocky garbage, so that the water content of daily fresh domestic garbage is about 50% and...

Abstract

A comprehensive utilization method for secondary power generation by solid waste solidification and gasification process, comprising the following steps: 1) solid waste solidification: turning domestic waste into dense and hard solid waste rods; (2) waste gasification: solid waste rods Add anti-fire gasifier dry distillation to generate combustible gas; (3) Gasification power generation: supply the generated combustible gas to the internal combustion generator for power generation; (4) Secondary power generation: collect the waste heat of the internal combustion generator, and send it to the low-pressure boiler to generate steam, The generated steam is used to drive the low-pressure steam generator to generate electricity to achieve secondary power generation; (5) slag utilization; (6) waste heat utilization, using the waste heat of the low-pressure steam generator to break open the plastic bags of garbage and dry the garbage moisture. The present invention has the advantages of high recycling rate of domestic waste, no secondary pollution, less project investment, etc., solves the problem of waste leakage pollution, the odor problem caused by the centralized stacking of waste, and the problem of mass production of dioxin, and creates a new A precedent for secondary power generation from domestic waste.

Description

technical field [0001] The invention relates to a treatment method for comprehensive utilization of solid waste resources, in particular to a method for comprehensive utilization of solid waste solidification and gasification for secondary power generation. technical background [0002] Solid waste with domestic garbage as the main component is a major source of pollution that destroys the ecological balance of the human living environment. In particular, the harmful components produced by a large amount of exposed domestic garbage in cities and towns have caused serious pollution to the atmosphere, water, soil, and humans and animals. [0003] With the acceleration of urbanization, the expansion of urban population, the improvement of citizens' consumption level, and the increase of the amount of solid packaging materials, the output of urban domestic waste is increasing year by year. The pollution caused by this domestic waste has become a major pu...
