Embodiment

[0030] Such as Figure 6 Shown, a kind of municipal solid waste comprehensive treatment process of the present invention, it is specifically realized by the following steps.

[0031] 1. Crushing pretreatment: The garbage truck transports the original municipal solid waste to the site, and the garbage is unloaded into the garbage bin 1, and put into the crusher 3 through the grab bucket 2 for rough crushing, and the crushed garbage enters through the chute The crushing area of ​​the garbage bin 1; the garbage bin 1 is equipped with a micro-negative pressure device, and the micro-negative pressure device transports the irritating gas in the garbage bin 1 to the air preheater 10 in the subsequent step through the exhaust fan for preheating , prevent the odor in the garbage silo 1 from escaping. The bottom surface of the garbage silo 1 has a certain inclination (the slope can be 2% to 5%), and a leachate collection and drainage device is installed at the lowest point of the botto...

Abstract

The invention discloses a municipal solid waste comprehensive treatment technology, comprising the following steps of crushing, sterilized dehydration, sieving, burning and flue gas purification, wherein the high-temperature flue gas generated after burning is used for heating steam to form high-temperature steam in a steam heater; the high-temperature steam is used for providing heat energy to the sterilized dehydration step; and low-temperature steam formed by carrying out heat exchange to the high-temperature steam in the sterilized hydration step is mainly refluxed to the steam heater for the next round of circulation treatment by absorbing the heat energy of the high-temperature flue gas again. The treatment technology provided by the invention has the advantages of sufficient resource utilization, energy saving, environment friendliness, good effect of waste comprehensive recovery treatment, and capability of effectively solving the pollution problem caused by municipal solid wastes.

Description

technical field [0001] The invention relates to a treatment method for solid waste, in particular to a treatment process for municipal domestic waste. Background technique [0002] At present, domestic waste disposal mainly includes several methods such as landfill, incineration, and classified treatment. These methods have serious shortcomings such as large investment, large land occupation, and secondary pollution, so that most of the municipal solid waste in my country can only be treated by stacking. This simple stacking method is easy to breed bacteria due to its land occupation. And defects such as producing corrupt gas are affecting our living environment and quality of life more and more seriously. [0003] CN1426856A Chinese patent document discloses a treatment method of domestic waste, which includes magnetic separation, wet digestion and other process steps; it uses a digestion tank to digest the garbage, but the digestion tank needs to be filled with about 0.9MP...
