Problems solved by technology

Both methods of composting and garbage recycling require people to separate organic waste from other waste. It has a good development prospect, but due to the incomplete process, there are phenomena such as dust flying and bad smell in the process. It pollutes the working and living environment to varying degrees, and the resource recovery rate is not high

Embodiment Construction

[0017] The present invention will be further described below in conjunction with embodiment.

[0018] A sanitary comprehensive treatment method for municipal solid waste, comprising the following steps:

[0019] (1) Send the collected municipal solid waste into the kettle body of a circular tubular sanitary heat-conducting kettle with internal opening and external sealing, and a plow rack protruding toward its axis is arranged in the kettle, and the plow rack follows the kettle body forward or Reverse rotation, one of the functions of the protruding plow rack is to facilitate the turning of garbage in the kettle, the second function is to facilitate the crushing of garbage materials, and the third function is to facilitate the output of garbage from the kettle; Forward or reverse rotation; the sanitary heat conduction kettle adopts a suspended horizontal installation, and the angle between its axis and the horizontal line is less than 5 degrees and greater than 2 degrees, and ...

Abstract

The invention discloses a method for comprehensively processing municipal solid waste. The method is characterized by no incineration, no landfill, no manual sorting, high degree of automation processing, closed-loop compound processing, coherent and uninterrupted processing, no garbage leakage, no secondary pollution and high recycling rate of resources. In the process, garbage is uniformly heated by heating a hygienic heat conducting kettle and transmitting steam through an external heat source. In this way, the garbage is effectively carried out disinfection, sterilization, dehydration and reduction under the hypoxic conditions. The afterheat produced by an external heat resource is used for electricity generation and production at the next process. The effective resources after processing, such as inorganic materials, organic materials and plastics, etc. are recycled. The method for comprehensively processing municipal solid waste has large amount of waste processing, low investment, energy conservation, discharge reduction and environmental protection.

Description

technical field [0001] The invention relates to a method for treating municipal domestic garbage, in particular to a sanitized comprehensive treatment method for urban domestic garbage. Background technique [0002] At present, the treatment methods of municipal solid waste are (1) throwing away on land; (2) throwing away at sea; (3) landfill; (4) sanitary landfill; (5) incineration; (6) composting; (7) recycling Take advantage, wait. Among them, throwing garbage directly into land, ocean or river is the most primitive and most undesirable. Doing so is not only unhygienic and does not reduce capacity, but also causes secondary pollution, destroys the ecological balance, and causes endless troubles. Direct landfilling is a great waste of precious land resources. It not only pollutes land and water in the environment, but also poses a threat to human living environment and health. Landfill garbage can only be purified after 20 years. The pollution of the changed flooding are...
