Problems solved by technology

Moreover, they all have the disadvantages of heavy wear, heavy smoke and high energy consumption, which limit their scope of application and make it difficult to achieve ideal economic results.
In addition, although the fluidized bed incinerator has the advantages of uniform and stable combustion temperature, high combustion rate, compact structure, and less harmful gases, it must perform crushing pretreatment on primary domestic waste in advance, so it also restricts its wide application. application

Abstract

The invention discloses an integrated household refuse incineration treatment method. The method includes the steps of conducting waste water removal and drying on native household refuse through an MBT facility to obtain refuse physical water, dried refuse, dried waste gas and dried waste water; conducting winnowing and pelletization on the dried refuse to obtain pelletized refuse, the heavy object part of the dried refuse and pelletized waste gas; conducting incineration treatment on the pelletized refuse through an FBI facility or a grate furnace facility; conducting separation and purification on the heavy object part of the dried refuse through a renewable resource purification facility to obtain renewable resources and purified waste water, wherein the MBT is the mechanical biological treatment technology, and the FBI is the fluidized bed incineration technology. By means of the method, the treatment cost of household refuse can be reduced, economic benefits can be obtained, the amount of generated renewable resources is large, no secondary pollution is caused, and the expanding performance is good; in addition, the invention further provides a device used for the method.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an integrated domestic garbage incineration treatment method and equipment. Background technique [0002] The environmental pollution caused by municipal solid waste is one of the urgent problems to be solved in many countries. According to a report from China Environment News on December 30, 2014, China's municipal solid waste removal volume has reached 170 million in 2013. tons, with an average annual growth rate of about 2%. Municipal solid waste treatment directly affects people's quality of life, working environment and urban construction development. However, expensive traditional waste incineration power generation and heating plants hinder people's enthusiasm for investment and construction. [0003] At present, there are two types of common waste incineration power generation and heating plants in China, one is the grate furnace, and the other is the fluidized...
