Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal, and in particular to a garbage crushing mechanism of a garbage incineration generator set. Background Art

[0002] With the rapid development of the economy and the improvement of people's living standards, how to deal with the huge amount of domestic waste has become one of the serious problems. At present, there are three ways to deal with domestic waste: direct incineration, sanitary landfill and composting. Compared with landfill that is easy to cause secondary pollution and composting that is difficult to sell. During the incineration process of garbage, a large amount of heat will be generated. Using this part of the heat for power generation can achieve waste heat recovery and maximize the use of resources. Garbage incineration power generation mainly uses the heat released by the combustion of garbage to heat water to obtain superheated steam. The expansion of superheated steam drives the turbine to rotate, which in turn drives the generator to generate electricity. In order to make domestic garbage burn more fully, the garbage is generally crushed before burning, thereby increasing the contact area between the garbage and the air and improving the efficiency of garbage combustion.
