Problems solved by technology

Representative pyrolysis processes include rotary kiln process, vacuum moving bed process, two-stage moving bed process, and fluidized bed pyrolysis process. The above-mentioned technologies have the disadvantages of strict requirements on the particle size of raw materials, low processing capacity, and high difficulty in operation.
Moreover, waste pyrolysis oil is highly viscous, complex in composition, and low in calorific value, making it difficult to further utilize it. At the same time, these pyrolysis oils will also block pipelines and affect the normal operation of production
[0004] Therefore, the system and method for the treatment of domestic waste need to be studied

Embodiment 1

[0073] Using domestic waste from a certain city as raw material, the water content of the waste is 55%, and its composition is shown in Table 1, for reference Figure 7 , using the domestic waste to generate electricity, the specific steps are as follows:

[0074] Table 1 Household garbage composition (wt%)

[0075]

[0076] (1) Household waste is sent to the feeding device through the conveying system, and the feeding device feeds the material to the rotary bed pyrolysis furnace distribution area through the feeding port, and picks out large pieces of inorganic matter, such as bricks, stones, and large pieces, during the transportation process Glass and metal products, etc.

[0077] (2) Drying and pyrolysis of domestic waste: The main equipment for pyrolysis is a non-heat carrier regenerative rotary bed pyrolysis furnace, which includes a rotary bed pyrolysis furnace, a regenerative gas radiant tube burner, and cloth, outlet Auxiliary agencies such as materials. The botto...

Abstract

The invention discloses a power generation system and a power generation method. The power generation system generates power through using household garbage, and comprises a pyrolysis furnace, a combustion chamber, a waste heat boiler and a power generation device, wherein the pyrolysis furnace is used for pyrolyzing the household garbage, so as to obtain pyrolytic oil gas and pyrolytic carbon; the pyrolytic oil gas comprises pyrolytic oil and pyrolytic gas; the combustion chamber is connected with the pyrolysis furnace, and is used for performing direct combustion treatment on the pyrolytic oil gas, so as to obtain smoke; the waste heat boiler is connected with the combustion chamber, and performs heat exchange treatment through using the water vapor smoke and water in the waste heat boiler, so as to obtain superheated steam and cooled smoke; and the power generation device is connected with the waste heat boiler, and generates power through using the superheated steam. The power generation system provided by the embodiment of the invention has the advantages of simple structure, high thermal efficiency and low energy consumption.

Description

technical field [0001] The invention relates to a system and a method for generating electricity by using domestic garbage. Background technique [0002] With the rapid development of the economy, the continuous growth of the population and the improvement of people's living standards, the generation of domestic waste in China has also increased sharply. At present, the annual production of domestic waste in China is about 250 million tons, and it is still about 5% per year. The speed of growth has caused a great burden on the environment. Two-thirds of the large cities in the country are facing the dilemma of "garbage siege". [0003] At present, landfill and composting methods commonly used in waste disposal have fallen into the dilemma of occupying a large amount of land and composting products are unmarketable, while waste incineration has always been unable to get rid of the problem of dioxin pollution. Garbage pyrolysis can decompose domestic garbage under anaerobic o...
