Problems solved by technology

[0004] This garbage treatment process has the following disadvantages: 1) The garbage is transported to the treatment site without disinfection and deodorization treatment, which has a certain impact on the surrounding environment; 2) Multiple screenings are required to separately process the sorted waste plastics, and the process is complicated cumbersome, increase equipment cost
3) The pressure requirements (6-12MPa) and temperature requirements (100-300°C) are high, the energy consumption is large, and the energy consumption cost is high
4) The equipment processing time (3.0-3.5 hours) is long and the processing capacity is low

Embodiment Construction

[0018] The structure of the high-pressure steam catalytic hydrolysis treatment device used in the present invention is shown in FIG. 2 . The device is composed of a cooking kettle, a stirring shaft, a stirring blade and a blade plate. Its structure is shown in Figure 1, wherein, cooking kettle 5 is marquis shape, and left and right ends is provided with sealing cover 8, and middle upper part is provided with feed inlet 6, and middle lower part is provided with discharge outlet 7, and feed inlet 7 and discharge outlet 8 are equipped with ball valves, which are used to seal and control the feeding port and the feeding port; the stirring shaft 1 is located in the center of the cooking kettle 5, and the two ends are fixed on the inner center of the sealing cover at both ends of the cooking kettle. There are 3-5 sets of stirring blades, basically Evenly installed on the stirring shaft 1, each set of stirring blades is divided into two upper and lower blades, one is the longer blade...

Abstract

The invention relates to a method for treating life waste. Wherein, it uses high-pressure steam catalyst hydrolysis processor; and the treatment comprises that: first using high-pressure steam treated chip condensed liquid to disinfect the waste; then classifying and selecting to picking the un-treated waste as glass, metal and rubber, and the ones which can be recycled; breaking left organic waste and feeding into high-pressure steam catalyst hydrolysis processor; chemically reacting at certain pressure, temperature and saturated steam, the energy generated in water molecule structure change will break off the molecule chain of macromolecule polymer, to reduce it into micromolecule polymer which can be absorbed by plant.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a domestic garbage treatment method. Background technique [0002] At present, the output of municipal solid waste is large, the density is high, and the water content is as high as 40-60%, and classified collection has not been implemented. However, some foreign waste treatment equipment has special requirements on the characteristics of waste, and is not suitable for treating domestic waste in China. The traditional landfill and incineration technologies will cause secondary pollution. Landfilling occupies a large amount of land, destroys the soil structure, and will expand infinitely, resulting in the phenomenon of garbage siege. The incineration method requires a large investment and the technology is immature. Composting needs to effectively classify organic matter and inorganic matter, but our country's municipal waste has not yet been classi...
