Abstract

A pretreatment device for volume reduction and dehumidification of garbage, wherein: a compression chamber, a compression cutting device and a high-temperature and high-pressure steam engine are installed inside, one end of the compression cutting device is a hydraulic compression push rod, and the hydraulic compression push rod is connected to the feed port It is connected with the discharge port, and a punch is installed between the feed port and the discharge port; the bottom of the compression chamber is a wet carbonization tank, and a nano aeration disc is installed in the wet carbonization tank; a mesh belt is placed through the compression chamber In the inner, multi-time drying room and storage room, one end of the mesh belt is placed under the discharge port of the compression cutting device, and the other end of the mesh belt is placed in the storage room; heat exchangers are installed at the bottom of the multi-time drying room. The air inlet pipe is installed above the heat exchanger, and the air inlet pipe is connected with the heating fan; the return air pipe is installed on the top of the multiple drying chamber, and the return air pipe is connected with the dehumidification fan; the multiple drying chamber is located on the mesh belt Turning rollers are installed above each. The invention also discloses a method for pretreatment of urban garbage.

Description

technical field [0001] The invention relates to a device for reducing the moisture content of urban garbage, in particular to a pretreatment device for reducing volume and dehumidification of garbage. [0002] The invention also relates to a method for pretreatment of urban garbage by using the above-mentioned device. Background technique [0003] At present, the per capita annual output of urban garbage in my country has reached 440kg. In 2010, the amount of urban domestic garbage in my country reached 352 million tons, ranking first in the world, and it is growing at a rate of 8-10% every year. The annual storage of garbage has reached more than 6 billion tons. More than 100 cities are surrounded by garbage, and the land area occupied by garbage piles is as large as 750,000 mu. The problem of garbage has become a prominent problem that affects the quality of urban life. [0004] Waste treatment methods are mainly aerobic composting, anaerobic fermentation, incineration and...
