Description

The biological dewatered reactor drum of a kind of domestic refuse
Technical field
The utility model relates to the biological dewatered reactor drum of a kind of domestic refuse, is used for realizing the device of domestic waste moisture decrement and Biostatic, belongs to the domestic rubbish disposal field.
Background technology
China's domestic refuse water ratio is higher; This and residents'living habit, region, population composition etc. all have confidential relation; High-moisture percentage refuse lowers moisture if do not carry out pre-treatment; Then follow-up landfill, burning disposal etc. being had very big negative impact, is the key that improves the separation performance and the utilization of resources but therefore reduce the domestic refuse water ratio.
In the existing technology, stable aerobic composting process that adopt of domestic waste more, this technology can realize the reduction of moisture in the rubbish, but main purpose is that it is main stablizing with becoming thoroughly decomposed with organism, and the compost cycle is longer, generally mostly is 20d~30d.
In addition, it is better that heat drying is handled dehydrating effect, can water ratio be reduced to below 10%, and the processing cycle is short, and the shortest is that 1~2h can accomplish; But inferior position that should technology is external steam source need be provided, and investment is big, and energy consumption is high, and has the hidden danger of blast, and final product is of poor quality, uses in the domestic rubbish disposal field to be restricted.
