Embodiment 1

[0031] A method for dry treatment of garbage, the steps comprising:

[0032] (1) Pile the garbage in the greenhouse, and seal the greenhouse so that the moisture inside the garbage evaporates to the surface and reaches a saturated state;

[0033] (2) reduce the surface humidity of the garbage, so that the humidity on the surface of the garbage changes from the saturated state of step (1) to the unsaturated state;

[0034] (3) Repeat steps (1) and (2) until the moisture content in the garbage is reduced to 40-60%, add fermentation aids to the garbage, and continue to dry the garbage after turning over until the moisture content reaches the standard.

[0035] The greenhouse in step (1) is a film greenhouse, and the color of the film is black.

[0036] The method for reducing the surface humidity of the garbage in the step (2) is drying with waste heat of the garbage pyrolysis and carbonization system.

[0037] The waste heat drying method is as follows: the waste heat of the w...

Abstract

The invention provides a garbage drying treatment method. The method comprises the following steps: stacking garbage in a greenhouse, closing the greenhouse, evaporating water in the garbage to the surface of the garbage until the water reaches a saturated state, then reducing the humidity of the surface of the garbage, converting the humidity of the surface of the garbage from the saturated stateto an unsaturated state, repeating the previous steps until the water content of the garbage is reduced to 40-60%, adding a fermentation aid into the garbage, carrying out turning, and continuing todry the garbage until the water content reaches the standard. The invention further provides application of the garbage drying treatment method in garbage pyrolysis and gasification. Through adoptionof the garbage drying treatment method, only the greenhouse is needed, so construction cost is low, large complex equipment does not need to be purchased, and application and promotion are facilitated; and the method further uses heat generated by straw fermentation, and straw garbage treatment is completed while garbage drying is promoted.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a garbage drying treatment method and its application. Background technique [0002] The harmless treatment methods of traditional domestic waste mainly include sanitary landfill, composting and incineration. Sanitary landfill technology is marginalized due to large investment, large area and low degree of harmlessness. Garbage composting is limited due to increasingly complex components of waste and low level of classification and collection. Incineration technology is currently the fastest growing technology, but due to It is peroxygen combustion, which is easy to generate dioxin and a large amount of fly ash during the combustion process, causing secondary pollution to the environment, and urban incineration is developing towards large-scale and large-scale, with high investment and operation costs, and is not suitable for rural waste treatment . [000...
