Description

Technical Field

[0001] The utility model relates to the technical field of garbage incineration treatment, in particular to a domestic garbage pretreatment device. Background Art

[0002] Waste incineration is currently the most commonly used method for harmless treatment of waste. It involves collecting the waste and then putting it into a waste incinerator for high-temperature and thorough incineration. Ash and exhaust gas are then obtained. After a series of harmless treatments of the exhaust gas, it can be directly discharged, while the ash can be centrally landfilled after subsequent treatment.

[0003] In order to improve the incineration efficiency of garbage, the garbage is usually pre-processed and broken down into relatively small volumes as much as possible through crushing and other methods, and then concentrated into a garbage incinerator for incineration.

[0004] It is found in actual use that domestic garbage often contains a large amount of waste liquid. The existing garbage pretreatment equipment can only crush the garbage, but cannot treat the waste liquid contained in the garbage, resulting in a high liquid content in the garbage put into the incinerator, which has a certain impact on the incineration effect; moreover, the existing garbage pretreatment device only has a crushing function, and cannot harmlessly treat the garbage leachate, resulting in a large amount of harmful gases and harmful leachate generated during the garbage treatment process, which seriously corrodes the equipment, and the harmful gases will pollute the environment and affect the health of the staff.
