Wet garbage treatment device and wet garbage treatment method

Abstract

The invention discloses a wet garbage treatment device and a wet garbage treatment method. The treatment device comprises a garbage can dumping machine, a garbage collector, a purification device, a garbage conveyor, a garbage crusher, and a garbage fermentation device, wherein the garbage can dumping machine has a structure for dumping a garbage can; the garbage collector has a structure for storing garbage and separating solids from liquid; the purification device at least has a structure which can output ozone-dissolved water into the garbage collector; the garbage conveyor has a structurefor discharging the garbage located in the garbage collector; the garbage crusher is connected to the garbage collector and has a structure for crushing the garbage in the garbage collector; and the garbage fermentation device is connected to the garbage crusher and at least has a structure for drying and outputting garbage slurry entering the garbage fermentation device. The wet garbage treatmentdevice has relatively high overall integration level, omits solid-liquid separation equipment and occupies a small area; and the purification device is used for generating water with a large amount of dissolved ozone for washing the garbage, can achieve the disinfection, sterilization, deodorization and the like with no need for additional substances, and has high purification efficiency, high purification quality and good environmental friendliness.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a wet garbage treatment device and a wet garbage treatment method. Background technique [0002] Wet garbage contains extremely high moisture and organic matter, which is easy to rot and produce bad smell. After proper treatment and processing, it can be transformed into new resources. The high organic matter content makes it possible to be used as fertilizer and feed after strict treatment, and can also produce biogas for fuel or power generation. The oil part can be used to prepare biofuels. [0003] For the treatment of wet garbage, such as a kitchen waste treatment device disclosed in the application number 201810470151.1, it passes through lifting and dumping equipment, conveying and crushing equipment, degreasing and desalting equipment, crushing equipment, solid-liquid separation equipment, fermentation equipment Treatment and utilization of domestic wast...

AI Technical Summary

Problems solved by technology

[0004] However, the overall structure of this device is complex, takes up a lot of space, and also has the following problems:

[0005] (1) The lifting structure provided uses a card frame to fix the trash can, but no specific implementation structure is given

[0006] (2) In addition, the existing cleaning method is water washing, and the effect of oil storage, desalination, sterilization and disinfection is not good

[0007] (3) The degreasing and desalting equipment of this scheme can only clean the garbage, but cannot clean the garbage can

[0008] (4) This plan adds a set of solid-liquid separation equipment, and the solid-liquid separation equipment adopts a vertical arrangement, with the feed port facing downward and the discharge port facing upward, and the screw propeller is used to transport the garbage upward. , the garbage will fall under its own gravity, which will inevitably reduce the efficiency of upward transportation; in addition, during the transportation process, a large amount of liquid will inevitably accumulate at the inlet 511 under the action of gravity and cannot be discharged, and even if the liquid in the garbage Being squeezed out, a large amount of water will not be discharged from the screen wall 512 and accumulate, therefore, its liquid often cannot be collected and discharged effectively

In addition, in this way, a screw conveyor needs to be set in the enclosure 54 to transport the material out, which obviously increases the complexity of the structure.
