Problems solved by technology

However, there is no relatively complete overall treatment system for kitchen waste
The materials used in the existing kitchen waste conveying devices are either not strong enough to meet the requirements, or the anti-corrosion performance is not up to the requirements, or the cost is too high. Therefore, it is urgent to propose a kind of material that is not too high in cost, but the strength and anti-corrosion performance meet the requirements. Required Conveyor Material

Embodiment 1

[0019] A method for harmless treatment of kitchen waste, characterized in that it comprises the following steps:

[0020] (1) Crushing, put the kitchen waste into the crushing device, and crush the kitchen waste so that the diameter of the crushed kitchen waste is not greater than 5cm, and the average diameter is 3.5cm.

[0021] (2) Dehydration. The crushed kitchen waste is transported to the dehydration device through the conveying device, and 80% of the water in the kitchen waste is removed by high-speed rotation. The speed of high-speed rotation is 1120 rpm. The solid matter after moisture removal is transported to the drying device through the conveying device, and the removed moisture flows into the water treatment device.

[0022] (3) Water treatment, the water removed through the dehydration step is decomposed and deodorized by oil, then layered and filtered to obtain reclaimed water for recycling.

[0023] (4) Drying. After the dehydrated solid matter is transported t...

Embodiment 2

[0028] A method for harmless treatment of kitchen waste, characterized in that it comprises the following steps:

[0029] (1) Crushing, put the kitchen waste into the crushing device, and crush the kitchen waste so that the diameter of the broken kitchen waste is not greater than 5cm, and the average diameter is 3.2cm.

[0030] (2) Dehydration. The crushed kitchen waste is transported to the dehydration device through the conveying device, and 80% of the water in the kitchen waste is removed by high-speed rotation, and the speed of high-speed rotation is 1100 rpm. The solid matter after moisture is transported to the drying device through the conveying device, and the removed moisture flows into the water treatment device.

[0031] (3) Water treatment, the water removed through the dehydration step is decomposed and deodorized by oil, then layered and filtered to obtain reclaimed water for recycling.

[0032] (4) Drying. After the dehydrated solid matter is transported to the...

Abstract

The invention relates to a harmless treatment method for kitchen waste, and belongs to the field of environment protection, in particular to the field of kitchen waste treatment. By means of reasonable matching of an overall kitchen waste procedure and specific parameters in specific procedures, the treatment efficiency of the kitchen waste and the material recycling completeness degree of the kitchen waste are improved.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to the field of kitchen waste treatment, and in particular relates to a harmless treatment method for kitchen waste. Background technique [0002] At present, landfill is the most common way to recycle kitchen waste, but with the increasing amount of waste, the disadvantages of landfill gradually appear, and because it contains a lot of organic matter, it is very easy to rot and deteriorate, and it is easy to produce waste after landfill. Biogas is prone to safety problems. At present, there are also some harmless treatment methods for kitchen waste. The main method is to crush it first, then dry and press it to form dry and relatively small waste. There are also many ways to produce biogas through microorganisms. However, there is no relatively complete overall treatment system for kitchen waste. The materials used in the existing kitchen waste conveying devices are eithe...
