Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] figure 1 It is a flow chart of the kitchen waste pyrolysis treatment process. Garden waste is generally the branches or leaves that are naturally dropped by the city during the greening and pruning process or plants. Generally, shearing crushers are used for preliminary crushing. The size after crushing is ≤ 30mm; The broken garden waste is transported to the feed port of the screw conveyor by a forklift, and then transported to the storage pit by the screw ...

Abstract

The invention discloses a kitchen waste pyrolysis treatment technique which comprises the following steps: carrying out preliminary crushing on garden waste, and pressurizing kitchen waste for drainage; proportionally mixing, sending into a rotary reaction furnace, and pyrolyzing the waste mixture into vapor, pyrolysis gas, carbon, tar and dust; combusting the clean pyrolysis gas as a fuel to directly provide a heat source for rotary kiln reaction furnace pyrolysis equipment; and finally, cooling the high-temperature carbon generated by pyrolysis, and discharging, thereby completing the kitchen waste/garden waste mixed pyrolysis treatment. By using the indirect-heating rotary kiln pyrolysis equipment, the flue gas for heating the rotary kiln does not directly contact the pyrolysis materials, thereby enhancing the quality of the pyrolysis gas and enhancing the quality and yield of the carbon. The pyrolysis gas is washed and directly combusted to heat the rotary kiln, thereby requiring fewer pyrolysis auxiliary energy sources and lowering the operating cost.

Description

technical field [0001] The invention relates to a waste treatment process, in particular to a new process for mixing kitchen waste and garden waste through pyrolysis treatment. Background technique [0002] Kitchen waste refers to a kind of perishable domestic organic waste. Its main components are leftovers, leftovers, fruit peels, vegetable leaves, plastic bags, etc., and are composed of starch, cellulose, protein, lipids and inorganic salts. It mainly has the characteristics of high moisture content, perishability, and rich nutrients. If it is not treated in time, it will affect the living environment, produce stench, and the leachate will pollute surface water and groundwater. In addition, if it is not handled properly, it will also cause harm, such as feeding livestock, causing harmful substances to accumulate in various parts of the pig, and people eating such pork will endanger human health; if "gutter oil" is extracted by criminals and used as edible oil If eaten, ...
