Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
The first embodiment is as follows:
as shown in figure 1, the kitchen waste and household waste incineration cooperative treatment device comprises a discharge hopper 1, a crusher 3, a solid-liquid separator 4, a three-phase separator 9, an incinerator 7 and a leachate treatment station 11, wherein the incinerator 7 and the leachate treatment station 11 are existing facilities of a household waste incineration plant.
Kitchen garbage is collected through receiving and carrying vehicle and is sent to discharge hopper 1 and save, and discharge hopper 1 bottom is equipped with first screw conveyer 2, and kitchen garbage carries to breaker 3 through first screw conveyer 2, that is to say, discharge hopper 1 communicates with the breaker through first screw conveyer 2. The kitchen waste is fully crushed by the crusher, the crushed particle size is smaller than 10mm, and materials generated by crushing are conveyed to the solid-liquid separator 4 through the second screw conveyor to generate first solid-phase waste and first liquid-phase waste.
A temporary storage groove 8 is communicated between the solid-liquid separator 4 and the three-phase separator 9 and used for storing the first liquid-phase garbage. Because the oil content in the first liquid phase garbage is higher and is about 1-2%, a heat exchange pipe is arranged in the temporary storage tank 8, the incineration plant steam 12 is introduced into the heat exchange pipe, the temperature in the temporary storage tank 8 is 70-80 ℃, namely, the incineration plant steam 12 is firstly utilized to heat the first liquid phase garbage when the subsequent oil-water separation is carried out, the heated first liquid phase garbage enters a three-phase separator 9 to be separated, and second solid phase garbage, second liquid phase garbage and grease are generated. Wherein, the grease is conveyed to the grease temporary storage tank 10 and can be sold as crude grease. Simultaneously, because kitchen garbage moisture content is higher, can produce the leachate in the 2 transportation process of first screw conveyer, consequently, first screw conveyer 2 and the groove 8 intercommunication of keeping in, leachate sends into the groove 8 of keeping in after collecting.
A liquid phase outlet (namely an outlet of the second liquid phase garbage) of the three-phase separator 9 is respectively communicated with the leachate treatment station 11 and the solid-liquid separator 4, namely, a small part of the second liquid phase garbage is sent to the solid-liquid separator 4 through a pipeline, the kitchen garbage is rinsed, grease is washed to a liquid phase as much as possible, and a large part of the second liquid phase garbage is sent to the leachate treatment station 11 through a pipeline.
The solid phase outlet (namely the outlet of the first solid phase garbage) of the solid-liquid separator 4 is communicated with a hopper 5, and the hopper 5 is simultaneously communicated with the solid phase outlet (namely the outlet of the second solid phase garbage) of the three-phase separator 9, namely, the first solid phase garbage and the second solid phase garbage are both conveyed to the hopper 5 through pipelines to be stored, and the moisture content of solid phase substances in the hopper 5 is about 70-80%. The inventor considers that the percolate treatment station 11 has no effect on removing grease basically, and the grease has great influence on membrane equipment in the percolate treatment station 11, and can block membrane holes to influence the normal operation of the equipment. Therefore, in order to avoid that kitchen waste grease and leachate enter the leachate treatment station 11 together in the garbage pit, the first solid-phase garbage and the second solid-phase garbage in the hopper 5 are conveyed to the upper part of the furnace inlet of the incinerator 7 through the plunger pump 6 and the pipeline, fall into the incinerator 7 under the action of gravity, and are subjected to incineration treatment, so that the problem that the leachate treatment station is difficult to treat the grease is solved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
