Because the prior wet garbage treatment is mainly landfilled or incinerated, no technical scheme for treating the wet garbage through hydrothermal oxidation reaction exists, and correspondingly, no reaction kettle specially providing hydrothermal oxidation reaction environment for treating the wet garbage exists. Therefore, the reaction kettle of the utility model can meet the demand of adopting hydrothermal oxidation reaction to treat wet garbage.

The wet garbage refers to perishable garbage, also called kitchen garbage and organic garbage, and includes but is not limited to perishable biomass domestic wastes such as food material waste, leftovers, expired food, melon peel and fruit stones, green plants of flowers, traditional Chinese medicine dregs and the like. The wet garbage is mainly derived from garbage generated in activities such as daily life, food processing, diet service, unit catering and the like of residents, and comprises abandoned vegetable leaves, leftovers, fruit peels, eggshells, tea residues, bones, animal viscera, fish scales, leaves, weeds and the like.

The hydrothermal oxidation technology is a novel chemical oxidation method, and is generally carried out in a water environment with the temperature of 100-. Through hydrothermal reaction, the household garbage such as kitchen waste and kitchen waste can be quickly converted into organic fertilizer raw materials (humic acid), and the purpose of recycling the garbage is further achieved. After the reaction is finished, the obtained filtrate contains organic matters and can be used as an organic fertilizer for greening or gardening; the filter cake obtained by filtering is rich in humic acid and can be used as an organic fertilizer for improving soil.

Before the hydrothermal oxidation technology is performed, the wet garbage can be subjected to pulping treatment to obtain wet garbage slurry, and the hydrothermal oxidation reaction is performed on the wet garbage slurry. For example, the wet waste may be sorted to remove metal, glass, or plastic products, etc. therefrom; crushing the sorted wet garbage by using a single-stage or multi-stage crusher; emulsifying the crushed wet garbage and water to obtain the wet garbage slurry. For example, in the emulsification process, the ratio of the crushed wet garbage to water can be 1: 1-1: 2.

those skilled in the art will appreciate that the method of making the wet waste slurry is not limited and that the above method is exemplary only. The wet waste slurry resulting from the emulsification of water and wet waste can be made in other ways by those skilled in the art.

As shown in fig. 1 and 2, the embodiment of the present specification provides a wet waste treatment reaction kettle, comprising a reaction cylinder 10, a stirring device 20 and a filtering device 30, wherein the stirring device 20 is installed in the reaction cylinder 10 for stirring and heating wet waste slurry, and the filtering device 30 is installed in the reaction cylinder 10 for filtering organic fertilizer obtained by reaction.

Specifically, the reaction cylinder 10 has a slurry inlet 11, a solid fertilizer outlet 12, a liquid fertilizer outlet 13, and a reaction chamber 14. The slurry inlet 11 is arranged on the top wall 151 of the reaction cylinder 10, is communicated with the reaction cavity 14, and is used for discharging the wet garbage slurry into the reaction cavity 14 for reaction. The solid fertilizer outlet 12 and the liquid fertilizer outlet 13 are disposed on the bottom wall 152 of the reaction cylinder 10, and are communicated with the reaction chamber 14 for discharging the solid fertilizer and the liquid fertilizer obtained by reaction respectively.

In practical applications, a person skilled in the art can install flanges on the slurry inlet 11, the solid fertilizer outlet 12 and the liquid fertilizer outlet 13, respectively, and connect the reaction kettle with a wet garbage slurry manufacturing device, a solid fertilizer bagging device and a liquid fertilizer processing device, respectively, so as to facilitate the input of wet garbage slurry and the discharge of solid and liquid fertilizers.

The stirring device 20 comprises a hollow shaft 21 and a stirring paddle 22, wherein the stirring paddle 22 extends radially outward from the hollow shaft 21, the hollow shaft 21 is installed in the reaction cylinder 10 in a driving way, and when the hollow shaft 21 is driven to rotate, the stirring paddle 22 is driven to rotate to stir the wet garbage slurry.

The hollow shaft 21 is hermetically connected to the peripheral wall 15 of the reaction cylinder 10, so as to form a sealed reaction environment and prevent the wet garbage or the odor generated during the reaction from being released.

Further, the hollow shaft 21 is provided with a heat medium cavity 211 for circulating heat media such as heat transfer oil or steam, so as to uniformly heat the wet garbage slurry and provide reaction conditions for hydrothermal oxidation reaction. An external heat medium production device inputs the heat medium into the heat medium cavity 211, and the heat medium radiates heat into the reaction cavity 14 by means of the hollow shaft 21 so as to be absorbed and utilized by the reaction generated in the reaction cavity 14.

Compared with a direct heating scheme, the problem that the organic fertilizer is likely to coke due to overhigh wall temperature of the reaction kettle can be solved by utilizing the heating medium in the hollow shaft 21 for heating.

Preferably, as shown in fig. 2, the stirring paddle 22 is a hollow stirring paddle, has a heat medium channel 221, and can also flow a heat medium such as heat conducting oil or steam, so as to uniformly heat the wet garbage slurry. The heat medium passage 221 of the stirring paddle 22 communicates with the heat medium cavity 211 of the hollow shaft 21. The heating medium flows into the heating medium passage 221 through the heating medium chamber 211.

Thus, when the stirring paddle 22 is driven to stir the wet waste slurry, the wet waste slurry can be uniformly heated by the heating medium, so as to provide reaction conditions for hydrothermal oxidation reaction, thereby achieving two purposes.

The paddles 22 may be implemented as an anchor, a straight blade, a dome open turbine, a flap open turbine, a propeller, a straight blade disk turbine paddle, etc., but the embodiment is not limited thereto, and those skilled in the art may select a suitable shape and size of the paddles.

Preferably, the stirring paddle 22 is implemented as a hollow helical stirring paddle, and axial flow is formed during stirring, so that the rotating radius is large, and the stirring range is wide. For example, the hollow helical stirring paddle may be a ribbon stirring paddle, and the helical stirring ribbon is fixed to the hollow shaft 21, for example, by fixing members respectively provided at both ends of the hollow shaft 21 and the helical stirring ribbon. In this case, the fixing element may also serve as a stirring element during operation, and the fixing element may also be hollow, so that the heating medium may flow through it.

Further, the filtering means 30 is installed at the bottom of the reaction chamber 14 in a flow path of the organic fertilizer to the solid fertilizer outlet 12 and the liquid fertilizer outlet 13. And when the reaction is finished, the organic fertilizer is obtained, solid-liquid separation is carried out on the organic fertilizer through the filtering device 30, the obtained liquid fertilizer flows to the liquid fertilizer outlet 13 for discharging, and the obtained solid fertilizer is discharged through the solid fertilizer outlet 12.

In one embodiment of the present description, as shown in the figures and fig. 2, the filtering means 30 is implemented as a conical sieve. The conical filter screen has a working state and a discharging state. The person skilled in the art can select different sieves or filter cloths depending on the material.

In the working state, the conical filter screen forms a filtering space, the top edge of the conical filter screen is fixed on the peripheral wall 15 of the reaction chamber 14, the filtering space is gradually reduced from top to bottom, the organic fertilizer enters the filtering space, and the solid and the liquid are separated through the conical filter screen.

When the fertilizer is in a discharging state, the conical filter screen is provided with a discharging hole 32, and the discharging hole 32 is communicated with the solid fertilizer outlet 12 and used for discharging the solid fertilizer. For example, the outlet 32 is disposed at the bottom of the conical filter, and in the working state, the outlet 32 is closed, and in the outlet state, the outlet 32 is opened.

In the working state, the liquid fertilizer outlet 13 can be opened first, and the filtered liquid fertilizer is discharged while the filtering work is performed. And after the filtering operation is finished, opening the solid fertilizer outlet 12 and discharging the solid fertilizer.

When the paddles 22 are implemented as helical ribbon paddles, the helical ribbon is adjacent to the perimeter wall of the filtration space, thereby facilitating scraping of solids from the conical screen. Like this, in the solid-state fertilizer ejection of compact in-process, the spiral shell belt stirring rake still can work, is convenient for scrape the ejection of compact with the solid-state fertilizer on the toper filter screen.

Further, the wet waste treatment reactor comprises a pressure control device 40, which is installed in the reaction cylinder 10 and is used for controlling the pressure in the reaction chamber 14. The present embodiment is not limited to the above-described embodiment, and the pressure control device 40 may be a conventional pressure controller.

In the reaction stage, the pressure control device 40 increases the pressure in the reaction chamber 14 and stabilizes the pressure in the reaction chamber 14 to a preset reaction pressure condition.

In the filtering stage, the pressure control device 40 reduces the pressure in the reaction chamber 14, so as to facilitate the discharge of the organic fertilizer. Preferably, the pressure control device 40 reduces the pressure in the reaction chamber 14 by flash evaporation, and cooperates with the filtering device 30 to filter-press the organic fertilizer, so as to obtain liquid fertilizer and solid fertilizer.

Further, in order to prolong the service life of the filtering device 30 and prevent the filtering device 30 from being damaged under high pressure, the wet waste treatment reaction kettle comprises a pressure balance pipe 50.
