Description

Technical Field

[0001] The invention relates to the technical field of composting equipment, and in particular to a green composting device for reducing the emission of polluted gases. Background Art

[0002] Composting is a process of mineralization and humification of organic waste under the action of microorganisms to achieve harmlessness of organic waste. However, the composting process usually produces a large amount of odor (such as NH3 and H2S) and greenhouse gases (CO2 and N2O, etc.). On the one hand, the odor will affect the living environment around the composting plant. On the other hand, under the background of the national development strategy of "dual carbon" and the reality of global warming, these have seriously affected the sustainable development of the composting industry and even agricultural production.

[0003] Among the existing related technologies, the Chinese utility model patent with the announcement number CN211111774U discloses a composting device with odor purification function, and the Chinese utility model patent with the announcement number CN214457684U discloses a film-covered strip stack type odorless composting device. However, the high-temperature sterilization mechanism, vacuum pump, 23UV lamp tube, etc. in the CN211111774U patent and the electric rope winding machine and odor induced draft fan in the CN214457684U patent increase the energy consumption of removing odor; although it can meet the deodorization effect, it is difficult to meet the demand for carbon reduction; and the deodorization materials and biological deodorization pools are difficult to achieve in-situ green treatment, which increases the subsequent treatment process. In order to solve the above problems, it is very necessary to develop a composting device with high composting efficiency, convenience, environmental protection and conducive to emission reduction and carbon reduction.

[0026] Among them, Figure 1 The main body of the cylinder 1 is a cylindrical cylinder, the top of which is movably connected to the arc-shaped top cover 4 through a connecting piece 10, and a cover plate 9 is connected to the top of the top cover 4 through a hinge. Fresh biological deodorant 24 can be put in by opening the cover plate 9. An exhaust pipe 7 is fixedly installed on the upper right of the top cover 4, and arc plates 25 are welded below and arranged obliquely on both sides. The bottom of the cylinder 1 is a prism-shaped bucket 2. The material enters the cylinder 1 through the feed port 5 on the upper right of the cylinder 1 and is composted inside. A pressure valve is installed inside the feed port 5. 6. The pressure valve 6 is kept closed to prevent the gas in the barrel from escaping. When a certain weight of composting raw materials enters the feed port 5, the pressure valve 6 will automatically open under the action of gravity; the inclined surfaces on both sides of the bucket 2 are provided with discharge ports 16, and the composting waste can be discharged by using its slope. The outer surface of the discharge port 16 is fixed with a bow-shaped handle 17 to facilitate the staff to open the discharge port 16; the bottom plane of the bucket 2 is provided with a circular hole for the air distribution pipe 14 in the cylinder 1 to pass through and connect with the blower 18 outside the composting device. Two "inverted L"-shaped metal legs, the support frame 3, are respectively provided on the left and right sides below the cylinder 1. They have a certain height to make the compost cylinder 1 off the ground, and universal wheels 20 are fixedly installed at the bottom of the metal legs to facilitate the movement of the compost cylinder 1.

[0027] The upper surface of the arc-shaped plate 25 can be evenly covered with a biological deodorant 24 that can absorb and purify the gas generated by the compost. Fresh biological deodorant 24 can be evenly placed on the upper surface of the arc-shaped plate 25 by opening the cover plate 9. Annular baffles 28 are welded on both sides of the center of the upper surface of the arc-shaped plate 25 to prevent the biological deodorant 24 from sliding down and accumulating. The exhaust pipe 7 can provide an escape path for the gas generated by the compost. The exhaust pipe 7 is also equipped with a cap 8 to prevent the gas from escaping at will. After removing the cap 8, the exhaust pipe 7 can also be connected to a purification device to further process the gas. An electric door 27 in the shape of a square is provided on each of the left and right sides of the arc-shaped plate 25. It moves along the arc surface direction and opens upward to allow the biological deodorant 24 to fall. Otherwise, it is closed. Figure 2The electric switch 22 on the control panel 21 on the rear wall of the middle cylinder 1 realizes its control. The upper edge of the arc plate 25 is provided with exhaust holes 26 arranged along its outer edge, and the hole diameter is small, so that gas can escape while the biological deodorant 24 is difficult to pass through.

[0028] Among them, the upper end of the air distribution pipe 14 is fixedly connected to the support rod 11, and the support rod 11 is horizontally fixed in the middle and upper part of the cylinder 1. The left and right ends of the support rod 11 are fixed by fixing screws 13, and a support rod sleeve 12 is provided to provide support for the air distribution pipe 14. The surface of the air distribution pipe 14 is evenly provided with air distribution holes 15, and the lower end passes through the bottom of the bucket 2 and is connected to an external blower 18 to provide oxygen and mixing power required for composting; a long-handled valve 19 is installed on the air distribution pipe 14 outside the cylinder 1 to control the air delivery volume. Three oxygen concentration sensors 23 are arranged at equal distances from top to bottom on the right side of the inner wall 1 of the cylinder to measure the oxygen content at different positions in the cylinder 1, and the measured oxygen concentration is displayed on the control panel 21 on the back of the cylinder 1.

[0029] The following practical operations further describe the invention.

[0030] Before using the composting equipment, after checking that the device is correct, close the top cover 4 and evenly spread the biological deodorant 24 on the upper surface of the curved plate 25 through the cover plate 9. When composting begins, the composting raw materials enter the cylinder 1 from the feed port 5 through the pressure valve 6, and the air volume of the blower 18 is controlled by the external long-handled valve 19. The air enters the air distribution pipe 14 to provide oxygen required for the growth, reproduction and metabolic activities of aerobic microorganisms during the composting process. At the same time, the wind stirring effect can accelerate the drying speed of the composting raw materials, and at the same time, the composting raw materials are fully contacted with oxygen and microbial fermentation agents, effectively improving the composting efficiency. An oxygen concentration sensor 23 is fixedly installed on the right side of the inner wall of the cylinder 1, and the measured data is displayed on the control panel 21; the gas generated by the composting enters the biological deodorizing device through the exhaust hole 26 opened on the curved plate 25 for deodorization and purification, and the purified gas is discharged through the exhaust pipe 7. When the composting process is finished, the ineffective biological deodorant 24 is dropped into the cylinder 1 by opening the electric door 27 on the arc plate 25 and directly used as composting raw material; the compost waste can be discharged by pulling the bow handle 17 to open the discharge port 16 below the bucket 2.
