Description

Technical Field

[0001] The utility model relates to the technical field of biogas slurry treatment, in particular to a carbon reduction device for kitchen biogas slurry. Background Art

[0002] Restaurant biogas refers to the organic waste liquid produced by the fermentation of restaurant kitchen waste, which is usually rich in organic matter and nutrients. This biogas can be used as an organic fertilizer for fertilizing farmland, which can improve soil texture, increase soil fertility, and promote plant growth. By rationally utilizing restaurant biogas, it is also possible to realize the resource utilization of organic waste and reduce environmental pollution. Among them, deamination treatment is an important step in biogas treatment. For example, in the announcement number CN106315726B, the biogas is decarbonized by a decarbonization tower during deamination treatment, which is an important step to increase the pH value of the biogas, and remove part of the carbon dioxide dissolved in the biogas (in the form of HCO3 - 、CO3 2- ion form), which increases the pH value of the biogas slurry (above 9.0), and the NH4+ in the biogas slurry is converted into volatile NH3, which is then carried out by water vapor in the subsequent deammoniation tower.

[0003] However, in order to make the biogas slurry contact with the filler more fully, the existing decarbonization towers mostly use spraying to spray the filler. However, the kitchen biogas slurry usually contains a certain amount of suspended matter and organic matter. If these substances enter the decarbonization tower, they may cause blockage to the nozzles and other equipment, affecting the spraying effect.

[0004] Therefore, we proposed a kitchen biogas slurry carbon reduction device to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3As shown, the utility model provides a decarbonization device for kitchen biogas slurry, including a decarbonization tower body 1, a partition 2, a filler 3, a blower 4, an exhaust pipe 5, a spray head 6, a filter screen 7 and a self-cleaning mechanism 8. The top of the tower body 1 is provided with a liquid inlet pipe 11 for feeding kitchen biogas slurry, and the bottom thereof is provided with a liquid outlet pipe 12 for discharging the biogas slurry after decarbonization. The partition 2 is arranged above the inside of the decarbonization tower body 1, and the inner cavity of the decarbonization tower body 1 is divided into a liquid storage chamber 13 and a reaction chamber 14. The liquid storage chamber 13 is located above the partition 2 and is used for temporarily storing biogas slurry. The reaction chamber 14 is located above and below the partition 2 and is used for blowing off carbon dioxide in the biogas slurry. The reaction chamber 14 is provided with a liquid storage chamber 13 and a reaction chamber 14. A packing 3 is arranged, and a blower 4 is on one side of the decarbonization tower body 1. An outlet pipe 10 located at the bottom of the reaction chamber 14 is arranged at the outlet end of the blower 4. A plurality of nozzles arranged on the outlet end are arranged on the outlet pipe. An exhaust pipe 5 with one end extending to the outside of the decarbonization tower body 1 is arranged on the upper part of the reaction chamber 14. A plurality of spray heads 6 are arranged on the partition 2. The plurality of spray heads 6 are evenly distributed on the partition 2 in a circular array. The bottom of the spray head 6 and the reaction chamber 14 extend into the reaction chamber 14. The top of the spray head 6 extends into the liquid storage chamber 13. A filter screen 7 is arranged at the water inlet at the top of the spray head 6. A self-cleaning mechanism 8 for scraping off blockages in the filter screen 7 is arranged on the top of the partition 2.

[0025] like Figure 2 and Figure 3 As shown, the self-cleaning mechanism 8 includes a rotating rod 81, a base 82, a conical block 83, a spiral piece 84, a scraping rod 85 and bristles 86. The rotating rod 81 is rotatably installed in the center of the partition 2, and the base 82 is fixed on the top thereof. The top of the base 82 is provided with a conical block 83 located directly below the liquid inlet pipe 11, and the side wall of the conical block 83 is provided with at least four spiral pieces 84. The side wall of the base 82 is provided with multiple scraping rods 85, and the bottom of the scraping rod 85 is provided with bristles 86 that fit with the filter 7.

[0026] When the biogas slurry is decarbonized, it first enters the liquid storage chamber 13 through the liquid inlet pipe 11 for temporary storage. Before entering the spray head 6, it is filtered by the filter 7 to prevent suspended matter from entering the spray head 6, causing it to be blocked and difficult to clean. The blocked suspended matter accumulates on the surface of the filter 7, and the self-cleaning mechanism 8 cleans the accumulated suspended matter to prevent it from clogging the filter. The cleaning process of the self-cleaning mechanism 8 is as follows:

[0027] When the biogas slurry enters the liquid storage chamber 13 from the liquid inlet pipe 11, it impacts the conical block 83, and cooperates with the spiral piece 84 to drive the base 82 to rotate. When the base 82 rotates, it drives the scraping rod 85 and the bristles 86 to rotate. When the bristles 86 pass through the water inlet at the top of the sprinkler head 6, they scrape off the suspended matter accumulated on the filter screen 7.

[0028] As a preferred technical solution of the present utility model, the bristles 86 are interference fit with the filter screen 7 to improve the cleaning effect of the filter screen 7.

[0029] As a preferred technical solution of the utility model: a deepening cleaning mechanism 9 is arranged at the bottom of the scraping rod 85, and the deepening cleaning mechanism 9 includes a mounting plate 91 arranged below the scraping rod 85, and a plurality of reset springs 92 are arranged between the mounting plate 91 and the bottom wall of the scraping rod 85, and the bristles 86 are fixed to the bottom of the mounting plate 91, and extension plates 93 are arranged on both sides of the mounting plate 91, and a magnetic strip 94 is fixed in the extension plate 93, and a magnetic ring 95 with a magnetic pole opposite to that of the magnetic strip 94 is fixed on the top of the spray head 6. When the scraping rod 85 passes over the top of the spray head 6, the magnetic strip 94 and the magnetic ring 95 attract each other, so that the reset spring 92 stretches, and the mounting plate 91 drives the bristles 86 to move downward, and the mesh of the filter screen 7 is inserted and swept, thereby further improving the cleaning effect of the filter screen 7.

[0030] As a preferred technical solution of the utility model: the outlet pipe 10 is a disc-shaped pipe, and a plurality of nozzles are evenly distributed on the upper part of the outlet pipe 10. The structure of the disc-shaped pipe makes the air intake more uniform, so as to improve the denitrification effect on the biogas slurry.
