Description

Technical Field

[0001] This utility model relates to a waste storage structure for a waste incineration power plant, and in particular to a negative pressure storage and deodorization system for waste. Background Technology

[0002] In waste-to-energy plants, the waste storage silo is a large, open or semi-open concrete structure used for the temporary storage and fermentation of waste. The waste storage silo is the primary source of odor pollution in the entire plant. Currently, the common method is to set the waste storage silo under negative pressure, drawing the odorous gases to an external deodorization filter for deodorization and filtration before release, or drawing the odorous gases into the incinerator as combustion air. However, due to the enormous size of the waste storage silo, a single extraction point cannot create a uniform and stable negative pressure throughout the space, resulting in insufficient negative pressure near openings such as the unloading gate, leading to odor leakage. Therefore, existing technologies suffer from the problem of odor leakage at the unloading point. Summary of the Invention

[0003] The purpose of this invention is to provide a negative pressure storage and deodorization system for waste. This invention effectively reduces odor leakage at the discharge port.

[0004] The technical solution of this utility model is as follows: a negative pressure storage and deodorization system for waste, including a negative pressure waste storage bin, with multiple negative pressure collection pipes on the top of the negative pressure waste storage bin, and the unloading channel of the negative pressure waste storage bin having two sealed roller shutter doors, with a channel adsorption hood on the inner side of the outer sealed roller shutter door and a negative pressure gas collection hood on the inner side of the inner sealed roller shutter door. Both the channel adsorption hood and the negative pressure gas collection hood are connected to negative pressure branch pipes; it also includes a filter deodorizer located outside the negative pressure waste storage bin, the filter deodorizer being connected to a negative pressure main pipe via a negative pressure fan, and the negative pressure main pipe being connected to the negative pressure collection pipes and negative pressure branch pipes respectively.

[0005] In the aforementioned negative pressure storage and deodorization system for waste, the bottom of the negative pressure waste storage bin is provided with a leachate ditch, the upper part of the leachate ditch is provided with a long strip grating plate, the long strip grating plate is provided with a set of through grating openings, the long strip grating plate is provided with a hollow negative pressure cavity, one end of the hollow negative pressure cavity is provided with a negative pressure pipe, and the negative pressure pipe is connected to the negative pressure main pipe; the lower surface of the long strip grating plate between adjacent through grating openings is provided with a set of evenly distributed negative pressure holes.

[0006] In the aforementioned negative pressure storage and deodorization system for waste, the negative pressure collection pipe is connected to multiple negative pressure collection ports.

[0007] Compared with existing technologies, this invention features multiple negative pressure collection pipes installed at the top of the negative pressure waste storage chamber, two sealed roller shutters (inner and outer) within the unloading channel, a channel adsorption hood inside the outer sealed roller shutter, and a negative pressure gas collection hood inside the inner sealed roller shutter. These are connected to an external filter deodorizer and negative pressure fan via pipelines, achieving negative pressure adsorption within the negative pressure waste storage chamber. It also enhances localized sealing and negative pressure adsorption, effectively reducing odor leakage at the unloading port. In summary, this invention effectively reduces odor leakage at the unloading port. Attached Figure Description

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0011] Example. A negative pressure storage and deodorization system for waste, configured as follows: Figure 1-3 As shown, the system includes a negative pressure waste storage bin 1, with multiple negative pressure collection pipes 2 on the top of the bin 1. The unloading channel of the bin 1 has two sealed roller shutters 3, one inside and one outside. The outer sealed roller shutter 3 has a channel adsorption hood 4 on its inner side, and the inner sealed roller shutter 3 has a negative pressure gas collection hood 5 on its inner side. Both the channel adsorption hood 4 and the negative pressure gas collection hood 5 are connected to negative pressure branch pipes 6. The system also includes a filter deodorizer 7 located outside the bin 1. The filter deodorizer 7 is connected to a negative pressure main pipe 9 via a negative pressure fan 8. The negative pressure main pipe 9 is connected to the negative pressure collection pipes 2 and the negative pressure branch pipes 6, respectively.

[0012] The bottom of the negative pressure waste storage bin 1 is provided with a leachate ditch 10, and the upper part of the leachate ditch 10 is provided with a long strip grating plate 11. The long strip grating plate 11 is provided with a set of through grating openings 12. The long strip grating plate 11 is provided with a hollow negative pressure cavity 13. One end of the hollow negative pressure cavity 13 is provided with a negative pressure pipe 14, which is connected to the negative pressure main pipe 9. The lower surface of the long strip grating plate 11 between adjacent through grating openings 12 is provided with a set of evenly distributed negative pressure holes 15.

[0013] The negative pressure collection pipe 2 is connected to multiple negative pressure collection ports 16.

[0014] Since some of the odor in the waste storage bin originates from leachate, which is located at the bottom of the bin, and negative pressure adsorption pipes are generally laid at the top of the negative pressure storage bin, their adsorption effect on the odor emitted from the leachate at the bottom is not strong. To solve this problem, this application also improves the grating plate at the top of the leachate ditch at the bottom of the negative pressure storage bin, making it a negative pressure odor adsorption structure with a hollow negative pressure cavity inside, negative pressure holes connected on the lower surface, and negative pressure pipes at the ends. This achieves source capture of leachate odor and prevents it from spreading to the entire waste pit.

[0015] The negative pressure adsorption process of this utility model is as follows: the negative pressure fan works to adsorb the odor from the negative pressure collection pipe and negative pressure gas collection hood at the top of the negative pressure garbage storage bin into the negative pressure main pipe. At the same time, the negative pressure pipe at the bottom also draws the odor from the leachate ditch drawn in through the negative pressure hole and the hollow negative pressure cavity into the negative pressure main pipe. All the odor is filtered and deodorized by the filter deodorizer before being discharged.

[0016] When a vehicle enters the unloading channel to unload, the outer sealed roller shutter door is opened first. After the vehicle enters the unloading channel, the outer sealed roller shutter door is closed, and the inner sealed roller shutter door is opened. At the same time, the channel adsorption hood and negative pressure gas collection hood begin to adsorb odors, and the vehicle begins unloading. After unloading is completed, the inner sealed roller shutter door is closed, and the outer sealed roller shutter door is opened, which effectively reduces odor leakage.

[0017] The adsorption process of the long strip grille: The negative pressure air in the negative pressure pipe is located in the hollow negative pressure cavity, which draws in the odor through the negative pressure holes, through the hollow negative pressure cavity, and finally out through the negative pressure pipe. The hollow negative pressure cavity is connected throughout the long strip grille, except for the area separated by the through grille opening (the through grille opening is connected vertically, but not horizontally).
