Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a cooling and deodorizing device for municipal solid waste incineration slag. Background Technology

[0002] After municipal solid waste is incinerated, it produces slag. This slag needs to be crushed. However, once the slag is crushed, it will produce a large amount of dust. If this dust is directly emitted into the air, it will cause air pollution and pose a certain threat to human health. Therefore, dust suppression and dust removal devices are needed when crushing slag.

[0003] Existing dust removal devices for municipal solid waste incinerator slag crushing involve a dust collection cloth inside the dust collection box. This cloth traps dust particles, allowing them to be collected and discharged. Two rotating shafts on one side of the cloth have brushes that clean the dust adhering to it, ensuring the dust is discharged directly through the outlet and preventing clogging. The gas after dust removal is then decomposed and sterilized by UV lamps, followed by deodorization by activated carbon adsorption plates. Finally, the gas is purified by moisture removal before being released directly into the air, reducing air pollution. However, these devices occupy a large area, making them unsuitable for small areas. Furthermore, the direct filtration of exhaust gas and residue, often accompanied by high-temperature exhaust gas, can damage the filter layer and shorten the equipment's lifespan. Utility Model Content

[0004] To address the aforementioned issues of large footprint and high heat from exhaust gases damaging activated carbon mesh, this invention provides a cooling and deodorizing device for municipal solid waste incinerator slag.

[0005] This utility model provides a cooling and deodorizing device for municipal solid waste incineration slag, which adopts the following technical solution:

[0006] A municipal solid waste incinerator slag cooling and deodorization device includes a main body, a top cover connected to the top of the main body, an air inlet connected to the center of the top cover, a connecting block connected to the bottom of the top cover, a receiving block connected to the bottom of the connecting block, an auxiliary block connected to the center of the receiving block, a filter screen connected to the inner side of the auxiliary block, and a slag outlet opened on one side of the filter screen.

[0007] A baffle is provided below the connecting block, and transmission pipes are connected to both sides of the baffle. An air extraction mechanism is provided below the baffle, and an activated carbon mesh is provided in the center of the air extraction mechanism. A one-way air valve is provided above the activated carbon mesh, and an air outlet is provided above the one-way air valve.

[0008] The above technical solution facilitates the filtration of impurities by using connecting blocks and receiving blocks, and after use, the exhaust gas is cooled by using a transmission pipe and a cold water tank to prevent it from affecting the activated carbon mesh.

[0009] Optionally, in the above-mentioned municipal solid waste incinerator slag cooling and deodorization device, the main body of the device and the top cover of the device are detachable structures, the center of the top cover of the device coincides with the center of the air inlet, and the inner side of the air inlet is provided with a threaded groove.

[0010] The above technical solution facilitates the quick removal of residue using a detachable top cover, making cleaning easier.

[0011] Optionally, in the above-mentioned municipal solid waste incinerator slag cooling and deodorization device, the connecting block and the top cover of the device are installed as an integral part, and the receiving blocks are symmetrically distributed on both sides of the center of the connecting block. The connection between the receiving block and the auxiliary block is a sliding connection.

[0012] The above technical solution facilitates dual filtration through dual receiving blocks, thereby improving the filtration effect.

[0013] Optionally, in the above-mentioned municipal solid waste incineration slag cooling and deodorization device, the baffle is connected to the main body of the device by heat fusion connection, and transmission pipes are symmetrically distributed on both sides of the baffle. The transmission pipes have a spiral structure and are located inside the cold water tank.

[0014] The above technical solution facilitates the use of baffles in conjunction with transmission pipes to cool exhaust gas and prevent it from affecting subsequent filtration.

[0015] Optionally, in the above-mentioned municipal solid waste incinerator slag cooling and deodorization device, the top of the air extraction mechanism is integrated with the transmission pipe, the air outlet pipes of the air extraction mechanism are symmetrically distributed on both sides of the center of the activated carbon mesh, and the outer side of the activated carbon mesh is connected to a partition.

[0016] The above technical solution facilitates the extraction of exhaust gas from the top to the bottom via the extraction mechanism, preventing exhaust gas from accumulating at the top.

[0017] Optionally, in the above-mentioned municipal solid waste incinerator slag cooling and deodorization device, a gas supply pipe is also connected above the activated carbon mesh, and the gas supply pipe and the one-way gas valve are installed as an integral part, with the center of the one-way gas valve coinciding with the center of the baffle.

[0018] The above technical solution facilitates the placement of waste gas into water flow through the combination of activated carbon mesh and one-way valve, thereby achieving further dust removal.

[0019] In summary, this utility model has at least one of the following beneficial effects:

[0020] By setting connecting blocks and receiving blocks inside the main body of the device, the residue can pass through multiple filter screens in sequence after entering the main body of the device, and then accumulate inside the receiving block along the slag outlet. The exhaust gas is cooled by cold water through a spiral transmission pipe before entering the subsequent steps, thus avoiding the exhaust gas from affecting the activated carbon screen.

[0021] By installing an air extraction mechanism and activated carbon mesh at the bottom of the transmission pipe, the exhaust gas can flow downwards and be filtered by the activated carbon mesh to remove impurities. Finally, the exhaust gas enters the interior of the cold water tank for secondary filtration and is discharged through the air outlet. The structure is simple and occupies a small area.

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1-4 This utility model provides an embodiment of a municipal solid waste incinerator slag cooling and deodorization device, comprising a device body 1, a device top cover 2 connected to the top of the device body 1, an air inlet 3 connected to the center of the device top cover 2, through which waste gas and residue are placed into the interior of the device body 1, a connecting block 4 connected to the bottom of the device top cover 2, a receiving block 5 connected to the bottom of the connecting block 4, an auxiliary block 12 connected to the center of the receiving block 5, through which the receiving block 5 and the auxiliary block 12 cooperate to separate the residue and waste gas, a filter screen 13 connected to the inner side of the auxiliary block 12, and a slag outlet 14 opened on one side of the filter screen 13, through which the residue is discharged into the interior of the receiving block 5 to avoid affecting the flow of waste gas;

[0029] Below the connecting block 4, there is a baffle 6. The two sides of the baffle 6 are connected to the transmission pipes 7. Below the baffle 6, there is a suction mechanism 8. The suction mechanism 8 works with the transmission pipes 7 to draw the exhaust gas to the bottom. An activated carbon mesh 9 is set in the center of the suction mechanism 8. A one-way valve 10 is set above the activated carbon mesh 9. The exhaust gas is discharged through the one-way valve 10 to prevent water flow. An air outlet 11 is set above the one-way valve 10.

[0030] Working principle: When in use, firstly, the residue and exhaust gas are placed into the inside of the connecting block 4 through the air inlet 3. Then, the exhaust gas and residue fall into the inside of the receiving block 5. After being filtered by the filter screen 13, the exhaust gas continues to flow downwards, and the residue falls into the inside of the receiving block 5 along the filter screen 13 and the slag outlet 14. After long-term use, open the top cover 2 of the device, pull out the auxiliary block 12, and clean the residue.

[0031] As described above, after the exhaust gas enters above the baffle 6, the switch of the exhaust mechanism 8 is turned on, allowing the exhaust gas to flow through the transmission pipe 7. During the flow, the cold water between the baffles 6 cools the exhaust gas. Then, the exhaust gas undergoes secondary filtration through the activated carbon mesh 9, and finally is discharged into the interior of the cold water tank through the one-way valve 10. After the final filtration is completed, it is discharged through the outlet 11.

[0032] It should be noted that the main body 1 and the top cover 2 are detachable. The center of the top cover 2 coincides with the center of the air inlet 3. The inner side of the air inlet 3 is provided with a threaded groove. The detachable top cover 2 can be used to quickly remove residues for easy cleaning.

[0033] It should be noted that the connecting block 4 is installed as an integral part of the device top cover 2. The receiving blocks 5 are symmetrically distributed on both sides of the center of the connecting block 4. The connection between the receiving block 5 and the auxiliary block 12 is a sliding connection. The double receiving blocks 5 are used for double filtration to improve the filtration effect.

[0034] It should be noted that the connection between the baffle 6 and the main body 1 of the device is a heat fusion connection. The transmission pipes 7 are symmetrically distributed on both sides of the baffle 6. The transmission pipes 7 have a spiral structure and are located inside the cold water tank. The baffle 6 and the transmission pipes 7 work together to cool the exhaust gas and prevent it from affecting the subsequent filtration. The cold water tank is provided with inlet and outlet water pipes on both sides, but these are not shown in the existing technical drawings.

[0035] It should be noted that the top of the extraction mechanism 8 is integrated with the transmission pipe 7. The exhaust pipes of the extraction mechanism 8 are symmetrically distributed on both sides of the center of the activated carbon mesh 9. The outer side of the activated carbon mesh 9 is connected to a partition. The exhaust mechanism 8 draws the exhaust gas from the top to the bottom, preventing the exhaust gas from accumulating at the top.

[0036] It should be noted that an air supply pipe is also connected above the activated carbon mesh 9, and the air supply pipe is integrated with the one-way valve 10. The center of the one-way valve 10 coincides with the center of the baffle 6. Through the cooperation of the activated carbon mesh 9 and the one-way valve 10, the waste gas is placed into the water flow, thereby achieving further dust removal.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
