Description

Technical Field

[0001] This utility model relates to the field of dust removal and purification, and more specifically to a dust removal and purification device for municipal solid waste incineration. Background Technology

[0002] Currently, common methods of municipal solid waste disposal mainly include landfill and pyrolysis. Among these, landfill not only occupies a large amount of land resources but also generates waste gas and wastewater that pollute the air and groundwater. Therefore, this simple treatment method is no longer widely used. Compared with landfill, incineration is a better treatment method. After waste is treated by incineration, it is easier to landfill, saves land, and can also eliminate various pathogens and convert toxic and harmful substances into harmless substances. However, incineration produces a large amount of flue gas. In order to avoid flue gas pollution, the flue gas is introduced into water to remove dust from the flue gas. However, existing purification equipment cannot make the flue gas fully contact the water, resulting in low dust purification efficiency. Utility Model Content

[0003] This utility model provides a dust removal and purification device for municipal solid waste incineration, which enables flue gas to fully contact with water, thereby improving the purification efficiency of water on flue gas dust.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A municipal solid waste incineration dust removal and purification device includes a barrel with a bottom plate at the lower end, an inlet pipe connected to the center of the lower end of the bottom plate, a support arm plate fixed to the upper end of the barrel, a central shaft coaxially arranged with the barrel on the support arm plate, and a circular mesh fixed on the central shaft.

[0006] The circular mesh is provided in multiple forms.

[0007] The diameters of the multiple circular meshes increase sequentially from bottom to top.

[0008] The outermost circular mesh slides in close contact with the inner wall of the barrel.

[0009] A power motor is installed on the support arm plate to drive the rotation of the central shaft.

[0010] A water pipe is provided on the side of the barrel. The lower end of the water pipe is connected to the bottom plate and communicates with the barrel. The upper end of the water pipe extends to the upper end of the barrel. A water pump is provided in the middle of the water pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is combined with Figure 1-5 A detailed description of a municipal solid waste incineration dust removal and purification device is provided:

[0023] A municipal solid waste incineration dust removal and purification device includes a barrel 1 with a bottom plate 2 at the lower end, an inlet pipe 3 connected to the center of the lower end of the bottom plate 2, a support arm plate 12 fixed at the upper end of the barrel 1, a central shaft 6 coaxially arranged with the barrel 1 rotating on the support arm plate 12, and a circular mesh 7 fixed on the central shaft 6.

[0024] The bottom plate 2 and the barrel 1 form a water-holding space. When in use, the flue gas is connected to the inlet pipe 3, so that the flue gas enters the water through the inlet pipe 3 at the center of the bottom plate 2, forming a series of "smoke bubbles" that float continuously from bottom to top. At this time, the transmission shaft 6 drives the disc net 7 to rotate in the water, thereby breaking the "smoke bubbles" that float to the disc net 7, so that the flue gas and water can come into full contact, thereby filtering out the smoke dust in the flue gas and leaving the smoke dust in the water.

[0025] Among them, since the disc mesh 7 is a disc-shaped mesh, it can crush the "smoke bubbles" through the mesh holes, so that the "smoke bubbles" are fully broken, and the smoke and water can come into full contact to remove smoke and dust, thus forming purification.

[0026] Further:

[0027] The disc mesh 7 is provided in multiple ways. The arrangement of multiple disc meshes 7 forms a situation where the "smoke bubbles" come into contact with the multiple disc meshes 7 in sequence, which in turn causes the "smoke bubbles" to be broken multiple times, further allowing the flue gas to come into full contact with water, and thus filtering out the smoke dust in the flue gas.

[0028] Further:

[0029] The diameters of the multiple circular meshes 7 increase sequentially from bottom to top.

[0030] Due to the mesh structure of the disc mesh 7, it can not only break up the "smoke bubbles" but also filter the smoke and dust. When the disc mesh 7 rotates, it can axially throw away the impurities stuck on the disc mesh 7, thus ensuring the breaking and filtering effect of the disc mesh 7. The diameter of the multiple disc meshes 7 increases from bottom to top, ensuring that the impurities thrown off by the disc mesh 7 are not blocked by the lower disc mesh 7 and automatically fall into the bottom plate 2 inside the barrel 1.

[0031] Further:

[0032] By making the periphery of the uppermost disc mesh 7 slide in close contact with the inner wall of the barrel 1, "smoke bubbles" are prevented from passing over the disc mesh 7 without being broken, thus affecting the removal of smoke and dust.

[0033] Further:

[0034] A power motor is installed on the support plate 12 to drive the rotation of the central shaft 6.

[0035] Further:

[0036] A water pipe 4 is provided on the side of the barrel 1. The lower end of the water pipe 4 is connected to the bottom plate 2 and communicates with the barrel 1. The upper end of the water pipe 4 extends to the upper end of the barrel 1. A water pump 5 is provided in the middle of the water pipe 4.

[0037] By activating the water pump 5, the water pipe 4 is used to extract sewage at the bottom plate 2, allowing the sewage to flow back into the tank 1 through the water pipe 4, forming a water circulation flow, and further ensuring that the flue gas and water come into full contact.

[0038] Further:

[0039] The upper end of the water pipe 4 is threadedly connected to a threaded pipe 8, and a filter chamber pipe 9 is fixed to the end of the threaded pipe 8 away from the water pipe 4. Multiple filter holes 10 are evenly provided on the side of the filter chamber pipe 9.

[0040] With the filter tube 9 in place, the sewage pumped out of the bottom plate 2 by the water pump 5 flows into the filter tube 9. The filter tube 9 will filter the sewage through multiple filter holes 10, leaving impurities in the filter tube 9, thereby ensuring the cleanliness of the water in the tank 1 and extending the service life of the water in the tank 1.

[0041] Further:

[0042] The filter tube 9 is threaded with a plug 11 at the end away from the water pipe 4;

[0043] When there are many impurities in the filter tube 9, the plug 11 can be unscrewed at the lower end of the filter tube 9 through the thread, so as to pour out the impurities in the filter tube 9 and ensure the filtration effect of the filter tube 9.

[0044] Further:

[0045] By providing filter cotton inside the filter chamber tube 9, the water filtration effect can be further improved.

[0046] Further:

[0047] The lower end of the base plate 2 is fixed with multiple legs to support the device.

[0048] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
