[0002] Garbage is solid waste generated in human daily life and production. Due to its large discharge volume, complex and diverse composition, and its pollution, resource and social nature, it needs to be harmless, resource-based, reduced and socialized. If it is not properly handled, it will pollute the environment, affect environmental hygiene, waste resources, damage production and living safety, and destroy social harmony. Garbage disposal is to quickly remove the garbage, treat it harmlessly, and finally make reasonable use of it. The widely used garbage disposal methods today are sanitary landfill, high-temperature composting and incineration. The purpose of garbage disposal is harmlessness, resource utilization and reduction.

[0003] In the process of garbage disposal, high-temperature incineration is required, and the gas produced by high-temperature incineration contains substances that are harmful to the atmosphere. After high-temperature incineration, the gas will be purified before being discharged. However, the temperature of the gas produced by high-temperature incineration is relatively high, which causes the existing waste gas purification equipment to affect the filter device for a long time during operation, causing thermal damage to the filter device, thereby reducing the service life of the filter device. In view of this, we provide a waste gas purification equipment for waste incineration to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-5 The utility model provides the following technical solutions: a waste gas purification and treatment equipment for waste incineration, comprising a base 1, a first filter box 2 and a second filter box 3 are arranged on the top of the base 1 from bottom to top, a support frame 4 is connected between the first filter box 2 and the second filter box 3, a connecting pipe 5 is connected between the first filter box 2 and the second filter box 3, the side wall of the first filter box 2 is connected to an air inlet end 6, the top of the second filter box 3 is connected to an air outlet end 7, a water pipe 8 is installed inside the first filter box 2, a support plate 9 is connected to the side wall of the first filter box 2, a water pump 10 is installed on the top of the support plate 9, and a drainage end 11 is connected to the bottom end of the first filter box 2.

[0024] Preferably, the water pipe 8 passes through the first filter box 2 and is connected to the water outlet of the water pump 10 , and a nozzle is installed at the bottom end of the water pipe 8 .

[0025] Preferably, a water pool 12 is connected to the bottom end of the base 1 and located at the bottom end of the drainage end 11 , and a detachable first filter screen 13 is installed inside the water pool 12 .

[0026] Preferably, a solenoid valve 14 is installed on the surface of the connecting pipe 5 , and the connecting pipe 5 passes through the first filter box 2 and the second filter box 3 and extends to the inside.

[0027] In the embodiment, the beneficial effect is that the high-temperature gas is cooled to improve the service life of the equipment. First, the high-temperature gas enters the first filter box 2 from the air inlet end 6, and then the water pump 10 is connected to the pipeline and placed in the water to start pumping. As the water pump 10 works, the water flows along the water outlet end of the water pump 10 into the water pipe 8. Then the water pressure generated by the operation of the water pump 10 causes water to be sprayed out from the nozzle connected to the end of the water pipe 8 to form water mist, thereby cooling the high-temperature gas entering from the air inlet end 6. At the same time, the water mist will absorb floating objects in the gas. Then, it flows from the drainage end 11 at the bottom of the first filter box 2 to the pool 12, and at the same time it will be filtered by the first filter net 13 in the pool 12, so that the mixed water flowing into the pool 12 becomes clean, and then it is reused to reduce the waste of water resources.

[0028] Embodiment 2

[0029] See also Figure 1-5 A second filter screen 15 and a third filter screen 16 are arranged inside the second filter box 3. The second filter screen 15 and the third filter screen 16 are distributed up and down. A fixed block 17 is connected to the inner wall of the second filter box 3. The ends of the second filter screen 15 and the third filter screen 16 located inside the second filter box 3 are overlapped on the top of the fixed block 17.

[0030] Preferably, the second filter screen 15 and the third filter screen 16 are made of metal, and the second filter screen 15 and the third filter screen 16 are connected to the second filter box 3 by plugging.

[0031] In the embodiment, the beneficial effect is that the second filter 15 and the third filter 16 can be easily replaced when they are blocked, so as to avoid affecting the normal use of the equipment. When the second filter 15 and the third filter 16 are blocked after long-term use of the equipment, the second filter 15 and the third filter 16 can be pulled outward from the inside of the second filter box 3, and then the second filter 15 and the third filter 16 can be pulled out from the side wall of the second filter box 3, and then replaced or cleaned and reinserted, so that the ends of the second filter 15 and the third filter 16 extending into the second filter box 3 can be overlapped on the fixing block 17.

[0032] In summary, the specific working principle of the waste gas purification treatment equipment is that, first, the air inlet end 6 is connected to the equipment used for garbage incineration, and garbage incineration belongs to the existing mature technology, and is not drawn in the attached figure description. Then, the high-temperature gas generated by the incineration of garbage enters the first filter box 2 through the air inlet end 6 for cooling, and at the same time, the floating objects in the high-temperature waste gas are treated, and the floating objects are mixed with water and enter the pool 12 from the drainage end 11 for filtration and storage. Then, the solenoid valve 14 is started to open the passage of the connecting pipe 5, and the cooled gas enters the second filter box 3, and then is filtered for the second time by the second filter screen 15 and the third filter screen 16 in the second filter box 3. Finally, the filtered gas is discharged to the outside through the air outlet end 7.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
