Description

Technical Field

[0001] The utility model relates to the technical field of smoke filtering, in particular to a novel smoke filtering device. Background Art

[0002] Flue gas is a mixture of gas and smoke. The emission of flue gas is one of the causes of air pollution. Smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products. The harmfulness of smoke to humans is related to the size of the particles. Most of the harm to humans is caused by floating dust with a diameter of less than 10 microns, among which floating dust of 1 to 2.5 microns is the most harmful. Flue gas filtration equipment refers to the equipment used to filter the harmful smoke and industrial waste gas generated during production operations.

[0003] The existing new flue gas filtration equipment mainly focuses on how to strengthen the filtration of the filter element. The existing flue gas filtration equipment usually uses a filter mesh for primary filtration, and then uses a filter element to adsorb small particles, and finally discharges clean air into the atmosphere. However, due to large particles of flue gas dust, the filter mesh is not completely filtered, and large dust particles enter the filter element. Although the filter element filters out the dust, the large particles of dust entering will cause the filter element to need to be replaced frequently, affecting the service life of the filter element. In addition, the filter element cost is high, and replacing the filter element is time-consuming. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a new type of flue gas filtering equipment, which has the advantages of reducing the entry of large particles of dust into the filter element, increasing the service life of the filter element, and saving the operating cost of the flue gas filtering equipment. It solves the problem that due to large particles of flue gas dust, the filter net is not completely filtered out, and large dust particles enter the filter element. Although the filter element filters out the dust, the large particles of dust entering will cause the filter element to need to be replaced frequently, affecting the service life of the filter element, and the filter element cost is high, and the replacement of the filter element is time-consuming.

[0005] In order to achieve the above-mentioned purpose of reducing the large dust particles from entering the filter element, increasing the service life of the filter element, and saving the operating cost of the smoke filtering device, the utility model provides the following technical solutions: a novel smoke filtering device, comprising a box body, a smoke inlet interface is arranged on the top of the box body, an air outlet interface is arranged on the outside of the box body, a controller is arranged on the outside of the box body, and a purification structure is arranged inside the box body;

[0006] The purification structure includes a smoke inlet pipe, a filter box cover, a filter box, an activated carbon filter, an air inlet pipe, a water storage tank, a water transport pipe, a diversion pipe, a nozzle, a water pump, an air outlet pipe, a graphene coated filter element and an exhaust fan. A smoke inlet pipe is arranged inside the box body, a filter box cover is hinged on the top of the box body, a filter box is arranged inside the box body, three activated carbon filters are arranged inside the filter box, an air inlet pipe is fixedly installed on the right side of the filter box, a water storage tank is arranged inside the box body, a water transport pipe is fixedly installed on the top of the box body, a diversion pipe is fixedly installed on the inner top wall of the water storage tank, three nozzles are arranged at the bottom of the diversion pipe, a water pump is fixedly installed at the bottom of the water transport pipe, an air outlet pipe is arranged outside the water storage tank, a graphene coated filter element is fixedly installed outside the air outlet pipe, and an exhaust fan is arranged on the left side of the graphene coated filter element.

[0007] Furthermore, the left side of the filter box is connected to the smoke inlet interface through the smoke inlet pipe, and the right side of the filter box is connected to the water storage tank through the air inlet pipe.

[0008] Furthermore, a protection box adapted to the water pump is arranged outside the box body.

[0009] Furthermore, a water filling interface adapted to the water storage tank is provided on the top of the box body.

[0010] Furthermore, the graphene coated filter element is connected to the water storage tank through an air outlet pipe.

[0011] Furthermore, the controller is electrically connected to the water pump and the exhaust fan through wires.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The novel flue gas filtering equipment is provided with a purification structure. When the flue gas needs to be filtered, the controller is turned on, the exhaust fan and the water pump are turned on by the controller, and the flue gas to be input is connected to the smoke inlet interface. The flue gas enters the filter box through the smoke inlet pipe and passes through the three-layer activated carbon filter to remove a part of the large particles of dust in the flue gas, and then enters the water storage tank through the air inlet pipe. The nozzle sprays water mist to remove the unfiltered large particles of dust. Finally, the flue gas reaches the graphene coated filter element through the air outlet pipe, purifies and filters out most of the small particles of dust, and is discharged from the air outlet interface after meeting the emission standards. The purification structure can reduce the large particles of dust entering the filter element, increase the service life of the filter element, and thus save the operating cost of the flue gas filtering equipment.

[0021] In the case implementation, a filter box cover 502 is hinged on the top of the box body 1, a filter box 503 is arranged inside the box body 1, and three activated carbon filters 504 are arranged inside the filter box 503. After being used for a long time, the filter box cover 502 can be opened, the three activated carbon filters 504 can be replaced, and then the large dust particles remaining at the bottom of the filter box 503 can be cleaned, which is beneficial to improve the effect of smoke filtration.

[0022] In the case implementation, an air intake pipe 505 is fixedly installed on the right side of the filter box 503, a water storage tank 506 is arranged inside the box body 1, a water transport pipe 507 is fixedly installed on the top of the box body 1, a diversion pipe 508 is fixedly installed on the inner top wall of the water storage tank 506, three nozzles 509 are arranged at the bottom of the diversion pipe 508, and a water pump 5010 is fixedly installed at the bottom of the water transport pipe 507.

[0024] 1) First, when the smoke needs to be filtered, the controller 4 is turned on, and the exhaust fan 5013 and the water pump 5010 are turned on through the controller 4;

[0025] 2) Then the smoke to be input is connected to the smoke inlet interface 2, and the smoke enters the filter box 503 through the smoke inlet pipe 501 and passes through the three-layer activated carbon filter 504 to remove part of the large particles of dust in the smoke;
