Technical Field

[0001] The invention relates to the technical field of fly ash treatment and filtration, and in particular to a filtering device for fly ash treatment. Background Art

[0002] Fly ash refers to tiny ash particles discharged during the combustion of fuel (mainly coal). Its particle size is generally between 1 and 100 μm. It is a hazardous waste and is also called fly ash or smoke ash. If a large amount of fly ash is not controlled or treated, it will cause air pollution and clog rivers when it enters water bodies. Some of the chemicals in it are harmful to organisms and humans, so the smoke ash particles in the fly ash need to be filtered and treated.

[0003] However, the existing fly ash processing filtering equipment directly introduces the gas containing fly ash for filtering, and the effect is not obvious. Moreover, after using it for a period of time, the filter needs to be regularly disassembled, cleaned and replaced. The disassembly and cleaning process takes a lot of time, which greatly reduces the fly ash processing efficiency. Therefore, a fly ash processing filtering equipment is proposed to facilitate the use of cleaning liquid to wrap the fly ash, and then perform double filtration to separate the ash particles from the gas, and the filter is regularly disassembled to further improve the filtering effect. Summary of the invention

[0004] In response to the problems in the prior art, the present invention provides a filtering device for fly ash treatment, which is convenient for using a cleaning liquid to wrap the fly ash and then perform double filtration to separate the ash particles from the gas, and the filter screen is disassembled regularly to further improve the filtering effect.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] In order to use the cleaning liquid to wrap the fly ash, and then perform double filtration to separate the soot particles from the gas, and regularly disassemble the filter screen to further improve the filtration effect, such as Figure 1-4 As shown, a filter device for fly ash treatment according to the present invention comprises a filter tank 1, a flange 7, a filter screen B11 and a stirring blade 19, a smoke pipe 2 is arranged on the top of the filter tank 1, a spray head 3 is arranged on the top of one side of the filter tank 1, an exhaust pipe 6 is arranged on the other side of the filter tank 1, a flange 7 is installed at the bottom of the exhaust pipe 6 on the other side of the filter tank 1 through a reserved opening and bolts, and one end of the flange 7 is connected to a drain valve 10 through a pipeline;

[0023] A filter screen B11 is provided at the bottom of the filter tank 1 corresponding to the smoke pipe 2 , a spiral roller 18 is provided at the bottom of the filter screen B11 , and stirring blades 19 are evenly provided on the periphery of the spiral roller 18 from top to bottom.

[0024] When in use, the smoke pipe 2 introduces the airflow containing the soot into the filter tank 1, while the suction pump 4 sprays the cleaning liquid in the liquid storage tank 5 through the pipeline and the spray head 3, so that the cleaning liquid wraps the soot particles;

[0025] The water droplets wrapped with the ash particles fall on the filter screen B11, and the excess airflow is discharged from the filter tank 1 through the exhaust pipe 6. The waterproof motor A13 drives the brush 14 to clean and filter it. At the same time, the waterproof vibrator 15 drives the filter screen B11 to cooperate with the rebound of the spring 12, so that the filter screen B11 vibrates and the particles and water droplets accumulated on the filter screen B11 fall into the filter tank 1;

[0026] The waterproof motor B17 then drives the spiral roller 18 to rotate, thereby driving the stirring blade 19 to fully mix the cleaning liquid in the filter tank 1 with the gas containing the fly ash. The cleaning liquid wraps the fly ash and falls to the bottom of the filter tank 1 due to the influence of gravity, while the gas floats upward.

[0027] The drain valve 10 is opened to discharge the sewage at the bottom of the filter tank 1, and the filter A9 again filters the fine ash particles in the sewage to separate the sewage and impurities. The bolts are then regularly removed to clean and replace the filter A9 to further improve the filtering effect on fly ash.

[0028] In order to filter the soot particles contained in the fly ash, for example, Figure 1 As shown, the present invention also includes that the water inlet of the sprinkler head 3 is connected to the suction pump 4 through a pipeline, and the bottom water inlet of the suction pump 4 is connected to the liquid storage tank 5 through a pipeline and bolts.

[0029] When in use, the smoke pipe 2 introduces the airflow containing the ash into the filter tank 1, and the cleaning liquid in the liquid storage tank 5 is sprayed through the pipeline and the spray head 3 by the suction pump 4, so that the cleaning liquid wraps the ash particles.

[0030] For example, Figure 1 , Figure 2 As shown, the present invention also includes that a mounting groove 8 is provided on the inner wall of one end of the flange 7, and a filter screen A9 is mounted in the mounting groove 8 by bolts.

[0031] When in use, the drain valve 10 sucks the sewage at the bottom of the filter tank 1 for discharge, while the filter A9 further filters the soot particles in the sewage. The bolts are removed to drive the flange 7, so as to facilitate the regular replacement of the filter B11.

[0032] For example, Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes that the water outlet of the spray head 3 is located on the top side of the filter screen B11, and the air inlet of the exhaust pipe 6 is located on the bottom side of the filter screen B11.

[0033] When in use, the exhaust pipe 6 discharges excess gas out of the filter tank 1 .

[0034] For example, Figure 1 , Figure 3 As shown, the present invention also includes that a waterproof motor A13 is provided at the top center position of the filter screen B11, the periphery of the filter screen B11 is connected to the inner wall of the filter tank 1 through a spring 12, the top driving end of the waterproof motor A13 is connected to a brush 14 through a rotating shaft, the bottom of the brush 14 is in contact with the top of the filter screen B11, and waterproof vibrators 15 are installed on both sides of the bottom of the filter screen B11 by bolts.

[0035] When in use, water droplets containing ash particles fall on the filter B11. The waterproof motor A13 drives the brush 14 to clean and filter it. At the same time, the waterproof vibrator 15 drives the filter B11 to cooperate with the rebound of the spring 12, so that the filter B11 vibrates and the particles and water droplets accumulated on the filter B11 fall into the filter tank 1.

[0036] For example, Figure 1 , Figure 4 As shown, the present invention also includes that the inner wall of the filter tank 1 corresponds to the bottom of the filter screen B11, and a connecting plate 16 is installed by bolts. A waterproof motor B17 is provided at the bottom center of the connecting plate 16. The bottom driving end of the waterproof motor B17 is connected to the spiral roller 18 through a rotating shaft, and the bottom of the spiral roller 18 is connected to the bottom of the filter tank 1 through a rotating shaft.

[0037] When in use, the spiral roller 18 is driven to rotate by the waterproof motor B17, thereby driving the stirring blade 19 to fully mix the cleaning liquid and the gas containing fly ash in the filter tank 1. The cleaning liquid wraps the fly ash and falls to the bottom of the filter tank 1 due to the influence of gravity, while the gas floats upward.

[0038] When the present invention is in use, the smoke pipe 2 introduces the airflow containing the smoke ash into the filter tank 1, while the suction pump 4 sprays the cleaning liquid in the liquid storage tank 5 through the pipeline and the spray head 3, so that the cleaning liquid wraps the smoke ash particles;

[0039] The water droplets wrapped with the ash particles fall on the filter screen B11, and the excess airflow is discharged from the filter tank 1 through the exhaust pipe 6. The waterproof motor A13 drives the brush 14 to clean and filter it. At the same time, the waterproof vibrator 15 drives the filter screen B11 to cooperate with the rebound of the spring 12, so that the filter screen B11 vibrates and the particles and water droplets accumulated on the filter screen B11 fall into the filter tank 1;

[0040] The waterproof motor B17 then drives the spiral roller 18 to rotate, thereby driving the stirring blade 19 to fully mix the cleaning liquid in the filter tank 1 with the gas containing the fly ash. The cleaning liquid wraps the fly ash and falls to the bottom of the filter tank 1 due to the influence of gravity, while the gas floats upward.

[0041] The drain valve 10 is opened to discharge the sewage at the bottom of the filter tank 1, and the filter A9 again filters the fine ash particles in the sewage to separate the sewage and impurities. The bolts are then regularly removed to clean and replace the filter A9 to further improve the filtering effect on fly ash.
