Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking and pollution-cleaning, in particular to a water film anti-blocking and pollution-cleaning dust remover. Background Art

[0002] The appearance of the water film dust collector is a circular cylinder. Water enters the cylinder from the spray pipe in the upper part of the dust collector, forming a layer of water film on the entire inner wall of the cylinder and flowing from top to bottom. The flue gas enters tangentially from the lower part of the cylinder and rotates and rises in the cylinder. The dust-containing gas always rubs against the water film on the inner wall of the cylinder under the action of centrifugal force. In this way, the dust-containing gas is moistened by the water film, and the dust particles flow to the bottom of the dust collector with the water.

[0003] The existing device may encounter the following situations during use:

[0004] 1. The existing water film dust collector can only absorb and remove dust in the air through the water film, and the water after adsorbing the dust needs other devices to filter and separate again. Moreover, with a long period of separation, the dust in the water will clog the filter device and affect the filtering effect.

[0005] 2. Add a filtering device to the water film dust collector. Since the device is always in working condition, dust will accumulate and settle in the filtering device after working for a long time. The dust removal filtering device needs to be replaced in time to ensure the normal operation of the device, and it is impossible to shut down for replacement, which is time-consuming and labor-intensive.

[0028] When the utility model is used:

[0029] First, other substances are added between the second partition plate 7 and the dust removal tank body 1 through the exhaust port 106 to absorb harmful substances in the air. After the pipeline is connected, the valve 103 is opened to inject water into the water storage chamber 8. The position of the water in the water storage chamber 8 is always located at the lower end of the second partition plate 7. After the water injection is completed, the valve 103 is closed, and the circulating water pump 104 is started to work, so that the water in the water storage chamber 8 circulates;

[0030] Then, the water in the water storage chamber 8 passes through the gap between the first baffle plate 6 and the dust removal tank body 1 and falls along the inner wall of the dust removal tank body 1, and drips through the one-way drain valve 602, starting the motor 105 to work, and at the same time, the dust-containing air is blown into the interior of the dust removal tank body 1 and blown toward the fan blade 4 through the air inlet 108. The fan blade 4 rotates after being affected by the wind and generates wind force by itself, so that the dust-containing air is blown toward the inner wall of the dust removal tank body 1, so that the dust-containing air is tightly attached to the inner wall of the dust removal tank body 1, and then the dust-containing air is in contact with the water flow on the inner wall of the dust removal tank body 1, and the water adsorbs the dust in the air. The adsorbed air enters the water storage chamber 8 through the one-way vent 603 and is adsorbed by the water again. The air will enter the liquid at the upper end of the second baffle plate 7 through the one-way vent valve 701 to remove other harmful substances in the air. After completion, the clean air is discharged from the exhaust port 106;

[0031] Next, the water that absorbs the dust falls into the filter plate 2 for filtration, and the filtered water falls and returns to the water storage chamber 8 through the circulating water pump 104 and the circulating pipe 101, forming a water cycle, effectively saving water resources, and the filtered dust accumulates and settles on the surface of the filter plate 2, and the motor 105 rotates, and drives the motor 105, the rotating rod 1051, the spiral blade 1052 and the anti-blocking scraper 9 to rotate. The anti-blocking scraper 9 is in close contact with the inner wall of the filter plate 2 to scrape off the dust settled on the surface of the filter plate 2 to prevent the dust from clogging the filter plate 2. The scraped dust falls to the center along the filter plate 2 and is lifted by the spiral blade 1052. When the dust is first lifted, it will carry water. The water in the lifting process will be discharged through the drain port 501, so that the spiral blade 1052 only lifts the settled dust, and the dust is discharged through the dust exhaust pipe 107 after being lifted.

[0032] Finally, a pipe is connected to the dust exhaust pipe 107 or a dust collecting box is provided to centrally process the deposited dust.
