[0032] The working principle of a boiler flue gas filtering device provided by the utility model is as follows:

[0033] Step 1: First, when filtering the boiler flue gas, open the air inlet pipe 8 so that the flue gas can enter the filter box 4 through the air inlet pipe 8, prompting the filter block 5 to filter the flue gas. At this time, open the nozzle 7 so that the nozzle 7 can quickly spray water to the top of the filter block 5, so that the water can flush the smoke particles inside the filter block 5, and then discharge them into the water tank 3, thereby achieving the cleaning and cooling effect of the filter block 5, thereby avoiding the problem of blockage when there is a lot of dust inside the filter block 5, which makes it difficult for the flue gas to flow through the filter block 5, thereby improving the stability of the flue gas filtering device for long-term operation. When filtering the flue gas, start the air pump 10 so that the air pump 10 can flow The flue gas filtered inside the filter box 4 is absorbed through the exhaust pipe 9, thereby increasing the flow speed during flue gas filtration, that is, increasing the filtration speed of the flue gas.

When the filter block 5 is cooled and cleaned, the water pump 131 is started so that the water pump 131 can inject the water flow inside the water tank 3 into the inside of the delivery pipe 6 through the water pipe 132, thereby achieving the water flow reuse effect, thereby improving the water flow saving effect during flue gas filtration;

[0034] Step 2: When conveying water, the filter screen 15 can filter the water entering the water tank 3, so that large particles of dust in the water can be blocked to the top of the filter screen 15, thereby avoiding the problem of pipe blockage caused by large particles of dust entering the water tank 3, thereby improving the smoothness of the water flow. When installing and fixing the filter screen 15, the sealing column 16 is sleeved on the inside of the limiting groove 14, so that the sealing column 16 can close the limiting groove 14, that is, the water tank 3, thereby avoiding the problem of water being discharged to the outside of the water tank 3 through the limiting groove 14 during circulation, thereby improving the sealing of the water tank 3. When moving the filtering device, the support platform 1 is pushed, so that the sliding wheel 172 can drive the support platform 1 to move horizontally through the support block 171, that is, drive the purification box 2 to move horizontally, thereby facilitating the movement and transportation of the filtering device.

[0035] Compared with the related art, the boiler flue gas filtering device provided by the utility model has the following beneficial effects:

[0036] By setting the nozzle 7, when the boiler flue gas is filtered, the air inlet pipe 8 is opened, so that the flue gas can enter the filter box 4 through the air inlet pipe 8, so that the filter block 5 can filter the flue gas. At this time, the nozzle 7 is opened, so that the nozzle 7 can quickly spray water to the top of the filter block 5, so that the water flow can flush the smoke particles inside the filter block 5, and then discharge them into the water tank 3, so as to achieve the cleaning and cooling effect of the filter block 5, and thus avoid the problem of blockage when there is a lot of dust inside the filter block 5, which makes it difficult for the flue gas to flow through the filter block 5, thereby improving the stability of the flue gas filtering device when working for a long time.
