Technical Field

[0001] The utility model relates to the technical field of waste gas dust removal, in particular to a waste gas dust removal, purification and filtration structure. Background Technique

[0002] The boiler burns fuel in the combustion chamber to generate high-temperature flue gas. Through the smoke pipes or water pipes, the water is heated to generate steam or hot water. The steam is transported to industrial equipment for heating or doing work, and the hot water is circulated for heating through a circulating pump. When the boiler is working, it will inevitably generate waste gas, which generally contains a large amount of dust and harmful gases. The dust and harmful gases in the waste gas need to be filtered before being discharged.

[0003] Patent Application No.: 202320056111.9 proposes a waste gas dust removal, purification and filtration structure, including a box body and an air inlet. A dust removal device is arranged inside the box body. The dust removal device includes a dust removal box and atomizing nozzles. One end of the water outlet pipe is fixedly connected to the inner surface of the dust removal box. Multiple groups of atomizing nozzles are fixedly connected to the surface of the water outlet pipe. The water outlet pipe penetrates through the surfaces of the dust removal box and the water tank and is fixedly connected to a water pump. The water pump is fixedly connected to the inner surface of the water tank. In this waste gas dust removal, purification and filtration structure, through the cooperation of the mesh changing device and the dust removal device, the water inside the water tank is sprayed into the dust removal box through the water outlet pipe and the atomizing nozzles, so that the particulate matter in the waste gas is covered by the water mist and falls onto the surface of the collection box, and the filter screen slides out from the outlet opening. Through multiple groups of filtering structures, the harmful substances in the waste gas are collected and purified, so that the harmful substances in the processed waste gas are greatly reduced, and it will have a certain guarantee for the environment after being discharged.

[0021] Please refer to Figures 1-4, an exhaust gas dust removal and purification filtration structure, including a box body 1. Inside the box body 1, a partition 2 is fixedly installed. The partition 2 divides the interior of the box body 1 into a dust removal chamber 3 and a drying chamber 4. On the upper surface of the box body 1, an air suction pipe 11 is fixedly installed. Both ends of the air suction pipe 11 are communicated with the dust removal chamber 3 and the drying chamber 4 respectively. On the bottom surface of the box body 1, a motor 8 is fixedly installed. The output end of the motor 8 is fixedly installed with a connecting shaft 13. The connecting shaft 13 extends into the interior of the dust removal chamber 3. On the outer surface of the connecting shaft 13, two groups of stirring paddles 9 are fixedly installed. The top end of the connecting shaft 13 fixedly extends into the interior of the air suction pipe 11. At the top end of the connecting shaft 13, a fan 12 is fixedly installed. On the side surface of the box body 1, an air inlet pipe 5 is fixedly installed. One end of the air inlet pipe 5 extends into the interior of the dust removal chamber 3.

[0022] When the exhaust gas enters the dust removal chamber 3 through the air inlet pipe 5, the stirring paddles 9 rotate driven by the motor 8, so that the exhaust gas is fully mixed with the mixed liquid in the dust removal chamber 3, facilitating the removal of dust and harmful substances soluble in water in the exhaust gas. The filtered exhaust gas is preliminarily filtered through a filter screen 15, and dust can be further removed. When the connecting shaft 13 drives the stirring paddles 9 to rotate, it will also drive the fan 12 to rotate. The fan 12 rotates in the air suction pipe 11, facilitating the discharge of the filtered gas into the interior of the drying chamber 4 through the air suction pipe 11.

[0023] On the upper surface of the box body 1, a water pump 17 is fixedly installed. Inside the dust removal chamber 3, a filter screen 15 is fixedly installed.

[0025] On the upper right side surface of the box body 1, an air outlet pipe 22 is fixedly installed. The air outlet pipe 22 is communicated with the drying chamber 4. Inside the drying chamber 4, two drying and filtering plates 19 are installed. The drying and filtering plates 19 are all arranged on the right side of the air suction pipe 11. The drying and filtering plates 19 further dry the exhaust gas to remove moisture and humidity in it. The treated clean gas is discharged into the atmosphere through the air outlet pipe 22.

[0026] One end of the intake pipe 5 is fixedly installed with an annular pipe 6. The annular pipe 6 is arranged between two stirring paddles 9. The bottom surface of the annular pipe 6 is fixedly installed with a plurality of outlets, which is convenient for the waste gas to be dispersed into the liquid inside the dust removal chamber 3, improving the contact area between the waste gas and the liquid, and enhancing the reaction rate between the liquid and the harmful substances in the waste gas. An expansion ball 7 is fixedly installed on the intake pipe 5. The water level height of the dust removal chamber 3 is between the collision ball 7 and the upper stirring paddle 9. The expansion ball 7 is used to prevent negative pressure from being generated inside the intake pipe 5 and suck back the liquid inside the dust removal chamber 3.

[0027] Furthermore, an observation window 23 is fixedly installed on the front surface of the box body 1. The observation window 23 corresponds to the position of the dust removal chamber 3 and is used to observe the liquid level of the liquid inside the dust removal chamber 3, facilitating timely water replenishment.

[0028] One end of the water inlet of the water pump 17 is fixedly installed with a water replenishing pipe 16.

By starting the water pump 17, water is added into the dust removal chamber 3. The water level height of the dust removal chamber 3 is between the collision ball 7 and the upper stirring paddle 9. Then, according to the type of waste gas to be treated, a reagent is added into the dust removal chamber 3 through the reagent pipe 24 to react with the harmful substances in the waste gas. The pH meter 14 monitors the acidity and alkalinity of the liquid in the dust removal chamber 3 in real time, facilitating the timely replenishment of the reagent.

[0032] When the waste gas enters the dust removal chamber 3 through the intake pipe 5, the stirring paddle 9 rotates driven by the motor 8, so that the waste gas is fully mixed with the mixed liquid in the dust removal chamber 3, facilitating the removal of dust and harmful substances soluble in water in the waste gas. The filtered waste gas is preliminarily filtered through the filter screen 15, and dust can be further removed. When the connecting shaft 13 drives the stirring paddle 9 to rotate, it will also drive the fan 12 to rotate. The fan 12 rotates in the suction pipe 11, facilitating the discharge of the filtered gas into the interior of the drying chamber 4 through the suction pipe 11. The drying filter plate 19 further dries the waste gas to remove moisture and humidity therein. The treated clean gas is discharged into the atmosphere through the outlet pipe 22;

[0033] After the device works for a period of time, the waste liquid and solid impurities inside the dust removal chamber can be discharged through the waste liquid pipe 10. By starting the water pump 17, water is pumped into the second annular pipe 18 and then sprayed out through the nozzles on the second annular pipe 18, facilitating the addition of water into the interior of the dust removal chamber 3. At the same time, the surface of the filter screen 15 can also be rinsed. When the drying filter plate 19 needs to be maintained or replaced, just loosen the bolts and pull out the support frame 20 from the installation slot.
