DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 to Figure 4 A desulfurization circulation pump with a catalytic device shown in the figure comprises a base 1, a pump body 2 is fixedly connected to the upper surface of the base 1, an air intake pipe 4 is connected to the air intake end of the pump body 2, a first filter plate 6 and a second filter plate 7 are fixedly connected inside the air intake pipe 4, and the second filter plate 7 is located between the first filter plate 6 and the pump body 2. The first filter plate 6 is used to filter dust particles in the flue gas, and the second filter plate 7 can use but is not limited to a sponge filter plate, which has the effect of drying water; when the flue gas enters the air intake pipe 4, the first filter plate 6 filters the dust particles in the flue gas, and the dust particles adhere to the first filter plate 6 due to suction. A desulfurization chamber is formed between the first filter plate 6 and the second filter plate 7, and desulfurization treatment is performed inside the desulfurization chamber. A rotating shaft 8 is rotatably connected to the first filter plate 6, and a fan blade 9 is fixedly connected to the end of the rotating shaft 8 away from the second filter plate 7, and the fan blade 9 is provided in a plurality of forms, and the plurality of fan blades 9 are evenly distributed. During the flue gas suction process, the airflow drives the rotating shaft 8 to rotate through the fan blade 9.

[0024] Considering that dust particles adhere to the first filter plate 6 due to suction, it is easy to cause blockage if not cleaned for a long time, a collection box 11 is fixedly connected to the rotating shaft 8, and the collection box 11 is located on the side of the first filter plate 6 facing away from the second filter plate 7. A scraper bar 12 is fixedly connected to the collection box 11, and the scraper bar 12 is slidably attached to the first filter plate 6. A square groove 13 is opened on the collection box 11, and the square groove 13 cooperates with the scraper bar 12. The square groove 13 is at the front end of the collection box 11 in the rotation direction, so that impurities can enter the interior of the collection box 11.

[0025] During the smoke extraction process, the airflow drives the shaft 8 to rotate through the fan blades 9, and the shaft 8 drives the collection box 11 to rotate. The scraper strip 12 is pressed against the first filter plate 6 to push and scrape, and the dust particles enter the interior of the collection box 11 through the square grooves 13.

[0026] The utility model is provided with structures such as a collecting box 11, a scraping strip 12, a square groove 13 and a rotating shaft 8. The rotating shaft 8 drives the collecting box 11 to rotate, and the scraping strip 12 is pressed against the first filter plate 6 to push and scrape. The dust particles enter the interior of the collecting box 11 through the square groove 13, thereby achieving automatic cleaning and avoiding blockage.

[0027] In order to prevent the dust particles inside the collection box 11 from being scattered randomly, a square plate 14 is provided inside the collection box 11. The square plate 14 is sealed with the square groove 13, and a spring 15 is fixedly connected between the square plate 14 and the inner wall of the collection box 11. Since the square groove 13 is at the front end of the collection box 11 in the rotation direction, the square plate 14 is also at the front end of the collection box 11 in the rotation direction. Specifically, when the shaft 8 drives the collection box 11 to rotate, the square plate 14 is also at the front end of the collection box 11 in the rotation direction. The spring 15 is squeezed and contracted by the resistance, and the square groove 13 is opened, so that the dust particles can enter the interior of the collection box 11 from the square groove 13. When the shaft 8 stops rotating, the reset elastic force of the spring 15 resets the square plate 14 and closes the square plate 14, so that the dust particles inside the collection box 11 will not be scattered randomly.

[0028] The dust particles in the collection box 11 can be cleaned manually at regular intervals.

[0029] In order to reduce the resistance during the rotation of the collecting box 11 , a circular hole 16 is opened on the wall of the collecting box 11 . There are multiple circular holes 16 . The inner diameter of the circular hole 16 is small, and foreign particles cannot pass through.

[0030] In order to achieve desulfurization of flue gas, the bottom of the air inlet pipe 4 is connected with a recovery box 5, which is distributed corresponding to the desulfurization chamber, and a desulfurizer is injected into the recovery box 5. The top of the desulfurization chamber is fixedly connected with a square box 17, and the bottom of the square box 17 is provided with a liquid outlet 18, and a plurality of liquid outlet holes 18 are provided, and the inner diameter of the liquid outlet hole 18 is relatively small.

[0031] A circulation device 20 is fixedly connected to the outer wall of the air inlet pipe 4. The circulation device 20 includes a micro pump and a filtering mechanism (not shown in the figure). The filtering mechanism includes a filter screen and other structures. The circulation device 20 can achieve the effects of transportation and filtering. The circulation device 20 is a common technology in the prior art and is not described in detail here. A first infusion pipeline 19 is connected between the circulation device 20 and the square box 17, and a second infusion pipeline 21 is connected between the circulation device 20 and the recovery box 5.

[0032] When working, the circulation device 20 is started, and the circulation device 20 sucks the desulfurizer in the recovery box 5 through the second liquid infusion pipe 21, and sprays it out from the liquid outlet 18 to desulfurize and purify the flue gas; and the desulfurizer flows into the recovery box 5 for recycling, and the filtering mechanism in the circulation device 20 can filter the impurities in the desulfurizer.

[0033] The second filter plate 7 can dry the gas after the desulfurization and purification treatment.

[0034] An elastic sheet 10 is fixedly connected to the rotating shaft 8, and the elastic sheet 10 is located inside the desulfurization chamber. During the flue gas suction process, the airflow drives the rotating shaft 8 to rotate through the fan blades 9, and the rotating shaft 8 drives the elastic sheet 10 to rotate, so that the flue gas and the desulfurizer oscillate and fully contact, thereby improving the purification effect.

[0035] The outlet end of the pump body 2 is connected to an outlet pipe 22, on which a three-way catalytic device 3 is fixedly arranged. The desulfurized flue gas enters the three-way catalytic device 6 for secondary purification and is discharged through the outlet pipe 22. The three-way catalytic device 6 includes a shell, a shock absorbing layer, a carrier, a catalyst and other structures, which convert harmful substances in the flue gas into harmless substances. The three-way catalytic device 6 is a common existing technology and will not be described in detail here.
