DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model discloses a fly ash treatment device suitable for a waste incineration power plant, comprising a treatment device shell 1, a baffle 9 is arranged on one side of the treatment device shell 1, a fixing frame 8 is fixedly mounted on the baffle 9, a first filter screen 7 is arranged inside the fixing frame 8, a slide rail 6 is arranged outside the fixing frame 8, and the slide rail 6 is fixedly mounted on the inner wall of the treatment device shell 1, a limit block 12 is fixedly mounted on the surface of one side of the baffle 9, a rotatable clamping block 13 is installed on one side of the treatment device shell 1, a rotary switch 14 is fixedly mounted on one side of the clamping block 13, a sealing groove 11 is arranged at the connection between the baffle 9 and the treatment device shell 1, and a handle 10 is fixedly mounted on the surface of the baffle 9 for easy pulling out of the fixing frame 8.

[0024] The flue gas containing fly ash enters the treatment device housing 1 from the smoke inlet 2, and some of the fly ash is cleaned off by water sprinkled from the spray head 21, and then small particles of fly ash are filtered out through the first filter 7, and finally discharged through the smoke outlet 3. During this process, fly ash will remain on the surface of the first filter 7, so it is necessary to clean and replace the first filter 7 in time. When the filter needs to be cleaned, it is only necessary to turn the two sets of rotary switches 14 on the surface of the baffle 9, and then pull the handle 10 to pull out the fixing frame 8, so as to disassemble the first filter 7, which is convenient for cleaning and maintenance of the first filter 7, thereby maintaining a good filtering effect and helping to extend the service life of the filter. Regularly cleaning the fly ash on its surface can ensure that the filter maintains the best filtering effect.

[0025] See also Figure 1 and Figure 5A square funnel 15 is fixedly connected to the bottom of the treatment device shell 1, a second filter screen 16 is fixedly installed on the bottom of the square funnel 15, a water outlet 17 is arranged below the second filter screen 16, an adapter 18 is fixedly connected below the water outlet 17, a water collecting tank 20 is fixedly connected to one side of the adapter 18, and the water outlet 17, the adapter 18 and the water collecting tank 20 are fixedly connected by a pipe 19.

[0026] The water sprayed by the sprinkler head 21 carries the fly ash down and enters the square funnel 15. The second filter screen 16 below the square funnel 15 can filter the water therein, and the water flows into the pipe 19 through the outlet 17, and then is concentrated in the water collecting tank 20. It can be sent to the water injection port 5 by a water pump for recycling, which saves water resources, avoids subsequent more complicated treatment processes, and reduces treatment costs.

[0027] See also Figure 4 A sealing layer 22 is fixedly installed on the sealing groove 11, which can ensure good sealing of the device and prevent smoke leakage from polluting the environment.

[0028] See also Figure 1 and Figure 6 A water collecting plate 4 is fixedly connected to the top of the treatment device shell 1, a water injection port 5 is fixedly connected to the top of the water collecting plate 4, a plurality of sprinkler heads 21 are evenly installed at the bottom of the water collecting plate 4, and a slide rail 6 is fixedly installed, so that part of the fly ash carries water, increases its mass, falls under the action of gravity, and enters the square funnel 15, which can remove part of the fly ash and increase the treatment effect of the fly ash.

[0029] See also Figure 1 A smoke inlet 2 is fixedly connected to one side of the treatment device housing 1, and a smoke outlet 3 is fixedly connected to the other side, so that smoke containing fly ash can enter the device and be discharged outside the device.

[0030] Working principle: When the filter needs to be cleaned, you only need to turn the two sets of rotary switches 14 on the surface of the baffle 9, and then pull the handle 10 to pull out the fixing frame 8 to disassemble the first filter 7, which is convenient for cleaning and maintenance of the first filter 7, thereby maintaining a good filtering effect and helping to extend the service life of the filter. Regularly cleaning the fly ash on its surface can ensure that the filter maintains the best filtering effect. The sprayed water is filtered by the second filter 16 and then concentrated in the water collecting tank 20. It can be pumped into the water inlet 5 for recycling, saving water resources, and avoiding subsequent more complicated processing processes, reducing processing costs.
