[0012] (III) Beneficial effects

[0013] 1. Connect the air inlet pipe to the exhaust pipe, pull out the sealing plug and inject clean water into the water tank. When the fan is started, the air with microsilicon dust will be drawn into the mixing chamber opened at the top of the water tank. The atomizer will atomize the water inside the water tank, and the water mist will mix with the air drawn in by the fan inside the mixing chamber. The water mist will combine with the microsilicon dust in the air. When the mixed water mist enters the condensation box, the flow rate inside the condensation box will slow down. A large amount of water mist will gather and condense into water droplets and enter the confluence cavity. The water droplets with microsilicon dust will converge after entering the confluence cavity and enter the bottom of the drying chamber from the channel at the side end. The filter cotton sheet will absorb the water mist that has not been completely condensed, and discharge the filtered air from the opening at the side end of the dust collecting box.

[0014] 2. The electric heating plate will heat the water containing microsilica dust entering the drying chamber and distill the mixed liquid. The water vapor generated by the heating will accumulate on the top of the drying chamber. Since the interior of the water tank is a closed space, the atomizer will reduce the pressure inside the water tank when atomizing the water inside the water tank. The water vapor at the top of the drying chamber will enter the water tank under the action of pressure and re-condense into water to enter the circulation. When the water inside the drying chamber is evaporated, microsilica dust will be left inside the drying chamber and can be taken out by pulling the slide plate. The mixture containing microsilica dust can be distilled by the electric heating plate to complete the reuse of water and microsilica dust, thereby achieving the effect of saving resources.

[0021] The embodiment of the present application provides a dust removal device for industrial silicon production, which effectively solves the above-mentioned dust removal device. The dust is filtered through the filter screen. The filter screen will become clogged as the use time increases. When the filter screen is clogged, the dust removal effect will be affected. The air inlet pipe is connected to the exhaust gas exhaust pipe, and the sealing plug is pulled out to inject clean water into the water tank. When the fan is started, the air carrying micro-silicon dust will be drawn into the mixing chamber opened at the top of the water tank. The atomizer will atomize the water inside the water tank. The water mist will mix with the air drawn by the fan inside the mixing chamber. The water mist will combine with the micro-silicon dust in the air. When the mixed water mist enters the condensation box, the flow rate inside the condensation box will slow down. A large amount of water mist will gather and condense into water droplets and enter the confluence chamber. The water droplets carrying micro-silicon dust will converge after entering the confluence chamber and enter the bottom of the drying chamber from the channel at the side. The filter cotton sheet will not be completely condensed. The water mist is adsorbed and the filtered air is discharged from the opening on the side of the dust collecting box. The dust removal of the air is completed by condensing the mixture of microsilicon dust and water mist, thereby avoiding the effect of affecting the dust removal efficiency due to filter blockage. The electric heating plate will heat the water containing microsilicon dust entering the drying bin and distill the mixed liquid. The water vapor generated by the heating accumulates on the top of the drying bin. Since the interior of the water tank is a closed space, the atomizer will reduce the pressure inside the water tank when atomizing the water inside the water tank. The water vapor at the top of the drying bin will enter the water tank under the action of pressure, and will be condensed into water again and enter the circulation. When the water inside the drying bin is evaporated, microsilicon dust gathered together will be left inside the drying bin, which can be taken out by pulling the slide plate. The mixture containing microsilicon dust is distilled by the electric heating plate, thereby completing the reuse of water and microsilicon dust, thereby achieving the effect of saving resources.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the above-mentioned dust removal device, and the dust is filtered by the filter screen. The filter screen will become clogged as the use time increases. When the filter screen is clogged, the dust removal effect will be affected. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a dust removal device for industrial silicon production, including a support plate 1, a water tank 2 is fixedly installed on the top of the support plate 1, a dust collecting box 3 is fixedly installed on the top of the support plate 1, a mixing bin 16 is provided on the top of the water tank 2, a confluence chamber 7 is provided inside the dust collecting box 3, a condensation box 6 is fixedly installed inside the confluence chamber 7, and a drying bin 8 is provided inside the dust collecting box 3.

[0025] A fan 4 is fixedly installed on the top of the water tank 2, an air inlet pipe 13 is fixedly installed on the side end of the fan 4, a filter cotton sheet 11 is fixedly installed on the side end of the condensation box 6, and an electric heating plate 9 is fixedly installed on the bottom end of the drying bin 8.

[0026] Four universal wheels 12 are fixedly mounted on the bottom end of the support plate 1 , an atomizer 5 is fixedly mounted inside the water tank 2 , a sealing plug 14 is mounted on the side end of the water tank 2 , and a slide plate 15 is slidably mounted on the side end of the dust box 3 .

[0027] Working principle:

[0028] The first step is to connect the air inlet pipe 13 to the exhaust pipe, pull out the sealing plug 14 and inject clean water into the water tank 2. When the fan 4 is started, the air containing microsilicon dust will be drawn into the mixing chamber 16 opened at the top of the water tank 2. The atomizer 5 will atomize the water inside the water tank 2. The water mist will be mixed with the air drawn in by the fan 4 inside the mixing chamber 16. The water mist will combine with the microsilicon dust in the air. When the mixed water mist enters the condensation box 6, the flow velocity inside the condensation box 6 will slow down. A large amount of water mist will gather and condense into water droplets and enter the confluence chamber 7. The water droplets containing microsilicon dust will converge after entering the confluence chamber 7 and enter the bottom of the drying chamber 8 from the channel at the side end. The filter cotton sheet 11 will adsorb the water mist that has not been completely condensed and discharge the filtered air from the opening at the side end of the dust collecting box 3. By condensing the mixture of microsilicon dust and water mist, the dust removal of the air is completed, thereby avoiding the effect of affecting the dust removal efficiency due to filter blockage.

[0029] In the second step, the electric heating plate 9 will heat the water containing microsilicon dust entering the drying bin 8 and distill the mixed liquid. The water vapor generated by the heating will accumulate at the top of the drying bin 8. Since the interior of the water tank 2 is a closed space, the atomizer 5 will reduce the pressure inside the water tank 2 when atomizing the water inside the water tank 2. The water vapor at the top of the drying bin 8 will enter the interior of the water tank 2 under the action of pressure, and re-condense into water and enter the circulation. When the water inside the drying bin 8 is evaporated, microsilicon dust will be left inside the drying bin 8. It can be taken out by pulling open the slide plate 15. The mixture containing microsilicon dust is distilled by the electric heating plate 9 to complete the reuse of water and microsilicon dust, thereby achieving the effect of saving resources.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
