[0017] like Figure 1 A bisphenol A dust recovery and utilization device includes a bisphenol A dust collector 6, which is connected to a feed pipe and a dust removal fan 5, the lower end discharge port of the bisphenol A dust collector 6 is connected to a dust collection tank 9 through a first discharge pipe, and the discharge port of the dust collection tank 9 is connected to a bisphenol A silo 4 through a second discharge pipe, and a nitrogen recovery dust collector 3 is installed on the bisphenol A silo 4, and the nitrogen recovery dust collector 3 is connected to the dust collection tank through a circulating air pipe, and a compressor 1 is installed on the circulating air pipe. It also includes a nitrogen gas cabinet 2, which is connected to the nitrogen recovery dust collector 3. A shut-off valve 8 is installed on the first discharge pipe. A material level meter 7 is provided on the bisphenol A dust collector 6. A compressed nitrogen valve 10 is installed on the circulating air pipe.

[0018] The working process of the utility model is as follows: bisphenol A dust is fed into the bisphenol A dust collector 6 through the feed pipe for recovery. After the material level meter 7 detects that the bisphenol A dust collector 6 has accumulated to a certain material level, the shut-off valve 8 is opened, and the dust in the bisphenol A dust collector 6 falls into the dust collecting tank 9. After the dust discharge is completed, the shut-off valve 8 is closed, the nitrogen compressor 1 is started, and the compressed nitrogen valve 10 is opened to fluidize the dust in the dust collecting tank 9 and send it to the bisphenol A silo 4 for production use. The nitrogen returns to the nitrogen gas cabinet 2 through the bisphenol A silo 4 and the nitrogen recovery dust collector 3, and the nitrogen gas cabinet 2 is recycled through the nitrogen compressor 1.

[0019] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
