Description

Technical Field

[0002] Aqueous hydrogen peroxide, also known as hydrogen peroxide, is an important raw material for the production of peroxides such as peracetic acid and thiourea peroxide, and is widely used in the pharmaceutical, textile printing and dyeing, paper bleaching and other industries. In addition, electronic grade hydrogen peroxide is an essential electronic chemical raw material in the large-scale integrated circuit production process.

[0003] In the existing reverse osmosis device for raw hydrogen peroxide aqueous solution, the raw water injection pipe is generally fixed, so that the injected raw hydrogen peroxide aqueous solution falls on the reverse osmosis membrane at a fixed position, which reduces the effective use area of ​​the reverse osmosis membrane for filtration and purification;

[0004] The existing patent (Announcement No.: CN220443560U) is a reverse osmosis device for hydrogen peroxide. This utility model provides a first stirring group and a second stirring group with stirring plates staggered on the liquid storage tank. Before the hydrogen peroxide raw water solution is pumped away for filtration and purification, the precipitate in the hydrogen peroxide raw water solution stored for a long time can be effectively stirred and mixed, thereby further improving the quality of subsequent filtration and purification.

[0005] In view of the above problems, existing patents provide solutions, but in actual use, the hydrogen peroxide is not precipitated, resulting in a large amount of impurities remaining on the reverse osmosis membrane during reverse osmosis, which reduces the service life of the reverse osmosis membrane and reduces the filtering effect.

[0006] For this reason, a hydrogen peroxide reverse osmosis filter tank is proposed. Utility Model Content

The filter chamber 301 is arranged on one side of the feed pipe 201 , and the filter core 302 is arranged inside the filter chamber 301 and used in conjunction with the feed pipe 201 .

[0033] When in use, hydrogen peroxide is transported into the interior of the filter bin 301 through the feed pipe 201, then enters the interior of the tank body 1 after filtering impurities through the filter element 302, and then passes through the first reverse osmosis membrane 205, the second reverse osmosis membrane 206 and the third reverse osmosis membrane 207 for purification and filtration in sequence. After three layers of reverse osmosis filtration and purification, impurities contained in the hydrogen peroxide can be effectively removed, and finally the hydrogen peroxide is discharged through the discharge valve 204, so that the filtering and purification effect of the hydrogen peroxide is good.

[0037] Specifically, Figure 5 As shown, a filter grid 7 is disposed on the top of the water blocking ring 404 , and the filter grid 7 is obliquely disposed on the top of the water blocking ring 404 .

[0038] When in use, the hydrogen peroxide that needs to be filtered and purified is transported through the liquid inlet pipe 402 and then enters the interior of the screening bin 501. The screening net 502 will filter the large particles contained in the hydrogen peroxide, and then the hydrogen peroxide will enter the interior of the sedimentation tank 401 for sedimentation treatment. When the hydrogen peroxide just enters the sedimentation tank 401 through the liquid inlet pipe 402, it will be broken up by the stabilizing plate 602, which can prevent the impact force of the water flow from muddying the sedimentation tank 401 and improve the stability and sedimentation efficiency of the sedimentation tank 401.

[0042] By adopting the above technical solution, the problem that the existing hydrogen peroxide reverse osmosis filter tank does not perform precipitation treatment on the hydrogen peroxide during actual use, resulting in a large amount of impurities remaining on the reverse osmosis membrane during reverse osmosis, which reduces the service life of the reverse osmosis membrane and reduces the filtering effect is solved.

[0043] Working principle: When the present application is used, the hydrogen peroxide to be filtered and purified is first transported through the liquid inlet pipe 402, and then enters the interior of the screening bin 501. The screening net 502 will filter the large particles contained in the hydrogen peroxide, and then the hydrogen peroxide will enter the interior of the sedimentation tank 401 for sedimentation treatment. When the hydrogen peroxide just enters the sedimentation tank 401 through the liquid inlet pipe 402, it will be broken up by the stabilizing plate 602, which can prevent the impact force of the water flow from muddying the sedimentation tank 401 and improve the stability and sedimentation efficiency of the sedimentation tank 401. When the hydrogen peroxide in the sedimentation tank 401 submerges the water blocking ring 404, The hydrogen peroxide that has not passed through will be filtered again by the filter grid 7 and then enter the interior of the water blocking ring 404. Finally, the hydrogen peroxide in the water blocking ring 404 will be transported to the interior of the filter bin 301 through the feed pipe 201 and then enter the interior of the tank body 1 after filtering impurities through the filter core 302. Then, it will be purified and filtered through the first reverse osmosis membrane 205, the second reverse osmosis membrane 206 and the third reverse osmosis membrane 207 in sequence. After three layers of reverse osmosis filtration and purification, the impurities contained in the hydrogen peroxide can be effectively removed, and finally, the material is discharged through the discharge valve 204, so that the filtering and purification effect of the hydrogen peroxide is good.
