[0027] Refer to Figures 1 - 5 , the present utility model provides the following two technical solutions:

[0032] A connecting frame 2 is fixedly connected to the outer wall of the oligoether processing tank 3, and an installation frame 1 is fixedly connected to the outer wall of the connecting frame 2.

[0033] A feed pipe 6 is fixedly connected to the top end of the inorganic membrane filter element connection mechanism 7.

[0034] A discharge pipe 4 is fixedly connected to the bottom end of the oligoether processing tank 3, and a guiding pipe 5 is fixedly connected to the bottom end of the oligoether processing tank 3.

[0035] The inorganic membrane filter element connection mechanism 7 includes an adjustment box 71. The adjustment box 71 is fixedly connected to the top end of the secondary filtration component 8. A feed slot 72 is opened at the top end of the adjustment box 71. A sealing door 73 is hinged to the outer wall of the adjustment box 71. A hinge hole 74 is opened on the outer wall of the sealing door 73. A connection component 75 is arranged on the inner wall of the adjustment box 71. The adjustment box 71 is connected to an oligoether inorganic membrane filter element body 76 through the connection component 75.

[0036] The connection component 75 includes a connection box 751. The connection box 751 is slidably connected to the inner wall of the adjustment box 71. A connection groove 752 is opened on the outer wall of the connection box 751. A sliding groove 753 is opened on the inner wall of the connection groove 752. A movable rod 754 is slidably connected to the inner wall of the sliding groove 753. One end of the movable rod 754 is fixedly connected to a push plate 755. A groove 756 is opened on the outer wall of the push plate 755. A sealing plate 757 is slidably connected to the inner wall of the connection box 751. A sealing groove is opened on the outer wall of the connection box 751.

[0037] The oligoether inorganic membrane filtration device for removing heteropolyacid is provided with an inorganic membrane filter element connection mechanism 7. Through the inorganic membrane filter element connection mechanism 7, it is convenient for operators to quickly remove and install new filter elements, which can greatly shorten the maintenance time and improve the online operation efficiency of the equipment. At the same time, the ability to quickly replace the filter element means that the equipment can resume normal operation in a short time, which is particularly important for continuous production processes and can minimize the economic losses caused by production interruptions.

[0038] The second implementation mode is mainly different from the first implementation mode in that: the secondary filtration component 8 includes a filtration box 81, the filtration box 81 is arranged at the top of the oligomeric ether processing tank 3, a feed inlet 82 is opened on the outer wall of the filtration box 81, a filter plate 83 is arranged on the inner wall of the filtration box 81, an adsorption layer 84 is arranged on one side of the filter plate 83, a deacidification layer 85 is arranged on the other side of the adsorption layer 84, and a rectangular blanking groove 86 is opened on the outer wall of the filtration box 81.

[0039] The oligomeric ether inorganic membrane filtration device for removing heteropolyacid is provided with a secondary filtration component 8. Secondary filtration can capture those tiny impurities that may penetrate the main filtration membrane, thereby improving the filtration efficiency of the whole system. At the same time, since secondary filtration reduces the burden on the main filtration membrane, the number of times of cleaning and replacing the membrane can be reduced, thus reducing the long-term maintenance cost.

[0040] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0041] When the equipment needs to remove heteropolyacid during use, first pass the solution to be removed of heteropolyacid through the feed pipe 6 and the feed tank 72 and enter the adjustment tank 71. Then, it is filtered once through the inorganic membrane filter element body 76 in the adjustment tank 71. The filtered solution enters the filtration box 81 through the blanking groove opened on the outer wall of the adjustment tank 71 and the feed inlet 82 in the secondary filtration component 8. After the solution enters the interior of the filtration box 81, the flue gas first passes through the filter plate 83 fixedly installed on the inner wall of the filtration box 81 for the first layer of filtration. After passing through the filter plate 83 for the first layer of filtration, it then passes through the adsorption layer 84 arranged on one side of the filter plate 83 for the second layer of adsorption filtration. After the flue gas passes through the adsorption layer 84 for the second layer of filtration, it then passes through the deacidification layer 85 arranged on one side of the adsorption layer 84 for the third layer of filtration. After the flue gas passes through the deacidification layer 85 for the third layer of filtration, it then passes through the filter plate 83 arranged on the other side of the deacidification layer 85 for the fourth layer of filtration. After passing through the fourth layer of filtration, the solution can enter the oligomeric ether processing tank 3 through the rectangular blanking groove 86. When the inorganic membrane filter element body 76 needs to be replaced after long-term use, the sealing door 73 can be opened, and then the connection box 751 can be removed. After the connection box 751 is removed, first push the sealing plate 757. When the sealing plate 757 is pushed to a certain extent, the push plate 755 can be pushed by means of the groove 756. By moving the push plate 755, the movable rod 754 is driven to slide in the chute 753. By sliding the movable rod 754, the inorganic membrane filter element body 76 arranged at its top can be gradually pushed out of the connection groove 752. When it is pushed out to a certain extent, the inorganic membrane filter element body 76 can be taken down for replacement.
