[0032] The filter mechanism 2 includes a mounting block 21, a filter element 22, a cover plate 23 and a removal assembly 3 for quickly removing the filter element 22. The mounting block 21 is fixedly arranged on the membrane deaerator body 1. The water inlet pipe 11 passes through the mounting block 21. A mounting groove 24 is provided on the mounting block 21. The mounting groove 24 is connected to the water inlet pipe 11. The filter element 22 is movably arranged in the mounting groove 24.

[0033] The removal assembly 3 includes a top plate 31, a spring 32, a first screw rod 33 and a connecting rod 34. The top plate 31 is located below the filter element 22, and the top plate 31 is slidingly connected to the mounting groove 24.

The connecting rod 34 is fixedly arranged at the other end of the first screw rod 33, and the connecting rod 34 can slide through the mounting block 21.

[0034] When in use, after the deoxygenated water is filtered by the filter element 22 from the water inlet pipe 11, it enters the membrane deaerator body 1 for deoxygenation, and the deoxygenated water after deoxygenation is discharged from the water outlet pipe 12; when it is necessary to remove the filter element 22, the cover plate 23 is opened, and the connecting rod 34 is rotated to drive the first screw rod 33 to rotate.

When the filter element 22 needs to be installed later, pull down and rotate the connecting rod 34 until the first screw 33 is threadedly engaged with the mounting block 21. The first screw 33 drives the top plate 31 to move down to a suitable position. At this time, the spring 32 is compressed, and the filter element 22 is placed in the mounting groove 24. The cover plate 23 is closed to complete the replacement of the filter element 22. The membrane deaerator sets the filtering mechanism 2 on the outside of the membrane deaerator body 1, and then cooperates with the removal component 3 to quickly and conveniently disassemble and replace the filter element 22, saving time and effort.

[0036] When it is necessary to open the cover 23, the second screw 42 is rotated. Under the thread cooperation of the second screw 42 and the connecting block 41, the second screw 42 is away from the locking groove 25, the locking fixation of the cover 23 and the second screw 42 is released, and the cover 23 can be rotated to open; when it is necessary to close the cover 23, the cover 23 is rotated to close, and the second screw 42 is rotated. Under the thread cooperation of the second screw 42 and the connecting block 41, the second screw 42 is inserted into the locking groove 25, and the second screw 42 can lock and fix the cover 23; the locking assembly 4 allows the cover 23 to remain tightly closed, ensuring the normal use of the filter element 22.

[0037] like Figure 2 and 3As shown, in this embodiment, the membrane deaerator body 1 includes a shell 13, a water distribution pipe 14, a water collecting pipe 15, a baffle 16, a front baffle 17, a rear baffle 18, a purge gas inlet pipe 19, a purge gas outlet pipe 110 and a plurality of degassing membrane assemblies 111, the front baffle 17 and the rear baffle 18 are fixedly arranged in the shell 13, the water distribution pipe 14 passes through the front baffle 17, and the water distribution pipe 14 is connected to the water inlet pipe 11, the water collecting pipe 15 passes through the front baffle 17, and the water collecting pipe 11 5 is connected to the water outlet pipe 12, the partition plate 16 is fixedly arranged between the water distribution pipe 14 and the water collecting pipe 15, a plurality of through holes 112 are opened on the water distribution pipe 14 and the water collecting pipe 15, a purge gas inlet pipe 19 is connected to the rear end of the shell 13, and a purge gas outlet pipe 110 is connected to the front end of the shell 13, and a plurality of degassing membrane assemblies 111 are evenly distributed in the shell 13, and the degassing membrane assemblies 111 penetrate the front baffle plate 17, the partition plate 16, and the rear baffle plate 18.

[0038] Degassing membrane fibers are made of high molecular polymer materials through a special process and have high hydrophobicity and high air permeability. They are a gas-liquid separation membrane with the characteristics of being breathable but impermeable. Degassing membrane fibers are used to establish a stable gas-liquid interface. According to Henry's law and Dalton's law of partial pressure, the pressure and concentration of the gas at the gas-liquid interface are changed to allow the dissolved oxygen in the water to overflow, thereby achieving the purpose of removing dissolved oxygen in the water.

[0039] The degassing membrane assembly 111 is formed by tens of thousands or even hundreds of thousands of degassing membrane filaments through a weaving and winding process and then encapsulated.

[0040] When the membrane deaerator body 1 is in use, external oxygen-free gas enters the shell 13 from the purge gas inlet pipe 19, and the purge gas outlet pipe 110 is connected to an external vacuum pump for providing vacuum. The vacuum pump sucks the gas in the shell 13, and the deoxygenated water enters the water distribution pipe 14 from the water inlet pipe 11 after being filtered by the filter element 22, and then flows into the shell 13 from the through hole 112 of the water distribution pipe 14, and flows on the outside of the degassing membrane assembly 111. Under the negative pressure state of vacuum or oxygen-free gas purge, the oxygen dissolved in the water can pass through the surface of the degassing membrane filaments and enter the degassing membrane core when the water flows through the outer surface of the degassing membrane filaments. The inner cavity of the degassing membrane core is vacuumed or accompanied by purge gas, and the gas is then sucked out by the vacuum pump, while the water cannot pass through, thereby realizing physical separation of gas and liquid. After deoxygenation, the deoxygenated water flows into the water collecting pipe 15 from the through hole 112 of the water collecting pipe 15, and then is discharged from the shell 13 from the water outlet pipe 12, thereby completing water deoxygenation.

[0041] like Figure 2 and 3As shown, in the present embodiment, a retaining ring 26 is fixedly provided in the mounting groove 24, and the retaining ring 26 is located below the top plate 31, and the distance between the retaining ring 26 and the top of the mounting groove 24 is equal to the height of the filter element 22; when installing the filter element 22, the connecting rod 34 is pulled down and rotated until the first screw rod 33 is threadedly engaged with the mounting block 21, and the first screw rod 33 drives the top plate 31 to move down until it abuts against the retaining ring 26, which indicates that the top plate 31 has been moved down into place, and the mounting groove 24 can just accommodate the filter element 22 at this time, and the retaining ring 26 facilitates the staff to confirm whether the top plate 31 has been moved down into place, thereby improving the convenience of use, and the retaining ring 26 supports the top plate 31, and the filter element 22 placed on the top plate 31 is stably placed between the top plate 31 and the cover plate 23, thereby improving the stability of use.

[0042] like Figure 2 and 3 As shown, in this embodiment, an annular sealing ring 27 is fixedly provided at the upper end of the retaining ring 26, and a sealing sheet 28 is fixedly provided at the lower end of the cover plate 23; the annular sealing ring 27 can effectively improve the sealing performance below the filter element 22, and the sealing sheet 28 can effectively improve the sealing performance above the filter element 22, thereby ensuring that the mounting groove 24 has a good sealing effect when water passes.

[0043] like Figure 2 and 3 As shown, in this embodiment, a first handle 35 is fixedly provided at one end of the connecting rod 34 away from the first screw rod 33, a second handle 43 is fixedly provided at the other end of the second screw rod 42, and a third handle 29 is fixedly provided on the cover plate 23; the first handle 35 is convenient for the staff to rotate the connecting rod 34, the second handle 43 is convenient for the staff to rotate the second screw rod 42, and the third handle 29 is convenient for the staff to open and close the cover plate 23, thereby improving convenience of use.

[0044] like Figure 1 As shown, in this embodiment, a mounting base 113 is fixedly provided at the lower end of the shell 13; the mounting base 113 facilitates the installation and fixation of the shell 13 and improves the stability in use.

[0045] Working principle: When the membrane deaerator provided by the present application is in use, after the deoxygenated water is filtered by the filter element 22 from the water inlet pipe 11, it enters the membrane deaerator body 1 for deoxygenation, and the deoxygenated water after deoxygenation is discharged from the water outlet pipe 12; when it is necessary to remove the filter element 22, the second handle 43 is turned to drive the second screw 42 to rotate, and under the thread cooperation of the second screw 42 and the connecting block 41, the second screw 42 is away from the locking groove 25, and the locking fixation of the cover plate 23 and the second screw 42 is released, and the third handle 29 can be grasped to rotate and open the cover plate 23, and then the first handle 35 is turned to drive the connecting rod 34 to rotate, and the connecting rod 34 drives the first screw 33 to rotate, and under the thread cooperation of the first screw 33 and the mounting block 21, the first screw 33 drives the top plate 31 to move up, until the first screw 33 moves up to completely enter the mounting groove 24, the first screw 33 and the mounting block 21 are connected. The threaded fixation of the block 21 is released, and the connecting rod 34 slides into the mounting groove 24. Under the elastic force of the spring 32, the top plate 31 moves up quickly to drive the filter element 22 to quickly pop out of the mounting block 21, and the staff can take out the filter element 22 for replacement. When the filter element 22 needs to be installed later, the first handle 35 is pulled down and the connecting rod 34 is rotated until the first screw rod 33 is threadedly engaged with the mounting block 21, and the first screw rod 33 drives the top plate 31 to move down until it abuts against the retaining ring 26. At this time, the spring 32 is compressed, and the filter element 22 is placed in the mounting groove 24. Then, the third handle 29 is grasped to rotate and close the cover plate 23, and the second handle 43 is rotated to drive the second screw rod 42 to rotate. Under the threaded cooperation of the second screw 42 and the connecting block 41, the second screw 42 is inserted into the locking groove 25, and the second screw 42 can lock and fix the cover plate 23, and the replacement of the filter element 22 can be completed.
