Therefore, the mobile both sides that hydrogen contained in reduction dialysis solution stock solution and the reduction dialysis solution stock solution is arranged in pipe 82.Hydrogen is transported in first membrane module 30 through pipe 12.That is, be connected in first membrane module 30 by the pipe 82 with tertiary membrane assembly 80 and carry on the pipe 12 as the liquor charging pipe arrangement of stock solutions, and carry out the remix of hydrogen.By like this, can effectively utilize hydrogen.
At this, used apparatus for electrolyzing 50 as hydrogen gas supplying apparatus, still, also can not use apparatus for electrolyzing 50 and use the High Pressure Hydrogen gas cylinder that is packaged with hydrogen with the form of high pressure.In addition, also can dispose tertiary membrane assembly 80.In addition, also the pipe 82 that comprises the hydrogen that is separated by tertiary membrane assembly 80 can be connected on the pipe 37 rather than manage on 12.In addition, thus also pipe 82 can be connected pipe makes on 32 pipe 82 open wide to the outside of dialysis solution or stock solution hydrogen reduction device 1.
And then pipe 32 also can open wide rather than be connected on the filter 10 to the outside of dialysis solution or stock solution hydrogen reduction device 1.Allocation position and the quantity of first pump 20 and second pump 60 do not have any restriction, as long as can be from first membrane module 30 to forbay 70 carry out liquor charging and forbay 70 is pressurized to more than the atmospheric pressure, just can go up the pump of configuration any amount at an arbitrary position.In addition, forbay 70 also can be the roughly the same tubular part of pipe of diameter and its entrance side or outlet side.
Fig. 2 roughly represents to utilize stock solution before dialysis solution shown in Figure 1 or stock solution hydrogen reduction device mix from hydrogen to make the flow chart of the flow process of the reduction dialysis solution stock solution after the hydrogen reduction.
At former dose of dialysis solution during for liquid (this state is called " stock solution "), this stock solution is transported in first membrane module 30 via pipe 5, thereby directly is conducted to during the degassing handles.On the other hand, when former dose of dialysis solution was powder, will this former dose being dissolved in the water formed liquid (will form aqueous material and be also referred to as " stock solution "), and this stock solution is transported in first membrane module 30 via pipe 5, thereby was conducted to during the degassing handles.
It is the processing that the dissolved oxygen in the stock solution etc. is removed that the degassing is handled, help after the hydrogen dissolution process in the concentration of hydrogen in the liquid of raising after being dissolved in the hydrogen dissolution process.Stock solution after the degassing is handled is then mixed with hydrogen, thereby is conducted in the hydrogen dissolution process.Hydrogen is to carry out in second membrane module 40 to the dissolving in the stock solution, and also carries out under the environment under high pressure in forbay 70.The catabolite (for example Biformyl) that hydrogen helps the glucose degradation in the stock solution is generated reduces.
The reduction dialysis solution stock solution that is sent to the downstream from forbay 70, contain the hydrogen that is dissolved in the reduction dialysis solution stock solution and remains the molecularity that exists after the reduction of degradation of glucose product sometimes.Therefore, under this situation, for this hydrogen is removed, and carry out the operation of utilizing tertiary membrane assembly 80 optionally hydrogen to be separated from reduction dialysis solution stock solution.
Fig. 3 represents the structure (3A) of second membrane module shown in Figure 1 and the ideograph (3B) that describes for the structure of the hydrogen that will exist across the film that constitutes the doughnut sidewall being mixed with the dialysis solution stock solution of doughnut inside and make hydrogen be dissolved in stock solution.
When the downstream at doughnut 101 was moved second pump 60, the downstream of doughnut 101 and the inboard of sidewall became negative pressure.Consequently, the stock solution in the doughnut 101 flows towards the direction of second pump 60, and hydrogen 102 enters the inside of doughnut 101 and flows with the direction of stock solution towards second pump 60 from the hole.
Generally speaking, when making gas dissolving in liquid, make method that gas foams in liquid by cognition in view of dissolving difficulty.But in common foaming method, the size of bubble is big to millimeter level～hundreds of micron orders, also inadequately little under the situation in the instantaneous stock solution that is dissolved in dialysis solution with making the hydrogen high concentration as present embodiment.Therefore, in the present embodiment, will have the sidewall of doughnut 101 in the hole 102 of a large amount of dust levels, utilize as the device that in stock solution, produces the hydrogen gas bubbles V littler than hole 102.Consequently, can in stock solution, form minimum hydrogen gas bubbles V (than the little bubble V of the diameter in hole 102), thereby hydrogen is dissolved in the stock solution with higher concentration.
Like this, in the present embodiment, a large amount of doughnuts 101 are banded together, and the sidewall at each doughnut 101 arranges a large amount of hole 102, generates the dust level bubble littler than the diameter in hole 102 thereby forcibly make from managing 42 hydrogen that enter into sleeve pipe 100 in the stock solution of doughnut 101.Therefore, can enlarge markedly the contact area of stock solution and hydrogen, hydrogen is dissolved in the stock solution with higher concentration.
In addition, in the above-described embodiment, utilize the example that hydrogen is dissolved in the stock solution (A agent) to be illustrated, still, in the dialysis solution that hydrogen is dissolved in the B agent by replacing the A agent or is made by A agent and B agent and reduce, also can significantly reduce the oxidation-reduction potential of dialysis solution.
