At this time, each of the main baffle 20, the first sub baffle 30 and the second sub baffle 40 is preferably restrained from each other so as not to fall or shake while being inserted into the case 10.

Thus, the main baffle 20, the first sub baffle 30, and the second sub baffle 40 are constrained together by the fixed beam 50.

In particular, the main baffle 20, the first sub baffle 30, and the second sub baffle 40 are constrained to the fixed beam 50 by various methods.

For example, the fixed beam 50 forms a fixed groove 52 corresponding to the sum of the main baffle 20, the first sub baffle 30, and the second sub baffle 40 along the axial direction, and the main baffle 20. ) And the first sub baffle 30 and the second sub baffle 40 form a coupling groove 54 to be fitted into the corresponding fixing groove 52.

At this time, the chamfer 64 of the chamfer 64 for discharging the gas of the main baffle 20, the first sub baffle 30 and the second sub baffle 40 is determined as a suitable area distribution according to the calculation of the hydrogen gas emissions. .

In addition, as the reaction time continues in the electrolytic reactor using seawater or brine, a large amount of scale is deposited between the positive electrode plate 12 and the negative electrode plate 14, and as the scale accumulates, the electrolytic performance decreases.

In general, the pickling treatment with a low concentration of hydrochloric acid every 10 days to 15 days, and continue to use, drain, pickling, rinsing.

In a state where sticky state and powder form scale are mixed during pickling treatment, washing in the drain state after pickling treatment is not easy and it is desirable to have no congestion section inside.

Thus, the baffles 20, 30, 40 form the baffle guide groove 62 and the fixed beam 50 is fixed beam guide groove 66 for discharging the residue of the scale of the corner portion in contact with the case 10. It is preferable to form.

At this time, since the fixed beam 50 is axially inserted into the case 10, the fixed beam 50 is in contact with the case 10 in a state in which the inclined angle is formed inside the case 10.

In addition, stagnant sections of the inclined corner portions of the fixed beam 50 are generated in the spaces between the baffles 20, 30, and 40, and thus, discharge of electrolyzed seawater or brine from these stagnant sections is caused. It does not work smoothly.

Therefore, it is preferable that the fixed beam 50 forms a fixed beam guide groove 66 to induce a smooth flow of seawater or salt water in the stagnation section.

In this case, the fixed beam guide groove 66 may be variously modified.

As a result, the deterioration factor of the electrolytic reactor is reduced.

4 illustrates another embodiment of the fixed beam guide groove 66 formed in the fixed beam 50.
