Description of the Invention: [Technical Field 3 of the Invention] Field of the Invention The present invention relates to an electrolysis apparatus, and more particularly to an electrolysis apparatus having an evaporation suppression member. [Background of the Invention] In recent years, there has been proposed an electrolysis apparatus which melts a metal compound such as a chlorinated product and electrically resolves it to produce a metal such as a word. The electrolysis device can dissolve the electrolyte solution obtained by heating a metal compound such as a graphite crucible (electrolytic cell) to a temperature above the melting point, impregnating the electrode and introducing an electric current to decompose the compound such as chlorine and zinc. Wait for the metal. When the above electrolysis device heats the metal compound to a temperature higher than the melting point, a metal compound gas is generated. For example, if the chlorination is heated to 400 ° C above the melting point of about 50 ° C, then one part of the zinc chloride will be vaporized from the molten gas and will rise in the electrolyzer. It gradually cools above the level of the electrolyte, so a large amount of electrolyte mist is generated. The above-mentioned electrolyte gas mist gradually adheres to the inner surface of the exhaust pipe for discharging by-product gas, and 'may cause problems such as blockage of the exhaust pipe. In Japanese Laid-Open Patent Publication No. 2005-200758, there is disclosed a space for venting a by-product gas provided above a liquid surface of an electrolytic solution, and a piping for exhaust gas provided in an upper portion of the space, and The temperature of the upper part of the space is set lower than the temperature of the electrolyte, and the by-product gas and the electrolyte gas mist are convected in the space portion, so that the electrolyte gas mist falls into the electrolyte, and at the same time 5 200925329 toward the exhaust pipe An electrolytic cell structure that feeds a by-product gas. SUMMARY OF THE INVENTION The present invention discloses a problem to be solved by the invention. However, according to the structure disclosed in Japanese Laid-Open Patent Publication No. 2005-200758, when the electrolyte is heated to a higher temperature, the evaporation amount of the electrolyte will be Increasing 'so that the by-product gas and the electrolyte gas mist convect in the space portion, so that the electrolyte gas mist falls into the electrolyte, there will be a certain limit. Further, if the temperature of the heated metal compound is set to be lower, and the temperature of the liquid solution is lowered, the evaporation amount of the electrolyte can be lowered. However, the lower the temperature of the electrolyte, the higher the voltage required for electrolysis, and the higher the liquid resistance of the electrolyte, so that the electric power required for electrolysis is increased. Further, at a lower temperature, the viscosity of the electrolyte increases, and the rate at which the electrolyzed product is detached from the electrode surface is also slowed down, and the electrolysis reaction cannot be continuously performed efficiently. Namely, the temperature of the compound of the heating gold 15 is set to be low to lower the temperature of the electrolyte, which has a certain limit. Accordingly, the present invention has been made in view of the above problems, and an object thereof is to provide an electrolysis apparatus which can reduce the evaporation amount of an electrolyte and prevent the occurrence of clogging of an exhaust pipe without lowering the temperature of the electrolyte. 20 The means for solving the problem is to solve the above problem. One aspect of the present invention is an electrolysis device comprising: an electrolytic cell capable of accommodating an electrolyte; and a heating portion disposed around the electrolytic cell. The electrode portion includes an electrode unit to be immersed in the electrolyte, and an electrode energizing portion for holding the electrode unit and energizing the cover; the cover 200925329 body can separate the closed space from the upper portion of the electrolytic cell; the discharge portion is disposed on the cover body Connecting the closed space to the outside, and discharging the by-product gas generated by the electrolytic solution from the closed space to the outside; and the evaporation suppressing member covers the liquid surface of the electrolyte and forms a floating configuration state of the electrolyte. The by-product gas generated by the 5 electric decomposition is caused to flow to the closed space, and the evaporation of the electrolytic solution is suppressed. According to the electric position of the present invention, it is possible to reduce the evaporation amount of the electrolyte and prevent the occurrence of clogging of the exhaust pipe without lowering the temperature of the electrolyte.

Further, the evaporation amount of the electrolytic solution 7 () is proportional to the exposed area of the liquid phase when the liquid phase and the gas phase are in contact with each other, that is, the liquid surface of the electrolytic solution 70 is proportional to the area in which the space is in direct contact with the space. By using the evaporation suppressing member 60 to float on the liquid surface of the electrolytic solution 70, substantially covering most of the liquid surface of the electrolytic solution 70, and one part of the liquid surface of the electrolytic solution 70 is placed on the second through opening of the evaporation suppressing member 60. 60b and exposed to the structure of the space field 40, even if the temperature of the electrolyte 70 is high, 20 200925329 moderately causes the by-product gas generated by the electrolysis of the electrolyte 70 to flow to the space region 40, and reduces the evaporation of the electrolyte 70. Further, the evaporation suppressing member 60 floats Since it is placed on the liquid surface of the electrolytic solution 7 ,, even if the liquid surface fluctuates up and down by the increase or decrease of the electrolytic solution 7 ,, the vapor-emitting suppressing member 60 can be maintained on the liquid surface of the electrolytic solution 70 to cover it. It can be guaranteed to hold the exposed area of the liquid level and reduce the evaporation amount of the electrolyte. Therefore, according to the configuration of the embodiment, high-efficiency electrolysis at a high temperature can be realized by applying the evaporation suppressing member 6〇. The reaction does reduce the amount of evaporation of the electrolyte 7' to prevent the clogging of the exhaust pipe 53. Further, the second liquid penetration of the liquid surface of the electrolytic solution 70 is appropriately provided. Since the port 60b is generated, the by-product gas generated by the electrolysis of the electrolytic solution 70 can flow from the exposed portion to the space region 40, and the problem of unnecessary residue remaining in the lower portion of the evaporation suppressing member 60 is surely suppressed. The evaporation amount can also reduce the heat release amount of the electrolyte 15, so that the heat insulation effect of the electrolyte 7 增加 can be increased, and the heating efficiency of the heating portion 20 can be improved. The evaporation amount of the electrolyte 70 can be reduced to reduce the electrolyte aerosol. 〇 production 'Therefore, the electrolyte mist attached to the filter 57 can be reduced, and the by-product gas generated by the electrolysis of the electrolyte 7 排出 can be efficiently discharged from the space 40, such as gas. The safety of the electrolysis device is increased. The 'electrode energization portion 30b is formed on the side or below the electrode unit 3a, not above, and extends from the upper side of the electrolyte 7b to be energized, of course, without the evaporation suppressing member 60. The first through hole 6〇a is the same as the following example. (Second embodiment) Next, the electrolysis device according to the second embodiment of the present invention will be described in detail with reference to the drawings. Fig. 4 is a plan view showing the electrolysis apparatus of the present embodiment. Further, Fig. 5 is a view of the arrow B of Fig. 4, and is an enlarged view of the evaporation suppressing member of the present embodiment. Fig. 6 is an enlarged cross-sectional view taken along line B-B of Fig. 4. Ο 10 + The main difference of the electrolysis device 2 of the present embodiment is that, in the first embodiment, the Thai hair suppression member 60 has a structure in which the evaporation suppressing member 80 has been replaced, and the rest of the structures are the same, and the description is appropriately In the present embodiment, the same reference numerals will be attached to the same constructions with emphasis on the above differences, and simplified or omitted.

Further, the evaporation suppressing member 8 has the same structure as the first through opening 60a of the evaporation suppressing member 6 〇 20 of the second embodiment. In other words, the plurality of second through holes 8〇b are straight for the distance between the pair of first through ports 8〇a, 8〇&, _ (the teeth of the counter electrode bars 37 and 37, between the peaks)仏, and only within the range of the inside of the circle 85 through the pair of second through holes 8〇3, 8〇& In other words, the second through-hole 13 200925329 port 80b is limited to the field of the projection shape of the evaporation suppressing member 8A of the electrode unit 30a impregnated in the electrolytic solution 7〇 in the evaporation suppressing member 8A. Therefore, the evaporation suppressing member 80 has a structure in which a plurality of second through holes 580b are provided only in the field corresponding to the upper side of the electrode unit T〇30a impregnated in the electrolytic solution 7〇. Further, the other portion of the evaporation suppressing member 80 which is not provided with the above-mentioned through port 8〇b can realize a structure in which the liquid level of the electrolytic solution 7 is surely covered. Therefore, according to the configuration of the present embodiment, the exposed area of the liquid surface of the electrolyte 7 较小 can be kept small, the evaporation amount of the electrolyte 7 确实 is surely reduced, and the by-product gas of the electrode unit 30 a is immediately decomposed. The direct discharge 10 is efficiently discharged toward the space area 40, so that it is possible to surely suppress the by-product gas from remaining in the lower portion of the evaporation suppressing member 80. Further, by lowering the evaporation amount of the electrolytic solution 70, the heat release effect of the electrolytic solution 7 can be lowered, so that the heat insulating effect of the electrolytic solution 70 can be increased and the heating efficiency of the heating portion 20 can be improved. In the present embodiment, the evaporation suppressing member 80 of the present embodiment is provided with a pair of electrode rods 37 correspondingly penetrating one through the first through holes 80a, and is limited to the electrode unit 30a which is impregnated in the electrolytic solution 70. The structure in which the liquid crystal surface of the electrolytic solution 70 is exposed to the second through hole of the space region 40 is provided in the field of the projection shape of the evaporation suppressing member 8A. Therefore, various second modified examples exemplified below may be derived. Fig. 7 is an enlarged top view showing a modification of the evaporation suppressing member of the embodiment corresponding to the positional relationship of Fig. 5. Specifically, as shown in Fig. 7, the evaporation suppressing member 8A of the present modification is provided with a second through port 8〇Ab', the periphery of the second through port 8〇Ab, and a pair of electrode portions for 200925329. The electrode rods 37 of 30 are continuous with respect to the periphery of the first through-hole 80Aa, and the pair of first through-holes 8A and Ab and the second through-holes 8A are formed as one continuous through-hole. More specifically, the second through-port 80 Ab is located in the field of the projection shape of the electrode unit 3 〇a immersed in the electrolytic solution 7 对 in the evaporation suppressing member 80 A, and further has the corresponding electrode unit 30a. The projected shape is an opening shape that coincides with the projected shape of the electrode unit 3〇a. Therefore, according to the configuration of the present embodiment, only the upper area of the electrode unit 3〇a impregnated in the corresponding electrolyte 7〇 is restrictedly exposed to the space area 10 40, so that a small electrolyte 7 〇 can be kept. The exposed area of the surface does reduce the evaporation amount of the electrolytic solution 70, and the raw by-product gas generated by the electrolysis of the electrode unit 30a is more directly discharged into the space region, so that the by-product can be more reliably suppressed. The gas remains in the lower portion of the evaporation suppressing member 80A. Fig. 8 is an enlarged top view showing another modification of the evaporating member of the embodiment corresponding to the positional relationship of Fig. 5. Specifically, as shown in Fig. 8, in the evaporation suppressing member 8b of the present modification, four second through ports 8〇Bb arranged in parallel are provided, and the pair is the first! The through port 80Ba is lost. Further, the pair of first through holes 80Ba has the same structure as that of one of the evaporation suppressing members 60 of the first embodiment to the second through hole 6〇a. In more detail, the four second through ports 8〇Bb are individually located in the field of the projection shape of the electrode unit 3〇a including the electrolyte solution 70 and the evaporation suppressing member 8A, and further have corresponding electrodes. The four gap portions between the five electrodes 33 of the unit 30a have an opening shape in which the projection shapes of the gap portions separated from the five electrodes 33 are the same. 15 200925329 Therefore, according to the configuration of the present embodiment, only the upper region of the four gap portions between the five electrodes 33 of the electrode unit 3〇a impregnated in the electrolytic solution 70 can be exposed to the space region 40, so that it can be more directly The by-product gas generated by the electrolysis of the electrode unit 30a is efficiently discharged toward the space region 40, so that the by-product gas can be surely prevented from remaining in the lower portion of the evaporation suppressing member 8〇 and kept smaller. The exposed area of the liquid surface of the electrolyte 70 does reduce the amount of evaporation of the electrolyte 70. (Third embodiment) Next, an electrolysis apparatus according to a third embodiment of the present invention will be described in detail with reference to the drawings. Fig. 9 is a cross-sectional view showing the electrolysis apparatus of the present embodiment. Further, the first drawing is a view of the Z arrow of Fig. 9 and is an enlarged view of the evaporation suppressing member of the present embodiment. Fig. 11 is an enlarged cross-sectional view taken along line C-C of Fig. 10. The main difference of the electrolysis device 3 of the present embodiment is that the evaporation suppressing member 80 of the second embodiment has a structure in which the evaporation suppressing member 90 has been replaced, and the remaining structures are the same. Therefore, in the present embodiment, the description will be made focusing on the above differences, and the same reference numerals will be given to the same configurations, and the appropriate description will be simplified or omitted.

The circumferential surface of the first round is separated from the through hole of the inner surface 90w, and there is a case in which the evaporation suppressing member (10) of the first embodiment is opposite to the first and the second embodiment. 200925329 The same structure as port 80a. In other words, the second through hole 9〇b of the plurality of burst suppressing members 90 is formed on the inner surface 9〇w, and the opening diameter d5 of the end portion of the end portion on the side of the electrolytic solution 70 is larger than the end portion of the space side 4〇 side. The through hole of the circumferential surface of the cutting cone. The second through hole 90b has an opening diameter of 2 mm at the end portion on the side of the electrolytic solution 70, and an opening diameter d5 of the end portion on the side of the space 40 is 15 mm.
