Definitions

  • the present invention relates to an electrolytic apparatus including an electrolyzer.
  • fluorine gases have been used in various applications such as material cleaning and surface modification.
  • the fluorine gases themselves may be used.
  • Various fluoride-based gases such as NF 3 (nitrogen trifluoride) gas, NeF (neon fluoride) gas, and ArF (argon fluoride) gas that are synthesized based on the fluorine gases may be used.
  • Electrolytic apparatuses that generate fluorine gases by electrolyzing HF (hydrogen fluoride) have generally been used to stably supply the fluorine gases.
  • electrolytic baths composed of KF-HF (potassium-hydrogen fluoride) based mixed molten salts are formed in electrolyzers.
  • the electrolytic baths in the electrolyzers are electrolyzed so that fluorine gases are generated.
  • temperatures of the electrolytic baths in the electrolyzers are required to be kept in predetermined ranges to make electrolytic conditions of the electrolytic apparatuses constant.
  • a hot water jacket is provided on a side surface on the outer periphery of an electrolyzer.
  • the hot water jacket includes a hot water pipe and a heat insulating layer.
  • the hot water pipe is provided to surround the side surface on the outer periphery of the electrolyzer.
  • a heat medium heated by a hot water heating device is circulated.
  • a thermometer is provided in the electrolyzer. The hot water heating device heats a heat medium based on a temperature measured by the thermometer, to keep the electrolytic bath in the electrolyzer at a predetermined temperature.
  • At least a cover portion is required to be grounded to a ground having a reference potential in preparation for discharges in the electrolyzer by electric leakage and static electricity.
  • a hot water heating device electric power with large current is handled. Therefore, the hot water heating device is required to be grounded to a ground having a reference potential to ensure safety.
  • the cover portion of the electrolyzer is electrically connected to the electrolyzer through an electrolytic bath.
  • a closed circuit including the cover portion of the electrolyzer, the electrolytic bath, the electrolyzer, the heat medium having conductivity, the hot water heating device, and the ground is formed.
  • electrolization is started using the electrolyzer forming the closed circuit, a current due to a potential difference in the electrolyzer flows in the closed circuit, and electrochemistry corrosion occurs in a metal portion included in the closed circuit.
  • Patent Document 1 discusses a countermeasure using a piping at least a part of which is insulated and a heat medium having high insulation properties.
  • a heat medium being an insulating solvent (e.g., a fluorine-based solvent) and having such a large heat capacity that a temperature of the electrolyzer can be adjusted does not exist. Therefore, an example of the heat medium having a relatively high electrical resistance and having a large heat capacity is pure water. However, the pure water slightly has electric conductivity. Therefore, the above-mentioned electrochemistry corrosion in the metal portion is not completely prevented.
  • An object of the present invention is to provide an electrolytic apparatus capable of ensuring a heat capacity in which a temperature of an electrolyzer can be sufficiently adjusted while reliably preventing electrochemistry corrosion due to a potential difference.
  • an electrolytic apparatus includes an electrolyzer that accommodates an electrolytic bath, a heating unit that heats the electrolyzer using its heat source electrically insulated from the electrolyzer, and a cooling unit that cools the electrolyzer using its heat dissipation source electrically insulated from the electrolyzer.
  • the heat source of the heating unit is electrically insulated from the electrolyzer
  • the heat dissipation source of the cooling unit is electrically insulated from the electrolyzer. In this state, the electrolyzer is heated by the heat source of the heating unit, and is cooled by the heat dissipation source of the cooling unit.
  • the electrolyzer is directly heated and cooled by the heat source and the heat dissipation source, unlike that in heat exchange using a heat medium.
  • a temperature of the electrolyzer can be sufficiently adjusted.
  • a potential is not fed to the electrolyzer via the heat source and the heat dissipation source. Therefore, electrochemistry corrosion in the electrolytic apparatus due to the potential difference in the electrolyzer can be reliably prevented.

  • the heating element of the heater is provided in contact with the outer surface of the electrolyzer with the insulating film interposed therebetween. Therefore, the electrolyzer is directly heated by heat conduction from the heating element of the heater to the electrolyzer. Thus, the electrolyzer can be heated with high responsiveness.
  • the heating unit may include an infrared heating device that radiates infrared rays as the heat source, and the infrared heating device may be spaced apart from the electrolyzer so as to be insulated therefrom.
  • the infrared rays are radiated from the infrared heating device spaced apart from the electrolyzer to the electrolyzer.

  • the blower spaced apart from the electrolyzer blows air to the electrolyzer.
  • the electrolyzer is directly cooled by air circulation.
  • the blower is reliably insulated from the electrolyzer.
  • the cooling unit may include a cooling device having a cooling element that is coated with an insulating film as the heat dissipation source, and the cooling device may be provided in contact with an outer surface of the electrolyzer.

  • the electrolyzer electrically insulated from an installation surface, the heat source, and the heat dissipation source functions as a second electrode. Therefore, a stable and accurate voltage can be applied between the first electrode and the second electrode.
  • the electrolytic apparatus may further include a controller that controls the heating unit and the cooling unit so that a temperature of the electrolytic bath in the electrolyzer is maintained within a predetermined target temperature range.
  • the controller controls heating of the electrolyzer by the heating unit and cooling of the electrolyzer by the cooling unit.
  • a temperature in the electrolyzer can be stably and reliably kept within the target temperature range.
  • the electrolytic apparatus may further include a detector that detects a temperature of the electrolytic bath in the electrolyzer, and the controller may stop an operation of the heating unit while operating the cooling unit when the temperature detected by the detector rises to a first temperature lower than an upper-limit value of the target temperature range, and may operate the heating unit while stopping an operation of the cooling unit when the temperature detected by the detector falls to a second temperature higher than a lower-limit value of the target temperature range.
  • the operation of the heating unit is stopped while the cooling unit operates.
  • the temperature of the electrolyzer can be prevented from exceeding the upper-limit value of the target temperature range due to overshoot.
  • the heating unit When the temperature of the electrolyzer falls to the second temperature higher than the lower-limit value of the target temperature range, the heating unit operates while the operation of the cooling unit is stopped. Thus, the temperature of the electrolyzer can be prevented from being the lower-limit value or less of the target temperature range due to undershoot.
  • the heating unit is stopped while the cooling unit operates, and the heating unit operates while the cooling unit is stopped.
  • an overshoot amount and an undershoot amount at the temperature of the electrolyzer can be reduced.
  • the target temperature range can be reduced, and the temperature of the electrolyzer can be kept substantially constant.
  • the controller may control the heating unit and the cooling unit so that a difference between the upper-limit value and the lower-limit value of the target temperature range is within two degrees.
  • the temperature of the electrolyzer is kept substantially constant. Therefore, an electrolyzation condition is kept substantially constant. Thus, more stable electrolyzation can be performed.
  • the electrolyzer may be an electrolyzer for fluorine generation. Vapor pressure of a fluorine compound used as the electrolytic bath greatly changes with temperature. In such a case, the temperature of the electrolytic bath is also controlled stably and with high accuracy. Therefore, a vapor of a fluorine compound can be prevented from being released from the electrolytic bath in the electrolyzer.
