Description
Technical Field
The utility model relates to an electrolyte water trap especially relates to a water trap for sulfur hexafluoride production electrolyte.
Background
The existing electrolyte dewatering device for sulfur hexafluoride production mainly comprises an electrolytic cell, wherein the top of the electrolytic cell is divided into a large electrolytic cell cover and a small electrolytic cell cover. The big cover of the electrolytic tank is provided with a negative plate and a clapboard, and the small cover of the electrolytic tank is provided with an anode plate. The inner gas phase area of the electrolytic cell is divided into an anode cavity and a cathode cavity by a clapboard and electrolyte on the large cover of the electrolytic cell. The gas in the anode chamber is fluorine gas and the gas in the cathode chamber is hydrogen gas. If the liquid level of the electrolyte in the electrolytic cell cannot play a liquid sealing role, fluorine gas in the anode cavity and hydrogen gas in the cathode cavity are mixed, explosion is immediately generated, production is influenced slightly, the electrolytic cell and corresponding pipelines are damaged seriously, and even the life of personnel is threatened. In addition, the electrolyte has high water content, so that the anode voltage of the electrolytic cell is increased (namely polarization phenomenon) during sulfur hexafluoride production, and at the moment, the electrolytic cell needs to be stopped to replace a small cover of the electrolytic cell, so that the production is influenced, and the liquid level height and the moisture of the electrolyte are very important.
The existing electrolyte has the following water removal:
firstly, a nickel plate is used as an anode plate on the small cover of the electrolytic cell, the small cover of the electrolytic cell is assembled, and meanwhile, the small cover of the electrolytic cell which uses a carbon plate as an anode plate is also assembled; preparing electrolyte, assembling the small cover of the electrolytic cell with the nickel plate to the electrolytic cell, and removing water from the prepared electrolyte. This procedure is about (48-50) hours; after dewatering, the small cover of the electrolytic cell with the nickel plate is detached; pouring out the electrolyte part, and assembling the small cover of the electrolytic cell with the carbon plate as the anode plate into the electrolytic cell.
In summary, the existing electrolyte dewatering device has the following disadvantages:
because the volumes of the nickel plate and the carbon plate are different, the electrolyte needs to be coiled out after the water is removed by the nickel plate, and the small cover of the electrolytic cell needs to be assembled twice, so the process is complex;
the small cover of the electrolytic cell with the nickel plate is disassembled until the small cover of the electrolytic cell with the carbon plate as the anode plate is assembled in the electrolytic cell, the electrolyte is exposed in the air, and the electrolyte can suck the moisture in the air again, so that the water removal effect is reduced, and the production is extremely unfavorable;
the water removal process takes 48-50 hours, which is too long and affects the yield.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects of the prior art and providing a dewatering device without replacing an anode plate.
In order to realize the purpose, the utility model discloses a technical scheme be:
a water removal device for sulfur hexafluoride production electrolyte comprises an electrolytic cell, wherein the top of the electrolytic cell is divided into a large electrolytic cell cover and a small electrolytic cell cover, a negative plate and a partition plate are arranged on the large electrolytic cell cover, an anode plate is arranged on the small electrolytic cell cover, and the anode plate is a carbon plate;
the cathode plate and the carbon plate are communicated with an external power supply through the current controller.
Wherein, the number of the carbon plates is two or more, and the carbon plates are uniformly arranged on one side of the small cover of the electrolytic cell, which corresponds to the electrolytic cell.
The carbon plates are arranged in parallel, and the distance between every two adjacent carbon plates is 3-10 mm.
The utility model has the advantages that: the water removal is performed not by using a nickel plate but directly by using a carbon plate. Assembling a small cover of the electrolytic cell with a carbon plate as an anode plate; meanwhile, preparing electrolyte, and assembling the small cover of the electrolytic cell with the carbon plate as the anode plate to the electrolytic cell; the negative plate and the carbon plate are communicated with an external power supply through a current controller for dewatering, the procedure is about (8-10) hours, the design of the novel process for dewatering the electrolytic cell of the utility model considers the cause of the polarization phenomenon in the production, namely: since polarization is only possible with water, the polarization process is also a water removal process. So, we have chosen the following method: under the different current strength of current controller control, let the carbon plate polarization, begin from the undercurrent earlier, then increase the electric current step by step, constantly polarize to constantly detach the moisture content of electrolyte. The dewatering device has simple working procedures, thorough dewatering and time saving when in use.
