Abstract
The invention relates to a method and a device for recovering waste battery electrolyte organic solvent. The recovery of the waste battery electrolyte organic solvent comprises three steps such as 1, opening the case of a single battery, wherein the single battery is of sealed structure, and the internal of the single battery can communicate with the external due to the opening in the battery case of the single battery; 2, decompressing and vaporizing, specifically including exhausting air in the single battery with an opened case in a sealed vaporizing chamber for decompressing, thus allowing the organic solvent of the battery electrolyte to vaporize; and 3, pressurizing and liquefying, specifically including inputting the vaporized organic solvent into a liquefying chamber via a vacuum air pump, and condensing and recovering in the liquefying chamber.
Description
Technical field
The present invention relates to the recycling of old and useless battery, be related specifically to the recycling of the electrolyte organic solvent of old and useless battery.
Background technology
The fast development of new-energy automobile causes needing waste and old electrokinetic cell to be processed to get more and more.The recovery and treatment method of current waste and old electrokinetic cell mainly contains two kinds, and one is burning disposal, the main metallic element material reclaiming battery; One is wet treatment, can reclaim various battery material.The tail gas of burning disposal often causes secondary pollution, unfriendly to environment.The chemicals that wet treatment uses is more, organic solvent easily occurs in the process of process and reveals, pollute production environment.No matter be burning disposal or wet treatment, it is all the major reason that old and useless battery recycling causes secondary pollution that old and useless battery has volatile electrolyte organic solvent.
Summary of the invention
The object of this invention is to provide a kind of method that electrolyte organic solvent to old and useless battery carries out reclaiming separately, reduce the secondary pollution in old and useless battery removal process.Old and useless battery needs to carry out preliminary treatment before electrolyte organic solvent reclaims, and preliminary treatment comprises to disassemble old and useless battery as cell one by one and carries out clean to cell.Old and useless battery electrolyte solvent reclaims and comprises three steps, and the first step is by cell broken shell opening, and cell is hermetically-sealed construction, can make the inside of cell and extraneous conducting at the battery case opening of cell.Second step decompression vapour is sent out, and the cell of shell aperture carries out decompression of bleeding in the vaporizer of sealing, the organic solvent vaporization of battery electrolyte.3rd step is pressurized liquefied, and the organic solvent of vaporization is input to liquefied room through vacuum air pump pressurization, reclaims in liquefied room's condensation.Old and useless battery electrolyte solvent reclaims main device and comprises means for breaking walls, vaporizer, liquefied room, vacuum air pump.Means for breaking walls is mainly in the opening of external wall of cell, and different cells has different means for breaking walls, as puncher, cutting machine etc.Vaporizer is the pressure-reducing chamber of sealing, have vaporizer door, facilitate battery to put into and take out, vaporizer is at least had an aspirating hole and is connected with vacuum air pump by valve, vaporizer can have heater, and heater can heat the battery inside vaporizer.Liquefied room be sealing balancing gate pit, liquefied room has cooling device, and liquefied room is connected with vacuum air pump, through vacuum air pump pressurization organic solvent gas at liquefied room's condensation liquefaction.Vacuum air pump is gas transfer pump, can cause vacuum at population end, can produce relatively high pressure at output.The course of work of the present invention is: through pretreated cell by means for breaking walls in shell aperture, vaporizer put into by the battery of shell aperture, and vaporizer is closed sealing and started heater simultaneously, opens vacuum air pump, and the cooling device of liquefied room starts.Electrolyte organic solvent fast vaporizing under the condition of heating under reduced pressure of inside battery, the gas that the organic solvent of vaporization becomes HTHP through vacuum air pump is input to liquefied room, solvent gas liquefaction after the cooling device cooling of liquefied room of HTHP.
