Therefore, in the electrolysis process, the most critical equipment is the electrolytic cell, and the installation, the operation parameters, the service life and the like of the electrolytic cell are closely related to the electrolysis cost. The electrolytic cell is generally composed of an inner cell body, an outer cell body, a cell cover, a cathode, an anode, a power supply, a gas absorption device and the like, and all the components of the electrolytic cell have influence on the operation and the service life of the electrolytic cell, particularly a graphite anode.
The electrolytic cell is generally divided into two types according to the installation mode of the graphite anode, wherein one type is an upper-insertion type electrolytic cell, and the other type is a lower-insertion type electrolytic cell. The upper-inserting type electrolytic cell is characterized in that a graphite anode is fixed on a cell cover of the electrolytic cell, the upper end of the anode is connected with an electrode through a connecting piece (such as a bolt, a joggle, a lock catch and the like), and the middle-lower section of the anode is inserted into the electrolytic cell and is opposite to a cathode plate; the lower-inserting type electrolytic tank is characterized in that a graphite anode is fixed at the bottom of the electrolytic tank, the lowest end of the anode is exposed to one section and is connected with an electrode through a connecting piece (such as a bolt, a joggle joint, a lock catch and the like), and the middle-upper section of the anode is opposite to a cathode plate in the electrolytic tank.
Both the upper and lower electrolysis cells have some problems, and there is no effective solution for the time being. For example, the anode is connected with the electrode through a connecting piece (such as a bolt, a joggle, a lock catch and the like), the contact area of the connecting position is small, the current is unstable during electrolysis, fluctuation is easy to generate, and the electrolysis efficiency is influenced. The contact area of the connecting position is small, the resistance is large, and the connecting part is easy to generate heat, so that the deformation of the connecting piece is caused, and the service life is influenced. And thirdly, the two graphite anodes have a section of graphite which participates in assembly and fixation, are not opposite to the cathode plate, only provide current and do not participate in electrolysis, and anode graphite waste is caused. And fourthly, the upper end of the upward-inserted anode graphite is in contact with air, so that the upper end of the upward-inserted anode graphite is easily oxidized and corroded at high temperature, and the service life of the upward-inserted anode graphite is influenced. Fifthly, the down-inserting type graphite anode has strict assembly process requirements, high installation cost, inconvenient graphite replacement and higher rejection rate of the tank body. Patent CN202808964U proposes an electrolytic graphite anode, in which a groove is provided at the upper end of the graphite body, a babbitt metal body is cast in the groove, and the babbitt metal body is connected with an aluminum column joint. Patent CN206368201U discloses a clamp for an electrolytic graphite anode and an electrolytic cell thereof, wherein the clamp comprises a clamp body for clamping the graphite anode and a fastening device for locking the clamp body. The two patents can improve the defects of the electrolytic cell to a certain extent by changing the anode connection mode, but are not effective solutions.
