Abstract
Description
Technical Field
[0001] The utility model relates to the field of chemistry, in particular to electrolysis technology, and in particular to an electrolytic cell device. Background Art
[0002] An electrolytic cell is a device that converts ionic compounds into elements or ions through electrolytic reactions. In the prior art, the cell body of the electrolytic cell includes a left end pressure plate, a left pole plate, a middle pole plate, a right pole plate and a right end pressure plate, which are arranged in sequence from left to right in the cell body. A left injection hole is arranged on the left cell body, and a right injection hole is arranged on the right cell body. The left injection hole and the right injection hole are used as the sewage outlet of the left cell body and the sewage outlet of the right cell body, respectively. KOH alkali water enters the electrolytic cell through the left injection hole and the right injection hole. After running for a period of time, residue is formed inside the cell body, causing blockage. Therefore, it is necessary to discharge the remaining alkali liquid through the left injection hole and the right injection hole, separate and purify it with a separation device, and then inject it from the left injection hole and the right injection hole. The operation is more complicated and the separation and purification cost is higher. In addition, in order to utilize the hydrogen and oxygen generated during the electrolysis process, in the prior art, two hydrogen discharge holes and two oxygen discharge holes are provided on the left tank body, and two hydrogen discharge holes and two oxygen discharge holes are provided on the right tank body. The rear sections of the two hydrogen discharge holes on the single-side tank body are merged to supply gas to the outside. Since the purity of the hydrogen produced by the two hydrogen discharge holes is not always the same, when the purity of the hydrogen produced by a certain hydrogen discharge hole is low, the finally collected hydrogen needs to be re-purified before it can be used, which increases the purification processing volume. The same is true for the oxygen production process. Summary of the invention
[0003] The utility model aims to provide an electrolytic cell device, which aims to solve the technical problems in the prior art that the treatment of residual alkali water is troublesome and the amount of hydrogen and oxygen purification processing is high.
[0004] The utility model discloses an electrolytic cell device, comprising a cell body, in which a left end pressure plate, a left pole plate, an intermediate pole plate, a right pole plate and a right end pressure plate are sequentially arranged from left to right in the cell body, a left liquid injection hole is arranged on the left side of the cell body, a right liquid injection hole is arranged on the right side of the cell body, a left circulation liquid outlet and a left circulation liquid inlet are arranged on the left cell body, the left circulation liquid outlet is connected with the left circulation liquid inlet through a left pipeline, a first filter, a first pump body and a first valve are sequentially arranged on the left pipeline, two mutually separated left hydrogen discharge holes and two mutually separated left oxygen discharge holes are arranged on the left cell body, a right circulation liquid outlet and a right circulation liquid inlet are arranged on the right cell body, the right circulation liquid outlet is connected with the right circulation liquid inlet through a right pipeline, a second filter, a second pump body and a second valve are sequentially arranged on the right pipeline, and two mutually separated right hydrogen discharge holes and two mutually separated right oxygen discharge holes are arranged on the right side of the cell body.
[0005] Compared with the prior art, the utility model has a positive and obvious effect. Alkali liquid is injected into the electrolytic cell through the left injection hole and the right injection hole, and hydrogen and oxygen are decomposed through electrolysis. Hydrogen and oxygen are discharged from the left hydrogen discharge hole and the right hydrogen discharge hole and the left oxygen discharge hole and the right oxygen discharge hole respectively. The two hydrogen discharge holes and the two oxygen discharge holes are separated from each other and are not connected to each other. The hydrogen or oxygen with higher purity does not need to be purified again, which reduces the purification processing amount. During the electrolysis process, the pump body is opened regularly, and the remaining alkali liquid is pumped out from the left circulation outlet and the right circulation outlet, and the residue is filtered through the filter, and then pumped into the tank body through the left circulation inlet and the right circulation inlet to reflow and reuse, thereby improving the utilization rate of the alkali liquid, and can also reduce the frequency and processing volume of subsequent separation and purification, and reduce the separation and processing costs. The injection hole is no longer used for drainage, which can reduce blockage. BRIEF DESCRIPTION OF THE DRAWINGS
