Abstract

The invention discloses a surface treatment device and method for an electrolytic cell flow field material, and relates to the technical field of surface treatment of electrolytic cell flow field materials. The problems that electrolytic cell flow field material surface treatment is low in efficiency and high in cost are solved. The device specifically comprises a shell, an inner cylinder is arranged in the shell, a sealing groove is formed in the outer wall, close to the top of the inner cylinder, of the shell, a top cover is connected to the outer wall of one side of the top of the shell through a hinge, and an air inlet and an air outlet are formed in the outer wall of the back face of the shell. The inner walls of the air inlet and the air outlet are in threaded connection with guide pipes; heating pipes distributed at equal intervals are connected to the circumferential inner wall of the bottom of the inner cylinder through bolts; a temperature sensor is fixed to the inner wall ofthe bottom of the inner cylinder through bolts, a conical base is welded to the outer wall of the bottom of the inner cylinder, and the outer wall of the bottom end of the conical base is in threadedconnection with a feed liquid circulating port. The device is simple in overall structure, convenient to install and low in cost, and multiple operation processes can be completed in one device in acentralized mode.

Description

technical field [0001] The invention relates to the technical field of surface treatment of electrolytic tank flow field materials, in particular to a surface treatment device and surface treatment method for electrolytic tank flow field materials. Background technique [0002] The electrolyzer is a key component in the hydrogen-oxygen ventilator, which plays the role of producing hydrogen and is the heart of the hydrogen-oxygen ventilator. With the rapid development of hydrogen medicine, the demand for electrolyzers has also increased. The flow field material is one of the key materials of the electrolytic cell, which has an important impact on the performance of the electrolytic cell. Treating it with certain technical means can achieve the purpose of corrosion resistance, thereby improving the output performance of the electrolytic cell and prolonging its service life. As the demands on electrolyzers increase, rapid processing of flow field materials becomes a top priori...
