Card insertion type membrane electrolysis device

The present invention is regarding a kind of oxide generation device, particularly a kind of card insertion type membrane electrolysis device wherein its anode plate and membrane is of insertion type and can be pulled out any time for inspection.

The ordinary membrane electrolysis device in general has an anode plate, a cathode plate and at least one membrane. The membrane only allows water and ions to pass through in order to separate the anode and cathode plates of the electrolysis device, forming semi-separation anode chamber and cathode chamber. The membrane electrolysis device is used in the high voltage, low PH value electrolytic salt water for the generation of strong oxide such as chlorine dioxide (ClO₂), chlorine gas (Cl₂), and ozone (O₃), etc. Using such oxide compound in processing material, the function of sterilization, deodorization, and disinfections can be achieved. Also, many kinds of free radicals with very strong oxidation ability can be generated for the use of oxidizing organic substance and eliminating organic substance harmful to human body.

The ordinary membrane electrolysis device has anode plate and membrane fixed in the electrolysis device, therefore servicing people could not easily obtain the wear-off condition of anode plate and membrane, resulting in difficulty in the inspection and maintenance of anode plate and membrane. And when the electrode plates and membrane are damaged, the removal and replacement also poses problems. The traditional machine usually takes more than two hours to replace electrodes and membrane, which costs time and manpower. Also, traditional machine is huge in size and fixed in generating gases, leading to expensive manufacturing price and operational cost.

In view of ordinary membrane electrolysis device is having fixed design for its anode plate and membrane, which is not easy for inspection and replacement, the purpose of the present invention is to propose a kind of insertion type membrane electrolysis device with insertion card design for its anode plate and membrane.

Hence it is easy to inspect and replace the anode plate and membrane, saving large amount of manpower and time.
