Intermittent electrolytic salt sodium hypochlorite generator suitable for small water supply projects in rural areas

Abstract

The invention discloses an intermittent electrolytic salt sodium hypochlorite generator suitable for small water supply projects in rural areas. An electrolytic tank is arranged. An electrolysis electrode is fixed to the low end in the electrolytic tank. A cooling pipe is fixed to the upper portion of the electrolytic tank. An alternating current power supply switch, a direct current switching power supply and a direct current inverse-electrode switch are connected in series through a cable to be then connected with the electrolysis electrode. A reverse osmosis water purifier is communicated with the electrolytic tank through a pipe. The arranged cooling pipe starts cooling after electrolysis is carried out for 3-4 h, it can be effectively guaranteed that an electrolyte is stable and does not exceed 25 DEG C, and the later electrolysis condition is improved; purified water is used for preparing a salt solution so that the electrode can be effectively prevented from scaling; the same material and coating are adopted in the negative pole and the positive pole of the electrolysis electrode, the direct current inverse-electrode switch is used for alternate inverse-electrode electrolysis, and therefore scale on the electrode can be effectively removed; and the disinfectant dosage needed by the water supply projects for 1-5 days can be met when a sodium chlorate solution is produced each time. In addition, the intermittent electrolytic salt sodium hypochlorite generator is simple in structure and easy and convenient to operate and manage, and the disinfection needs of the small water supply projects in the rural areas can be met.

Description

technical field [0001] The invention belongs to the technical field of sodium hypochlorite generators, in particular to an intermittent electrolytic salt sodium hypochlorite generator suitable for small rural water supply projects. Background technique [0002] The current electrolytic sodium hypochlorite generator is mainly continuous type, and its intermittent operation will reduce the life of the electrode. Since most of the small rural water supply projects are intermittent operation (not running late at night), the current electrolytic sodium hypochlorite generator is not suitable for small rural water supply projects; Most of the intermittent electrolytic sodium hypochlorite generators have no cooling function. In order to reduce the electrolysis temperature in the later stage, a small current mode is adopted, and the electrolysis time is long or even exceeds 16 hours; most of them use pickling to remove the scale on the electrode, which is not suitable for the manageme...
