Cooling type sodium hypochlorite generator

Abstract

The invention relates to a cooling type sodium hypochlorite generator which comprises a reaction tank and an electrode. The reaction tank is provided with a cooling mechanism and a temperature control mechanism. The cooling mechanism comprises a cooling pipe arranged in the reaction tank, a cooling water inlet and a cooling water outlet, wherein the cooling water inlet and the cooling water outlet are formed in the reaction tank. The two ends of the cooling pipe are connected to the cooling water inlet and the cooling water outlet correspondingly. The cooling pipe is of a straight pipe or elbow pipe structure. One or more layers of straight pipes or elbow pipes are arranged in the vertical direction. According to the cooling type sodium hypochlorite generator, the cooling pipe made of a special material is adopted, the generator is ingenious in structural design and has the beneficial effects of being resistant to wear, corrosion and oxidization, stable in chemical property, excellent in heat conduction and the like, and fast cooling and uniform cooling are achieved; a water output tank is arranged, and the flow of cooling water can be controlled precisely; and by the adoption of automatic control of a backstage, the input flow of cooling water can be adjusted in time according to the temperature in the reaction tank, and the cooling range and the cooling rate in the reaction tank are automatically controlled at constant temperature.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a cooling type sodium hypochlorite generator. Background technique [0002] Sodium hypochlorite generator is a kind of water treatment disinfection and sterilization equipment. The equipment uses salt water, industrial salt water or seawater dilute solution as raw material, and generates sodium hypochlorite solution through electrolytic reaction. Sodium hypochlorite is a strong oxidizing agent and disinfectant, usually produced by diaphragmless electrolysis. Compared with chlorine and chlorine compounds, it has the same oxidizing and disinfecting effects. [0003] First, the dilute brine is metered into the electrolytic cell, and the cathode and anode DC power supply is connected through the silicon rectifier to electrolyze to generate sodium hypochlorite. The salt solution contains several ions such as Na+, H-, etc. According to the electrolysis theory, when the electro...
