Description
Technical field:
The utility model relates to the device that electrolytic saltwater is produced the sterilizing agent chlorine bleach liquor.
Background technology
The clorox generating unit of prior art adopts an electrolysis cells.Because the electrolysis cells of clorox generating unit often will clean and keep in repair, the electrolysis cells stopping property is poor, cause blast when preventing hydrogen gas leakage, or the corrosive gases that produces in the electrolytic process produces corrosion to power-supply unit, shorten device work-ing life, for safety, electrolysis cells and electric supply installation (rectifier) must divide the room placement, be placed on separately in the independent room, so floor space is big.In addition, such clorox generating unit is in order to reach higher output, the vertical height of electrolysis electrode is higher, the hydrogen that produces on the electrode can't in time be overflowed and increased the resistance of solution, therefore, electrolytic efficiency is low, and because single electrolysis cells volume is big, the easy short circuit of electrolytic solution and influence electrolytic efficiency.The clorox generating unit has the major part electric weight to be used to the electrolytic solution heating, therefore, must adopt water coolant to cool off, and cooling water waste is serious.Because existing clorox generating unit electrolysis cells electrolytic efficiency is low, poor stability, maintenance load is big; the output of product is little; large-scale production and quality product can not get ensureing, can't be used for the occasion of large-scale application, as large-scale waterworks, power plant or Nuclear power plants etc.
The utility model content
The utility model need solve that clorox generating unit floor space is big, electrolytic efficiency is low, the water coolant requirement is big, single machine yield is low, poor stability, problem that maintenance capacity is big.
The technical solution of the utility model is assemblied by transfer line, dissolved salt case, suspended body flowmeter, ejector, electrolysis cells, titanium tube heat exchanger, rectifier, clorox tank, gas blower, hydrogen discharge device, liquid level switch, it is characterized in that electrolysis cells adopts the electrolysis tube modular unit of plural serial stage, and between many electrolysis tube modular units, add a titanium tube heat exchanger; Electrolysis tube modular unit top is furnished with airtight row's hydrogen production device.
The utility model is owing to adopt the electrolysis tube modular unit of plural serial stage, and between the electrolysis tube modular unit, add a titanium tube heat exchanger, this interchanger only needs few water coolant, the heat heating water inlet that can when inflow temperature is low, utilize electrolysis to produce, when inflow temperature is higher, can introduce water coolant again electrolytic solution is cooled off, electrolytic reaction be remained in the suitable temperature range carry out, making full use of system capacity raising electrolytic efficiency has energy-conservation effect again; Modular electrolysis tube unit sets the airtight row's hydrogen production device of big flow, make the gas that produces in the electrolysis process easily the row's of utilization hydrogen production device collect and get rid of water electrolytic gas, rapid effusion electrode district, reduce the influence of hydrogen to electrolytic efficiency, keep efficient electrolysis, security is good, and it is same indoor that electric supply installation and electrolysis cells can be positioned over, and the plant area area is little; The modular design of electrolysis cells, the output of single device can infinitely be amplified by increasing the electrolysis cells module in theory, and is used for mega project, and the electrolysis cells convenient maintenance and replacement; The available chlorine output of the single electrolysis tube module of the utility model can reach 5Kg/h, the separate unit unit can be made up of eight electrolysis tube modular units at most, and single machine yield can reach the octuple of existing generating unit, therefore, separate unit unit maximum production can reach 40Kg/h, can be used for production occasions such as Large Water Works.
