The utility model has the functions of descaling and scale prevention, and the anti-corrosive function.

Description

Rot-proof contaminant releasing device for equipment using water

The utility model belongs to water treatment device.Mainly be applicable to industrial water system and heating water system.

In industrial water system and heating water system, relevant devices that contacts with water and inner-walls of duct be fouling easily all, even produces corrosion phenomenon.It not only influences the normal operation of water system, causes energy consumption to increase, even accident such as plugging takes place.

In order to solve scale removal, the antiscale problem in the above-mentioned water system, most of chemical process that adopts is carried out pre-treatment to water in the prior art, as ion-exchange, desalination, or adopts inhibiter, Scale inhibitors etc.Though these methods can obtain certain effect, but still there is weak point, it mainly is bad adaptability to water, need the special messenger to monitor, the expense height uses trouble, and should not be used for some specific occasions, adopt methods such as ion-exchange, desalination as the GEOTHERMAL WATER heating system, will lose the value of utilizing geothermal energy.Simultaneously, aforesaid method function singleness.

The described electronic hydrotreater of Chinese patent CN90212341.6 is to utilize low voltage, little electric current to change the physicochemical property of processed water, thereby reaches the purpose of antiscale, scale removal.This water treating device has water pollution-free, good stability, and low cost and other advantages, but this electronic hydrotreater does not have anti-corrosion function.

The purpose of this utility model be to provide a kind of can scale removal, antiscale, have the anticorrosion cleaner of watering equipment of anti-corrosion function again.

Main technical schemes of the present utility model is that an aluminium alloy bars is equipped with as anode in the center of this anticorrosion cleaner, and the housing of anticorrosion cleaner is made by zinc-plated weldless steel tube, as negative electrode.Connecting portion between anode and the negative electrode adopts tetrafluoroethylene to insulate.The housing lower end relative with the anode end is cone-shaped, connects mudhole down.Pass to direct current between anode and the negative electrode.Under galvanic effect, the reaction that produces electrolysis between aluminum alloy anode and the housing negative electrode, positively charged ion and water effect that electrolysis generates, and generate secondary product, and this secondary product is a colloid, absorption property is strong, has significant corrosion inhibition.Secondary product flows in the equipment and pipeline of water system through the water outlet place, and attached on the inwall, forms protective membrane, and its internal surface is had preservative activity.The colloid reaction thing that sedimentary dirt and minute quantity are deposited in the anticorrosion cleaner in the anticorrosion cleaner can regularly be discharged by cone-shaped lower end mudhole.

The utility model compared with prior art has following advantage:

(1) can not only descaling and antiscaling, and also have anti-corrosion function.

(2) adaptability to water is strong, improves the heat energy utilization rate of water;

(3) simple, small and exquisite, the less investment of device.

(4) convenient operation and management.

Now the utility model is described in further detail in conjunction with the accompanying drawings.

Accompanying drawing is the structural representation of the anticorrosion cleaner of the utility model watering equipment.

Among the figure, 1 is upper press cover, and 2 is insulation covering, and 3 is water outlet, and 4 is housing (negative electrode), and 5 is aluminium alloy bars (anode), and 6 is water-in, and 7 is mudhole, and 8 is stopping valve, and 9 is direct current stabilizer, and 10 is the direct current service wire.Anode 5 insulate with teflon insulation cover 2 with negative electrode 4 connections; The lower end of housing 4 is a cone shape, and communicates with mudhole 7; Galvanic positive pole links to each other with aluminium alloy bars anode 4, and negative pole links to each other with shell 4.

Claims

A kind of anticorrosion cleaner of watering equipment is done housing with zinc-plated weldless steel tube, as negative electrode, the housing center is furnished with anode, insulate with tetrafluoroethylene between anode and the negative electrode, pass to galvanic current between anode and the negative electrode, it is characterized in that with the aluminium alloy bars being the anode at housing center; The lower end of housing is a cone shape, and communicates with its following mudhole.
