Abstract

The utility model discloses a water purifier which is a novel water treatment device and comprises a DC power supply box of low voltage, an insulation cylinder, a positive electrode, a voltammeter and a regulation knob. When used, the utility model is directly arranged on the water pipe in a circulation water system. Low-voltage electrostatic field generated between the positive electrode in the water purifier and a water pipe wall directly conducts the water treatments of scale removing and prevention, corrosion prevention, sterilization and algae removing to the raw water in the circulation water system. The water purifier adopts the water pipe to replace the large and heavy shell of the prior water treatment device. Thus the cost is reduced with convenient manufacture, transportation and installation. The device installation field is saved. The installation and the reform for building the circulation water system or using the circulation water system are convenient.

Description

Water purifier

A kind of water treatment tank relates to antiscale, scale removal, anticorrosion, the sterilization algae removal treatment technology of water body, is applicable to the processing (as air-conditioning and cooling water system) of circulating water system to incrustation scale and microorganism.

At present chemical process or electronic technology method are adopted in the scale removal of circulating water system, anticorrosion, sterilization usually.Adopt not only expense height of chemical process (in recirculated water, adding Scale inhibitors, sanitas etc.), also can cause secondary pollution, adopt the electronic technology treatment process, electrode in the electronics water treatment device is made complicated, cost an arm and a leg, and the volume of entire treatment device increases with the increase of water treatment amount, therefore, make, transport, install and all compare difficulty, in building circulating water system, also be required to be the special fabricating yard of this device design, then can't adopt this device the circulating water system in usefulness.

It is a kind of simple in structure that the purpose of this utility model is to provide, and volume is small and exquisite, makes, convenient transportation, do not need special fabricating yard, and cost is low, installs, safe in utilization, water treatment tank easily.

The utility model realizes that in the following manner the top of water treatment tank is a low-voltage dc power supply case, and the power supply box casing is as the negative electrode of water treatment tank, and its top is sexangle, and the bottom is that circle is shaped on connecting thread.The bottom of water treatment tank is the bar-shaped positive electrode that is made of metal, adopt insulating material to separate between negative electrode and positive electrode, insulation, during installation positive electrode is stretched in the water pipe, screw thread by the power supply box lower box is directly installed on the metallic conduit of circulating water system, and this moment, the metallic conduit wall also became the negative electrode of water treatment tank.Positive electrode and water pipe formation low pressure electrostatic field carries out antiscale, scale removal, anticorrosion and sterilization algae removal processing to continuous mobile water body in the water pipe during work.

Advantage of the present utility model is: water treatment tank directly is fixedly mounted on the pipeline of circulating water system, substituted the huge and heavy housing that present used water treatment device must have with water pipe, therefore its volume is small and exquisite, in light weight, make and transport very convenient, greatly reduce the cost of water treatment tank, saved the fabricating yard of water treatment device, and, use safely no matter be to install easily in the circulating water system of founding a capital or in the circulating water system of usefulness.Because water purifier is directly installed on the water pipe, the low pressure electrostatic field that produces between positive electrode and water wall acts directly in the former water system of circulation, rather than allow circulating water flow through a special water treatment device, can make the calcium ions and magnesium ions in the former water can not form compact crystal and hard incrustation scale like this, improved the efficient of antiscale, scale removal, low-voltage DC produces active oxygen radical to little electrolytic effect of former water water body is carried out sterilization, algae removal, rotproofing simultaneously.

Accompanying drawing is the utility model embodiment, wherein:

Fig. 1, the utility model synoptic diagram;

Fig. 2, structural representation of the present utility model.

In conjunction with the accompanying drawings the utility model is further described.

The utility model is by low-voltage dc power supply case 1, insulating cylinder 3, positive electrode 4, volometer 5, voltage-regulation knob 6, current adjusting knob 7 constitutes, the casing of low-voltage dc power supply case is as negative electrode of the present utility model, its upper periphery is sexangle, and the centre on top is a circular shrinkage hole, and its underpart periphery is garden shape and is shaped on screw thread 2.The insulating cylinder of making by the tetrafluoroethylene insulating material 3 tightly be wrapped in the top of positive electrode 4 and positive electrode 4 together tightly sealing be inlaid in the low-voltage power supply case 1 bottom intermediary circular hole and firmly fuse with low-voltage dc power supply case 1.External source transformation behind low-voltage dc power supply case 1 becomes 3～5V low-voltage DC, and the positive pole of low-voltage DC is connected with positive electrode 4 by bolt 8, and negative pole is connected with the low-voltage dc power supply box body.The voltage and current of low-voltage DC is harmonized by voltage-regulation knob 6 and current adjusting knob 7 by volometer 5 indications.

The utility model (positive electrode size: diameter 25mm, long 860mm) is installed in the 800T/H air conditioning cooling water system, carries out water treatment.Before the processing, total plate count is 2.0 * 10 in the water ⁵Individual/milliliter, calcium carbonate crystal is the stratiform dense structure, behind the fortnight in the water total plate count be 5.7 * 10 ⁴Individual/milliliter, total plate count is 3.0 * 10 in the water after two months ³Individual/milliliter, and calcium carbonate crystal becomes pine needle shape structure in the water, does not see that pipeline corrosion increases.
