A purification device for circulating water in a heat exchange system

Abstract

The invention discloses a purifier for circulating water in a heat exchange system; the purifier includes a heat exchange system circulating water header pipe, a split flow pump, an electron flocculator, a condenser, a centrifugal separator, a filth collector, and an electron scale-removal algae-removal device; both ends of the heat exchange system circulating water header pipe are connected with the heat exchange system, one end of the heat exchange system circulating water header pipe is also connected with an inlet of the split flow pump, and the other end of the heat exchange system circulating water header pipe is also connected with an outlet of the electron scale-removal algae-removal device; the split flow pump, the electron flocculator, the condenser, the centrifugal separator and the electron scale-removal algae-removal device are connected in order, and the centrifugal separator also is connected with the filth collector. The purifier adopts a way that a part of circulating water is led out and treated and the circulating water after treatment is sent back to the heat exchange system; the flow quantity of treatment is little, the centrifugal separator with higher treatment precision can be used, at the same time, the environmental-protection electric flocculation technique can be used, and disadvantages of adding chemical agents are solved.

Description

technical field [0001] The invention relates to the technical field of purification treatment of heat exchange circulating water in a central air-conditioning and heating system, in particular to a purification device for circulating water in a heat exchange system. Background technique [0002] The circulating water used for heat exchange in central air-conditioning and heating systems will produce impurities such as various fine suspended particles, dissolved colloids, algae and bacteria during operation. The traditional method of removing these impurities is to install filters on the circulation pipes and in the water The method of putting in chemical flocculant and sterilizing agent is used for treatment, and the water flow rate during this method is large. If high-precision filtration and an automatic cleaning filter device are required, the size of the filter will be large and complicated, and the use of chemical flocculants also requires additional environmental prote...

Problems solved by technology

If high-precision filtration and automatic cleaning filter device are required, the size of the filter will be large and complicated, and the use of chemical flocculants also requires additional environmental protection treatment equipment

[0003] In addition, due to the large flow rate, it is very difficult to adopt more environmentally friendly electronic flocculation technology and centrifugal separation technology with higher cleanliness. The processing device is not only too bulky to match the heat exchange circulation system, but also practically Unrealistic due to high cost and uneconomical
