Water purifying device for air conditioning test water system

Abstract

The invention belongs to the field of air conditioning sewage purification and in particular relates to a water purifying device for an air conditioning test water system. The device comprises a water tank and a secondary filter assembly composed of a coarse filter tank and a refined filter tank; a coarse filter water inlet hole and a coarse filter water outlet hole are separately formed in opposite ends of the coarse filter tank, and a coarse filter core formed by an upper flow equalizing plate, a PU foam body and a lower flow equalizing plate is arranged in an overflowing channel formed by an inner cavity of the coarse filter tank between the coarse filter water inlet hole and the coarse filter water outlet hole; a refined filter water inlet hole and a refined filter water outlet hole are separately formed in opposite two ends of the refined filter tank; a mandrel is arranged in the inner cavity of the refined filter tank and the axis of the mandrel is parallel to a water flow forwarding direction of the refined filter tank; the refined filter tank also comprises a PP foam barrel which sleeves the mandrel. The water purifying device provided by the invention has the advantages of being compact and concise in structure and low in using cost, and can remarkably enhance the water purifying efficiency and effect.

Description

technical field [0001] The invention belongs to the field of purification of air-conditioning sewage, and in particular relates to a water quality purification device for an air-conditioning test water system. Background technique [0002] In the water system used for air conditioning testing, there are a large number of water pipes; these water pipes are used to connect the water tank and other water-using devices, such as condensers or evaporators, which are essential components. In actual use, most of the above-mentioned water pipes use stainless steel or galvanized pipes, which makes oxygen ions or chloride ions cause corrosion of galvanized pipes or stainless steel welds or even pipe walls during the working process of the water system, thereby Form rust foam or rust block and pollute water quality. At present, the general measures to deal with the above problems in the industry mostly use chemical drugs, electric ions or ultrasonic waves. The use of chemicals, such a...

Problems solved by technology

The use of chemicals, such as scale inhibitors and dispersants, can certainly achieve effective scale inhibition and purification purposes, but the disadvantage is that chemicals such as scale inhibitors and dispersants are corrosive to metals, which is obviously not conducive to repeated or even long-term use.

The use of ionization to purify air conditioner water has the advantages of removing calcium and magnesium and reducing the hardness of water, and is suitable for industrial use; but the disadvantage is that it is easy to increase the sodium content in water, and it is easy to produce acidic water, and it is also harmful to many organic , inorganic compounds, bacteria, viruses have no effect

The ultrasonic purification method has high efficiency and good water purification effect, but it is relatively high in purchase and maintenance costs, and the working noise is high, which will obviously have a certain impact on the working environment of the staff
