Description

Air circulation device in secondary water supply stainless steel water tank

Technical Field

The application relates to the technical field of secondary water supply, in particular to an air circulating device in a stainless steel water tank for secondary water supply.

Background

At present, in urban domestic water pump rooms, except a non-negative-pressure equipment water supply mode, a secondary water supply mode of a stainless steel water tank is mostly adopted. In the tap water production process, in order to ensure the sterilization effect, a tap water company mostly adopts a mode of adding chlorine before leaving a factory. After the tap water enters the secondary water supply tank, the phenomenon of residual chlorine volatilization exists. The existing secondary water supply tank is only provided with one to two small passive ventilation openings, and a large access hole is closed at ordinary times for security reasons. The density of the chlorine volatilized from tap water is higher than that of air, and the chlorine is difficult to discharge only by natural ventilation of the air holes. Over time, a considerable concentration of chlorine builds up in the upper part of the liquid surface inside the tank. Chlorine is highly corrosive and, due to the humid environment in the tank, combines with water droplets condensed on the wall of the tank, forming hydrochloric acid and hypochlorous acid. These two substances can cause corrosion to metal brackets in the tank, tank walls, and other components.

The secondary water supply tank is mostly made of stainless steel, and the rust prevention principle of the stainless steel is that alloy elements form compact oxidation films to isolate nutrient contact and prevent continuous oxidation so as to form corrosion resistance. However, in the water vapor joint portion in the tank, the passive film of stainless steel is easily locally damaged by corrosion for a long time in an acidic environment caused by chlorine gas, and minute corrosion spots are formed. Over time, the rust spots develop and even rust through the tank wall if maintenance is not adequate. This not only influences the life of water tank, also brings certain influence to quality of water safety.
