The invention relates to a method for natural
temperature stratification in a cold accumulation water tank and a device for uniformly distributing and collecting water. The method and the device are characterized in that a cylindrical water distributer is formed in a high position center of the cold accumulation water tank, and is connected and supported at the position by using a water inlet
pipe, the top of the water distributer is close to a water line of the water tank as much as possible; a cylindrical water collector with the same structure as the cylindrical water
distributor is arranged at a lower position center of the water tank, and is connected and supported at the position by using a water outlet
pipe, the bottom of the water collector is close to the bottom of the water tank as much as possible; the
water flow is distributed and the
water flow direction is regulated by using flow equalizing pore plates embedded in the cylindrical water
distributor and the cylindrical water collector, in the way, the water enters the water tank in the horizontal direction, the
water flow rate is reduced, the cold accumulation water tank disturbance caused by the water flow is reduced, the water flow flows into the cold accumulation water tank evenly and slowly in a manner of density current, so as to form the natural
temperature stratification. The water flow is distributed and the water flow direction is regulated by using the flow equalizing pore plates embedded in the cylindrical water
distributor and the cylindrical water collector, in the way, the water flow enters the water tank in the horizontal direction, so as to form the natural
temperature stratification. The method and the device related by the invention have the beneficial effects of simple structure, low cost and uniform temperature stratification of the cold accumulation water tank.
