Description

Overflow water distributor and system for uniform renewal of water in the pool

technical field

The invention relates to the technical field of energy storage water distribution, in particular to an overflow water distributor and a system for evenly renewing water in a pool.

Background technique

There are many forms of water storage in the pool, the common ones are labyrinth type, diaphragm type, multi-storage cold water tank type and natural layered type.

The multi-slot hybrid type, also known as the labyrinth type, divides the water storage tank into multiple unit tanks, and the unit tanks are connected in an orderly manner by weirs or connecting pipes. This reduces the volume of the thermocline. However, its structure is complicated, its consumables are many, and its thermal performance is not ideal. This groove type is a more commonly used method when using the underground structure of a building.

The multi-tank switching type of empty and full tanks is composed of more than two storage tanks, one for storing cold water and one for returning hot water, which can ensure that the cold and warm water do not mix. Since this type must be equipped with an empty water tank, the investment and maintenance costs will be increased once. And operation control is more complex, and its application range is narrower.

The natural stratification method utilizes the characteristic that the density of water changes with temperature, and the density of cold water is high, while the density of hot water is small, and the state of stratification can be maintained between cold and hot water. The temperature natural stratification type (vertical flow type) realizes the separation of the return hot water and the cold water in the tank by means of the density difference of the water. Its structure is simple and no artificial isolation facilities are required. The thermal conductivity of water (λ=0.59W/m·k) is lower than that of commonly used building materials (such as concrete, whose λ=0.98W/m·k), therefore, as long as the water temperature in the cold storage tank is stable, the temperature of the cold and hot water Mixing will be affected to a great extent and is currently the most widely used one.

At present, the common structural forms of temperature-layered energy storage water flow distribution devices include pipe network with the same length, concentric casing, water distribution plate, hat-shaped steady flow, and circumferential volute gradual change.

In the layered water cold storage tank, in order to make the water smoothly introduced into the tank (or drawn out from the tank) by gravity flow or plug flow, the key is to install a steady flow diffuser at the cold and warm water inlet of the storage tank. The water is layered sequentially according to the corresponding density difference at different temperatures to form and maintain a stable thermoclinic layer to ensure that the water flow is evenly distributed in the storage tank with little disturbance. The hydrodynamic properties of the thermocline can be determined by the Froude number (Fr) and also affected by the Reynolds number (Re) number. The water distribution settings of natural layered diffuse distribution pipes are mostly octagonal, continuous horizontal slits, radial discs, strips, etc. For the water distribution settings of the above various methods, some of them have poor uniformity due to the long water distribution pipes and the water distribution strength is affected by the resistance along the way. Some (such as strip water distribution) cannot meet the requirements of Reynolds number (Re) due to excessive flow per unit length.
