Description
Technical Field
The invention relates to the technical field of energy storage water distribution, in particular to an overflow water distributor or a system for uniformly updating water in a water tank.
Background
There are many forms of water storage in the pool, and there are labyrinth type, diaphragm type, multi-cold-storage water tank type and natural layering type.
The multi-groove mixed type is also called labyrinth type, the water storage tank is divided into a plurality of unit grooves, the unit grooves are orderly connected by a weir or a communicating pipe, and the tortuous flow passage reduces the interface area of the reflux hot water and cold water, thereby reducing the volume of the inclined temperature layer. But the structure is complex, the material consumption is high, and the thermal performance is not ideal. The trough is a more common way of utilizing the underground structure of a building.
The empty and solid tanks multi-tank switching type water tank consists of more than two storage tanks, one for storing cold water and one for storing backflow hot water, so that the cold water and the hot water are ensured not to be mixed.
The natural layering is to use the characteristic that the density of water changes along with the temperature, and the density of cold water is high, the density of hot water is low, and the layering state between the cold water and the hot water can be kept. The temperature natural layering type (vertical flow direction type) realizes the separation of the reflux hot water and the cold water in the tank by means of the density difference of the water, and has simple structure without the need of an isolation facility constructed manually. The coefficient of heat conductivity (lambda=0.59W/m.k) of water is lower than that of common building materials (such as concrete, lambda=0.98W/m.k), so that only the water temperature in the cold storage tank is required to be layered stably, the mixing of cold and hot water is greatly influenced, and the cold and hot water is one of the most applied types at present.
The structure forms of the current common temperature layered energy storage water flow distribution device comprise a same-path pipe network, concentric sleeves, a water distribution disc, a cap-shaped steady flow, gradual change of a circumferential volute and the like.
In the layered water cold storage tank, in order to lead water into the tank (or led out from the tank) stably by gravity flow or piston flow, a stable flow diffuser is required to be arranged at the cold and warm water inlet of the tank, so that the water is layered in sequence according to the corresponding density differences of different temperatures, and a stable inclined temperature layer is formed and maintained so as to ensure uniform distribution of water flow in the tank and small disturbance. The hydrodynamic properties of the bias temperature layer can be determined by Fr and also by Reynolds number (Re) standards. The distribution arrangement of the natural layered diffusion distribution pipe is mostly octagonal, continuous horizontal slit type, radiation disc type, strip type and the like. The water distribution of the above methods is provided, and the water distribution strength is affected by the resistance along the way and the uniformity is poor because of the longer water distribution pipe. Some (such as bar-shaped water distribution) cannot meet the requirement of Reynolds number (Re) due to overlarge flow rate per unit length.
