Abstract
The utility model discloses a water distribution disc for a heat accumulator. The water distribution disc comprises an external pipe section, an upper sealing plate, a water distribution grille, a lower sealing plate, a shunt clapboard and a water flow inlet/outlet, wherein the bottom of the water distribution disc consists of the lower sealing plate; the lower sealing plate and the upper sealing plate above the lower sealing plate are supported through the shunt clapboard are form a water distribution cavity; the inner edge of the upper sealing plate is connected with an external pipeline; the depth of the upper sealing plate is downwards folded to form a small-slope water distribution cavity; the lower sealing plate is of a regular octagon, and eight diamond-shaped hollow spaces are formed in the middle of the lower sealing plate; the water distribution cavity is separated into eight water flow channels through the shunt clapboard; and the tails of the channels are in transition to form the rectangular flat water flow inlet/outlet of the water distribution grille. According to the water distribution disc, the materials are saved, the construction cost is reduced, a water distributor is uniform in water flow, the water pressure is stable, the thickness of a turbulent region and the water flow turbulence of a main body section are reduced, and the water distribution disc is suitable for high-temperature-difference heat accumulation.
Description
Technical field
The utility model relates to a kind of water distributing tray of the heat accumulator system take water as medium.
Background technology
The storage heater of using in China at present is mainly the small-sized storage heater that cooperates solar thermal utilization, and the large-scale storage heater construction above 1000 cubic metres relatively seldom.The Engineering Projects of domestic water cold-storage is a lot, but because the hot and cold water temperature difference of water cold-storage is less, the trend that produces turbulent phenomenon in the chilled water tank body is very little, and layered effect is good, so low temperature water system is not high to the designing requirement of water distributing tray.But for large temperature difference storage heater, if the unreasonable structure of water distributing tray or the control of current had a little deviation produces turbulent flow after will causing hot and cold water to enter the storage heater tank body, destroy the layering of hot and cold water, reduce heat storage capacity.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of water distribution disk of heat accumulator, this storage heater water-locator is considered the application of the large temperature difference storage heater of high temperature, the control heat supply network enters the current of storage heater tank body for backwater, guarantee the accumulation of heat quality, and overcome the problems such as traditional water distribution disk of heat accumulator waste of material and current shakiness.
Technical problem to be solved in the utility model is achieved through the following technical solutions: this water distribution disk of heat accumulator comprises external pipeline section, upper sealing plate, divide the water grid, lower shrouding, split-flow baffles, the Water Exit head piece, described water-locator chassis is comprised of lower shrouding, support and form the cloth water chamber by split-flow baffles between the upper sealing plate of lower shrouding and its top, the edge connects external pipe in the upper sealing plate.
Folding forms light grade cloth water chamber under the described upper sealing plate degree of depth, and lower shrouding is octagon, has between eight rhombus vacancy sections on upper sealing plate and the lower shrouding.Split-flow baffles is 16, and it is eight pipelined channels that the cloth water chamber is separated, and it is eight pipelined channels that split-flow baffles separates the cloth water chamber, and the transition of passage afterbody is the flat rectangular shape Water Exit head piece that is provided with minute water grid, and a minute water grid is comprised of the little grid of rhombus.
Beneficial effect:
1, adopts the hollow type water distributing tray, save material, reduce quality, reduce cost.
2, current evenly distribute on the whole cross section of casing, have reduced turbulent region thickness and the turbulent fluctuation of main body current section.
3, the Water Exit head piece is flat, eliminates vertical component, and flow velocity is even, stable water pressure.
4, be applicable to large temperature difference accumulation of heat.
Description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model structure top view
Fig. 3 is minute water grid schematic diagram among Fig. 1
Among the figure: 1. external pipeline section, 2. upper sealing plate, 3. minute water grid 4. descends shrouding, 5. split-flow baffles, 6. Water Exit head piece.
The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is further described.
As shown in fig. 1, this water distribution disk of heat accumulator comprises external pipeline section 1, upper sealing plate 2, divide water grid 3, lower shrouding 4, split-flow baffles 5, Water Exit head piece 6, described water-locator chassis is comprised of lower shrouding 4, supports and form the cloth water chamber by split-flow baffles 5 between the upper sealing plate 2 of lower shrouding 4 and its top, and upper sealing plate 2 is interior along connecting external pipe 1.
Folding forms light grade cloth water chamber under described upper sealing plate 2 degree of depth, and lower shrouding 4 is octagon, has between eight rhombus vacancy sections on upper sealing plate 2 and the lower shrouding 4.Split-flow baffles 5 is 16, it is eight pipelined channels that the cloth water chamber is separated, it is eight pipelined channels that split-flow baffles 5 separates the cloth water chamber, and the transition of passage afterbody is the flat rectangular shape Water Exit head piece 6 that is provided with minute water grid 3, and a minute water grid 3 is comprised of the little grid of rhombus.The Water Exit head piece 6 of described each passage is equal to the distance of external pipeline section 1.
When current enter storage heater through water distributing tray, after current enter water distributing tray by the external pipeline section 1 that is connected with the outside, through eight pipelined channels that separated by split-flow baffles 5, evenly enter in the storage heater tank body through undue water grid 3 again; When current flowed out the storage heater tank body through water distributing tray, the water in the storage heater at first evenly entered water distributing tray by a minute water grid 3, and eight pipelined channels to the external pipeline section 1 that then separates via split-flow baffles 5 flows to external pipe.
This water-locator evenly distributes current on the whole cross section of casing, reduced turbulent region thickness and the turbulent fluctuation of main body current section, and the Water Exit head piece is flat, eliminates vertical component, and flow velocity is even, and stable water pressure is applicable to large temperature difference accumulation of heat.
