Description

Flow-harmonization device in a kind of chilled water storage system

Technical field

the invention belongs to accumulation of energy field, relate to the flow-harmonization device in a kind of chilled water storage system.

Background technology

water Cool Storage Technology utilizes electricity price between peak and valley, in the low ebb electricity price period, cold is stored in water, and the peak of power consumption period is used the cryogenic freezing water extraction storing cold for idle call by day.In the time that air-conditioning service time and non-air-conditioning service time and electrical network peak and low ebb are synchronizeed, just the idle call electric weight in electrical network rush hour can be transferred to electrical network low ebb time, use, reach the object of power cost saving.Using at present the most ripe and effective cold-storage mode is natural layering.

natural layering is thermal stratification, and thermal stratification type water cold-storage is to utilize different these physical characteristics of water density in the time of different temperatures, relies between density official post warm water and cold water and keeps separating, and avoids cold water and warm water to mix and causes loss of refrigeration capacity.

the density maximum of water in the time of 4 DEG C of left and right, along with the rising density of water temperature reduces gradually, utilizes this physical characteristic of water, makes water that temperature is low be stored in the bottom in pond, and the high water level of temperature is in the top that is stored in pond.Design good thermal stratification type water cold accumulating pond and between warm water district, top and cold water area, bottom, form a caloic exchange floor.A caloic exchange layer stable and that thickness is little is the key that improves cold-storage efficiency.

on cross section for vertical direction in cold accumulating pond, make current on whole section, flow equably reposefully and import reposefully (or drawing in by pond) in pond with gravity current or piston flow, between warm water district, top and cold water area, bottom, form and keep the caloic that effective, thickness is as far as possible little to exchange floor, key is that the top and the bottom in cold accumulating pond arrange identical sprinkler, to guarantee that current meet Fo Lei get (Frande) coefficient in the time entering cold accumulating pond, make current uniform distribution and disturbance minimally enter cold accumulating pond.The design and construction of sprinkler is the key technology of thermal stratification type water cold-storage, and we are called conventionally, the water distribution technology of water cold-storage.

water distribution technology claims again uniform flow technology, when needs carry out the pipeline circulation used time from extracting cold water in cold accumulating pond, extract by pump working, in this process, existing flow-harmonization device often just pads lastblock sponge in cold accumulating pond, by the effect of sponge, flow velocity is slowed down, but problem is, the excessive sponge depression that causes of water pump suction, and the effect that slows down flow velocity of sponge is inadequate, and current still exist maldistribution, still has upset to a certain degree, make thermoclinic length in cold accumulating pond become large, make cold consumption aggravation.

Summary of the invention

the object of the invention is for the above-mentioned problems in the prior art, flow-harmonization device in a kind of chilled water storage system is provided, flow-harmonization device outlet effect in this chilled water storage system is good, structural design is ingenious, can not cause that mesolimnion changes, solved the flow-harmonization device water outlet current maldistribution in existing chilled water storage system, flow velocity is too fast, can significantly upset mesolimnion and cause the problems such as cold consumption.

object of the present invention can realize by following technical proposal: the flow-harmonization device in a kind of chilled water storage system, described chilled water storage system comprises cold accumulating pond, it is characterized in that: described flow-harmonization device comprises cylindrical circular shell, the upper end of described shell is opening and communicates with the bottom of described cold accumulating pond, in described shell, there is rounded water board one, described water board one is connected on the inwall of described shell, on described water board one, there is sponge, described sponge mates mutually with the internal diameter of described shell, the below of described water board one has some and is the bending tube of " z " font, the port, one end of described bending tube is fixed with described water board one, the other end port of described bending tube is fixed with rounded water board two, described water board two is connected on the inwall of described shell, two ends port and the described shell inner cavity of described bending tube are conducting state, one end port that described bending tube is connected with described water board two is close mouth, in described close mouth, there is several limbers, described being " z " font bending tube by direct current portion one, kink and direct current portion two form, the two ends of described kink communicate and are connected with the end of described direct current portion one and direct current portion two, described direct current portion one is connected in described water board one, described direct current portion one and described kink form the angle that is less than or equal to 90 degree, between described water board two and described outer shell bottom wall, it is storage chamber, on described storage chamber outer wall, be connected with outlet pipe.
