Description
Technical field
The present invention relates to a kind of technology that effectively can reduce water distribution mouth flow velocity for natural layering method water cold storage, specifically a kind of diffusing device.
Background technology
Natural layering technology is applied in chilled water storage system more and more, and the key of this technology is effective water distribution system reasonable in design, to reduce mesolimnion thickness, improves cold-storage efficiency.Although the more employing of current existing water distribution system repeatedly water distribution coordinate the mode of all kinds of Novel cloth hydrophone, but for the chilled water storage system compared with large discharge, still fail generally to obtain good mesolimnion effect, mainly due to these water distribution methods, to fail the flow control of water distribution mouth enough low for this.
And the design quality of water distribution system depends primarily on hydraulic characteristic parameter Fleder number (Fr) relevant to mesolimnion and water distribution mouth Reynolds number.Owing to only having when Fr≤1, in import current, buoyancy is greater than inertia force, can form good gravity current, i.e. the mixing phenomena of hot and cold water not obvious, and the principle of therefore general design can make Fr≤1, according to Fr formula: Fr=q/ (gh
i 3(ρ
i-ρ
n)/ρ
n)
0.5, wherein q is the volume flow (m of water-locator unit length
3/ m ﹒ s), and q=Q/L, Q are the maximum stream flow (m by water-locator
3/ h), L is the effective length (m) of water-locator; G is acceleration of gravity; Hi is the minimum inlet height (m) of water-locator; ρ
ifor import water density (kg/m
3); ρ
nfor ambient water density (kg/m
3).And determining that another important parameter of mesolimnion thickness is water distribution mouth Re number, Re is q and the ratio of the kinematic viscosity of water.To sum up can find, flow is larger, Fr number and intake-outlet Re larger, by improving water distribution length L, to reduce the volume flow q of unit length water, thus lower water distribution mouth flow velocity can only be realized, to reduce hot and cold water mixing.
Summary of the invention
The object of the present invention is to provide a kind of diffusing device, can increase the water distribution length of water-locator further, reduce the flow velocity of water distribution mouth, compression mesolimnion thickness, improves the diffusing device of cold-storage efficiency.It can be installed on the water distribution pipe of multiple water-locator (octagon water-locator, linear pattern water-locator etc.), is connected with its water distributing pore, and its structure is simple, not easily blocks, effectively can increase water distribution length, reduces water distribution mouth flow velocity.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of diffusing device, this diffusing device is installed on water distribution pipe, it is characterized in that, this diffusing device includes ozzle and diffusing body, ozzle is connected with the water distributing pore on described water distribution pipe, described diffusing body includes skin, internal layer, skin is fixedly connected with draw-in groove by the joint pin cooperatively interacted with between internal layer, described diffusing body is divided into two sections, one section is land portions, one section for circular radial card part, described ozzle is connected with outer field land portions, and fluid carries out diffusing by ozzle from the gap of the inside and outside layer of diffusing body.
Described diffusing volume surrounding is hat shape, and the axes coincide of the axis of ozzle and diffusing body.
Described diffusing volume surrounding disc face sections inner side is provided with 4 joint pins uniformly, and the relevant position of diffusing body internal layer and outer joint pin is provided with 4 draw-in grooves.
Fluid enters diffusing body internal layer by ozzle, first by one section of sphere, then by one section of radial disc face, thus realizes rectification and reduces the object of flow velocity.
The sphere of diffusing body internal layer, utilize wall attachment effect to reduce flow velocity, namely fluid leaves original flow direction, changes the material flows protruded with work into, and between fluid and its body surface of flowing through, there is face when rubbing, the flow velocity of fluid can slow down.
Fluid flows between the disc face of inside and outside layer by internal layer sphere, both rectifiables, can increase water distribution length further again on the basis flowing through the preceding paragraph sphere, thus makes the exit velocity of fluid be able to obvious reduction.
Fluid carries out diffusing by the gap of the inside and outside layer of diffusing body, has stronger scouring capability, therefore largely can reduce the possibility of fouling to internal layer surface.
The present invention makes fluid enter diffusing body internal layer by ozzle, first by one section of sphere, then by one section of radial disc face, thus realizes rectification and reduces the object of flow velocity.Fluid is mainly made to leave original flow direction by sphere, change the material flows protruded with work into, face is there is when rubbing between fluid and its body surface of flowing through, the flow velocity of fluid can slow down, and fluid flows between the disc face of inside and outside layer again by internal layer sphere, namely be similar to the principle of circular radial dish-type water-locator, i.e. rectifiable, on the basis flowing through the preceding paragraph sphere, increase water distribution length further again.Namely be the change due to this device traffic channel, enhance linear flow, thus whole water distribution system increases diffusing length on the basis of previous stage water distribution.
Advantage of the present invention is: install this device at the end of all kinds of water distribution system, water distribution length can significantly be increased, and have passed sphere and circular radial card due to fluid, make the exit velocity of fluid be able to obvious reduction, and also help water distribution uniformity; In addition, because fluid is the gap by the inside and outside layer of diffusing body, there is stronger scouring capability to internal layer surface, therefore largely can reduce the possibility of fouling.
