Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is metal mesh structure schematic diagram of the present invention for Water curtain wall；Fig. 2 is wire netting of the present invention for Water curtain wall
Mesh enlarged diagram；Fig. 3 is the water pipe structural representation that the present invention is formed for the wire netting positive and negative of Water curtain wall.
Fig. 1, Fig. 2 and Fig. 3 are referred to, provided by the present invention for the wire netting 1 of Water curtain wall, by wire helical structure string
Connection is formed, the whole arrangement form water pipe 2 of wire helicograph.
Water curtain wall of the invention is 1 meter~50 meters with wire netting (mesh), altitude range, and width range is 1 meter~50 meters；
According to the size of required Water curtain wall, wire netting pore size is calculated by prediction equation；Water curtain wall special-purpose metal net hangs down at 90 °
In the case of straight, by calculating, water stabilization is downward, and flow speed stability is controllable.Water curtain wall special-purpose metal net is in 90 ° of vertical situations
Under, basic noiselessness, substantially without sputtering.
Wire netting of the invention has extremely strong absorption affinity to water, and stability is high, makes the even acceleration of water downward, the shape on wire netting
Into specific orderly water wave, and with tiny bubble, water velocity is different, and lines is also presented various change.It is uniform and stable
Current covering wire netting on, just like one side flowing wall.
In addition to above attribute, wire netting is also equipped with two characteristics：
One, coordinates light
Metal net surface is bright and colourful, and stereovision is clearly demarcated, and third dimension is full, and regular movements effect is more obvious.
Two, coordinate shadow casting technique
Wire netting can do projection screen, and picture is clear, and color resolution is high, can replace electron tube screen.
Metal reticular density measuring and calculating for Water curtain wall of the invention is as follows：
M1:The quality that mesh is measured in water；M2:The quality of mesh is measured in atmosphere；V:The volume of water；lL：Water it is close
Degree.
Can be calculated by formula after above constant is measured
M1-M2=VlL
The volume of Mesh can be just immersed in the liquid of known density by by mesh, the method by determining its quality
To try to achieve.
In engineering survey, the principle formula during density of mesh can be determined with weighing method.
L=(M1lL)÷(M1-M2)
As long as measuring relevant amount and bringing into wherein, it is possible to calculate the density of mesh.
In mesh researchs, porosity, the measure of water absorption rate is the best method examined and determine water curtain quality.Mesh's
Porosity, water absorption rate are the marks of the architectural feature of mesh.
Water absorption rate：Vertical fixed mesh, water from above along mesh from top to bottom direct currents, in the temperature and time of regulation
Water suction the ratio between quality and the mesh proper mass without flowing water.
Therefore, water absorption rate is directly proportional to open-drain hole, is often reacted using water absorption rate in research and produce reality
The pore size of mesh.
The density of Mesh can be divided into bulk density and real density.
Bulk density：The ratio between the quality of the mesh without free water and the cumulative volume of mesh；Real density：Bulk density is removed
Volume shared by whole holes.
The porosity of Mesh, the calculating of water absorption rate is all based on the measure of density, and the measure of density is then based on A Ji meter
Moral law, from Archimedes' principle, any object in immersion liquid is subjected to the effect of the static pressure of liquid, pressure
Size be equal to mesh nets and arrange the weight of water.Weight is a kind of gravity value, therefore Archimedes' principle can be represented by the formula：
Volume lb=g/cm3Density：Press calculating.
lB=lW×M0/(M1-M2)
M0：The dry aerial quality l of meshT=lW×M'0/(M'1+M'0-M'2)
M1：Mesh nets aerial quality under water flowing full state
M2：Quality of the mesh nets in water
lW：In the density of normal-temperature water during experiment
Real density lTIt is calculated as follows
lT=lW×M'0/(M'1+M'0-M'2)
M'0：Aerial quality when Stainless steel 316 is dried
M'1：Mounted in the quality of the density bottle of distilled water
M'2：The quality of the density bottle that Stainless steel 316 powder sample adds water
lW：The density of warm water at the trial
Bulk density and density of the porosity according to obtained by measure, porosity la are calculated as follows：
la=(1-lb/lt) × 100%
lb：Mesh bulk densities；lt：The density of mesh.
Water absorption rate：Water absorption rate WaIt is calculated as follows
Wa=(M1-M0)/M0× 100%
M0：Dry mesh nets aerial quality；M1：Water saturation flowing is in the online aerial quality of mesh.
Specific surface area method of testing：It is main to have water in mesh nets continuous flow method and dry net static volumetric method.
Wire netting application for Water curtain wall of the invention is as follows：The order mesoporous model of reference that water curtain passes through different phase
Mesh, make mesh that there is larger specific surface area.With respect to large aperture and regular pore passage structure, the stream of water can be processed
Speed, is good shape-selective catalyst.Particularly during streamflow is increased, order mesoporous mesh make use of to show
Different water wave forms.
Suction-operated control range can be regulated and controled by the size in aperture, and possessing to be desorbed rapidly, the feature of recycling.Make
It has good environmental protection and economy benefit.
Application of the order mesoporous model on water curtain mesh, makes water curtain be provided with high specific surface area.Orderly duct knot
The characteristics of structure has regular, pore size is continuously adjustable.
The density 1g/cm of water3, 10^3 kilograms per cubic meter
Water calculates as follows in mesh surface tension：
F=α L
α:Water surface tension coefficient；L：Length
F=α π (D1+D2)
D1：Internal diameter；D2：External diameter.
Water is in mesh flow rate calculations
Open channel uniform flow amount：Q=A × C (R × J)∧(1/2)
Q:Flow, A:Flow area, C:Thank ability coefficient, R：Net open channel radius, J:The gradient of net
The speed V and flow Q of water can thus be calculated.
Although the present invention is disclosed as above with preferred embodiment, so it is not limited to the present invention, any this area skill
Art personnel, without departing from the spirit and scope of the present invention, when a little modification and perfect, therefore protection model of the invention can be made
Enclose when by being defined that claims are defined.
