Detailed Description
The invention will be described in further detail below with reference to the drawings and specific examples. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Parts which are not described in the invention can be realized by adopting or referring to the prior art.
As shown in fig. 1, a first aspect of the present invention provides a wet curtain liquid distributor, which includes an inflow pipe 1, a liquid distribution tank 3 and a water outlet 6 located at the bottom of the liquid distribution tank 3, wherein a flow dividing plate 4 is disposed in the liquid distribution tank 3 along the length direction of the liquid distribution tank 3, the liquid distribution tank 3 is divided into an upper first-stage liquid distribution tank 31 and a lower second-stage liquid distribution tank 32 by the flow dividing plate 4, and after the first-stage liquid distribution tank 31 is filled with water, the water flows through the flow dividing plate 4 and overflows into the second-stage liquid distribution tank 32.
According to the wet curtain liquid distributor, the liquid distribution groove is provided with the secondary water distribution flow channel, the height of the flow distribution plate is utilized to store water in the primary liquid distribution groove, so that kinetic energy with uneven distribution of the drained water is converted into stored water potential energy, then when the stored water height exceeds the flow distribution plate, the potential energy is converted into kinetic energy with relatively even transverse distribution and overflows into the secondary liquid distribution groove, and therefore the uniformity of the drained water at the beginning of the secondary liquid distribution groove is improved, the problem that the drained water is uneven when the transverse span of the existing liquid distributor scheme is large can be effectively solved, the phenomena of water film hole blocking, liquid level adhesion and the like of the liquid distribution holes due to liquid surface tension can be improved, the overall water distribution uniformity of the liquid distributor is improved, and the overall humidifying capacity of a humidifying system is improved.
In a preferred embodiment, as shown in fig. 1 and fig. 2, the upper surface of the liquid distribution tank 3 is an open structure, the inflow pipeline 1 with an inner diameter D is arranged above the primary liquid distribution tank 31, the lower pipe opening of the inflow pipeline extends to the open interior of the liquid distribution tank 3, and the rectifier 2 for pressure relief and diversion is arranged in the primary liquid distribution tank 31 just below the inflow pipeline 1. The water flowing out of the inflow pipe 1 first flows through the rectifier 2 to be decompressed and divided, and then flows into the primary liquid distribution tank 31.
In other embodiments, the upper surface of the liquid distribution tank 3 may also be of a non-open structure.
In a more preferred embodiment, as shown in fig. 2 and 3, the rectifier 2 is formed in its axial direction as two sections of circular arc surfaces, the first section having a diameter D1 and the second section having a diameter D2, and the 0-and-D1-and-D-bundles D2. The arrangement can reduce the local water pressure of the sewer position, prevent the phenomenon of splashing caused by the fact that inflow of the sewer directly impacts the bottom surface of the liquid distribution groove, and meanwhile, the wall attachment effect of the flow field at the sewer can be enhanced by the two sections of arc surfaces, so that the inflow stroke is delayed, the flow velocity of the inflow can be effectively reduced by the two sections of unloading, and the rectification purpose is achieved.
In a more preferred embodiment, the rectifier 2 is provided with a plurality of rectifying plates 23, and the rectifying plates 23 are circumferentially distributed along the circumference of the rectifier 2. The multiple circumferentially distributed rectifying plates are arranged, so that the inflow direction can be drained in multiple directions all around, the local water pressure of the water drainage position is further reduced, and the rectifying effect of the rectifier is improved.
In a preferred embodiment, the bottom surface of the primary liquid distribution groove 31 is provided with a downward slope in the direction extending from the middle position to both sides, and the slope surface forms an included angle α with the horizontal plane, preferably, 0< α <5 °. More preferably, the liquid distribution bottom surface 311 of the primary liquid distribution groove may be a slope plane, and may also be a circular arc transition surface.
The liquid distribution uniformity of the first-stage liquid distribution groove can be improved by arranging the first-stage liquid distribution groove into an inclined surface structure, the liquid flow momentum at the lower water position is maximum, the flow velocity is highest, and in the process of distributing liquid to two sides, the momentum loss causes the flow velocity to be reduced, so that the liquid level at the position right opposite to the lower water opening is higher than the liquid levels at the two sides, and the liquid level overflows into the lower-stage liquid groove in advance, thereby affecting the final liquid distribution effect; the inclined plane structure can utilize potential energy generated by liquid level difference to improve liquid distribution kinetic energy in the process of shunting at two sides and improve the flow velocity of water distributed to two sides, so that the heights of the liquid levels in the middle of the first-stage liquid distribution tank and the two sides are kept consistent, and the liquid distribution uniformity is improved.
As shown in fig. 2, the radial width of the water level in the primary cloth tank 31 is L, and the radial width in the extending direction on both sides is L1, then 1/3 is constructed by L1/L <1. Therefore, on one hand, the high growth rate of the liquid in the lower water position can be delayed, the width of the lower water position is larger than the width of the liquid distribution on two sides, and the water pressure for distributing the liquid to the two sides can be increased, so that the flow speed of the liquid distribution on the two sides is increased, and the liquid distribution uniformity of the first-stage liquid distribution groove is further improved; on the other hand, the liquid distribution widths on the two sides are reduced, and the volume of the first-stage liquid distribution groove can be reduced to a certain extent, so that a circulating water pump with smaller flow can be selected, and the product development cost is saved.
In the embodiment of the present invention, the water outlet holes 6 are disposed at the bottom of the secondary liquid distribution tank 32, wherein the distance between adjacent water outlet holes 6 is a, and a is greater than or equal to 10mm. The distance between adjacent water outlets depends on the density distribution of the wet curtain ripples, the optimal humidification effect can be achieved by corresponding to the distribution distance of the wet curtain ripples, on one hand, the distance between the adjacent water outlets is not too small, the pressure at the position is relatively small due to the fact that the relative flow rate of the position of the water outlet is large, tension exists between liquid, the too small distance can be influenced by the pressure and the tension at two sides, liquid level adhesion occurs at the water outlet position, and therefore local water drainage uniformity is influenced.
In a preferred embodiment, as shown in fig. 4, the dividing plate 4 is provided with inverted triangular overflow ports 41, a vertically arranged partition 322 is arranged between every two adjacent inverted triangular overflow ports 41, the upper edge of the partition 322 is located at a height level with the upper edge of the dividing plate 4, and the lower edge is arranged at the bottom of the secondary liquid distribution groove 32. The overflow ports 41 and the water outlet holes 6 can be in one-to-one correspondence or a single overflow port corresponds to a plurality of water outlet holes.
Because the water is influenced by the self-tension, liquid film adhesion is easily formed, if no overflow port structure exists, the positions of the lower water of the flow distribution plate are influenced by adhesion of the attached wall, and the flow balance of the positions of the lower water holes cannot be ensured; the overflow port of the flow distribution plate is preferably in a triangular structure, so that the generation of liquid film by liquid surface tension can be inhibited, but the flow distribution plate is not limited to a triangular scheme, and similar structures such as U-shaped, trapezoid and square can be selected; in addition, the action range of a single overflow port of the flow distribution plate is not limited to one sewer opening, and the liquid distribution effect gradually deteriorates along with the increase of the number of water outlet holes.
In a preferred embodiment, as shown in fig. 4 and 6, the relative height of the lower vertex O of the overflow port 41 from the distribution bottom surface 311 of the primary distribution tank is h, and according to the actual drainage situation, the relative height of the lower vertex O of the overflow port 41 from the distribution bottom surface of the primary distribution tank can be adjusted to h1, and | h-h1 | ≦ 4mm. This means that the relative height of each overflow opening is not fixed, and the position can be finely adjusted according to the actual launching situation, but the adjustment size is not too large based on the high sensitivity of the waterway, so that the adjustment range is limited, and the best is | h-h1 | ≦ 4mm.
In a more preferred embodiment the overflow 41, preferably the lower apex O of the triangular overflow, is at a relative distance H from the upper edge of the splitter plate 4, and H ≧ 3mm. The overflow mouth is apart from splitter plate top edge relative distance, also is the vertical upward span of overflow mouth, because of there is tension and attaches the flowing characteristic of wall by water self, if the overflow mouth height is low excessively can lead to adjacent position to glue and flow in a department to make the individual hole site flow step down.
As shown in fig. 4, the overflow column 5 is further disposed upward at the bottom of the secondary liquid distribution groove 32, an overflow hole is disposed inside the overflow column 5, and the upper end surface of the overflow column 5 is lower than the height of the entire sidewall of the liquid distribution groove 3 and higher than the upper end surface of the flow distribution plate 4, so as to prevent the overflow phenomenon that the liquid level exceeds the upper edge of the sidewall of the liquid distribution groove due to the lower flow rate of the liquid distribution groove being lower than the water injection flow rate when the lower flow rate is too large.
In a preferred embodiment, as shown in fig. 4 and 5, the water outlet holes 6 at the bottom of the secondary liquid distribution tank 32 can be a straight hole structure with uniform size from top to bottom, or a conical structure with a cross section converging from top to bottom, and the taper angle β of the conical structure is 0 ° ≦ β ≦ 15 °. The straight hole structure can also play a role in launching water, but the conical hole is more favorable for the launching trend, thereby avoiding the phenomenon of hole blockage caused by tension.
More preferably, the minimum side length of the cross section of the water outlet 6 is c, and c is more than or equal to 1mm. When the size is too small, a liquid film is more likely to form at the lower water outlet, and the hole is blocked, so that c is preferably not less than 1mm.
More preferably, the water outlet hole 6 extends out of the lower bottom surface of the liquid distribution groove 3, the extending length b is more than or equal to 1mm, the lower surface of the water outlet hole is of a beveling structure, and a relative angle theta is formed between the beveling surface and the lower bottom surface of the liquid distribution groove. Because the fluid has the wall attachment flowing phenomenon, if the hole positions are flush with the lower surface, water flow flows towards two sides along the lower surface of the liquid distribution groove, so that water adhesion with adjacent hole positions occurs, and the local water drainage is not uniform; in addition, the lower water gap is beveled, so that the flowing trend of the lower water gap along the beveled long wall side can be enhanced to vertically flow downwards, and the problem of uneven water distribution caused by hole blocking by tension and liquid level adhesion is effectively solved.
As shown in fig. 7, the drainage uniformity of the wet curtain liquid distributor of the present application is significantly improved compared to the liquid distributor of the prior art.
In a second aspect, the invention provides an evaporative cooling apparatus comprising the above-described wet curtain applicator. Therefore, all the advantages or benefits of the wet curtain liquid distributor are also achieved.
