Abstract

The utility model relates to a wet curtain whose wet curtain plate is wavy-shaped. The surface of the wet curtain plate is covered with one layer of hydrophilic coating layer and also provided with many holes. The waviness directions of the wet curtain plate are mutually crossed and folded, the both sides of the wet curtain plate are provided with lateral plates, the upper part of the wet curtain plate is provided with a crown plate, the lower part of the wet curtain plate is provided with a soleplate, and the lateral plates are tensed by tension fixed rods. The utility model has the advantages of good dimensional stability, good fungus resistance and weather resistance properties, convenient cleanness of jamming foreign matters and higher service life. The utility model is suitable for cooling and conditioning of high temperature workshops.

Description

Wet curtain

The utility model relates to a kind of wet curtain, also is the critical piece of wet curtain blower fan cooling system, belongs to the technical field of cooling, humidity control device.

At present wet curtain blower fan cooling system has been widely used in agricultural, high-temperature workshop spinnery and the place that needs cooling adjustment humidity.Agriculturally usually be applied to the greenhouse, the cooling of livestock and poultry house aspect has all obtained good effect.Wet curtain mainly adopts speciality polymer material and wood pulp fiber molecule space crosslinked, and forms with high water-fast strong weather resisteant material gluing, guarantees that it has enough wet deflections, and high-hydroscopicity can have big evaporite ratio surface area and lower overcurrent drag losses again.The paper fiber of this wet curtain is through being pressed into corrugated, and it is bonding to stick with glue agent then.When it utilizes the water evaporation airborne sensible heat is changed into latent heat, though its cooling-down effect is good, but its shortcoming is: poor dimensional stability, anti-thunder mould, weather resisteant energy inequality, and use a period of time just stopping state can take place, can not clean.The wet curtain of this kind fiber is shorter service life, generally have only 4 to 5 years, and cost is high slightly, demands further improvement urgently.

The purpose of this utility model is that a kind of wet curtain will be provided, and it can overcome above-mentioned shortcoming.

The purpose of this utility model is to realize like this, utilize plastic sheet to be pressed into corrugated curtain sheet through the corrugation machine, make the surface form a water thin film layer with special process again, it is combined then several pieces to be overlapped each other, every ripple direction is a juxtaposition, bonding without viscose glue, directly be pressed into one, there is side plate both sides, there is top board the upper end, base plate is arranged at the bottom, with the bar tension that is strained and fixed, just constitutes the wet curtain that is suitable between the side plate.

Fig. 1 is the wet curtain sheet schematic diagram.

Fig. 2 is wet curtain sheet combination schematic diagram.

Fig. 3 is wet curtain structure figure.

Now in conjunction with the accompanying drawings the structure of wet curtain is described in detail.

By Fig. 1, wet curtain sheet 1 is with hydrophilic plastics plate, and the process corrugation forming machine is pressed into corrugated, uses special technology (having patent to illustrate the technology content in addition) to cover one deck rete 2 again, and there is micropore 3 on wet curtain sheet 1 surface.

Fig. 2 is the constitutional diagram of wet curtain sheet.

Wet curtain sheet 1 is can multi-disc superimposed, generally can be made up of 20-5000 layer curtain sheet, but wet curtain commonly used is formed by the 200-400 sheet is superimposed, when superimposed, the ripple direction is interlocked, and strong hydrophilic radical 2 has all been introduced on every surface makes frosting alligatoring, high-energy ray irradiation.

Fig. 3 is wet curtain structure schematic diagram.

Superimposed multilayer wet curtain sheet 1, there is side plate 4 both sides, and top board 5 is arranged at top, and base plate 6 is arranged at the bottom, and is fixing with the bar 7 that is strained and fixed between the side plate 4.

When water when stream is drenched at wet curtain top downwards, under the self gravitation effect of water, motion is from the top down flowed along curtain sheet ripple direction again on the other hand on the one hand.Because curtain chip surface has micropore to exist, make flowing of water more unordered, it is also more even to distribute.When air during by wet curtain, nonsaturated air produces the equal-enthalpy humidifying process with wet curtain surface, and water evaporates is drawn a large amount of latent heat, forces to drop to the wet-bulb temperature that is bordering on the air before entering the curtain that wets through wet curtain air in bulb temperature.Because the wet curtain sheet that has adopted plastics to make change has structurally been arranged, thereby the disengagement area of unit volume is higher by about 10% than wet curtain made of paper, so cooling-down effect is more good.

Compared with prior art, this wet curtain has following advantages.

1, service life is higher.

2, dimensional stability is good.

3, weather resisteant, fungus resistance are all better.

4, be convenient to clean the obstruction foreign material.

5, processing is easy.
