Description

Technical Field

[0001] The utility model belongs to the technical field of cooling equipment, and specifically relates to an industrial water curtain type cooling tower. Background Art

[0002] Cooling towers use water as a circulating coolant. The glass fiber reinforced plastic cooling tower is widely used in the current industry. The interior of this type of cooling tower is basically equipped with serpentine pipes. Hot water is sprinkled from the top to the serpentine pipes for cooling. Due to the high height and dense arrangement of the serpentine pipes, the sprinkled hot water is difficult to fully contact the bottom of the serpentine pipes, and the cooling effect is not satisfactory. In addition, the impurities brought out by the hot water will further adhere to the surface of the serpentine pipes, thereby seriously affecting the cooling of the hot water by the serpentine pipes. In view of this, this case was born. Summary of the invention

[0003] The utility model aims to provide a water curtain type cooling tower with compact structure design and good circulating water cooling effect in view of the deficiencies of the prior art.

[0005] The water purification device comprises a vertical filter plate vertically arranged at the bottom of a tower shell and a horizontal cover plate covered on the top surface of the vertical filter plate.

[0006] The surface of the vertical filter plate is divided into two parts: a filterable surface and a common partition surface. The vertical filter plate divides the inner bottom of the tower shell into two independent areas.

[0007] The four sides of the horizontal cover plate are tightly attached to the four sides of the inner wall of the tower shell, and the bottom of the horizontal cover plate is tightly attached to the top surface of the vertical filter plate. A water hole is arranged on a part of the surface of the horizontal cover plate, and the horizontal cover plate is installed tilted as a whole to facilitate the water on the surface of the horizontal cover plate to flow into the water hole.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] The utility model cooling tower is mainly aimed at improving the defects of the current industrial cooling tower which adopts coils to spray cooling water, which has unsatisfactory cooling and easily produces impurities attached on the surface of the coils.

[0018] like Figures 1 to 4 As shown, a new type of water curtain cooling tower is composed of a closed tower shell 1, the tower shell 1 is square or round, and the hot and cold water exchange is carried out inside the tower shell 1; the cooling tower is usually placed outdoors, so the environment is very harsh, and the cooling tower and the indoor working machine are always working in conjunction; a cooling fan 2 is arranged on the top surface of the tower shell 1, and a louver plate and a dustproof net 3 are arranged on the outer wall of one side of the tower shell 1 to ensure the air flow in the cooling tower; the inner surfaces of the other side walls of the tower shell 1 are all provided with water curtains 9, the water curtains 9 are composed of ordinary planes, and are respectively attached to the inner wall surfaces of the tower shell 1, and are mainly used for cooling after hot water is sprinkled on the surface of the water curtains, and the inner bottom of the tower shell 1 is provided with a vertical filter plate 8 and a horizontal cover plate 7 covered on the top surface of the vertical filter plate 8, the horizontal cover plate 7 plays a role of dust prevention on the one hand, and facilitates the water on the water curtain 9 to flow to the horizontal cover plate 7 on the other hand.

[0019] The surface of the vertical filter plate 8 is divided into two parts: a filterable surface 801 and a common partition surface 802. The vertical filter plate 8 divides the inner bottom of the tower shell 1 into two independent areas, namely area A and area B.

[0020] The four sides of the transverse cover plate 7 are tightly attached to the four sides of the inner wall of the tower shell 1, and the lower bottom of the transverse cover plate 7 is tightly attached to the top surface of the vertical filter plate 8. A part of the surface of the transverse cover plate 7 is provided with a water hole 701, and the other part is a common panel 702, and the transverse cover plate 7 is installed as a whole at an angle, so that when the water on the surface of the water curtain 9 flows into the transverse cover plate 7, the water on the surface of the transverse cover plate 7 can quickly flow into the water hole 701. When the transverse cover plate 7 is covered on the top surface of the vertical filter plate 8, the surface of the water hole 701 is just opposite to the A area, and the surface of the common panel 702 is just opposite to the B area. Therefore, the water flowing onto the top of the transverse cover plate 7 all flows into the A area.

[0021] The lower end surface of the tower shell is provided with a water inlet 10 and a water outlet 11, and the water inlet 10 is provided outside the A area, while the water outlet 11 is provided outside the B area. The water inlet 10 is connected to the water inlet pipe, and the water outlet 11 is connected to the water outlet pipe, and the water outlet pipe is connected to the Y-type filter 6 and the water pump 5, respectively, and the Y-type filter 6 is further connected to the indoor unit through an external pipe. The water inlet pipe connected to the water inlet 10 is directly connected to the hot water drain pipe of the indoor unit, so the water flowing into the water inlet is the hot water discharged from the indoor unit, and the hot water is subjected to cold and heat exchange in the cooling tower.

[0022] The specific process of hot and cold water exchange in the cooling tower of the utility model is as follows: after the indoor unit is started, the indoor unit and the cooling tower work at the same time (such as indoor air conditioning), and the water pump 5 works. After the indoor unit has been running for a period of time, the dynamic hot water generated by the indoor unit is sprayed from the water inlet 10 onto the water curtain 9 arranged on the inner wall of the tower shell. After a steady stream of hot water is sprayed on the water curtain 9, the water on the water curtain 9 flows uniformly onto the surface of the dust cover plate 7. Since the dust cover plate 7 is installed in an inclined manner, the water flows into the water hole 701 and further uniformly flows into the A area for preliminary impurity precipitation. When the water in the A area is precipitated to a certain height, such as overflowing the boundary between the ordinary partition surface 802 and the filter surface 801 on the vertical filter plate 8, the water in the A area can be filtered into the B area through the filter surface 801; and the cooling water after filtration is pumped into the Y-type filter under the action of the water pump 5 and further flows into the indoor unit for cooling, thereby achieving the purpose of water circulation.
