Description

Technical Field

[0001] The utility model belongs to the technical field of cooling tower fillers, and in particular relates to a frustum-shaped adhesive point oblique folded wave cross-flow type cooling tower filler sheet. Background Art

[0002] A cooling tower uses water as a circulating coolant, absorbing heat from the system and releasing it into the atmosphere to lower the water temperature. Cooling towers can be categorized by the direction of water and air flow: 1. Counterflow cooling towers; 2. Crossflow (DC / AC) cooling towers; and 3. Mixed flow cooling towers.

[0003] Cooling tower filler is a device that cools the cooling water in the cooling tower. A cross-flow cooling tower is a device that uses forced ventilation from a ventilator to allow air to flow horizontally into the tower, while water droplets flow from top to bottom in the filler with the help of gravity. The flow directions of the two fluids form a 90° angle, and mass and heat transfer occurs in the filler.

[0004] The cooling tower fill is the most important part of the cooling tower. Its efficiency depends on the degree of contact between the cooling water and the air in the fill. Cooling tower fill is usually formed by bonding multiple cooling filler sheets together. Existing filler sheets have some defects in terms of surface area and drainage time. The degree of contact is low and uneven, resulting in poor cooling effect of the cooling tower. Utility Model Content

[0005] In response to the above problems, the utility model provides a frustum-shaped adhesive point oblique folded wave cross-flow cooling tower filler sheet to solve the technical problem that the degree of sufficient contact between cooling water and air is low and the contact is uneven, resulting in poor cooling effect of the cooling tower.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A truncated cone-shaped bonding point oblique wave cross-flow cooling tower filler, comprising a water inlet unit, a water outlet unit, an air inlet unit, an air outlet unit and a flow channel unit, wherein the water inlet unit and the water outlet unit are respectively arranged on the upper and lower sides of the cooling tower filler, and the air inlet unit and the air outlet unit are respectively arranged on the left and right sides of the cooling tower filler, and the flow channel unit is a plurality of oblique wave stagnant flow troughs arranged in sequence, and the direction of each flow channel of the oblique wave stagnant flow trough is inclined downward, and the flow channel unit comprises an oblique wave peak flow channel unit and an oblique wave trough flow channel unit which are arranged horizontally from top to bottom, and the oblique wave peak flow channel unit and the oblique wave trough flow channel unit connect the air inlet unit and the air outlet unit on both sides; a truncated cone-shaped bonding point structure is also provided on the flow channel unit.

[0008] Furthermore, the truncated cone-shaped bonding point structure includes alternately arranged concave point structures and convex point structures.

[0009] Furthermore, the inlet end of the water inlet unit and the outlet end of the water outlet unit are both provided with a flow channel opening with a trapezoidal cross section, and the flow channel openings of the water inlet unit and the water outlet unit are both vertically arranged.

[0010] Furthermore, the air inlet end of the air inlet unit and the air outlet end of the air outlet unit are both provided with a flow passage opening with a trapezoidal cross section, and the flow passage openings of the air inlet unit and the air outlet unit are both inclined.

[0011] Furthermore, the oblique wave crest flow channel units and the oblique wave trough flow channel units in the flow channel units are alternately arranged with crests and troughs from top to bottom, and the concave point structures and convex point structures are both arranged at the trough positions of the oblique wave trough flow channel units.

[0012] Furthermore, a hanging hole is preset on the flow channel unit.

[0013] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0014] (1) The independently designed oblique wave filler flow channel increases the cooling surface area per unit volume by evenly adding several oblique wave stagnation grooves on the cooling wave; the contact surface area between the water film and the filler is further increased by the design of the wave-shaped connecting edge and the stepped connecting side. This slows down the water film's downward flow, prolongs the heat and mass exchange time, and improves the cooling effect;

[0015] (2) The truncated cone bonding point structure is independently designed. A truncated cone bonding structure is provided in the filler sheet unit, which effectively avoids the misalignment of the bonded filler sheet units during the working process, so that the filler sheet units can be firmly bonded.

[0016] (3) The stagnation wave structure of the packing sheet of the utility model is a vertical convex stagnation wave. By adding the vertical convex stagnation wave and coordinating it with the main fold wave, the speed of the water film discharge is slowed down, the heat and mass exchange time is extended, and the cooling effect is improved.

[0021] Preferably, the inlet end of the water inlet unit 1 and the outlet end of the water outlet unit 2 are both provided with a flow channel opening with a trapezoidal cross section, and the flow channel openings of the water inlet unit 1 and the water outlet unit 2 are both arranged vertically. The water inlet unit 1 and the water outlet unit 2 are both arranged at equal intervals to achieve uniform water distribution and water outlet.

[0022] The air inlet end of the air inlet unit 3 and the air outlet end of the air outlet unit 4 are both provided with a flow passage opening with a trapezoidal cross section, and the flow passage openings of the air inlet unit 3 and the air outlet unit 4 are both inclined.

[0023] The flow channel unit 5 of the present invention is a plurality of oblique wave stagnant wave grooves arranged in sequence; the oblique wave peak flow channel unit 51 and the oblique wave trough flow channel unit 52 in the flow channel unit 5 are alternately arranged with peaks and troughs from top to bottom, further slowing down the flow velocity of water when passing through, increasing the water spraying resistance, and increasing the cooling effect.

[0024] The concave and convex structures 6 and 7 are both located at the troughs of the oblique wave trough flow channel unit 52. The front and back of the packing sheet are provided with non-planar surfaces shaped like concave and convex points. The front and back of the packing sheet are provided with a plurality of arrays of convex and concave structures 7 and alternating concave and convex structures 6. The convex structures 7 on the front of the packing sheet also form concave structures 6 on the back. When the water flows, the concave and convex structures further increase the water flow resistance and improve cooling efficiency. Furthermore, the structures cooperate with each other to enhance the firmness of the installation.

[0025] The flow channel unit 5 is also provided with a hanging hole 8 to facilitate the installation of the filler sheet.

[0026] When the utility model is in use, multiple filler sheets are cross-stacked, and the two water inlet ports and the two water outlet ports on two adjacent filler sheets are superimposed to form a honeycomb flow channel opening. The two groups of cross-stacked flow channel units form an internal cooling flow channel. High-temperature water flows in from the upper water inlet flow channel, and the cooling gas is forced to flow in horizontally under the action of the ventilator's forced ventilation. The water and gas are fully mixed in the cooling flow channel to exchange heat, thereby achieving cooling of the high-temperature water.

[0027] The adjacent filler sheet bodies of the utility model cooperate with each other and can be detachably connected, thereby improving the stability between the two adjacent filler bodies, facilitating the disassembly and installation of the filler sheet bodies, and conveniently cleaning the filler sheet bodies, thereby improving the cooling efficiency of the cooling tower for cooling water.
