Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, specifically an openable / closed cooling tower. Background Technology

[0002] Cooling of circulating water is the result of three processes: evaporative cooling, contact cooling, and radiative cooling, all occurring through contact between water and air. Evaporative cooling occurs when water forms droplets or a very thin film of varying sizes within the cooling system, increasing the contact area and duration with the air, thus enhancing evaporation and allowing the water vapor to carry away the heat required for vaporization, thereby cooling the water. Contact cooling occurs when water comes into contact with cooler air; the temperature difference allows heat from the hot water to be transferred to the air, lowering the water temperature. Radiative cooling is a phenomenon where heat energy is transferred in the form of electromagnetic waves without the need for a heat transfer medium.

[0003] During the existing cooling water circulation process, due to the long-term operation of the cooling tower, a large amount of heat accumulates in the packing module, which is composed of multiple stacked corrugated packing sheets. As a result, the temperature of the densely arranged corrugated packing sheets in the packing module gradually increases, and the higher temperature of the corrugated packing sheets greatly reduces the heat exchange efficiency of the cooling water. Summary of the Invention

[0004] The purpose of this invention is to provide a packing-type air-guided cooling tower with high heat exchange efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A packed air-guided cooling tower includes a packed module comprising multiple stacked corrugated packing sheets, each corrugated packing sheet being formed by connecting multiple packing sheet units. Each packing sheet unit includes an upper packing section, a lower packing section, and an air-guided pipe. The upper and lower packing sections are respectively provided with an upper airflow chamber and a lower airflow chamber. The lower surfaces of the upper and lower packing sections are respectively provided with multiple spaced-apart upper air jets and multiple spaced-apart lower air jets, which communicate with the upper and lower airflow chambers, respectively. The lower end of the upper packing section is connected to the upper surface of the air-guided pipe, and the upper end of the lower packing section is connected to the lower surface of the air-guided pipe. Both the upper and lower airflow chambers of the upper and lower packing sections are connected to the air-guided pipe, and the upper and lower packing sections form a horizontal V-shaped structure.

[0006] Furthermore, the end of the lower packing section in the packing unit is connected to the end of the upper packing section in the adjacent packing unit, and the lower airflow cavity in the lower packing section of the packing unit is not connected to the upper airflow cavity in the upper packing section of the adjacent packing unit.

[0007] Furthermore, one end of the air guide tube is a conical connector, and the other end of the air guide tube is a conical insertion interface. The conical connector on the corrugated packing sheet is inserted into the corresponding conical insertion interface on the adjacent corrugated packing sheet.

[0008] Furthermore, a packed air-guided cooling tower further includes a square tower body, a left baffle plate, a right baffle plate, an exhaust fan, and a water collection tank. The packed module is located inside the square tower body, the exhaust fan is located at the top of the square tower body and directly above the packed module, and the water collection tank is located at the bottom of the square tower body and directly below the packed module. The left and right sides of the square tower body are respectively provided with a left air inlet and a right air inlet. The left and right baffle plates are respectively located at the left and right air inlets. The conical joint on the rightmost corrugated packing plate of the packed module passes through the right baffle plate and communicates with the outside atmosphere. The conical insertion interface on the leftmost corrugated packing plate of the packed module is connected to one end of the left air distribution pipe, and the other end of the left air distribution pipe passes through the left baffle plate and communicates with the outside atmosphere.

[0009] Furthermore, an auxiliary left blower is provided at the left air inlet, and a left dust filter is provided around the auxiliary left blower; an auxiliary right blower is provided at the right air inlet, and a right dust filter is provided around the auxiliary right blower.

[0010] Furthermore, the left air baffle plate has a left ventilation opening on its surface, and a left airflow size adjustment mechanism is provided at the left ventilation opening to adjust the size of the left ventilation opening; the right air baffle plate has a right ventilation opening on its surface, and a right airflow size adjustment mechanism is provided at the right ventilation opening to adjust the size of the right ventilation opening.

[0011] Furthermore, the left airflow magnitude adjustment mechanism has the same structure as the right airflow magnitude adjustment mechanism.

[0012] Furthermore, the right airflow size adjustment mechanism includes a servo motor, an adjustment disk, and an adjustment plate. The adjustment plate is mounted on the adjustment disk and is in close contact with the right ventilation opening on the surface of the right air baffle. The adjustment disk is mounted on the output shaft of the servo motor.

[0013] Furthermore, the adjustment plate is fan-shaped.

[0014] Furthermore, a spray assembly is provided inside the square tower body and above the packing module.

[0015] The beneficial effects of this invention are as follows: This invention designs the corrugated packing sheet into multiple packing sheet units. Each packing sheet unit has an airflow channel in the packing sheet and multiple air jet holes are added to the lower surface of the packing sheet. This design can remove the heat accumulated in the packing sheet itself to reduce the temperature of the corrugated packing sheet itself, thereby greatly improving the heat exchange efficiency.

[0016] The left and right baffle plates of this invention are provided with ventilation openings. A portion of the airflow enters the square tower body through the ventilation openings and directly exchanges heat with the cooling water. At the same time, another portion of the airflow from the outside enters the corrugated packing sheet and indirectly exchanges heat with the water outside the corrugated packing sheet, realizing simultaneous dry and wet heat exchange. In particular, when a portion of the airflow is ejected from the corrugated packing sheet, it mixes with the airflow of the wet heat exchange to form a swirling flow, which increases the contact time between the airflow and the water, resulting in a longer and more thorough heat exchange.

[0017] The invention also includes two auxiliary fans to improve the kinetic energy of the airflow.

[0018] The present invention also adds a left airflow size adjustment mechanism and a right airflow size adjustment mechanism to adjust the size of the left and right vents, thereby adjusting the ratio of dry heat exchange airflow to wet heat exchange airflow, so as to adjust the cooling tower to the optimal working state and maximize the heat exchange efficiency.

[0028] like Figure 4 , 5As shown, the packing module 2 includes multiple corrugated packing sheets 20 stacked together.

[0030] In this application, a portion of the external airflow enters the square tower body 1 through the left vent 13 on the left baffle plate 3 and the right vent 15 on the right baffle plate 4, and then passes upward through the packing module 2. During the process of passing through the gaps of the corrugated packing sheets 20 in the packing module 2, it directly exchanges heat with the water sprayed by the spray assembly 31. At the same time, another portion of the external airflow enters the corrugated packing sheets 20 through the conical joint 2 on the right side of the packing module 2 and the left air distribution pipe 32 on the left side of the packing module 2, and indirectly exchanges heat with the water outside the corrugated packing sheets 20. This also removes the heat accumulated in the corrugated packing sheets 20 themselves, thereby reducing the temperature of the corrugated packing sheets 20. This solves the problem in the prior art where the temperature of the corrugated packing sheets 20 increases due to long-term operation, thus reducing the heat exchange efficiency.
