Description

Technical Field

[0001] The invention relates to the field of cooling technology, and in particular to an energy-saving flow-guiding device for a cooling tower duct and a method thereof. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. The device is generally barrel-shaped, hence the name cooling tower.

[0003] As the cooling water in the cooling tower will evaporate, part of the evaporated water will not condense and will enter the wind duct along with the air in the tower, and then be discharged directly into the atmosphere from the wind duct.

[0004] Therefore, on the one hand, it will cause the loss of cooling water. On the other hand, when the evaporated water vapor is discharged, it will adhere to the gas shell in the tower and will be discharged in the form of "mist", polluting the working environment. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an energy-saving flow-guiding device for a cooling tower duct and a method thereof.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A cooling tower air duct energy-saving flow guide device includes multiple groups of condensation nodes connected by flanges, wherein the condensation node at one of the two ends is fixed to the air outlet of the air duct, and the condensation node at the other end is placed in the atmosphere, the condensation node includes a shell, a baffle arranged inside the shell, and a liquid collecting barrel is fixedly installed on the bottom outer wall of the shell.

[0008] Preferably, the baffles are arranged in an up-and-down staggered manner.

[0009] Furthermore: the baffle is a hollow structure.

[0010] On the basis of the above scheme: the two ends of the baffle are rotatably connected to the inner side of the shell through hollow shaft 1 and hollow shaft 2, and hollow shaft 1 and hollow shaft 2 are both connected to the inner cavity of the baffle, and hollow shaft 1 and hollow shaft 2 are connected to the same set of auxiliary cooling circulation components.

[0011] A better solution in the above solution is: the auxiliary cooling circulation component includes a coolant tank and a pump, the hollow shaft one is connected to the water outlet of the pump through a hose one, and the hollow shaft two is connected to the coolant tank through a hose two.

[0012] As a further solution of the present invention: a liquid level sensor is arranged inside the coolant tank.

[0013] At the same time, a group of partitions is fixedly installed on the inner wall of the baffle, and the group of partitions is arranged in an up-and-down staggered manner.

[0014] As a preferred embodiment of the present invention: an outer wall of one side of the shell is provided with an adjustment component, the adjustment component includes a pulley fixedly mounted on an outer wall of a hollow shaft and a clamping wheel rotatably connected to the outer wall of the shell through a wheel axle, and the outer wall transmission of the pulley and the clamping wheel is cooperated with the same synchronous belt.

[0015] At the same time, a connecting shaft is fixedly installed on the outer wall of the wheel axle, a worm wheel is fixedly installed on the outer wall of the connecting shaft, a worm is meshed on the top of the worm wheel, and the worm is rotatably connected to the side wall of the shell through a support plate; when the worm rotates, it can drive the worm wheel to rotate, thereby driving the clamping wheel to rotate through the connecting shaft and the wheel axle.

[0016] As a more optimal solution of the present invention: the air outlet of the condensation node located in the air is provided with a filter element, the filter element is formed by a plurality of sponges bonded to each other, and the inside of the sponge is wrapped with a retaining frame, and activated carbon particles are placed on the inner wall of the retaining frame.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention provides a condensation node with a baffle inside. When the gas passes through the shell, it will exchange heat with the inner wall of the shell and the baffle, so that the water vapor can be condensed. The condensed water enters the liquid collection barrel, preventing water loss and environmental pollution caused by direct discharge into the atmosphere.

[0019] 2. The present invention, by arranging the baffles in an up-and-down staggered arrangement, can increase the path of the gas in the shell, thereby increasing its cooling time and improving the condensation effect of water vapor.

[0020] 3. The present invention, by setting the baffle as a cavity and cooperating with an auxiliary cooling circulation component, can cool the baffle after the temperature rises due to absorbing heat through the coolant, thereby reducing its surface temperature and improving its heat exchange efficiency with water vapor.

[0021] 4. The present invention, by setting an adjustment component, can change the overlapping area of ​​the baffle plate located on the horizontal plane projection, change the limiting and guiding function of the gas path, thereby realizing the change of the gas path, so that the gas path can be adjusted according to the specific water vapor content, thereby improving the flexibility of use.

[0022] 5. The present invention, by providing a sponge and activated carbon particles, can, on the one hand, adsorb the water vapor that has not yet condensed to improve the purification function, and on the other hand, the sponge can also play a filtering role to prevent the polluted particles in the gas from polluting the environment.

When the gas passes through the shell 3, it will exchange heat with the inner wall of the shell 3 and the baffle 4, so that the water vapor can be condensed, and the condensed water enters the liquid collecting barrel 6, preventing water loss and environmental pollution caused by direct discharge into the atmosphere.

[0036] In addition, the device can increase the path of the gas in the shell 3 by arranging the baffles 4 in an up-and-down staggered manner, thereby increasing its cooling time and improving the condensation effect of water vapor.

[0037] In order to solve the condensation rate problem; Figure 4 As shown, the baffle 4 is a hollow structure, and its two ends are rotatably connected to the inner side of the shell 3 through a hollow shaft 1 7 and a hollow shaft 2 9, and the hollow shaft 1 7 and the hollow shaft 2 9 are both connected to the inner cavity of the baffle 4, and the hollow shaft 1 7 and the hollow shaft 2 9 are connected to the same set of auxiliary cooling circulation components.

[0039] A liquid level sensor 22 is disposed inside the coolant tank 20 , and the liquid level sensor 22 can monitor the coolant in the coolant tank 20 .

[0040] A group of partition plates 8 is welded to the inner wall of the baffle plate 4, and the group of partition plates 8 is arranged in an up-and-down staggered manner.

[0041] By setting the baffle 4 as a cavity and cooperating with an auxiliary cooling circulation component, the baffle 4 whose temperature rises due to absorbing heat can be cooled by the coolant, thereby reducing its surface temperature and improving its heat exchange efficiency with water vapor.

[0042] In addition, by providing the partition plate 8 , the flow path of the coolant in the baffle plate 4 can be increased, thereby ensuring the cooling effect of the baffle plate 4 .
