Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, in particular to a high-position water collecting machine power ventilation cooling tower with one well and multiple towers for water distribution in the tower. 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. The cooling process uses water and air flow to exchange heat to produce 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. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through an evaporative heat dissipation device to ensure the normal operation of the system. The device is generally tower-shaped, hence the name cooling tower.

[0003] The water supply pipe of the existing cooling tower is exposed outside the tower body, which occupies a large area, is not aesthetically pleasing, and is difficult to meet the current needs of industrialization, and the water distribution is not uniform. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a water distribution scheme in which a vertical shaft or a pipeline vertical shaft is arranged in a high-level water collecting machine force ventilation cooling tower or a multi-tower water distribution scheme.

[0005] The technical solution for achieving the purpose of the present invention is: a one-well, multi-tower, water-distributing, high-position water-collecting mechanical ventilation cooling tower, the cooling tower comprising a tower body, an air inlet, a top air outlet, a top exhaust device, a water distribution system, and a high-position water collection device; the lower section of the tower body side wall is provided with an air inlet, the top is provided with a top air outlet, the top is provided with a top exhaust device, the top air outlet is provided with a top exhaust device, the tower body below the top air outlet is provided with a water distribution system and a high-position water collection device in sequence from top to bottom; an upper tower shaft or pipeline is also vertically provided in the tower body, and the upper tower shaft or pipeline is connected to the water distribution system.

[0006] Furthermore, the water distribution system includes a water distribution main pipe and a water distribution branch pipe; the water distribution main pipe is arranged in the upper tower shaft or the upper part of the pipeline and is connected to the upper tower shaft or the pipeline, and the water distribution main pipe is connected to a plurality of water distribution branch pipes.

[0007] Furthermore, a horizontally arranged water distribution trough is provided on each side of the tower wall of the tower body of two adjacent cooling towers, and the two water distribution troughs are connected to the upper tower shaft or pipeline vertically arranged on the tower wall, and the water distribution trough is connected to the water distribution system.

[0008] Furthermore, an intermediate high-position water collecting trough is horizontally arranged between two adjacent tower bodies, the intermediate high-position water collecting trough is connected to the high-position water collecting device, and the water distribution trough is a closed structure as a whole.

[0009] Furthermore, there are a plurality of cooling towers, which are installed on the ground back to back. The middle high-position water collecting tank is arranged in the tower wall opposite to the air inlet, and the water distribution tank is arranged on both sides of the middle high-position water collecting tank. The upper tower shaft or pipeline is set between every two cooling towers and fixed on the outside of the tower wall opposite to the air inlet. The upper tower shaft or pipeline is fixed at the central position of the tower wall where it is installed, and the water distribution tank is directly connected to the upper tower shaft or pipeline.

[0010] Furthermore, there are a plurality of cooling towers, which are installed back to back on the ground, the middle high-level water collecting trough is arranged in the tower wall opposite to the air inlet, the upper tower shaft or pipeline is arranged between every two cooling towers, the water distribution trough and the middle high-level water collecting trough are arranged to intersect, and the upper tower shaft or pipeline is arranged below the water distribution trough and is connected to the central position of the water distribution trough.

[0011] After adopting the above technical solution, the present invention has the following positive effects:

[0012] (1) The present invention sets a water distribution shaft and a main water distribution tank in the weak wind zone at the far end of the single-sided wind inlet tower, and adopts a shaft-water tank type water distribution with more uniform water distribution, which better ensures uniform water distribution and minimizes the impact on the flow field in the tower, while improving the space utilization rate of the weak wind zone; the water distribution shaft also plays the role of a pressure regulating well, ensuring the uniformity of water distribution.

[0013] (2) The water distribution shaft of the present invention is placed inside the tower, eliminating the water distribution riser outside the tower, which can ensure that the entire tower has a neat appearance and beautiful structure. Especially when there is a need for deindustrialization of urban power plants, the cost of deindustrialization can be greatly saved.
