Description

TECHNICAL FIELD

[0001] The utility model relates to a cooling tower, specifically to a partition type dry-wet combined cooling tower. BACKGROUND

[0002] The counterflow closed cooling tower is a kind of high-efficiency cooling equipment, and is widely used in industrial and commercial fields to reduce the temperature of circulating water.It combines the characteristics of closed cooling tower and counterflow cooling tower, which not only ensures the cleanliness and recycling of cooling water, but also improves the cooling efficiency.

[0003] In the existing cooling tower, the medium to be cooled is usually sent into the medium cooling mechanism, and the cooling action on the medium to be cooled is realized by spraying cooling water with lower temperature on the medium cooling mechanism.The process of obtaining cooling water for spraying on the medium cooling mechanism is that the spraying mechanism pumps away hot water at the bottom of the cooling tower and sprays it on the partition type cooling mechanism.At the same time, air with lower temperature than the hot water at the bottom of the cooling tower is sent into the cooling tower.The air with lower temperature and the hot water with higher temperature exchange heat in the partition type cooling mechanism, and finally the air is heated and pumped out of the cooling tower by the fan, and the hot water at the bottom of the cooling tower is cooled and sprayed on the medium cooling mechanism.

[0004] In the existing cooling tower, when the same cooling tower is in winter, the cooling effect of the medium to be cooled in the medium cooling mechanism can be ensured by the hot air and the hot water at the bottom of the cooling tower after heat exchange, so as to ensure the cooling effect of the cooling tower.However, in summer, the cooling range of the hot water at the bottom of the cooling tower is small after heat exchange between the hot air and the hot water at the bottom of the cooling tower, which will affect the cooling range and cooling rate of the medium to be cooled, thereby affecting the cooling effect of the cooling tower. TECHNICAL CONTENT

[0006] To solve the above problems, the following technical solutions are provided:

[0007] The application relates to a dry-wet combined cooling tower with a partition wall, which comprises a tower body, a spraying water cooling mechanism in the tower body, a medium cooling mechanism below the spraying water cooling mechanism, and a medium cooling mechanism below the spraying water cooling mechanism, wherein spraying water falls into the medium cooling mechanism after being cooled by the spraying water cooling mechanism to cool the medium in the medium cooling mechanism; the spraying water cooling mechanism comprises a partition wall cooling mechanism arranged obliquely in the tower body, which divides the inner cavity of the tower body into two staggered and non-communicating compartments; the tower body side walls of two air inlet ends of the partition wall cooling mechanism are provided with first air inlets which are in communication with the corresponding compartments and are provided with first louvers; and the medium cooling mechanism comprises two medium cooling mechanisms which are arranged in the compartments below the partition wall cooling mechanism in a one-to-one correspondence, the tower body side walls below the medium cooling mechanisms are provided with second air inlets which are in communication with the corresponding compartments and are provided with second louvers.

[0013] The partition wall cooling mechanism comprises a plurality of fillers arranged in a stacked manner, and the adjacent fillers are connected to each other through water inlet channels for spraying water, and the water inlet channels are connected to two compartments above the partition wall cooling mechanism.

[0014] Through the above technical scheme, the sprayed hot water and the incoming air outside move in different channels in the partition wall cooling mechanism, so that they do not directly contact each other, and the gas discharged from the tower body after heat exchange is hot dry air, which avoids taking away the water source in the cooling tower, thereby realizing no water loss in the cooling tower.
