Description

Novel countercurrent open cooling tower Technical Field The utility model relates to the technical field of cooling towers, in particular to a novel countercurrent open cooling tower. Background The countercurrent open cooling tower is cooling equipment, is mainly used for cooling hot water, can be recycled, and is widely applied to the fields of industrial production, central air conditioning systems and the like. The working process of the cooling tower in the prior art is that outside air enters the cooling tower from the air inlet under the action of the fan, hot and humid water is sprayed into the cooling tower from the spray header, the water is in direct contact with the air, and the heat of the water is evaporated, so that cooling water is cooled, but the water and the air are in direct contact for heat exchange, water loss is increased, and the cooling tower cannot be adjusted according to different outside temperatures, so that water resources are not saved. Disclosure of utility model The utility model aims to solve the problems in the related art, and provides a novel countercurrent open cooling tower, which solves the problems that water and air are in direct contact, white fog is generated and water loss is increased, and also solves the problem that the operation process of the cooling tower cannot be adjusted according to the change of the external temperature. In order to solve the problems, the following technical scheme is provided: The novel countercurrent open cooling tower comprises a tower body, wherein a first air inlet is formed in the lower portion of the outer wall surface of one side of the tower body, a heat exchange structure is arranged in the middle of the tower body, the heat exchange structure is obliquely arranged, a gas passage and a water passage are arranged in the heat exchange structure and are not communicated with each other, a first spraying mechanism is arranged in the tower body above the heat exchange structure, an air outlet is formed in the top of the tower body, a fan is arranged in the air outlet, and a water collecting tank is arranged at the bottom of the tower body. According to the scheme, through the arrangement of the heat exchange structure, when the ambient temperature is proper in spring and autumn, the first spraying mechanism is only required to be started, hot water flows into the water channel of the heat exchange structure downwards after being uniformly sprayed from the first spraying mechanism, meanwhile, external cold air flows into the tower body from the first air inlet under the drive of the fan, flows upwards along the air channel of the heat exchange structure and is fully contacted with hot water in the water channel, effective cooling of the hot water is realized through efficient heat exchange, when the ambient temperature is obviously increased, for example in summer, the first spraying mechanism and the second spraying mechanism are synchronously started, at the moment, under the suction effect of the fan, the first air inlet and the second air inlet are cooperatively operated, a large amount of cold air flows into the tower rapidly, and the hot water sprayed by the first spraying mechanism and the second spraying mechanism is cooled respectively, so that the problem of large amount of water loss caused by direct contact of the water and the air in the traditional cooling tower is solved, when the water and the air are not in direct contact, the white fog is effectively eliminated, and the cooling tower can adjust the internal operation lifting capacity according to the change of the external temperature, so that the cooling efficiency and the energy-saving effect are greatly improved.
