Evaporation and heat-exchange periodic water replenishment device

Abstract

The invention discloses an evaporation and heat-exchange periodic water replenishment device which can obtain higher evaporation and heat-exchange efficiency compared with the current continuous water replenishment manner used for periodic water replenishing for evaporation and heat-exchange device. The water replenishment device comprises a shunting main body and a rotary water replenishment pipe arranged in the shunting main body, wherein a plurality of shunting ports are arranged on the shunting main body at intervals, and a nozzle is arranged on each shunting port; a plurality of water replenishment ports are arranged on the pipe wall of the rotating water replenishment pipe; and when the rotary replenishment pipe rotates opposite to the shunting main body, each water replenishment port is respectively and periodically communicated with the shunting port correspondingly arranged on the shunting main body. The invention designs the evaporation and heat-exchange periodic water replenishment device which realizes periodic water replenishment according to necessary process time and necessary space-time concept of low humidity space acquired by metal surface water evaporation and gains the process time and the low-humidity space acquired by surface water evaporation, thereby obtaining higher evaporation and heat-exchange efficiency. The water replenishment device is especially suitable for an evaporation heat exchanger of metal surface evaporation and heat-exchange facilities with rectangular platy external characteristics.

Description

technical field [0001] The invention relates to a device for periodically replenishing water to an evaporation heat exchanger. Background technique [0002] In the technology of heat transfer by evaporation of water on the metal surface, since evaporation is mainly through the "mass exchange" process of "water-water vapor", the purpose of heat transfer to the ambient air is realized, and water consumption will inevitably occur in the process. For this process to continue, it is necessary to provide supplementary water sources. Although the manifestations of water evaporation on the metal surface are diverse, the replenishment of evaporated water sources has always been continuous. In fact, continuous water replenishment is not conducive to the evaporation of surface water. The evaporation process itself relies on the diffusion of water vapor molecules. In an environment with high humidity, its efficiency will decrease. At the same time, the thickness of the water film on ...

In fact, continuous water replenishment is not conducive to the evaporation of surface water. The evaporation process itself relies on the diffusion of water vapor molecules. In an environment with high humidity, its efficiency will decrease

At the same time, the thickness of the water film on the metal surface objectively has an optimal thickness with the highest heat transfer efficiency, and continuous water replenishment is difficult to ensure that the thickness of the water film is controlled at the optimal state
