Spraying device and evaporative cooling system

Abstract

The embodiment of the invention provides a spraying device and an evaporative cooling system. The spraying device comprises a central pipe which is rotatably arranged by taking the axis of the central pipe as the center; the at least two spraying assemblies are distributed in a circumferential array around the axis of the central pipe; each spraying assembly comprises a spraying pipe and at least one first nozzle arranged on the spraying pipe; one end of the spraying pipe is connected with the water inlet end of the central pipe, and the other end extends away from the axis of the central pipe; the axis of the first nozzle and the axis of the central pipe are located in different planes. According to the structure, the mist sprayed by the first nozzle can generate counter-acting force which is not parallel to the axis of the central pipe, so that the spraying device can rotate under the counter-acting force of the mist. The spraying device can be applied to an evaporative cooling system, the spraying area can be increased on the premise that the number of the nozzles is reduced, spraying dead angles are reduced, mechanical driving structures such as a motor do not need to be used, reliability is high, and cost is low.

Description

Technical field [0001] The present application relates to the technical field of cooling equipment, in particular to a sprinkler device and an evaporative cooling system. Background [0002] In evaporative cooling systems, or industrial sprinklers, greenhouse sprinklers, forestry sprinklers, fire sprinklers, and other sprinkler systems or equipment, sprinklers are used to generate sprays for purposes such as lowering the target temperature of air or being cooled, irrigation, extinguishing fires, etc. [0003] The current spray device mainly includes a stationary spray device and a mobile spray device. Among them, the fixed spray device generally includes a number of spray rods juxtaposed at certain intervals and fixed settings, each spray rod is provided with multiple nozzles, and the water mist sprayed by each nozzle only covers the fixed area, so that when the spray area is large, the number of spray rods and nozzles required is too much, which will lead to a large flow of spr...

AI Technical Summary

Problems solved by technology

Among them, the fixed spray device generally includes a plurality of spray rods arranged side by side at certain intervals and fixedly arranged, and each spray rod is provided with a plurality of nozzles, and the water mist sprayed by each nozzle only covers a fixed area. In this way, when the spray area is large, too many spray rods and nozzles are required, which will lead to a large flow of water for spraying, and increase the complexity of the structure and the cost of spraying.

The mobile spray device includes a guide rod and a spray rod that can reciprocate on the guide rod driven by a motor. This type of spray device includes mechanical structures such as a guide rod and a motor, and is filled with water mist. It operates in a humid environment, so the reliability cannot be guaranteed. In addition, due to the influence of factors such as the guide rod stroke, this spray device may also have a spray dead angle.
