Embodiment 1

[0025] Such as figure 1 As shown, a water-saving and white-smoke-proof composite closed-type cooling tower includes a tower body 1, and the tower body 1 is sequentially provided with a water collection tank 2, a heat exchange filler 3, a spray device 4, and a water eliminator 5 from bottom to top. , the heat exchange filler 3 is arranged on the filler frame, the side wall of the filler frame is a mesh structure, which is convenient for the discharge of water vapor, the top of the tower body 1 is provided with an air outlet, the air outlet is provided with an exhaust impeller 6, and the exhaust impeller 6 is arranged on the rotating shaft 7, the rotating shaft 7 is connected to the motor reducer 8 through transmission, and one end of the rotating shaft 7 passes through the spray device 4 and the water receiver 5 and is connected to the packing frame, so that the packing can be driven to rotate with the rotating shaft 7, and the heat exchange packing 3 can be put on the The mois...

Embodiment 2

[0031] A control method for a water-saving and white-smoke-proof composite closed cooling tower, comprising the following steps:

[0032] Step S1, obtaining the humidity value collected by the humidity sensor; the controller is used to obtain the humidity value collected by the humidity sensor installed in the tower body 1. In this example, the controller can use a single-chip microcomputer.

[0033] Step S2, judging whether the humidity value matches the preset humidity threshold; after the controller acquires the humidity value, compares the humidity value with the preset humidity threshold stored inside.

[0034] Step S3, if yes, generate a control signal; the controller outputs a corresponding control signal according to the comparison result.

[0035] Step S4. Control the speed of the motor reducer according to the control signal; and the controller adjusts the speed of the motor reducer according to the corresponding control signal, so as to achieve the purpose of intell...

Abstract

The invention discloses a water-saving and white smoke-resisting composite closed cooling tower and a control method thereof. The cooling tower comprises a tower body. The tower body is internally provided with a water collecting tank, heat exchanging filing materials, a spraying device and a water collecting machine from bottom to top. The heat exchanging filling materials are arranged on a filling material bracket. An air outlet is formed in the top of the tower body. An exhausting impeller is arranged at the air outlet. The exhausting impeller is arranged at a rotating shaft. The rotating shaft is in transmission connection with a motor decelerator. One end of the rotating shaft penetrates through the spraying device and the water collecting machine and is connected with the filling material bracket. According to the control method, the rotating speed of the motor decelerator can be adjusted based on the real-time humidity in the tower body, intelligent smoke exhausting is achieved,and resources are not wasted. The water-saving and white smoke-resisting composite closed cooling tower has the advantages of saving water and an excellent white smoke resisting effect.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a water-saving and white smoke-proof composite closed cooling tower and a control method thereof. Background technique [0002] The function of the cooling tower is to exchange heat between the circulating water carrying waste heat and the air in the tower, transfer the heat of the water to the air and disperse it into the atmosphere, and cool down the circulating water. The Chinese utility model patent titled "Low Feather Fog Water-Saving Cooling Tower" with the application number "201720588601.8" discloses a low-feather fog water-saving cooling tower, which includes a tower body and an air duct arranged on the tower body. The body is provided with water eliminators, water distributors, fillers and water collection tanks in sequence from top to bottom. An air inlet is provided below the side wall of the tower body, and a fan is provided in the air duct; an atomization dev...
