Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention is described in detail below with reference to the accompanying drawings, and the description in this section is only exemplary and explanatory, and should not have any limiting effect on the scope of the present invention.

Referring to fig. 1 to 4, in a specific embodiment, a low noise open type cross flow cooling tower includes a filler 1 disposed at both sides of a tower body and a fan system 2 disposed at an upper end of the tower body; the fan driving mechanism 6 of the fan system 2 is arranged in the tower body; an air outlet at the upper end of the tower body is provided with a silencing barrel 4; the inner wall of the silencing barrel 4 is provided with silencing cotton 42; the fan system 2 adopts a wide-blade fan 3.

Under the condition of a certain load, the rated air quantity of the fan is constant. The rotating speed of the fan is lower due to the wide blades, the rotating speed of the wide blades is low, and the noise is lower. The wide-blade fan can adopt a four-blade fan with the diameter of 215cm and the aperture of 50mm and the large wide-blade aperture depth of 110 m. The leaf width is generally 530 or 660; whereas a conventional fan blade has a width of only 300 a.

As shown in fig. 3, the fan driving mechanism 6 generally includes a driving motor portion, a belt transmission mechanism portion; the fan driving mechanism 6 is arranged on the support of the tower body and is positioned at the top end inside the tower body.

As shown in fig. 2, further optimization is performed on the basis of the above embodiment: and air inlet shutters 5 are arranged on the outer side of the filler 1. The air inlet shutter 5 can be made of PVC material; the air inlet shutter 5 can prevent external impurities from entering the tower to block the filler, prevent sunlight from directly irradiating the water collecting basin to influence water quality, and further reduce noise transmitted from the air inlet.

Further optimization is carried out on the basis of the embodiment: the upper port of the silencing barrel 4 is provided with a protective net 41. The protection net 41 can prevent foreign objects from falling into the blower.
