Adjustable, optimized and energy-saving ventilation and noise reduction device of cooling tower

Abstract

The invention discloses an adjustable, optimized and energy-saving ventilation and noise reduction device of a cooling tower. A tower body is of a hollow cuboid frame structure; partition walls are arranged on the two sides of the tower body respectively; an air inlet silencer is arranged in the partition walls; a treatment bin is arranged at the bottom in the tower body; air ducts are arranged atthe top of the treatment bin; the air ducts are each of an inverted-cone-shaped structure; an arc-shaped cover is arranged at the bottom of the corresponding air duct; an exhaust port is formed in the top of the corresponding air duct; an exhaust fan is arranged in the corresponding exhaust port; exhaust cylinders are arranged at the top of the tower body; the air inlet silencer is composed of aplurality of oval wing blades which are sequentially arranged at intervals from top to bottom; and the wing blades are filled with sound absorption cotton layers. According to the adjustable, optimized and energy-saving ventilation and noise reduction device, the wing blades are designed to be oval, the air ducts are designed to be of an inverted-cone-shaped structure, and the fans are arranged atthe exhaust ports, such that the air inlet efficiency and the air outlet efficiency are improved, and the aerodynamic performance is excellent; and meanwhile, sound absorption materials are arrangedin the partition walls and the wing blades, and the air inlet efficiency is controlled by adjusting opening and closing of the wing blades.

Description

technical field [0001] The invention relates to the technical field of cooling tower noise reduction, in particular to a ventilation noise reduction standard device for cooling towers that can be adjusted for energy saving. Background technique [0002] With the improvement of environmental protection requirements in our country, the overall noise requirements near hotels and commercial residential areas or industrial areas are gradually strict, and then extended to the noise standards of individual structures in industrial areas. The host cooling system or auxiliary cooling system of hotels and commercial buildings usually adopts mechanical ventilation cooling towers. The noise of fan operation, motor operation noise, and water drop noise of cooling towers have become the problems that need to be solved for the overall noise reduction of cooling towers. [0003] In the prior art, the ventilation efficiency of the cooling tower is slow, and other ventilation equipment is oft...

Problems solved by technology

[0003] In the prior art, the ventilation efficiency of the cooling tower is slow, and often requires the assistance of other ventilation equipment, so as to speed up the ventilation efficiency. This method not only consumes a lot of energy, but also has poor effect
