A ventilation pipeline device for humidification and noise reduction

Abstract

The invention provides a humidifying and silencing ventilation pipeline device. A plurality of supporting racks are included and arranged in a ventilation pipeline. The section of each supporting rackis in a symmetric streamline shape, the head-tail direction of each supporting rack is kept to be consistent with the gas flowing direction, and gas jet flow flows towards the tails of the supportingracks from the heads of the supporting racks. An inner pipeline is arranged on the inner side of the front portion of each supporting rack, and a plurality of water spraying holes are formed in the wall faces of the two sides of the front portion of each supporting rack, wherein the inner pipeline comprises a driver, a transmission rod, a supporting pipe, an inner water conveying pipe and a rotary water spraying pipe, water can be sprayed from the positions of the water spraying holes, and the water spraying direction can be adjusted. Drying layers are arranged on the two sides of the rear portion of each supporting rack, water discharging grooves are formed in the lower positions of the drying layers, and the drying layers can absorb water of the surrounding environment and discharge water into the water discharging grooves. The water discharging grooves communicate with a water discharging pipe outside the ventilation pipeline. According to the humidifying and silencing ventilationpipeline device, on the basis of optimizing of the pipeline inner gas flow field, the humidifying noise lowering technology is utilized, spreading of noise in the ventilation pipeline is restrained, and background noise is lowered.

Description

technical field [0001] The invention relates to the technical field of system noise reduction for ventilation pipelines, in particular to a ventilation pipeline device for humidification and noise reduction. Background technique [0002] The gas in the ventilation pipeline flows unsteadily, and the interaction between the gas and the objects in the pipeline will generate aerodynamic noise; during the manufacturing or installation of mechanical equipment, mechanical noise will be caused due to process defects, such as fan bearing noise, noise caused by belt and transmission , the noise caused by the unbalanced rotor, the vibration noise of the casing and the pipeline, etc.; these noises are collectively referred to as the background noise of the ventilation pipeline. Excessive background noise will radiate a large amount of noise to the environment, affect the working status of related equipment, arouse the chattering response of ventilation pipeline components, cause structu...
