Noise reduction spraying device

The utility model discloses a noise reduction spraying device. Comprising a tubular shell, an air supply device, a sprayer, a rectification structure and a counter weight. The tubular shell is provided with an air inlet and an air outlet; the air supply device is connected with the air inlet of the tubular shell and used for outputting airflow into the tubular shell. The sprayer is connected with the air outlet of the tubular shell, and the sprayer is used for spraying atomized liquid to airflow output from the air outlet of the tubular shell; the rectifying structure is arranged in the tubular shell and used for adjusting turbulent flow in the tubular shell to convert the turbulent flow into steady flow; and the counterweight is rigidly connected with the tubular shell and is used for increasing the weight of the tubular shell, so that the tubular shell is difficult to resonate under the action of aerodynamic force. According to the utility model, the airflow in the tubular shell is adjusted through the rect
