Problems solved by technology

[0002] The indoor fresh air system is mainly to remove the particulate matter in the gas by drawing the outdoor air into the room by passing the gas through the filter plate. With high wind pressure, the airflow will generate noise, and the fan will also generate noise, so that when the indoor fresh air system is running, there will be sharp noise and fan noise, causing discomfort to indoor users
At present, there are some fresh air systems that use electrostatic dust removal and spray dust removal. This type of fresh air system will perform a certain degree of humidification effect on the gas entering the room, which will greatly improve the comfort of users. At the same time, there are also some noise-reducing fresh air systems. The system can reduce the noise of the airflow by adding curves or noise reduction strips, but this type of fresh air system requires a relatively high wind pressure due to the fan, so the flow rate of the airflow is relatively high, so the density of the noise reduction strips and the noise reduction strips The cooperation between needs higher requirements
At present, there are also some gas scrubbers that pass gas through the water body for gas purification, but this type of device needs to pass the gas from the bottom of the water body to form bubbles, but if it is passed from the bottom, the gas that needs to be input has a relatively large Air pressure (otherwise the water will flow back into the gas pipeline), so this type of gas treatment device also requires a large fan power to provide a relatively large air pressure, and it is difficult to reduce the fan noise

Abstract

The invention relates to a high-efficiency and low-noise fresh air device, comprising an air inlet pipe part, a washing chamber part, a first water treatment chamber part, a second water treatment chamber part, an exhaust pipe part and a bubble-breaking water treatment chamber part. Through specific settings of each component, relatively low fan power and relatively low airflow speed are achieved, so that the noise reduction effect of the fresh air system is improved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a high-efficiency and low-noise fresh air device. Background technique [0002] The indoor fresh air system mainly removes the particulate matter in the gas by drawing the outdoor air into the room and passing the gas through the filter element plate. Large wind pressure, the airflow will generate noise, and the fan will also generate noise, so that the sharp noise and fan noise will exist when the indoor fresh air system is running, causing discomfort to indoor users. At present, there are some fresh air systems that use electrostatic dust removal and spray dust removal. Such fresh air systems will humidify the air entering the room to a certain extent, which will greatly improve the comfort of users. At the same time, there are also some noise reduction fresh air systems. System, the noise reduction of the airflow is achieved by adding curves or noise reduction strips, but this...
