Description

Technical Field

[0001] The present application belongs to the technical field of air purifiers, and in particular to a high-pressure spray absorption device. Background Art

[0002] Formaldehyde is the most common toxic and harmful gas. As the most common pollutant in daily life, formaldehyde lasts for a long time. The indoor heating season in winter in the north has become a high volatility period of formaldehyde, benzene and other decoration pollutants in a year; PM2.5 has a small particle size, a large area, and strong activity. It is easy to carry toxic and harmful substances (for example, heavy metals, microorganisms, etc.), and it stays in the atmosphere for a long time and is transported over a long distance, so it has a greater impact on human health and the quality of the atmospheric environment. As the above-mentioned harmful gases are becoming more and more common in life, air purifiers are receiving more and more attention. Air purifiers for home use are already relatively common, and large commercial air purifiers are needed in public places and some large conference rooms and other confined spaces.

[0003] Most of the current large-scale commercial air purifiers use passive air purifiers. The working principle is to use a fan to draw indoor air into the machine, filter it through a built-in filter or other filter element, and then discharge it. This filtering method has low purification efficiency and requires frequent replacement of filters or filter elements, which has high maintenance costs. Utility Model Content

[0014] Ambient air enters from the air inlet and forms water mist after being sprayed by the spray chamber. The multi-faceted hollow ball has a large contact area and will intercept part of the water mist. The water mist in contact with the multi-faceted hollow ball will turn back into liquid to prevent the water mist from moving upward with the air flow. Then the rattan cotton layer will filter the remaining water mist to ensure that the air going out from the air outlet is dry.

The water pressure sensor can detect the pressure of the water line to prevent pipe blockage and work with the controller to protect the operation of the system. When the temperature and water pressure are abnormal, a reminder will be given through the alarm device set on the device. If there is human intervention, the reminder can be stopped. If the temperature and water pressure continue to be abnormal for more than 5 minutes, the controller controls to stop the spray washing to avoid water pipe rupture. For more than 15 minutes, the controller controls to automatically stop the entire purifier to avoid other effects caused by excessive temperature. In addition to being able to be connected to the water replenishment pump, the water adding pipe can also be manually replenished. The water pump and the drain pipe can cooperate to have the internal drainage function of the water storage tank.
