technical field

Background technique

The working principle of micro-mist humidification is to use a high-pressure plunger pump to increase the water pressure to 4-7Mpa, and then atomize the pressurized water through a high-pressure resistant delivery pipeline through a professional nozzle to produce micron-sized micro-mist particles. It can quickly absorb heat from the air to complete vaporization and diffusion, thereby accomplishing the purpose of air humidification and cooling. This technology is often used in cigarette factory buildings. There are multiple installation slots evenly distributed on the machine board. A deflector hood is arranged in the installation groove. A nozzle connection seat is arranged on the machine board behind the deflector hood.
