Description

Technical Field

[0001] The utility model relates to an air purification device in the field of environmental protection, in particular to a plant liquid air purification device. Background Art

[0002] Plant liquid deodorization (air purification) is a commonly used process in the field of environmental protection. It is generally used in areas such as leachate pools and sewage ditches in garbage transfer stations. These areas have the highest and most concentrated odor concentrations and gather on the ground or lower, making them difficult to collect. Diffuse unorganized odors are usually atomized by plant liquid. A high-pressure pump is used to transport a plant liquid solution diluted to a certain concentration to an infusion pipe, where it is sprayed out in a fine mist through a high-pressure nozzle. The odor is captured through the adsorption and sedimentation of fine droplets and reacts with molecules in the plant liquid solution to achieve the effect of eliminating odor (air purification). However, this process has the following problems: 1. The aperture of the high-pressure nozzle is very small, and the nozzle is prone to clogging in the operating environment; 2. The operation process uses a diluted plant liquid solution, and the atomization effect increases the humidity of the air, which may make the equipment surface and the ground below the atomization area moist, accelerate equipment aging, and reduce the service life of the equipment. At the same time, operators will also feel uncomfortable when passing through the water mist when the equipment is running; 3. The consumption of plant liquid is large; 4. The placement, arrangement and pipeline laying of multiple high-pressure nozzles, infusion tubes, drug delivery equipment and other devices are very complicated, and the space required is large.
