Abstract

The invention discloses a magnetically controlled porous medium dynamic air purification device and method in a fresh air system. A pulsed magnetic field is generated by a reversing magnetic field symmetrically arranged up and down, so that the metal porous medium in the device is rapidly reciprocated up and down by the magnetizing force to form a macro "Catching curtain" dynamically captures PM2.5-PM10. The magnetizing force in the device is much greater than the drag force of the air flow on the porous medium, which can keep the metal porous medium bound in the vertical space of the air purification device, and continuously capture without horizontal movement. The invention adopts a graded dust removal mechanism to remove dust specifically for particles of different sizes, reduce the dust removal pressure of a single-stage haze removal module, and remove haze efficiently. The invention can adjust the current change in the eddy current coil attached to the magnetic field device to form the eddy current thermal effect, heat the metal porous medium to preheat the fresh air; cooperate with the triangular fin channel and the honeycomb heat exchange core to form a multi-stage hierarchical heat exchange structure, and build a three-dimensional heat exchange system. Coupled with the fresh air system, it has dual functions of removing haze and preheating.

Description

technical field [0001] The invention relates to the technical field of environmental pollution prevention and control in the direction of fresh air, in particular, to a device and method for dynamic air purification of porous media driven by a reversing pulse magnetic field in a fresh air system. Background technique [0002] With the rapid development of the economy, the living environment of human beings is constantly changing, and the smog problem that follows is becoming more and more serious. Nowadays, when the problem of outdoor haze cannot be solved in a short time, the fresh air system that can form a "fresh air flow field" indoors and filter, disinfect, sterilize, increase oxygen and preheat the air entering the room has become a method to keep the indoor air fresh. , an effective way to isolate the impact of smog on people's living environment. [0003] Porous metal material is a new type of metal material containing a large number of connected or closed pores in ...
