Problems solved by technology

The principle of this method is generally to charge the particles through a high-voltage ionization device, so that the charged particles enter the electrostatic field, such as a parallel plate electric field, because the opposite charges attract each other, so the charged particles are adsorbed on the electrode opposite to its polarity on the board, so as to achieve the filtration of particles, but this method will have a serious problem of secondary pollution. After the charged particles are captured by the electrostatic field, the charged particles are neutralized, and with the flow of air, they are released again air out

Embodiment 1

[0029] figure 1 It is a schematic structural diagram of a particulate matter trapping device provided in Embodiment 1 of the present invention, which can be used to trap particulate matter in gas, and the device specifically includes: a filter brush ( figure 1 not shown), housing 10 and gas ionization device 20, wherein,

[0030] The air inlet surface of the casing 10 runs through several through holes to the air outlet surface of the casing 10, and filter brushes are inserted one by one in the through holes, and the filter brushes are in contact with the side walls of the corresponding through holes. The casing 10 is made of conductive metal, and the filter brushes Including piezoelectric materials, the gas ionization device 20 is installed on the air intake surface of the housing 10, and the air flows through the gas ionization device 20 to charge the particles in the air flow and then pass through the through hole. When the air flows through the through hole, the air will ...

Embodiment 2

[0047] This embodiment is further optimized on the basis of the foregoing embodiments. In this embodiment, the filter brush includes a brush rod and brush filaments, and the brush filaments are fixed around the brush rod, so that after the charged particles enter the corresponding through holes, there are brush filaments in all directions to block and enhance the collection. Particle effect.

[0048] In the above solution, optionally, the brush rod is made of conductive metal, and the brush wire is made of piezoelectric material.

[0049] In the above solution, optionally, one end of the brush filament is fixed on the outer wall of the brush rod, and the other end of the brush filament is in contact with the side wall of the corresponding through hole.

[0050] When the brush rod is made of conductive metal, after the air enters the corresponding through hole, the pressure of the air on the brush wire makes the brush wire deform, and then the end of the brush wire fixed on th...

Description

technical field [0001] The invention relates to the technical field of purification and filtration, in particular to a particle trapping device. Background technique [0002] Since the air is accompanied by particulate matter, it is often necessary to filter the particulate matter in the air when a clean space is required. For example, for industries such as PCB (Printed Circuit Board, printed circuit board), LCD (Liquid Crystal Display, liquid crystal display) or precision instruments, it is necessary to filter particulate matter at the air outlet of the air conditioner in the dust-free purification workshop to send clean air into the in the workshop. [0003] At present, there are two most common particulate filter methods, one of which is a filter method, such as HEPA (Highefficiency particulate air Filter, high-efficiency air filter). However, this kind of equipment has a large wind resistance, and high-power equipment is required to provide power for the air, so it wi...
