Multi-stage ion air supply module

Abstract

The invention provides a multi-stage ion air supply module. The multi-level ion air supply module includes a multi-level discharge module, and the multi-level discharge modules are arranged in sequence, and the discharge module includes a plurality of discharge needles and a metal mesh, and the needle points of the discharge needles face the metal mesh ; Projection of the nth level discharge needle to the nth level needle tip projection point of the n+1th level metal mesh and the n+1th level discharge needle projected to the n+1th level n+1th level metal mesh Dislocation distribution of level pinpoint projection points; where, n is a natural number greater than 0. The arrangement position of the discharge needles in the upper discharge module and the arrangement position of the discharge needles in the next stage are misaligned in the projection direction. On the one hand, the discharge of the next stage has little influence on the resistance of the airflow, and on the other hand, the airflow in the space The corona discharge acceleration is alternately carried out at each position of the cross section to achieve a more uniform distribution of wind speed, and to improve the air supply speed, air supply volume and air supply efficiency of the multi-stage ion air supply module.

Description

technical field [0001] The invention relates to the technical field of ion air supply, in particular to a multi-stage ion air supply module. Background technique [0002] At present, as a unique air supply system, corona discharge ion air supply technology has become a technology with great market potential and good application prospects due to its simple structure, no noise, and air purification effect. It is a hot research direction of domestic and foreign researchers. The generation of ion wind in the prior art originates from the principle of corona discharge: due to the effect of high voltage, the electric field strength near the needle electrode is extremely high, which causes a large number of air molecules in the area to be ionized, while the electric field outside this area is weak , no ionization process takes place. Under the action of the electric field, the charged particles move directionally, and collide with uncharged neutral particles during the movement, ...

Problems solved by technology

In actual use, in order to obtain a higher wind speed, it is usually achieved by using a multi-stage ion wind acceleration method. However, due to structural limitations, the ion wind generated by the upper-level electric field will be affected by the next-level electric field after moving to the next-level electric field. The influence of the electric field structure produces a certain wind resistance, and, affected by the uneven distribution of the electric field, the wind speed of the final output ion wind is uneven
