Background technology
The Main Function of ion blower is to destatic, and prevents that static from polluting and destroying.Ion blower can produce a large amount of electric currents with positive charge and negative electrical charge, neutralize on object with electric charge.Such as: when body surface institute is charged while being negative electrical charge, it can absorb the positive charge in air-flow; When body surface institute is electrically charged while be positive charge, it can absorb the negative electrical charge in air-flow, thereby the static on body surface is neutralized, and reaches the object of elimination static.Therefore, ion blower is that electronic circuit board is produced, the necessary equipment of assembly shop.But, when destaticing, can not introduce the pollutants such as dust, otherwise can cause the series of problems such as electronic circuit board heat radiation, insulation; Dust also can pollute emission needle, the effect that affects air ionization and destatic simultaneously.Therefore ion blower is necessary design and is equipped with special dust removal and filtration structure.
At present, the filtration of ion blower, dedusting structure adopt, at air intake place, one or more layers sponge, nonwoven fabrics etc. are set, after air filters by one or more layers sponge or nonwoven fabrics etc., then the cleaned air (" cleaned air " refers to " air that amount of dust content is less ") that is ionized, forms with positive charge and negative electrical charge blows out.Below by the air inlet place at many ion blowers, different filtrations, dedusting structure are set, the effect that destatics of existing ion blower is tested.Technique requires the effect detection standard that destatics of ion blower to be conventionally: the adsorption electrostatic of object surface must be reduced to below 200V from 1000V in 3s.
1, the air intake place of ion blower does not arrange and filters sponge: in the scope apart from ion blower air outlet 30cm, it is 1.5～2.6S that the adsorption electrostatic of object surface drops to the time required below 200V from 1000V.
2, add 1 standard configuration at the air intake place of ion blower and filter sponge: in the scope apart from ion blower air outlet 30cm, air output trace weakens, and it is 3～5S that the adsorption electrostatic of object surface drops to the time required below 200V from 1000V.
3, add 2 standard configurations at the air intake place of ion blower and filter sponge: in the scope apart from ion blower air outlet 30cm, air output obviously diminishes, and it is 8～11S that the adsorption electrostatic of object surface drops to the time required below 200V from 1000V.
4, add 1 sponge of strengthening density and thickening at the air intake place of ion blower: in the scope apart from ion blower air outlet 30cm, air output is very little, the adsorption electrostatic of object surface still rests on 400V left and right from 1000V electrified body blows 30S.
5, add 1 serious filtration sponge dusty at the air intake place of ion blower: in the scope apart from ion blower air outlet 30cm, air output obviously diminishes, and it is 7～10S that the adsorption electrostatic of object surface drops to the time required below 200V from 1000V.
Can be found out by above-mentioned test data: do not arrange and filter sponge, can meet the effect detection standard that destatics of existing technological requirement, can make the problem such as contamination by dust electronic circuit board, pollution electric discharge emission needle but be exposed to for a long time in air; Adding 1 air output filtering after sponge can weaken but affect little by trace; When the air output that can obviously reduce after sponge increase in density; Adding its air output of 2 layers of sponge (being also equivalent to strengthen density) weakens a lot; Sponge increase in density is just equivalent to the long-pending full dust of sponge, and the same air output can weaken, and the little words of air output can obviously affect the effect that destatics of ion blower, cannot meet the use needs of streamline.Above-mentioned " air output " refers to the air mass flow with positive charge and negative electrical charge producing after ionization of ion blower air outlet output.This shows, prior art exists the improved demand of above-mentioned technical problem.
