Description
Technical field
The invention belongs to the electrostatic precipitation of technical field of air purification more particularly to a kind of more micron pore arrays of V-type with remove
Wet system.
Background technique
With the continuous promotion of scientific and technological level, the requirement of laboratory and family for air quality is higher and higher.In gas
Wait moist season, the clothes in wardrobe be easy to appear it is moist, mouldy, have the problems such as peculiar smell, be easy to cause the numerous of germ for a long time
It grows and propagates, bring inconvenience to people's lives.When relative humidity is greater than 85%, it is easiest to go mouldy, linsey-woolsey storage
It is required that: 40% ﹣ 60%RH；Simultaneously in unclean wardrobe, it is heavy in shoulder and collar that the long-term storage of clothes will lead to dust
Product, will affect the comfort level of clothing arranged and worn the clothes.Fine particle content is also that cultural relics in the collection of cultural institution saves, is electric in humidity and air
Important references factor in the environment such as sub- product operation, laboratory operation will have a direct impact on relevant physics, chemistry and biology and make
With.The variation of relative humidity can generate different degrees of influence to the preservation of most of cultural relics in the collection of cultural institution.Moisture in air can be straight
It connects and is transmitted with the moisture in historical relic, and higher relative humidity can accelerate the corrosion of historical relic, and be conducive to microorganism
The growth of mould.And relative humidity also has a major impact electronic product operation, relative humidity is excessively high to cause metal material
Burn into reduces the insulation performance of dielectric material, and product can fail or damage when serious；Relative humidity is too low, also easily causes electronics

With liquid dehumidifying technology.Dehumidification by condensation is air to be reduced to dew point or less the hydrogenesis in air is come out.Currently, big
Most air-conditionings remove wet process using this, but the disadvantage is: energy consumption is high, operating cost is high, noise is big, design is complicated, poor reliability
Deng；Solid, liquid dehumidifying technology are that solid dehumidifying agent or liquid desiccant is used to adsorb the moisture in air to reach dehumidifying
Purpose.Since solid dehumidifying agent does not have mobility, the regeneration temperature needed is higher, also there is biggish energy consumption；And liquid removes
Humectant is due to can achieve preferable Mass and heat transfer effect with mobility, and the regeneration temperature needed is lower, and energy consumption is relatively low,
But currently used liquid desiccant is mainly the solution such as lithium bromide, lithium chloride, calcium chloride, has certain corrosivity, no
It reduced by only the service life of dehumidification equipment, and may cause the corrosion to product.It is directed to local space at present, still lacks a kind of gram
Above-mentioned technical deficiency is taken and at the same time playing the device of dehumidifying with dedusting double effects.

And drip in the hole 12 of back taper, waste liquid is discharged in the U-tube 13 of the variable cross-section in liquid collecting module.
When the air detection meter in control module detects that the fine particle content in air is less than the value of setting, show
Fine particle in local space removes substantially, and control module closes the miniature peristaltic pump 14 and negative high voltage hair of its connection later
Raw device, into single link that dehumidifies, remaining water mist and steam are removed in main local area air, in V-type channel, due to
Uneven uniform electric field is formed by between metal tip 9 and hydrophilic metal conducting wire 4 makes air ionization go out a large amount of high energy electrons,
In motion process with the micro droplet collision in air-flow and be attached to its surface, when by V-type channel with metal tip, in electricity
Under the action of field force, charged microlayer model is poly- simultaneously to hydrophilic metal conducting wire 4, and attached thereto, and central hydrophilic metal conducting wire 4 adheres to
After water under gravity, least significant end is flowed to along conducting wire, and dripped in the hole 12 of back taper, the change in liquid collecting module
Waste liquid is discharged in the U-tube 13 in section；In V-type channel tail portion, hydrophilic conducting wire 4 is connected with metallic sieve 10, and is grounded, gold
Belonging to sieve can reach the purpose for neutralizing extra high energy particle and plays the role of auxiliary interception fine particle and moisture；Tail portion goes out
Mouthful place small axial flow fan 11 can control the air velocity in package unit, when air velocity stablize in a steady state value, the whole series
The dedusting effect on moisture extraction of device is up to optimal.
Above embodiments are merely to illustrate design philosophy and feature of the invention, and its object is to make technology in the art
Personnel can understand the content of the present invention and implement it accordingly, and protection scope of the present invention is not limited to the above embodiments.So it is all according to
It is within the scope of the present invention according to equivalent variations made by disclosed principle, mentality of designing or modification.
