Description

The modified air cleaning unit

Technical field

The utility model relates to a kind of modified air cleaning unit, relates in particular to a kind of device that is used for the building air cleaning, and particularly suitable is to the device of the positive negative oxygen ion of indoor injection to indoor air purification.

Background technology

In the building air purification field, often adopt the high direct voltage electrostatic technique to come smoke abatement, dedusting and kill bacteria (virus) to reach the purpose of pure air.The monopolar high-voltage electrostatic field that uses at present in this field is generally continued to use the principle of boiler flue dedusting and is made its microminiaturization, the subsequent arrangement dust collect plant.To killing of bacterium is to realize by the ozone that this high voltage electrostatic device produces when the gas ionization, after the bacterium that depends on dust is summed up in the point that in the dust arrester, also can reduce the bacterium that swims in the interior space.But as adopting the above-mentioned high voltage electrostatic device that has dust collect plant will produce great windage, destroy original running status, this also is the reason that people are unwilling to accept this device.

The application number that the applicant formerly proposes is in " air cleaning unit " patent application of 200310108137.0, disclose a kind of device that utilizes static to carry out air cleaning, this air cleaning unit, form by shell and installation ion generator in the enclosure, ion generator is powering up generation high-voltage electrostatic field, back, the negative pole of high-voltage electrostatic field is made up of a plurality of continuous woven wires that have circular section, just very be in the wire of the position of center line of circular section, the wire normal direction is the flow through direction of electrostatic field of processed air.Above-mentioned air cleaning unit is compared with existing apparatus, because electrostatic field version has uniform electric-field intensity, so purification efficiency is higher, this electrostatic field adopts the wire mesh structure form to determine it to have very considerable ventilation rate simultaneously, windage is lower, can satisfy in the central air conditioner system requirement to air quantity fully.

But in practice, when especially in the building of central air-conditioning, using, because the high-voltage electrostatic field that above-mentioned " air cleaning unit " can only produce the one pole ion, as a system, its requirement to air cleaning roughly is divided into following 3 points with regard to the interior space: (1) is reduced in the appreciable various smells of indoor people; (2) reduce people's pellet in the room air; (3) by reducing the airborne bacterium that swims to reach the demand for security that reduces airborne peculiar smell (organic volatile smell) and satisfy public arena air hygiene; Therefore depending merely on one pole ion high-voltage electrostatic field can't satisfy above-mentioned requirements, and for this reason, the applicant proposes following improvement project to patent application formerly.

The utility model content

The utility model purpose is to provide a kind of modified air cleaning unit, be meant a kind of positive and negative oxonium ion generator that produces bipolar ionization especially to purify air effectively, reach the effect of eliminating airborne peculiar smell, the airborne pellet of minimizing and killing the airborne bacterium that swims.

For achieving the above object, the modified air cleaning unit that the utility model provides, comprise shell, described shell comprises an air inlet and an air outlet, and one be arranged on the oxonium ion generator between the described air inlet and described air outlet in the described shell, and described oxonium ion generator comprises the woven wire of a plurality of open circles cylinders that connect as one and the wire that Duo Gen is separately positioned on each described woven wire center longitudinal axis line position; It is characterized in that: described woven wire is by lead ground connection, and each described wire is connected, forms bipolar electrostatic field with the negative or positive electrode of dc source respectively.

Preferably, described wire is connected with the negative or positive electrode of dc source with interval mode.

Preferably, described wire is connected with the negative or positive electrode of dc source in the class interval mode.

Preferably, described woven wire linearly or be arc shaped and arrange and to connect as one.

Preferably, also comprise a dust arrester, described dust arrester is arranged on the air outlet place of described shell.

Modified air cleaning unit provided by the utility model, owing to adopted the positive and negative oxonium ion generator of bipolar electrostatic field, can eliminate peculiar smell in the air preferably, as the smell of machine volatile matters such as smoke, stink, reduce airborne pellet and the effect of killing the airborne bacterium that swims.

Be described further below with reference to the technique effect of accompanying drawing, to understand the utility model fully design of the present utility model, concrete structure and generation.
