Abstract

The utility model relates to a static dust catcher for air conditioners and air interchangers, which makes use of the force of an original fan of the air conditioners. A discharge electrode is formed by a negative pole of a high-pressure electrostatic generator, which is connected with a metal internal sleeve (5), a positive pole is formed by earth contact of a purifying grating (9), and thus an equipotential discharge circuit is formed. Air uniformly enters into a high-pressure electrostatic field through a vent hole (6) at the end surface of the metal internal sleeve (5) after the air is compressed by a pump (3). Dust particles in the air carry about negative electricity through the effect of the high voltage electrostatic field, and are absorbed on a purifying grating (9) after expanded and diffused. The utility model has the advantages of 100% dedusting efficiency, small size and low cost, and can be conveniently matched with the air conditioners and the air interchangers.

Description

Cottrell dust catcher for air conditioner and air interchanger

The utility model is the electrostatic precipitator of a kind of air conditioner, ventilator, belongs to the further improvement to existing common air-conditioning machine, ventilator electrostatic precipitator.

Existing common air-conditioning machine, ventilator, the general employing is provided with a basket strainer at its air outlet place, its weak point is that this basket strainer is to airborne dust, adsorptivity is poor, dust removing effects is bad, be unfavorable for indoor sanitation and hygiene, and necessary regular cleaning basket strainer, the dismounting cleaning operation is pretty troublesome.

The CN92227911 patent adopts the high-voltage electrostatic field discharge loop, and the air-flow that charged corpuscle is moved formation is used as the power that air flows, and makes air pass through the high-voltage electrostatic field, reaches the purpose of dedusting, and its weak point is:

1, HV generator power hour, only can make the fine motion of purifier ambient air, the air-flow that wants to utilize electron stream to form is used as power flows air, reach the purpose of dedusting, must strengthen the power of HV generator, for the bedroom, just exist unsafe factor, energy consumption is too big simultaneously.

2, the negative pole of HV generator is connected with the discharge barrier, its anodal formation discharge loop that is connected with the control of dust grid, and this direct discharge loop, on fire easily, have an accident, influence safe in utilization.

The purpose of this utility model be to avoid the deficiency of above-mentioned background technology and provide that a kind of energy consumption is little, economize on electricity, safe and reliable, volume is little, good dedusting effect, with air conditioner, ventilator can matching used air conditioner, the electrostatic precipitator of ventilator.

The purpose of this utility model can reach by following measure: the negative electrode with HV generator is that discharge electrode, anode are the air conditioner of dust collecting electrode composition discharge loop, the electrostatic precipitator of ventilator, it is characterized in that: the blow vent place of air conditioner, ventilator has horn-like gas cylinder to be communicated with insulation sleeve, inner metal sleeve is arranged in the insulation sleeve, inner metal sleeve connects the negative pole of electrostatic high-pressure generator, at least one passage is arranged on the one end, the purification grid ground connection that is positioned at insulation sleeve gas outlet end is as positive pole, is made of one deck metal perforated plate at least.

The purpose of this utility model can also reach by following measure: an end of gas cylinder has blow vent driving fit cover; The insulation sleeve that is communicated with gas cylinder is a circular cone shape, and the cover inwall has a circular cone shape inner metal sleeve; The uniform passage of arranging on one end face of inner metal sleeve; Purify grid and be made up of metal perforated plate more than two layers, gapped between each layer, the passage on each layer orifice plate is staggered mutually, and forms curved gas channel.

Description of drawings:

The structure chart that Fig. 1 is used in the air conditioner exhaust ports for the utility model

The structure chart that Fig. 2 is used in air conditioner air inlet place for the utility model

The utility model is described further below in conjunction with accompanying drawing:

As shown in Figure 1: the exhaust outlet of air conditioner (1) is located, having blow vent driving fit cover (2) to connect horn-like gas cylinder (3) is communicated with insulation sleeve (4), insulation sleeve (4) inwall is fixed with cover (5) in the frustum of aluminum metal thin-walled garden, 6 passages (6) are arranged on the air inlet end face of inner metal sleeve (5), and be connected with the negative pole of HV generator (8) by high pressure copper core cable (7).Purification grid (9) ground connection that is positioned at insulation sleeve (4) gas outlet end is as positive pole, constitute by three layers of detachable metal perforated plate, gap between each layer metal perforated plate is 2mm, and the passage on each layer metal perforated plate is staggered mutually, and forms curved gas channel.

During use, air conditioner is started working, connect the power supply of HV generator (8), the output voltage of HV generator is 5 kilovolts～50,000 volts, output current is 20 microamperes～200 microamperes, its negative pole is connected with cover (5) in the frustum of aluminum metal thin-walled garden becomes discharge electrode, purify grid ground connection and form discharge loop as positive pole, utilize the blower fan power of air conditioner, after air compressed in gas cylinder (3), passage (6) by aluminum metal cover (5) end face is sent in the high-voltage electrostatic field equably, the dust in air particle is subjected to the effect of high-voltage electrostatic field, all is with negative electricity, expands behind the cover (5) in aluminum metal, diffusion, all be cleaned grid (9) absorption behind curved gas channel, in like manner mushroom also is adsorbed.

This electrostatic precipitator is except can being used with it in the exhaust ports of above-mentioned air conditioner, can also be used with it at the air inlet place of air conditioner, gas cylinder this moment (3) is connected on the air inlet (10) of air conditioner by driving fit cover (2), with the dedusting of air elder generation and then enter air conditioner, still can reach good purifying and dedusting effect, as shown in Figure 2.

The utlity model has following advantage:

1, the negative pole of employing HV generator is connected with cover (5) in the aluminum metal becomes discharge electrode, purifies grid (9) ground connection as positive pole, forms the equipotential discharge loop, and it is safe, nothing harm.

2, utilize the original blower fan power of air conditioner to carry air cleaning, can save electric energy, reduce power consumption.

3, dedusting structure is simple, reasonable, after air compressed in gas cylinder, passage by aluminum metal cover end face is sent in the high-voltage electrostatic field equably, the dust in air particle is subjected to the effect of high-voltage electrostatic field, all be with negative electricity, after expanding behind the cover in aluminum metal, spreading, be cleaned grid (9) absorption, the udst separation efficient of its air can reach 100%.

4, purify the curved air duct of grid, increased the area of dust suction, prolonged the time of regularly cleaning, reduced the number of times and the amount of labour of cleaning, dismantle easily and clear up.

5, volume is little, and the cost cost is low, can with the supporting easily use of air conditioner, ventilator, reduce new investment, help promoting the use of.
