The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, air duct type air cleaning unit described in the utility model, it comprises housing 1, wind pushing mechanism 2 and control of dust purification assembly, wind pushing mechanism 2 is arranged at respectively on the housing 1 with the control of dust purification assembly, housing 1 is provided with air outlet 3, and air outlet 3 is connected with air channel 4.Wherein, the control of dust purification assembly comprises corona anode 5, corona emitter 6 and power supply 7, power supply 7 is arranged on the housing 1, corona anode 5 is electrically connected with power supply 7 respectively with corona emitter 6, this power supply 7 is preferably the power supply into the 10000-30000 volt, specifically can be the positive high voltage power supply, negative high voltage power source or alternating-current pulse power supply, wherein the positive high voltage power supply is applicable to the occasion use of low-ozone amount, negative high voltage power source is suitable for general conventional place to be used, the alternating-current pulse power supply then is applicable to the occasion use that the ratio resistance of space particle is bigger, in addition, the power supply 7 that the technical program adopted also can in press or or low pressure, though voltage is lower, as long as the electric field existence, also can realize follow-up dust collecting effect (certainly, integrated effect does not have the good of high pressure certainly).And corona emitter 6 is arranged on the air channel 4, and corona anode 5 is provided with around wind pushing mechanism 2 and is connected with air channel 4.
Yet wind pushing mechanism 2 is an axial-flow fan among the embodiment of the present utility model, and as Fig. 1, Fig. 2 and shown in Figure 3, axial-flow fan is installed on the housing 1, and air channel 4 is made as the circular arc type air channel and centers on the axial-flow fan setting, and air channel 4 is connected with air outlet 3.Equally, corona anode 5 makes corona anode 5 as the collecting plate setting around air channel 4 and around axial-flow fan.Because corona anode 5 is installed with corona emitter 6 is independent respectively, corona emitter 6 corresponding corona anodes 5 and independently being installed on the air channel 4.According to actual conditions, this corona emitter 6 can the whole air channel 4 of all standing on or cover on the local air channel 4, and corona emitter 6 covers whole air channels 4 equally or covers on the local air channel 4, after corona anode 5 and corona emitter 6 are switched on, corona anode 5 forms charging area and accumulation area with the zone at corona emission 6 places, this charging area and accumulation area can cover whole air channel 4 or part air channel 4, thereby obtain bigger dust-collecting area, therefore improve purification efficiency greatly.
Promptly, axial-flow fan changes air and flows, air channel 4 tools guiding and change wind direction, because the effect of axial-flow fan, certain horizontal blast has been born in air channel 4, wind-force and electric field force are equidirectional or the less acute angle of angle, when the big more then blast of wind flow big more, the distinguished and admirable turbulent flow that on air channel 4, forms, make contaminated air and maximized contact of air channel 4 tools, and can make contaminated air be far longer than the time of passing through electrostatic dust-collecting device through the time in air channel 4, thereby make airborne pollutant have more time at the corona ionized region charged and on corona anode 5 deposition, and then under lower voltage condition, also can allow airborne dirt fully contact with corona anode 5 with corona emitter 6, and make the efficient of control of dust higher, cut down the consumption of energy simultaneously.
In addition, as Fig. 4 and shown in Figure 5, another embodiment of the present utility model and above-mentioned difference are: wind pushing mechanism 2 is aerofoil fan, aerofoil fan is arranged on the housing 1, air channel 4 is made as the straight barrel type air channel and is connected with corona anode 5, and corona anode 5 threaded shaft flow fans are provided with, and corona anode 5 is connected as a single entity with corona emitter 6, corona emitter 6 is arranged on the air channel 4, and corona emitter 6 covers on whole air channel 4 or the local air channel 4.Like this, make contaminated air pass through aerofoil fan and import air channel 4, during air channel 4, the contaminated air process is in the corona place that is provided with corona emitter 6, the corona place produces ionization under the effect of high voltage electric field, make through the contaminant particle in the contaminated air is negative here to go up electric charge and collect on the corona anode 5 of opposite electrode.Because it is longer that whole air channel 4 as corona anode 5 and control of dust, makes through 4 times of air channel, there is the sufficient time to deposit for airborne pollutant, thereby obtains higher purification efficiency.
In addition, another embodiment of the present utility model and above-mentioned difference are: wind pushing mechanism 2 is cross flow fan.
According to above-mentioned, no matter be axial-flow fan, aerofoil fan or cross flow fan, difference to some extent in the design of air channel 4, but its wind cutting characteristic is consistent, by design the pollutant collection is attached on the air channel 4 equally enlarges dust-collecting area and obtains higher purification efficiency.
Moreover, the utility model is in order to reduce windage, the sidewall of corona anode 5 is five metals plate, electroplating plastic plate, metallic film or wire netting, and corona emitter 6 adopts the less needle-like of windages, wire, zigzag, star-like, barb type or fish bone well structure, and, in order to clean conveniently, the utility model can be covered with the opening device of opening bonnet behind housing 1, thus the convenient pollutant that cleans body.
In addition, because the corona emitter 6 that produces emission of ions has been installed in the air channel 4, the static of its generation, electromagnetic wave can exert an influence to the operation of motor, therefore can add screening arrangement on the surface of motor and do ground connection processing, perhaps the wind wheel in the wind pushing mechanism 2 are carried out antistatic and handle.
