Description

Electrostatic precipitator and airhandling equipment Technical field

The present invention relates to airhandling equipments, and in particular, to electrostatic precipitator, moreover, it relates to use the airhandling equipment of electrostatic precipitator.

Background technique

Atmosphere polluting problem has increasingly been highlighted in today's society, seriously endanger the health of people, in order to cope with worsening atmosphere polluting problem, all kinds of airhandling equipments are widely used in family, office building, hospital, school etc., and wherein aeration device is using a kind of airhandling equipment more stronger than wide, practicability.Product is mainly based on central fresh air system in fresh air industry at present, and in addition to this, wall-hanging, cabinet type new blower, the new blower of wall-penetrating type are also applied more.

Central fresh air system includes the host and blast pipe and discharge pipe for being installed on indoor top, and foul indoor air is discharged indoor through discharge pipe, and outdoor fresh air is sent into interior through blast pipe after the main emission controls by improving combustion of fresh air.General setting blower and filter screen, blower include air-introduced machine and exhaust blower to realize two-way circulating for air-flow inside fresh air host, some further include portion temperature exchange and the adjusting air humidity that total-heat exchanger realizes room air and outdoor air.

Wall-hanging and cabinet type new blower are that the components such as blower and strainer are integrated in a machine to be formed on host, which is typically mounted at interior, and by being connected into and out of pipeline with outdoor, general pipeline is shorter, is hidden in invisible in wall.Blower is divided into air-introduced machine and pressure fan, air-introduced machine introduces foul indoor air discharge outdoor by the air port around host shell when work, and pressure fan is sent into after filter assemblies (generally multistage strainer) indoor by admission line introducing outdoor fresh air.In addition, higher wall-hanging is configured and cabinet type new blower generally installs total-heat exchanger additional, to realize portion temperature exchange and the adjusting air humidity of room air and outdoor air.

The new blower of wall-penetrating type, it is generally mounted on wall or glass, new blower is set to be placed in wall or inside glass by punching (general diameter 15cm or more) on wall or glass, it introduces outdoor air by inner fan and is sent into interior by filter assemblies (strainer), this new blower of wall-penetrating type is generally the one-way flow of air-flow, some products realize a degree of intermittent indoor exchanging with outdoor air by controlling the positive and negative rotation of fan.

Above-mentioned center fresh air system, needs to install a large amount of blast pipes and air-exhausting duct, destroys family's interior trim, greatly occupancy domestic space.For wall-hanging and cabinet type new blower, although saving ventilation shaft to a certain degree, it takes up space larger, and machines cumbersome, power is also larger, consumes energy excessively high, uses very uneconomical.The new blower of wall-penetrating type is generally filtered by strainer, the low efficiency once filtered, it is difficult to meet the requirement of fresh air, and due to needing integral installation in wall hole, excessively high for the diametric requirements of wall hole, practicability reduces, and seriously affects the selection of consumer.

In addition, above-mentioned center fresh air system, wall-hanging and cabinet type new blower are other than use strainer is as airhandling equipment, it is some of also to use electrostatic dust collection equipment as airhandling equipment, but these electrostatic dust collection equipments are confined to the natural mode of electrostatic field formation, it uses the plate of traditional parallel interval opposed type to form electrostatic field, lead to the bulky of these new blowers, occupied space is excessive, and air stream to dedusting is straight quickly through, it is lower to frequently result in air cleaning efficiency, the New atmosphere quality of introducing is often inferior, influence human health, this leads to the new blower using these electrostatic dust collection equipments, and acceptance is relatively low on the market.In addition, leading to these new blowers, there are biggish security risks using the new blower of electrostatic dust collection equipment there is also some influence human healths, the long-term indiscoverable recessive hazard factor of those skilled in the art.

More seriously, the generally existing defect having a single function of the new blower of the above-mentioned type, only has the function of air outer circulation, in the case where outside air serious haze, the work load of new blower filter assemblies is not only aggravated, it is easily damaged it, and is even not so good as indoor original air quality from external suction and by filtered air quality.In view of this, there is also the new blowers with interior circulatory function of some relative coarseness in the prior art, such as, some new blowers are in order to form interior circulating working mode, interior circulation pattern and outer circulation mode are formed respectively relatively independently using two blowers, this does not overcome the above-mentioned existing defect of existing new blower not only, and causes new blower fan volume huger, structure is more complicated, and air duct is laid with more many and diverse.In addition, there are also directly open up an indoor air inlet on some wall-hangings and cabinet type new blower indoors body, indoor air inlet is selectively blocked by the switching cover board of internal body or connects the external air inlet of external intake stack, to realize the switching of outer circulation operating mode and interior circulating working mode, but, there is no the essence for changing wall-hanging and cabinet type new blower for this structure type, it is intrinsic, and to occupy the interior space big, it is heavy, there is no change for the excessively high defect that consumes energy, more seriously, this coarse way that indoor air inlet is directly opened up in wall-hanging and on the indoor body of cabinet type new blower, it will lead to and thunder, filtration members damage, the major defects such as air endless loop.Specifically, since the inlet chamber of wall-hanging and the indoor host computer of cabinet type new blower is generally large, directly indoor air inlet is opened up on host indoors, indoor air inlet is closer apart from blower, room air through blower suction can be buffered unlike outside air inlet via external intake stack, in its inlet chamber for directly entering the room host at a high speed, indoor body is caused to tremble, even thunder, simultaneously because room air via blower powerful suction without buffering high-speed impact filtration members, cause filtration members to be easily damaged, good filtration can not be played.Once filtration members are damaged, filtration members can not effectively act as the effect of limitation air outlet velocity, the flow velocity of air inlet and the outlet tends to be close, it verifies, easily form the endless loop of room air in the subrange around host indoors at this time, i.e. the interior circulating working mode of wall-hanging and cabinet type new blower can not effectively purify the air of a room substantially at this time, be in invalid state.

The drawbacks described above of new blower, it has been formed and has restricted the technical bottleneck that new blower further develops, some hazard factor those skilled in the art are unaware that there are hidden troubles so far, specifically how make new blower on the basis of having both inside and outside circulating working mode, it is effectively saved the interior space, working performance is well reliable, has become the technical problem of this field.

As shown in Figure 14, Figure 15, present invention firstly provides a kind of electrostatic precipitator, including the dust leg 5 with annular cross section and along the more electrode wires 21 being spaced apart of cross circular section circumferential direction of dust leg 5, electrode wires 21 are axially extending along dust leg 5, more Root electrode wires 21 be arranged to the radially spaced concentric ring shape of dust leg 5, one of electrode wires 21 and dust leg 5 are positively charged, and another one is negatively charged.

Existing conventional electrostatic precipitation structure is board-like discharge electrode, muti-piece discharge electrode and muti-piece collecting plate are in grid-like successively arranged for interval in rectangle peripheral frame, and entire electrostatic precipitation structure is arranged in the indoor body of airhandling equipment, occupy the intracorporal limited installation space of indoor unit, and increase the weight of indoor body, cause volume, weight big, not easy to install, demolition and maintenance.And electrostatic precipitator of the invention may be directly applied in ventilation shaft, be dusted in ventilation shaft, mounting arrangements mode is novel.Specifically, using the structure for the electrode wires 21 arranged in dust leg 5 and its pipe or outside pipe, dust leg 5 can be integrally embedded in air duct, cellular construction is compact, deft design, circumferential electrostatic field can be formed, is enabled and is charged and effectively collected by dust leg, better dust removal effect by the dust in the air-flow in the pipe of dust leg 5 or outside pipe.In addition, this electrostatic precipitator can be applied in all types of air ducts of various airhandling equipment, effectively mitigate the volume and weight of indoor body.

To form reliable and stable circumferential electrostatic field, so that the dust particle in the air-flow passed through can be charged effectively, to be collected by dust leg 5.In the present embodiment, the radical of electrode wires 21 is preferably 3~6, such as 4 electrode wires 21 circumferentially arranged at equal intervals.Wherein, the diameter of electrode wires 21 should be in 0.008~0.5mm, and the more detailed rules and regulations discharge effect of electrode wires 21 is better, but electrode wires 21 are high more being fine into this more, not easy to be processed and easy tension failure.Therefore, in the present embodiment, overall balance processing, cost and discharge effect, the diameter of electrode wires 21 are preferably 0.08~0.2mm.Electrode wires 21 should be straightened along axial direction, in order to avoid it is in electrical contact other components.The axial length of electrode wires 21 is preferably less than the length of dust leg 5, and the both ends of electrode wires 21 are fixed and the fixed position in both ends is without departing from the both ends of dust leg 5.In this way, facilitating charged dust can effectively be collected by dust leg 5.

There are in the case where outer tube, dust leg 5 can be used as inner tube, and electrode wires 21 may be arranged at outside dust leg 5, i.e., dust leg 5 collects electrification dust particle as inner tubal wall.But preferably, electrode wires 21 are arranged in dust leg 5, and dust leg 5 is used as outer tube, and when inner tube is not present in dust leg 5, the entire lumen of dust leg 5 is as air duct.For 5 memory of dust leg in inner tube, the local lumen (i.e. perimetrical lumen) in dust leg 5 can be used as air duct, and electrode wires are directly arranged in the air duct in dust leg 5.

Electrostatic precipitator of the invention may also include guide duct, and guide duct and dust leg 5 form radially spaced embedding tube, and the perimetrical lumen 6 between guide duct and dust leg 5 is formed as air duct, and electrode wires 21 are arranged in perimetrical lumen 6.At this point, guide duct and dust leg 5 inner and outer pipes, electrode wires 21 can be then arranged in the perimetrical lumen 6 of the two as air duct each other.In the present embodiment, dust leg 5 is used as outer tube, and guide duct is the inner tube 1 being embedded in dust leg 5, and the windward side closing of inner tube 1, material is thus formed annular passage, electrode wires 21 are arranged in annular passage.

Wherein, more electrode wires 21 are equidistantly spaced from along the circumferential direction of inner tube 1.Electrode wires 21 are generally proximal to the periphery wall setting of inner tube 1, the cylindrical diameter that more electrode wires 21 are surrounded should be no more than the 80% of the interior diameter of dust leg 5, and radial distance of the electrode wires 21 apart from dust leg 5 is not less than 1cm, generates discharge breakdown to prevent hypotelorism.Meanwhile the cylindrical diameter that is surrounded of more electrode wires 21 should be greater than the outer diameter of inner tube 1, and 40% of the interior caliber not less than dust leg 5.Otherwise, the radial spacing for being formed by circumferential electrostatic field is excessive, then charged dust particle to move radially distance big, it is not easy to effectively collected.

Electrostatic precipitator of the invention further includes high pressure generator 16, and one of electrode wires 21 and dust leg 5 are electrically connected the anode of high pressure generator 16, and another one is electrically connected the cathode of high pressure generator 16.When the parameter selection of high pressure generator 16, it is higher to be considered as the more high then air-flow purification efficiency of discharge voltage, but can also generate more ozone.By testing and comprehensively considering, the discharge voltage of high pressure generator 16 is preferably 5~9KV, more preferably 8KV or so, and purification efficiency and ozone production quantity are acceptable at this time.High pressure generator 16 can be placed in outside the lumen of dust leg 5, can also place wherein.For example, high pressure generator 16 is built-in in inner tube 1 when inner tube 1 is isolation material pipe.

In addition, deflector 4 is axially extended in the shape of a spiral to form helical duct as shown in figure 5, being also in particular provided with deflector 4 in perimetrical lumen 6, referring to Figure 10, electrode wires are axially across each deflector 4.In this way, in the case that then the volume of the perimetrical lumen 6 in dust leg 5, length limit, by forming helical duct in perimetrical lumen 6, that is helical form air duct, the flow time of air-flow can be greatly prolonged, that is, increases the clarification time of electrostatic precipitation, obtains more preferably dust removing effects.Moreover, the presence of deflector 4 can also keep out the impact of air-flow, mitigate the blower burden of indoor unit, reduces complete machine and tremble.Especially, when air-flow flows in helical duct, charged dust particle will be got rid of by centrifugal force to dust leg 5 with the flowing of eddy flow, it is easier to is collected.

To fix convenient for the installation of deflector 4 and electrode wires 21, flow guide sleeve 3 is introduced, helically foliaceous is installed on the periphery wall of flow guide sleeve 3 deflector 4, and flow guide sleeve 3 is convenient to be sheathed in inner tube 1.Wherein, dust leg 5 is preferably conductive metal pipe, and flow guide sleeve 3 and deflector 4 are preferably isolation material, to avoid high pressure electric shock or conductive dangerous.It is anticreep and be easily installed for this purpose, can also be set with insulation outer tube outside dust leg 5, it will also specifically address below.

The above-mentioned electrostatic precipitator that circumferential electrostatic field can be formed can be applied in any airhandling equipment, it is directly embedded into the air hose (i.e. tracheal tube) for being installed on airhandling equipment, to obtain dust removing effects, this is substantially distinguished from the indoor arrangement of existing electrostatic precipitator.

Electrostatic precipitator due to being arranged in air hose inevitably ionizes out ozone in electrion dust removal process, and it is necessary to effectively be removed when flowing through indoor body thus.For this purpose, being particularly provided with ozone filtering module 14 in indoor body, the outlet air end of the air hose equipped with electrostatic precipitator is aligned ozone filtering module 14, referring to Fig. 1 and Fig. 5.Meanwhile airhandling equipment includes air suction device 15, the outlet air end of air hose is located at the side of ozone filtering module 14, and air suction device 15 is located at the other side of ozone filtering module 14.Air suction device 15 in indoor body can provide suction power, allows flow through the air duct in air hose, and then pass through ozone filtering module 14, carries out the secondary cleaning treatment of air-flow.To encapsulate indoor body and facilitating the suction of air suction device 15, airhandling equipment further includes the outer cover 17 around air suction device 15 and ozone filtering module 14.In embodiment of the present invention shown in Fig. 1, air suction device 15 is preferably aerofoil fan, axial to aspirate air.

To remove the ozone ingredient in the air-flow after electrostatic precipitation, the surface of ozone filtering module 14 can be formed with the surface covering decomposed for catalysis ozone.Simultaneously, have the surface area of surface covering without generating excessive resistance to air-flow to expand, ozone filtering module 14 is preferably the honeycomb metal structure with multiple honeycomb holes, air-flow with ozone ingredient flows through ozone filtering module 14 along many honeycomb holes, resistance is small, so that the processing capacity of airhandling equipment does not reduce.Meanwhile the surface area of the honeycomb metal structure with multiple honeycomb holes is sufficiently large.It should be noted that the end face size of ozone filtering module 14 should be able to cover the pipe end end face of tracheal tube, so that the air-flow with ozone ingredient flowed out from air hose can be removed completely ozone by ozone filtering module 14.For this purpose, airhandling equipment may include the multistage ozone filtering module 14 for being arranged in the outlet air end of air hose, multistage ozone filtering module 14 arranged stacked spaced reciprocally so that reach meet as defined in except the requirement of ozone rate.

In Figure 14, ozone filtering module 14 includes electronic control module 141 and ozone sensor 142, the air side of ozone filtering module 14 is arranged in detect ozone concentration in ozone sensor 142, and electronic control module 141 is configured to compare the upper threshold value of the ozone concentration signal detected of ozone sensor 142 and set ozone concentration and issues alerting signal when judging that ozone concentration is exceeded.At this point, can be according to the ozone filtering module 14 that alerting signal more renews.

Below preferably, the present invention above-mentioned electrostatic precipitator and ozone filtering module 14 are applied in the air duct of various airhandling equipment, especially Two-way Cycle embeds in airhandling equipment and its system of wall hole formula, specifically, above-mentioned electrostatic precipitator is applied to Two-way Cycle and embeds in the wall pipe of wall hole formula airhandling equipment, thus expansion illustrates, the above-mentioned various effects in air duct of the invention, advantage will be more prominent, and effect becomes apparent from.

As previously described, to realize double working modes, and compact integral structure, it occupies little space, working performance is steadily reliable, and the present invention also provides a kind of novel air processing equipment, especially Two-way Cycles to embed wall hole formula airhandling equipment, the airhandling equipment includes air hose and is exposed to indoor indoor body, as shown in figure 17.Particularly, the present invention is formed with the Interior Space tracheae internal channel of the purification air hose internal channel that outdoor air passes through and room air circulation in air hose, and from blast pipe at random, air-exhausting duct etc. may be not present, complete machine structure is simple, compact, as shown in Figures 3 to 5.At this point, indoor body is equipped with the outlet of purification wind, indoor air inlet and air suction device 15.Wherein, air hose can be the common blast pipe of various airhandling equipment, but below in conjunction in the explanation of attached drawing, air hose is preferably the wall pipe being flush-mounted in wall hole.

Wherein, airhandling equipment further includes air duct switching device and air cleaning unit, air duct switching device for selectively uniquely conducting Interior Space tracheae internal channel or purification air hose internal channel, thus make airhandling equipment correspondingly switch operating in interior circulating working mode or air inducing operating mode；That is:

Under interior circulating working mode, room air enters the room air hose internal channel from indoor air inlet under the effect of air suction device 15 and is expelled to interior from the outlet of purification wind after air cleaning unit purifies；

Under air inducing operating mode, outdoor air enters purification air hose internal channel from the axially outer end (i.e. the paper right end of Fig. 1, Fig. 2, similar below) of air hose under the effect of air suction device 15 and is expelled to interior from the outlet of purification wind after air cleaning unit purifies.

After forming purification air hose internal channel and Interior Space tracheae internal channel in air hose, the circulation path of air-flow is longer, even if under the strong pumping effect of air suction device 15, air-flow also obtains comfort cushioning in the purification air hose internal channel in air hose or Interior Space tracheae internal channel, it is small to the impact of complete machine, it is mainly reflected in the air hose that wall-penetrating type is fixedly mounted impact even if generating, it is small to the impact endurance test shock of complete machine.

In addition, air suction device 15 in the embodiment of Fig. 1 is preferably single aerofoil fan, the purification wind outlet of airhandling equipment and aerofoil fan are axially aligned in the interior shaft end of air hose, this is because purification air hose internal channel and Interior Space tracheae internal channel are integrated in air hose, air stream outlet is all in the interior shaft end of air hose, thus only single blower need to be arranged in the interior shaft end of air hose, and the two fans structure of unconventional Two-way Cycle airhandling equipment, in other words, blower can share, so that structure integrated level is high.In addition, following also by what is addressed, due to purifying air hose internal channel and Interior Space tracheae internal channel compact Layout in air hose, air flow path is long, and air cleaning unit is also able to compact Layout.

To realize the purification air hose internal channel and Interior Space tracheae internal channel designing compact-sized, path length in air hose and can switch in due course, those skilled in the art are readily apparent that the form using built-in double parallel pipe or more in air hose, however this certainly will require the caliber of air hose big, can satisfy air quantity demand.To accomplish compact-sized and maximizing increase intake, embedded wall hole formula airhandling equipment of the invention uses the cannula structure including inner tube 1 and outer tube, any one of perimetrical lumen 6 between inner tube lumen and inner and outer pipes is purification air hose internal channel, i.e. outdoor air can enter inner tube lumen or perimetrical lumen 6 from the axially outer end of air hose, then flow out from corresponding interior shaft end.

At this point, the other of inner tube lumen and perimetrical lumen 6 constitute Interior Space tracheae internal channel or at least constitute a part of Interior Space tracheae internal channel.Since under double working modes, when purification air hose internal channel connection is to enter outdoor air, Interior Space tracheae internal channel needs to close, similarly, when Interior Space tracheae internal channel is connected to, purification air hose internal channel needs to close.At this point, in view of in the indoor air inlet setting under interior circulation pattern indoors body, thus relatively reasonable air duct arrangement is can only to enter then to wrap to interior shaft end outflow from the interior shaft part of air hose.Therefore, Interior Space tracheae internal channel may include the inner tube lumen and perimetrical lumen 6 of inner tube 1, the room air that indoor air inlet enters enters in air hose via the interior shaft end of one of inner tube lumen and perimetrical lumen 6, it then can enter the intracavitary of another one from axially outer end, preferably be flowed out from the interior shaft end of the another one.Not only process is longer in this way, but also either interior circulation or air inducing work Under operation mode, in air hose at least passage portion be room air and outdoor air share flow through place jointly, to also just facilitate the densification arrangement of air cleaning unit, need be only arranged in shared runner.

On this basis, to realize Interior Space tracheae internal channel and purifying the in due course switching of air hose internal channel, it is divided from the principle of work and power, air duct switching device should include two controllable switching valves, can open in due course to introduce the citation damper of outdoor air and can open to be connected to the communicating valve of inner tube lumen Yu perimetrical lumen 6 (thus being constituted complete Interior Space tracheae internal channel) in due course.Wherein, the axially outer end end face of purification air hose internal channel should be arranged in citation damper, and the interior shaft end for purifying air hose internal channel at this time is connected to air suction device 15, entered with providing power suction air.Meanwhile air intake in the interior shaft end communication chamber of the other of inner tube lumen and perimetrical lumen 6, communicating valve should be arranged between the axially outer end of inner tube lumen and the axially outer end of perimetrical lumen 6.

In the embodiment shown in figure 1, perimetrical lumen 6 has been selected to purify air hose internal channel.In the case, inner tube 1 is to be connected to the interior circulation air inlet pipe of indoor air inlet.Referring to fig. 2, outdoor air inlet A at this time flows into perimetrical lumen 6 from outside to inside, and indoor air inlet B enters from the interior shaft end of inner tube lumen, turns in perimetrical lumen 6 in the axially outer end of inner tube lumen, finally flows out from the interior shaft end of perimetrical lumen 6.
