As shown in Figure 1, the present invention includes secondary rotary air duct 1 and one cyclonic cylinder 2, described secondary rotary air duct 1 is arranged at one cyclonic cylinder 2 inside and coaxially arranges with one cyclonic cylinder 2, closing up gradually and form drier outlet 10 in the bottom of described one cyclonic cylinder 2, closes up gradually and form wet feed outlet 11 in the bottom of described secondary rotary air duct 1; The upper end sidepiece of described one cyclonic cylinder 2 arranges blast pipe 13, arranges spiral stream guidance blade 3 between the inwall of described one cyclonic cylinder 2 and the outer wall of secondary rotary air duct 1, and the top of described secondary rotary air duct 1 arranges water film dedusting case 4, middle part arranges air inlet 12.
The inside of described blast pipe 13 arranges dry fog pipe 9, the axis perpendicular of described dry fog pipe 9 and blast pipe 13 and uniform dry fog injection hole on it.
Arrange overflow plate 8 in described water film dedusting case 4, described overflow plate 8 is cone-shaped structure, and its cone angle scope is 90 ~ 130 °; The top of described overflow plate 8 arranges water inlet pipe 5, and the outer wall connection water source of water film dedusting case 4 is run through in one end of described water inlet pipe 5, and the other end of described water inlet pipe 5 arranges shower nozzle 6, and described shower nozzle 6 is positioned at directly over the cone angle of overflow plate 8.
The top of described water film dedusting case 4 is provided with demister 7.
The one in silica gel, montmorillonite, molecular sieve or fluffy felt is loaded in described demister 7.
As shown in Figure 2, to run through the bottom outer wall of one cyclonic cylinder 2 extended in described wet feed outlet 11.
The dust collecting process of the two centrifugal dust collection device of dry fog moisture film, described processing step is as follows:
Suppressing dust with dry mist: dust-laden exhaust gas is entered by blast pipe 13, under the effect of dry fog that the dry fog injection hole that dry fog pipe 9 is arranged evenly sprays, the dust granules in dusty gas and dry fog are united combination, and dust size is increased;
One cyclonic dedusting: the dust granules after particle diameter increases carries out screw settling along the spiral stream guidance blade 3 between the inwall and the outer wall of secondary rotary air duct 1 of one cyclonic cylinder 2, and the dust granules after one cyclonic dedusting is discharged by drier outlet 10;
Secondary cyclone dust removal and water film dedusting: the gas after one cyclonic dedusting enters secondary rotary air duct 1 by air inlet 12; The water that shower nozzle 6 sprays flows down along the gap formed between overflow plate 8 and the inwall of secondary rotary air duct 1, the gas entered by air inlet 12 area of giving vent to anger in this gap diminishes, gas flow rate increases, impact the current flowed down from overflow plate 8 from bottom to top, form moisture film, the powder slurry formed after dust in moisture film and gas combines is dirty along the inwall of secondary rotary air duct 1, exports 11 discharge by wet feed;
Demist: the gas after water film dedusting is discharged in air after demister 7 demist.
operation principle of the present invention and the course of work as follows:
The present invention combines with a centrifugal dust-removing by adopting dry fog dedusting, then in conjunction with the technical process of water film dedusting and secondary centrifuging dedusting, substantially increases efficiency of dust collection, enhance dust removing effects; Use this dust arrester, PM100 treatment effeciency >=99%, PM10 treatment effeciency >=95%, PM2.5 treatment effeciency >=85%, effectively can process particle diameter and be less than 10 μm and oiliness, stickiness, high humidity, band Mars or inflammable and explosive property dust-laden exhaust gas, the socket join structure that this device uses has saved floor space, is more suitable for applying.
During work, dust-laden exhaust gas enters from the blast pipe 13 of one cyclonic cylinder 2, the dry fog pipe 9 that blast pipe 13 inside is arranged forms dry fog air curtain, dust-laden exhaust gas is after dry fog air curtain, dust granules is combined the dust forming larger particle with dry fog, enter again in the screw settling space that formed between one cyclonic cylinder 2 and secondary rotary air duct 1 and carry out primary separation, discharge from drier outlet 10 after the oarse-grained dust formed being transported to mouth by centrifugal force by spiral stream guidance blade 3, completing the gas after primary separation enters in secondary rotary air duct 1 from the air inlet 12 of secondary rotary air duct 1, the water that shower nozzle 6 sprays flows down along the gap formed between overflow plate 8 and the inwall of secondary rotary air duct 1, gas area of giving vent to anger in this gap diminishes, then gas flow rate increases, current from bottom to top under impingement flow, form moisture film, moisture film can remove the dust granules that size is 5 μm ~ 10 μm, now dust and moisture film combine, in conjunction with after powder slurry by wet feed export 11 discharge, demister 7 is made up of the dry matter do not reacted with dedusting gas or drier, as silica gel, montmorillonite, molecular sieve or fluffy felt etc., clean gas after process is by being discharged in air after demister 7 demist.
The floor space of dry-wet one dust-laden exhaust gas treating apparatus is saved when wet feed outlet 11 is coaxially arranged with drier outlet 10; When the bottom outer wall that wet feed outlet 11 runs through one cyclonic cylinder 2 is extended, realizes the collection respectively of dry wet dust, be independent of each other.
