Description
Technical field
The application relates to a kind of spiral moisture film compound dust-collection device.
Background technology
At present, domestic and international existing dedusting method mainly includes following four mode:
The first, electricity-bag dedusting method, which adopts electrostatic absorption principle to carry out dedusting, can trap the dust of less than 1 μm; it is usable in the occasions such as High Temperature High Pressure, has certain use to limit to, invest higher; Resistance Influence by dust is relatively big, and maintenance difficulty, maintenance must be shut down；
The second, cloth-sack-type dust removal, cloth bag in cleaner unit is the outstanding problem in cleaner unit running, the dust that humidity is bigger should there be is segregation apparatus, for the impact to cloth bag of other dust, it is the main cause causing cloth bag to damage, so the cloth bag waste of sack cleaner is relatively big, leverages efficiency of dust collection；
The third, cyclone type dedusting, which produces centrifugal force by dusty gas, is separated by dust from air-flow, has certain limitation for the dust efficiency of more than 5-10 μm is higher, and volume is bigger；
4th all ways are wet dust removals, and dust is soluble in water, and efficiency of dust collection is high, and application is wide, and some environment especially for bargh are comparatively severe, and the place of the unfavorable factors such as dust humidity is big carries out dust removing effects and becomes apparent from.But its water consumption is relatively big, and cost of sewage disposal is higher, and easily causes secondary pollution.Such as: existing aerosolater all utilizes water to spray for medium, needs continuous make-up water source in During Process of Long-term Operation, water resource waste is relatively big and in spray process, water quality requirement is also relatively strict, high-pressure fog it is frequently necessary to soften in advance.
The correlation technique content of the application has no report.

Detailed description of the invention: the application, not by the restriction of following embodiment, can determine specific embodiment according to the technical scheme of the application and practical situation.
Embodiment: as shown in Figure 1, spiral moisture film compound dust-collection device includes gas-liquid dirt pocket 5, it is communicated with spray chamber 8 in gas-liquid dirt pocket 5 upper end, it is communicated with liquid collecting room 22 in gas-liquid dirt pocket 5 bottom, liquid collecting room is connected with bulky grain Sedimentation tank 20 by scum pipe 21 for 22 times, and connected with the water inlet end in sedimentation filtration pond 17 by discharging tube 23, water side, sedimentation filtration pond 17 is provided with liquid feeding pump 15, gas-liquid dirt pocket 5 bottom is provided with air inlet pipe 2, the rotating shaft 25 of setting it is provided with in gas-liquid dirt pocket 5, the thread mixing blade 7 on screw it is placed with on rotating shaft surface, gas flow passage is formed between thread mixing blade 7 and gas-liquid dirt pocket 5, it is filled with dedusting liquid in this passage and gas-liquid dirt pocket 5, it is provided with shower 11 in spray chamber 8 above thread mixing blade 7, shower 11 is connected with liquid feeding pump 15 by feed tube 13.
As it is shown on figure 3, described thread mixing blade 7 horizontal cross-section is a disc, this disc diameter is equal to gas-liquid dirt pocket 5 internal diameter.Air inlet 24 is left in thread mixing blade 7 bottom, topmost leaves gas outlet 26.
The air vent 9 of gas after spray chamber 8 upper end is provided with to discharge dedusting, inside air vent 9, be provided with to remove in gas steam except mist net 10, it is prevented that steam secondary pollution.
At spray chamber 8, gas-liquid dirt pocket 5 intersection being provided with overflow pipe 12, overflow pipe 12 connects with the water inlet end in sedimentation filtration pond 17.
Because dust-contained airflow to overcome the hydrostatic head of fluid just can enter in gas-liquid dirt pocket 5, therefore being provided with to increase the booster fan 3 of admission pressure at air inlet pipe 2 place, can adopt high-power vortex fan (2KW) conduct is power.For preventing dedusting liquid stream in gas-liquid dirt pocket 5 from going out, air inlet pipe 2 and gas-liquid dirt pocket 5 connectivity part are provided with air inlet non-return valve 4 and air inlet electromagnetic valve.
Some roads filter screen 16 it is arranged at intervals with between the water inlet end and water side in sedimentation filtration pond 17.
As shown in Figure 1, 2, feed tube 13 is provided with feed liquor flow-limiting valve 14, discharging tube 23 is provided with draining solenoid valve 18, scum pipe 21 is provided with deslagging electromagnetic valve 19, in spray chamber 8, be provided with dust sensor.Described dust sensor, feed liquor flow-limiting valve 14, draining solenoid valve 18, deslagging electromagnetic valve 19, liquid feeding pump 15 are connected with Non-follow control cabinet or PLC circuit, and booster fan 3 is connected with PLC circuit by a converter.Control program it is preset with in PLC.Thus realizing manually and automatically controlling dedusting.
When dedusting, dust source 1 is entered gas-liquid dirt pocket 5 by air inlet pipe 2 with the form of some bubbles, bubble is entered by thread mixing blade 7 air inlet, bubble, in uphill process, can only move along the helical channel between thread mixing blade 7, and bubble is after every layer of blade bottom of thread mixing blade 7 is crushed, it is fully contacted with dedusting liquid, owing to the surface tension effects of liquid makes dust be wet, so that dust and bubble separation, to realize dedusting purpose.Bubble after being crushed considerably increases the time contacted in gas-liquid dirt pocket 5 with dedusting liquid in the process that spiral flows up, thus realizing the purpose of high efficiency dedusting.
Dedusting liquid is for recycling, dust constantly precipitates to liquid collecting room 22 after being dissolved in dedusting liquid or suspends, after bulky grain sedimentation, Direct precipitation is to bulky grain Sedimentation tank 20, can not directly settle, by discharging tube 23, the dedusting liquid after dedusting be drained in sedimentation filtration pond 17, by obtaining the dedusting liquid of cleaning after dosing, filtration treatment, dedusting liquid is by, in the shower 11 in liquid feeding pump 15 pressurized delivered to spray chamber 8, carrying out final dusting to the air-flow after purifying.For preventing spray flux excessive, install overflow pipe 12 in spray chamber 8 dedusting ullage specific bit and be drained in sedimentation filtration pond 17.
In automatic dust removing process, booster fan 3 is equipped with converter, PLC intake is adjusted., according to dust sensor, the dust concentration in spray chamber is detected meanwhile, PLC control the liquid inlet volume of feed liquor flow-limiting valve 14, whether the break-make of control draining solenoid valve 18, whether the break-make of control deslagging electromagnetic valve 19, controls liquid feeding pump 15 and whether works, thus realizing the purpose of automatic dust removing.
Obviously, the described above of the application is only for clearly demonstrating the application example, and is not the restriction to presently filed embodiment.Apparent change that every technical scheme belonging to the application is amplified out or variation are still in the row of the protection domain of the application.
