Description
Technical field
The present invention relates to environmental protection and resource reutilization technical field, and in particular to a kind of device for recovering powder.
Background technology
In current domestic flue gas dust collecting system, the dust reclaimer typically used is all relatively simple, is removed more using pocket type
Dirt device.In sack cleaner filter bag using the filter cloth or nonwoven felt of weaving into utilizing the filtration pair of fabric
Dusty gas is filtered, and after dusty gas enters sack cleaner, particle is big, heavy dust, due to the work of gravity
With settling down, ash bucket is fallen into, for the gas containing relatively fine dust when passing through filtrate, dust makes gas obtain only by detention
Change.
But sack cleaner is when in use, it is necessary to timely deashing, in order to avoid influence efficiency of dust collection, when in gas dustiness compared with
, it is necessary to adjust cleaning cycle shorter when big, frequently carrying out deashing to filter bag can cause the life-span of the filter bag of sack cleaner to contract
It is short.
The content of the invention
It is an object of the invention to provide a kind of device for recovering powder, to extend cleaning cycle.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of device for recovering powder, including fume ducts, fume ducts one end are provided with sack cleaner, gone back in fume ducts
Provided with pre- dedusting mechanism, pre- dedusting mechanism includes several shutters being axially distributed along fume ducts, and shutter includes some
The perforated shutter of individual parallel arrangement, perforated shutter are obliquely installed, and several perforated shutters are along fume ducts radial distribution；It is adjacent
Rotating shaft is provided between shutter and high-pressure spraying head, rotating shaft radially extend along fume ducts, rotating shaft is rotatablely connected with fume ducts,
Rotating shaft has been fixedly and coaxially connected cam；Fume ducts are externally provided with drive mechanism, and the drive mechanism includes driver plate and sheave, described
Sheave is fixedly and coaxially connected with rotating shaft, and sheave is provided with radial slot, and the driver plate is provided with the round pin that can be slided in radial slot,
The spray switch for controlling high-pressure spraying head to be opened and closed is fixedly connected with fume ducts outer wall, round pin, which is fixedly connected with, to be opened
Spray the projection of switch.
The operation principle of this programme is：
The passage that fume ducts are moved as flue dust, pre- dedusting mechanism are used to remove a part of dust in advance, reduce and enter
Dust Capacity in sack cleaner.When flue dust moves in fume ducts, because dust granules and gas molecule vary in weight,
Inertia force is also different in motion, and when the air-flow with dust runs into the perforated shutter being obliquely installed, the direction of air-flow drastically changes
Become, by the way that and dust granules are due to the inertia force than gas around perforated shutter and from the gap between adjacent perforated shutter
It is much bigger, still moved by former direction, therefore a part of dust follows air-flow from the gap between adjacent perforated shutter by separately
It is a part of then bump against with perforated shutter, perforated shutter surface is stayed in, because perforated shutter is provided with hole, sub-fraction air-flow also can be from
By carrying dust granules also from the hole of perforated shutter by the way that dust granules are left on perforated shutter in the hole of perforated shutter
Hole in.As the dust adsorbed in the hole of perforated shutter gradually increases, the throughput that perforated shutter passes through also is gradually reduced.
In order to keep the throughput that perforated shutter passes through substantially constant, there is provided high-pressure spraying head and cam.Drive mechanism
Rotated for band moving cam intermittence, in drive mechanism, driver plate, which rotates, drives the round pin on driver plate to move in a circle, when round pin enters
When entering sheave, sheave is driven and rotated by round pin, and when round pin leaves sheave, sheave transfixion, reciprocal with this, sheave is done
When it is dynamic when the intermittent movement that stops, sheave is used to drive rotating shaft intermittent rotary, and rotating shaft is used for band moving cam intermittent rotary, when cam
When lug boss and the shutter of cam both sides bump against, cam hits the dust in the hole of perforated shutter.High-pressure spraying head
For spraying water under high pressure to perforated shutter, the dust in the hole of perforated shutter is washed away.Spray switch is used to control high pressure
Spray head is opened and closed, and when the round pin on driver plate moves in a circle, spray switch is touched with the projection that round pin is fixedly connected, spray is opened
Control high-pressure spraying head spray is closed, the dust in perforated shutter hole is washed away.Drive mechanism is arranged to driver plate and sheave
Structure, be in order to realize cam fast ram shutter, and cam it is static time it is longer than the time of rotation.
Following technique effect can be reached using this programme：
1st, one of pre- dedusting mechanism of increase so that reduced into the fuel gas and dust amount in sack cleaner, cleaning cycle prolongs
It is long, and then the life-span of the filter bag of sack cleaner extends；
2nd, beaten and be engaged by high-pressure water jet and cam, the dust adsorbed in perforated shutter hole can removed, kept
The throughput that perforated shutter passes through is substantially constant；
3rd, on the one hand dust can be beaten by the effect of beaing of cam, on the other hand, moreover it is possible to by the hole of perforated shutter
Water under high pressure beats, and avoids the hole of perforated shutter from being lived by water blocking, influences dust absorbing；
4th, when beaing, water under high pressure is also avoided that dust from flying, beneficial to dust settling.
Further, shutter quantity is two.Using two shutters, cam, cam rotation are set between two shutters
When, two shutters can be hit simultaneously.
Further, perforated shutter is made of aluminum alloy materials.Aluminum alloy materials are not easy corrosion, and high temperature resistant, Bu Huiyou
It is too high in dust temperature and deform even destroy.
Further, the perforated shutter incline direction in neighboring louver is opposite.When air-flow is by two shutters, air-flow side
To can occur drastically to change twice, the dust in air-flow can produce mutual shock, consume portion of energy, and more conducively dust is heavy
Drop.
Further, flue dust drying device is provided between sack cleaner and pre- dedusting mechanism.By the gas of high-pressure spraying head
Steam is entrained with stream, the flue dust with steam, which is directly entered in sack cleaner, easily causes condensation trouble, and flue dust dries dress
Put for removing the steam in flue dust.
Further, cooling body is additionally provided with fume ducts, cooling body is located at pre- dedusting mechanism away from sack cleaner
Side, cooling body includes being affixed on water cooling tube on fume ducts outer wall.Cooling body can reduce the temperature of flue dust, and use water
Cooling, obtained hot water can also carry out subsequent recovery utilization.
