Abstract
The utility model relates to a cyclone dust collector, including flue gas inlet pipe, gas discharge tube, heating jacket and water back, the heating jacket sets up at the cyclone dust collector surface, be provided with the water back between heating jacket and the cyclone dust collector, the water back entrance point is connected with the flue gas inlet pipe, and the water back exit end is connected with the flue gas inlet pipe and lies in water back entrance point and flue gas inlet pipe and links to each other after the contact. The utility model overcomes the problem of dew point corrosion has enlarged the occasion that cyclone dust collector used.
Description
Technical field
This utility model relates to a kind of cyclone dust extractor, particularly relates to a kind of high-temperature flue gas be carried out dust removal process
The cyclone dust extractor at place.
Background technology
Cyclone dust removal, as a kind of outstanding dedusting method, is approved by masses, the applied field of cyclone dust extractor
Close and also get more and more, but needing to process the occasion of some high-temperature flue gas possessing certain humidity, cyclone dust removal
The surface contacted with high-temperature flue gas in device is susceptible to dewpoint corrosion problem, greatly limit cyclone dust extractor
Application.So-called dewpoint corrosion refers to, owing to element sulphur generates SO2, SO3 when burning, work as heat-transfer surface
Hull-skin temperature less than flue gas dew point temperature time, heat-transfer surface will be formed sulfuric acid mist dewdrop, cause heat exchange
Face is corroded.
Utility model content
The purpose of this utility model be for the deficiencies in the prior art in place of, the problem overcoming dew point corrosion, expand
The occasion that big cyclone dust extractor uses.
A kind of cyclone dust extractor, including smoke feed pipe, gas outlet pipe, heating mantle with add hot channel, described
Heating mantle is arranged on cyclone dust extractor outer surface, is provided with and adds heat pipe between described heating mantle and cyclone dust extractor
Road, described heating pipe head is connected with smoke feed pipe, heating pipe outlet and smoke feed pipe phase
Connecting and being positioned at heating pipe head is connected after contact with smoke feed pipe.
As preferably, described gas outlet pipe is cylindrical shape, and described gas outlet pipe is arranged on cyclone dust extractor top
End.
As preferably, described gas outlet pipe entrance point is positioned under the smoke feed pipe port of export.
As preferably, described smoke feed pipe is cylindrical shape, and described smoke feed pipe diameter is discharged with described gas
The diameter ratio of pipe is: 9:10.
The beneficial effects of the utility model:
(1) this utility model utilizes the heat of high-temperature flue gas self to heat cyclone dust extractor so that rotation
In wind cleaner unit, the surface temperature with high-temperature flue gas contact surface is higher than flue gas dew point temperature, it is to avoid leak source corrosion phenomenon
Generation.
(2) this utility model is by preventing what dew point corrosion was taked its heat of heating measures from high-temperature flue gas
Itself, energy-conserving and environment-protective.
Accompanying drawing explanation
For clearer explanation the technical solution of the utility model, in embodiment being described below required for make
Accompanying drawing be briefly described, it should be apparent that, drawings discussed below is only more of the present utility model
Embodiment, from the point of view of those of ordinary skill in the art, on the premise of not paying creative work, also may be used
To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is cyclone dust extractor overall structure schematic diagram.
Label declaration:
1. smoke feed pipe, 2. gas outlet pipe, 3. heating mantle, 4. add hot channel.
Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is clearly and completely illustrated.
Embodiment
Fig. 1 is cyclone dust extractor overall structure schematic diagram.As it is shown in figure 1, the present embodiment provides one
Cyclone dust extractor, including smoke feed pipe 1, gas outlet pipe 2, heating mantle 3 with add hot channel 4, described
Heating mantle 3 is arranged on cyclone dust extractor outer surface, is provided with heating between described heating mantle 3 and cyclone dust extractor
Pipeline 4, described in add hot channel 4 entrance point and be connected with smoke feed pipe 1, add hot channel 4 port of export and cigarette
Gas feed pipe 1 is connected and is positioned at and adds hot channel 4 entrance point and be connected with smoke feed pipe 1 after contact；Described
Gas outlet pipe 2 is cylindrical shape, and described gas outlet pipe 2 is arranged on cyclone dust extractor top；Described gas is arranged
Go out pipe 2 entrance point to be positioned under the smoke feed pipe port of export；Described smoke feed pipe 1 is cylindrical shape, described cigarette
Gas feed pipe 1 diameter with the diameter ratio of described gas outlet pipe 2 is: 9:10.
Work process of the present utility model: the high-temperature flue gas containing certain moisture first enters heating from smoke feed pipe
Pipeline, starts to heat cyclone dust extractor from cyclone dust extractor top, prevents dew point corrosion, then, add
Flue gas in hot channel returns smoke feed pipe from cyclone dust extractor lower end.Hereafter, flue gas enters from smoke feed pipe
Enter cyclone dust extractor, after dust removal process, discharge cyclone dust extractor through gas outlet pipe；Cyclone dust extractor bottom
Being provided with passage, be provided with valve in passage, the dust granules in cyclone dust extractor can be low from cyclone dust extractor
End discharges cyclone dust extractor.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model
It is not limited thereto, the technical scope that any those familiar with the art discloses at this utility model
In, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore,
Protection domain of the present utility model should be as the criterion with the protection domain of claims.
