Fig. 1 is the structural representation of a kind of hot and humid flue gas bag-type dusting deashing device.
Fig. 2 is the structural representation of air preheater in Fig. 1.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings, it is simple to more clearly
Understand this utility model, but they do not constitute restriction to this utility model.
As it is shown in figure 1, a kind of hot and humid flue gas bag-type dusting deashing device, including flue gas master
Pipe 1 and sack cleaner 2, flue gas is responsible for 1 front end and is connected with air preheater 3；In conjunction with Fig. 2
Shown in, air preheater 3 is pipe heat exchanger, and it includes casing 3-1, casing 3-1 front end
Having gas approach 3-2, rear end has exhanst gas outlet 3-3, and bottom has preheated air import
3-4, top has preheated air outlet 3-5, is sequentially provided with front hole in casing 3-1 from front to back
Plate 3-6, heat-exchanging tube bundle 3-8 and rear orifice plate 3-7, this heat-exchanging tube bundle 3-8 is Steel Thin-Wall tube bank,
The front end of heat-exchanging tube bundle 3-8 be fixed on the front orifice plate 3-6 of steel and with gas approach 3-2 phase
Logical, the rear end of heat-exchanging tube bundle 3-8 be fixed on the rear orifice plate 3-7 of steel and with exhanst gas outlet 3-3
Communicating, the pipeline enclosure of heat-exchanging tube bundle 3-8 leaves air and crosses gas gap 3-9；Air preheater 3
Gas approach 3-2 and flue gas supervisor 1 between be connected with flue gas air intake branch 6, air preheater 3
Exhanst gas outlet 3-3 and flue gas supervisor 1 between be connected with flue gas and go out gas branch pipe 7, air preheater 3
Hot air outlet 3-5 each cloth pocket with sack cleaner 2 respectively connect, these are even
It is respectively provided with hot air control valve 4, and the hot air outlet end of air preheater 3 on leading in succession
It is provided with preheated air blower fan 10；Flue gas be responsible for 1 end respectively with each cloth of sack cleaner 2
Pocket connects, and these connect and are respectively provided with flue gas control valve 11 on pipeline, described
Flue gas control valve 11 is the most contrary with the open and-shut mode of described hot air control valve 4；Pocket type removes
The purifying smoke port of export of dirt device 2 is connected with smoke discharging pipe 8, and smoke discharging pipe 8 is provided with air-introduced machine
9, smoke discharging pipe 8 end is connected with chimney 12；Ash-clearing structure 5 it is connected with on sack cleaner 2,
This ash-clearing structure 5 is pulse jetting deashing mechanism, and pulse jetting deashing mechanism includes compressed air
