Embodiment
Below in conjunction with the accompanying drawings and instantiation the present invention is described in detail.
Referring to Fig. 1, the laboratory smoke gas disposal evaluation study platform of the embodiment of the present invention, including coal-burning boiler 1, powder blower
7th, bag filter 4, the automatic on-line detecting system 10 for testing 4 efficiency of dust collection of bag filter, can to carry out dust equal
Even heating diffusion container 6, cooler 3 and the control system 5 being controlled to powder blower 7 for being distributed and heating；Control system 5 can
The pressure of dusting of powder blower 7 is adjusted, is used, fired when the flue gas that powder blower 7 can be produced in coal-burning boiler is insufficient
Coal burning boiler 1 is sequentially connected cooler 3 and bag filter 4 by flue gas exhausting pipe line, on the flue gas exhausting pipe line of coal-burning boiler 1
The dust detector a2 of detection dust content is provided with, bag filter 4 is connected by pipeline with heating diffusion container 6, cloth bag
Dust detector b13 is provided with the pipeline that deduster 4 is connected with heating diffusion container 6, appearance is provided with heating diffusion container 6
Receive dust cavity and in being provided with resistive heater in cavity, heating diffusion container 6 passes through the cigarette that pipeline accesses coal-burning boiler 1
Gas discharge tube, the pipeline that flue gas exhausting pipe line is connected with heating diffusion both containers 6 is linked into after dust detector a2
Flue gas exhausting pipe line on, heating diffusion container 6 at the same time be connected with can to itself conveying dust powder blower 7, powder blower 7 with control
System 5 processed is connected and is controlled by control system 5, and powder blower 7 is connected with the first control wind turbine 8；Bag filter 4 and heating
Spread and the second control wind turbine 9 is provided with the pipeline that container 6 connects, a branch is connected on the pipeline after the second control wind turbine 9
Pipeline, the flue gas emission valve 11 and the 3rd that control flue gas emission is provided with the lateral control wind turbine 12.
The laboratory smoke gas disposal evaluation study platform of the embodiment of the present invention when in use, if coal-burning boiler produce flue gas
When insufficient, the first control wind turbine 8 can be opened, powder blower 7 is controlled by control system 5, and then the spray of powder blower 7 can be changed
Powder pressure, the dust for thus making to add in powder blower 7 are entered in heating diffusion container 6 by a hose, and dust passes through
Resistive heater in heating diffusion container 6 is heated so that and the flue-gas temperature that dust comes out with coal-burning boiler is consistent,
Due to being provided with the first control wind turbine 8, dust enters in the cavity of heating diffusion container, by the first control wind turbine 8
Effect can form strong turbulent flow, and the pencil dust sprayed from hose will be evenly distributed on inside heating diffusion container, passed through
The effect of second control wind turbine 9, dust enter bag-type dust together with the flue gas that coal-burning boiler is discharged by flue gas exhausting pipe line
Device 4 carries out dedusting, and dust content, evaluation bag filter dedusting effect are detected by dust detector a2 and dust detector b13
Rate.
When being tested, can according to requirement of experiment, allow powder blower spray Monosized powder material, such as 20 μm, 30 μm,
The dust of the different Monosized powders such as 50 μm respectively enters heating diffusion container, and the temperature of heating is the same and is uniformly distributed, and carries out
The research of same granularity dust efficiency of dust collection simultaneously contrasts varigrained efficiency of dust collection by field experiment, or allows powder blower to spray
Go out the mixture of a variety of granularities, for example, 20 μm, 30 μm, 50 μm, 70 μm, the varigrained dust such as 90 μm be combined doping,
The temperature similarly heated is the same and is uniformly distributed, by the efficiency of dust collection of a variety of grain sized mixtures of field experiment comparative evaluation,
Powder blower can also be allowed to spray dust etc. of different material combination grain, for example, sulfide, nitrogen oxides, fluoride, calcium oxide,
The dust materials such as silica are combined doping, similarly control heating-up temperature the same and are uniformly distributed, pass through field experiment
The efficiency of dust collection of comparative evaluation's different material mixing, is finally reached the dedusting effect of experimental study different grain size dust and compounding substances
Rate.When being tested, when burning boiler produce flue-gas temperature do not reach also requirement of experiment or flue gas diffusion it is not equal enough
Even, flue gas enters heating diffusion container from pipeline, and internal resistive heater can heat flue gas, by flue gas
To different temperatures, influence of the dust to bag filter efficiency of dust collection from low temperature to high temperature is studied.
The foregoing is merely the example of the present invention, it is not intended to limit the invention, it is all in the spiritual and former of the present invention
All any modification, equivalent and improvement made within then etc., should all be included in the protection scope of the present invention.
