Description
Technical field
The utility model relates to environmental protection dedusting, flue gases purification field, especially a kind of flue-gas dust removal and purification system.
Background technology
Along with developing rapidly of modern industry, the demand cumulative year after year of electric power, the electric power of China more than 70% comes from the coal-burning power plant, and is when generated energy increases, more and more serious to the pollution of environment.Main component nitrogen oxide, oxysulfide, carbon dioxide etc. in the coal-burning boiler flue dust; Also contain more a spot of hydrogen, methane gas and other hydrocarbons in addition.The chemical composition of flying dust is mainly silica, aluminium oxide, and the two total amount is generally more than 60%.Also contain the combustible in the flying dusts such as a spot of iron oxide, sodium oxide molybdena, potassium oxide, calcium oxide, magnesia, titanium oxide, phosphorus pentoxide, sulfur trioxide in addition.
These stain thing environment and health have been brought very big harmful effect, therefore must carry out udst separation to waste gas and handle.Along with society is more and more higher to the degree of concern of atmosphere pollution, strong day by day to the attention of air contaminant treatment, the standard that exhaust emission is handled is also more and more higher.
At present, the subject matter that exists in the coal-fired plant flue gas cleaning system: dust pelletizing system operating cost height in the day-to-day operation; The dust pelletizing system running resistance, particularly the filtration resistance of later stage filter bag is higher; The cloth bag breakage rate is higher, and the filter bag whole service life is shorter; The improper global failure risk of filter bag is high.
The utility model content
The utility model is at the deficiencies in the prior art, and a kind of efficiency of dust collection height, equipment cost is low, operation energy consumption is low flue gas purification system are provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flue-gas dust removal and purification system comprises boiler, dust removing units, and desulfurization unit, spray washes the unit, conveyance conduit, bag-type dusting unit, defeated grey unit, deashing unit, conveying fan, chimney and bypass channel; Wherein said boiler connects dust removing units successively, desulfurization unit, conveyance conduit, bag-type dusting unit, conveying fan, chimney; Described spray washes the unit and connects desulfurization unit, and described bag-type dusting unit connects deashing unit and defeated grey unit respectively, and described bypass channel connects conveyance conduit and conveying fan respectively.
Described dust removing units is cyclone dust collectors.
On bag-type dusting unit and the bypass channel valve is set.
The bag-type dusting unit is sack cleaner.
The method that the flue-gas dust removal and purification system is used comprises the steps:
(1) gas of boiler discharge carries out dust removal process;
(2) handle through desulfurization through the gas after the dedusting, spray simultaneously and wash;
(3) gas enters sack cleaner through transfer passage outside cloth bag, carries out dust-filtering, through pulse jet dust is dropped, and the dust that sack cleaner is collected transfers out through defeated grey unit;
(4) enter flue collector through the clean flue gas behind the cloth bag filtration through exhanst gas outlet, by the air-introduced machine traction, discharge by chimney.
The technical scheme that the utility model provides at the defective of existing flue gas purification system, provides a kind of efficiency of dust collection height, equipment cost is low, operation energy consumption is low flue gas purification system and method.
Description of drawings
Fig. 1 is the process chart of the utility model flue-gas dust removal and purification system
1-boiler, 2-cyclone dust collectors, 3-desulphurization system, 4-spray system, 5-conveyance conduit, 6-bypass channel valve, 7-sack cleaner, 8-ash-transmission system, 9-soot cleaning system, 10-conveying fan, 11-chimney
The specific embodiment
The utility model, the technical scheme among the embodiment is clearly and completely described below in conjunction with the accompanying drawing in the present embodiment for better illustrating.
The specific embodiment as shown in Figure 1, the dusty gas that boiler 1 is discharged enters into cyclone dust collectors 2 inside by the flue collector of stove tail, flue gas is got rid of through cyclone dust collectors 2 and is entered desulphurization system 3 behind the bigger grit and carry out desulfurization, spray system 4 can spray flue gas simultaneously, promotes desulphurization reaction and reduces flue-gas temperature; Open the valve of each deduster front and back, the flue gas after handling through desulfurization enters into sack cleaner 7 through conveyance conduit 5 and carries out dedusting, and flue gas enters cloth bag from the cloth bag outside, and dust is filtered on the cloth bag surface, and 9 winding-ups of process soot cleaning system are dropped dust; The dust that sack cleaner 7 is collected flows into the storage ash bucket through the unloading valve of deduster bottom, through ash-transmission system 8 outputs.Enter air-purifying chamber and blower fan 10 preceding flue collectors through the clean flue gas behind the cloth bag filtration,, be discharged in the atmosphere through smokejack and chimneys 11 by blower fan 10 tractions, at this moment, by-pass flue valve 6 is closed.
During boiler oil spout ignition trigger, open by-pass flue valve 6, make the oil-containing flue gas enter flue collector before the blower fan, the valve of closing each deduster unit by bypass channel; Boiler induced-draft fan is bled by flue collector and is drained into smokejack, by the chimney high altitude discharge.
Common dust pelletizing system is compared with dust separation system of the present invention, and the item argument contrast is as follows:
Use system of the present invention, the dust pelletizing system running resistance is steady, and resistance raises slowly after the long-time running.The required deashing pressure of novel glass varicosity overlay film cloth bag is low, and cleaning cycle is long, saves compressed air more than 50%, and the system maintenance amount reduces 30%.The flue-gas dust removal and purification system front end is provided with desulfurizer and realizes the efficient sulfur dioxide of removing, and desulfuration efficiency can reach more than 98%; Novel glass varicosity overlay film cloth bag have high-strength flatness, high temperature resistant, corrosion-resistant, refuse the anti-wet goods excellent specific property of water;, high humility big for Dust Capacity, moment, operating mode adaptive faculty such as high temperature was strong; be provided with bypass protector simultaneously and successfully manage accident; adopt novel glass varicosity overlay film cloth bag; dust is trapped within the cloth bag surface; realize surface filtration, have high arresting efficiency for PM10 and PM2.5 dust.While flue-gas dust removal and purification of the present invention system floor space is little, technological process is succinctly efficient, realizes low input, high production.Cross cloth precision height, dust emission is up to standard;
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the 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.
