Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The dust pelletizing system of flue gas produced by a kind of sludge high temperature processing disclosed in the present embodiment, referring to shown in Fig. 1 and Fig. 2,
Activated carbon and sodium acid carbonate are transported to injector 11 by activated carbon and sodium acid carbonate by LS types metering screw conveyer, pass through spray
Emitter 11 has been ejected into venturi reactor 7, with the cigarette exported from chilling extracting tower 23 being passed through in venturi reactor 7
Gas is vigorously mixed, and air vapor heater 15 is connected with the pipeline of venturi reactor connection gas approach, from a point vapour
The vapours that cylinder 26 is passed through is heated air by air vapor heater 15, and the air of heating is together passed into flue gas enters
Mouthful, maintain after activated carbon and sodium acid carbonate and flue gas mixing, the temperature of mixed gas does not decline.Mixed flue gas is passed through position afterwards
In the gas approach of middle casing 2, by the work of poppet 10 in the casing locellus 17 in upper box make flue gas by filter bag 4 come
To upper box 1, the dust in flue gas is attached to the outer surface of filter bag 4.As the outer surface adhesive dust of filter bag 4 gradually increases, air-flow
Also gradually increased by resistance, the impulse electromagnetic valve 9 being located in filter pocket openings is opened as needed, compressed air is from injection tube 8
Middle penetrating filter bag 4, makes filter bag 4 once expand, shakes off the dust that the adhering on surface of filter bag 4.Compressed air is will by air compressor machine
Outside air compression is provided, and in the air accumulator for being stored in sack cleaner 20, injection tube 8 is connected with air accumulator by pipeline
Connect, while impulse electromagnetic valve 9 is installed in the duct to control whether to spray compressed gas, when gas ejecting system 19 needs work,
Impulse electromagnetic valve is opened, and compressed air sprays from injection tube.Dust, which leaves, falls into underlying ash bucket 3 behind the surface of filter bag 4, lead to
The cinder-discharging port 14 for opening the lower section of ash bucket 3 is crossed, the dust of deposition sack cleaner 20 is cleaned out into, dust is transported by grey car 24.
Flue gas leads to SCR catalytic reactors 27 by exhanst gas outlet after filtering.
In flue gas mixed active charcoal, using dry active powdered carbon, because dry active powdered carbon has great specific surface area,
The heavy metal such as bioxin, mercury in flue gas can be adsorbed, making these original can not be removed because particle is excessively small by filter bag 4
Pollutant, as dry active powdered carbon is filtered by filter bag 4 together.Spraying sodium bicarbonate solid can be anti-with sour gas in flue gas
Should, improve the quality of flue gas.Both injected volume can be controlled by metering screw conveyer 16, it is therefore prevented that the cloth to after
Bag dust collector 20 causes excessive pressure.Dry active powdered carbon and sodium bicarbonate solid are when being attached to 4 outer surface of filter bag simultaneously, energy
Continue the flue gas being filtered through, improve dedirt rate.
Mixed flue gas is passed through the gas approach 11 positioned at middle casing 2, and gas approach 11 is provided with spark arrester 21, spark arrester 21
It is fixedly connected with the frame of gas approach 11, and bottom is provided with opening.Stopped the flow direction for changing mixed gas by spark arrester 21,
The Mars that is carried in air-flow will not be caused to filter bag 4 as the stop of spark arrester 21, falls in underlying ash bucket 3
Infringement.
The hot blast stove air blast 12 set in ash bucket is removed the dust being attached on the wall of ash bucket 3 by being passed through hot blast.Pass through
Electric heater unit 13 in hot blast stove air blast 12 and cinder-discharging port is together operated, it is therefore prevented that when cinder-discharging port 14 unloads ash, in ash bucket 3
Because temperature changes dew condensation phenomenon damage equipment occurs for portion.
Shown in Figure 3, upper box is made up of four casing locellus 17, according to different flue gas situations, by controlling not
With the poppet in casing locellus 17, to control dedusting speed.The outer surface of filter bag 4 in a casing locellus is adhered to too many
After dust, stop the work of the poppet 10 of casing locellus 17.By the injection tube 8 above filter pocket openings, open as needed
Impulse electromagnetic valve 9, compressed air sprays into filter bag 4 from injection tube 8, filter bag 4 is once expanded, and shakes off the adhering on surface of filter bag 4 and
Dust.Dust, which leaves, falls into underlying ash bucket 3 behind the surface of filter bag 4.Then proceed to open the progress dedusting work of poppet 10
Make, other casing locellus 17 are unaffected at the same time, operating alone.
In whole dust removal process, flue gas mixes dry active powdered carbon and sodium bicarbonate solid in venturi reactor 7, with
It is passed through middle casing 2 together afterwards, is changed the Mars being full of behind flue gas direction in whole middle casing 2, flue gas by spark arrester 21 and also hindered
Firearm is stopped.By the work of poppet 10 in each casing locellus in upper box 1, the mixed flue gas for being in middle casing 2 is carried
Be raised in upper box 1, again during flue gas have passed through the filtering of filter bag 4, dust, dry active powdered carbon and sodium bicarbonate solid are all
It is isolated in the outer surface of filter bag 4.By injection system 19, the solid of the outer surface of filter bag 4 attachment is shaken off into ash bucket 3, then
The dust removal flue gas discharged in sack cleaner 20, upper box 1 is passed through SCR catalytic reactors 27 by exhanst gas outlet 10.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
