Working principle:
Upper tube cell road 4, powder cabin 1, roof scrubber 2, deduster inlet ductwork 3, house outlet pipeline 5, absorber 11
And net gas exhaust outlet 9 is sequentially connected one complete gas passage of composition on absorber, absorber upper space passes through net gas
Exhaust outlet 9 and atmospheric environment connection.
Gas and powder enter powder cabin 1 by upper tube cell road 4 simultaneously, and most of powder is influenced directly to drop to by gravity
In powder cabin 1, small part powder is suspended in space in powder cabin 1, and powder feeding gas constantly accumulates in powder cabin 1, makes in powder cabin 1 pressure not
It is disconnected to rise, to guarantee that pressure is in safe range in powder cabin 1, and guarantee that upper powder process can continue, needs gas in powder cabin 1
Body discharge, the gas of suspension a large amount of dust carry out primary dedusting into roof scrubber 2 by deduster inlet ductwork 3 first,
Self-operated type gas distribution regulating mechanism 6 is provided on deduster inlet pipeline 3, self-operated type gas distributes regulating mechanism 6 according to storehouse
The gas of interior pressure automatic running, suspension a large amount of dust is entered by the entrance in deduster inlet ductwork 3, due to two groups of baffles
The thickness of 6-2 is different, and the threshold value with respective cracking pressure is different, when pressure is higher than the cracking pressure threshold value of certain baffle in storehouse
When, this corresponding baffle 6-2 is opened, and it is automatic to enable the corresponding roof scrubber 2 of baffle, it is collected by roof scrubber 2
Dust by being entered in dust leg 7-1 with 2 dust-exhausting port of roof scrubber, dust leg 7-1 is for dust collection and temporarily depositing
Storage；When Dust Capacity is less in dust leg 7-1, the dust-exhausting port tight closure of self-locking end plate 7-3 and dust leg 7-1 prevent air-flow
Disorder guarantees deduster dust removing effects, when dust runs up to constant weight in dust leg 7-1, the lower end of self-locking end plate 7-2 by
Pressure is fallen to be separated with the dust-exhausting port of dust leg 7-1, and dust drops in powder cabin 1, and after dust landing, self-locking end plate 7-2 is pressurized
Power is released, and is reset to and dust leg 7-1 dust-exhausting port tight closure state；The movement guide rod 7-3 and guide rod spacing collar 7-
4, it falls in self-locking end plate 7-2 in reseting procedure, limits the direction of motion of self-locking end plate 7-2, guarantee that its resets reliability.
Dusty gas carries out first order dedusting by roof scrubber 2, and the dust of trapping passes through 2 lower part of roof scrubber
Self-locking gas dust discharge mechanism 7 is discharged, and falls into powder cabin 1, and the micro- dust-contained airflow of roof scrubber 2 except dust and gas export pipeline 5 by entering
11 carry out depth recycling in absorber, and remaining micro dust absorbed liquid absorption is above to constitute complete dedusting process, whole powder
Dirt is all effectively collected, and realizes the nearly zero leakage of dust.
Roof scrubber 2 is at least 2 groups, and the group number upper limit is chosen according to powder feeding equipment gas flow, up to 8 groups, multiple groups
Roof scrubber can be arranged symmetrically, other suitable arrangements can also be used using powder cabin axis as center circumference uniform distribution.
1 dust removing units can be only set inside same group of deduster, 2~3 unit dedusters also can be set and share
One group of deduster inlet ductwork 3 and self-operated type gas distribute adjustment structure 6, when one group of deduster contains multiple unit dedusters
When, need to be arranged partition 12 between each adjacent two unit deduster, when one group of deduster contains only a unit deduster,
Setting partition is not needed then.
Each unit deduster requires one self-locking gas dust discharge mechanism 7 of configuration.
Centrifugal dust collector can be used in roof scrubber 2, and inertial dust separator can also be used, both have it is durable,
Feature at low cost, operating cost is low, centrifugal dust collector are suitable for the thinner dust of particle, and inertial dust separator is suitable for particle
Thicker dust.
Sealing surface between sealing edge strip 6-1 and baffle 6-2 can be simple L-type, be also possible to waveform or saw
Tooth form is selected and needs to be determined according to specific deduster inlet ductwork size, and lesser caliber is suitble to apply L-type sealing surface, compared with
Big caliber is suitble on the sealing surface for using waveform or zigzag sealing surface, sealing edge strip 6-1, can inlay a circle rubber
Airtight and watertight padding.
In wet desulfurization system, desulfurization slurry preparation, which fills, is used as absorber 11, in powder cabin before powder, first adds into pulping tank
Water uses water as absorbing liquid to the gas distribution of net 10-2 above 50cm in lower surface, using slurrying, absorbing liquid absorb after dust directly into
Process system normal use is become owner of, desulfurizing agent needed for the desulfurizer powder absorbed can offset a part of slurrying.
The water that is humidified in dry method perhaps semi-dry desulphurization system fills or adjusting material preparation fills and is used as absorber 11, powder cabin
Before upper powder, the gas distribution of net 10-2 above 50cm in lower surface is first added water into tank, with water or the adjusting material dissolution water work of being humidified
For absorbing liquid, absorbing liquid is directly entered main process system normal use after absorbing dust, and the desulfurizer powder absorbed facilitates
Promote desulfuration efficiency.
In oxidizing process denitrating system, oxidant dissolution, which fills, is used as absorber 11, in powder cabin before powder, first adds water into tank
The gas distribution of net 10-2 above 50cm in lower surface, using oxidant dissolution water be used as absorbing liquid, absorbing liquid absorption dust after directly into
Process system normal use is become owner of, solid oxidation needed for the oxidant powder absorbed can offset a part configuration solution
Agent.
The utility model is applied when in fine coal ash cellar, and boiler dust remover is as absorber 11 described in the utility model, storehouse
It pushes up the exhaust of deduster 2 and enters boiler dust remover, do not discharged to atmosphere.
