Description
Technical field
It the utility model is related to desulfurizer field, more particularly to a kind of desulfurization spray absorber.
Background technology
It is well known that problem of environmental pollution has received the extensive concern of various circles of society, solve problem of environmental pollution and exist
Arrived in a way and do not allowed slow stage.
Wherein, for China urban, air pollution is the most important thing in problem of environmental pollution, and it is former to study carefully it
Cause, on the one hand it is due to that the discharge capacity of vehicle exhaust increases year by year, is on the other hand due to the waste gas emission problem of heavy industry.
In fact, most enterprises give enough attention in waste emission problem, but due to China
Its Technical Development History is shorter in terms of preventing and treating environmental pollution compared with western developed country, equipment also more fall behind, these because
Element is that the economic development of the high speed with China at this stage is incompatible.
Specifically, it is the core apparatus of flue gas desulfurization on China desulfurization industry absorption tower, is to carry out desulphurization reaction, completes

Liquid film collect, the concave surface end through drip ring 5 is broken into drop again when flowing down, and is assigned in flue gas.
The spraying layer includes the shower 8 stretched into inside tower body, and shower 8 stretches out one end and the desulfurization slurry of tower body 1
Transfer pipeline (not shown) connects, and one end that shower 8 is stretched into tower body 1 is evenly distributed with several nozzles 9.Taken off by jet flow layer
The gas of sulphur slurries spray process flows up along in tower body 1, and desulfurization slurry is by transfer pipeline through several on shower 8
Nozzle 9 is sprayed, and the pending gas for ensureing to flow through in tower body 1 can be sprayed, and ensures spray quality.
It is a close to the distance between the edge of the nozzle 9 of the inwall of tower body 1 and the inwall of tower body 1, the nozzle 9 is horizontal
Injection displacement is b, and for horizontal-jet displacement b no more than nozzle 9 and the inwall distance a of tower body 1, horizontal-jet displacement b is the outside of nozzle 9
Horizontal range of the edge to the horizontal-jet farthest of nozzle 9.The slurries of adherent flowing can be reduced, can be mitigated again to the inwall of tower body 1
Anticorrosive coat washes away, you can the slurries of adherent flowing is brought extra power into play, overcomes wall flow phenomenon and cause the negative of desulfuration efficiency reduction
Face rings.
The shower 8 is fixed by fixed seat 10 and tower body 1, one end that shower 8 is stretched into inside tower body 1 and tower body 1
Inwall is vertical.Plane where shower 8 is vertical with the inwall of tower body 1, ensure that and flows through pending gas in tower body 1 by most
Large-scale spraying effect.
Preferably, the quantity of the spraying layer is three layers, and the lower section of shower 8 of every layer of spraying layer is all fixed with drip ring
5.Drip ring 5 is all set below every layer of spraying layer, the wall flow liquid for making pending gas will often to collect by a spraying layer
Film 7 is broken into drop again, is assigned in flue gas, ensures by every layer of spraying layer because central area distribution slurries are more, resistance
More spray times are needed greatly, are optimal spray process effect.
The demisting layer includes two layers and rinses layer 4 and demister 6, and two layers of flushing layer 4 is fixed on the top of demister 6
On the inwall of tower body 1 of lower section；It is upper and lower two layers flushing layer 4, ensure by demister 6 processing after dust will not because of accumulation shadow
Ring the treatment effect of demister 6.The demister 6 is fixed on the annular ledge 11 on the inwall of tower body 1, it is described flushing layer 4 with
The inwall of tower body 1 is perpendicularly suspended in the fixing lug boss 13 on the inwall of tower body 1.Rinse the plane and demister 6 at the place of layer 4
The plane at place is all vertical with the inwall of tower body 1, ensure that the pending gas flowed through in demister 6 is all processed, ensures to remove
Fog effect.
Preferably, the quantity of the demisting layer is two layers, it is described above and below rinse layer 4 to the direction of demister 6
Spray process water.
During specific works, pending gas enters by gas approach 2 from the bottom of tower body 1, successively by three layers of spray
After layer and two layers of demisting layer processing, flowed out via the exhanst gas outlet 3 on the top of tower body 1；When flowing through each layer of spraying layer, by shower
8 sprays form wall flow liquid film 7, when flowing through drip ring 5, drip ring 5 to the desulfurization slurry on the inwall of tower body 1 along the inwall of tower body 1
Wall flow liquid film 7 on the inwall of tower body 1 collects, and is broken into drop again through drip ring 5, is assigned in flue gas；Flue gas adverse current
During flowing up, because central area distribution slurries are more, resistance is big, and needs by more desulfurization slurry spray times,
Spraying layer, bulk devulcanization efficiency high could be departed from；Side wall area distribution slurries are few, and resistance is small, and desulfuration efficiency is low, form side wall
Escape, drip ring 5 can force flue gas to be flowed in dash ring segment from the inner wall area of tower body 1 to central area, effectively stop cigarette
Gas is escaped along tower body inwall, improves the desulfuration efficiency on absorption tower；When flowing through demisting layer, processing gas is needed by vertical tower body 1
The demister 6 of wall is excluded after flowing out by exhanst gas outlet 3, meanwhile, the flushing layer 4 of upper and lower both direction is to the spray processing of demister 6
Water, to prevent from, because of the dust accumulated plugging in demister 6, influenceing defogging effect；Rinsing layer 4 by flush pipe and can be uniformly distributed
Several technique (operating) water nozzles in flush pipe are formed, and equally distributed several technique (operating) water nozzles can guarantee that to the clear of demister entirety
It is clean.
The utility model is additionally arranged drip ring 5, can be effectively improved slurries wall flow phenomenon, while can reduce flue gas side wall
Escape risk, so as to improve the desulfuration efficiency on absorption tower, while the nozzle 9 that can also will be close to tower body inwall can also be arranged
From the inwall of tower body 1 far, i.e., the distance between the edge of the nozzle 9 of the close inwall of tower body 1 and the inwall of tower body 1 are a, described
The horizontal-jet displacement of nozzle 9 is b, and horizontal-jet displacement b can reduce sticking wall flow no more than the nozzle 9 and inwall distance a of tower body 1
Dynamic slurries, it can mitigate again and tower body inner wall anti-corrosive layer is washed away, you can the slurries of adherent flowing is brought extra power into play, overcome wall
Flow phenomenon causes the negative effect that desulfuration efficiency reduces.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims protection domain.
