Description

Water film type gravitational dust collection devulcanizer

Technical field

The utility model relates to a kind of desulfation dust-extraction device, relates in particular to a kind of water film type gravitational dust collection devulcanizer.

Background technology

Common wet method sulphur removing and dust removing cleaning equipment has atomizing, cyclone type, water storage flush water bath type, column plate type, venturi etc.But usually owing to sulfur-bearing in the flue gas, contact rear so that cleaner corrodes easily with water.Secondly owing to be subjected to the restriction of various factors, the efficiency of dust collection of single deduster is not very high, and in order to improve desulfurization dust-removing efficiency, if simply the high duster parallels of difference, often equipment volume is too huge, be unfavorable for actual production, and it is large to coordinate difficulty in the equipment clean, Operation and Maintenance also bothers very much.

Summary of the invention

The purpose of this utility model is to provide a kind of water film type gravitational dust collection devulcanizer, and it has simple in structure, the advantage of efficiency of dust collection height and convenient operating maintenance.

The utility model is achieved like this, it comprises air inlet, left expansion chamber, grenadine, the gas outlet, valve, ash bucket, right expansion chamber, middle setting chamber and housing, the left side and the right side that it is characterized in that housing are respectively equipped with air inlet and gas outlet, left expansion chamber is positioned at the housing under the air inlet, right expansion chamber is positioned at the housing under the gas outlet, also be provided with middle setting chamber in the housing between left expansion chamber and the right expansion chamber, left expansion chamber, middle setting chamber and right expansion chamber all are connected by valve with the ash bucket that is positioned at housing bottom, be provided with grenadine in the housing between left expansion chamber and the middle setting chamber, be provided with grenadine in the housing between middle setting chamber and the right expansion chamber, the housing that is positioned at directly over the left expansion chamber also is provided with grenadine.

Technique effect of the present utility model is: the utility model has improved the purification efficiency of coal-fired flue-gas, so long as through catharsis repeatedly, so that efficient is improved, effectively reach the purpose of desulfurization and dedusting, have simple in structurely, use operation also very convenient and purify lower-cost advantage.

Description of drawings

Fig. 1 is structural representation of the present utility model.

In the drawings, 1, air inlet 2, left expansion chamber 3, grenadine 4, gas outlet 5, valve 6, ash bucket 7, right expansion chamber 8, middle setting chamber 9, housing.

The specific embodiment

As shown in Figure 1, the utility model is achieved like this, it comprises air inlet 1, left expansion chamber 2, grenadine 3, gas outlet 4, valve 5, ash bucket 6, right expansion chamber 7, middle setting chamber 8 and housing 9, its design feature is that left side and the right side of housing 9 is respectively equipped with air inlet 1 and gas outlet 4, left expansion chamber 2 is positioned at the housing 9 under the air inlet 1, right expansion chamber 7 is positioned at the housing 9 under the gas outlet 4, also be provided with middle setting chamber 8 in the housing 9 between left expansion chamber 2 and the right expansion chamber 7, left expansion chamber 2, middle setting chamber 8 and right expansion chamber 7 all are connected by valve 5 with the ash bucket 6 that is positioned at housing 9 bottoms, be provided with grenadine 3 in the housing 9 between left expansion chamber 2 and the middle setting chamber 8, also be provided with grenadine 3 in the housing 9 between middle setting chamber 8 and the right expansion chamber 7, the housing 9 that is positioned at directly over the left expansion chamber 2 also is provided with grenadine 3.

The utility model purification process is such, when the sulfur-bearing dust enters in the deduster by air inlet 1, at first under the gravity of oneself, part dust settling get off (purify for the first time), grit during through the grenadine 3 between left expansion chamber 2 and the middle setting chamber 8, makes gas wetting in left expansion chamber 2 depositions, allow the inter coagulation of particle phase, at self gravitation or flow into the 8(of middle setting chamber by the moisture film on the grenadine 3 and purify for the second time); Then gas enters the grenadine 3 between middle setting chamber 8 and the right expansion chamber 7, when same gas passes through moisture film, make the particle of not sedimentation further wetting, cohesion, increase the weight of self gravitation, thereby middle setting chamber's 8 sedimentations (purifying for the third time), in whole desulfurization decanting zone, by wetting dust repeatedly and with grenadine 3 multiple impacts after, make dust be easier to be hunted down, moisture film is under the self gravitation effect, dust stays into settling tank, and the pond inner surface forms moisture film equally, thereby effectively reduced reentrainment of dust dedusting is affected, gas outlet 4 above right expansion chamber 7 also arranges one deck grenadine 3, the dust that allows the front not capture condenses again, and dust enters again right expansion chamber 7(and purifies for the 4th time in the effect of self gravitation), assembled at ash bucket 6 by valve 5 by the dust granules of sedimentation at last, the utility model Effective Raise boiler dusting desulfuration efficiency, deduster all adopts grouan material, has reduced equipment investment cost.
