Abstract
This invention relates to a granitic accelerated impact deduster and its making method. It includes air inlet connecting tube, two S-shape centrifugal purifying chambers with symmetrical section, dust collecting water seal chamber, and water make-up balancing dipper and sewage discharge valve connecting with dust collecting water seal chamber, air-liquid separating chamber fitted with multiple water baffles, air collecting chamber, air outlet connecting tube, base, and accelerated impact chamber with inverted trumpet-shape section. Its most members are made of natural granite adhered together with daub. It has advantages of effective rate of dedusting over 97%, removing rate of SO2 higher than 50%, no secondary pollution, small volume, large treating quantity, convenient operation, little water consumption, corrosion-proof, wear-resistant and long service life.
Description
The cleaner that the present invention relates to a kind of ash-laden gas is accelerated impact dust remover of granite and preparation method thereof.
In the 331st page of in August, 1984 China Construction Industry Press " industrial ventilation dedusting technology " Roto-clone type self-induced scrubber and in November, 1985 Shanghai science tech publishing house the Chemical Equipment Design pandect in disintegrating scrubber CCJ/A type dedusting unit in " cleaner design " the 375th page, after its dust-contained airflow enters body, air velocity all is to reduce greatly to flow downward, separate oarse-grained grit in the hope of grit by the gravitational settling effect, its efficiency of dust collection is low, especially in the air-flow in, short grained grit is failed sedimentation separation and is increased the weight of the load of back dedusting.Simultaneously, air-flow is more steady flowing of this interval, can not intensify water body, and no water smoke produces, and can't play the effect that water smoke is caught dirt.And above-mentioned dirt deduster is steel or the manufacturing of common metal material, and it is big not to be suitable for corrosivity, and the big gas purification of wearing and tearing especially is not suitable for the purified treatment of boiler smoke.
Originally the objective of the invention is to provide a kind of accelerated impact dust remover of granite of good dedusting effect, and a kind of preparation method of corrosion-resistant, anti abrasive above-mentioned accelerated impact dust remover of granite is provided.
For reaching above-mentioned purpose, the present invention has adopted the part-structure in Roto-clone type self-induced scrubber and the CCJ/A type dedusting unit and has formed through transformation, it comprises air inlet tube, the cross section of two symmetries is the centrifugal clarification chamber of " S " type, liquid level is sealed the control of dust water tight compartment of bottom, centrifugal clarification chamber and is communicated with the moisturizing balance bucket of control of dust water tight compartment, blowoff valve, in also comprising, it establishes the gas-liquid separation chamber of multilayer water fender, collection chamber, outgoing gas connection tube, base is characterized in that: it also is provided with, and top is communicated with air inlet tube, the bottom is communicated with the thereunder symmetrical centrifugal clarification of setting chamber, under be control of dust water tight compartment liquid level, the cross section gradually closing is for being inverted flaring accelerated impact chamber.The bottom of accelerated impact chamber is the acceleration throat that the both sides rectangular or cross section, cross section are circular arc, and its degree of depth is the 100-300 millimeter.The preparation method of above-mentioned deduster is, removes air inlet tube, outgoing gas connection tube, and outside the blowoff valve, all members all adopt the natural granite processing and fabricating to form, and member connects with anticorrosion, wear-resisting epoxy glue earth rubber and is assembled into integral body.
The present invention compared with prior art has following advantage: by test shows, its efficiency of dust collection is greater than 97%, SO
2Clearance is higher than 50%, and does not produce secondary pollution, and it is little not to be equipped with volume, takes up an area of and lacks, and treating capacity is big, convenient operation and management, and water consumption is few, and is corrosion-resistant, wear-resistant, characteristics such as long service life.
Accompanying drawing is a structural representation of the present invention.
Below in conjunction with accompanying drawing invention is described in further detail: as shown in the figure, it is by air inlet tube (1), accelerated impact chamber (2), quicken throat (3), symmetry serpentine centrifugal clarification chamber (4), gas-liquid separation chamber (5), collection chamber (6), outgoing gas connection tube (7), control of dust water tight compartment (8), moisturizing balance bucket (9), blowoff valve (10), pedestal (11), multilayer water fender (12) is formed.
When the present invention uses, ash-laden gas at first enters accelerated impact chamber (2) by air inlet tube (1), and dust-contained airflow is in this district, because of the down washing of the minimizing gradually speed increase in the cross section of flowing through, when air-flow enters acceleration throat (3), then reach the impulse air velocity (10-20m/s) of design.Grit in the air-flow is in downward impulse process, because the continuing to increase of air velocity, its strength of dashing is down also inclined to increasing, makes it to pour effectively in the water body of control of dust water tight compartment (8) and is captured, and has improved the efficiency of dust collection of equipment.
Acceleration air-flow through throat (3), its grit pour in control of dust water tight compartment (8) water body under gravity and action of inertia, and the dirt of most of larger particles and flow separation intensify the water surface simultaneously, form the water smoke space of certain altitude and density.By the air-flow behind the first class purification with after the water droplet of atomizing contacts, divide two strands of mixed airflows that also flow to enter the serpentine centrifugal clarification chamber (4) of left and right symmetry respectively, porch at " S " passage, air velocity was once quickened again, and fully contact with highdensity water smoke, make that more tiny grit is wetting in the air-flow increases the weight of, under action of centrifugal force, grit after the weightening finish is got rid of to the body serpentine passage smooth wall of chamber, the cohesion back flows into water body with water, reach and remove tiny grit, the effect of purifying gas flow once more.
The air-flow that is flowed out by serpentine centrifugal clarification chamber (4) promptly enters gas-liquid separation chamber (5), because of the cross section sudden enlargement, air velocity is reduced suddenly greatly, water droplet in the air-flow is under the gravity effect and sedimentation breaks away from air-flow, air-flow after the dehydration moves upward, contact with multilayer water fender (12), the water droplet in the separation bubble is controlled at below 6% the air-flow moisture content and discharges by collection chamber (6), outgoing gas connection tube (7) more once again.
Keep certain water level in the control of dust water tight compartment (8), the height of water level is definite when the operation debugging, but need seal the bottom of centrifugal clarification chamber (4).Be deposited in the taper bucket after the grit that is captured by accelerated impact and " S " centrifugal clarification chamber (4) falls into control of dust water tight compartment (8) water body, be in operation and discharge in dust-precipitator by blowoff valve (10) aperiodically.
Moisturizing balance bucket (9) is folded water amount in the water yield of replenishing high-temperature flue gas and being evaporated and the dust discharge mud, and water seal circle is controlled in the scope of design in the retainer, with the effect of guaranteeing dedusting and sloughing SO2.
Above-mentioned member removes air inlet tube (1), and outgoing gas connection tube (7) outside the blowoff valve (10), all adopts the natural granite processing and fabricating to form, and member connects with anticorrosion, wear-resisting epoxy glue earth rubber and is assembled into integral body.
