Description
One, technical field
The utility model relates to gas cleaning plant, is a kind of dedusting, desulphurization plant that is used for boiler and industrial furnace flue gas.
Two, background technology
At present China is equiped with surplus the Industrial Boiler 40 ten thousand altogether, and a year consumption raw coal amount reaches more than 200,000,000 ton, adds other industrial furnaces, and quantity is quite surprising.These coal-fired furnace kilns are poor owing to coal adaptability, and the thermal efficiency is low, reasons such as incomplete combustion, and the flue dust of generation has seriously polluted atmospheric environment.The harmful components of industrial furnace smoke evacuation mainly are sulfur dioxide (SO
2) waiting gas and dust, the flue gas that has these pollutants lets alone to enter atmosphere as without purification, will threaten human existence.For this reason, administering with the coal is the boiler of fuel and the smoke contamination of industrial furnace, has become the task of top priority.For flue dust is separated from flue gas, various dedusters have appearred, and they all are to utilize different active forces, separate and the capture flue dust." Industrial Boiler stoker reader " the middle introduction of publishing in 1998 as China Electric Power Publishing House has: gravity settling chamber deduster, inertial dust separator, cyclone dust collectors and wet scrubber.The gravity settling chamber deduster generally can only capture the bulky grain flue dust, and efficient is lower, and the efficiency of dust collection of inertial dust separator is about 70%, cyclone dust collectors also claim centrifugal collector, efficiency of dust collection can reach 92%, be most effective a kind of in mechanical precipitator, but its shortcoming is can't desulfurization.Wet scrubber is a hydrophily of utilizing dust in the flue gas, washes flue gas with water, thus the device that smoke catching is got off." the centrifugal water dust scrubber " introduced in " Industrial Boiler stoker reader " is typical wet scrubber.It is reached by outer cylinder body, overflow tank or nozzle ring formula liquid distribution, ash bucket, ash discharge water sealing (sealing water) pipe forms into and out of fume pipe.Though this wet scrubber efficiency of dust collection can reach more than 90%, can only remove pernicious gas (as SO
2) about 15%, desulfurized effect is poor, and contains more water droplet in the flue gas after being purified, easily causes flue and air-introduced machine to produce accidents such as corrosion.
Three, summary of the invention
The purpose of this utility model is the shortcoming that exists at the wet scrubber prior art, and a kind of high-efficiency desulfurizing dust-collector is provided, and it has simple in structure, dedusting, desulfuration efficiency height, advantage such as the flue gas after being purified dehydrating effect is good.
The utility model is achieved through the following technical solutions its purpose.A kind of high-efficiency desulfurizing dust-collector, it comprise general deduster vertical cylindrical shell, be positioned at smoke inlet pipe, the ash bucket of cylindrical shell bottom, be positioned at the dewater unit and the exhanst gas outlet on cylindrical shell top, and the inlet that is positioned at the cylindrical shell middle and upper part.It is characterized in that: vertical cylindrical shell is divided into and gives purifying area, purifying area, drying zone three parts, and the barrel diameter of middle part purifying area is less.The smoke inlet pipe is " ∧ " shape (crotch shape), enters the purifying area cylindrical shell along horizontal two inlets, is communicated with the purifying area cylindrical shell after giving purifying area cylindrical shell undergauge.Below the purifying area cylindrical shell, be provided with swirl-flow devices, above the purifying area cylindrical shell, be provided with inlet.Be communicated with the drying zone cylindrical shell after the top hole enlargement of purifying area cylindrical shell, establish double-deck dewater unit in the drying zone cylindrical shell.Establish the spirality guide vane in the swirl-flow devices.Double-deck dewater unit is at the periphery of the circular shelves water plate that is positioned at the cylindrical shell middle part, and opposite lower clapboard in inclination angle and upper spacer longitudinally are set, and is connected with barrel with annular plate washer between the two-layer up and down dividing plate, uses cover closure on the top of upper spacer.Circular shelves water plate is by middle mind-set periphery, horizontal by 15 degree angles.Annular plate washer upper edge barrel is provided with leaking hole.
The utility model is because the smoke inlet pipe is " ∧ " shape, and two-way incision cylindrical shell makes two strands of dust-contained airflows form strong head-on collision, not only grit is thrown to barrel and is sink to ash bucket by centrifugal force greatly because of density, simultaneously, flue gas mixes with the akaline liquid that purifying area flows down above, make flue gas cool-down on the one hand, reach the effect of flue gas preliminary purification.Owing to be communicated with the purifying area cylindrical shell after giving purifying area cylindrical shell undergauge, purifying area is provided with swirl-flow devices, therefore, flue gas through preliminary purification, by obtaining acceleration behind undergauge and the swirl-flow devices, form the sharply ascending air of rotation, with the akaline liquid cutting that flows down along barrel, be broken into uneven drop, flue gas is thrown toward wall with drop and forms moisture film under action of centrifugal force, flue gas is fully mixed with drop, and the granule in the flue gas constantly adheres to, cohesion, form bulky grain, the liquid down that continued to flow by inwall pours the following purifying area that gives and clashes and be admitted to ash bucket.Simultaneously, alkali lye is with the SO in the flue gas
2Gas further washs absorption, makes the SO in the flue gas
2Concentration is lower than national specified discharge standard.Therefore, the utlity model has dedusting, advantage that desulfuration efficiency is high.Because the cylindrical shell hole enlargement between purifying area and the drying zone, flue gas enters the drying zone flow velocity and slows down, and because the middle part is provided with circular shelves water plate, shelves water plate periphery is provided with the opposite two-layer longitudinal baffle up and down in inclination angle, the upper spacer cover closure, therefore, flue gas can only be around rising between the lower clapboard on it, continuous and dividing plate, a shelves water plate clash into, and the moisture content in the flue gas is removed effectively., under the guiding of air-introduced machine, do not send into smoke stack emission from the exhanst gas outlet at cylindrical shell top with the flue gas up to standard of moisture content.Therefore, the utility model also has the good advantage of tail gas dehydrating effect.In addition, the utility model compared with similar products, under dedusting, glue sulphur efficiency same case, simple in structure, small investment has good economic benefit.
