Abstract
The utility model discloses a flue-gas-driven centrifugal water film scrubber used for flue gas purification and emission of a coal-fired industrial boiler. The flue-gas-driven centrifugal water film scrubber comprises a water storage sedimentation tank, a water inlet, a sewage outlet, an overflow port, a flue gas inlet, a flue gas outlet and an induced draft fan, and is characterized in that a first mixing chamber and a second mixing chamber which are closed are arranged on the water storage sedimentation tank, a rotary blade wheel is arranged in the first mixing chamber, blades of the rotary blade wheel are spoon-shaped, spherical grooves with smaller capacities and water-dividing comb teeth are uniformly formed between the spoon-shaped grooves and the ends of the blades of the rotary blade wheel, and the sinking directions of the spherical grooves are opposite to those of the spoon-shaped grooves. The flue-gas-driven centrifugal water film scrubber takes flue gas as power to impact the rotary blade wheel, so that droplets splash to collide with the first mixing chamber to form a water film, accordingly, electric energy and water resources are remarkably saved, and the running cost is low; and flue gas is purified and dedusted twice and the dedusting performance is perfect.
Description
Technical field
The utility model belongs to the gas purification technique field, is specifically related to a kind of for the centrifugal water film dust removal device of coal-burned industrial boiler gas cleaning discharged flue gas power.
Background technology
The water film dust removal device widespread usage is installed between boiler economizer and the boiler induced-draft fan in the middle-size and small-size coal-burned industrial boiler of China, and its effect is to filter contained grit in the flue gas.Generally adopt wet type granite water film dust technology at present, this technology combines whirlwind with moisture film, efficiency of dust collection is 95%, have significant dust removing effects, but that its shortcoming is equipment volume is tall and big, numb stone main cylinder height is at least more than 3 meters, the construction cost height, and need uninterruptedly supply water and keep enough pressure, power consumption and water consumption are bigger than normal, the operating cost height.
Summary of the invention
For addressing the above problem, the utility model provides a kind of smoke power centrifugal water film dust removal device.The utility model can obviously reduce construction cost, operating cost, energy-saving and water-saving in the intensified dust removal performance.
The utility model for achieving the above object, the technical scheme of employing is as follows:
The centrifugal water film dust removal device of a kind of smoke power, comprise retaining sedimentation basin, water inlet, sewage draining exit, overfall, gas approach, exhanst gas outlet, air-introduced machine, it is characterized in that: the first high-order partition wall, the second high-order partition wall are arranged, the bottom of the first high-order partition wall, the second high-order partition wall and the intercommunication of retaining sedimentation basin on the retaining sedimentation basin; There is the first airtight mixing chamber the uncovered top that the first high-order partition wall and retaining sedimentation basin edge form, and there is the second airtight mixing chamber the uncovered top that the second high-order partition wall and the first high-order partition wall form; Gas approach is positioned on the sidewall of first mixing chamber, the rotating vane wheel is arranged in first mixing chamber, be communicated with by bend pipe between first mixing chamber and second mixing chamber, there is the arc deflection plate bend pipe port in second mixing chamber, and air-introduced machine is communicated with second mixing chamber by exhanst gas outlet.
The blade of aforementioned rotating vane wheel is a spoonful shape, is evenly equipped with the less spherical groove of volume and divides the water broach between the blade termination of spoon connected in star and rotating vane wheel.
The depression direction of aforementioned spherical groove is opposite with the depression direction of spoon connected in star.
The blade plane line of aforementioned minute water broach and rotating vane wheel is 45 ° of angles.
The lowest part of aforementioned rotating vane wheel is positioned at the following 1cm-3cm of the water surface.
Adopt technique scheme, the mobile flue gas that forms when working with air-introduced machine is power, the high speed flue gas that spoon connected in star on the rotating vane wheel of the present utility model is subjected to gas approach promotes, the rotation at a high speed of driven rotary blade wheel, the spherical groove contact water surface of the blade termination of rotating vane wheel is also taken the bolus of water out of, be centrifugal tangential direction after being divided the water broach to cut apart and fly out, collision forms bounce-back in first mixing chamber's inner wall surface and is broken down into littler water smoke; The constantly rotation of rotating vane wheel, more boluses of water are centrifugal to fly out and collision reaction thereby make, and forms sealing moisture film chamber in first mixing chamber; Owing to exporting at a high speed, flue gas sends caused venturi underbalance effect forth around adding gas approach, flue gas in first mixing chamber and the mixture part of water smoke are back to around the smoke inlet, be rotated the stirring of blade wheel and mixed flow collision again, can make the fusion that fully contacts, circulates with water smoke of the grit of flue gas, most of granularity is deposited to the cistern bottom greater than the grit of 0.3 μ m being thrown into the water surface; Granularity is continuously taken second mixing chamber less than the grit of the 0.3 μ m bend pipe by first mixing chamber to flue gas, because the arc deflection plate of second mixing chamber has stopped that flue gas moves upward, the grit that flue gas carries less than 0.3 μ m is folded to side's operation on the lower side, the flue gas layer that formation jumps on the water surface causes grit in the flue gas by secondary separation and sedimentation, so that reaches the purpose of smoke abatement and dust control.
The utility model is dynamic impact rotating vane wheel with the flue gas, the globule is splashed collide first mixing chamber formation moisture film, has significantly saved electric energy and water resource, and operating cost is cheap; Flue gas is carried out purifying and dedusting twice, further strengthened dust removal performance; The blade of rotating vane wheel can pass through the mould punch forming, and the integral constructing cost is less.
