Description
Technical field
The present invention relates to a kind of water wet method and remove the device of acid ingredient in the Industrial Boiler flue gas, injection well downhole flow regulator and demister Combination Design in particularly a kind of absorption tower.
Background technology
At present, in modern industry is produced, a large amount of fire coal or oil burning boilers of using provide power, especially the power station boiler large amounts of fuel that need burn, yet these use the boiler of fossil fuel inevitably to discharge a large amount of flue gases, enter in the flue gas because the sulphur component that contains in the fuel generates sulfur dioxide in burning, do not enter in the atmosphere if flue gas does not add to handle, with causing serious atmosphere pollution and acid rain, nature and human habitat are damaged.In the prior art, before boiler smoke enters atmosphere, all to carry out purified treatment, discharge again after removing acidic components such as sulfur dioxide wherein.The method that boiler smoke is carried out purified treatment has a variety of, and wherein using the absorption tower that flue gas is carried out that wet cleaning handles is a kind of method of generally using.Use the absorption tower to be to the process that flue gas carries out the wet cleaning processing, be equipped with from top to bottom successively on the absorption tower: demister, injection well downhole flow regulator and packing layer, undressed flue gas is imported the absorption tower from the bottom, and the filler on flow through orifice plate and the orifice plate is discharged from the outlet of top, absorption tower; The shower nozzle of the injection well downhole flow regulator on top, absorption tower is shower water downwards, and through countercurrent spray, the acidic components in the flue gas are soluble in water to be deviate from from flue gas, and waste water is discharged from bottom, absorption tower delivery port; Filler in the absorption tower increases the contact area of flue gas and water, and demister is set to remove vaporific moisture in the flue gas of discharging above injection well downhole flow regulator.
Existing absorption tower is in tower inside beam to be set, support the demister of injection well downhole flow regulator and its top respectively, wherein injection well downhole flow regulator has a person in charge, be responsible for an end from this water inlet is set, vertical UNICOM is in being responsible for both sides respectively for a plurality of arms, and a plurality of shower nozzles are arranged in each arm below, and water is pumped into injection well downhole flow regulator, flowing through to be responsible for enters each arm, and a plurality of shower nozzles spray to filler the absorption tower from the top on each arm.The design of this structure since injection well downhole flow regulator and demister be supported on respectively on the brace summer and boss on the main-body structure of absorption tower, there is a segment distance between the two, make equipment more open on the whole, not only raised the height on absorption tower, and raised other flue gas purifying equipments that are associated with the absorption tower, increased equipment construction input and operating cost; The person in charge of injection well downhole flow regulator and arm all are to intake from an end, in service at physical device, the person in charge and arm exist bigger pressure to fall from the water inlet end to the far-end, the shower nozzle that causes diverse location on the arm is because hydraulic pressure difference ejection water smoke shape difference, the water spray space occurs, can not realize all standing, make untreated flue gas to spill by these spaces to the absorption tower internal cross section, reduce the degree of purification of flue gas, cause exhaust emission.
The innovation and creation content
In order to solve the technological deficiency that prior art exists, the object of the present invention is to provide a kind of annular water distribution and demister composite set, can make each arm shower nozzle stable water pressure balance of injection well downhole flow regulator, and make injection well downhole flow regulator, the demister section construction on absorption tower compact practical.
To achieve these goals, the technical scheme of the invention is:
A kind of annular water distribution and demister composite set comprise injection well downhole flow regulator and demister, wherein:
-injection well downhole flow regulator has the person in charge, arm, branched pipe, water inlet and shower nozzle, be responsible for ringwise, be responsible for opposite side and respectively have a water inlet, a plurality of arms are distinguished UNICOM in being responsible for both sides, wherein be in the arm two ends of ring main central authorities and corresponding person in charge UNICOM, branched pipe between arm, the adjacent arm of branched pipe two ends UNICOM; Arm and branched pipe towards below place a plurality of shower nozzles are set evenly, the water smoke of its ejection can all cover the absorption tower internal cross section;
-reinforcement is connected with the arm upper fixed;
-inverted T-shaped fixed mount places the reinforcement top;
-demister places on the inverted T-shaped fixed mount.
The inverted T-shaped fixed mount can be made of back-to-back two groups of dihedral section bars.
Because after adopting such scheme, the present invention in use, demister places on the reinforcement of injection well downhole flow regulator arm by the inverted T-shaped fixed mount, rather than by the supporting of the structural beams on absorption tower, make the absorption tower reduce brace summer and space thereof, make equipment compact more, other the flue gas purifying equipment height relevant with the absorption tower of also corresponding reduction have simultaneously significantly reduced construction cost and operating cost.Because injection well downhole flow regulator is responsible for ringwise, and opposite side respectively has a water inlet, make be responsible in each the position differential water pressures is different reduces, a plurality of arms are distinguished UNICOM in being responsible for both sides, wherein be in the arm two ends of ring main central authorities and corresponding person in charge UNICOM, branched pipe is between arm, the adjacent arm of branched pipe two ends UNICOM makes from being responsible for shower nozzle and supplies water from both direction, and the water supply distance is short, pressure stability in the pipe, pressure reduction is little, makes the shape of shower nozzle atomized water spray identical, and the water smoke of its ejection can all cover the absorption tower internal cross section, improve shower nozzle water spray level of coverage to the flue gas that passes through in the absorption tower, optimized the gas cleaning effect.
