Description
Technical field
The present invention relates to a kind of desulfurizer, especially desulfurizing tower annular water-distributing device.
Background technology
The water-distributing device of existing desulfurizing tower typically uses the water distribution form of main pipeline and fishbone type in tower, in fishbone type
Shower nozzle is arranged on branch pipe, on the tower body of desulfurizing tower, the lower disposed manhole of every layer of spraying layer, is used with doing maintenance.When containing SO2's
High-temperature flue gas are sufficiently mixed into desulfurizing tower with atomization doctor solution, because under the using of high-temperature flue gas, partial desulfurization liquid is in spray
Head surface is concentrated by evaporation, local to produce supersaturation to separate out, and sticks to nozzle surface, causes shower nozzle or line clogging, serious shadow
Desulfurizing tower desulfurized effect is rung, boiler is eventually caused and is forced shutdown maintenance, directly affect the normal production schedule.
The content of the invention
To solve the above problems, the present invention provides a kind of normal operation for not influenceing desulfurizing tower, overhauls convenient desulfurizing tower
Annular water-distributing device, concrete technical scheme is：
Desulfurizing tower annular water-distributing device, including annular water distributor, spray branch pipe and shower nozzle, the annular water distributor are fixed on desulfurization
Tower outside, described spray branch pipe one end is located at desulfurizing tower inner side, and the other end is located at desulfurizing tower outside, sprays the mounting flange of branch pipe
On the tower flange of desulfurizing tower, the other end for spraying branch pipe is equipped with adpting flange, the adpting flange and annular water distributor
Water pipe flange connection, the shower nozzle be arranged on spray branch pipe on, and positioned at desulfurizing tower inner side.
Preferably, the spray branch pipe is provided with multiple, and is distributed on inside desulfurizing tower.
Preferably, the spray branch pipe includes spray branch pipe and short spray branch pipe long, the shower nozzle on the spray branch pipe long
No less than two, the shower nozzle on the short spray branch pipe is no less than one.
Spray branch pipe is become activity installation by mounting flange and adpting flange, dimension can be pulled down from desulfurizing tower
Repair.
The connecting tube of desulfurizing tower and the aperture of tower flange are larger, make the spray branch pipe for being provided with shower nozzle convenient to remove.
During desulfurization, doctor solution enters annular water distributor from the water-in flange of annular water distributor, subsequently into spray branch pipe, from
The shower nozzle for spraying branch pipe sprays.
During maintenance, the fixing bolt on mounting flange and adpting flange is pulled down respectively, by spray branch pipe from inside desulfurizing tower
Release, cleaning shower nozzle is carried out outside desulfurizing tower or shower nozzle is changed, it is not necessary to shutdown maintenance, it is ensured that the safe operation of boiler
Cycle, while having ensured that being normally carried out for sequence is held in production.
On the applicable 20T/H double alkali method desulfurizing devices of the present invention, invest small, it is easy to operate, desulfuration efficiency is improve, solve
Because shower nozzle is blocked and caused by blowing out, stop production, ensured that production is held sequence and is normally carried out.
By experiment, dedusting, desulphurization and denitration system in the heat conducting oil boiler of 12,000,000 MW, every 40 work originally
It is accomplished by shutdown maintenance, cleaning shower nozzle day once.After using annular water-distributing device, every 30 working days are once checked, clearly
Reason shower nozzle work, continuously runs 90 working days, and the safety and economic operation of boiler is not influenceed because of the failure of desulphurization plant
And the normal operation of production.The equal qualified discharge of indices.
Compared with prior art the invention has the advantages that：
The desulfurizing tower annular water-distributing device for providing of the invention is simple and reliable for structure, do not need shutdown maintenance, outside desulfurizing tower i.e.
Can be changed, be cleared up shower nozzle, it is ensured that the desulfuration efficiency of desulfurizing tower and the safe operation cycle of boiler, while having ensured that production is held
Sequence is normally carried out.
