Description
Technical field
This utility model belongs to fume gas condensation liquid draining diversion technology field in Limestone-gypsum Wet Flue Gas Desulfurization Process chimney, tool
Body is a kind of chimney of preventing and treating gypsum rain.
Background technology
At present, most of desulfurization system for thermal power plant adopts Limestone-gypsum Wet Flue Gas Desulfurization Process technique, eliminates gas-gas
Heat exchanger（Gas gasheater, GGH）Neat stress is directly discharged by device from chimney, and chimney adopts inside lining anti-corrosive material, shape
Become the scheme that " Wet chimney " discharges.After the desulphurization system of no GGH device is gone into operation, though efficiently avoid the blockage problem of GGH,
Because the moisture content in flue gas after wet process of FGD raises, flue-gas temperature drops to 55 DEG C about simultaneously, moisture content in flue gas
Up to 11% ~ 13% so that smoke stack emission flue gas becomes saturated flue gas, in the case, both possessed the temperature strip that condensation produces
Part, again with the presence of substantial amounts of moisture, flue gas is run from negative pressure and is changed into operation under positive pressure so that chimney internal condensation process is a large amount of simultaneously
Exist, inner wall of stack surface is covered by dew it is also possible to there be substantial amounts of dew to form reverse water on inner wall of stack surface
Stream, down trickles along inner wall of stack surface.A portion desulfurization fume condensed water, due to the induced effect of high velocity smoke,
Inner wall of stack produces smoke secondary and carries secretly and again become water droplet, and be carried over chimney with high velocity smoke suitable for reading, then fall naturally
Drop down onto the ground around chimney, form " chimney rain " phenomenon, particularly when local temperature, air pressure are relatively low or in thick weather
Between section, the dust carrying in flue gas and drop be gathered near chimney, and fall earthward formation " gypsum rain " or acid rain, to power plant and
Surrounding enviroment produce pollution, or even etching apparatus.
Therefore preventing and treating chimney rain phenomenon one side should strengthen demister operational effect, reduces flue gas moisture content, another
Aspect utilizes chimney anticorrosion desulfurizing fly ash opportunity in smoke evacuation system, installs water conservancy diversion drainage device additional to chimney inside, by effective
Drain reduces reentrainment phenomenon to be occurred.
Utility model content

Spiral stream guidance groove is connected by three-way interface with ACID.
The beneficial effects of the utility model：Using the advantage in chimney anticorrosion engineering construction, using identical with base material
Material be configured guiding gutter, on the one hand can carry out effective water conservancy diversion, combing to flue gas, simultaneously by condensation acid solution received
Collection collects discharge, effectively prevents flue gas acid solution reentrainment phenomenon, can effectively reduce Gypsum Fibrosum rainfall, surrounding enviroment is produced good
Good impact, this construction technology is simply effectively combined with antiseptic project, has good engineering economy and environmental benefit.With
This water conservancy diversion of Shi Liyong brings flue gas and provides rotation, water conservancy diversion, makes disorderly flowing flue gas carry out regular flow, reduces resistance inside chimney
Power, plays the role of to reduce unit load.
Ground floor spiral stream guidance groove is located at the entrance top of horizontal flue and chimney interface, along along flue entrance along spiral cloth
Put, for collecting the dirty acid solution in flue gas turbulent region, flue gas turbulent region flue gas is carried out rotating for the first time, water conservancy diversion simultaneously, alleviate and exist
During flue gas commutation, the flue gas that causes is run helter-skelter phenomenon；Second layer spiral stream guidance groove is located at the 1/3 of chimney whole height, for flat
Stream area flue gas is strengthened rotating further；Third layer spiral stream guidance groove is located at the 2/3 of chimney whole height, for collecting cigarette
Liquid is carried in chimney outlet turbulent flow band inwall condensation secretly, arranges a vertically arranged ACID on chimney internal cylinder outer wall, for collecting,
Conveying condensation acid solution is in the acid baths such as desulfurization melt pit.
