Description
Technical field
The utility model relates to chimney design technical field, particularly relates to a kind of Wet chimney smoke deflector top condensed fluid collection device, adopts Wet chimney " chimney rain " phenomenon of wet desulfurizing process to administer for industries such as thermal power plant, chemical industry, metallurgy.
Background technology
Wet desulfurization of flue gas by limestone-gypsum method technique is that world is applied at most and the most ripe technique, is also the leading technique of domestic thermal power plant desulfurization.The fired power generating unit of China more than 300MW is more than 90% employing wet desulfurization of flue gas by limestone-gypsum method (WFGD) technology, in Limestone-gypsum Wet Flue Gas Desulfurization Process system, absorption tower exit gas temperature is at about 50 DEG C, and China " Coal,steam plant with FGD designing technique code " (DL/T5196-2004) regulation " under design conditions, the flue-gas temperature of desulfurization after funnel entrance generally should reach more than 80 DEG C discharges ", so early stage WFGD system of installing is substantially all supporting flue gas heat-exchange unit (Gas-gas heater, GGH).But in actual motion, GGH parts there will be the problems such as serious burn into heat exchange element blocking, affect the safe and stable operation of WFGD system.In view of " Coal,steam plant with FGD designing technique code " " meeting environmental requirement and chimney and flue had perfect anticorrosion and drainage measure and also can not establish flue gas heat-exchange unit when technology and economy comparison is reasonable ", so the WFGD system of late design seldom installs GGH, original WFGD system also starts to cancel GGH device.
In actual moving process, without GGH the saturated neat stress of WFGD system directly by Wet chimney discharged to air time, easily produce " chimney rain " or acid mist sedimentation phenomenon, bring new environmental issue." chimney rain " or the genetic analysis of acid mist sedimentation phenomenon are as follows:
(1) flue gas carry liquid secretly
Former flue gas washs through spraying layer, and after demister demist, from absorption tower outlet, through connecting the process of discharging flue to chimney top, being less than the drop of 50um diameter, discharging with flue gas stream.
(2) condensate liquid of flue gas
Former flue gas washs through spraying layer, and after demister demist, from absorption tower outlet, through connecting flue to the process of chimney lining top discharge, usually has the temperature drop of 0.5 ~ 1.0 DEG C, thus result in flue gas saturated-condensation creates droplet.
(3) smoke secondary carries liquid secretly
The drop that the drop taken away from demister and condensation produce, can at region clusterings such as chimney/flue inner wall, chimney entry bottom.Along with the continuous deposition of drop, they just can be subject to the downward pulling force of self gravitation, simultaneously, flue gas also can apply one and the unidirectional pulling force of flue gas stream to liquid, when the power from flue gas reaches or exceed the adhesive force of drop self gravitation and inner surface, liquid reenters or is entered flue gas stream by reentrainment and be entrained with chimney.
Chimney entrance structure more complicated, especially after smoke deflector is set, because the flowing space narrows, this region flue gas flow rate increases sharply, be easy to eddy generation phenomenon, and cause condensate liquid to be carried secretly by smoke secondary being disposed in air, usually comparatively large by the condensing droplet particle diameter carried secretly away, they are the main causes causing " chimney rain " or acid mist sedimentation phenomenon.
Mostly do not consider during the Wet chimney structural design of current routine that smoke deflector region can eddy generation phenomenon and the wet environment of easy condensation, do not consider that arranging condensed fluid collection device at smoke deflector collects the condensate liquid produced, thus vortex phenomenon and condensate liquid reentrainment phenomenon can not be avoided yet.
