Abstract

The utility model relates to a wet smoke discharging system applicable to wet-process smoke desulfurization and belongs to mechanical equipment. Through the system, a saturated steam distribution pipe, a tower plate layer, a filler layer, a water scrubbing distribution pipe and a dry waste hot air mixer are additionally arranged above a spraying layer of a conventional desulfurization tower; steam is added above the spraying layer in the desulfurization tower, so that a super-saturated steam water environment needed for steam phase change is built, thus congealing and enlarging small colloidal particles carried by saturated smoke in the tower to be removed; by scrubbing the saturated smoke with water, the temperature of the saturated smoke is reduced, and about 10% of content of water in the smoke is removed; then dry waste hot air is introduced and used for heating the low-temperature smoke, thus increasing the temperature of the smoke, enabling the smoke to be in an unsaturated state and discharging the smoke. By adopting manners of congealing and removing the colloidal particles, firstly cooling and then heating, most of colloidal particles in the desulfurization tower are captured and refluxed, thereby avoiding secondary pollution of solid particles in wet-process desulfurization and solving the problem of rain generated by a smoke plume of a wet chimney.

Description

A kind of wet flue gas exhaust system for wet process of FGD
Technical field
The utility model relates to a kind of wet flue gas exhaust system for wet process of FGD, belongs to plant equipment class.
Background technology
At present, power plant, the most flue gas desulfurization of sintering plant adopt wet desulphurization.Because air heater GGH fault rate is higher, all cancel air heater GGH from newly-built wet desulphurization device in 2006, adopt the wet saturated in line mode of chimney,, also therefore there are some new problems in approximately 50 ~ 60 ℃ of the wet in line temperature of chimney.Owing to having cancelled air heater GGH, the in line flue gas of desulfurization is saturation state, and saturated flue gas because the variation of pressure and temp, before flue gas spreads apart, occurs " raining " phenomenon, causes " secondary pollution " of surrounding environment in atmosphere.Existing desulfurizing tower is due to design and structural reason, and conventional desulfurizing tower spraying layer top directly arranges horizontal demister, still due to the technical limitations of demister, and the colloidal solid very obstinate that particle diameter is less, the outer row's problem of aerosol is serious.
Summary of the invention
For the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of not to be affected on the basis of desulfurizer major project, the discharge of desulfurizing tower spraying layer top is transformed, remove the aerosol in discharged gas fume by saturated Transformation Principle, mode by first cooling rear heating changes saturated flue gas into unsaturated fume emission, has solved respectively the outer row of aerosol and the rainy problem of saturated flue gas.
For achieving the above object, technical solution of the present utility model is:
A kind of wet flue gas exhaust system for wet desulphurization, comprise desulfurization tower body and be arranged on the spraying layer in desulfurization tower body, horizontal demister and wet chimney, saturated vapor distributor pipe is set above described spraying layer, saturated vapor distributor pipe top arranges column plate layer, column plate layer top arranges packing layer, packing layer top arranges washing distributor pipe, dry used heat air mixer is arranged between horizontal demister and wet chimney, the outlet of column plate layer is connected with washing circulating tank entrance by pipeline, the outlet of washing circulating tank is connected with washing pump intake by pipeline, washing pump discharge is connected with washing distributor pipe entrance by pipeline.
Between described spraying layer and saturated vapor distributor pipe, distance is 2.5 ~ 3.0m.
Owing to having adopted above scheme, a kind of wet flue gas exhaust system for wet process of FGD of the utility model.By saturated vapor distributor pipe is set above spraying layer in desulfurizing tower tower, add appropriate steam, set up the required supersaturated vapor environment of steam phase transforming, make the tiny colloidal solid condensation growth carried secretly in saturated flue gas in tower, sedimentation removes voluntarily.
Continuing the flue gas rising and the circulating cooling system being made up of column plate layer, packing layer, washing distributor pipe, washing circulating tank and washing pump meets, less aerosol particle more thoroughly returns in the washing circulatory system, is 55 ℃ by discharged gas fume temperature from 57 ℃ of coolings simultaneously.Wet flue gas after washing cooling, stops water droplet in flue gas return with horizontal demister.
When wet flue gas enters wet chimney, utilize dry used heat air mixer to pass into a large amount of dry used heat air, in chimney, mix with saturated wet flue gas, whole discharged gas fume temperature is heated to 61 ℃, become unsaturated wet flue gas and drained into outward in atmosphere by the chimney that wets, the generation of having avoided wet chimney plume " to rain ".And the change of this kind of outer row's mode takes full advantage of desulfurizing tower original structure, save the improvement cost of desulfurizing tower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See accompanying drawing
A kind of wet flue gas exhaust system for wet process of FGD, this system is made up of desulfurization tower body 1, spraying layer 2, saturated vapor distributor pipe 3, column plate layer 4, packing layer 5, washing distributor pipe 6, horizontal demister 7, washing circulating tank 8, washing pump 9, dry used heat air mixer 10 and wet chimney 11, and in desulfurizing tower 1, routine is provided with spraying layer 2, horizontal demister 7, wet chimney 11 from the bottom to top.The utility model adopts saturated vapor distributor pipe 3 is set respectively according to the order of sequence between spraying layer 2 and horizontal demister 7, column plate layer 4, packing layer 5, washing distributor pipe 6, described spraying layer 2 tops arrange saturated vapor distributor pipe 3, saturated vapor distributor pipe 3 tops arrange column plate layer 4, column plate layer 4 top arrange packing layer 5, packing layer 5 tops arrange washing distributor pipe 6, dry used heat air mixer 10 is arranged between horizontal demister 7 and wet chimney 11, column plate layer 4 exports by pipeline and is connected with washing circulating tank 8 entrances, the outlet of washing circulating tank 8 is connected with washing pump 9 entrances by pipeline, washing pump 9 exports by pipeline and is connected with washing distributor pipe 6 entrances.Wherein column plate layer 4, packing layer 5, washing distributor pipe 6, washing circulating tank 8 and washing pump 9 are connected by pipeline, form circulating cooling system.
Between described spraying layer 2 and saturated vapor distributor pipe 3, distance is 2.5 ~ 3.0m, passes into 80 ℃ of saturated low-pressure steams by saturated vapor distributor pipe 3 in desulfurizing tower 1, realizes removing of aerosol particle in this region.In the time that flue gas continues to rise, be arranged on circulating cooling system in tower (be connected and form by pipeline by column plate layer 4, packing layer 5, washing distributor pipe 6, washing circulating tank 8 and washing pump 9), wet flue gas is cooled to 55 ℃ from 57 ℃, and further aerosol particle is dissolved in cooling water.After wet flue gas is cooling, the horizontal demister 7 of setting adopts mechanical demister pattern, and above >75um droplet is removed.Finally, in the time that wet flue gas goes out to wet chimney 11,170 ℃ of heated drying air that used heat air mixer 10 is introduced from exterior domain, wet flue gas is in the interior uphill process of wet chimney 11, and wet flue gas is warming up to 61 ℃ from 55 ℃, becomes undersaturated wet flue gas and arranges outward.
