Working principle:
Sulfur-containing smoke gas enters in spray column from gas inlet, flows up along tower body；Spray pump is by spraying cooling liquid from collection
Each spray equipment is pumped into liquid bath, by spraying after cloth liquid, spraying cooling liquid is in dropping process and the sulfur-bearing cigarette that flows up
Gas generates chemical reaction after being contacted, and sloughs the sulphur content in flue gas；Spraying cooling liquid is increased by flue gas, temperature simultaneously,
Moisture evaporation in spraying cooling liquid forms saturated flue gas, carries out wall-type heat exchange between saturated flue gas and pillow panel cooler,
Flue-gas temperature reduces, and condensed water is precipitated, again returns in spraying cooling liquid, and heat transfer is situated between to the cooling in pillow panel cooler
Matter, coolant temperature are increased, the heat cooled medium recycling in former flue gas.
Saturated flue gas after desulfurization cooling is placed on board for pillow formula reheater in chimney and heats, the humidity of flue gas after heating
It is constant, but relative humidity reduces, and after chimney discharge and atmosphere contact mixing, is still within unsaturated state, white plume
It disappears, achievees the purpose that " disappearing white ".
In spray column, flue gas, spraying cooling liquid, cooling medium and heat medium have carried out the mistake of complicated heat and mass
Journey not only has the direct contact heat transfer of flue gas and spraying cooling liquid, and there are also flue gas, spraying cooling liquid and cooling medium, heating to be situated between
The wall-type heat exchange of matter；Not only there is the gasification of moisture in spraying cooling liquid, there are also the condensations of flue gas, the phase transformation of saturated flue gas reheating
Heat transfer, while being also accompanied by chemical reaction.
In whole process, flue gas has obtained desulfurization, cooling and heating, while water capacity increases, and relative humidity reduces；Board for pillow
Coolant temperature in formula cooler is increased, and waste heat has been recycled；Spraying cooling liquid temperature is first increased and is reduced afterwards, and moisture contains
Amount reduces.
Entire pillow plate heat exchanger is made of the plate package that shell wraps up, and is circulated between shell and plate package for flue gas
Channel, for interchannel away from width, flue gas circulating resistance is small；The circulation passage of cooling (heating) medium in plate side is then by pincushion heat exchanger plates
Cooling (heating) medium inlet and cooling (heating) media outlet manifold integrate cooling medium inlet and cooling medium outlet.
Board for pillow formula heat exchanger structure can be designed according to spray tower structure, on the basis of guaranteeing equipment using effect,
To meet the needs of different size pattern.For cooling (heating) medium inlet and outlet on the outside of tower body, equipment simple installation is quick.
Plate side medium enters pincushion heat exchanger plates to rear, according to the stream pre-set in inner passage from medium inlet
Road is flowed out with low speed turbulent flow state from media outlet pipe.Medium is changed by absorbing or distributing heat to pincushion in flow process
The wall surface of hot plate pair completes the heat exchange of medium and the outer flue gas of plate in plate.
The range of temperature of flue gas can guarantee by the processes of pincushion heat exchanger plates pair and the temperature of circulatory mediator, cigarette
The treating capacity of gas can be adjusted by the quantity and size of pincushion heat exchanger plates pair.
The pattern multiplicity of pincushion heat exchanger plates pair can be made flow channel type, pillow flower pattern etc., and the runner quantity of heat exchanger propels the price of
Highly, the structures such as contour length and width, runner spacing and quantity, media type, the position of inlet and outlet and caliber need to combine
Specific duty parameter and experience accumulation are tightly designed, to guarantee the performance of entire heat exchanger always at concert pitch
Point.
Described in the utility model to disappear white spray column for a kind of flue gas based on pillow plate heat exchanger, the utility model has such as
Lower advantage:
1, pillow plate heat exchanger the plate package being made into is made of a certain number of pincushion heat exchanger plates, the heat exchanger be by
Two metal sheets are superimposed, and are welded together by laser penetration, are expanded between plate pair by high-pressure fluid
And internal heat medium channel is formed, and heat exchanger surface is wave-shaped, and it is very smooth, both meet the requirement of heat transfer enhancing, simultaneously
Cooler resistance is small, and is not easy to generate dirt；
2, pillow panel cooler not only reduces the burden of spray pump and board for pillow formula reheater, equipment overall operation expense drop
It is low；The water consumption of spray column is reduced, while the heat recovery of flue gas can also be utilized into cooling medium；
3, the flue gas after the heat treatment of board for pillow formula reheater, improves the bearing capacity of vapor in flue gas, thoroughly eliminates cigarette
Chimney outlet carries denouncing for white plume；
4, the cooling medium and flue gas rested the head in panel cooler are in reverse flow, and heat exchange efficiency is high, and heat transfer temperature difference is small, heat exchange
Cooling medium grade afterwards is higher, and heat recovery rate is high；
5, pillow plate heat exchanger (cooler and reheater) is modularized design, vertical installation, compact-sized, occupied area
It is small, the structure and performance of original spray column are not influenced, and adaptability for working condition is strong.
