Background technology
In the power boiler flue gas desulphurization system, before former flue gas enters the absorption tower,, reduce water consumption in order to guarantee the absorption efficiency on absorption tower, need be to former flue gas cool-down; And before going smoke stack emission from the clean flue gas that comes out in the absorption tower, need to strengthen plume by heating again to promote and Pollutants Diffusion, prevent or reduce corrosion system downstream equipment.Conventional gas-to-gas heat exchanger needs auxiliary power consumption, belongs to moving equipment, and the existence of rotatable parts causes the burn into blowby, dust stratification of equipment etc. phenomenon is staggered taking place, and makes that the clean flue gas after the desulfurization is contaminated, thereby influences the desulfuration efficiency of whole system.
Summary of the invention
The purpose of this utility model then is the actual conditions at above-mentioned application, has designed a kind of flue gas desulfurization integrated thermal GGH, has the characteristics of high leakproofness, corrosion resistance and easy-to-clean ash.
The purpose of this utility model can reach by following measure:
A kind of flue gas desulfurization integrated thermal gas-to-gas heat exchanger comprises housing 1 and the heat pipe 2 that sets within it, and also is provided with dividing aperture plate 3 in the housing 1, it is characterized in that aperture plate 3 adopts linear sealing 4 and O type circle to seal the form that 5 two kinds of structures combine.
The purpose of this utility model can also reach by following measure:
Be provided with back 6 in the described aperture plate 3, aperture plate 3 contacts with the line on back 6 surfaces and forms linear sealing 4; Aperture plate 3 and back 6 surfaces by be arranged in back 6 grooves O type circle mutually mediate contact form O type circle sealing 5.
The utility model is according to the arrangement requirement at GGH scene, can adopt vertical, horizontal or is in tilted layout.Former flue gas and clean flue gas are separated by the aperture plate in the housing 13, in order to guarantee the high leakproofness of former flue gas and clean flue gas, avoid because of leakage makes clean flue gas be subjected to the pollution of former flue gas, aperture plate has adopted linear sealing 4 and O type circle as shown in Figure 2 to seal the form that 5 two kinds of structures combine.Reliable for what further guarantee to seal, according to the vertical, horizontal of integrated thermal GGH or the difference that is in tilted layout, the structure that can adopt spring compression or tension in the top or the bottom of heat-pipe elements.
Because low-temperature dew point corrosion is remarkable especially in the flue gas desulphurization system, in order to prevent the corrosion of integrated thermal GGH under environment for use, the utility model has adopted following technological means:
1, heat exchange element---heat pipe 2 anticorrosion
(1) heat pipe parent tube (containing fin) adopts carbon steel material, and burns plating enamel or pottery at the outer surface of carbon steel material;
(2) heat pipe parent tube (containing fin) adopts ND steel material, perhaps at the outer surface of ND steel material reburn plating enamel or pottery;
(3) heat pipe parent tube (containing fin) adopts the corrosion-resistant stainless steel material.
2, heat exchanger shell 1 is anticorrosion
(1) heat exchanger shell adopts carbon steel material, and sprays anti-corrosion layer at the inner surface of carbon steel material;
(2) heat exchanger shell adopts ND steel material, and perhaps the inner surface at ND steel material sprays anti-corrosion layer again.
For the ease of the deashing of heat pipe GGH, the utility model has adopted such as control methods such as various soot blowers are installed between ash bucket, Tube Sheet of Heat Exchanger row has been set from deashing speed, suitable spacing of fin, the bottom of selection.
The utility model compared with prior art has following significant advantage:
(1) heat transfer efficiency height, the hot and cold side of heat pipe all can adopt the ratio-frequency welding fin reinforcing to conduct heat as required, remedy the weakness that gas-the gas heat exchanger coefficient of heat transfer is low, have both increased heat exchange area, have reduced the quantity of heat exchanger tube, reduce cost; Increase flow disturbance again, improved the heat exchange effect.
(2) avoid the crossfire of cold and hot fluid effectively, every heat pipe all is relatively independent closed cells, and cold and hot fluid is all outer mobile at pipe, and by tight cold and hot fluid is separated of intermediate seal plate.
(3) do not have any rotatable parts, do not have additional power consumption, do not need often to change element,, can not cause smoke spillage and string to leak yet, guarantee ordinary production even there is subelement to damage.
(4) effectively control low-temperature dew point corrosion:, the heat pipe wall temperature is improved by adjusting the heat transfer area ratio of heat pipe radical or the hot and cold side of adjustment heat pipe; Can also adopt various corrosion-resistant measures, effectively reduce the harm of corrosion.
(5) effectively prevent dust stratification: the combination of multiple purge mode reaches the purpose of deashing.
(6) damage of single heat pipe does not influence the normal operation of other heat pipe, can ignore to the influence of whole heat exchange effect simultaneously yet.
(7) occupation area of equipment is little, and flexible arrangement can be tailord at different systems.
(8) equipment investment, installation, maintenance cost are low, do not need additionaling power during operation, and need powerful blower fan and pump to keep during the GGH of other form operation.
Description of drawings
The profile schematic diagram of Fig. 1 when to be that the utility model is vertical arrange.
Aperture plate sealed structural representation when Fig. 2 is the vertical layout of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1: heat pipe GGH mainly is made up of housing 1 and heat pipe 2, wherein the heating section of heat pipe 2 absorbs former flue gas heat, and heat is passed to intraductal working medium by heat pipe wall, working medium heat absorption back boiling and evaporation, change steam into, steam rises to the heat release section of heat pipe 2 under the effect of pressure reduction; The cooling effect of managed outer clean flue gas, the steam condensation is also outwards emitted the latent heat of condensation, and clean flue gas obtains heat, and condensate liquid relies on gravity to get back to heating section.So go round and begin again, former flue gas heat is just passed to clean flue gas, makes clean flue gas obtain heating.
Former flue gas and clean flue gas are separated by the aperture plate in the housing 13, flow through a side of equipment respectively.In order to guarantee the high leakproofness of former flue gas and clean flue gas, to avoid being provided with back 6 in the aperture plate 3 because of leakage makes clean flue gas be subjected to the pollution of former flue gas, aperture plate 3 contacts with the line on back 6 surfaces and forms linear sealing 4; Aperture plate 3 and back 6 surfaces by be arranged in back 6 grooves O type circle mutually mediate contact form O type circle sealing 5.Aperture plate has adopted linear sealing 4 and O type circle as shown in Figure 2 to seal the form that 5 two kinds of structures combine.
