Description

U-shaped heat pipe heat exchanging component and the U-shaped heat exchange of heat pipe integrated with electrostatic precipitator
Technical field
The present invention relates to heat exchange of heat pipe technical field, be specifically related to a kind of U-shaped heat pipe heat exchanging component and the U-shaped heat exchange of heat pipe integrated with electrostatic precipitator.
Background technology
The flue gas of boiler and industrial process is when flowing through heating surface, its heat distribution is subject to certain restrictions, cause air preheater export and deduster entrance flue gas temperature higher, in order to make the heat in flue gas be utilized fully, can be realized by the mode arranging waste-heat recovery device in the exhaust gases passes before deduster entrance horn mouth.But in some cases, limitting by space, flue is arranged extremely compact, between air preheater and deduster entrance horn mouth, lack flue straight section arrange waste-heat recovery device; Although be sometimes designed with flue straight section, owing to arranging Benitration reactor above flue straight section, waste-heat recovery device is extremely restricted.In view of this, this patent proposes waste-heat recovery device to be arranged in deduster entrance horn mouth centre position, reducing flue-gas temperature, can effectively reduce dust ratio resistance by absorbing flue gas heat; Simultaneously because the reduction of flue-gas temperature, the volume flow of flue gas also reduces, and the flue gas flow rate simultaneously entering electrostatic precipitator also reduces, and these 2 kinds of effects can significantly improve the efficiency of dust collection of electrostatic precipitator.
If in the middle of smoke inlet section horn mouth waste-heat recovery device being arranged in electrostatic precipitator, generally select water pipe heat exchanger traditionally, water pipe heat exchanger tube also can be designed to H type, spirality, aciculiform fin, the extended surfaces such as plate shape fin or coupling fin, compact conformation, steel consumption is low, but water pipe Tube Sheet of Heat Exchanger is intrafascicular is filled with liquid-working-medium, once because of after the quick-fried leakage of the tube bank thinning rear generation water pipe heat exchanger of abrasion and corrosion, liquid working substance in whole system reveals the phenomenon that deduster flying dust bleeder valve may be caused to block, the unplanned of equipment is caused to force blowing out, even and if quick-fried leakage occurs heat exchange of heat pipe, because the hydraulic fluid quality of hot casing pack is little, and evaporate rapidly by flue gas, the phenomenon that electrostatic precipitator flying dust bleeder valve blocks can not be caused, avoid cause thus unplanned and force blowing out.
Heat pipe is a high efficiency heat transfer element, its diabatic process make use of the evaporation endothermic of latent heat of phase change in thermal conduction study and two processes the strongest of condensation heat release, have high thermal conductivity, good isothermal, cold and hot both sides heat transfer area can change arbitrarily, can the series of advantages such as remotely transferring, temperature-controllable.The operation principle of heat pipe: heat pipe absorbs flue gas heat in evaporation endothermic end, and transfer heat to intraductal working medium, seethe with excitement after working medium heat absorption or evaporate and change steam into, steam rises to condensation release end of heat under the effect of pressure differential, steam condenses into liquid releasing heat at heat pipe release end of heat, the cold fluid of heating release end of heat outside, and the condensate liquid in pipe after steam heat release is back to evaporation endothermic end by Action of Gravity Field, be pumped into vacuum due to inside or be arranged to certain pressure, so working medium is easy to evaporation and boiling, the startup of heat pipe is very fast.
But heat pipe is commonly straight tube structure in Long-Time Service, filling operation liquid in straight tube, needs two ends soldering and sealing; The heat pipe of straight tube structure, intraductal working medium heat transport limitation is fixed, and can not change operating mode by adaptive temperature; The heat pipe of straight tube structure, in cantilever beam state in heat exchanger, rigidity is little, only adapts to Mini-type heat exchanger, and is not suitable for the heat exchanger structure of the Large-Scale Equipment such as thermal power plant, petrochemical industry; Simultaneously, the heat pipe of single straight tubular construction, need two ends soldering and sealing, when heat exchanger tube is intensive, welding job amount is doubled and redoubled, and the production cycle is long, and the Design and manufacture limiting large shape heat exchange of heat pipe is produced, cause directly-heated pipe for a long time can only be applicable to small size heat exchanger, the maximization of heat exchange of heat pipe is extremely restricted.
