Description
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 with the integrated U-shaped heat exchange of heat pipe of 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 outlet and deduster entrance flue gas temperature higher, for the heat in flue gas is utilized fully, can realize by the mode of waste-heat recovery device is set in the exhaust gases passes before deduster entrance horn mouth.But ，Shou space is limit in some cases, flue is arranged extremely compact, lacks flue straight section and arrange waste-heat recovery device between air preheater and deduster entrance horn mouth; Although be sometimes designed with flue straight section,, because Benitration reactor has been arranged in flue straight section top, 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, by absorbing flue gas heat, reduces flue-gas temperature, can effectively reduce dust and compare resistance; Because of the reduction of flue-gas temperature, the volume flow of flue gas also reduces simultaneously, and the flue gas flow rate that simultaneously enters electrostatic precipitator also reduces, and these 2 kinds of effects can obviously improve the efficiency of dust collection of electrostatic precipitator.
If waste-heat recovery device is arranged in the middle of the smoke inlet section horn mouth of electrostatic precipitator, generally select traditionally water pipe heat exchanger, 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 the intrafascicular liquid-working-medium that has been full of of water pipe Tube Sheet of Heat Exchanger, once because occurring after the quick-fried leakage of water pipe heat exchanger after tube bank abrasion and corrosion attenuate, liquid working substance in whole system is revealed the phenomenon that may cause that deduster flying dust bleeder valve stops up, what cause equipment unplannedly forces blowing out, even and there is quick-fried leakage in heat exchange of heat pipe, because of the hydraulic fluid quality of hot casing pack seldom, and be subject to flue gas and evaporation rapidly, the phenomenon that can not cause electrostatic precipitator flying dust bleeder valve to stop up, that has avoided causing thus unplannedly forces blowing out.
Heat pipe is a high efficiency heat transfer element, its diabatic process has been utilized the evaporation endothermic of latent heat of phase change and two processes the strongest of condensation heat release in thermal conduction study, the heat transfer area with high thermal conductivity, good isothermal, cold and hot both sides can change arbitrarily, can remotely transferring, the series of advantages such as temperature is controlled.The operation principle of heat pipe: heat pipe absorbs flue gas heat in evaporation endothermic end, and transfer heat to intraductal working medium, boiling or evaporation after working medium heat absorption and change steam into, steam rises to condensation release end of heat under the effect of pressure differential, steam condenses into liquid state at heat pipe release end of heat and emits heat, the cold fluid of heating release end of heat outside, and the condensate liquid after steam heat release is back to evaporation endothermic end by Action of Gravity Field in pipe, because inside has been pumped into vacuum or has been 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-term use, 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 is cantilever beam state in heat exchanger, and rigidity is little, only adapts to Mini-type heat exchanger, and is not suitable for the heat exchanger structure of the Large-Scale Equipments 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, has limited the Design and manufacture of large shape heat exchange of heat pipe and has 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.
