Description
Technical field
The present invention relates to heat-exchanger rig, be specifically related to a kind of desulphurization system swinging gas-gas heat exchanger.
Background technology
Swinging gas-gas heat exchanger (Gas Gas Heater) is called for short GGH, the GGH majority that present Chinese desulphurization system is used all is the technology of introducing external (U.S., Germany, France), all exists the higher problem of air leak rate of air curtain in the various swinging GGH that introduce.The air leak rate of air curtain guarantee value is at 0.5-1%, and air leak rate of air curtain often can't reach best guarantee value during practical application, statistical test as a result display effect preferably the GGH air leak rate of air curtain also can only reach 0.8%, minimum can only reach 0.6%, has a strong impact on the operating efficiency of desulphurization system.
Summary of the invention
The purpose of this invention is to provide that a kind of air leak rate of air curtain is low, the low leakage swinging gas-gas heat exchanger of high efficiency.
Technical solution of the present invention is: it comprises cylindrical housing and is installed in the cylindrical rotor of the rotation on the supporting member, in the former exhaust gases passes of shell, purge wind be blown into from bottom to top rotor-position below be provided with some with purge the division boards that the wind outlet is parallel, prevention comes the purging wind of self-cleaning flue gas to mix with former flue gas; In the former exhaust gases passes of shell, purge wind blow out from bottom to top rotor-position above be provided with some with purge the wind outlet parallel, stop former flue gas to the isolation deflectors of clean fume side leakage; Former flue gas enters rotor-side, rotor and screws out boundary face position that former exhaust gases passes contact with fan-shaped sealing plate and have additional and prevent that the isolation purging that leaks from sealing wind apparatus in the former exhaust gases passes of the offside of former purging sealing wind apparatus, shell.
Technique effect of the present invention is: it has, and air leak rate of air curtain is low, the advantage of high efficiency, and its air leak rate of air curtain can be down to 0.3-0.5%, reaches level domestic, leading in the world, surpasses the same category of device of external import (U.S., Germany, France).Use it can improve total desulfuration efficiency of desulphurization system, more be conducive to energy-conserving and environment-protective.
