Description
Technical field
The present invention relates to the integrated recovering device of a kind of card Linne type industrial exhaust heat, specifically belong to the energy-conserving and environment-protective technical field.
Background technique
Industrial processes meetings such as station boiler, industrial boiler, industrial furnace and chemical plant produce waste gas, waste water, waste vapour, waste residue etc., wherein contain a large amount of unemployed heats.As giving off a large amount of flue gases in the station boiler production process, wherein the heat of recyclable utilization is a lot; Also need in the station boiler running to ensure that by continuous blowdown and periodical blowdown the water quality of boiler meets demand for security, must remove the oxygen in the boiler feed water, to avoid the corrosion to steam generator system simultaneously.Thermal deaerator is the one preferred technique of station boiler at present, and oxygen-eliminating device is carried a large amount of working steams secretly and entered atmosphere in work.Owing to contain a large amount of heats and good water quality in boiler platoon water and the deaerator exhaust,, and environment polluted if directly discharging will cause the great energy and the wasting of resources.
The device flow process that ZL200710046604.X provides a kind of residual heat from boiler fume to reclaim, this technology main application fields is a utility boiler.This technology is the good method that a kind of boiler afterheat reclaims.But, what this heat recovery flow process produced is low-grade low pressure steam, if and the steam that produces is as can't be outward for use, this The Application of Technology promptly is very restricted, usually only can be by increasing air preheater or feed water preheater recovery section fume afterheat, the temperature of exhaust fume of boiler is still higher, and energy dissipation is still bigger, does not meet energy-conservation requirement.
