Description
Technical field
The utility model belongs to flue gas waste heat recovery field, relates to a kind of heat transmission equipment.
Background technology
Existing heat pipe preheater, can not tolerate (the SO in the dew point corrosion of low-temperature flue gas and flue gas
x, NO
x, CO
x) sour gas corrosion, or its tolerance is poor.
Can only reclaim the waste heat in higher cigarette temperature (being greater than 120 DEG C) at present, smoke temperature is low again, easily at heat exchanger tube surface sweating, and (the SO thereupon in flue gas
x, NO
x, CO
x) sour gas is dissolved in condensation and forms diluted acid; Exchange heat pipe produces strong corrosion, greatly shortens the life-span of equipment, or is the life-extending stainless steel adopting costliness, adds the manufacturing cost of equipment.
Utility model content
The utility model is for solving the problems of the technologies described above, and the utility model provides a kind of light pipe heat exchanger tube and heat pipe preheater, and it has corrosion-resistant and cost-effective advantage.
To achieve these goals, the utility model adopts following technical scheme.
A kind of light pipe heat exchanger tube, comprise light pipe heat exchange pipe body, described light pipe heat exchange pipe body comprises relative flue gas heat exchange end and air heat-exchange end, described flue gas heat exchange end and smoke contacts, and air heat-exchange end contacts with air, and described flue gas heat exchange end has warded off glassy layer.
A kind of heat pipe preheater, comprise above-mentioned light pipe heat exchanger tube, described heat pipe preheater also comprises into mouth, outlet flue, inlet of cold air, hot air outlet, and described flue gas flows to outlet flue from entering mouth, and described air flows to hot air outlet from inlet of cold air.
The utility model is applied to boiler of power plant flue gas waste heat recovery, fires last layer glass at heat pipe and smoke contacts end surface, utilizes the superpower acid-resistant corrosion of glass, prevent low-temperature flue gas waste heat reclaim in low temperature resistant dew point corrosion and flue gas in (NO
x, CO
xwith SO
x) corrosion of sour gas.
The utility model comprises following beneficial effect: in heat pipe-type air preheater, and heat pipe and smoke contacts end surface fire last layer glass, utilizes the superpower acid-resistant corrosion of glass, solves material corrosion resistance, increases equipment life.Certainly, implement arbitrary product of the present invention might not need to reach above-described all advantages simultaneously.
