Description
Technical field
The utility model relates to a kind of aluminium electrolytic flue residual heat using device, makes full use of fume afterheat.
Background technology
The flue gas that produces in the existing aluminum electrolysis process is directly delivered to the chimney emptying by air-introduced machine after dedusting, winter, exhaust gas temperature was 100 ℃, and summer, exhaust gas temperature can reach 120 ℃; The high-temperature flue gas discharging strengthens the service life of having reduced equipment to equipment corrosion; And thermal loss surpasses 5000Kw/h, and energy waste is serious, and is also very big to ambient temperature effect, also is one of reason that causes greenhouse effects.
The utility model content
The purpose of this utility model is to provide a kind of aluminium electrolytic flue residual heat using device, makes full use of fume afterheat, energy-conserving and environment-protective.
Aluminium electrolytic flue residual heat using device described in the utility model, one housing is arranged, the top of housing is provided with the flue connector, the bottom of housing is provided with the air-introduced machine connector, be provided with snakelike conduit in the housing, the outer wall of snakelike conduit is provided with helical fin, and the two ends of snakelike conduit are respectively water inlet end and water side, and water inlet end and water side extend to outside the housing.
During use, directly the utility model is connected between flue and the air-introduced machine and gets final product.Feed cold water from water inlet end, the waste heat of flue gas has directly heated the cold water in the snakelike conduit, thereby the waste heat in the flue gas is fully utilized, and the hot water that flows out from the water side can be directly used in bathing or heating heating etc.Can also be again by the heating of further will feeding water of whole vapour-water heat exchange unit, make its reach 95 ℃ simultaneously return water temperatures reach 70 ℃, pressure reaches more than the 0.4MPa, to guarantee good heating effect.
Snakelike conduit designs in housing and is the laterally tortuous coiling structure of multilayer, has strengthened heat exchange area, and has strengthened heat exchange, heat exchange effect, heat exchange efficiency height.
Situation with our company is adjusted, and after the normal operation of system, approximately can save 10000 tons of steam every year, press 92 yuan of/ton calculating of steam market price, remove the expense of repair and maintenance at ordinary times, annual about 900,000 yuan of the steam expenses of approximately saving have realized subtracting the purpose that can reduce discharging.
The utility model is simple and compact for structure, and is easy to maintenance, good effect of heat exchange, and without any need for exterior power, fault rate is low, the efficient height, thus made full use of fume afterheat, reached the purpose of energy-conserving and environment-protective.The hot water that obtains by heat exchange can be directly used in heating system, carries out the hot water that heat exchange obtains by the secondary water-water heat exchanger simultaneously and can be directly used in bath system.
