Abstract
The utility model relates to the technical field of flue gas waste heat recovery and utilization, in particular to a flue gas waste heat recovery device. A heat pipe type flue gas waste heat recovery device is mainly used for industries including petroleum, chemical engineering, steel and building materials, and mainly comprises a steam pocket, heat pipes and a smoke box, wherein the heat pipes in the smoke box are used for absorbing the waste heat in flue gas and transmitting the absorbed waste heat into the water in the steam pocket, so that the water is vaporized after being heated, and saturated vapor can be generated for production and life. Due to the influence of factors including the field and the manufacturing cost, the number of the installed heat pipes is limited. Therefore, the heat transfer efficiency of each heat pipe is improved. The heat pipes which are arranged at the cold side and the heat side of the flue gas waste heat recovery device are screwed pipes. The heat exchange area is enlarged by 30-50%, and the heat transfer efficiency is improved by 40%.
Description
Technical field
The utility model relates to the heat recovery technical field in the flue gas, a kind of specifically smoke gas afterheat heat exchanger.
Background technology
The flue gas waste heat recovery device is installed on the furnace flue; The useless flue gas that kiln produces during operation passes through from the equipment smoke box; The waste heat that heat pipe in the smoke box absorbs in the flue gas conducts to the water in the drum, makes the water vaporization of being heated, and produces that saturated vapor supplies to produce and the life use; Thereby substituted original steam boiler, reached energy-saving and cost-reducing effect.Heat pipe-type flue gas waste heat recovery device is mainly used in oil, chemical industry, iron and steel, building material industry; Mainly form by drum, heat pipe and smoke box.The waste heat that heat pipe in the smoke box absorbs in the flue gas conducts to the water in the drum, makes the water vaporization of being heated, and produces that saturated vapor supplies to produce and the life use.This equipment mainly is installed on the flue after the regenerator; The useless flue gas that kiln produces during operation passes through from the equipment smoke box; The waste heat that heat pipe in the smoke box absorbs in the flue gas conducts to the water in the drum, makes the water vaporization of being heated, and produces that saturated vapor supplies to produce and the life use; Thereby substituted original steam boiler, reached energy-saving and cost-reducing effect.But owing to receive place, cost factor affecting, the quantity that heat pipe is installed is limited after all.How to improve every Heat Transfer of Heat Pipe on Heat Pipe efficient, making saves energy and reduce the cost reaches maximum efficiency, is the problem of a need research.Prior art has a kind of heat pipe that has fin, but because fin and heat pipe are not to be overall structure, has defective such as be prone to come off, heat-transfer effect is still unsatisfactory.
Summary of the invention
The purpose of the utility model provides a kind of flue gas waste heat recovery device, can improve existing Heat Transfer of Heat Pipe on Heat Pipe efficient, improves energy-saving and cost-reducing effect.
The technical scheme of the utility model is made up of drum, heat pipe and smoke box; The heat pipe of the hot and cold both sides of recover is screwed pipe.
The utility model is suitable for gas-steam type, air-water type recover.
The utility model advantage be Structure novel reasonable, can increase heat exchange area 30%-50%, improve thermal conductivity efficient 40%, safe and reliable to operation, but the long-time running of continous-stable, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
