Abstract
The utility model discloses a combined type longitudinal finned tube exhaust gas waste heat exchanger, and particularly relates to the heat exchanger which is used for waste heat using of exhaust gas. The combined type longitudinal finned tube exhaust gas waste heat exchanger comprises a cuboid-shaped heat exchanger shell body. Exhaust gas inlet-outlet openings are arranged at two ends of the heat exchanger shell body. A tube bundle which is formed by longitudinal finned tubes is arranged inside the shell body. The combined type longitudinal finned tube exhaust gas waste heat exchanger is characterized in that a water inlet female tube and a water outlet female tube which are communicated with the inner tubes of the longitudinal finned tubes are placed on the outer side of the shell body, and the longitudinal finned tubes are combined type longitudinal finned tubes which are formed by the fact that steel tubes are sleeved inside aluminum longitudinal finned tubes. Due to the design that the longitudinal finned tubes are formed by attaching of the steel tubes and the aluminum longitudinal finned tubes, the combined type longitudinal finned tube exhaust gas waste heat exchanger has the advantages of being compact in structure, small in resistance, easy to wash, high-pressure resistant and erosion resistant in tube pass. Due to the external female tubes, the size of the heat exchanger is reduced, the inner space of the heat exchanger is fully used, and maintaining is convenient. Due to the fact that an ellipse water distributing tube is used, exhaust gas blocking area is reduced on the condition that tube pass flow amount is not lowered, and accordingly exhaust gas can contact with the finned tubes completely, and resistance is reduced.
Description
Technical field
The utility model belongs to the reinforcement heat exchanger that heat exchange medium does not directly contact, especially for the heat exchanger of fume afterheat utilization.
Background technology
Day by day exhausted along with non-renewable energy resources such as coal, oil and natural gas obtained increasing attention for recycling or the recycle utilization of energy, thereby in technical fields such as coal-burning boiler, metallurgy, the flue gas heat exchange technology is widely used.
The finned tube that present most of flue gas heat-exchange unit uses all is to be made of parent tube and the transverse fin that is distributed on the parent tube.Some parent tubes and fin are respectively steel pipe and steel disc, and some parent tubes are steel pipe, and fin is aluminium flake, generally adopt the welding of fin and parent tube or canoe that fin is fixed on the parent tube, process loaded down with trivial details.Because the lateral arrangement parent tube, its heat exchanger resistance is easy cleaning more greatly and not, and flue gas contains again a large amount of dusts, easily piles up dust finned tube is covered, and has a strong impact on the heat exchanger operating efficiency.Flue-gas temperature is higher simultaneously, and the thin easy distortion of transverse fin, further resistance reduces heat exchange efficiency.The aluminium flake thermal conductivity factor is obviously high than steel disc simultaneously, and weight is light, but rigidity is less than steel disc
Our company formerly patent ZL200420024690.6 discloses a kind of longitudinal finned tube flue gas heat exchanger rig, it adopts vertical aluminium fin and parent tube integral body rolling, find that in application its heat transfer effect is good, and resistance is little, the heat exchanger two ends are visual, easy cleaning, be difficult for dust stratification, but withstand voltage, the erosion existing problems of aluminum pipe, and because finned tube is aluminium, female pipe, water inlet pipe, outlet pipe also are aluminium, withstand voltage, erosion property is not good, and connects with exterior line is bad, makes complicated, operation is more, and cost is higher.
The utility model content
For heat exchanger bearing capacity and the poor deficiency of abrasion-resistance that overcomes existing use aluminium fin, make complicated, the utility model provides a kind of combined type longitudinal finned tube smoke gas afterheat heat exchanger, the advantages such as the resistance that this combined type longitudinal finned tube smoke gas afterheat heat exchanger has not only been inherited longitudinal finned tube is little, easy cleaning, and improved bearing capacity and erosion property.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of combined type longitudinal finned tube smoke gas afterheat heat exchanger, smoke entrance is equipped with at the heat exchanger shell two ends that comprise cuboid, the tube bank that is comprised of longitudinal finned tube is housed in the housing, it is characterized in that: the female pipe of water inlet, main water outlet pipe are positioned at hull outside, and described longitudinal finned tube is the combined type longitudinal finned tube that is set with interior steel pipe in the aluminium longitudinal finned tube.
Described smoke entrance for outside flue be the circular flange interface, with the hemispherical dome shape of the housing side of being interface.
The female pipe of described water inlet, main water outlet pipe closed at both ends, female pipe of intaking is provided with water inlet, and main water outlet pipe is provided with delivery port.
The described tube bank that is formed by longitudinal finned tube, the rectangular array distribution of combined type longitudinal finned tube that level is installed, the interior steel pipe two ends of every layer composite longitudinal finned tube are welded on the perpendicular elliptical tube, elliptical tube is horizontally disposed, the support channel-section steel of vertically installing is fixed in elliptical tube by U-bolt and supports on the channel-section steel, elliptical tube near gas approach one end is connected with main water outlet pipe, and the elliptical tube of the other end is connected with the female pipe of water inlet.
Described housing is the cuboid housing that 4 blocks of plates form, and a plurality of channel-section steel reinforcements are arranged outward, and the housing side is provided with access hole, the bottom surface is provided with the cleaning sewage draining exit.
The female pipe of described water inlet bottom is provided with sewage draining exit.
The beneficial effects of the utility model are: because adopt that the vertical finned tube of steel pipe and aluminium pastes that swollen vertical finned tube design has that compact conformation, resistance are little, easy cleaning, tube side be high pressure resistant, erosion resistant advantage; Owing to adopting female pipe external, can reduce heat exchanger volume, take full advantage of space in the heat exchanger, easy access; Owing to adopting oval distributive pipe, reduce flue gas on the basis that does not reduce the tube side flow and stopped area, flue gas is fully contacted with fin, and reduced resistance.
