Abstract
The invention discloses a combined type longitudinal finned pipe fume waste heat exchanger, belongs to a heat exchanger, and especially relates to a heat exchanger used for fume waste heat utilization. According to the combined type longitudinal finned pipe fume waste heat exchanger, the two ends of a rectangular solid heat exchanger shell are provided with a fume inlet and a fume outlet, and the shell is internally provided with a pipe bundle composed of longitudinal finned pipes. The combined type longitudinal finned pipe fume waste heat exchanger is characterized in that a water inlet main pipe and a water outlet main pipe communicated with inner pipes of the longitudinal finned pipes are positioned at the outer side of the shell, and the longitudinal finned pipes are combined type longitudinal finned pipes that steel pipes are sleeved in aluminium longitudinal finned pipes. The longitudinal finned pipe design that steel pipes are in expansion fit with aluminium longitudinal finned pipes, the heat exchanger has the advantages that the structure is compact, the resistance is small, the cleaning is easy, a pipe side can resist high pressure and resist ablation; the main pipe is arrange externally, the volume of the heat exchanger is reduced, the space in the heat exchanger is fully utilized, and the heat exchanger is easy to overhaul; and an ellipse diversion pipe is adopted, the fume blocking area is reduced on the condition that the flow of the pipe side is not reduced; the fume fully contacts with fins and the resisting force is reduced.
Description
Technical field
The invention 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
Exhausted day by day along with non-renewable energy resources such as coal, oil and natural gas obtained increasing attention for the recycling or the recycle utilization of energy, thereby in technical fields such as coal-burning boiler, metallurgy, the flue gas heat exchange technology obtained using widely.
The finned tube that present most of flue gas heat exchange device uses all is to be made up of parent tube and the transverse fin that is distributed on the parent tube.Parent tube that has and fin are respectively steel pipe and steel disc, and the parent tube that has is a steel pipe, and fin is an aluminium flake, generally adopt welding of fin and parent tube or canoe that fin is fixed on the parent tube, process loaded down with trivial details.Because lateral arrangement parent tube, its heat exchanger resistance are big and be difficult for cleaning, flue gas contains a large amount of dusts again, piles up dust easily 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 deformation 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 smoke heat replacing device, and it adopts vertical aluminium fin and parent tube integral body rolling, finds that in application its heat exchange is respond well; And resistance is little, and the heat exchanger two ends are visual, is prone to clean; Be difficult for dust stratification, but withstand voltage, the erosion existing problems of aluminum pipe, and because finned tube is an aluminium; Female pipe, water inlet pipe, outlet pipe also are aluminium, and be withstand voltage, erosion property is not good, and connect with exterior line is bad; Make complicacy, operation is more, and cost is higher.
Summary of the invention
For the heat exchanger bearing capacity that overcomes existing use aluminium fin and the deficiency of abrasion-resistance difference; Make complicated; The present invention provides a kind of combined type longitudinal finned tube smoke gas afterheat heat exchanger; Advantages such as little, the easy cleaning of the resistance that this combined type longitudinal finned tube smoke gas afterheat heat exchanger has not only been inherited longitudinal finned tube, and improved bearing capacity and erosion property.
The technical solution adopted for the present invention to solve the technical problems 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 of being made up 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 of steel pipe in being set with 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, the female pipe of water inlet is provided with water inlet, and main water outlet pipe is provided with delivery port.
The described tube bank of forming 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, the elliptical tube horizontal arrangement, and the support channel-section steel of vertically installing is fixed in elliptical tube through 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 are formed, and a plurality of channel-section steel reinforcements are arranged outward, and 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 invention has the beneficial effects as follows: since the vertical finned tube design of adopting the vertical finned tube of steel pipe and aluminium to paste to expand have compact conformation, resistance little, be prone to cleaning, tube side is high pressure resistant, erosion resistant advantage; Owing to adopt female pipe external, can reduce heat exchanger volume, make full use of space in the heat exchanger, easy access; Owing to adopt oval distributive pipe, on the basis that does not reduce the tube side flow, reduce flue gas and stopped area, flue gas is fully contacted with fin, and reduced resistance.
