Description
Affiliated technical field
The utility model relate to a kind of for gases and liquids between the heat exchanger of heat exchange.
Background technology
The heat exchanger of heat exchange adopts tubular heat exchanger, coaxial radial heat exchanger, bushing type heat exchange of heat pipe etc. usually between existing for gases and liquids.Weak points such as tubular heat exchanger exists that heat exchange area in the unit volume is less, the weld seam between heat exchanger tube and the tube sheet pulls easily; Coaxial radial heat exchanger is owing to interior pipe and outer coaxial tube, so the heat exchange between the interior pipe outside and the working medium mainly is the heat convection between liquid and the solid wall surface, the coefficient of heat transfer is less than normal; The weld seam of bushing type heat exchange of heat pipe is more, and metal consumption is bigger, and difficulty of processing is also big.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of metal consumption few, and equipment volume is little, and good effect of heat exchange is safe and reliable, and is simple in structure, the two-tube eccentric thermal siphon heat exchanger that seldom keeps in repair and be convenient to keep in repair.
Technical solution of the present utility model:
A kind of two-tube eccentric thermal siphon heat exchanger, its major technique is characterised in that by outer tube (1), interior pipe (2), tube end sheet (3), 180 ° of elbows (4), lower collecting box pipe (5), upper header pipe (6), inner housing (7), insulation material (8), shell body (9) is formed, outer tube (1) adopts finned tube, by outer tube (1), interior pipe (2), tube end sheet (3) is formed single heat exchanger tube, interior pipe (2) is placed on the top of outer tube (1) center line, form two-tube eccentric thermal siphon, adjacent two lists prop up heat exchanger tube and are welded to form a snakelike heat exchange tube by 180 ° of elbows (4) series connection, single heat exchanger tube horizontal positioned, snakelike heat exchange tube is vertically placed, several snakelike heat exchange tubes are connected in parallel, the lower end of the snakelike heat exchange tube that is connected in parallel is connected with lower collecting box pipe (5), the upper end is connected 180 ° of elbows (4) with upper header pipe (6), insulation material (8), upper header pipe (5), lower collecting box pipe (6) is placed between inner housing (7) and the shell body (9).
The utility model adopts that hot gas such as useless flue gas, process gas utilize two-tube eccentric thermal siphon as heat exchanger tube as thermal source in the industrial processes, makes the two-tube eccentric thermal siphon heat exchanger that forms, and is used for heating liquid (being commonly used in adding hot water).
Heat transfer mechanism advanced person of the present utility model, novelty simple in structure, equipment cost is cheap, and is safe and reliable to operation, seldom keeps in repair and is convenient to and keep in repair, and has very high economic benefit and social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that the list among Fig. 1 props up heat exchanger tube (being two-tube eccentric thermal siphon).
As Fig. 1, Fig. 2, the utility model is made up of outer tube 1, interior pipe 2, tube end sheet 3,180 ° of elbows 4, lower collecting box pipe 5, upper header pipe 6, inner housing 7, insulation material 8 and shell bodies 9.
The specific embodiment
The list of being made up of outer tube 1, interior pipe 2 and tube end sheet 3 props up heat exchanger tube and two-tube eccentric thermal siphon by horizontal positioned.For increasing heat exchange area, outer tube 1 wherein is generally finned tube.Walk hot gas outside the outer tube 1, walk liquid in the interior pipe 2.Be evacuated earlier between outer tube 1 and the interior pipe 2, charge and discharge suitable working media again.Adopt some lists to prop up heat exchanger tube and several 180 ° of elbows 4, carry out series welding and be connected into snakelike heat exchange tube, vertically place, its lower end is connected with lower collecting box pipe 5, and the upper end is connected with upper header pipe 6.Weld seam between 180 ° of elbows 4 and the interior pipe 2 is placed on outside the inner housing 7, its objective is to be convenient to make, and is convenient to leak detection, is convenient to maintenance.Even this weld seam is seepage once in a while, can not enter yet and contact with hot gas in the inner housing, guarantee safe and reliable to operation.According to design parameter, adopt some snakelike heat exchange tube parallel connections to be welded between lower collecting box pipe 5 and the upper header pipe 6.Lower collecting box pipe 5, upper header pipe 6 and 180 ° of elbows 4 all are installed between inner housing 7 and the shell body 9, and fill insulant material 8, to reduce heat waste.
In the utility model when work, flow into lower collecting box pipe 5 with cold liquid earlier, flows into each snakelike heat exchange tube more respectively and be heated, and imports outflow heat exchangers in the upper header pipe 6 thereafter.Hot gas enters heat exchanger from the hot gas inlet on heat exchanger top, just with outer tube 1 heat exchange, and the working media in the heating outer tube 1, make it to be vaporized into steam, pipe 2 cold tube wall and produce condensing heat-exchange in working substance steam runs into, pipe 2 in also having the partially liq working media to splash simultaneously to wash away and heat convection takes place has greatly improved integrated heat transfer coefficient, manage the liquid in 2 in the efficient heating, reach the purpose of enhanced heat exchange.Realize the high efficient heat exchanging between gas and the liquid.
