Description
Technical field
The utility model relates to a kind of heat regenerator, particularly relates to the heat exchanger in a kind of heat reclaim unit.
Background technology
Heat exchanger forms primarily of housing and the tube bank be arranged in housing, is provided with cooling medium, to make heat pass to the lower medium of temperature from the medium that temperature is higher, to meet the needs in production technology in housing.The cooling device that the chemical industry such as existing fine chemistry industry, agricultural chemicals, medicine uses be all the monomer cooler of cooling water or chilled brine, run into the cooling occasion that temperature is lower, need cool by two devices in series, First equipment cooling water temperature, second equipment chilled brine is lowered the temperature.Its advantage is that heat-transfer effect is better, but due to the temperature difference comparatively large (for separate unit chilled brine cooler) of cooling medium, make the black brittleness of graphite heat exchange block more outstanding, thus easily cause the damage of equipment, shorten service life of equipment, a large amount of low-temperature receiver also wasted.
Tubular heat exchanger is when carrying out heat exchange, and a kind of fluid is entered by the connecting piece of end socket, and in pipe flowing, flow out from the outlet of the end socket other end, this is referred to as tube side; Separately-kind of fluid is entered by the adapter of housing, and flow out from another adapter on housing, this is called shell side.Carry out wall-type heat exchange by heat exchanger tube between tube side and shell side, so heat exchanger tube is main heat transfer parts in tubular heat exchanger, be placed within cylindrical shell, for the exchange of heat between two media.
As can be seen here traditional tubular heat exchanger be all based on heat exchanger tube inside and outside heat transfer medium is cooled or heats, the total amount of heat exchanger tube becomes the leading factor meeting heat transfer requirements.And the heat exchange area of traditional tubular heat exchanger equipment calculates, be exactly the external surface area sum of all heat exchanger tubes in spacing inside two tube sheets:
The quantity (root) of n=pipe
Spacing (rice) inside L=two tube sheet
D=heat exchanger tube overall diameter (rice)
F=heat exchanger heat exchange area (square metre)
F＝n*L*3.14*D
Utility model content
The technical solution of the utility model can overcome above-mentioned defect, provides a kind of sleeve pipe shell heat exchanger, its heat exchanger tube that interspersed overall diameter is less in the middle of the heat exchanger tube of original heat exchanger, thus increases the heat exchange area of this heat exchanger tube.
For achieving the above object, the utility model adopts following technical scheme: it comprises housing, is provided with outer heat exchanger tube in housing, is provided with interior heat exchanger tube in outer heat exchanger tube, and between the inwall of outer heat exchanger tube and the outer wall of interior heat exchanger tube, interval is arranged.
The technical scheme that the utility model is mainly taked is: the heat exchanger tube that the overall diameter that interts in the middle of the heat exchanger tube of original heat exchanger is less, thus increases the heat exchange area of this heat exchanger tube.
The utility model can make the quantity of pipe double, the overall diameter of the heat exchanger tube newly increased (D ') specification is different from the overall diameter (D) of original heat exchanger tube, its between the two magnitude relationship be (D >=D '), under being intended to not affect the prerequisite of heat exchanger format diameter, improve the heat-transfer surface accumulated amount in heat exchanger unit space.Now heat exchanger heat exchange area is calculated as:
The quantity (root) of n=same specification pipe
Spacing (rice) inside L=two tube sheet
D=heat exchanger tube overall diameter (rice)
D '=heat exchanger tube overall diameter (rice)
F=heat exchanger heat exchange area (square metre)
F＝n*L*3.14*D+n*L*3.14*D’
Now heat exchange area is (D '/D) %, such as former heat exchanger tube D=0.038m compared with the heat exchange area increment of traditional heat exchangers, and during overall diameter the D '=0.019m of the new heat exchanger tube added, its increment is 50%.This increment is relevant with overall diameter (the D ') specification of the new heat exchanger tube added, but no matter newly overall diameter (the D ') specification of the heat exchanger tube of interpolation is how many, and this increment is significant.During specific to practical application, can carry out selecting the overall diameter (D ') of the new heat exchanger tube added according to actual needs.
Preferably, between the inwall of outer heat exchanger tube and the outer wall of interior heat exchanger tube, spacing is 2-10cm.
The longitudinal central axis line of outer heat exchanger tube and interior heat exchanger tube is coaxial.
Both sides in housing are respectively equipped with tube sheet, and all tube sheets are all provided with pore, and outer heat exchanger tube connects tube sheet by pore.Preferably, sealing ring is provided with between pore and outer heat exchanger tube.
Sleeve pipe shell heat exchanger of the present utility model, on the basis ensureing existing heat exchanger volume and structure, the heat exchanger tube that the overall diameter that interts in the middle of the heat exchanger tube of original heat exchanger is less, thus increase the heat exchange area of this heat exchanger tube, improve heat exchange efficiency, reduce production cost.

Detailed description of the invention
As shown in Figure 1, sleeve pipe shell heat exchanger of the present utility model, comprises housing 1, is provided with outer heat exchanger tube 2 in housing 1, is provided with interior heat exchanger tube 3 in outer heat exchanger tube 2, and between the inwall of outer heat exchanger tube 2 and the outer wall of interior heat exchanger tube 3, interval is arranged.Both sides in housing 1 are respectively equipped with tube sheet 4, and all tube sheets are all provided with pore, and outer heat exchanger tube 2 connects tube sheet 4 by pore.Sealing ring is provided with between pore and outer heat exchanger tube 2.
As shown in Figure 2, between the inwall of outer heat exchanger tube 2 and the outer wall of interior heat exchanger tube 3, spacing is 5cm.The longitudinal central axis line of outer heat exchanger tube 2 and interior heat exchanger tube 3 is coaxial.
Gap between outer heat exchanger tube 2 and interior heat exchanger tube 3 forms heat exchange space, the heat exchange space needing the hot-fluid of cooling to be situated between by filling cold flow medium, so just makes to need the hot-fluid medium of cooling to transmit in the gap of internal-external heat exchanger pipe and carry out bilateral heat exchange and is cooled.Needing the cold flow medium of heating by filling the heat exchange space of hot-fluid medium, so just making to need the cold flow medium of heating to transmit in the gap of internal-external heat exchanger pipe and carry out bilateral heat exchange and being heated.
