Abstract
The invention relates to a heat recoverer, in particular to a heat exchanger in a heat recovery device. The casing pipe shell type heat exchanger comprises a shell. Outer heat exchange pipes are arranged in the shell. Inner heat exchange pipes are arranged in the outer heat exchange pipes. The inner wall of each outer heat exchange pipe and the outer wall of the corresponding inner heat exchange pipe are arranged in a spaced manner. The adopted technical scheme is mainly characterized in that the heat exchange pipes with the small outer diameter are inserted into heat exchange pipes of an original heat exchanger in a penetrating manner, so that the heat exchange area of the heat exchange pipes of the heat exchanger is increased. By the adoption of the casing pipe shell type heat exchanger, on the basis of guaranteeing the size and the structure of the existing heat exchanger, the heat exchange pipes with the small outer diameter are inserted into the heat exchange pipes of the original heat exchanger in the penetrating manner, so that the heat exchange area of the heat exchange pipes of the heat exchanger is increased, heat exchange efficiency is improved, and production cost is reduced.
Description
Technical field
The present invention relates to a kind of heat regenerator, particularly relate to the heat exchanger in a kind of heat reclaim unit.
Background technology
Heat exchanger is mainly made up of housing and the tube bank being arranged in housing, is provided with cooling medium, in order to make heat pass to, from the medium that temperature is higher, the medium that temperature is relatively low, to meet the needs in production technology in housing.The cooling device that the chemical industries such as existing fine chemistry industry, pesticide, medicine use is all the monomer cooler cooling down water or chilled brine, run into the cooling occasion that temperature is relatively low, need to cooling down 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 relatively big (for separate unit chilled brine cooler) of cooling medium, the black brittleness making graphite heat exchange block is more prominent, thus easily caused by the damage of equipment, shorten service life of equipment, the substantial amounts 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, moves at pipe flow, flows out from the outlet of the end socket other end, and this is referred to as tube side；Separately-kind of fluid is entered by the adapter of housing, flows out from another adapter on housing, and 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 cylinder, for the exchange of heat between two media.
Tradition tubular heat exchanger is all based on the conduction of heat inside and outside heat exchanger tube and medium is cooled down or heats as can be seen here, and the total amount of heat exchanger tube becomes the leading factor meeting heat transfer requirements.And the heat exchange area of tradition tubular heat exchanger equipment calculates, it is simply that 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
Summary of the invention
Technical scheme can overcome drawbacks described above, it is provided that a kind of sleeve pipe shell heat exchanger, and its heat exchanger tube that interspersed overall diameter is less in the middle of the heat exchanger tube of original heat exchanger, thus increasing the heat exchange area of this heat exchanger tube.
For achieving the above object, the present invention adopts the following technical scheme that it includes housing, is provided with outer heat exchanger tube in housing, is provided with interior heat exchanger tube in outer heat exchanger tube, and between inwall and the outer wall of interior heat exchanger tube of outer heat exchanger tube, interval is arranged.
The technical scheme that the present invention mainly takes 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 increasing the heat exchange area of this heat exchanger tube.
The present invention 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, between both, magnitude relationship is (D >=D '), it is intended to not affect under the premise of heat exchanger format diameter, improves 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 newly added heat exchanger tube, its increment is 50%.This increment is relevant with overall diameter (the D ') specification of newly added heat exchanger tube, but no matter newly added the overall diameter of heat exchanger tube (D ') specification be how many, and this increment is significant.During specific to practical application, can carry out selecting the overall diameter (D ') of newly added heat exchanger tube according to actual needs.
Preferably, between inwall and the outer wall of interior heat exchanger tube of outer heat exchanger tube, spacing is 2-10cm.
The longitudinal central axis line of outer heat exchanger tube and interior heat exchanger tube is coaxial.
Being respectively provided on two sides with tube sheet in housing, all of tube sheet is all provided with pore, outer heat exchanger tube connects tube sheet by pore.Preferably, it is provided with sealing ring between pore and outer heat exchanger tube.
The sleeve pipe shell heat exchanger of the present invention, ensureing on the basis of 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 increasing the heat exchange area of this heat exchanger tube, improve heat exchange efficiency, reduce production cost.

Fig. 2 is the side cross-sectional views of present invention heat exchanger.
In figure: 1-housing；The outer heat exchanger tube of 2-；Heat exchanger tube in 3-；4-tube sheet.
Detailed description of the invention
As it is shown in figure 1, the sleeve pipe shell heat exchanger of the present invention, including housing 1, being provided with outer heat exchanger tube 2 in housing 1, be provided with interior heat exchanger tube 3 in outer heat exchanger tube 2, between inwall and the outer wall of interior heat exchanger tube 3 of outer heat exchanger tube 2, interval is arranged.Being respectively provided on two sides with tube sheet 4 in housing 1, all of tube sheet is all provided with pore, outer heat exchanger tube 2 connects tube sheet 4 by pore.It is provided with sealing ring between pore and outer heat exchanger tube 2.
As in figure 2 it is shown, spacing is 5cm between the inwall of outer heat exchanger tube 2 and the outer wall of interior heat exchanger tube 3.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, need hot-fluid Jie of cooling by filling the heat exchange space of cold flow medium, thus make to need the hot-fluid medium of cooling to transmit and carry out bilateral heat exchange in the gap of internal-external heat exchanger pipe and cooled down.Need the cold flow medium of heating by filling the heat exchange space of hot-fluid medium, thus make to need the cold flow medium of heating to transmit and carry out bilateral heat exchange in the gap of internal-external heat exchanger pipe and heated.
