Description
Technical field
The utility model relates to a kind of heat exchanger.Be the tube coil type heat exchanger on the overflow dyeing machine that is used for dyeing liquor is heated specifically.Also can be used for industries such as medicine, chemical industry heats various liquid mediums.
Background technology
China No. 200410065977.8 patent disclosures a kind of liquid heating arrangement for dyeing.This heater contains a heat exchanger, and this heat exchanger is made up of tubular shell, tube sheet and some heat exchanger tubes.The tubular shell two ends have medium import and media outlet respectively.Said tube sheet and heat exchanger tube are in the tubular shell.Tube sheet wherein has two, and they leave spacing respectively and between the two ends of tubular shell inner chamber, around them all with the inwall sealing-in mutually of tubular shell, be processed with the through hole of mutual correspondence above them.Insert respectively in the respective through hole on two tube sheets at the two ends of heat exchanger tube, and sealing-in mutually between the through hole on the end lateral surface that makes heat exchanger tube and the tube sheet, and the inner chamber of heat exchanger tube is connected with the medium import and the media outlet at tubular shell two ends.Also be provided with two deflectors in the tubular shell between two tube sheets, the shape of this two deflector is identical with the inner chamber cross section of tubular shell, one side at them is cut one respectively, makes them all have scarce limit, so that make the tubular shell intracavity inter-connection of deflector both sides.Said two deflectors go to upper and lower alternately shape along the inner chamber of tubular shell and arrange, the deflector edge outside the deferrization limit all welds together with the inwall of tubular shell.Be processed with some through holes on the deflector, some heat exchanger tubes penetrate one by one and are welded in these through holes.On the barrel at tubular shell two ends, be processed with heat conductive oil inlet and outlet respectively.During work, enter in the tubular shell from heat conductive oil inlet,, discharge from the conduction oil outlet of the tubular shell other end, thereby the dyeing liquor of process in heat exchanger tube is heated through the guiding of two deflectors through the conduction oil that heats.Though adopt above-mentioned heat exchanger can realize dyeing liquor is heated, have following problem; The one, because this heat exchanger is made up of tubular shell, tube sheet and some heat exchanger tubes, all be to adopt welding manner to be connected usually between the two ends of some heat exchanger tubes and two tube sheets, the conduction oil that enters in the course of work in the tubular shell can make tubular shell and tube sheet dilatancy, and then makes and occur crack, oil leakage phenomenon between heat exchanger tube two ends and tube sheet.Therefore, this heat exchanger fails rate height, fragile, service life is not long.The 2nd, during owing to work, conduction oil through heating enters in the tubular shell from heat conductive oil inlet, and after the guiding through two deflectors, i.e. conduction oil outlet from the tubular shell other end is discharged from, the time that conduction oil stops in tubular shell is short, and heat utilization ratio is lower.The 3rd, because heat exchanger tube is a straight tube, its heat exchange area depends on its surface area, and heat exchange area is less, and the time that heated medium stops in heat exchanger tube is shorter.Like this, also can have influence on the raising of heat utilization ratio.
The utility model content
Problem to be solved in the utility model provides a kind of tube coil type heat exchanger.This tube coil type heat exchanger, long service life, heat utilization ratio height.
For addressing the above problem, the utility model is taked following scheme:
Tube coil type heat exchanger of the present utility model comprises tubular shell, and the two ends of tubular shell have medium import and media outlet respectively.Be characterized in that current limiting tube is arranged in the tubular shell, this current limiting tube is parallel with tubular shell.The current limiting tube two ends are closed, there is the several layers coil pipe its outside, one end of the equal self-limiting pipe of this several layers coil pipe is wound into the other end, and between every layer of coil pipe, between internal layer coil pipe and current limiting tube, all leave the gap that heated medium passes through between outer coil pipe and tubular shell inwall.Heat conductive oil inlet and outlet are arranged respectively on the sidewall at tubular shell two ends, and each layer coil pipe two ends are connected with heat conductive oil inlet and outlet respectively.
Inner chamber at central tube has two dividing plates, and two dividing plates are respectively near the two ends of central tube, thereby forms two current-sharing chambeies two first sections of central tube.The two ends of some coil pipes are communicated with two current-sharing chambeies respectively, and the conduction oil import and export also is connected with two current-sharing chambeies respectively, make the conduction oil equalization that enters in three layers of coil pipe.
Take such scheme, have the following advantages:
Because in the tubular shell current limiting tube is arranged, this current limiting tube is parallel with tubular shell.The current limiting tube two ends are closed, there is the several layers coil pipe its outside, one end of the equal self-limiting pipe of this several layers coil pipe is wound into the other end, and between every layer of coil pipe, between internal layer coil pipe and current limiting tube, all leave the gap that heated medium passes through between outer coil pipe and tubular shell inwall.In the course of work, when the coil pipe in the tubular shell was subjected to heating heat-conducting oil generation thermal expansion, coil pipe can extend along with the longitudinal tensile strain of tubular shell, and therefore, this tube coil type heat exchanger fault rate is low, not fragile, long service life.Owing on the sidewall at tubular shell two ends heat conductive oil inlet and outlet are arranged respectively, each layer coil pipe two ends are connected with heat conductive oil inlet and outlet respectively again.Conduction oil flows through from coil pipe, and the length of coil pipe is longer.The length one of coil pipe is long, and the time that conduction oil stops within it is just long, and therefore, it is just high that heat gets utilization rate.
