Abstract

The utility model relates to a coil pipe type heat exchanger, comprising a steam inlet main pipe and a water return total pipe. A steam coil pipe is connected between a steam inlet branch pipe and a free end; one end of the steam inlet branch pipe is connected the steam inlet main pipe; both ends of a water return coil pipe are respectively connected with the free end and the water return total pipe. The utility model has the advantages of simple structure and low cost, safety, the descaling is automatic, and the work efficiency of the heat exchanger can be increased.

Description

Tube coil type heat exchanger

The utility model relates to heat exchanger, specifically a kind of tube coil type heat exchanger.

General its heating end of existing heat exchanger is a pressure-bearing drum, the other end then is as heat transfer element by the many heat pipes of filling heat transferring medium, when the processing heat pipe, need and to be evacuated in its pipe, and general factory does not possess the test environment to it, influence the quality of heat pipe, because the problem of water quality after use a period of time, scale formation will occur in the pipe, cause heat exchange property to descend, the thermal efficiency reduces.The pressure-bearing drum of heating end also has the danger of blast if do not reach the pressure-bearing condition when work in addition.

The purpose of this utility model is exactly at above-mentioned prior art deficiency, and a kind of tube coil type heat exchanger of design.

The utility model is simple in structure, and cost is low, and safe and reliable, can automatic desludging, improved the operating efficiency of heat exchanger.

The purpose of this utility model is achieved in that a kind of tube coil type heat exchanger, comprise the admission person in charge, return main, admission coil pipe (2) is connected between admission arm (4) and the free end (5), a wherein end of admission arm (4) connects admission and is responsible for (1), and the two ends of backwater coil pipe (3) are connected with return main (6) with free end (5) respectively.

Admission coil pipe (2) is set to three, and backwater coil pipe (3) is set to one.

Admission coil pipe (2) is identical with the pipe diameter of backwater coil pipe (3).

The utility model is reasonable in design, and is simple in structure, and cost is low, improved the serviceability of heat exchanger, and descale effect is good, safe and reliable.

Fig. 1 is the utility model coil arrangement schematic diagram.

Among the figure, 1, admission is responsible for, 2, the admission coil pipe, 3, the backwater coil pipe, 4, the admission arm, 5, free end, 6, the return main.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in the figure, to organize the hot coil parallel connection is welded between admission arm (4) and the free end (5) more, backwater coil pipe (3) is connected between free end (5) and the return main (6), after the steam among the admission house steward (6) is by admission arm (4), enter in three admission coil pipes (2), because an end of three admission coil pipes (2) and backwater coil pipe (3) all is communicated with free end (5), thereby throttle flow is greater than displacement, and free end (5) is produced pressure, because (1) is responsible in admission and return main (6) is fixed, steam pressure forces free end (5) to be subjected to displacement, thereby drive admission coil pipe (2) and backwater coil pipe (3) and produce physical deformation, incrustation scale comes off in its continuous deformation voluntarily, steam enters and passes through free end (5) again behind three admission coil pipes (2) and enter in the backwater coil pipe (3), enter return main (6) by backwater coil pipe (3), discharge outside the heat exchanger, steam is finished feedwater heat exchange work in the middle of operation again.

Claims

1, a kind of tube coil type heat exchanger, comprise the admission person in charge, return main, it is characterized in that admission coil pipe (2) is connected between admission arm (4) and the free end (5), a wherein end of admission arm (4) connects admission and is responsible for (1), and the two ends of backwater coil pipe (3) are connected with return main (6) with free end (5) respectively.

2, tube coil type heat exchanger according to claim 1 is characterized in that admission coil pipe (2) is set to three, and backwater coil pipe (3) is set to one.

3, tube coil type heat exchanger according to claim 1 is characterized in that admission coil pipe (2) is identical with the pipe diameter of backwater coil pipe (3).
