Abstract
The utility model relates to a tubular heat exchanger, in particular to spring type tubular heat exchanger with an internal heat exchange pipe, which adopts the insert perturbation enhancing technology to enhance perturbation and reinforce heat transfer. The tubular heat exchanger comprises a casing, an upper sealing head, a lower sealing head, tube plates and a heat exchange pipe, wherein, two ends of the casing are connected with the upper sealing head and the lower sealing head through the tube plates respectively; and the upper end and the lower end of the heat exchange pipe are fixed on the tube plates respectively. The tubular heat exchanger is characterized in that a spring is arranged in the center of the heat exchange pipe; and one end of the spring is fixed on a spring suspensionframe arranged on the end surface of the water inlet of the heat exchange pipe, and the other end thereof adopts a free end and is positioned near the water outlet of the heat exchange pipe. The tubular heat exchanger has the main advantages that through simple structural improvements on a common tubular heat exchanger, better heat transfer enhancement and descaling effects are realized without extra energy supply; besides, the tubular heat exchanger has a simple structure and is convenient to install.
Description
Technical field
The utility model relates to a kind of shell-and-tube heat exchanger, concrete relates to a kind of pipe shell heat exchanger having heat exchange tube embedded with spring, by insert disturbance reinforcement technique to strengthen the disturbance augmentation of heat transfer.
Background technology
In the industrial production, all kinds of heat exchangers are widely used and carry out heat exchange at present, wherein use the most general with shell-and-tube heat exchanger.In order to improve the coefficient of heat transfer of heat exchanger, scientific workers from surface texture strengthen, the insert disturbance is strengthened, many aspects such as vibrating enhanced have been launched research, wherein insert is strengthened mainly to insert silk ribbon, this type of strengthens the most fluctuation pressures that can't effectively utilize in flowing, and the incrustation problem does not still solve.
Summary of the invention
Problem to be solved in the utility model is to propose a kind of pipe shell heat exchanger having heat exchange tube embedded with spring at above-mentioned prior art, it can effectively utilize the flowing pressure pulsatile change and strengthen disturbance, the effect that has the disturbance scale removal simultaneously is with enhanced heat exchange device diabatic process.
The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: heat exchanger tube embedded with spring heat exchanger, include housing, go up low head, tube sheet and heat exchanger tube, the two ends of described housing are connected with last low head via tube sheet respectively, the two ends up and down of heat exchanger tube are separately fixed on the tube sheet, it is characterized in that, the inside of heat exchanger tube is provided with a spring and is arranged in the heat exchanger tube center, one end of spring is fixed on the spring suspension of heat exchanger tube water inlet end face, and the spring other end belongs to free end and is placed near the delivery port of heat exchanger tube.
Press such scheme, the resonant frequency of spring is consistent with fluid pressure ripple frequency by heat exchanger tube or reach unanimity.
Spring described in the utility model is followed principle when carrying out the rigidity selection: satisfy making rigidity value little under the requirement of strength prerequisite as far as possible in the vibration processes; The resonant frequency of spring is selected to follow principle: the resonant frequency of spring is with fluid pressure ripple frequency consistent (the best) by heat exchanger tube or reach unanimity, and the resonant frequency that should guarantee spring at least is in fluid pressure ripple frequency scope; By following above-mentioned two principles, can cause the disturbance of spring resonance enhance fluid by fluid pulsation, reach augmentation of heat transfer, suppress incrustation and scale removal purpose.
Operation principle of the present utility model is: after the fluid that pressure fluctuation changes is flowed into by the tube side inlet, enter each heat-transfer pipe respectively, because the pressure fluctuation frequency of fluid is consistent with the resonant frequency of heat exchanger tube medi-spring or reach unanimity, thereby heat exchanger tube can very fast resonance or be tending towards resonance, and keep this vibrational state; Thereby fluid in the vibration disturbance pipe of spring makes the flow turbulence degree strengthen, thereby augmentation of heat transfer and the old dirt layer that washes away on the heat exchanger tube internal face suppress new dirty layer simultaneously and form.
Major advantage of the present utility model is:
The utility model improves by simple structure at the common tube shell heat exchanger, realizes augmentation of heat transfer and descale effect preferably, and does not need additional energy to supply with, and is simple in structure, easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 be among Fig. 1 heat exchanger tube A to zoomed-in view.
The specific embodiment
Further introduce the utility model below by embodiment, but embodiment can not constitute to restriction of the present utility model.
In Fig. 1-2, heat exchanger tube embedded with spring heat exchanger, mainly form by housing 1, last low head (2,11), tube sheet 4, heat exchanger tube 8 etc., the two ends up and down of its middle shell are connected with last low head via tube sheet respectively, the two ends up and down of heat exchanger tube are separately fixed on the tube sheet, on the heat exchanger tube 8 water inlet end faces spring suspension 10 is installed, spring 9 one ends are suspended on the spring suspension 10, spring 9 other ends belong to free end and are placed near heat exchanger tube 8 delivery ports, and the spring body diameter is littler and be arranged in the center of heat exchanger tube than heat exchanger tube internal diameter.The rigidity of spring 9 and resonant frequency are selected, need with reference to fluid pressure pulsating quantity and ripple frequency in the tube side, its principle of following is, satisfy in the vibration processes and make rigidity value little under the requirement of strength prerequisite as far as possible, the resonant frequency of spring is consistent with fluid pressure ripple frequency by heat exchanger tube or reach unanimity, and the resonant frequency that should guarantee spring at least is in fluid pressure ripple frequency scope; By following above-mentioned 2 principles, can cause the disturbance of spring resonance enhance fluid by fluid pulsation, reach augmentation of heat transfer, suppress incrustation and scale removal purpose.
The fluid of shell side is flowed out by shell side outlet 5 after entering housing by shell side inlet 7; The fluid of tube side is entered in the end socket 2 by tube side inlet 3 earlier, in end socket 2, enter heat exchanger tube 8 after, from heat exchanger tube 8, flow out to again in the end socket 11 of the other end, flow out by tube side outlet 6 at last; Arrow indicates direction among direction that fluid flows in tube side and the shell side such as the figure.
Claims (2)
1, heat exchanger tube embedded with spring heat exchanger, include housing (1), go up low head (2,11), tube sheet (4) and heat exchanger tube (8), the two ends of described housing are connected with last low head via tube sheet respectively, the two ends up and down of heat exchanger tube are separately fixed on the tube sheet, it is characterized in that, the inside of heat exchanger tube is provided with a spring and is arranged in the heat exchanger tube center, one end of spring is fixed on the spring suspension of heat exchanger tube water inlet end face, and the spring other end belongs to free end and is placed near the delivery port of heat exchanger tube.
