The pulsating flow vibrating induction device has the following structure: the pulsating flow vibrating induction device comprises a pulsating flow tube, wherein a plurality of water outlets are arranged on the vibrating flow tube, and a pulsating flow generator is arranged at the end part of the pulsating flow tube.
Description
Technical field
The utility model relates to a kind of elastic tube bundle heat exchanger and flows vibration inducing device with pulsation.
Background technology
Shell-and-tube heat exchanger has very at industrial circles such as energy source and power, petrochemical industries to be used widely, and the enhanced heat exchange technology of heat exchanger is to energy-saving and cost-reducing significant.Wherein the passive facilitation heat transfer technology is current important research direction owing to not needing extraneous high-quality energy input to reach the purpose of enhanced heat exchange.
Utilizing flow-induced heat transfer element vibration realizing enhanced heat exchange is a kind of form of passive facilitation heat exchange, can the strictness that convection cell in the heat exchanger is vibration induced prevent to change into effective utilization to vibration, the convection transfer rate of actuated element under low flow velocity significantly improved, and utilize vibration suppression heat transfer element surface dirt, lower dirtiness resistance, realize compound intensified heat-transfer.
92106727.5) and " elastic tube bundle steam-water heat exchanging group " (application number: 94110563.6) propose a kind of plane elasticity tube bank heat transfer element Chinese invention patent " floating coil-heat tube two-stage heating vapour-water thermal exchanger " (application number:, utilize flow-induced tube bank vibration to carry out enhanced heat exchange, this tube bank has two stiff ends and a unsteady quality end.Chinese invention patent " spatially spiral elasticity-intensified heat exchange tube bundle and bracing or strutting arrangement thereof " (application number: 200810015875.3) propose a kind of spatially spiral elasticity-intensified heat exchange tube bundle, tube bank is divided into single-screw type and double helical form, and unsteady mass is arranged on the double helical form heat exchanger tube.The operation principle of foregoing invention is the horizontal heat-exchanging tube bundle that skims over of shell-side fluid, utilizes the different flowing velocities of different fluid medium and fluid, induces heat transfer element to realize needed vibration, realizes the designing requirement of the different vibration shapes to satisfy heat-exchanging tube bundle.Unsteady mass is the critical piece of flow-induced heat exchanger tube vibration, is the pith that influences the heat-exchanging tube bundle vibration shape, frequency and amplitude.
The shortcoming of said structure is at first after the heat exchanger manufacturing installs, and heat-exchanging tube bundle is definite fully, and housing inner fluid medium and flow velocity become the principal element that influences the heat-exchanging tube bundle vibration shape, frequency and amplitude.Be difficult to by medium and the desired vibration shape of flow velocity acquisition heat-exchanging tube bundle, frequency and the amplitude that changes the housing inner fluid.Secondly after the heat exchanger manufacturing installed, if fluid media (medium) or flow velocity change, then a kind of situation may be less because of the frequency and the amplitude of the vibration of flow-induced heat-exchanging tube bundle, do not have very good heat exchange effect; Another situation may be bigger because of the frequency and the amplitude of the vibration of flow-induced heat-exchanging tube bundle, and heat-exchanging tube bundle can very fast generation fatigue rupture.So how obtaining the desired vibration shape of heat-exchanging tube bundle, frequency and amplitude comparatively accurately and conveniently is one of difficult point problem of strengthening heat exchange of elastic tube bundle heat exchanger.
Goal of the invention
The purpose of this utility model is exactly in order to address the above problem, provide a kind of elastic tube bundle heat exchanger to flow vibration inducing device with pulsation, it can obtain the desired vibration shape of heat-exchanging tube bundle, frequency and amplitude, reaches and both improves heat exchange efficiency, avoids the heat-exchanging tube bundle fatigue rupture again.
For achieving the above object, the utility model adopts following technical scheme:
A kind of elastic tube bundle heat exchanger flows vibration inducing device with pulsation, and it comprises pulsation stream pipe, flows on the pipe in pulsation to be provided with several delivery ports, in the end of pulsation stream pipe pulsating flow generator is installed.
A kind of elastic tube bundle heat exchanger flows vibration inducing device with pulsation, and it comprises pulsation stream pipe, flows on the pipe in pulsation to be provided with several delivery ports, and pulsating flow generator is installed on delivery port.
Described pulsation stream Guan Yiduan is fixed on the low head, and an end suspends and is connected with pipeline valve.
Be provided with delivery port in the utility model on pulsation stream pipe, pulsating flow generator is installed in pulsation and flows tube end, and pulsation stream Guan Yiduan is fixed on the low head, and an end suspends, and pulsating fluid is flowed out by delivery port, impacts the unsteady mass of corresponding elastic tube bundle.
The beneficial effects of the utility model are: the fluid flow and the flow velocity that enter pulsation stream pipe by control, select suitable pulsating flow generator for use at pulsation stream tube end, thereby the fluid driving frequency and the intensity at control pulsation stream pipe delivery port place, make the elastic tube bundle vibration shape, frequency and amplitude vibration as requested, reach the flow-induced heat exchange effect that both improves the elastic tube bundle heat exchanger, avoid the purpose of elastic tube bundle heat exchanger fatigue rupture again.The utility model all can be used plane elasticity tube bank and spatial elastic tube bank.
