Description
Technical field：
The present invention is the novel heat exchange pipe for being capable of ant-scaling and augmentation of heat transfer, belongs to field of heat exchange equipment.
Background technology：
Heat exchanger tube is to be used for the critical elements of two medium heat exchanges in heat exchanger.In recent years, with the day of fossil energy
It is becoming tight, the utilization rate of the energy is increasingly valued by the people.Heat exchanger is used as its biography of widely used heat transmission equipment in industry
The performance of heat has very big influence to effective utilize of the energy.But, due to the fluid group for heat exchange or waste heat recovery
Into complicated component, dirt easily is produced on its inside pipe wall that exchanges heat in the heat transfer process of heat exchanger, heat exchange efficiency is influenceed, hinders
The proper flow of fluid, when serious, or even causes local corrosion or even perforation, triggers production accident.So, heat exchanger is prevented and kill off
Dirt and heat transfer enhancement technology increasingly obtain everybody research and concern.
Wherein, the anti-scale removal of ultrasonic wave and heat transfer enhancement technology are exactly a very effective technology.But, with people
The anti-scale removal of ultrasonic wave and augmentation of heat transfer are understood in depth, it is found that ultrasonic technology has that power consumption is big, operating distance is by sound source
The problems such as influenceing big.And the same Hydrodynamic Cavitation Technology based on acoustic cavitation principle then has its unique advantage.Hydrodynamic cavitation be by
Cavitation caused by the relative motion of solid in fluid and fluid.Hydrodynamic cavitation and the fundamental difference of ultrasonic cavitation are sky
Change the form difference that energy is provided.Hydrodynamic cavitation is more easy to realize compared with ultrasonic cavitation, and it is low to consume energy.
The present invention is based on Hydrodynamic cavitation principle, and the structure of traditional heat exchanger tube is transformed, using vertically-mounted mode,
Make heat exchanger in the process of running, long-acting anti-tartar, the effect of augmentation of heat transfer are reached by the appropriate adjustment of flow.
The content of the invention：
The present invention mainly overcomes traditional easy fouling of heat exchanger tube long-play, and heat exchange efficiency step-down, flow of fluid is obstructed
Problem.In the case where ensureing that heat transmission equipment is normally run, long-play non-scaling and augmentation of heat transfer are realized.
The long-acting heat exchanger tube of Pseudosasa japonica var. Tsutsumiana Yanagita Hydrodynamic cavitation ant-scaling of the present invention, by straight tube, changeover portion and Pseudosasa japonica var. Tsutsumiana Yanagita are changed
Heat pipe section composition.Upper and lower side, which is provided between straight tube and changeover portion, changeover portion, some Pseudosasa japonica var. Tsutsumiana Yanagita heat exchanger tube tube couplings, heat exchanger tube
By the way of placing vertically, fluid is flowed into by lower end.
The present invention flows through the change in section by fluid, cavitation bubble is constantly produced and is crumbled and fall, and reduces dirt particles and wall
The possibility of face adhesion, and produce disturbance so that heat exchange efficiency is improved.Wherein, in Pseudosasa japonica var. Tsutsumiana Yanagita heat exchanger tube tube coupling, bottom is expanded
Dissipate angle and be not less than 18 degree and no more than the 2/3 of top angle of throat, body is provided with the rounding that radius is 10 to 15, and body is maximum
Diameter is 3 with ratio at minimum diameter:1, so that bubble can be separated out, produce subsequent perturbations effect.
The present invention is different from traditional heat exchanger tube, introduces Hydrodynamic cavitation mechanism, by changing the structure of heat exchanger tube, makes simple
Single-phase flow be changed into biphase gas and liquid flow, so as to reach the effect of long-acting anti-tartar and augmentation of heat transfer.

8-straight tube
Embodiment：
The long-acting heat exchanger tube of Pseudosasa japonica var. Tsutsumiana Yanagita Hydrodynamic cavitation ant-scaling of the present invention uses vertical modes of emplacement, including fluid to pass through
Straight tube 1 enters lower transition section 2, and flow velocity accelerates, and pressure reduces, and then reaches Pseudosasa japonica var. Tsutsumiana Yanagita heat exchange tube coupling bottom 3, flows through peppery fragrant-flowered garlic
Bamboo heat exchange tube coupling bottom 4 is sweared, it is alveolate to disturb and crumble and fall so that dirt is difficult to adhere to internal face, and obtains the coefficient of heat transfer
Improve, then, sequentially pass through, 5 in the middle part of Pseudosasa japonica var. Tsutsumiana Yanagita heat exchange tube coupling, Pseudosasa japonica var. Tsutsumiana Yanagita heat exchange tube coupling top 6, disturbance is still present,
Most flowed out afterwards through top changeover portion 7 by straight tube 8.
