现有利用发动机烟气余热为热源的表面式海水淡化器，通常以光滑管作为海水与烟气的传热界面，这种技术存在几项主要缺点：(一)光滑管的传热性能差，传热温差大，对低温余热的利用效果差，不利于采用多效蒸发；(二)光滑管容易在连接处产生泄漏，一旦管子泄漏，海水流入烟道，将对发动机产生严重的影响，使用安全性较差；(三)光滑管海水蒸发段水的过热度较大(12～15℃)，容易积垢，从而影响传热管的换热性能。Existing surface-type seawater desalinators that use exhaust heat from engine flue gas as a heat source usually use smooth tubes as the heat transfer interface between seawater and flue gas. This technology has several major disadvantages: (1) The heat transfer performance of smooth tubes is poor, The heat transfer temperature difference is large, and the utilization effect of low-temperature waste heat is poor, which is not conducive to the use of multi-effect evaporation; (2) the smooth pipe is prone to leakage at the joint. Once the pipe leaks, seawater will flow into the flue, which will have a serious impact on the engine. Use The safety is poor; (3) The degree of superheat of the water in the seawater evaporation section of the smooth tube is relatively high (12-15°C), and it is easy to accumulate scale, thereby affecting the heat transfer performance of the heat transfer tube.

本发明的另一目的在于提供一种上述海水淡化器的传热强化方法。Another object of the present invention is to provide a method for enhancing heat transfer of the above-mentioned seawater desalination device.
本发明的目的通过下述技术方案实现：本复合型粗糙肋面高效热管海水淡化器包括烟气通道、换热管、冷凝管，换热管一部分位于烟气通道内，其余部分位于烟气通道外，其特征在于换热管位于烟气通道内及位于烟气通道外的部分分别加工有翅片。The object of the present invention is achieved through the following technical solutions: the composite rough-ribbed surface high-efficiency heat pipe seawater desalination device includes a flue gas channel, a heat exchange tube, and a condenser tube. A part of the heat exchange tube is located in the flue gas channel, and the rest is located in the flue gas channel. In addition, it is characterized in that the parts of the heat exchange tube located in the flue gas channel and the parts located outside the flue gas channel are respectively processed with fins.
所述位于烟气通道内的部分加工有周向非连续三维翅片。The part located in the flue gas channel is processed with circumferential discontinuous three-dimensional fins.
所述周向非连续三维翅片均匀分布在换热管位于烟气通道内部分的外表面，其形状为三棱锥或四棱锥。The circumferential non-continuous three-dimensional fins are evenly distributed on the outer surface of the part of the heat exchange tube located in the flue gas channel, and the fins are in the shape of a triangular pyramid or a quadrangular pyramid.
所述位于烟气通道外的部分加工有“T”形翅片。The part located outside the flue gas channel is processed with "T" shaped fins.
所述“T”形翅片加工有开孔及槽口，位于换热管外表面；在换热管外表面所有“T”形翅片的槽口沿周向环绕排列在一起形成长条状的微细隧道。The "T"-shaped fins are processed with holes and notches, which are located on the outer surface of the heat exchange tube; all the notches of the "T"-shaped fins on the outer surface of the heat exchange tube are arranged around the circumference to form a long strip tiny tunnels.
所述冷凝管外加工有翅片；所述翅片为周向非连续三维翅片，周向非连续三维翅片均匀分布在换热管位于烟气通道内部分的外表面，其形状为三棱锥或四棱锥。The condensing tube is processed with fins; the fins are non-continuous three-dimensional fins in the circumferential direction, and the non-continuous three-dimensional fins in the circumferential direction are evenly distributed on the outer surface of the part of the heat exchange tube located in the flue gas channel, and the shape is a triangular pyramid or a quadrangular pyramid .
本海水淡化器还包括有汽-水分离隔板、集液槽，汽-水分离隔板设置在冷凝管下，汽-水分离隔板的下侧安装有集液槽。The seawater desalinator also includes a steam-water separation baffle and a liquid collection tank. The steam-water separation baffle is arranged under the condensation pipe, and a liquid collection tank is installed on the lower side of the steam-water separation baffle.
本复合型粗糙肋面高效热管海水淡化器的传热强化方法为：在位于烟气通道内的换热管外表面加工翅片以促进换热管外界面形成湍流，提高对流传热膜系数；同时在位于烟气通道外的换热管外表面加工翅片形成周向“T”形微细隧道肋面结构使海水在微细隧道中形成高速膜状蒸发，大幅提高汽泡的发射频率，增大沸腾传热膜系数。The heat transfer enhancement method of the composite rough-ribbed high-efficiency heat pipe seawater desalination device is as follows: fins are processed on the outer surface of the heat exchange tube located in the flue gas channel to promote the formation of turbulent flow at the outer interface of the heat exchange tube and increase the convective heat transfer film coefficient; At the same time, fins are processed on the outer surface of the heat exchange tube located outside the flue gas channel to form a circumferential "T"-shaped micro-tunnel rib structure, so that seawater can form a high-speed film evaporation in the micro-tunnel, which greatly increases the emission frequency of bubbles and increases Boiling heat transfer film coefficient.

本发明与现有技术相比具有如下的优点：Compared with the prior art, the present invention has the following advantages:
(1)本复合型粗糙肋面高效热管海水淡化器位于烟气通道内的对流段换热管表面加工的周向非连续三维翅片使其对流传热膜系数比光滑传热管高2～3倍；位于烟气通道外的蒸发段换热管表面加工的“T”形翅片管使海水沸腾的过热度比光滑传热管小2～3倍；蒸汽冷凝采用周向非连续三维翅片冷凝管，冷凝传热膜系数比光滑管传热管高3～5倍；由于三个传热过程均采用了良好的传热强化工艺，故本海水淡化器的传热效率高、所需的传热面积小，因而结构非常紧凑、体积较小，在船上使用尤为便利，设备生产成本比使用光滑传热管的海水淡化器下降，经济效益较好。(1) The circumferential non-continuous three-dimensional fins processed on the surface of the heat exchange tube in the convection section of the composite rough rib surface high-efficiency heat pipe desalination device make the convective heat transfer film coefficient 2 to 3 times higher than that of the smooth heat transfer tube ;The "T" shaped finned tube processed on the surface of the heat exchange tube in the evaporation section outside the flue gas channel makes the superheat of seawater boiling 2 to 3 times smaller than that of a smooth heat transfer tube; steam condensation adopts circumferential discontinuous three-dimensional finned condenser tube, The condensing heat transfer film coefficient is 3 to 5 times higher than that of the smooth tube heat transfer tube; because the three heat transfer processes all adopt a good heat transfer enhancement process, the heat transfer efficiency of the seawater desalinator is high, and the required heat transfer area Small, so the structure is very compact, the volume is small, and it is especially convenient to use on board. The production cost of equipment is lower than that of seawater desalinators using smooth heat transfer tubes, and the economic benefits are better.
(2)由于本海水淡化器各换热段的传热性能好，所需传热温差小，故有利于利用多效蒸发，提高海水淡化器的生产能力。(2) Since the heat transfer performance of each heat exchange section of the seawater desalinator is good, the required heat transfer temperature difference is small, so it is beneficial to use multi-effect evaporation to improve the production capacity of the seawater desalinator.
(3)由于本海水淡化器的海水蒸发段采用“T”形翅片管使海水沸腾的过热度较小，且汽泡发射的频率又很高，故可有效减缓管表面积垢的速度，延长海水淡化器清洗污垢的周期，降低设备维护成本。(3) Since the seawater evaporation section of this seawater desalinator adopts "T" shaped finned tubes to make the superheat of seawater boiling small, and the frequency of bubble emission is high, it can effectively slow down the speed of fouling on the surface of the tubes and prolong the life of the seawater. The desalination machine cleans the dirt cycle, reducing equipment maintenance costs.
