Fig. 2 is the cross-sectional view of the shell-and-tube heat exchanger being provided with liquid spray thrower of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, so that clearer understanding objects, features and advantages of the present invention.It should be understood that embodiment shown in the drawings is not limitation of the scope of the invention, and the connotation just in order to technical solution of the present invention is described.
Fig. 1 illustrates the liquid spray thrower 10 for shell-and-tube phase change heat exchanger according to one embodiment of the invention.Fig. 2 illustrates the cross-sectional view of the shell-and-tube heat exchanger being provided with liquid spray thrower 10 of the present invention.As illustrated in fig. 1 and 2, shell-and-tube phase change heat exchanger 20 comprises housing 21 and heat exchanger tube 22, is provided with liquid spray thrower 10 inside housing 21, and liquid spray thrower 10 is placed in above heat exchanger tube 22.
Liquid spray thrower 10 comprises: inlet tube 1, collecting pipe 2, many medium pipelines 3 and the multiple shower nozzles 4 be positioned on medium pipeline 3.Inlet tube 1, collecting pipe 2 and medium pipeline 3 mutually fluid are communicated with, thus heat transferring medium can enter collecting pipe 2 by inlet tube 1, and enter medium pipeline 3 via collecting pipe, finally ooze from the multiple shower nozzles 4 medium pipeline 3 or spray.
Collecting pipe and many medium pipelines are arranged in and match with the inner wall shape of shell-and-tube heat exchanger 20, and as shown in Figure 2, thus shell-and-tube heat exchanger 20 can hold more heat exchanger tube 21.Particularly, in the embodiment shown in Figure 2, the housing section shape of shell-and-tube heat exchanger 20 is circular, correspondingly, collecting pipe 2 is curved, and medium pipeline 3 is also arranged in arc, thus make the inner surface of liquid spray thrower 10 as far as possible laminating shell-and-tube heat exchanger 20, save space.
Particularly, in the embodiment shown in Fig. 2, inlet tube 1 is a three-way pipe.Its mouth of pipe be interconnected with three, wherein two mouths of pipe are connected with collecting pipe 2, another mouth of pipe and heat transferring medium fluid communication.One as the present embodiment is out of shape, and inlet tube 1 also can be two siphunculus, and an one mouth of pipe is communicated with collecting pipe 2 fluid, another mouth of pipe and heat transferring medium fluid communication.The inlet tube of other form also can be suitable for, and describes in detail no longer one by one as space is limited at this.
Collecting pipe 2 is the pipe of an arc-shaped bend, and its cross section is quadrangle, and its both sides connect multiple medium pipeline 3, thus this collecting pipe 2 is communicated with medium pipeline 3 fluid.Other forms of collecting pipe, such as cross section is circular, as long as this collecting pipe is convexly curved, also goes for the present invention.
Preferably, collecting pipe 2 and medium pipeline 3 can be made up of materials such as carbon steel, low-alloy steel, stainless steel, copper, corronil, aluminium alloy, titaniums.Can be made up of some nonmetallic materials in addition, as graphite, pottery, polytetrafluoroethylene (PTFE) etc.
Medium pipeline 3 is made up of many elongated tubulars.These pipe one end are connected to collecting pipe 2 side, and one end seals.The tube wall of this medium pipeline 3 connects multiple shower nozzle 4, medium pipeline 3 is communicated with shower nozzle 4 fluid, thus heat transferring medium can spray from shower nozzle 4 or ooze.
Heat transferring medium is entered by inlet tube 1 and flows to each medium pipeline 3 through collecting pipe 2, then flows out this liquid spray thrower from the shower nozzle each medium pipeline 3.
Heat transferring medium can be any known suitable medium in this area, and such as conventional phase-change heat-exchange material water or oil also can be inorganic PCM, organic PCM and compound PCM.Wherein, mineral-type PCM mainly contains crystalline hydrate salt, molten salts, metal or alloy class etc.; Organic PCM mainly comprises paraffin, acetic acid and other organic matters.
Because collecting pipe 2 is convexly curved, cause the medium pipeline also curved arrangement be on the whole communicated with this return duct 2 fluid.Thus whole liquid spray thrower is an arcuate structure.
Owing to have employed the distribution of this arc, when liquid spray thrower of the present invention is installed in shell-and-tube phase change heat exchanger, this liquid spray thrower distributes along the housing of shell-and-tube phase change heat exchanger, thus saved space, add the heat exchanger tube quantity that this heat exchanger can hold, the heat exchanger tube filling rate of heat exchanger significantly improves.
As shown in Figure 2, after having installed liquid spray thrower of the present invention, the shell-and-tube phase change heat exchanger of unit volume can fill more heat exchanger tube, and the heat exchanger tube filling rate of heat exchanger significantly improves, compare existing shell-and-tube phase change heat exchanger, filling rate improves 25-55%.Meanwhile, due under the condition of same volume, the quantity of heat exchanger tube increases, and thus, heat exchange efficiency improves, and compared to existing shell-and-tube heat exchanger, heat exchange efficiency improves 15-25%.
Above-mentionedly by reference to the accompanying drawings embodiments of the present invention to be explained in detail, but the present invention is not limited to above-mentioned embodiment.Even if should be understood that and make various change to the present invention, as long as described those skilled in the art do not need creative work and available equivalent implementations, all fall among protection scope of the present invention.
