Abstract
The utility model discloses a heat exchanger, in particular a shell-and-tube heat exchanger, and provides the shell-and-tube heat exchanger with slantwise arranged heat exchange tubes. The heat exchanger comprises a circular tube-shaped shell and is characterized in that: cooling water openings are respectively formed at the two ends of the upper side and the lower side of the shell; cooling water channels, which are composed of tube plates and heat exchange tubes communicated with the tube plates, are arranged among the cooling water openings; an axis of a main body portion of the heat exchange tube and an axis of the shell form an included angle; loose steel tube flanges with welding neck collars that are directly connected with the pipeline are arranged at the two ends of the shell. The heat exchanger has the advantages that: the heat exchanger can be directly added into a large fluid pipeline to help fluid accomplish a condensation effect during a flow progress; with use of threaded heat exchange tubes, a contact area of fluid with cooling water is increased; besides, the heat exchange tubes are slantwise installed, compared with vertically installed heat exchange tubes, the length of the heat exchange tubes is greatly increased, a heat exchange area is increased, heat exchange effect is enhanced, and a utilization rate of cooling water is improved; moreover, the heat exchange tubes are convenient in assembly and disassembly, and therefore are beneficial for maintenance of the pipeline as well as washing of the heat exchanger.
Description
Technical field
The utility model discloses a kind of heat exchanger, the shell-and-tube heat exchanger that particularly a kind of heat exchanger tube is obliquely installed.
Background technology
The most common heat exchanger, is generally plate type heat exchanger and shell-and-tube heat exchanger at present.Shell-and-tube heat exchanger claims again tubular heat exchanger, and housing mostly is cylindrical shape, and tube bank is equipped with in inside, and tube bank two ends are fixed on the tube sheet at cylindrical shell two ends, parallel with cylindrical shell.It is inhomogeneous smooth and easy that this structure causes cold fluid to flow in pipe, and the structure of end socket and bobbin carriage is also more complicated, causes not easy cleaning of heat exchanger.Installation environment is required high, and can change the flow direction and the speed of original fluid, large flow rate working conditions is not suitable for.
Summary of the invention
For the deficiency of existing conventional tube shell heat exchanger, the shell-and-tube heat exchanger that the utility model provides a kind of heat exchanger tube to be obliquely installed.This heat exchanger is feature in heat exchanger tube arranged, has improved the utilization rate of cooling water, has improved heat exchange efficiency, and is applicable to special operation condition, and installation and maintenance is also very convenient.
The technical scheme in the invention for solving the technical problem is: form refrigerant passage by tube sheet and heat exchanger tube, the import and export of cooling water lay respectively at the upper and lower both sides of housing, and the axis of heat exchanger tube and the axis of cylindrical shell are an angle; Housing is directly crossed welding neck collar pine cover steel pipe flanges with device for cleaning pipeline and is connected.
Described heat exchanger tube is stainless steel heat exchange tube, and material is 316L stainless steel, and heat exchange tube structure is screwed pipe.
Heat exchanger tube and housing are not parallel, and are 5 ° of-30 ° of angles.
There is technique bending described heat exchanger tube and tube sheet junction.
Described housing two ends do not have end enclosure structure, directly cross Flange with device for cleaning pipeline and are connected.
In sum, the shell-and-tube heat exchanger that a kind of heat exchanger tube is obliquely installed, comprises and the housing of circular tube shaped it is characterized in that cooling nozzle is separately positioned on the two ends of the upper and lower side of housing; Between cooling nozzle, form cooling-water duct by the heat exchanger tube of tube sheet and connection tube sheet, the axis of heat exchanger tube main part and the axis of housing are an angle; Housing two ends arrange the welding neck collar pine cover steel pipe flanges being directly connected with pipeline.
Described heat exchanger tube is stainless steel heat exchange tube, and material is 316L stainless steel, and heat exchange tube structure is screwed pipe.
Heat exchanger tube and housing are not parallel, and are 5 ° of-30 ° of angles.
There is technique bending described heat exchanger tube and tube sheet junction.
This heat exchanger advantage is can directly join in large fluid line, make fluid in flow process, complete cooling effect, thread heat exchange pipe has increased fluid and cooling water contact area, and because heat exchanger tube is for tilting to install, with respect to vertical installation, the large leap ahead of heat exchanger tube length, heat exchange area increases, heat transfer effect improves, and cooling water utilization rate improves.Do not affect the flow velocity of original fluid, easy to use.Be equivalent to add a segment pipe in original pipeline, in the time of this pipeline of fluid process, completed heat exchange.And easy accessibility, is conducive to pipeline maintenance and heat exchanger and cleans.
