Description
Technical Field
The utility model belongs to the technical field of the indirect heating equipment technique and specifically relates to a sintering waste heat recovery high-efficient heat exchanger.
Background
In power station boiler, kiln flue gas emission equipment, in order to reduce exhaust gas temperature, improve desulfurization, denitration, purification dust removal process efficiency, many adopt the heat exchanger of traditional straight type fluorescent tube structure, but the fluorescent tube arranges that the clearance is big heat exchange efficiency is low, and simultaneously flue gas composition is complicated, and flow field arranges the limitation and causes its deposition seriously, brings very big inconvenience for equipment maintenance clearance, simultaneously because the heat exchanger is huge, actual equipment cost and running cost are very big.
Disclosure of Invention
The utility model aims at the above circumstances, provide a high-efficient heat exchanger of sintering waste heat recovery, heat exchange tube deposition problem significantly reduces in this heat exchanger, and the clearance is convenient, and heat exchange efficiency improves, and heat exchanger compact structure moreover, and the running cost is lower relatively.
The utility model has the following concrete scheme: the utility model provides a sintering waste heat recovery high-efficient heat exchanger, has the casing frame, is equipped with square expander on the casing frame, is equipped with the tube bank of compriseing a plurality of heat exchange tubes in the square expander, and the both ends of tube bank are fixed with the casing frame through the tube sheet, be equipped with a plurality of headers on the both ends mouth of tube bank and collect the fluid that corresponds in the heat exchange tube, the header at both ends all communicates with external fluid source through business turn over house steward separately, the heat exchange tube is twist type pipe of twist, and the cross-section of arranging that all heat exchange tubes are constituteed adopts square, regular triangle or not equidistance staggered arrangement three's arbitrary one kind mode to.
Furthermore, in the utility model discloses in each row of heat exchange tube in the tube bank all carries out the interval through the hollow tube each other and fixes and settle inside housing frame.
Further, in the utility model discloses in the casing frame adopts angle steel and channel-section steel processing to make.
The utility model discloses after well cold, hot-fluid pass through the pipeline and get into the heat exchanger, the fluid all flows along the direction of heat transfer pipe wall distortion, has changed the flow direction of traditional intraductal direct current, the outside of tubes horizontal sweep heat exchange tube, very big improvement its heat exchange efficiency, simultaneously the utility model discloses heat exchange tube deposition problem significantly reduces in the heat exchanger, and it is more convenient to clear up, and heat exchange efficiency improves, and heat exchanger compact structure moreover, and the running cost is low.

FIG. 2 is a schematic view of the cut-away structure A-A in FIG. 1;
fig. 3 is an enlarged schematic view of the structure at K in fig. 1.
In the figure: the heat exchanger comprises a shell frame, a shell inlet and outlet header pipe, a hollow pipe, a heat exchange pipe, a square expansion pipe, a pipe plate and a collecting pipe, wherein the shell frame is 1, the inlet and outlet header pipe is 2, the hollow pipe is 3, the heat exchange pipe is 4, the square expansion pipe is 5, and the pipe plate is 6.
Detailed Description
Referring to fig. 1-3, the utility model relates to a high-efficient heat exchanger of sintering waste heat recovery has casing frame 1, and casing frame is last to be equipped with square expander 5, is equipped with the tube bank of constituteing by a plurality of heat exchange tubes 4 in the square expander, and the both ends of tube bank are passed through tube sheet 6 and are fixed with casing frame, be equipped with a plurality of collection pipes 7 on the both ends mouth of tube bank and to collect the fluid that corresponds in the heat exchange tube, the collection pipe at both ends all communicates with external fluid source through business turn over house steward 2 separately, the heat exchange tube is twist type pipe of twist, and the cross-section of arranging that all heat exchange tubes are constituteed adopts square, regular triangle or any one mode in the equidistance staggered.
Furthermore, in the present embodiment, the rows of heat exchange tubes in the tube bundle are fixed at intervals by the hollow tubes 3 and are arranged inside the shell frame.
Further, in this embodiment, the housing frame is formed by processing angle steel and channel steel.
In this embodiment, two end ports of the heat exchange tubes are respectively connected with a header, one end of the header is closed, the opening at the other end of the header is communicated with the corresponding inlet and outlet header, and then the headers are simultaneously communicated with the corresponding inlet and outlet header, so that uniform pipelines can be conveniently used for fluid inlet and outlet, and the pipelines are better arranged and controlled.
According to the different pipe diameters and the different twisting degrees of the heat exchange pipes with different specifications, the arrangement cross sections of all the heat exchange pipes can be arranged in any one of a square mode, a regular triangle mode and an unequal-distance staggered arrangement mode.
The heat exchange tube rows in the embodiment need to be prefabricated in advance, and then are fixedly arranged in the shell frame at intervals by hollow tubes.
When the heat exchanger of the utility model is used, high temperature flue gas flows forwards along the twisted direction of the pipe wall from the gap outside the heat exchange pipe, and liquid or gas to be absorbed absorbs heat from the circulation in the heat exchange pipe, and the heat exchange pipe adopts a twisted pipe in a twist shape, so that the heat absorption efficiency is greatly improved; meanwhile, as the pipe wall of the heat exchange pipe is a twist-shaped twisted pipe, through multiple related tests of fluidics, the accumulated dust on the outer wall of the heat exchange pipe is greatly reduced compared with that of a light pipe, so that the heat exchange pipe is greatly convenient to clean.
The utility model discloses after well cold, hot-fluid pass through the pipeline and get into the heat exchanger, the fluid all flows along the direction of heat transfer pipe wall distortion, has changed the flow direction of traditional intraductal direct current, the outside of tubes horizontal sweep heat exchange tube, very big improvement its heat exchange efficiency, simultaneously the utility model discloses heat exchange tube deposition problem significantly reduces in the heat exchanger, and it is more convenient to clear up, and heat exchange efficiency improves, and heat exchanger compact structure moreover, and the running cost is low.
