Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a high temperature heat exchanger according to the present invention, and fig. 2 is an enlarged view of a position a of fig. 1. As shown in fig. 1 and 2, the utility model discloses a high-temperature heat exchanger, including casing 1, tube bank 2, first fixed head 3, first end plate 6, second end plate 7, second fixed head 4 and activity head 5. The first fixed seal head 3 is welded with the shell 1 in a sealing manner, the first end plate 6 is fixed at one end, close to the first fixed seal head 3, of the shell 1 in a sealing manner, one end of the outer wall of the tube bundle 2 is welded with the first end plate 6 in a sealing manner, the other end of the outer wall of the tube bundle 2 is fixed with the second end plate 7 in a sealing manner, the second end plate 7 is fixed with the movable seal head 5 in a sealing manner, the second fixed seal head 4 is arranged outside the movable seal head 5, and a gap is reserved between the movable seal head 5 and the second fixed seal head 4; the second fixed seal head 4 is fixed with the shell 1 in a sealing mode.
The working principle is as follows:
the utility model discloses a when high temperature heat exchanger carries out the heat exchange, the heat medium gets into from tube side entry 8 the utility model discloses an among the high temperature heat exchanger, in 6 departments of first end plate from near first fixed head 3 got into the tube bank, carry out the heat exchange with the liquid in the shell side in the casing 1, from 7 departments of second end plate flows, and the 9 departments of managing of the journey of 5 departments of activity head after turning back flow out. In the process, because the temperature of the liquid in the shell pass at one side of the shell 1 is generally higher, and the temperature of the heating medium in the tube pass is lower, at the moment, the thermal expansion degrees of the tube bundle 2 and the shell 1 are different, the expansion and contraction of the tube bundle 2 and the second end plate 7 fixed with the tube bundle 2 are expanded and contracted towards the second fixed seal head 4 through the movable seal head 5 together and are not limited by the shell 1, and therefore the tearing among the end plates, the tube bundle and the shell caused by the different expansion degrees can not occur.
Preferably, the gap between the movable seal head 5 and the first fixed seal head 4 is more than 8 cm. And a proper gap of 8cm can be kept to ensure that the movable seal head 5 has enough telescopic space.
Preferably, a partition plate 10 is arranged in the high-temperature heat exchanger, the partition plate 10 divides the shell side in the shell 1 into two parts, one part is connected with the tube side inlet 8, the other part is connected with the tube side outlet 9, and the two parts are communicated with each other at the movable end sealing end. The separation by the partition plate 10 avoids the mixing of inlet and outlet liquids in the shell side, increases the heat exchange path and leads the heat exchange efficiency to be higher.
It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the respective technical features described above may be combined with each other as long as they do not conflict with each other.
