[0002] In the production of anhydrous magnesium chloride particles, the removal of six crystal waters in magnesium chloride is a key process. The removal of the first four crystal waters can be achieved in an ordinary fluidized bed furnace, but the key is the removal of the last two crystal waters, which needs to be operated in an HCl gas environment. Therefore, in some hydrochloric acid analysis systems in dehydration workshops, the production of qualified HCl gas is the core process. Since the HCl gas has a high temperature and strong corrosiveness, most of the process equipment in this system is made of graphite material that is both temperature-resistant and corrosion-resistant. The graphite heat exchanger is the core static equipment in the hydrochloric acid analysis process system of the dehydration workshop. However, the graphite heat exchanger has a high failure rate during use and needs to be frequently disassembled and repaired. Since the overall equipment of the graphite heat exchanger is heavy, large in volume, and made of special materials.

[0003] Currently, for the hoisting and disassembly of the overall graphite heat exchanger equipment, cranes are usually used. However, during use, there are problems such as complex hoisting equipment, high cost, complex operation, and easy damage to graphite tubes.

An installation ring can be arranged on the first cross beam 122, and the hoisting member 2 can be detachably connected to the first cross beam 122 through the installation ring. The height of the first vertical column 121 is 12 m to 14 m, which is higher than the height of the graphite heat exchanger, and the length of the first cross beam 122 also needs to be greater than the width of the graphite heat exchanger.

[0026] When this application is in use, first adjust the hoist to adjust the height of the lifting member 2 to be the same as the height of the graphite heat exchanger. Connect the connecting ends of the lifting member 2 to both ends of the graphite heat exchanger. Lift the lifting member 2 to lift the entire graphite heat exchanger vertically and suspend it in the air. Then hang the lifting member 3 on the other end of the graphite heat exchanger. While pulling the lifting member 3, lower the height of the lifting member 2, where the pulling speed is adapted to the lowering speed, so as to horizontally place the graphite heat exchanger. During the whole process, it is not easy to cause collision damage to the graphite heat exchanger, etc. At the same time, the whole equipment has a simple structure, low cost and convenient operation. Among them, ears are symmetrically arranged on the outer walls of the upper half and the lower half of the graphite heat exchanger, which is convenient for lifting or disassembling. Since it is prior art, it will not be elaborated here.

[0027] Furthermore, a saddle can be provided below the horizontal frame body 11. During the process of horizontally placing the graphite heat exchanger, place the graphite heat exchanger on the saddle to further protect the graphite heat exchanger. The saddle is prior art and serves to accommodate and place the graphite heat exchanger in this application, so it will not be elaborated here.

[0028] Specifically, the horizontal frame body 11 includes second columns 111.
