Abstract

The invention discloses a fixing method for preventing a coil pipe from being torn by stress. The method comprises the steps as follows: (1) an upper fixed station assembly is arranged on the inner wall of a reaction kettle and an upper accommodating tank is arranged in the upper fixed station assembly; (2) a lower fixed station assembly corresponding to the upper fixed station assembly is arranged on the inner wall of the reaction kettle and a lower accommodating tank is arranged; and (3) a coil pipe assembly is fixed on a support frame, an upper support plate and a lower support plate are arranged at the upper end and the lower end of the support frame respectively, and the upper support plate and the lower support plate are arranged in the upper accommodating tank and the lower accommodating tank respectively. According to the fixing method and a fixing structure for preventing the coil pipe from being torn by the stress, radial stress and axial stress of the coil pipe and a fixed end can be eliminated, the fixing method and the fixing structure are suitable for a medium with a large temperature difference, meanwhile, bolt fixing is adopted as the fixing mode of the support frame, installation and removal are convenient, fire operation in a small space is avoided and the operation security coefficient is improved.

Description

technical field [0001] The present invention relates to chemical equipment, especially designed reaction kettle. Specifically, it shows a fixing method for preventing stress tearing coils, and at the same time, it also shows a fixing method for preventing stress tearing coils based on a fixing method for preventing stress tearing coils structure. Background technique [0002] The heating or cooling of the reaction kettle adopts the coil heat exchanger, which is an indispensable heat exchange equipment for the esterification process. It is widely used because of its simple structure, easy manufacture, easy maintenance, and suitability for various materials. [0003] In the reactor currently used, a support channel steel is set in it to support the snake pipe, and the support channel steel is directly welded and fixed on the corresponding upper and lower fixed platforms in the reactor, which has the following defects: [0004] 1) Since the supporting channel steel is welded a...
