Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0019] Such as figure 1 , figure 2 , image 3 , Figure 5 As shown, the anti-vibration mechanism of the U-shaped heat exchange tube bundle in the still-type evaporator, the described kettle-type evaporator 1 includes a shell-side cylinder 2, and a U-shaped heat-exchange tube bundle 3 is arranged inside the shell-side cylinder 2, and the U-shaped The heat exchange tube bundle includes an upper straight section tube bundle 31 and a lower straight section tube bundle 32, the upper straight section tube bundle 31 is located above the lower straight section tube bundle 32, and the upper straight section tube bundle 31 and the lower straight section tube bundle 32 pass through a U-shaped bend tube section bundle 33 connections. Baffles 4 are interspersed on the upper straight tube bundle 31 and the lower straight tube bundle 32 .

The invention discloses an anti-vibrating mechanism for a heat exchange tube bundle in a kettle type evaporator. A plurality of hoop anti-vibrating assemblies are arranged at intervals in a shell sidebarrel body, wherein each hoop anti-vibrating assembly comprises a circular-arc-shaped pressure plate which covers on the top of a baffle plate, the two ends of the circular-arc-shaped pressure plateare separately tensioned on the inner wall of the shell side barrel body, and a tension structure between each end of the circular-arc-shaped pressure plate and the shell side barrel body comprises aconnecting rod which is arranged tilting down, the lower end of the connecting rod is welded and fixed with a nut, the nut is fixedly connected on a stud through threads, the stud is blocked on a mounting bracket on the inner wall of the shell side barrel body, the upper end of the connecting rod is equipped with threads, and is arranged penetrating through a connecting hole of a supporting plate, the supporting plate is fixedly arranged on the end part of the circular-arc-shaped pressure plate, the upper end of the connecting rod is equipped with a locking nut, and the locking nut is tightened for tensioning the circular-arc-shaped pressure plate and the shell side barrel body. The anti-vibrating mechanism has the advantage of effectively improving inherent frequency of the U-shaped heatexchange tube bundle, so that very good anti-vibrating effect is achieved.
Description
technical field [0001] The invention relates to the technical field of kettle-type evaporators, in particular to an anti-vibration mechanism for U-shaped tube bundles in the kettle-type evaporator. Background technique [0002] The kettle evaporator usually includes: a shell-side cylinder body, and a U-shaped heat exchange tube bundle is arranged in the shell-side cylinder body. The U-shaped heat exchange tube bundle is used for heat exchange with the medium in the shell-side cylinder body. The U-shaped heat exchange tube bundle includes the upper The straight section tube bundle and the lower straight section tube bundle, the upper straight section tube bundle is located above the lower straight section tube bundle, the upper straight section tube bundle and the lower straight section tube bundle are connected by a U-shaped bend section tube bundle, the upper straight section tube bundle and the lower straight section tube bundle A baffle is provided at the upper interval, ...
