Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and in particular to a heat exchanger anti-collision baffle structure and a use method thereof. Background Art

[0002] Most of the current heat exchangers are equipped with anti-collision baffle structures, especially fixed tube sheet heat exchangers. Although their structure is simple and compact and can withstand higher pressures, if their tube bundles are subjected to local high temperatures so that their wall temperatures differ greatly from those of the shell, large thermal stresses will be generated in the tube bundles and the shell, which is detrimental to the heat exchanger tubes. However, there are also some cases where an anti-collision baffle structure is not necessary, such as when the fluid inlet flow rate is low or the fluid medium is non-corrosive. If an anti-collision baffle is installed, the heat exchange efficiency of the heat exchanger will be affected. Therefore, whether an anti-collision baffle is required at the shell side inlet of the heat exchanger must strictly comply with the standard of GB / T1512014 "Heat Exchanger". However, the existing technology has not yet considered the situation where an anti-collision baffle is not required when the heat exchanger is partially working. Therefore, the existing heat exchanger cannot simultaneously take into account the functions of anti-collision and no anti-collision. Summary of the Invention

[0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a heat exchanger anti-collision baffle structure and a method of using the same, wherein anti-collision baffle 1 can be moved away, and anti-collision baffle 2 remains to form a single anti-collision baffle, and the anti-collision baffle structure can be adjusted to use a single anti-collision baffle or a double anti-collision baffle; after anti-collision baffle 1 is moved away, when only anti-collision baffle 2 is left to form a single anti-collision baffle, anti-collision baffle 2 can be removed to form a function without anti-collision, and can be adjusted to anti-collision or no anti-collision, and there is a buffer structure between anti-collision baffle 2 and the fixed frame, and between anti-collision baffle 2 and the support frame, which forms a double buffer for anti-collision baffle 2 and reduces the impact force when anti-collision baffle 2 descends.

The design of double anti-collision baffles can enhance the structural strength of the system and prevent the baffle from shifting or being damaged under the impact of high-flow fluid.

[0006] According to a heat exchanger anti-collision baffle structure provided by the present invention, the upper end of the spring one is fixedly connected to the abutment pad one, and the lower end of the spring one is fixedly connected to the support frame. The elastic characteristics of the spring one can absorb the instantaneous pressure changes caused by the descent of the anti-collision baffle two, thereby reducing the impact on the support frame and other structures.

[0007] According to a heat exchanger anti-collision baffle structure provided by the present invention, the upper end of the second spring is fixedly connected to the second fixed block, and the lower end of the second spring is fixedly connected to the first abutment pad.

[0013] S1. When in use, the worm is rotated by the handle, so that the worm wheel meshing with the worm can rotate with the screw. The rotation of the screw enables the anti-collision baffle 1 connected to the screw thread to move. After the anti-collision baffle 1 moves away, the remaining anti-collision baffle 2 forms a single anti-collision baffle. The anti-collision baffle structure can be adjusted to use a single anti-collision baffle or a double anti-collision baffle;

[0014] S2, by extending the telescopic rod on the fixed block 1, the anti-collision baffle 2 connected to the telescopic rod can be moved, so that the anti-collision function can be formed without anti-collision, and it can be adjusted to anti-collision or no anti-collision;
