Abstract
The utility model is capable of improving the vibration of heat transfer pipes in case that the heat transfer pipes are in the triangular layout or in case that no direct channel is inserted into the anti-vibration rod between the heat transfer pipes. The technical scheme (see Figure 1) is that anti-vibration screw rods (1), the diameter of which is smaller than the gap between the heat transfer pipes (2) and the thread pitch of which is equal to the width between the centers of the heat transfer pipes, is inserted between the rows of the heat transfer pipes (2) through rotation, thus improving the vibration state of the heat transfer pipes.
Description
Technical field
The utility model relates to the shell-and-tube heat exchanger in the industry technological processes such as oil, chemical industry, generating, metallurgy.
Background technology
Tubular heat exchanger relies on the support of deflection plate to alleviate the vibration that medium impingement heat transfer pipe causes.Can not reduce again and heat exchanger tube when also needing further to shorten support distances when the deflection plate support distances is restricted, can insert straight vibrationproof bar in pipe row intermediate vertical and shorten the heat exchanger tube support distances.But arrange when the tube bank heat exchanger tube adopts rounded projections arranged, or, how to improve the bundle vibration state and become a difficult problem there not being beeline channel to insert under the straight vibrationproof bar situation between heat exchanger tube.
Summary of the invention
The utility model can solve at the tube bank heat exchanger tube and adopt rounded projections arranged to arrange, or there not being beeline channel to insert under the straight vibrationproof bar situation between heat exchanger tube, improves the bundle vibration state issues.Content of the present invention is that (see figure 1) is vibrationproof screw rod (1) rotation insertion in the middle of heat exchanger tube (2) the pipe row of needs support of heat exchanger tube centre-to-centre spacing less than heat exchanger tube (2) gap, pitch with diameter, reaches the purpose of improving the tube bundle vibration state.

The specific embodiment
The technical solution of the utility model is provided by following embodiment, after the tube bank assembling finishes, diameter is shaped into the vibrationproof screw rod that pitch is heat exchanger tube centre-to-centre spacing less than the round steel in heat exchanger tube gap by mold, the radius of spin can be decided according to the staggered size of heat exchanger tube, in the middle of the heat exchanger tube row that needs support the rotation of vibrationproof screw rod is inserted.Vibrationproof screw rod end after the insertion is welded on the steel bar, and the steel bar end is welded on the deflection plate.
Claims (1)
1, a kind of vibrationproof screw rod, heat exchanger tube adopt rounded projections arranged to arrange, it is characterized in that it is that the vibrationproof screw rod of heat exchanger tube centre-to-centre spacing is arranged in the middle of the heat exchange tube row that diameter is shaped into pitch less than the round steel in heat exchanger tube gap by mold.
