In petroleum, chemical, light industry, pharmacy, energy and other industrial production, tubular graphite heat exchanger often needs to heat low temperature fluid or cool high temperature fluid to vaporize liquid into steam and condense it into liquid. All these processes need to be completed by heat exchanger. Graphite heat exchanger is widely used in industry due to its advantages of strong corrosion resistance, high thermal conductivity and high service temperature. In order to improve the heat exchange effect, the running speed outside the heat exchange tube is generally increased. At the same time, multiple flow selectors are often installed in the cylinder of the graphite heat exchanger at intervals, so that the flow direction of the fluid in the cylinder is S-shaped. However, this method increases the impact pressure on the baffle plate while increasing the fluid flow rate. The baffle plate often deforms, thereby damaging the heat exchange tube and bringing unnecessary economic losses. In view of this situation, most of the measures taken now are to increase the thickness of baffles, which increases the low cost weight of equipment and increases the cost input.

The baffle plate is provided with a stop, which is connected with the baffle plate and the shell in a collision way. The fluid resists the baffle plate, and the stop produces a force in the opposite direction to the baffle plate. The force can counteract part of the fluid resistance. The stop includes a sliding part and a fixed part. The sliding part can slide on the baffle plate through the connector, and is fixed on the fixed part between the shell and the baffle plate The expandable connector connected between the fixed part and the sliding part and the sliding part sliding on the baffle plate jointly play the role of supporting the baffle plate and enhancing the strength of the baffle plate, preventing the deformation of the baffle plate, reducing the cost input of the graphite heat exchanger, and extending the service life.
