Our company produces semi pipe jacket typestainless steel reactorThe tank body consists of a lower head, a cylinder, and an upper head. The tank body is equipped with a lower manhole and an upper manhole for maintenance. The tank body also has process pipe openings for adding different raw materials, as well as mixing and discharging ports. A half pipe jacket capable of heating or cooling is fixed in a spiral shape on the outer walls of the cylinder body and the lower head. The cross-section of the half pipe jacket is an open semi-circular pipeline, and there is an inner groove with a missing corner on both sides of the inner side of the pipeline, which is fixed to the tank body by full penetration welding. At least two vertical baffles are uniformly distributed along the circumference on the inner side wall of the cylinder. This utility model processes the inner side of the half pipe jacket into a groove, which can be fully welded to the cylinder without any gap, effectively solving the problem of internal gap corrosion in the half pipe and extending the service life of the pipeline. And by adding spoilersstainless steelThe internal medium of the reaction vessel is uniformly heated (cooled), which improves the convective heat transfer coefficient and the heating (cooling) performance of the half tube jacket.

shouldstainless steelReaction vessels are used in petroleum, chemical, rubber, dye, pharmaceutical, and other industries to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation, especially a semi tube jacket type pressure vesselstainless steelreaction kettle. In fields such as petrochemicals, jacketstainless steelReaction vessels are very common equipment, with traditional jackets being U-shaped or cylindrical. To enhance heat transfer, a spiral guide plate is installed inside. However, due to the large area of the inner cylinder that needs to withstand the pressure of the medium inside the jacket, the calculated length of the outer pressure is long. To ensure strength, the wall thickness of the inner cylinder is increased, which increases the equipment manufacturing cost. To save materials and reduce costs, the jacket can also be designed as a half tube and welded onto the inner cylinder.

In the jacketstainless steelIn the reactor equipment, the heat exchange process between the jacket and the inner cylinder is the convective heat transfer of the medium inside the jacket+the thermal conductivity of the inner cylinder wall+the convective heat transfer of the medium inside the cylinder. For example, when the agitator stirs the inner cylinder, the flow of the medium on the inner surface of the cylinder wall directly affects the heat transfer effect.

In traditional half tube jacketstainless steelOn the basis of the reactor structure, a groove is machined on the inner side of the half tube, which changes the welding between the half tube and the cylinder from incomplete welding with gaps inside to full welding without gaps, effectively solving the problem of gap corrosion inside the half tube and extending the service life of the pipeline. By adding turbulence devices, the heating (cooling) of the medium inside the reaction vessel is evenly distributed, and the convective heat transfer coefficient between the medium and the inside of the cylinder is improved. Improved the heating (cooling) performance of the half tube jacket.
