Heat transfer baffle system and uses thereof
This disclosure describes an improved heat transfer system for use in reaction vessels used in chemical and biological processes. In one embodiment, a heat transfer baffle comprising two sub-assemblies adjoined to one another is provided.
1. A heat transfer baffle comprising:
a. a first sub-assembly consisting essentially of a first material adjoined to a second material to form first distribution channel,
b. a second sub-assembly consisting essentially of a first material adjoined to a second material to form a second distribution channel,
c. a closure bar that adjoins the first assembly and the second sub-assembly to one another; and
d. a relief channel between the first sub-assembly and the second sub-assembly;
wherein:
the closure bar sets the width of the relief channel, and
the distribution channels and the relief channel do not communicate unless a leak forms within a distribution channel.
2. The heat transfer baffle of claim 1 comprising two or more distinct compartments through which heat transfer media may be circulated independently of any other compartment.
3. A heat transfer system comprising one or more heat transfer baffles of claim 1 adjoined to a reactor vessel.
4. The heat transfer system of claim 3 wherein the one or more heat transfer baffles are adjoined to the reactor vessel through a substantially seamless joint boundary between the baffle and the vessel.
5. A heat transfer system comprising one or more heat transfer baffles of claim 1 , wherein at least one distribution channel is adjoined to a heat transfer media inlet header.
6. A heat transfer system comprising one or more heat transfer baffles of claim 1 wherein at least one distribution channel is adjoined to a heat transfer media outlet header.
7. A heat transfer system comprising one or more heat transfer baffles of claim 1 , wherein at least one distribution channel is adjoined to a heat transfer media inlet header and a heat transfer media outlet header.
8. A heat transfer system comprising one or more heat transfer baffles of claim 1 adjoined to the interior surface of a reaction vessel, wherein each baffle is adjoined to at least one heat transfer media inlet header and at least one heat transfer media outlet header, and the relief channel of each baffle is vented to the vessel exterior.
9. The heat transfer system of claim 3 wherein the one or more heat transfer baffles are fixably attached to the interior surface of the reaction vessel such that when the vessel contains contents in motion resulting in stress upon the baffles, the stress is attenuated.
10. The heat transfer system of claim 9 wherein the one or more heat transfer baffles is fixable attached to the interior surface of the reaction vessel at an angle relative to the interior wall or radius of the vessel, the angle being selected from the group consisting of about 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, and 90°.
11. The heat transfer system of claim 10 wherein the angle is about 60° relative to the interior wall or about 30° relative to the radius.
12. A reaction vessel comprising within its interior at least one heat transfer baffle of claim 1 .
