Abstract
The application relates to a polymerization vessel and a method for manufacturing the same. An interior surface of the polymerization vessel has a specific structure, so that the polymerization vessel has better heat transfer efficiency. Closed cooling channels are constructed from the specific structure, and therefore cooling fluid flows in the closed cooling channels. Furthermore, there won't be any by-pass defects in the cooling channels of the polymerization vessel, thereby improving cooling efficiency of the cooling fluid.
Claims20
A polymerization vessel, comprising:
- a vessel body, including a vessel wall and a plurality of partition walls, and each of the partition walls protrudes from an interior surface of the vessel wall, wherein the partition walls and the vessel wall are integrally formed;
- at least one shell plate, jointing each adjacent two of the partition walls, wherein at least one flow channel is defined by each adjacent two of the partition walls, the vessel wall and the at least one shell plate;
- at least one fluid inlet, passing through the vessel wall, wherein the at least one fluid inlet communicates with the at least one flow channel in one-to-one manner;
- and
- at least one fluid outlet, passing through the vessel wall, wherein the at least one fluid outlet communicates with the at least one flow channel in one-to-one manner.
A method for manufacturing a polymerization vessel, comprising:
- performing an excavation process to an interior surface of a vessel body of the polymerization vessel to form at least one spiral flow channel, wherein each of the at least one spiral flow channel includes a plurality of grooves and a plurality of partition walls, and each one of the grooves is located between adjacent two of the partition walls;
- and
- respectively covering a shell plate on each of the grooves so as to subject each of the at least one spiral flow channel to be closed, wherein the shell plate is jointed to the adjacent two of the partition walls.
A method for manufacturing a polymerization vessel, comprising:
- performing an excavation process to an interior surface of a vessel body of the polymerization vessel to form at least one spiral flow channel, wherein each of the at least one spiral flow channel includes a plurality of grooves and a plurality of partition walls, and each one of the grooves is located between adjacent two of the partition walls;
- respectively covering a shell plate on each of the grooves so as to subject each of the at least one spiral flow channel to be closed, wherein the shell plate is jointed to the adjacent two of the partition walls to form an uniform inner surface of the polymerization vessel;
- and
- after covering the shell plate, performing an electroplating process to each of the at least one spiral flow channel so as to subject a surface of each of the at least one spiral flow channel to be equipped with a nickel layer.
