METHOD AND STEAM HEAT EXCHANGER ARRANGEMENT FOR THERMAL CONTROL OF THE CONTENT IN A VESSEL SPACE OF A VESSEL
Field of the invention
The invention relates to a method for thermal control of the content in a vessel space of a vessel such as a hydrometallurgical reactor as defined in the preamble of independent claim 1.
The invention also relates to a steam heat exchanger for thermal control of the content in a vessel space of a vessel such as a hydrometallurgical reactor as defined in the preamble of independent claim 8.
Publication US 8,443,870 presents a steam heat exchanger includes a steam heating pipe with a condensation pipe part and a sensible heat pipe part provided on the lower side of the condensation pipe part. In the condensation pipe part, a liquid is heated by latent heat. The drain discharge capacity in a steam trap or an orifice disposed on the drain discharge side equals the amount of condensation at the service temperature of the steam heat exchanger. Condensed water produced after the heat exchange in the condensation pipe part enters the sensible heat pipe part on the downstream side to hold the sensible heat pipe part in a water sealed state. In this sensible heat pipe part, the liquid is heated by sensible heat. Heat exchange efficiency is improved by using latent and sensible heat, the amount of steam used can be reduced, and the load of a steam generation source can be reduced.
Objective of the invention
The object of the invention is to provide an efficient method and steam heat exchanger for thermal control of the content in a vessel space of a vessel such as a hydrometallurgical reactor.
Short description of the invention
The method for thermal control of the content in a vessel space of a vessel such as a hydrometallurgical reactor of the invention is characterized by the definitions of independent claim 1.
Preferred embodiments of the method are defined in the dependent claims 2 to 7.
The steam heat exchanger for thermal control of the content in a vessel space of a vessel such as a hydrometallurgical reactor of the invention is correspondingly characterized by the definitions of independent claim 86.
Preferred embodiments of the steam heat exchanger are defined in the dependent claims 9 to 15.
In an embodiment the lower manifold is in fluid communication with the condensate pipe through a condensate well, which is arranged at a level below the lower manifold, and which is in fluid communication with the lower manifold for receiving condensate from the lower manifold. In this embodiment of the steam heat exchanger the lower manifold, the condensate pipe has an inlet opening that is horizontally arranged in the condensate well and that faced downwardly into the condensate well. This embodiment prevents effectively steam and condensate from simultaneously entering the condensate pipe through the inlet opening and reduces the hammering effect (also called “hydraulic shock”) inside the condensate pipe. A such embodiment also a positive effect on the phase change from steam to condensate and consequently a positive effect on the amount of thermal energy transferred from the steam. In this embodiment the condensate pipe has preferably, but not necessarily, a smaller inner cross-section than the inner cross-section of each of said vertically disposed heat transfer pipes. This has a positive effect on the ability to draw, for example to pump, condensate out of the steam heat exchanger arrangement regardless of the height of the vessel. This especially important if condensate is removed via an open top of a high vessel.
In an embodiment at least one of the upper manifold and the lower manifold comprises a plate means, which forms a part of an outer wall structure of the manifold that limits an inner manifold space and which is penetrated by the vertically disposed condensation heat transfer pipes. By forming a part of an outer wall structure of the manifold that limits an inner manifold space of such plate means, it is easier to provide a large number of heat transfer pipes between the upper manifold and the lower manifold. A large number of heat transfer pipes between the upper manifold and the lower manifold leads to a large heat exchanging area.
In an embodiment the steam heat exchanger arrangement comprises a rail structure for releasable suspending the steam heat exchanger arrangement in a vessel space of a vessel from a roof structure of the vessel. A such rail structure makes it unnecessary to fasten the steam heat exchanger arrangement to the walls of the vessel. The rail structure allows moving of parts of the steam heat exchanger arrangement with respect to the rail structure due to thermal expansion. The rail structure allows also removal of the steam heat exchanger arrangement from and inserting of the steam heat exchanger arrangement into the vessel space of the vessel without a need for compete emptying of all content from the vessel space of the vessel.
