Description

Technical Field

[0001] The utility model relates to the technical field of vertical sulfur pumps, in particular to a vertical sulfur pump using steam for heat preservation. Background Art

[0002] The steam-insulated vertical sulfur pump adopts the design principle of a centrifugal pump, and pushes liquid sulfur to the outlet pipe through centrifugal force. Due to the high temperature characteristics of sulfur, the design of the pump needs to take into account the problems of thermal expansion and thermal stress. The main structure of this pump includes the pump body, impeller, pump cover, shaft and other components, and in order to prevent the crystallization of liquid sulfur, the connecting pipe and the liquid outlet pipe are equipped with steam insulation jackets. This design can ensure that the sulfur remains in liquid state during the transportation process, preventing blockage and damage to the equipment.

[0003] At present, in actual application, vertical sulfur pumps using steam insulation adopt the design principle of centrifugal pumps to push liquid sulfur to the outlet pipeline through centrifugal force. In order to prevent the liquid sulfur from condensing during transportation, a jacket is usually set to use steam for insulation. However, the steam in the jacket only heats the liquid sulfur inside the pump body pipeline, and cannot heat the liquid sulfur in the pipeline evenly, resulting in the local temperature of the liquid sulfur in the pipeline being too high or too low. If the temperature is too high, thermal expansion is likely to occur, affecting the transportation of sulfur. Utility Model Content
