DEVICE FOR ONSITE SULPHUR MELTING Russian patent published in 2009 - IPC C01B17/02 B01J6/00 

FIELD: mechanics; heating.

SUBSTANCE: heater element comprises a set of spacing-separated melting tubes that form a heating plane, the upper collector tube and the lower collector tube attached to the relevant ends of the melting tubes and communicating with them. The upper collector tube has an inlet for steam delivery and distribution within the melting tubes system. The lower collector tube has an outlet for condensate collection and discharge. In addition the heater element is equipped with a hot-tipped tube positioned beside and before the lower collector tube. The hot-tipped tube has a steam inlet and a condensate outlet and is intended for sulphur melting before the lower collector. The heater elements may be controllable and modular. The device for solid sulphur melting consists of a support tower for the heater element transportation, a fixture for at least partial support of the heater element in the vertical position, a fixture for the heater element transfer from the vertical position to a basically horizontal one on a transportation truck, a fixture for the melting device travel across the ground surface in the direction of solid sulphur storage location. The latter fixture comprises a hydraulic cylinder, a directional distributing valve and a variable volume pressure compensation pump. The heater element for melting cross band contaminated sulphur consists of a set of spacing-separated melting tubes confining the melting plane and individual melting tubes having steam inlets and condensate outlets with the specified set of melting tubes performing cross band contaminated sulphur melting whenever the device comes in contact with a bulk of sulphur containing a cross band.

EFFECT: simplified and relatively inexpensive fabrication technique; possibility of onsite sulphur melting.
