Abstract: Embodiments of the invention are directed to a sulfur trap comprising an inlet, a first chamber, a divider, a second chamber, an outlet, and a float assembly. The float assembly may have many different configurations, but generally comprises a float and plug, is configured to float within liquid sulfur, and is operatively coupled to a seal seat in the divider for sealing and unsealing the first chamber from the second chamber. Generally, only liquid sulfur is allowed to pass from the first chamber into the second chamber. However, the sulfur trap may be configured to allow for pressure relief, such that during an overpressure event the plug and seal seat disengage and allow the liquid-gas mixture to flow into the second chamber to prevent damage within the system. In some embodiments a filter and/or the flow of liquid sulfur is directed to collect debris from the liquid sulfur.

Both valves are controllable in response to a fluid level in the gas/liquid phase separator. Both valves are further disposed in parallel fluid communication with each other.

Abstract: A separating tank assembly enables a dental vacuum separating tank to be drained without using a pump and without turning off or isolating the vacuum source from the tank. A drain tank is provided in fluid communication with the separating tank, and a control valve controls a pressure differential between the drain tank and the fluid tank. When the separating tank is filling, the drain tank and separating tank pressures are equalized, and the tanks are in fluid communication. When the fluid in the drain tank reaches a predetermined level, the solenoid opens the drain tank to atmosphere, blocking fluid communication between the separating tank and the drain tank and opening fluid communication between the drain tank and a sewer drain. After the fluid is drained, the solenoid reopens fluid communication between the separating tank and the drain tank, and the pressures in the respective tanks are equalized.

Abstract: A low flow rotary separator includes a housing that defines a separator chamber and a liquid/gas mixture inlet. A shaft driven by a motor includes a plurality of disks in frictional contact with the mixture to drive the liquid outward against an inner wall of the separator and displace gas to a central region about the shaft. The liquid exits through a liquid outlet valve into a high-pressure storage container. The pressure of the liquid is increased to allow flow into the high-pressure storage container by a pump driven by the shaft. A level control valve closes in response to a predetermined pressure differential between liquid in the feed line and liquid within the separator chamber to allow liquid flow through an outlet check valve.

The one-way valve is normally closed and can connect the outlet conduit with the outlet. The three-way valve and the one-way valve are brought into action when the fluid pressure in outlet from the separator reaches first and second predetermined values.

Abstract: Gas/liquid separating devices include a separator (1) for separating a mixed gas/liquid flow (M). A liquid drain (2) communicates with the separator and defines a liquid storage chamber (30).
