Solid production systems, devices, and methods utilizing oleophilic surfaces
Solid production systems, devices, and methods utilizing oleophilic surfaces are provided in accordance with various embodiments. Some embodiments include a water tank used to store fresh water. Some embodiments include an emulsion tank that may include a set of auxiliary components that may be utilized to create and/or to pump an emulsion. This auxiliary equipment may include suction headers, ejectors, pumps, mechanical mixers, and/or hydrodynamic mixers, for example. Some embodiments include a heat exchanger that may produce a cold surface for ice formation. This surface may include an oleophilic surface that may produce an affinity for oils and/or other non-polar materials. Some embodiments include piping that may allow for the connection of the other components such that ice may be formed from a flow of water from the emulsion and the overflow may be returned to the emulsion tank. Ice making methods are also provided.
1. An ice making system comprising;
an emulsion tank;
a heat exchanger that includes an oleophilic surface; and
a pump that pumps a liquid emulsion from the emulsion tank to the oleophilic surface of the heat exchanger such that the liquid emulsion flows down the oleophilic surface of the heat exchanger to form an oil layer on the oleophilic surface of the heat exchanger and to form an ice sheet on the oleophilic surface of the heat exchanger with the oil layer between the ice sheet and the oleophilic surface of the heat exchanger, wherein:
the pump curtails pumping of the liquid emulsion to the oleophilic surface of the heat exchanger with the ice sheet formed on the oleophilic surface of the heat exchanger with the oil layer between the ice sheet and the oleophilic surface of the heat exchanger; and
the heat exchanger subcools the ice sheet formed on the oleophilic surface of the heat exchanger with the oil layer between the ice sheet and the oleophilic surface of the heat exchanger and with the pump curtailed from pumping the liquid emulsion to the oleophilic surface of the heat exchanger.
2. The ice making system of claim 1 , further comprising a water tank coupled with the emulsion tank to provide water to the emulsion tank.
3. The ice making system of claim 1 , further comprising a suction port positioned with respect to the emulsion tank and the pump to remove water and oil from the emulsion tank to form the liquid emulsion pumped to the oleophilic surface of the heat exchanger.
4. The ice making system of claim 1 , further comprising an ejector positioned with respect to the emulsion tank and the pump to mix water and oil from the emulsion tank to form the liquid emulsion pumped to the oleophilic surface of the heat exchanger.
5. The ice making system of claim 1 , further comprising a mixer positioned with respect to the emulsion tank and the pump to mix water and oil from the emulsion tank to form the liquid emulsion pumped to the oleophilic surface of the heat exchanger.
6. The ice making system of claim 1 , further comprising the liquid emulsion, wherein the liquid emulsion includes water and oil.
7. The ice making system of claim 1 , wherein the oleophilic surface of the heat exchanger is vertically oriented such that the liquid emulsion flows down the oleophilic surface of the heat exchanger.
8. The ice making system of claim 1 , wherein the oleophilic surface of the heat exchanger includes at least PTFE, FEP, Polyethylene, Nylon, Acetal, PVDF, Silicone, or an oleophilic plastic.
9. The ice making system of claim 1 , wherein the oil includes at least a hydrocarbon oil, a fluorocarbon oil, or a silicone oil.
