Abstract
Abstract An electronic system for automatically controlling the operation of a desalination system, and particularly such systems utilizing waste heat from internal combustion engines. The automatic control system is responsive to physical parameters within the desalinator and is particularly useful during warm-up and cooling periods at the beginning and end of use of such a desalination system for minimizing wear on system components and for maximizing the operational life of the system.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
A control system for operating a low pressure evaporative desalinator having a mechanism for introducing heat to a boiler chamber at temperatures below the atmospheric pressure boiling point of the raw water, a mechanism for drawing a vacuum within said boiler chamber, and a mechanism for pumping fresh water from said chamber, comprising: a main control switch having an ON position for activating and an OFF position for deactivating said desalinator; means for sensing the temperature of the raw water within said boiler chamber; means for sensing the vacuum within said boiler chamber; means responsively connected to said temperature sensing means and said switch for activating said vacuum drawing mechanism whenever said switch is in said ON position or said temperature sensing means monitors a temperature above a first predetermined level; means responsively connected to said switch and said vacuum sensing means for activating said heat introducing mechanism when said switch is in said ON position and said vacuum sensing means simultaneously monitors a pressure below a predetermined level which level is below atmospheric pressure; and means responsively connected to said switching means, said vacuum sensing means and said temperature sensing means for activating said fresh water pumping mechanism when said switch is in said ON position, when said temperature is simultaneously above a second predetermined level and when said pressure is simultaneously below said predetermined level.
Claim 2
Dependent Claim
227 words
A control system for operating a low pressure evaporative desalinator having a mechanism for introducing heat to a boiler chamber at temperatures below the atmospheric pressure boiling point of the raw water, a mechanism for drawing a vacuum within said boiler chamber, and a mechanism for pumping fresh water from said chamber, comprising: a main control switch having an ON position for activating and an OFF position for deactivating said desalinator; means for sensing the temperature of the raw water within said boiler chamber; means for sensing the vacuum within said boiler chamber; means responsively connected to said temperature sensing means and said switch for activating said vacuum drawing mechanism whenever said switch is in said ON position or said temperature sensing means monitors a temperature above a first predetermined level; means responsively connected to said switch and said vacuum sensing means for activating said heat introducing mechanism when said switch is in said ON position and said vacuum sensing means simultaneously monitors a pressure below a predetermined level which level is below atmospheric pressure; and means responsively connected to said switching means, said vacuum sensing means and said temperature sensing means for activating said fresh water pumping mechanism when said switch is in said ON position, when said temperature is simultaneously above a second predetermined level and when said pressure is simultaneously below said predetermined level.
Claim 3
Dependent Claim
66 words
A control system for operating a low pressure evaporative desalinator as defined in claim 1 wherein said desalinator includes a condenser for cooling vapors produced by boiling said raw water to produce fresh water, said means for activating said vacuum drawing mechanism additionally activating said condenser whenever said switch is in said ON position or said temperature sensing means monitors a temperature above said predetermined level.
Claim 4
Dependent Claim
77 words
A control system for operating a low pressure evaporative desalinator as defined in claim 1 wherein said desalinator includes a salinity monitoring device for controlling the flow of said fresh water pumped from said chamber and wherein said means for activating said fresh water pump additionally activates said salinity monitoring device when said switching means is closed, when said temperature is simultaneously above said second predetermined level and when said vacuum is simultaneously above said predetermined level.
Claim 5
Dependent Claim
63 words
A control system for operating a low pressure evaporative desalinator as defined in claim 1 additionally comprising: time delay means connected to said means for activating said heat introducing mechanism, said time delay means permitting continued actuation of said heat introducing mechanism, once actuated, when said vacuum sensing means monitors a vacuum below said predetermined level for less than a predetermined time period.
