Definitions
- Water purification technology is rapidly becoming an essential aspect of modem life as conventional water resources become increasingly scarce; as municipal distribution systems for potable water deteriorate with age; as increased water usage depletes wells and reservoirs, causing saline water contamination; and as further contamination occurs in conventional resources from intensive agriculture, from gasoline additives, and even from heavy toxic metals, leading to increasing and objectionable levels of germs and bacteria, salts, MTBE, chlorates and perchlorates, arsenic, mercury, and chemicals used to disinfect potable water, such as chlorinated compounds.
- RO reverse osmosis
- filtration and chemical treatment rarely are able to handle the diverse range of water contaminants, and even though they are commercially available, they often require multiple treatment stages or combination of various technologies to achieve acceptable water quality.
- UV light irradiation or ozone treatment can be effective against viruses and bacteria, but seldom remove other contaminants, such as dissolved gases, many salts, hydrocarbons, and insoluble solids.
- Most distillation technologies are generally superior at removing multiple contaminants, but unless they include selective steam separation systems, are still unable to handle all types of contaminants.
- the feed solenoid valve described in US Patent 6,663,770 is connected to a float valve in the boiler, instead of a pressure differential sensor as in the present invention.
- float valves Being mechanico-electrical devices that operate at boiling temperature, float valves suffer from reliability issues related to abrasion, fatigue, and dimensional stability.
- U.S. Patent 5,968,321 effects the control of the boiler level by means of a vertical sight-tube, which requires either visual monitoring of that function and is, thus, not a fully automated operation, or actuates an electrical photo-sensor signal that controls the inlet water valve.
- U.S. Patent 6,582,563 describes an inlet solenoid valve that controls the inflow of water into a control tank that regulates the boiler level in a distillation system, and an electronically controlled drain valve that is operated by means of a timer.
- Both, U.S. Patents 6,358,371 and 6,030,504 describe an electrical control system that includes a heater thermostat to control the boiler heater and a fan thermostat to control the cooling of a condenser.
- U.S. Patent 6,009,238 describes an automatic shut-off thermostat to prevent a boiler in a distillation system from going dry.
- U.S. Patent 5,833,812 describes a power unit for applying a voltage potential to heating probes immersed in a boiler, and a selector control for maintaining the water level in a boiler.
- U.S. Patent 5,609,732 describes a thermostatic control to prevent the boiler from running dry during distillation.
- U.S. Patent 5,286,350 describes float valves for controlling the water level in the boiler.
- U.S. Patent 5,059,287 describes a temperature sensor above the water in the boiler to interrupt power input to the boiler.
- U.S. Patent 4,415,075 describes a float switch and a low-level safety switch to control the level of water in a boiler.
- U.S. Patent 4,110,170 describes a temperature sensor at the outlet of a boiler to control the inlet flow of water into the boiler.
- U.S. Patent 3,980,526 describes a float sensor that is not directly linked to the inlet water flow into the boiler, but to a tubular stem.
- the objective of the present invention is to provide a fully automated water processing control system, particularly one designed to operate with sophisticated water distillation systems that are continuous and that include degassing as well as selective steam separation features.
- the operation of the boiler has three separate controls. It is controlled against running dry by a thermal overload switch. The proper level of water in the boiler is controlled by a boiler pressure switch that actuates a solenoid that controls the flow of inlet water. And the boiler is periodically drained by means of a boiler drain solenoid.
- the operation of the product water tank is subject to three additional controls. There is a product level switch that prevents the product tank against overflow. A timer delay relay prevents water produced during transient conditions from entering the product container by means of a product output solenoid that directs product water either to the product container or a waste stream.
- the overall system has a manual reset switch that resets the whole system to an initial state and three indicator lights that provide continuous operation al status. And to protect against electrical shorts, there is an overall power input fuse that protects against electrical shorts.
- FIGURE 1 is a schematic and assembly diagram of the invention.
- FIGURE 2 lists the control system input signals (INPUTS) and output controls (OUTPUTS) used by the system.
- FIGURE 3 is the control system state diagram.
- the invention comprises a fully automated system for controlling water purification units, particularly those that utilize distillation technology. Adequate control of distillation units is not trivial when such type of equipment operates continuously and must ensure proper product quality regardless of the contaminants present in the input water.
- the controls required in a sophisticated water distillation system must address each individual treatment stage in the distillation unit, which normally comprise a boiler for generating steam, a selective steam separation stage, and condensation of clean steam into final pure water. Given the sequence of treatment stages, the controls provided in the present invention are mechanical, electrical, and electro-mechanical in nature.
- Figure 1 illustrates the embodiment of multiple controls in the present invention and provides an example of an assembly diagram.
- AC power is supplied by a standard three-pronged "AC PLUG”.
- the "FUSE” (2) protects the overall circuit from shorts.
- a manual "RESET SWITCH” (3) enables the user to override the automatic controls and reset the system to an initial state.
- a "THERMAL OVERLOAD SWITCH” (1) normally osed, is located on the BOILER near the HEATER and will open circuit if the BOILER reaches an over- temperature condition.
- the "PRODUCT LEVEL SWITCH” (4) monitors the output water container level and will open when the container is full.
- the "BOILER PRESSURE SWITCH” (5) is a differential pressure switch which maintains the correct level in the BOILER.
- the "INLET WATER SOLENOID” (6) controls the flow of inlet water into the system.
- the "HEATER” (7) is an electrical heating element that heats water in the BOILER to boiling temperature.
- the “BOILER DRAIN SOLENOID” (8) controls the draining of water from the BOILER.
- the “TIMING DELAY RELAY” (9) generates a delayed timing pulse upon application of power to the input. The pulse delay time is set by a variable resistor.
- the "PRODUCT OUTPUT SOLENOID” (10) controls the flow of water to either the OUTPUT WATER CONTAINER or to a waste container or tube.
- the water processing unit is composed of a BOILER, STEAM STRIPPER AND SEPARATOR, AND CONDENSER units. Output water from the OUTPUT WATER CONTAINER is dispensed by the OUTPUT WATER FAUCET.
- the Control System operates in 3 distinct states: "OFF”. This is the “Control state,” when no power is applied, RESET SWITCH is activated, or output water container is full (PRODUCT LEVEL SWITCH opened). In this state, the HEATER is turned off, the inlet water is shut ⁇ ff (INLET WATER SOLENOID is closed), and the BOILER DRAIN SOLENOID is opened, thereby draining the BOILER. This is the non- operational state of the system, which is indicated when the POWER INDICATOR is not lit.
- HEAT This is the Control state when power is applied or RESET SWITCH is released and water processing is initiated.
- the HEATER is turned on, the inlet water is turned on (INLET WATER SOLENOID is opened), and the BOILER DRAIN SOLENOID is closed (thereby filling the BOILER), and product output from the condenser is directed to the waste container or tube (PRODUCT OUTPUT SOLENOID is opened).
- the BOILER PRESSURE SWITCH operates independently, and monitors pressure difference from the BOILER DRAIN and BOILER to control the water level in the BOILER.
- the BOILER PRESSURE SWITCH controls the INLET WATER SOLENOID, so that water level in the BOILER is actively monitored. This state is indicated when the HEAT INDICATOR is lit.
