Patent ID: 7721975

Claim:
A method of deicing surfaces of highways using hot saturated salt brine comprising: (a) placing salt blocks and water into an emptied brine tank; (b) generating hot brine by: i) starting a 220 volts electrical generator to generate an electrical voltage and connecting the voltage from the generator to an oil burner located at a hot water generator to heat water within the hot water generator, wherein the voltage supplying to the oil burner is reduced to 110 volts from the 220 volts generator; ii) energizing a low voltage pendant remote control to control solenoid valves and a 220 volts hot water circulation pump; iii) initializing voltage from the 220 volts electrical generator to the 220 volts hot water circulation pump to circulate water from the brine tank to the hot water generator and hot water from the hot water generator to a heat exchanger and the brine tank; wherein the circulating water is circulated via a plurality of half inch inside diameter stainless steel pipes; iv) mixing the salt and water within the brine tank with the hot water from the hot water generator until all the salt blocks are dissolved; v) adding molasses and magnesium chloride to the brine tank; vi) placing additional salt and water to the brine tank to maintain the brine tank at a full level; (c) supplying diesel fuel to a fuel tank located at the hot water generator and a fuel tank located at the 220 volts electrical generator; (d) regulating pressure of the circulating water with a bladder tank; (e) controlling the hot brine delivery rate to a spray boom with a plurality of half inch inside diameter low voltage solenoid valves (f) controlling hot brine delivery to the 220 volts circulation pump, brine tank and the spray boom with a plurality of half inch inside diameter stainless steel ball valves; (g) spraying hot brine to surfaces of highways with a plurality of half inch pipe thread stainless steel jet spray nozzles that are attached to the spray boom; (h) supplying hot brine to a hose reel system to spray hard to reach areas; (i) preventing spray drifting at the spray boom with a curtain surrounding the spray booms, wherein the curtain consisting of either burlap material or a used conveyor belt; (j) providing a circuit breaker panel for controlling of the 220 volts voltage to the circulating pumps, the hot water generator, and a float switch in the brine tank; (k) weatherproofing an electrical panel that contains electrical connections for the hot water generator and circulating pump; and (l) controlling pressure of the hot brine that is being delivered to the spray nozzles that are located at the spray boom with a pressure control switch.
