Abstract
Abstract A distillation purifying system including a section which creates a vacuum pressure that is transmitted throughout the system, a distillation/purification zone in which fluids to be distilled/purified are treated, and a collection zone in which the distilled/purified liquids are transferred. The system is effective for use with liquids, solutions, fluids and the like and can be used for water treatment as well as bodily fluid treatment.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
218 words
A vacuum distillation apparatus comprising: a vacuum means for generating vacuum pressure; a distillation and separation chamber having an evaporator chamber and a condensing means, said condensing means being in communication with said evaporator chamber; a vapor separation means and a heating means located in said evaporator chamber; a heat exchanger connected to said condensing means; a degassification tank connected to said evaporator chamber and said vacuum means; a liquid transfer means having a first end extending into liquid to be distilled and a second end opening into said evaporator chamber through said degassification tank; a discharge pipe connected to said evaporator chamber for draining non vaporized material from said evaporator chamber; a distillate trap connected between said condensing means and said vacuum means; a collection means connected to said distillate trap for collecting distillate that passes through said distillate trap; and a computer control means for ensuring that a vacuum level in said vacuum distillation apparatus corresponds to a latent heat of vaporization point which represents a set relationship with respect to the temperature of the liquid to be distilled before activating the heating means for use, wherein said liquid to be distilled passes through said liquid transfer means into said degassification tank, into said distillation and separation chamber and as distillate out of said distillate trap.
Claim 2
Dependent Claim
218 words
A vacuum distillation apparatus comprising: a vacuum means for generating vacuum pressure; a distillation and separation chamber having an evaporator chamber and a condensing means, said condensing means being in communication with said evaporator chamber; a vapor separation means and a heating means located in said evaporator chamber; a heat exchanger connected to said condensing means; a degassification tank connected to said evaporator chamber and said vacuum means; a liquid transfer means having a first end extending into liquid to be distilled and a second end opening into said evaporator chamber through said degassification tank; a discharge pipe connected to said evaporator chamber for draining non vaporized material from said evaporator chamber; a distillate trap connected between said condensing means and said vacuum means; a collection means connected to said distillate trap for collecting distillate that passes through said distillate trap; and a computer control means for ensuring that a vacuum level in said vacuum distillation apparatus corresponds to a latent heat of vaporization point which represents a set relationship with respect to the temperature of the liquid to be distilled before activating the heating means for use, wherein said liquid to be distilled passes through said liquid transfer means into said degassification tank, into said distillation and separation chamber and as distillate out of said distillate trap.
Claim 3
Dependent Claim
24 words
The vacuum distillation apparatus of claim 1 further comprising sensors connected to said computer control means for automated operation of the vacuum distillation apparatus.
Claim 4
Dependent Claim
25 words
The vacuum distillation apparatus of claim 1 wherein said distillate trap, said distillation and separation chamber, and said collection means are insulated and atmospherically sealed.
Claim 5
Dependent Claim
73 words
The vacuum distillation apparatus of claim 3 further comprising a third end of said liquid transfer means, said third end connecting to said heat exchanger; and a valved exit pipe having a first end which extends into said liquid to be distilled and a second end which connects to said heat exchanger, such that said liquid passes through said liquid transfer means into said heat exchanger and out of said valved exit pipe.
Claim 6
Dependent Claim
81 words
The vacuum distillation apparatus of claim 3 further comprising a closed and insulated tank for collection of non vaporized materials which have collected in the base of said evaporator chamber, said insulated tank being connected to said evaporator chamber through said discharge pipe and comprising valves and a sensor, said tank being connected through said valves to said evaporator chamber, and said vacuum means, said sensor working in conjunction with said computer means for the opening and closing of said valves.
Claim 7
Dependent Claim
30 words
