Definitions
- the present invention broadly provides an improved method of altering a fluid-borne contaminant, and, more particularly, to an improved method for efficiently altering or converting a particulate, chemical or biological contaminant in a compressible gas stream to a less-objectionable form.
- the present invention broadly provides an improved method of altering a fluid-borne contaminant.
- the improved method broadly includes the steps of: providing a pump (21) having an inlet (22) and an outlet (23); connecting the pump inlet to a source (24) of contaminated fluid; operating the pump at a pressure ratio of at least 2.0 so as to sufficiently elevate the temperature of the fluid and contaminants passing through the pump; and controlling the time during which the temperature of the fluid and contaminants are so elevated; thereby to alter substantially all of the contaminants passing through the pump.
- the contaminants may be altered by chemical reduction, oxidization, combustion, heating, passivation, or some other process or means.
- the contaminants may include particulate material (e.g., asbestos, etc.), a biological agent (e.g., a spore, a bacteria, a virus, a pathogen, a fungus, a pollen, etc.), or some other substance.
- the fluid should include a compressible gas.
- the fluid may be entirely gaseous, or only partially gaseous.
- the contaminants may be entrained in the gas, or may be present in a liquid mixed with such gas.
- the pump may be a Roots-type positive displacement pump, a compressor, a piston-and-cylinder, or the like.
- the pressure ratio of the pump is the pressure at the pump outlet divided by the pressure at the pump inlet.
- the time of passage may be controlled by restricting the flow of fluid and contaminants passing through the pump, and/ or any associated upstream or downstream elevated temperature portion.
- the temperature of the fluids and contaminants should be heated to at least about 200°C at the pump outlet.
- the improved method may further include the additional steps of: providing a catalytic converter, and causing the flow of gas to pass sequentially through the pump and the catalytic converter.
- the catalytic converter may be arranged downstream of a pump, but this arrangement need not invariably obtain.
- a series of pumps may be arranged so as to be in series with one another.
- Contaminated fluid from the source is caused to pass sequen- tially through the pumps so as to alter the contaminants by multi-recompressive heating.
- the method includes the additional step of: preheating the temperature of the fluid entering the pump with heat provided from the temperature of fluid exiting the pump. If desired, a fuel or reagent can be entrained in, or atomized with, the fluid supplied to the pump.
- the method may further comprise the additional steps of: sampling the fluid exiting the pump to determine the extent to wl ich contaminants therein have been altered; and adjusting the operation of the pump (i.e., so as to selec- tively increase the temperature and/ or the time of passage) so that substantially all of the contaminants will be altered or converted by passing such contaminated fluid through the pump.
- the invention provides an improved method of altering a fluid-borne contaminant, which method includes the steps of: providing a pump having an inlet and an outlet; connecting the pump inlet to a source of contaminated fluid; operating the pump so as to elevate the temperature of the fluid and contaminants passing through pump to at least about 200°C; and controlling the time during which the temperature of theizid and contaminants are elevated; thereby to alter substantially all of the contaminants passing through the pump.
- the general object of the invention is to provide an improved method of altering a fluid-borne contaminant.
- Another object is to provide an improved method of selectively and con- trollably altering a fluid-borne contaminant, such as a particulate material, a biological agent (e.g., a spore, a bacteria, a virus, a pathogen, a fungus, a pollen, etc), a chemical agent, some other substance, or a combination thereof.
- a fluid-borne contaminant such as a particulate material, a biological agent (e.g., a spore, a bacteria, a virus, a pathogen, a fungus, a pollen, etc), a chemical agent, some other substance, or a combination thereof.
- Still another object is to provide an effective and low-cost method of remediating a contaminated fluid.
- Still another object is to provide an improved method of compressively heating a volume of gas, substantially uniformly and substantially instantaneously.
- Fig. 1 is a schematic of one form of apparatus for performing the improved method.
- Fig. 2 is a plot of temperature (left ordinate) and pressure ratio (right ordinate) versus time (abscissa), showing that the increase in temperature is substantially in-phase with a step change in pressure ratio.
- Fig. 3 is a plot of temperature ratio versus pressure ratio for a Roots-type pump or blower operated at two different rpms..
- Fig. 4 is a scanning electron micrograph of a test sample of air contaminated with Bacillus globigii (Bg) spores, prior to passing through the apparatus.
- Fig.5 is a scanning electron micro graph image showing the contaminated air depicted in Fig.
- Fig. 6 is a schematic view showing the improved apparatus arranged parallel with a conventional HNAC system used in association with a building.
- Fig.7 is a schematic view showing a downstream sensor as used to adjust the operation of the blower so as to alter or convert substantially all of the contaminants therein.
- the terms “horizontal”, “vertical”, “left”, “right”, “up” and “down”, as well as adjectival and adverbial derivatives thereof simply refer to the orientation of the illustrated structure as the particular drawing figure faces the reader.
- the terms “inwardly” and “outwardly” generally refer to the orientation of a surface relative to its axis of elongation, or axis of rotation, as appropriate.
- the present invention broadly provides an improved method of altering or converting a fluid-borne contaminant from one form to another.
- the improved method uses apparatus that is, for all intents and purposes, old, albeit such apparatus was not previously used for the purpose herein disclosed and intended. Indeed, the improved method deliberately misuses that known appa- ratus to achieve objectives that were avoided in the prior art.
- the invention provides an improved method of altering or converting a fluid-borne contaminant, which method comprises or includes the steps of: providing a pump having an inlet and an outlet; connecting the pump to a source of contaminated fluid; operating tr e pump at a pressure ratio of at least 2.0 so as to sufficient elevate the temperature of the fluid and contaminants passing through the pump; and controlling the time during which the temperature of the fluid and contaminants are elevated; thereby to substantially alter all of the contaminants passing through the pump.
- contaminant is intended broadly and generi- cally. It may include a particulate contaminant, such as an asbestos particle or the like.
- the fluid may include a biological agent such as a pathogen, pollutant, virus, fungus, mold, spore, or the like. It may include some other chemical, pollutant or contaminant. At least a portion of the fluid should be compressible. This fairly means that the fluid should have a gaseous component, if the fluid is not wholly gas. As used herein, the word "fluid" is generic to either a liquid or a gas. The improved method operates to volumetrically compress the gas, causing a substantially unifor increase in its temperature very quickly.
- the pump may be a Roots-type positive displacement pump or blower, a compressor, a piston-and-cylinder, or some other similar device.
- a Roots-type positive displacement pump sometimes known as a Roots Blower, refers to a device having two multi-lobed rotors or impellers arranged within an elongated casing or housing.
- the rotors or impellers are rotated in opposite directions, and closely interfit with one another, the angular walls of the casing, and the end walls of the casing.
- the pressure ratio is the pressure at the output of the pump divided by the pressure of the input of the pump.
- the time during which such fluid and contaminants are subjected to an elevated temperature may be regulated or monitored by means of adjusting the flow of contaminants through the apparatus, or by providing a heated tube downstream of the pump. It is presently preferred that the pump be operated at a pressure ratio of at least 2.0, or that the temperature of the outlet gas be at least about 200°C at the pump outlet.
- Bacillus globigii (Bg) spores, an anthrax simulant where killed by heating to about 200 °C in a single pass through a Roots-type positive displacement pump.
- a test bed arrangement of the present apparatus is generally indicated at 20.
- This device is shown as having a Roots-type pump or compressor 21, and an inlet 22 and an outlet 23.
- Contaminated fluid from a suitable source 24 is provided through a high-flow filter 25 to an inlet pipe 26, containing a lambda-square orifice flow meter 28 and a throttling valve 29 to the pipe inlet 22.
- the volume of the inlet fluid is compressed, and is discharged through the pump outlet 23 through a muffler or silencer 30.
- a portion of the fluid outlet stream is sampled, as indicated by block 31.
- Fig. 2 is a plot showing temperature (left ordinate) and pressure ratio (right ordinate) versus time.
- Fig.3 is a plot of temperature ratio versus pressure ratio for a Roots blower, such as shown Fig. 1, albeit operated at two different angular speeds.. This curve illustrates that as the pressure ratio increases, the temperature ratio also increases, albeit in a non-linear manner.
- Fig. 4 is a scanning electron micrograph showing a test sample containing a large number of Bg spores in a contaminated fluid sample provided to the inlet of the pump.
- Fig. 5 is a scanning electron micrograph of the flow at the fluid outlet.
- FIG. 6 is a schematic showing the improved apparatus as being operatively arranged in parallel with a conventional HN AC system 32 having an inlet 33 and an outlet 34 arranged to supply the outlet flow to a building 35.
- a conventional HN AC system 32 having an inlet 33 and an outlet 34 arranged to supply the outlet flow to a building 35.
- Pump 39 is provided through an inlet 40, and having an outlet 41. The outlet from the pump is provided to a catalytic con- verter 42 for conversion or alteration of the particular contaminant.
- a sensor 43 is arranged to sense the presence of contaminant in the outlet flow provided in outlet conduit 44, which is also provided to the building.
- valves 36 and 38 can be opened, and pump 39 disabled so as to permit normal use of the HNAC system.
- val s 36 and 38 may be selectively closed to divert flow to the pump.
- catalytic converter for treatment of the fluid contained therein.
- the catalytic converted could be positioned upstream of the pump.
- Fig. - 7 is a schematic view showing another form of the pump, this time indicated at 45, and catalytic converter 46 associated with a heat exchanger 48.
- the present invention broadly provides an improved method of altering a fluid-borne contaminant, which method includes the steps of: providing a pump having an inlet and outlet; connecting the pump inlet to a source of contaminated fluid; operating the pump at a pressure ratio of at least 2.0 so as to sufficiently elevate the temperature of the fluid and contaminants passing through the pump; and controlling the time during which the temperature of the fluid and contaminants are elevated; thereby to alter substantially all of the contaminants passing through the pump.
- the invention provides an improved method of altering a fluid-borne contaminant, which includes the steps of: providing a pump having an inlet and outlet; connecting the pump inlet to a source of contaminated fluid; operating the pump so as to elevate the temperature of the fluid and contaminants passing through the pump to at least 200°C and controlling the time during which the temperature of the fluid and contaminants are elevated, thereby to alter substantially all of the contaminants passing through the pump.
- the contaminants may be particulate or biological.
- the contaminants may be altered by chemical reduction, oxidization or combustion.
- the fluid must contain a compressible gas. However, the entire inlet flow need not to be gaseous in nature. The contaminants may be entrained in the gas.
- a fuel or reagent may be entrained in, or provided as an aerosol, to the gas.
- the pump may be Roots-type positive displacement pump, a compressor, a piston-and-cylinder, or some other type.
- the outlet flow from the pump may be provided to a catalytic converter, or may be caused to pass through another pump. Heat at the pump outlet may be extracted and feed back preheat the gas provided to the pump inlet.
- the fluid at the pump outlet may be sampled to determine the existing level of contamination, and the operation of the pump may be adjusted so that substantially of the contaminants are converted by passing through the pump.
