Abstract

Abstract There is disclosed a method for the removal of liquid or solid particles from a volume of gas by generating a multiplicity of charged, individual bubbles, the bubbles being substantially larger than the particles, and introducing the charged bubbles into the volume of gas. The bubbles are either hollow liquid bodies or hollow solid bodies. Means are also disclosed for generating and electrically charging bubbles. According to a first embodiment of the invention, the particles are fog droplets and the method and means are used to disperse the fog. According to a second embodiment, the particles are dust particles which exist in the atmosphere, and the method and means are used to collect and remove the dust. According to a third embodiment, the method and means are used to clean dust particles from effluent gases such as those resulting from combustion processes. According to a fourth embodiment, the method and means may be used to collect particles during chemical manufacturing processes.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 13 words
A method according to claim 1 wherein said bubbles are hollow, liquid bodies.
Claim 2
Dependent Claim 13 words
A method according to claim 1 wherein said bubbles are hollow, solid bodies.
Claim 3
Dependent Claim 12 words
A method according to claim 1 wherein said particles are dust particles.
Claim 4
Dependent Claim 21 words
A method according to claim 1 wherein said particles are fog droplets and wherein said volume of gas is the atmosphere.
Claim 5
Independent Claim 57 words
A method for the dispersal of fog comprising the steps of: generating a multiplicity of charged bubbles, said bubbles being substantially larger than the fog droplets; dispersing said charged bubbles into said fog whereby said bubbles electrostatically attract said fog droplets; and permitting said bubbles with said fog droplets to coalesce and precipitate out of said fog.
Claim 6
Dependent Claim 44 words
A method according to claim 6 wherein the step of dispersing said charged bubbles into said fog comprises the step of: dispersing said bubbles into the atmosphere upwind of the area containing said fog whereby said bubbles drift with the wind into said fog.
Claim 7
Dependent Claim 27 words
A method according to claim 6 wherein the polarity of the charge on said bubbles is opposite to the polarity of the charge on said fog droplets.
Claim 8
Independent Claim 65 words
A method for the dispersal of a liquid or solid particle mist during chemical manufacturing processes comprising the steps of: generating a multiplicity of charged, individual bubbles, said bubbles being substantially larger than the particles in said mist; introducing said charged bubbles into said mist whereby said bubbles electrostatically attract said particles; and permitting said bubbles with said particles to precipitate out of said mist.
Claim 9
Independent Claim 65 words
A method for the removal of liquid or solid particles from a volume of gas comprising the steps of: passing said volume of gas through a chamber; introducing a multiplicity of charged, individual bubbles into said chamber, said bubbles floating along with said volume of gas and attracting said particles; and removing said bubbles with said particles from said volume of gas by conventional means.
Claim 10
Dependent Claim 26 words
Apparatus comprising: means for generating a multiplicity of bubbles; and means for substantially increasing the electrical charge on said bubbles that naturally occurs during generation thereof.
Claim 11
Dependent Claim 26 words
Apparatus according to claim 11 wherein said means for electrically charging said bubbles comprises: means for establishing an electrostatic field, said bubbles passing through said field.
Claim 12
Dependent Claim 37 words
Apparatus according to claim 11 wherein said means for substantially increasing the electrical charge on said bubbles is operative to increase, by several orders of magnitude, the electrical charge that naturally occurs during generation of said bubbles.
Claim 13
Independent Claim 65 words
A method for the removal of liquid or solid particles from a volume of gas comprising the steps of: generating a multiplicity of charged, individual bubbles, said bubbles being substantially larger than said particles; introducing said charged bubbles into said volume of gas whereby said bubbles electrostatically attract said particles; and removing said bubbles with said particles from said volume of gas by conventional means.
