Abstract
Abstract A reactor for use in analysis of polluted liquids, having a housing partitioned into an inner flow passage communicated with an inlet, and an outer flow passage surrounding the inner flow passage and flow connected therewith. A packing material is arranged in the inner and outer flow passages to define an inlet plenum zone in the inner passage. Means are provided for heating the packing material to a temperature at which a liquid sample is vaporized in the inlet plenum zone and reacts with a gas while flowing therewith through the inner and outer passage to an outlet of the outer passage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
340 words
A reactor which comprises a first housing, partition means disposed within said first housing to define therein an inner flow passage and an outer flow passage disposed in laterally surrounding relation to said inner flow passage and flow connected therewith, means defining an inlet in said first housing to accommodate the introduction therein of a liquid sample and a gas to be reacted with said sample, a packing material disposed in said inner flow passage to define therein an inlet plenum zone communicating with said inlet, and a packing material disposed in said outer flow passage, means defining an outlet in said first housing communicating with said outer flow passage, means operable to heat the packing material in said inner and outer flow passages to a temperature at which the sample is vaporized in said inlet plenum zone and the sample reacts with said gas while flowing therewith through said inner and outer passages in contact with the packing material, the gaseous and vapor reaction products of said sample and gas exiting the first housing through said outlet, said first housing having a cylindrical shell outer wall and a pair of plates connected each to a respective end of said outer wall, and said partition means including a cylindrical tubular inner wall extending between said plates and disposed in generally coaxial relation to said outer wall to define a cylindrical inner flow passage and an annular outer flow passage, the outlet of said first housing being through said outer wall, a second housing defining an outlet plenum chamber and connected at one end to said outer wall of the first housing for support thereby and communicating with said outlet thereof to receive said gaseous and vapor reaction products to cool same, said second housing having an outlet for the exits of such cooled reaction products as are not condensed to liquid, and separate outlet for drainage of such reaction products as are condensed to liquid, said second housing being inclined in a downward direction to facilitate drainage of such liquid.
Claim 2
Dependent Claim
340 words
A reactor which comprises a first housing, partition means disposed within said first housing to define therein an inner flow passage and an outer flow passage disposed in laterally surrounding relation to said inner flow passage and flow connected therewith, means defining an inlet in said first housing to accommodate the introduction therein of a liquid sample and a gas to be reacted with said sample, a packing material disposed in said inner flow passage to define therein an inlet plenum zone communicating with said inlet, and a packing material disposed in said outer flow passage, means defining an outlet in said first housing communicating with said outer flow passage, means operable to heat the packing material in said inner and outer flow passages to a temperature at which the sample is vaporized in said inlet plenum zone and the sample reacts with said gas while flowing therewith through said inner and outer passages in contact with the packing material, the gaseous and vapor reaction products of said sample and gas exiting the first housing through said outlet, said first housing having a cylindrical shell outer wall and a pair of plates connected each to a respective end of said outer wall, and said partition means including a cylindrical tubular inner wall extending between said plates and disposed in generally coaxial relation to said outer wall to define a cylindrical inner flow passage and an annular outer flow passage, the outlet of said first housing being through said outer wall, a second housing defining an outlet plenum chamber and connected at one end to said outer wall of the first housing for support thereby and communicating with said outlet thereof to receive said gaseous and vapor reaction products to cool same, said second housing having an outlet for the exits of such cooled reaction products as are not condensed to liquid, and separate outlet for drainage of such reaction products as are condensed to liquid, said second housing being inclined in a downward direction to facilitate drainage of such liquid.
Claim 3
Dependent Claim
60 words
A reactor according to claim 1 wherein said packing material in said inner flow passage is a plurality of balls disposed in contact with one another to establish voids accommodating fluid flow through said passage, said balls being located generally in the lower half of said inner flow passage to define an inlet plenum zone in the upper half thereof.
Claim 4
Dependent Claim
35 words
A reactor according to claim 1 wherein said packing material in said outer flow passage is a plurality of balls disposed in contact with one another to establish voids accommodating fluid flow through said passage.
