Publication number: 20210223755Abstract: A method for fabricating a component of an abatement apparatus is disclosed. The method comprises: meshing a 3D model representation of a component defining a reaction chamber of an abatement apparatus based on specified component characteristics to define an optimised finite element representation of the component; and fabricating the optimised finite element representation. In this way, a 3D model of a component of an abatement apparatus can be generated from which its performance can be modelled. Particular characteristics of the component may be defined which affect the operation of the abatement apparatus. Those characteristics may then be used to generate the optimized finite element representation of the component which has those characteristics using meshing (it will be appreciated that meshing is the operation of representing a geometric object as a set of finite elements).Type: ApplicationFiled: May 13, 2019Publication date: July 22, 2021Inventors: Andrew James Seeley, Gary Peter Knight, Duncan Michael Price, Mayank Verma

Patent number: 10767860Abstract: A treatment apparatus for treating an effluent gas includes a combustion chamber; a burner; an inlet for receiving secondary combustion air; an exhaust gas outlet for outputting exhaust gases from the combustion chamber; and a heat exchanger. The heat exchanger is configured to exchange heat between a first fluid and a second fluid flowing through respective first and second fluid flow paths. The first fluid flow path is connected to the inlet and the second fluid flow path is connected to the outlet such that the exhaust gases received at the outlet flow into the second fluid flow path. The heat exchanger comprises a fluid flow communication path for providing a path for flow of a portion of the exhaust gases from the second fluid into the first fluid; and at least one inlet aperture for inputting the first fluid to the combustion chamber.Type: GrantFiled: October 27, 2016Date of Patent: September 8, 2020Assignee: Edwards LimitedInventor: Gary Peter Knight

Patent number: 10702824Abstract: Venturi Scrubbers are used to separate particulate from a large range of fluids. Many provide additional liquid and/or gas to drive the fluid and aid in the removal of particulate. The present invention provides a liquid ring pump through which the fluid to be treated is first passed and then exhausted, with additional work fluid to a Venturi scrubber such that the particulate can be separated from the exhaust fluid.Type: GrantFiled: June 15, 2016Date of Patent: July 7, 2020Assignee: Edwards LimitedInventors: Gary Peter Knight, Andrew James Seeley, Duncan Michael Price

Patent number: 10661217Abstract: The abatement apparatus includes a porous element at least partially defining a treatment chamber and through which treatment materials pass for introduction into the treatment chamber for treatment of an effluent gas stream; and an infra-red heating device operable to emit infra-red energy to heat the porous element which heats the treatment materials as they pass through the porous element into the treatment chamber. In this way, infra-red energy, rather than combustion, can be used to raise the temperature within the treatment chamber in order to treat the effluent gas stream. This allows the apparatus to be used in environments where no fuel gas exists or where the provision of fuel gas is considered undesirable. Also, heating the treatment materials as they pass through the porous sleeve, rather than simply using radiant heat to heat the treatment chamber enables significantly more energy to be imparted into the treatment materials.Type: GrantFiled: August 22, 2016Date of Patent: May 26, 2020Assignee: Edwards LimitedInventors: Duncan Michael Price, Gary Peter Knight

Patent number: 10655626Abstract: Liquid ring pumps are used to pump a variety of fluid types. Corrosive fluids are easily handled by the work fluid but can cause corrosion of pumping mechanisms. The present invention provides a magnetically driven liquid ring pump with corrosion resistant pumping mechanisms which achieves a longer time between service intervals.Type: GrantFiled: June 15, 2016Date of Patent: May 19, 2020Assignee: Edwards LimitedInventors: Gary Peter Knight, Andrew James Seeley, Geoffrey Young, Duncan Michael Price

Patent number: 10625205Abstract: Dry pumps are used to pump a variety of gas mixtures from the semiconductor industry. The present invention provides a liquid ring pump located between the dry pump and an abatement device to remove soluble corrosive materials prior to the exhaust gases entry to the abatement device, the work fluid exhausted from the liquid ring pump being separated from the gas prior to entry to the abatement device.Type: GrantFiled: June 15, 2016Date of Patent: April 21, 2020Assignee: Edwards LimitedInventors: Christopher Mark Bailey, Clive Marcus Lloyd Tunna, Jack Raymond Tattersall, Ingo Stephen Graham, Michael Roger Czerniak, Gary Peter Knight, Darren Mennie, Duncan Michael Price, Derek Martin Baker, Andrew James Seeley

Patent number: 10099169Abstract: Liquid ring pumps are used to pump a variety of fluid types. The present invention provides a two stage liquid ring pump through which an exhaust gas comprising compounds to be destroyed is passed. The exhaust gas passes through the first stage to a gas abatement device, following which it is passed back to the second stage of the liquid ring pump for removal of the compounds formed in said abatement device. The stages of the liquid ring pump may be adjustable.Type: GrantFiled: June 15, 2016Date of Patent: October 16, 2018Assignee: Edwards LimitedInventors: Andrew James Seeley, Duncan Michael Price, Gary Peter Knight

Patent number: 8394179Abstract: A method is described for treating a gas stream containing a flammable gas, such as hydrogen or a hydrocarbon gas. The gas stream is conveyed to a liquid ring pump (18), to which a gaseous oxidant and water are supplied. The water and the gas stream are discharged from the pump (18), with the discharged gas stream being subsequently separated from the liquid, and conveyed to a pyrolysis device (42) for pyrolysing the flammable gas and the oxidant. Any particulates and acidic species within the gas stream are retained by the water within the liquid ring pump to inhibit corrosion or blockage of the pyrolysis device (42). A filter or other device (40) may be provided to remove water from the gas stream before it enters the pyrolysis device (42).Type: GrantFiled: January 23, 2008Date of Patent: March 12, 2013Assignee: Edwards LimitedInventors: James Robert Smith, Gary Peter Knight
