A heat exchange apparatus for removing magnetic particulates from a gas stream, including a rotating element basket having a regenerative heat exchanger and at least one magnetic element. A method of removing magnetic particulates from a gas stream, including heating the regenerative heat exchanger during a first portion of a cycle as a segment of the rotating element basket passes through a first zone wherein contact is made with a flue gas thereby accumulating any magnetic particulates as they are attached to the magnetic element. Then cleaning a portion of the magnetic element during a second portion of the cycle. And cooling the regenerative heat exchanger and simultaneously heating an inlet air stream during a third portion of the cycle as the segment of the rotating element basket passes through a third zone wherein fluidic contact is made with the air inlet stream.

Apparatus uses hydrophobic synthetic beads to recover mineral particles in a slurry. The synthetic beads and the slurry are mixed into a mixture for processing. The apparatus has an interaction vessel installed in a section of pipeline. The interaction vessel is made from a pipeline folded or coiled into a compact struction having a continuous flow path. The interaction vessel has an input to receive the mixture of slurry and synthetic beads. The folded or coiled structure is used to increase the residence time of the mixture in the flow path, allowing more time for the mineral particles in the slurry to attach to the surface of the synthetic bead, while maintaining a small footprint. The interaction vessel may be formed from a number of loops of pipe section. The interaction vessel may be formed from one or more folded structures.

The present disclosure relates to a filter, which comprises a housing, a protective bushing, a magnetic bar and a filter screen. The protective bushing, the magnetic bar and the filter screen are disposed in the housing. The protective bushing comprises a cavity and a channel. The channel is disposed along the axial direction of the cavity. The advantageous effects of the filter according to the present disclosure lies in that: the magnetic bar inside the filter can adsorb metal impurities in the water in the channel; and the channel is in S shape which can increase the length of the flow path of the water so that the metal impurities in the water can be guaranteed to be sufficiently adsorbed by the magnetic bar; and the filter screen can filter out non-metal impurities in the water. An exhaust valve provided at the top of the protective bushing can keep the balance between the air pressure inside the filter and the air pressure outside the filter, which can ensure that the water can flow out and in smoothly. The filter is attached with an operating handle. If the user wants to disassemble the filter to clear up the metal impurities and non-metal impurities in the filter, he can disassemble the filter by means of the operating handle without the need of professional operator, which is convenient and simple.

Provided herein are systems, apparatus, and methods for extracting pure oxygen from a liquid. In some embodiments, a system for extracting oxygen from a liquid comprises a separator configured to allow a liquid to pass therethrough and to produce a liquid mixture comprising the liquid having at least a portion of oxygen removed therefrom. The separator comprises a wall surrounding an interior portion of a tube, the wall having at least one aperture formed therein. The separator also comprises at least one magnet positioned adjacently to the at least one aperture having a north pole end and a south pole end forming a magnetic field gradient therebetween and extending into an interior portion of the tube. The system also comprises a storage tank fluidly coupled to the at least one aperture and configured to store the at least a portion of oxygen removed from the liquid via the separator.

A system for eliminating unexploded ordnance from a mixture. The system includes a separation plant, including a crusher, a magnetic separation station, and a screen plant. The crusher reduces the size of pieces in the mixture, the magnetic separator separates pieces containing a significant amount of ferrous metal, and the screen separates small pieces from larger pieces. The fine output of the screen is composed of pieces that are sufficiently small to pose little hazard; they may be further subjected to heat treatment. Large pieces containing ferrous metal, or large pieces containing nonferrous metal, may be explosive and are transported, using an unmanned machine, to an inspection plant where they are sorted and where any unexploded ordnance is identified and disposed of. The separation plant is sufficiently distant from the inspection plant that an explosion at the separation plant does not pose a hazard to personnel at the inspection plant.

Black powder flowing with hydrocarbons in a hydrocarbon pipeline is converted into a magnetorheological slurry by implementing wet scrubbing in the hydrocarbon pipeline. A flow of the magnetorheological slurry through the hydrocarbon pipeline is controlled.
