Abstract
In one implementation, a substance removal apparatus may include a collection unit and a removal unit. The collection unit may have a structure forming a channel and an inlet to receive an exhaust from a print system. The removal unit may separate a substance from the exhaust and transfer heat from the exhaust to the print system. The removal unit may include a heat exchanger and an impaction mechanism.
Claims19
A substance removal apparatus for a print system comprising:
- a collection unit having a structure forming a channel, a portion of the structure forming an inlet to the channel to receive an exhaust from the print system, the exhaust to contain a substance;
- and
- a removal unit operatively coupled to the collection unit, the removal unit to separate the substance from the exhaust and transfer heat from the exhaust to the print system, the removal unit comprising:
- a heat exchanger to transfer heat from the exhaust to a gas;
- an impaction mechanism to impact the exhaust and coalesce the substance;
- a return channel to communicate with the print system;
- and
- a gas movement device to generate a flow of the exhaust through the heat exchanger and through the impaction mechanism to the return channel, the return channel to pass the exhaust, after removal of the substance by the inspection mechanism, back to the print system.
5 more elements
A system comprising:
- a print system to produce an exhaust having a substance;
- a collection unit operatively coupled to the print system, the collection unit including a structure forming a channel to receive the exhaust from the print system;
- a heat exchanger operatively coupled to the collection unit to receive the exhaust from the collection unit, the heat exchanger to condense the exhaust by transferring heat to a gas;
- an impaction mechanism operatively coupled to the heat exchanger to receive a portion of the exhaust discharged from the heat exchanger, the impaction mechanism comprising a mesh of fibers to remove the substance from the portion of the exhaust, to form an output exhaust;
- a return channel between the impaction mechanism and the print system;
- and
- a gas movement device to cause the exhaust to flow through the heat exchanger, the portion of the exhaust to flow into the impaction mechanism from the heat exchanger, and the output exhaust to flow into the return channel to return the output exhaust to the print system.
4 more elements
A method comprising:
- collecting exhaust from a print system by a collection unit operatively coupled to the print system, the exhaust containing a substance;
- and
- separating the substance from the exhaust by:
- transferring, by a heat exchanger, heat between the exhaust and a gas to condense the exhaust;
- impacting the exhaust from the heat exchanger on an impaction mechanism to collect the substance;
- and
- using a gas movement device, flowing the exhaust from the collection unit to the heat exchanger, flowing the exhaust from the heat exchanger to the impaction mechanism, and flowing the exhaust after removal of the substance by the impaction mechanism to a return channel to return the exhaust to the print system.
