A sulfur trap provides separation of elemental molten sulfur from a process stream comprising a mixture of sulfur and associated tail-gases. The sulfur trap comprises a vertically-oriented cylindrical wall having a chamber for receiving the process stream, a float positioned in the chamber, the float attached to a float end of a lever, a nozzle insert attached to the distal end of the lever, and a lever fulcrum positioned intermediate the lever float end and the lever nozzle insert end. The float, lever, nozzle insert and outlet are constructed to allow the float position to control nozzle insert engagement of the outlet, particularly to close the outlet when the float is elevated by molten sulfur and to disengage from the outlet to allow discharge flow of liquid sulfur at a determined level of sulfur within the chamber. Embodiments of a method of separating liquid sulfur from gases are also provided.

The present invention relates to an apparatus and a method of cleaning particle loaded “dirty” air using a multi flow-splitter technology in combination with at least one cyclone system which requires minimal energy to operate due to low pressure drops used to generate the fluid flows whilst allowing to exert high centrifugal or G-Force on the infeed fluid stream. This further allows to operate the particle removal process such that conventional additional filter media become optional, such that the technology may operate a significantly reduced or even without the need for maintenance and/or repair. Low internal air turbulence ensures a very high separation efficiency. Optionally adding additional explosion safe low-energy down-stream filtration stages with variable speed system fan provides optimal operational performance and operational flexibility.

An air cleaner may include a filter case configured to introduce, by a suction force of an internal space, ambient air being discharged through a filter provided in the internal space as intake air from which foreign substances are removed; and a built-in valve built in the internal space of the filter case and configured to form an ambient air introduction path for introducing the ambient air and an additional ambient air introduction path separated from the ambient air introduction path and to open the additional ambient air introduction path so that the ambient air flows into through the additional ambient air introduction path when the suction force is increased.

A purification device for disinfecting and filtering intake air is disclosed. The purification device comprises a housing provided with a number of inlet perforations for allowing the intake air to enter the housing and a number of air outlet perforations for allowing air purified by the purification device to leave the housing. The purification device moreover comprises a fan arranged inside the housing to suck the intake air into the housing and blow the purified air out of the housing. The purification device further comprises an ultraviolet radiation lamp arranged inside the housing to irradiate the intake air. The purification device also comprises a high-efficiency particulate air (HEPA) filter arranged to filter the intake air before the intake air leaves the housing as purified air. The filter comprises a plurality of pleats arranged in such a manner that the angle between adjacent pleats is 30 degrees or less.
