A diffuser includes a first tube and a second tube. The first tube includes a key and defines a first opening. The second tube is inserted through the first opening. The second tube defines a notch. The key is inserted into the notch.

An air filtration system includes a filtration device having a filter element and a blower, a dispersion casing defining an internal cavity having an inlet fluidly coupled to the blower of the filtration device and an outlet leading to the ambient environment, a duct fluidly coupling the blower of the filtration device to the inlet of the dispersion casing, and a flow reducing feature configured to cause the flow of air to have a reduced flow velocity at the outlet of the dispersion casing in comparison to the inlet of the dispersion casing.

An extraction system is designed for metal working and other applications. The system may comprise a blower that delivers a positive pressure airflow to a hood that creates an air region for removal of airborne components from a work area. Return air is filtered in a filter region, and debris removed may be separated by a baffle in the filter region to limit re-uptake of the debris by the blower during operation of the system.

A cleaner casing is fitted to a fan casing for covering an air cooling fan for an engine. A cleaner chamber is formed between the fan casing and the cleaner casing. The cleaner chamber accommodates therein a cylindrical filter element. The filter element purifies air which will becomes an intake air for the engine. In an outer periphery of the cleaner chamber, a swirling passage is formed. An air outside the fan casing is captured into the switching passage through a suction opening. The swirling passage allows the air to be passed onto a hollow portion of the filter element after the air has been swirled around the filter element thereby.

A method and apparatus for an inline air purification system is described herein. An example apparatus includes a housing, a high-velocity air flow guide, a filter assembly, and a fan. The high-velocity air flow guide includes a first portion and a second portion. The first portion is configured to form a passage within the housing, and the second portion is configured to divert and accelerate air flow of the ambient air from the passage to a chamber of the housing. The filter assembly includes one or more filtering elements configured to receive the ambient air from the chamber. The fan is configured to draw the ambient air from the chamber through the filter assembly and to generate processed air from the ambient air. The housing is located in an HVAC duct, and occupies only part of the cross-sectional area of the duct. The remaining area of the duct accommodates bypass air flow to a primary fan in the HVAC system.

The present invention provides an air purifier that includes: a purifier body; a first air blower which is provided in the purifier body to introduce, purify and discharge outside air; an air guidance part which is provided on the movement path of the air discharged from the first air blower and is pivotably coupled to the upper end of the purifier body to guide an air discharge direction; and a second air blower which is installed on the air guidance part to blow air.

Electronic device processing assemblies including an EFEM with at least one side storage pod attached thereto. The side storage pod has a side storage pod container. A supply conduit extends between an upper plenum of the EFEM to the side storage pod container. A fan causes purge gas to simultaneously flow into the EFEM chamber and into the side storage pod container. The fan also causes recirculation of the purge gas from the EFEM chamber. Methods of operating EFEMs and EFEMs are also disclosed.

The present application provides a mobile selective catalyst reduction system for use at a remote location. The mobile selective catalyst reduction system may include a first trailer with an ammonia delivery system and a tempering air system mounted thereon in whole or in part and a second trailer with a selective catalyst reduction section mounted thereon in whole or in part. The ammonia delivery system, the tempering air system, and/or the selective catalyst reduction section are permanently mounted on the first trailer or the second trailer for use at the remote location.

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.

A housing of a liquid separation device that includes an inlet for the gas-liquid mixture and a set of integrated components, the set of integrated components includes a liquid separator vessel to separate liquid from the gas-liquid mixture, where the liquid separator vessel includes an entry port for the gas-liquid mixture, a liquid outlet port, and a gas outlet port. The set of integrated components further includes a set of channels, where a wall of each channel is part of the housing and the set of channels includes an inlet channel to guide the gas-liquid mixture from the inlet of the housing to the entry port of the liquid separator vessel and an outlet channel to guide gas from the gas outlet port away from the liquid separator vessel. The set of integrated components includes a liquid buffer tank that allows liquid to flow through an opening in the wall.
