A scrubber system includes a liquid ring vacuum pump, a water tank and a surfactant column. The pump has a vacuum inlet port, an exhaust outlet port, and a water supply port. The water tank has an inlet port coupled to the exhaust outlet port of the pump, a water return port connected to the water supply port of the pump for supplying water to the pump, and a first overhead vapor port. In addition, the surfactant column has an inlet port connected to the overhead vapor port of the water tank and a second overhead vapor port. The pump draws air containing volatile organic compounds from a vapor space in a main tank that contains wastewater and pushes the air through the water tank, surfactant column and, optionally, a further carbon column. Volatile organic compounds are removed from the air before release into the atmosphere.

The present invention relates to the technological field of civil engineering, particularly to a dust reduction device for building engineering. The device includes a water tank with a controller and a booster pump, a driving mechanism enabling the device to cross obstacles, an adjustable spray mechanism with a mist intercepting mechanism, and an environment detection mechanism. The dust reduction device comprising the above components can move along the enclosure barrier to a target position for spraying according to real time requirements. The adjustable spray mechanism is configured in such a way that, when the wind force is between the specified minimum value and maximum value, and the wind direction is opposite to the spray direction, the mist intercepting mechanism is activated to avoid water mist blowing outside the construction site by wind and affecting the normal passage of pedestrians.

An automated end-to-end continuous purification system for the manufacture of therapeutic proteins to reduce complexity of manual process operations and minimize physical space requirements, such system comprising a housing containing a control system, a tray and a collection vessel, wherein the system comprises a series of four purification stages, each such stage comprising a product pump and protein product line, a buffer pump and buffer line, a flow kit, two to four pinch valves and a waste line, and all such purification stages are connected by a single protein product line and are operated simultaneously.

STAXLINK is a duct system and method for conveying exhaust gas from an exhaust pipe of an emissions source to a purification unit during an Emissions Reduction as a Service (ERaaS) operation. Example emissions sources include oceangoing vessels and buildings structures. The duct is temporarily installed onto the emissions source without a crane. The duct is supported by the emissions source itself for the duration of the ERaaS operation.

A carbon dioxide recovery method includes an adsorbing step of adsorbing carbon dioxide onto an adsorbent at a first location by using an air flow generated by a blower provided in a fluid device or an external air; a first transporting step of transporting the adsorbent which has adsorbed the carbon dioxide from the first location to a second location by a mobile object; and a second transporting step of transporting an adsorbent which has not adsorbed the carbon dioxide from the second location to the first location by a mobile object.

A device for filtering a urea-water solution in an SCR exhaust gas aftertreatment device for injecting the urea-water solution into an exhaust gas train. The filtering device includes a filter housing and a filter which is arranged in an interior of the filter housing. In order to provide a simpler filtration device in which the susceptibility to damage is reduced and the interchangeability of individual components is increased, a volume compensation foam is arranged between the filter housing and the filter, the volume compensation foam being detachably fastened to the filter such that it can be flushed around by the urea-water solution.

An automated end-to-end continuous purification system for the manufacture of therapeutic proteins to reduce complexity of manual process operations and minimize physical space requirements.

Provided is a household oxygen generator. The household oxygen generator includes a housing. A compression mechanism, a first air path module and an oxygen generation mechanism which are communicated in sequence are disposed in the housing. The first air path module includes a flow guide pipeline, a movable pipeline and a locking assembly. The movable pipeline is movably connected to the flow guide pipeline. The locking assembly is in transmission connection with the movable pipeline. The flow guide pipeline is connected to the oxygen generation mechanism. The locking assembly has a locking position and an unlocking position. When the locking assembly is in the locking position, the movable pipeline is clamped to or inserted into an air inlet of the oxygen generation mechanism. When the locking assembly is in the unlocking position, the movable pipeline is separated from the air inlet of the oxygen generation mechanism.
