A plant for the absorption of individual components, such as pollutants or recyclable materials, in gases, in which an absorption solution is brought into contact with the gas in an absorption chamber, where the absorption solution is fed into the absorption chamber through spray nozzles and the gas can be fed into the absorption chamber from below through a vertical inlet duct, where the inlet duct is covered by a roof structure. The roof structure is made up of a large number of lamellae placed one on top of one another and with spaces in between.

The present disclosure generally relates to plant-based air purification systems and more particularly to wall mounted systems for removing impurities from indoor air using plants.

Disclosed is a flue gas purification tower, comprising a tower body, at least one gas inlet (1) disposed at the bottom of the tower body, at least one gas outlet (2) disposed at the top of the tower body, at least one active coke layer (3) located inside the tower body, and a baffle plate (4) arranged in a place where the flow direction of the flue gas from the gas inlet changes. The baffle plate (4) is a straight plate, an arc plate, a straight-and-arc plate or a straight-arc-straight plate, wherein the straight-and-arc plate comprises a straight segment and an arc segment connected with each other; and the straight-arc-straight plate comprises a straight segment in the vertical direction, a straight segment in the horizontal direction, and an arc segment connected between the two straight segments.

According to embodiment, a carbon dioxide capturing system cools a regenerator discharge gas discharged from a regenerator 5 containing carbon dioxide by a cooling unit 8, and then sends the gas to a cleaner 9. The cleaner 9 receives condensed water generated from the regenerator discharge gas cooled by the cooler 9, and a gaseous cooled regenerator discharge gas, and cleans the cooled regenerator discharge gas by a cleaning liquid. The cleaner 9 has a first liquid reservoir 9b configured to store the condensed water, and a second liquid reservoir 9c configured to store the cleaning liquid having cleaned the cooled regenerator discharge gas.

An improved cluster-supporting catalyst has heteroatom-removed zeolite particles, and catalyst metal clusters supported within the pores of the heteroatom-removed zeolite particles. A method for producing a cluster-supporting catalyst includes the following steps: providing a dispersion liquid containing a dispersion medium and the heteroatom-removed zeolite particles dispersed in the dispersion medium; and in the dispersion liquid, forming catalyst metal clusters having a positive charge, and supporting the catalyst metal clusters within the pores of the heteroatom-removed zeolite particles through an electrostatic interaction.

An air purifier comprising: a housing provided with air inlets and air outlets and defining an accommodating cavity, wherein the air inlets are located on the side walls of the housing; a water supply module arranged within the accommodating cavity and defining a water storage cavity; a purifying module arranged within the accommodating cavity and located on the water supply module, the purifying module comprising: a purifying assembly rotatably disposed within the accommodating cavity, a water distribution assembly for guiding water in the water supply module to flow upwards and distributing water to the purifying assembly, and a driving device located on the purifying assembly and connected with the purifying assembly; and an air discharge module disposed within the accommodating cavity and located on the purifying module.

Compact membrane evaporative chillers, methods for cooling a process fluid (e.g., air) using a compact membrane evaporative chiller, and air conditioning systems and methods that include a compact membrane evaporative chiller are disclosed herein. Compact membrane evaporative chillers as disclosed herein can advantageously reduce or eliminate power consumption needed to circulate a working fluid.
