Heat exchanger of an air-conditioning system of a cabin of a transport vehicle, comprising: a primary circuit supplied by a first air flow (169), a secondary circuit supplied by a second air flow (168), a casing (161) defining an air-circulation enclosure (162), a primary circuit inlet box (164) allowing entry into said air-circulation enclosure, and a primary circuit outlet box (165) allowing exit from the air-circulation enclosure, characterized in that said inlet box (164) is mounted removably on said casing (161), and in that it houses a three-dimensional structure (163) forming a catalytic and/or adsorbent support for treating the air of said primary circuit, and a means for distributing said first air flow into said heat-exchange matrix.

An apparatus and method are provided for capturing and sterilizing contaminants, such as viruses and the like. Air containing the contaminants is drawn into the apparatus that comprises a housing having a customized number and arrangement of dissimilar treatment chambers to remove a particular contaminate targeted for removal. The treatment chambers are selected from a group of pre manufactured, self-contained chambers that are singularly or in combination inserted into the housing and within an air flow path created by a fan. The group of treatment chambers include a UV chamber, a temperature chamber and an ozone converter chamber. The customized arrangement of treatment chambers are each placed in the air flow path and programmed to provide customized sterilization of any type of contaminate while persons are present in the space being treated.

A corona plasma cell includes a polarized electrode and a ground electrode, including a cylinder and a porous film, with the cylinder having a low profile and the polarized electrode not entering the cylinder; a corona plasma dual element including a first cell, a second cell having such a structure, which first and second cell are symmetrically arranged; and finally a plasma reactor including a plurality of cells or dual elements.

Described is related to nano-structured composite materials for removing harmful chemical air pollutants and odors from the air to prevent people from breathing in disease-causing chemicals and provide them with clean indoor air. The nano-structured composite materials comprise nano-catalysts embedded in the pores of nano-structured substrate materials selected from the group consisting of nano-porous carbon, nano-porous rare earth oxide, nano-porous zeolite, nano-porous alumina and nano-porous silica. The nano-scale synergy of nano-catalysts and nano-structured substrate materials provides effective air filtration materials for the complete trapping and elimination of the full spectrum of chemical air pollutants including both organic and inorganic compounds and odors for indoor spaces, which HEPA or activated carbon filters cannot achieve.

An ionic oxidation refreshing system for refreshing an odorized item, comprising an enclosure with an airflow system to contact the odorized item on all sides; an ionization system that produces a positively charged ionized ozone gas mixture inside of the enclosure, killing germs, including odor-causing bacteria, viruses, molds, and fungus, and provides the odorized item inside the enclosure with a net positive charge; a filter that neutralizes and filters out any toxic by-products; an electrostatic liquid atomization system that creates a fine mist of a quick-cleaning solution, and, in conjunction with the airflow system, causes solution droplets to penetrate deep into the odorized item and agitate a surface of the odorized item, ensuring the formula is evenly delivered onto the odorized item without over saturating any area.

An exhaust dust removal system includes an electric field device (1021) and a cooling device. The electric field device (1021) has an electric field device inlet, an electric field device outlet, a dust removal electric field cathode (10212), and a dust removal electric field anode (10211). The dust removal electric field cathode (10212) and the dust removal electric field anode (10211) are used to generate an ionizing dust removal electric field. The cooling device is used to reduce the exhaust temperature before the electric field device inlet. The exhaust dust removal system may help reduce greenhouse gas emissions, and may also help reduce emissions of harmful gases and pollutants, which thereby makes the gas emissions more environmentally friendly.

An air ionization unit is provided to ionize air to remove particulates and to release cleaned air. Air moves into the air ionization unit where it may be first filtered by an air intake filter. The air is moved, preferably by a fan, into contact with an ion generator, where the air is ionized. One or more (such as two) other fans may be used to provide airflow to (1) at least partially remove ions emanating from the air that has been exposed to the ion generator, and (2) to push the cleaned air through one or more ozone filters and out of the air ionization unit. The air ionization unit may also include an outgoing air filter, and one or more doors to access the air intake filter and/or the air ionization unit.

An engine tail gas ozone purifying system and method. The engine tail gas ozone purifying system comprises reaction fields (220, 202) used for mixture reaction of an ozone stream and a tail gas stream. A large amount of urea does not need to be added and the purification effect is good.

An exhaust gas dust removal system, comprising a dust removal system inlet, a dust removal system outlet and an electric field apparatus, the electric field apparatus comprising an electric field apparatus inlet, an electric field apparatus outlet, a dust removal electric field cathode and a dust removal electric field anode, the dust removal electric field cathode and the dust removal electric field anode being used for producing an ionising dust removal electric field. A dust collection area of the dust removal electric field anode is larger than a discharge area of the dust removal electric field cathode, so that an asymmetric electrode attraction force is produced between the electrodes, to reduce electric field couplings.
