Disclosed is a vehicle-mounted exhaust gas and air dedust removal system, comprising an exhaust gas inlet, an air inlet and an electric field device (1021). The vehicle-mounted exhaust gas and air dust removal system is capable of purifying exhaust gas and introduced air simultaneously.

An engine exhaust gas dust-removal system and method. The engine exhaust gas dust-removal system comprises an exhaust gas dust-removal system inlet, an exhaust gas dust-removal system outlet, and an exhaust gas electric field device. The engine exhaust gas dust-removal system has a better dust-removal effect, and can effectively remove particulate matters in engine exhaust gas.

An exhaust gas ozone purification method, specifically comprising: enabling a mixing reaction between an ozone stream and an exhaust gas stream, and removing nitric acid from mixed reaction products between the ozone stream and the exhaust gas stream by using an electrocoagulation device. The electrocoagulation device comprises: a first electrode (301) electrifying water spray of nitric acid; and a second electrode (302) applying an attraction force to the electrified water spray. The method can realize the purification of exhaust gas.

A novel device which can ensure safe and effective elimination of collected pathogens and avoid secondary toxins. The device is suitable for installation into various HVAC and air handling equipment to rid the air of dangerous viral agents. The destruction of pathogens is guaranteed by heating collecting surfaces sufficiently. Complete direct line of sight of the lamp to the filter is not required as is with UV light.

The present invention relates to: a device (1, 101, 151) for separating off liquid and/or particulate contaminants from a gas flow (7, 107), in which a flow path of the gas flow (7, 107) runs between at least one first electrode (9, 31, 109) acting as a counter electrode and at least one second electrode (11, 111, 51, 53, 57, 135, 135, 135, 155) acting as an emitter electrode and having an electrode end (71, 77, 90) oriented in the direction of the first electrode, and a direct-current voltage exceeding the breakdown voltage can be applied between the first electrode (9, 31, 109) and the second electrode (11, 111, 51, 53, 57, 135, 135, 135, 155) in order to form a stable low-energy plasma (41, 125), wherein the second electrode (11) extends substantially along a first axis (X) in a first direction and the first electrode (31) has at least one plateau region (33) which is arranged opposite the second electrode (11) and which extends at least regionally in a first plane running substantially perpendicular to the first direction (X); and a method for operating such a device.
