The apparatus for diluting exhaust gas according to an exemplary embodiment of the present invention includes a stagnant air forming unit configured to form stagnant air by decelerating a flow velocity of introduced exhaust gas, an ejector unit connected to a front end of the stagnant air forming unit and configured to discharge the exhaust gas to a front, and a dilution unit coupled to a front end of the ejector unit.

Apparatus for diluting exhaust gas

An exemplary embodiment of the present invention relates to an apparatus and method for removing nitrogen oxide from exhaust gas. The apparatus for removing nitrogen oxide from exhaust gas includes: a chamber through which exhaust gas is introduced and discharged; a nozzle injecting a solution, which reacts with the exhaust gas introduced into the chamber, into the chamber; and an electric dust collecting unit installed at a rear end of the chamber to be supplied with the exhaust gas processed in the chamber and including a discharge unit and a dust collecting unit.

Apparatus and method for removing nitrogen oxide from exhaust gas

An exhaust gas dilution device according to an exemplary embodiment of the present invention includes a head part, ejector unit, a nozzle part, and a dilution part. The head part has a space part into which an exhaust gas flows and a through-hole formed through the center axis direction to be connected to the space part. The ejector unit is coupled to the head part and has a first discharge hole formed passing through the center axis direction to be connected to the through-hole and connected to a first inlet to which primary dilution air is supplied. The nozzle part is inserted into a first discharge hole through the through-hole and has a second discharge hole that penetrates in the center axis direction so that the exhaust gas flowed into the space part is sucked and ejected into the first discharge hole as the primary dilution air moves through the first discharge hole. The dilution part has a first flow path part into which a primary dilution gas, which is generated and discharged after the exhaust gas and the primary dilution air are mixed in the first discharge hole, flows, and a second flow path part connected to the first flow path part and guiding secondary dilution air to be mixed with the primary dilution gas, and generates a secondary dilution gas as the primary dilution gas and the secondary dilution air are mixed.

Exhaust gas dilution device

There is provided an electrostatic precipitation device of explosive exhaust gas particles that can remove by unipolar charging a particulate material such as SiOthat is included in an explosive exhaust gas by charging the explosive exhaust gas with an indirect charging method of charging through ions that are injected from the outside.

Electrostatic precipitation device for removing particles in explosive gases

A vehicle air purifying apparatus is provided. The vehicle air purifying apparatus includes: a charger configured to discharge positive (+) ions or negative (&#x2212;) ions to charge particles included in harmful gas; a removable collecting electrode configured to have positive (+) or negative (&#x2212;) polarity to allow the particles charged by the charger to be attached thereto; and a filter configured to filter harmful gas and have positive (+) or negative (&#x2212;) polarity, and the filter is formed in a tubular shape having an empty space therein and the removable collecting electrode is inserted into the filter.
