Abstract
The invention discloses a waste gas cleaning device used for a diesel engine. The cleaning device comprises a heat pipe, a shell, an ammonia water spraying electromagnetic valve, a particulate filter, an oxidation catalyst, a dust purge valve, a dust blow off valve, a vehicle speed sensor, a restrictor sensor, a carbon monoxide sensor, a carbon-hydrogen sensor, a nitrogen-oxygen sensor and a controller, wherein the heat pipe is connected with the exhaust pipe outlet of the diesel engine; and the shell is connected with the heat pipe, and the ammonia water spraying electromagnetic valve is arranged on the end part of the shell and communicated with the inside of the heat pipe. In the waste gas cleaning device used for the diesel engine, a thermal insulation layer is adopted to keep the exhaust gas temperature, so that most of carbon monoxide and hydrocarbon are converted into carbon dioxide and water; the particulate filter is used for decreasing the solid particulate in the exhausted gas, and carbon monoxide and hydrocarbon are further converted to pollution-free gas by using the oxidation catalyst; and the ammonia water spraying electromagnetic valve is used for spraying the ammonia water under the action of the controller to reduce oxynitride so that oxynitride is changed into the pollution-free gas.
