An exhaust gas purification device for a diesel engine, including a heat pipe, a housing, an ammonia water injection solenoid valve, a particle filter, an oxidation catalyst, a dust removal valve, a dust purge valve, a vehicle speed sensor, a throttle sensor, a carbon monoxide sensor, a hydrocarbon The gas sensor, the nitrogen oxygen gas sensor and the controller, the heat pipe are connected with the outlet of the exhaust pipe of the diesel engine, the shell is connected with the heat pipe, and the ammonia injection solenoid valve is arranged at the end of the shell and communicated with the inside of the heat pipe. In the exhaust gas purification device used for diesel engines, the present invention adopts a thermal insulation layer to maintain the exhaust gas temperature, converts more carbon monoxide and hydrocarbons into carbon dioxide and water, and adopts a particle filter to reduce solid particles in the exhaust gas, and oxidizes and catalyzes The device can further convert carbon monoxide and hydrocarbons into non-polluting gases. The ammonia water injection solenoid valve sprays ammonia water under the action of the controller to reduce nitrogen oxides and make them into non-polluting gases.
Description
Technical field: [0001] The invention relates to the mechanical field, in particular to a diesel engine, in particular to an exhaust gas purification device for a diesel engine. Background technique: [0002] In the prior art, the exhaust gas emitted by diesel engines, especially heavy-duty diesel engines, seriously pollutes the environment. At present, the National 4 (Euro 4) standards have made new regulations on the exhaust emissions of automobile diesel engines and put forward higher requirements. Therefore, the use of reasonable exhaust gas purification devices can reduce the exhaust emissions of automobile diesel engines, especially the reduction of exhaust emissions The content of particulate matter and hydrocarbons and carbon oxides in the air. Invention content: [0003] The object of the present invention is to provide a kind of exhaust gas purification device for diesel engine, described this exhaust gas purification device for diesel engine will solve the cont...
