Problems solved by technology

[0003] With the increasingly stringent emission regulations, the control of pollutants emitted by mining explosion-proof diesel engines focuses on the control of CO, HC and PM. However, the current mining explosion-proof diesel engines on the market mostly use mechanical pumps without any exhaust gas treatment devices. Cannot effectively solve the emission problems of CO, HC and PM

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with specific embodiments.

[0018] A particle collection and regeneration system for mine explosion-proof diesel engine, its structure is as Figure 1-3 As shown, it includes a trap and a regeneration device. The trap is used to reduce the emissions of CO, HC and PM in the exhaust system of the diesel engine. The regeneration device is to remove the PM inside the filter element of the trap.

[0019] The trap includes DOC2 and DPF3. DOC2 refers to an oxidation-type catalytic converter, which is installed on the exhaust manifold 7 of the mine explosion-proof diesel engine 1. Through the oxidation reaction, the CO and HC in the engine exhaust are converted into harmless water and water. Carbon dioxide; DPF3 refers to a diesel particulate filter. Its inlet end is fixedly connected to the DOC through a clamp 9 and its outlet end is connected to the exhaust pipe 8. The exhaust gas is filtered through a...

Abstract

The invention discloses a particle collection and regeneration system for a mine-used explosion-proof diesel engine, comprising a trap installed at the exhaust end of the explosion-proof diesel engine for processing the exhaust gas of the diesel engine, and a trap installed on the ground for regenerating the trap The regeneration device, the trap includes a DOC that is installed on the exhaust manifold of the mine explosion-proof diesel engine to convert CO and HC in the engine exhaust into harmless water and carbon dioxide through an oxidation reaction, and is equipped with a filter element inside for DPF for filtering exhaust gas and reducing PM content in exhaust gas. The DPF is fixedly connected to the exhaust end of the DOC through a clamp, and the outlet end of the DPF is connected to the exhaust pipe. The invention can safely and effectively realize the particle trapping work of the exhaust gas of the explosion-proof diesel engine, and can effectively reduce the content of CO, HC and PM in the exhaust pollutants.

Description

Technical field [0001] The invention relates to a particle capture and regeneration technology, belonging to the technical field of mine explosion-proof diesel engine emission. Background technique [0002] Explosion-proof diesel engines are mainly used in explosive places such as underground coal mines to provide power for underground transportation equipment. Explosion-proof diesel engines will produce a large amount of harmful substances such as carbon monoxide (CO), hydrocarbons (HC), particulate matter (PM) and so on. The pollutants emitted by its tail gas cause great harm to the miners working in the mine. Treat exhaust gas from mine explosion-proof diesel engines. [0003] As emission regulations become more and more stringent, the control of pollutants emitted by explosion-proof diesel engines for mines is focused on the control of CO, HC and PM. However, explosion-proof diesel engines for mines on the current market mostly use mechanical pumps and do not install any exhau...
