Engine emission reduction device for monitoring NOx concentration in real time and adjusting oxyhydrogen amount

Abstract

The invention discloses an engine emission reduction device for monitoring NOx concentration in real time and adjusting oxyhydrogen amount. The device comprises a columnar shell, a cavity is formed in the columnar shell, asbestos fiber felt is arranged in the cavity, positioning holes which are distributed at equal intervals are formed in the outer wall of the columnar shell, refrigeration sheets are fixed to the inner walls of the positioning holes, a metal shell is fixed to the outer wall of the columnar shell, a damping layer is connected to the inner wall of the columnar shell in a sleeved mode, a gasket is bonded to the inner wall of the damping layer, a columnar catalyst is fixedly connected to the interior of the gasket in a sleeved mode, a honeycomb-shaped ceramic carrier is arranged in the columnar shell, and a fixed circular plate is connected to one end of the columnar shell in a threaded mode. According to the device, the asbestos fiber felt is arranged in the columnar shell, heat loss can be effectively prevented, internal temperature rising can be accelerated, the gas reaction rate can be increased, and when the temperature is too high in the reaction process, a switch of the refrigeration sheet is turned on, the interior of the columnar shell is cooled, and the internal temperature can be controlled within a proper range.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine emission reduction device for real-time monitoring of NOx concentration for adjusting the amount of hydrogen and oxygen. Background technique [0002] The engine is an energy conversion mechanism that converts the heat energy generated by fuel combustion into mechanical energy. It mixes air and fuel in proportion and atomizes a combustible mixture into the cylinder, and then compresses the combustible mixture entering the cylinder, causing the combustible mixture to ignite, burn, and expand. Generate high pressure to push the piston to do work, and finally discharge the exhaust gas after combustion. However, due to insufficient combustion of fuel, the exhaust gas emitted by the vehicle will contain harmful gases such as CO, HC and NOx. Therefore, the exhaust gas of the vehicle needs to be treated before being discharged. However, most of the traditional emission reducti...

Problems solved by technology

However, due to insufficient combustion of fuel, the exhaust gas emitted by the vehicle will contain CO, HC and NOx harmful gases. Therefore, the exhaust gas of the vehicle needs to be treated before being discharged. However, most of the traditional emission reduction devices have an integrated structure. When the internal When there is a lot of dust, it will interfere with the exhaust gas treatment, and because the exhaust gas temperature is too high, when the emission reduction device works for a long time, its temperature will gradually rise, so there will be a safety hazard of spontaneous combustion
