Intelligent smoke exhaust improvement device

Abstract

The invention provides an intelligent smoke exhausting improvement device. The intelligent smoke exhausting improvement device comprises a body. A connecting pipe is arranged at one end of the body , and an exhaust outlet is formed in the other end of the body; a bypass device is connected between the body and an engine through a connecting bent pipe; a microcomputer automatic control device can be used for full-automatic control, with the set value of the backpressure pressure in the body as a benchmark; when a ceramic filter core blocked the black smoke particles and the backpressure rises, the microcomputer automatic control device can control the bypass device to open a bypass valve, most exhaust gas can be discharged and part of the exhaust gas can also enter a smoke filter device, thus the wind pressure is lowered and the velocity of flow is decreased, the burning time of the black smoke particles on the ceramic filter core is prolonged, the burning efficiency of the black smoke particles on the ceramic filter core is improved and the automatic regeneration function is achieved; and when the backpressure of the device reaches the set value, the microcomputer automatic control device can control the bypass device to restore to the normal air inlet condition, the black smoke particles on a flow channel can be captured and burnt once again at the soaking temperature of the ceramic filter core , and thus automatic regeneration is achieved.

Description

technical field [0001] The invention relates to an intelligent smoke exhaust improvement device which can improve environmental hazards such as black smoke or poisonous smell of exhaust gas discharged from a diesel engine, and can effectively reduce the noise when exhaust gas is discharged. tools or similar constructs. Background technique [0002] Since 1892, German engineer Rudolph Diesel (Rudolph Diesel) invented a new type of diesel engine (Diesel Engine), which changed the application market of previous engines, because diesel engines can generate higher torque at low and medium speeds than previous engines Therefore, it has the obvious fuel-saving effect and the practicability of low carbon dioxide emissions. However, the diesel engine can produce high-efficiency engine power, but it also emits relatively more polluting exhaust gas. The main substance of the exhaust gas is nitrogen oxides (NOx) and ultrafine suspended particles (PM2.5), which are quite harmful and thr...

Problems solved by technology

[0003] Therefore, in the 1990s, Italian Fiat created a High Pressure Common Rail (High Pressure Common Rail) diesel engine, using electronic control means to precisely control the amount of diesel fuel entering the cylinder and the fuel supply time, because the pressure in the fuel supply pipe is higher, In turn, the effect of fuel atomization is improved, so that the fuel burns in the engine fuel chamber more completely and cleaner, and the noise and vibration are also greatly reduced, which has become the standard for the development and design of subsequent diesel engines. At present, diesel engines are less environmentally friendly than previous designs. Improvement, but its effect still cannot meet the current environmental protection standards. Therefore, diesel engines often need to be additionally equipped with expensive exhaust gas recirculation systems, carbon particulate filters and diesel emission catalytic reduction devices to effectively improve their polluting exhaust emissions.
