Internal combustion engine waste gas purifier

Abstract

This is a waste gas purifier of combustion engine which consists of wet collector, pipes, booster fan, controlled one-way valve and another controlled one-way valve connecting with the outside and control line. One end of the pipe is linked with the off-gas outlet, the exhaust flows through the one-way valve into the pressure fan and then discharges into the water in the purifier through another valve. The pipe in front of the valve is installed with a pneumatic sensor and a controlled one-way valve connecting with the outside. These valves and sensor and controllers are all connected by the control line. Because the cleaner is installed with the controlled one-way valve and pressure device, it can force dust out and naturally flame out according to the working conditions in the combustion engine, besides, it can well prevent water from recharge when there is a flameout, so it can satisfy more the technological and market demand.

Description

technical field [0001] The invention relates to an exhaust gas purifier of an internal combustion engine, in particular to an exhaust gas purifier of an internal combustion engine comprising a wet flue gas purification device. Background technique [0002] When the internal combustion engine is working, it must discharge exhaust gas, which contains various harmful gases such as smoke, sulfur dioxide, nitrogen monoxide, etc., especially when the fuel is not fully burned, it will often emit black smoke, such as when the vehicle is just started. Billowing black smoke is often emitted, which is incompletely burned fuel coke solid particles, and exhaust gas is the chief culprit of environmental pollution. For this reason, people have adopted a variety of methods to purify the harmful substances in the exhaust gas discharged by internal combustion engines, such as various wet flue gas purification devices, etc. The main principle is to introduce the exhaust gas into a container an...

Problems solved by technology

These schemes all focus on how to treat the exhaust gas, and have not done any special research on some characteristics of the exhaust gas emitted by the internal combustion engine, that is, the relationship between the exhaust gas exhaust condition of the internal combustion engine and the wet dust removal, such as the negative pressure of the exhaust gas, Since it takes a certain pressure to discharge the exhaust gas from the wet flue gas purifier, this has a certain impact on the start-up of the internal combustion engine. In addition, when the internal combustion engine is turned off, there will be negative pressure in the pipeline, which sometimes produces water in the wet flue gas purifier. Issues such as recharge
