Tail gas treating device of internal combustion engine

Abstract

The invention discloses a tail gas treating device of an internal combustion engine, wherein a cylinder body is divided by a netlike clapboard into more than two filtration chambers; activated carbon is arranged on the clapboard; one end of a tail gas conduit is connected with a tail gas discharge port of the internal combustion engine; the other end of the tail gas conduit is accessed to the first filtration chamber; a heat dissipation pipe comes out from the last filtration chamber; the other end of the heat dissipation pipe is accessed to the first filtration chamber; in this way, a circulation line of a water solution is formed; and an exhaust port is also arranged on the last filtration chamber. Multiple activated carbon layers are arranged in the cylinder body disclosed by the invention, so that harmful substances in tail gas can be effectively adsorbed; the circulation line of the water solution is formed by the tail gas conduit and the heat dissipation pipe; and therefore, not only is the solubility of substances in the tail gas improved, but also the temperature of the tail gas is greatly lowered.

Description

technical field [0001] The invention relates to a tail gas purification treatment device, in particular to an internal combustion engine tail gas treatment device. Background technique [0002] With the development of industrialization and the improvement of people's living standards, the number of internal combustion engine vehicles in my country has increased year by year, and has exceeded 100 million. In addition, various types of internal combustion engines are used, accompanied by pollution caused by exhaust emissions. . The exhaust of internal combustion engines contains a large amount of harmful substances, such as carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide and incompletely burned carbon particles, which bring serious pollution to the environment. Therefore, the treatment of exhaust gas has become an urgent problem to be solved. Among the existing ones, people have been devoting themselves to the research on the treatment of internal combustion eng...

Problems solved by technology

Among the existing ones, people have been devoting themselves to the research on the treatment of internal combustion engine exhaust, such as the Chinese utility model patent whose publication number is CN2426525Y, which includes an exhaust duct, a washing tank, a recovery tank and a settling tank placed under the washing tank and the recovery tank, washing Both the tank and the recovery tank are equipped with an aqueous solution of chemical substances. The port of the exhaust gas conduit is equipped with a shower-shaped mesh plate and immersed in the aqueous solution of chemical substances in the washing tank. The exhaust gas passes through the cleaning tank and the recovery tank respectively along the exhaust gas conduit. The exhaust gas is discharged from the air outlet, and the exhaust gas can be washed by the chemical substance aqueous solution, which can precipitate and wash the particulate matter and filter out harmful substances. A certain range of chemical substance aqueous solution contacts and reacts, which cannot effectively clean the harmful substances in the exhaust gas; and after a period of reaction, the chemical substance aqueous solution is saturated, and the purification effect is even worse; in addition, with the continuous inflow of high-temperature exhaust gas, The temperature of the aqueous solution of chemical substances in the cylinder gradually increases, and the temperature of the discharged gas is also very high, which cannot play a role in cooling the exhaust gas
