Suspended matter removing instrument for diesel engine tail gas treatment liquid

Technical Field

The utility model relates to a technical field is got rid of to the suspended solid, specifically is an appearance is got rid of to diesel engine tail gas treatment liquid suspended solid.

Background

With the increasing automobile ownership in China, the harm of nitrogen oxide and particulate matters discharged by automobiles to human health and atmospheric environment has attracted high attention. The nitrogen oxides emitted by internal combustion engines of automobiles are mostly nitrogen monoxide (NO) and a small amount of nitrogen dioxide (NO), generally expressed as Nitrogen Oxide (NO). NO is a colorless gas, not itself toxic, but is slowly oxidized to NO in the atmosphere. NO2 is brown gas, has strong pungent taste, and can be inhaled into human body to combine with water to form nitric acid, which can cause cough, asthma, emphysema and cardiac injury. NO is one of the major factors in the formation of photochemical smog containing toxic ozone near the ground. It is reported that countries around the world are engaged in research for reducing these two emissions, and for our country, the "national V" emission standard that has been implemented means that more advanced technology must be adopted for the emission of automobile exhaust. A large number of experimental researches show that the Selective Catalytic Reduction (SCR) technology is the most suitable 'national V' emission solution for diesel vehicles, and the technology has to treat NO in tail gas by using urea solution, so that the vehicle urea solution becomes a necessary product of the 'national V' emission solution. The urea SCR technology is characterized in that a certain amount of urea aqueous solution is sprayed into an exhaust pipe, urea is subjected to evaporation, pyrolysis and hydrolysis to obtain a reducing agent NH, and the NH can selectively reduce NO into N under the action of a catalyst, so that the aim of reducing NO emission is fulfilled. If the diesel engine is not loaded with tail gas treatment liquid or with treatment liquid with low purity and poor quality, the engine of the vehicle can be automatically decelerated. Meanwhile, the diesel engine tail gas treatment liquid with poor quality can pollute the catalyst in the SCR catalytic reaction tank, thereby causing serious consequences.
