Automobile urea solution production device and method

Abstract

The invention discloses an automobile urea solution production device and method. The automobile urea solution production device comprises a stirring tank (6), a urea raw material bucket (9), a water inlet pipeline, a finished-product tank (12), a concentration sensor (5) and a solution valve (4), wherein the stirring tank (6) is provided with a urea raw material inlet, a water inlet and a solution outlet; the urea raw material bucket (9) is used for conveying urea to the stirring tank (6); the urea raw material bucket (9) is communicated with the urea raw material inlet through a urea pipeline; the water inlet pipeline is communicated with the water inlet; the finished-product tank (12) is used for storing a solution; the finished-product tank (12) is connected with the solution outlet through an output pipeline; and the concentration sensor (5) and the solution valve (4) are arranged on the output pipeline. According to the automobile urea solution production device disclosed by the invention, the concentration of the solution is detected through the concentration sensor; and when the concentration of the solution reaches a pre-set concentration, the solution is conveyed to the finished-product tank and the quality of the automobile urea solution is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of urea preparation, in particular to a vehicle urea solution production device and method. Background technique [0002] Vehicle urea solution, also known as vehicle urea, is a liquid used in SCR (Selective Catalyst Reduction, Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in vehicle exhaust. [0003] At present, the preparation of vehicle urea solution is mainly the operation of dissolving agricultural grade urea in pure water. Since agricultural grade urea contains a certain amount of impurities, it is necessary to remove impurities from vehicle urea solution. [0004] Because agricultural grade urea contains impurities that cannot be calculated, even if the mixing ratio of urea and water is controlled, it is impossible to obtain an accurate concentration of urea solution for vehicles. And then make vehicle urea solution concentration control bad, can't guarantee the quality...
