Manufacturing method and manufacturing system of urea solution for vehicle

Abstract

The invention discloses a manufacturing method and a manufacturing system of a urea solution for a vehicle. The manufacturing method comprises the following steps: S1, manufacture of high-purity water, S2, preparation of the urea solution for the vehicle, and S3, filtration and purification of the urea solution for the vehicle; in the manufacturing process, quality controlling and data monitoring are conducted in real time through a control unit and each data collecting sensor, and data are transmitted to a mobile terminal through a cloud platform. The manufacturing system comprises a control unit, the cloud platform and the mobile terminal, and further comprises a water supply unit and a feeding unit as well as a urea solution manufacturing unit and a filtration and purification unit; the control unit is used for control of the whole system, data collection, data analysis and automatic control. In conclusion, according to the manufacturing method and manufacturing system of the urea solution for the vehicle, which are disclosed by the invention, the urea solution for the vehicle, which has qualified urea solubility, can be automatically manufactured; the manual operation strength and frequency are reduced; the manufacture of the urea solution for the vehicle is automatically completed; the mobile terminal can be supervised and looked over in real time through the cloud platform.

Description

technical field [0001] The invention belongs to the technical field of urea solution for vehicles, and in particular relates to a method and system for manufacturing urea solution for vehicles. Background technique [0002] Urea water has the function of purifying NOx, and is widely used in the gas purification system of large diesel vehicles. Automotive urea, it is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. The scientific name of urea for vehicles is diesel engine exhaust treatment fluid. In China, it is commonly known as urea for vehicles, urea for vehicles, environmental protection urea for vehicles, and denitration agent for vehicles. The most commonly used urea for vehicles is vehicle urea. Urea for vehicles is used to reduce nitrogen oxides. It can be used as a reducing agent in the SCR (Selective Catalytic Reduction) system. It uses aqueous urea for vehicles to react with nitrogen oxides in the exhaust of diesel vehi...

Problems solved by technology

[0003] Traditional vehicle urea is prepared by mixing urea raw materials and deionized water in a certain proportion to make a urea solution, and then filling it after filtering and passing the inspection. The traditional inspection is sampling inspection, which is cumbersome and efficient. Low, and if there are unqualified indicators in the production process, it cannot be discovered in time; in addition, the current production equipment relies on manual feeding, which will cause unstable product quality, and the links between the various steps are not tight, the labor intensity of the workers is high, and the production efficiency is relatively high.
