Abstract

The invention belongs to an adding device using ammonium thiocyanate as vehicle a urea tracer agent, a method and the application. The adding device comprises a urea solution tank, a vehicle urea prilling tower and a vehicle urea packaging system. The urea solution tank is connected with a first segment of evaporation separator through a monitor of a first segment of evaporation heater. The segment of evaporation separator is connected with a second segment of evaporation heater through a U-type pipeline. The second segment of evaporation heater is connected with a second segment of evaporation separator which is connected with the vehicle urea prilling tower and the vehicle urea packaging system. A tracer agent adding opening is arranged in the U-type pipeline and is connected with a tracer agent stirring tank through a tracer agent flow control device. A tracer agent charging opening and a water charging opening are arranged in the top of the tracer agent stirring tank. The adding device, the method and the application are advantageous in that a production device is proper in design; the detection method is simple and precise; product sources can be traced; counterfeit and shoddy products are prevented from being passed; quality monitoring of vehicle urea production enterprises is facilitated; and rights and interests of consumers and production enterprises are maintained.

Description

technical field [0001] The invention belongs to the technical field of urea tracers for vehicles, and in particular relates to a device, method and application for adding ammonium thiocyanate as a urea tracer for vehicles. Background technique [0002] Urea solution for vehicles is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition is 32.5% high-purity urea and 67.5% deionized water. Since the environmental protection departments of various countries have proposed to further reduce the nitrogen oxide pollutants emitted by diesel engines. Commonly known as Euro IV standard in China. Engine manufacturers began to use SCR technology (Selective Catalytic Reduction Technology Selective Catalytic Reduction Technology) to meet the requirements of the environmental protection department. Urea solution for vehicles is a consumable that must be used in SCR technology. In Europe, this policy has been implemented since 2006....
