Heated urea injection tube is an important component of selective catalytic reduction (SCR) system for diesel engines. Here is a detailed description of the product:
I. Product overview
The heated urea injection pipe is mainly used for the injection transportation of urea solution in the SCR tail gas post-treatment system, which can heat the urea aqueous solution to a certain temperature, so that it becomes ammonia, and then react with the nitrogen oxides (NOx) in the tail gas, converting it into harmless nitrogen and water. The pipeline has high heating efficiency, high pressure resistance, corrosion resistance and other properties, and is widely used in road and non-road SCR post-treatment systems used in cold areas.
Second, the working principle
The heating urea injection tube converts electrical energy into heat energy through a heating element, heating the urea aqueous solution to more than 180 ° C, thus decomposing it into ammonia gas. The ammonia then reacts chemically with NOx in the tail gas under the action of SCR catalyst to form nitrogen and water.
Third, product characteristics
Efficient heating: The heating tube quickly heats the urea solution to the desired temperature, increasing the efficiency of the SCR system.
Corrosion resistance and high temperature resistance: The heating pipe is made of high-quality materials and advanced production technology, with excellent corrosion resistance and high temperature resistance.
Energy saving and environmental protection: The heating element of the heating tube uses materials with high energy conversion efficiency, which can maximize energy utilization while reducing the impact on the environment.
Flexible arrangement: the thermal layer heating is circular heating, which can match various lengths and make various shapes of special-shaped pipelines, and has more advantages in pipeline layout.
