Description

Ammonium carbonate powder manufacturing equipment for replacing urea water}

The present invention relates to an apparatus for producing ammonium carbonate powder for replacing urea water, and more particularly, by converting ammonium carbonate in liquid form into powder form to reduce volume compared to liquid form while producing high concentration of ammonium carbonate. Urea manufactured and used as a catalyst for decomposing exhaust gas generated during the operation of a diesel driving engine, especially in large ships, to provide a high concentration of powdered ammonium carbonate in a relatively small volume compared to the number of urea used as a catalyst conventionally It relates to an apparatus for producing ammonium carbonate powder for replacing water.

In general, urea water is an aqueous solution of urea used to reduce the amount of air pollutant emissions by reducing nitrogen oxides to nitrogen through selective catalytic reduction (SCR) in diesel engines. there is.

This number of urea is used in diesel-powered engines that use diesel (diesel) to prevent environmental pollution, and the consumption varies depending on the engine used. Replacement or replenishment is recommended.

In general, the number of elements as described above is interlocked in the electronic control device, and when the number of elements is insufficient, a signal is displayed on the instrument panel, and it is recommended that the engine is designed to not start without the number of elements. In Europe, it is recommended to use AUS32 with AdBlue, a certification mark of the German Automobile Manufacturers Association (VDA), for vehicles, and internationally, it is required to obtain a certification mark that satisfies ISO22241 (or DIN70070). Although there is a difference depending on the driving environment and vehicle performance of the vehicle, it is possible to drive about 7,000 kilometers by injecting approximately 10 liters.

In Korea, until 2013, Lotte Fine Chemical was the only producer of urea, a raw material for urea water, until the last. Production was completely stopped in 2014 due to issues such as competitiveness.

Meanwhile, ammonium carbonate is a salt, and the chemical formula is (NH4)2CO3. Commercial ammonium carbonate is not a compound, but another compound with a similar ammonia content, and is used as a blowing agent as a smelling salt because it readily decomposes into ammonia and carbon dioxide when heated.

In addition, ammonium carbonate dissolves well in water, but does not dissolve in ethanol and carbon disulfide.

Solids are decomposed at 58°C and aqueous solutions are decomposed into ammonia, water, and carbon dioxide at 70°C.

Ammonium carbonate solution having the above characteristics does not generate solid salt during combustion, and the decomposition temperature (100~150℃) is significantly lower than that of urea water (200~400℃), so the nitrogen oxide gas treatment efficiency is high. Therefore, it is attracting attention as a material to replace industrial urea water.

However, conventionally, since ammonium carbonate is stored in a solution state and used when necessary, a lot of space is required for storage, and since it is bulky and heavy, it is economical because it requires attention in the transport and storage process as well as additional costs. I had this low problem.

In particular, in devices using large diesel engines such as large ships, urea water or ammonium carbonate is also used in a large amount. It requires an area, and there is a problem in that the solution is not stabilized by vibrations and shocks generated during the movement of the ship.
