2022-08-09

The tail gas denitration device (SCR selective catalytic reduction system) of gas generator unit is a device that converts NOx into harmless nitrogen (N2) and water (H2O) under the action of catalyst. It is a special integrated denitration system for distributed energy. It has the following advantages and characteristics:

1. fast response

2. applicable to low, medium and high temperature denitration

3. mature and reliable technology, high denitration efficiency and reduction of ammonia escape

4. the ammonia injection is uniform, the resistance is small, the ammonia consumption is small, and the operation cost is relatively low

For ammonia escape control, GRVNES environmental protection adopts internationally advanced system control equipment and technology to form an accurate reductant dosage control system, which optimizes the reductant dosage to a large extent, thus successfully controlling ammonia escape.

For the special design of local environmental adaptability, we can carry out targeted design according to different local climate and environment. Not only the electrical components are industrial standard components, but also the control system has been treated accordingly. Therefore, the environmental adaptability of the purification device is very strong. The temperature and humidity of the project site will not affect the equipment, and the device can operate for a long time.

For the special design of urea characteristics and concentration selection, compared with liquid ammonia and ammonia water, urea is a non-toxic, harmless and non hazardous chemical, which has obvious advantages in safety, and users have no risks in the process of use and storage. When selecting the concentration of urea aqueous solution, the temperature of its condensation point (crystallization point) at different concentrations should be considered. When the urea solution is at a certain concentration, its condensation point will be in a lower temperature range, while under other concentrations, the condensation point temperature will increase.
