Introduction
The new dry process cement production technology is based on the suspension preheating and pre-decomposition technology, which uses the existing technologies in thermal engineering, powder engineering, fluid mechanics, etc.
The comprehensive technology of cement production is based on modern scientific theories and technologies, and adopts computer and network information technology. The complete set of equipment consists of relatively independent
The independent process system equipment mainly includes raw material crushing and homogenization, raw material preparation, fuel preparation, cement kiln co-processing, clinker burning, cement
Preparation, dust removal, desulfurization, denitrification, process control, packaging and other system equipment.
At present, my country's cement equipment and technology have reached the international advanced level, but the complete set of equipment based on system solutions is facing
With the expansion of the export of domestic cement complete equipment and the scale of engineering general contracting, the system of complete equipment is in urgent need of standardization and support.
The demand for systematic standards is also gradually increasing. The purpose of formulating the standards for new dry process cement complete equipment is to improve the user-oriented cement complete equipment
The standard system provides technical support for the high-quality development of the cement industry and better guides the industry to develop in the direction of green, low-carbon and intelligent manufacturing.
At the same time, it supports the export of complete sets of cement equipment in my country.
The equipment involved in this document is used to treat the flue gas (waste gas) containing nitrogen oxides during the cement clinker burning process to achieve the removal of nitrogen oxides.
This document is formulated to provide technical support for the green, low-carbon and high-quality development of the cement industry.
