Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part

1.Structure and drafting rules for standardization documents" Drafting is required. This document is part 5 of GB/T 35150 "Technical requirements for complete sets of equipment for the production of new dry process cement". GB/T 35150 has been issued The following parts were published. Part

1 Scope

GB/T 35150.5-2024 is the dedusting part of the Chinese standard for complete dry process cement production equipment. Cement is the largest single source of industrial particulate in China, and the dedusting system is what stands between the kiln, mill and cooler and the emission limit; it is also a system that has to work continuously in high temperature, high dust-load gas with acid dewpoint and abrasive material, and that fails in ways, bag rupture, poor pulse cleaning, hopper bridging, that show up first as an emission excursion. The standard sets the classification and composition of the dedusting systems used across the plant, then the technical requirements: the performance in outlet dust concentration, collection efficiency and pressure drop, the design and construction of the filter, its media, cages, cleaning system and hoppers, the gas conditioning and temperature protection, the fans and ductwork, the ash handling, the instrumentation and control including the leak detection, and the safety, energy consumption and reliability requirements. It then gives the test methods and inspection rules. It takes effect on 1 June 2025.

This document specifies the classification, composition, technical requirements, safety and environmental protection, installation and maintenance of the dust removal system in the new dry process cement production equipment. Acceptance and commissioning, performance testing and delivery documents. This document applies to the design, manufacture and acceptance of organized emission dust removal systems in new dry process cement production equipment.

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 adopts modern scientific theories and technologies, and uses computers 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 shipping 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 domestic cement equipment exports and engineering general contracting, the systematic support of complete sets of equipment is urgently needed. The demand for standards is also gradually increasing. The purpose of formulating the standards for new dry process cement complete sets of equipment is to improve the user-oriented cement complete sets of equipment standards. The system provides technical support for the high-quality development of the cement industry, better guides the industry to develop in the direction of green, low-carbon, and intelligent manufacturing, and supports Support the export of complete sets of cement equipment in my country. This document is used to remove solid particles from dusty gases during cement production to ensure that the emission standards for atmospheric pollutants are met. The formulation provides technical support for the green, low-carbon and high-quality development of the cement industry, and coordinates with other series of standards.
