1.Structure and drafting rules for standardization documents" Drafting is required. This document is part 4 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 35150.4-2024 is Part 4 of the Chinese series on complete equipment for new dry process cement production, and covers the co-processing system that burns waste in the cement kiln. A cement kiln is an attractive destructor because it runs at over 1400 degrees with long residence times and an alkaline environment that captures acid gases, and the ash becomes part of the clinker rather than a residue to be landfilled; the risk is that the waste stream disturbs the kiln chemistry or the emissions, so the handling equipment matters as much as the kiln. The standard sets the system equipment composition and its performance indicators, then the technical requirements for the basic system, the storage equipment, the pre-treatment equipment, the conveying equipment, the dosing equipment, the environmental protection equipment, the fire fighting equipment and the electrical and process control equipment, followed by the safety and environmental protection provisions and the test requirements and methods. It took effect on 23 August 2024.

This document specifies the system equipment composition and performance indicators of the cement kiln coordinated disposal system in the new dry process cement production complete set of equipment, technology Requirements, safety and environmental protection, installation acceptance, commissioning and performance testing and delivery documents. This document applies to hazardous waste, general industrial solid waste, domestic waste (including solid waste generated during the disposal of domestic waste), Construction waste, urban sewage treatment sludge, contaminated soil, emergency waste, agricultural and forestry solid waste, etc. are used in the new dry process cement production line. Design, manufacture, installation, commissioning and acceptance of disposal systems.

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. The new dry cement kiln co-treatment of solid waste has many technical advantages such as high incineration temperature, stable incineration state, and alkaline environment. The document is used to standardize the technical requirements of cement kiln collaborative disposal system process design, equipment acceptance, performance testing, etc., and promote the coordinated disposal of cement kilns. Under the premise of not affecting the quality of cement products and stable production, the solid waste can be harmlessly disposed of or recycled. Other series of standards are coordinated with each other. GB/T 35150 is planned to consist of seven parts. Part
