Abstract
This paper focuses on the design of heating in metallurgical plant mines. Through the analysis of the specific requirements of metallurgical plant mines, based on the characteristics of metallurgical plant mines, this paper discusses the design of effective and economical heating system.
1 Introduction
The metallurgical industry needs mining to create raw materials, and the mining process often involves a lot of underground work in shallow coal seams or other place. With the increasing depth and intensity of mining, temperature and humidity will gradually increase, so effective and economical heating system is needed to ensure the normal production of the mine and the safety of underground working staff.
2 Requirements of heating design for metallurgical plant mines
2.1 Thermal insulation
The selection of thermal insulation material of the heating system should be able to adapt to the environment of the mining industry, and the thermal insulation performance should be good. This kind of material should also be pollution-free, harmless and fireproof, and its resistance to various acids, alkalis and chemically corrosive materials should be higher.
2.2 Safety of air supply system
The air supply system of the heating system should have strong air tightness and reliable safety protection measures. It is necessary to eliminate the potential safety hazards caused by wind pressure, cooling rate, noise and vibration.
2.3 Energy saving
The heating system of metallurgical plant mines should use clean energy, and the operating temperature should be adjustable to achieve energy saving.
2.4 Easy maintenance
The heating system of metallurgical plant mines should be easy to maintain, and timely cleaning should be done to prevent the system from blocking due to accumulated dust and other impurities.
3 Design of heating system
3.1 Design of heating source
3.1.1 Heating source selection
The main source of heating for the heating system of metallurgical plant mines should be electric heaters, because electric heating is energy-saving, pollution-free and safe. It can be used flexibly and accurately at any time according to the requirements of different occasions.
3.1.2 Temperature distribution
The temperature shoul
