Mine on-demand ventilation thermal load control system and method

Abstract

The invention provides a mine on-demand ventilation thermal load control system. The system comprises a data acquisition terminal and a video input device, wherein the data acquisition terminal and the video input device acquire and upload real-time data in a mine; the data storage operation center server receives the data, analyzes the data in real time and issues an adjustment instruction to the execution unit; the waste heat recovery remote control unit and the electric heating remote control unit receive the adjustment instruction and implement the adjustment instruction; and the wireless communication systems among the devices are interconnected and intercommunicated to realize the connection among the internal devices to form a control system. The mine on-demand ventilation heat load control method is specifically implemented. The dynamic on-demand ventilation heat load of the mine is controlled under the high-altitude and high-cold conditions, so that the heat load of the mine is balanced, the energy utilization rate of the mine is increased, and the safety risk of mine production is reduced.

Description

technical field [0001] The invention relates to the technical field of mining, and more specifically, to a mine on-demand ventilation heat load control system and a method for applying the mine on-demand ventilation heat load control system. Background technique [0002] With the development of society, a large amount of resources are consumed, how to effectively use resources has become the focus of social attention. At present, there are tens of thousands of mines in our country, and most of them use underground mining. In order to ensure that the underground environment of underground mining meets the working requirements of personnel, it is necessary to establish a mine ventilation system and a mine temperature control system. Mine ventilation system and mine temperature control system consume a lot of energy every year. Therefore, it is an inevitable trend to install demand ventilation systems in mines. [0003] Ventilation management is an important part of the proc...

[0004] In the prior art, the utility model patent with the application number CN201821698193.2, Mine On-Demand Heating System, introduces a method of determining additional heat supply according to the amount of waste heat recovery and the preset heating plan to reduce energy waste The system does not consider the impact of complex and changeable mine environment, ventilation, production and other factors in high-altitude and cold areas, nor does it consider the need for dynamic and timely adjustment and control of heat loads, nor does it consider the implementation of control systems related to on-demand heating method

[0005] The utility model patent with the application number CN201620779415.8, a mine return air waste heat recovery system, introduces a mine return air waste heat reuse system, without considering the complex and changeable environment, ventilation and production of mines in high-altitude and cold areas and other factors, and did not consider the dynamic and timely adjustment and control of the heat load, nor did it consider the implementation method of the control system related to on-demand heating

[0006] The utility model patent with the application number CN201920200065.9, a mine exhaust waste heat extraction and utilization device, utility model patent, introduces a combination of heat pipe technology and heat pump technology to use the heat of mine exhaust air for secondary heating The wind device does not take into account the establishment of an integrated heat load control system for mines, the influence of complex and changeable mine environment, ventilation, production and other factors in high-altitude and cold areas, and does not consider the need for dynamic and timely adjustment of heat loads control, and does not consider the method of implementation of control systems related to heating on demand

[0007] Therefore, in the on-demand ventilation system in mines, especially in high-altitude and cold areas, the mine environment is changeable, and the temperature adjustment system of the mine is not adjusted according to the change of air volume and the change of the environment, so it will cause waste of energy, and, in special When high-intensity heating is urgently needed, the temperature adjustment system of the mine does not respond dynamically in time, which will cause freezing and increase the risk of potential safety hazards
