Clean coal mine solutions

Solve the coal mine energy saving dilemma

In coal mining, Huichuan HD9X series medium-voltage frequency converter products effectively reduce the impact on the power grid during the start-up process of high-power load by carrying out the soft start design of public auxiliary equipment such as compressors and air separation in the coal mine industry, as well as the conversion transformation of key equipment such as compressors, so as to avoid the grid side equipment tripping due to impact, resulting in production shutdown. Improve the reliability of frequency conversion operation of key equipment, ensure the uninterrupted operation of equipment, and avoid unplanned shutdown.

In the link of coal mine utilization, the “double tuning optimization” technical solution of Huichuan Technology combined with high-voltage inverter and dynamic adjustable fan has been successfully applied in the conversion transformation of axial-flow fan and induced draft fan of coal-fired units with adjustable blades. The combination of high-voltage inverter adjusting fan speed and blade Angle to meet the wind pressure or air volume required by the process can realize flexible adjustment of coal-fired units. Reduce the power plant coal consumption, reduce the plant electricity rate of 0.3~0.5%, the comprehensive power saving rate of more than 20%; Through the translation of the fan performance curve, a technology to keep the high efficiency of the fan is provided.

Green, efficient, intelligent mining equipment electrification solutions

It is a general trend for new energy mining cards to replace fuel mining cards, which has become the consensus of the industry.

Huichuan Technology brings electric loaders, electric mining cards, electric excavators and other models of electrification solutions to the coal mine industry. At present, Huichuan mining equipment electrification solutions market share of 70%, motor controller sales accounted for the first in China.

Huichuan Technology also showed the industry digital technology integration of the whole energy industry chain “scenery hydrogen storage” clean energy integrated solutions and products. Through the innovation path of “digitalization + automation + energy”, intelligent and green energy will be deeply integrated to help the high-quality development of the coal industry. Green and low-carbon development is the direction of energy transformation, and coal is the “ballast stone” of energy security and stable supply, and intelligent coal mine is the basic project of high-quality development.

In the future, Huichuan Technology and its subsidiary Zhiding Technology will continue to focus on the needs of “digitalization, intelligent transformation and efficient and safe operation of the coal industry”, accelerate the clean and efficient development and utilization of coal and intelligent development of mines, and actively explore a new path for the development of the coal industry’s “dual carbon” strategy, injecting strong impetus into the high-quality development of the coal industry.
