As my country's main energy source and important raw material, coal resources are very important basic energy sources. During the production process of coal, a large number of coal mines will be produced. These coal mines differ greatly in their properties and availability according to different varieties and formation mechanisms. With the rapid development of industrial technology, the output of coal mines has increased significantly. Under the influence of the market situation, the comprehensive utilization of coal mines has become an urgent problem to be solved.
Because coal mines have fine particle size, high water content, low calorific value, high viscosity, and some have certain fluidity, the stacking, storage and transportation of coal mines are very difficult. If it is not handled properly, it will not only cause a high waste of coal resources, but also cause serious environmental pollution. How to reduce the water content of coal mines, so that coal mines can be reused, and finally meet the requirements of the use of electric coal, has always been an urgent problem in the coal industry. And with the requirements of environmental protection policies, traditional treatment technologies have fallen behind, and thermal drying methods are no longer used to treat coal mines in many places. Therefore, the requirements for coal mine dehydration equipment are more stringent, and the upgrading of the dehydration process is also indispensable.
Combining the policy requirements and the characteristics of coal mines, "Techase CS type special coal & mining super high pressure filter press" does not need to be dried and dehydrated thoroughly. The coal cake has a moisture content of 12% to 17%, which meets the coal requirements of power plants. The processed coal briquettes can be directly used for power plant energy fuel/blending power generation, civil fuels, coal sales and chemical raw materials/additives, etc., thoroughly realizing the secondary utilization of coal mine resources, and turning coal mines into “gold”.
Technical advantages
1 .The coal mine is completely dehydrated, with a moisture content of 12%~17%
The coal mine has strong water holding capacity and high water content, and its shape is extremely unstable. To realize the comprehensive utilization of coal mine, it must first be dehydrated thoroughly. "Techase CS type special coal & mining super high pressure filter press" has high pressure, short working cycle and more thorough dehydration. In the face of a large amount of coal mine, it can also be treated efficiently. The coal cake has a moisture content of 12% to 17%, which meets the coal requirements of power plants and realizes the resource utilization of coal mine.
2. No need for heat source, low carbon and environmental protection, low investment cost
Based on the requirements of environmental protection policies, many coal washing plants no longer allow the use of thermal drying to treat coal mines. The technology adopted by Techase does not require a heat source, and only relies on mechanical pressing to quickly achieve coal mine dehydration, instead of the traditional pressing + thermal drying mode, without adding chemicals and drying equipment, low carbon and environmental protection, no environmental protection pressure, and low investment cost.
3. Low operating cost, significant economic benefits of coal mine
The coal mine produced in the coal production process is huge, and according to the constraints of the site environment, how to realize the resource utilization of the coal mine under the condition of low-cost operation is also a matter of great importance. This equipment has a large processing capacity, and the operating cost per ton is about 5 yuan, and the value-added value of coal mine is 50-200 yuan, and the value-added economic benefits of coal mine are significant.
4. Steel frame, high strength, stable operation
Due to the high water content of coal mines, the impact of water volume is large, which requires the dehydration equipment to have the characteristics of high structural strength. The plate frame of Techase filter press adopts a patented structure, and the service life of the steel plate frame is more than 8 years, which is stronger than the high-pressure diaphragm material. Hydraulic pressing, high-pressure operation is more stable and safer.
5. Cloud data management, high degree of automation
Coal mining sites usually have heavy tasks and high intensity, and the deployment of personnel needs to be reasonably controlled. At this time, a highly intelligent and fully automatic dehydration equipment is necessary. Techase can realize continuous operation and maintenance services of equipment through cloud data management, Internet of Things control, and simple digital panel operation, reducing on-site labor costs.
