Power Plant Limestone Desulfurization Solution

2021-09-08 13:38:32 Micro Powder Technology

Project Background

Environmental protection is one of the main issues of human society in the 21st century. Thermal power plants and coal-fired boilers are large-scale industries with concentrated SO2 pollution. Limestone-gypsum flue gas desulfurization wet process (FGD) and boiler internal calcium injection technology are currently mature and widely used SO2 emission control technologies in the world. More than 90% of domestic thermal power plants use limestone-gypsum wet desulfurization.

Power Plant Limestone Desulfurization Solution

SBM Ultrafine Powder Tech has launched an overall solution for the desulfurization and powder production system of thermal power plants. From the preliminary raw material testing to the later installation and commissioning, acceptance and commissioning, SBM Ultrafine Powder Tech provides full guidance and equipment main and auxiliary machine production inspections, and has a professional Our technical service team will carry out post-system maintenance for you.

Project Flow

SBM Ultrafine Powder Tech has many years of professional experience in the research of non-metallic minerals such as limestone. It can help customers complete the grade test of the desulfurized limestone raw material minerals to determine a reasonable grinding plan; and can test the fineness and particle size distribution of the finished powder. The reaction activity thus determines the desulfurization efficiency. SBM Ultrafine Powder Tech starts from the reality of limestone powder preparation engineering to provide customers with technical support to improve the quality and output of limestone powder.

1. Raw Material Inspection

Most of the desulfurizing agents in the environmental protection desulfurization process of power plants are limestone powder. The quality, fineness, particle distribution, and reaction activity of limestone powder are the key factors affecting the desulfurization effect. The process will be limestone with a calcium content of more than 50% and a fineness of about 325 mesh. The powder is made into a slurry to filter out the SO2 in the coal-fired flue gas to meet the requirements of power environmental protection. The quality of limestone powder is the key to whether the desulfurization efficiency affects the power environmental protection standards.

2. Process Design

SBM Ultrafine Powder Tech has a technically reliable service team. After years of hard exploration, it has established a complete and effective service system. On the basis of surveying and planning the site for customers, it provides customers with detailed project design plans and reasonable The equipment selection plan, equipment list and project cost, design site basic drawings, and can design special processes and procedures according to the special requirements of customers. The team's expertise covers the entire process chain of limestone powder making.

3. Equipment Election

The environmentally friendly desulfurization limestone powder preparation system can operate for 300 days a year, effectively operating for 20 hours a day, and calculate the required single machine hourly output based on the amount of limestone powder required for environmentally friendly desulfurization in a year, and then select the mill model based on the single machine hourly output According to the hourly output of the mill and the output per ton, the ventilation volume of 2500~3000m3 is configured, and the model and specifications of the corresponding dust collector are selected from the calculated total ventilation volume. The fan for the system selects specifications and models according to the air volume, resistance and temperature of the system, and the size of the hot blast stove is designed according to the heat balance calculation results.

HGM Ultrafine Grinding Mill

1. High capacity and low energy consumption

The output is more than double that of the ball mill, and the energy consumption of the system is only 30% of that of the jet mill.

2. Any adjustment of fineness

The fineness of the product can be adjusted arbitrarily between 325 mesh and 2500 mesh.

3. Safer operation

There is no problem that the bearings and their seals are easily damaged, and there is no problem that the screws are easy to loosen and damage the machine; production is safer.

4. High level of environmental protection

Organize production in full accordance with national environmental protection standards and meet national environmental protection production requirements.

5. High processing accuracy

Digital control, high processing accuracy, some core components are accurate to a touch or even higher standards.

6. Supply of original parts

Provide customers with technical services and original parts supply services throughout the product life cycle.
