Beijing Minhaiyan Technology Co., Ltd. invested 3 million yuan in the environmental protection project of the original Dengdian Group Aluminum Alloy Co., Ltd., which will be officially launched at the end of July. After the completion of the project, the production line can produce 600 tons of micro-silica powder per month. It is reported that the reason why Minhaiyan Company can successfully contract this project is attributed to the three patented technologies developed by the company - the new technology of micro silicon powder purification and recycling, the double cylinder centrifugal frequency conversion electrostatic particle preprocessor and the micro silicon powder recycling process. The temperature regulation and tempering device.
Beijing Minhaiyan Technology Co., Ltd. is a technology-oriented enterprise integrating scientific research and development, environmental protection engineering, waste gas treatment and dust purification and recycling. Its main product is micro silicon powder. Since its establishment in 2008, the company has taken innovation as its own responsibility and successfully developed a number of patented technologies for independent intellectual property rights. In 2009, it developed a micro-silica powder purification technology and a dual-cylinder centrifugal variable-frequency electrostatic particle preprocessor for micro-silicon. The temperature regulation and tempering device in the powder recycling process has been officially approved by the State Intellectual Property Office. Currently, these three patents have been successfully applied to production.
The micro-silica powder purification technology effectively monitors and regulates the temperature and concentration of high-temperature dust flue gas through monitoring, control, purification, and recovery processes, avoiding the different conditions of raw materials, furnace conditions, and smelting processes at different stages in the smelting process. Large fluctuations in the amount of flue gas and smoke components ensure product quality, and at the same time, the separation of coarse particles in dust and dust and various metal oxide dusts can be achieved by centrifugal separation, gravity separation and electrical separation. The treatment increases the content of silica in the microsilica.
The double cylinder centrifugal frequency conversion electrostatic particle preprocessor is to place a plurality of discharge electrodes inside the large tube and the "U" type connecting tube, and one end of the connecting tube runs through the inside of the large tube, and the other end is inserted inside the small tube, the large tube and the small tube A connection port is provided at the connection of the cylinder. After entering the large cylinder and the small cylinder through the air inlet, the flue gas is rotated and separated inside, and the flue gas is separately enriched, regulated, centrifugally separated, and electrically separated. When the flue gas is in contact with the discharge electrode, the electrode is discharged. The generated electrostatic field separates the coarse particles in the flue gas from the various metal oxide dust impurities, increases the content of silica in the microsilica powder, and avoids the wear of impurities on the filter bag and the main fan, ensuring micro The quality of silicon powder processing.
The temperature regulating and tempering device applied in the micro silicon powder recycling process is mainly composed of a monitoring device and a wild air valve. The wild air valve is a three-way valve, wherein the two-way valve is respectively connected to other devices on the outside through the pipeline, and the other valve is open to communicate with the outside, so that outside air can enter the system through the valve. The monitoring device is composed of a monitor and a control device, and the control device is respectively connected with the wild air valve and the external main fan. The monitor consists of two parts, a temperature monitor and a concentration monitor. The temperature monitor and the concentration monitor are used to monitor the temperature and concentration of the flue gas. The invention can prevent large fluctuations in the amount of flue gas and smoke components due to different raw materials, different furnace conditions and different stages of the smelting process in the smelting process, and affect subsequent processing techniques and product quality.
The advent of these three technical patents has increased the content and activity of silica in microsilica powder, ensured the production of high-grade micro-silica powder, filled the gap in the domestic market, and broke the monopoly of foreign products. The new technology has been successfully applied in the company's production process. According to this technology, Beijing Minhaiyan 97, 98 high-purity micro-silica powder is becoming more and more popular. It is widely used in the Sailong and ceramic products, and exported to Europe and the United States. More than a dozen countries and regions.
