1. The system has simple structure, compact layout, smooth process and small investment. Since the system does not have an electrostatic precipitator or a large bag filter, it saves a lot of investment and land occupation. However, considering that the extremely small amount of dust contained in the circulating wind has some wear on the fan impeller, the medium speed is adopted in the fan selection. The wear-resistant fan ensures the service life of the fan. 2. The system adopts negative pressure and closed circulation without secondary pollution. The system exhausts into the fine ash warehouse of the finished product, and uses the filter of the top bag filter to avoid the pollution of the environment of the ring ramming machine and ensure that it meets the emission standards of the national first-class area. At the same time, the closed ash circulation in the conveying pipeline is not affected by meteorological conditions, and the moisture absorption is small and does not condense, which can greatly reduce the influence of air humidity on the sorting efficiency. 3. The system has good sealing performance and no leakage, which ensures the efficiency of system sorting. Since the system is a negative pressure sorting system, in addition to the system piping and equipment connections to be sealed, the vortex separator and cyclone separator discharge are very important, and the gas lock is not good, which will seriously affect the system sorting efficiency. To this end, the system uses the company's special lock gas unloading device, which consists of the sampling door and the gas breaker of the electric crusher manufacturer, which can effectively isolate the airflow between the negative pressure of the sorting system and the positive pressure inside the warehouse. The string can ensure that the sorting system is not affected by the air pressure in the ash silo, and the ash is smoothly discharged into the ash silo, and the system sampling is simple, convenient and fast. Second, the fly ash grinding sub-selection system consists of sandstone production line equipment: for roller crusher , dryer equipment, milling equipment, roller crusher, magnetic separation equipment are using innovative technology to make sand The production efficiency of crushing is improved step by step. Red Star insists on innovation, continuous research and development, innovative skills, and hopes to deliver fresh blood to the entire mad industry, bringing more vitality. The fly ash sorting system consists of a vortex separator, a cyclone separator, a high-pressure centrifugal fan, a variable frequency speed control feeder, a main air duct, and a return air duct. Third, the working principle of the fly ash grinding subdivision system The power source of the system is a high-pressure centrifugal fan. Under the negative pressure of the system, the fly ash is uniformly sucked into the pipeline by the negative pressure through the speed-adjusting feeder (the original ash in the original ash warehouse), and is fully mixed with the air in the pipeline. After entering the first-stage separation equipment------------------------------------------------------------------------------ It is captured by the wall surface or collided with the reflective screen, and is discharged by its own gravity; the fine particles are sucked away by the negative pressure of the eddy current zone, and are discharged through the volutes on both sides, thereby achieving separation of the coarse and fine particles. In fact, due to the aggregation of the particles and the entrainment of the large particles, some fine ash is always mixed into the coarse ash. In order to reduce the content of fine ash in the coarse ash, a secondary air inlet is arranged at the bottom of the vortex separator, that is, the position where the coarse ash is discharged, and the large-mass particles can be discharged through the air curtain, and the small-quality particles are blown back by the air curtain. The volute is discharged inside, thereby improving the efficiency of system sorting. At the same time, the fineness of the finished ash can be adjusted by adjusting the strength of the secondary air curtain to meet the requirements of different users. The fine ash discharged through the volute enters the second-stage separation equipment with the airflow----the cyclone separator (generally arranged on the top of the fine ash tank) to achieve the separation of the gas ash, and the ultra-fine dust remaining in the exhaust gas passes through the high pressure. The centrifugal fan (generally placed at zero meters next to the ash storage) is re-mixed with the material at the feed station for the next cycle.
