vertical grinding mill: environmental desulfurization plants good helper2015-05-05
Now SO2 emissions are quite high in the world. Thermal power plants are the most concentrated industries, and monitoring objects of the national environmental department focus. The national environmental protection departments gradually increase supervision; SO2 emissions must meet the national emission standards.
Limestone - gypsum wet flue gas desulfurization (FGD), is the world's most mature technology, the most widely used FGD technology, more than 90% of domestic thermal power plants are used in the process. vertical grinding mill processes limestone into 325 mesh fineness limestone powder and make into seriflux, then filter out coal-fired flue gas SO2, to meet the power requirements of environmental protection. Limestone powder prepared in respect of the desulfurization efficiency is the key to whether or not the impact of electricity environmental standards.
Vertical grinding mill milling system selection of raw materials limestone particle size of 0-30mm, the presence of limestone blocks heap raw material storage, and then by forklift raw shovel to four feed ports, arranged at each inlet of a feeder, by giving feeder will continuously be fed limestone blocks evenly on a large angle belt conveyors, conveying process via separator to remove metal objects, limestone blocks are belt conveyor to the vertical grinding mill after the front of the adjustment silo impurity, and then through an electromagnetic feeder evenly into the mill to. Mill closed wind circulation system vacuum system, limestone blocks in the mill was grinding roller and grinding ring rolling each other, once they reach the required fineness, they promptly elected from the moment the separator into the powder collector, then the output of finished powder.
Complete production line a total of eight powder collector exports of finished products, finished products exports four pulse dust collector, 12 finished products for export in parallel to an air conveying chute. The entire production line of finished powder imported unity within the air delivery chute, is transported to hoist the feed inlet, raised to the finished material tank. The upper tank equipped with facilities and warehouse roof ESP, the whole production line four pulse filter through the same exhaust pipe vented to the atmosphere, both inside and outside the workshop to ensure clean and green environment.
The vertical grinding mill production line is four independent production system, each mill production systems can work independently of each other produce. It is used throughout the production process automation control, fast, efficient and easy operation mode.
The entire production line is reasonable design simple, coherent process closely, equipment, compact layout, production of environmentally friendly low-carbon, energy-efficient operation, unmanned, modernization, automation, humane production environment.
