Not long ago, the Sichuan Coal Group Tatsu Corporation coal preparation plant successfully transformed the slime water treatment system to solve the blockage of slime, the internal circulation of water "run, leak" problem, reducing the impact of coal washing time, and achieved good economy Benefits and ecological benefits. The heavy medium coal preparation plant has put into operation since the coal washing plant production capacity continues to increase, slime water also will increase, the original slime water treatment system can not fully meet the current production needs, especially the lack of storage space concentrator , Often appear blocked slime and internal circulating water "run, leak" phenomenon. In order to solve these problems, the factory changed the common way of storing water in 601,604 thickener into the operation mode of 601 thickener and settling tower water storage, relieved the pressure of system overload caused by excessive amount of slime water, meanwhile To lower the 604-concentration pool into an accident pool, to solve the accident under the running water pollution of the environment. The technical transformation of the whole slime water treatment system to increase the buffer space of about 1,000 cubic meters, capacity increased nearly 10 times, which greatly improved the stability of slime water treatment system operating capacity, even in the rainy day can ensure the stable operation of the system , Which provided a powerful guarantee for continuous and efficient operation of heavy medium coal preparation plant.
