Description

Useless rock wool processing system

Technical Field

The utility model relates to the technical field of rock wool treatment devices, in particular to a waste rock wool treatment system.

Background

Rock wool containing more slag balls in the production of rock wool boards is rejected to become rock wool board waste, and meanwhile, the molten waste glass is also one of the wastes in the production process of rock wool. Rock wool waste is difficult to degrade and pollutes the environment, and is mostly treated in a landfill mode for a long time. However, the rock wool waste is produced in a small quantity of thousands of tons and more than ten thousand of tons every year, the dumping and burying modes not only waste manpower and transportation capacity, but also face great environmental protection pressure, and partial pollutants in the buried rock wool waste can permeate into soil to cause secondary pollution.

In order to solve the problem of secondary pollution of land, many enterprises adopt an incineration mode to treat rock wool waste, but smoke is generated in the process of incinerating the rock wool waste, and the smoke contains nitrogen oxide, dust, hydrogen sulfide and the like, so that the smoke is directly discharged into the atmosphere, and the problem of secondary pollution of tail gas exists.

Simultaneously, burn the solid waste heating back, the residue still is the solid cubic, and the decrement effect is not obvious, in order thoroughly to reduce the solid residue volume, and the packing of being convenient for is outward transported, designs one set of useless rock wool collecting system on original dust recovery system and gas processing system, makes whole process semi-automatization operation, and the dust that extrudees the residue process simultaneously is discharged after being purified by original dust recovery system.
