Cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement production line. The advantages of disposal of sewage sludge by cement kiln than by professional incinerator

High treatment temperature

Temperature in cement kiln can reach 1800 ℃,the burn rate of harmful ingredient in the mainly organic matter can up to 99.999%, even the stable organic matter can also be completely decomposed

Burning atmosphere stable

Cement kiln is a large rotary cylinder, not only can handle large amounts of waste, and can maintain a homogeneous, stable burning atmosphere.

Long Incineration

Sludge stay a long time at the high temperature furnace, burning fully

Large-scale treatment

New cement kiln treatment sludge accounted for about 2% of kiln production.

CHAENG cement kiln

Alkaline cement kiln atmosphere

Avoid "secondary pollution" resulting by burning exhaust gas of common incinerator

Cement kilns burning hazardous waste

Allows solidification of potential presence metal elements in hazardous waste, plays a dual role of exhaust gas purification and heavy metals high temperature curing in mineral admixture.

Cement kiln system is operated in Negative pressure

Smoke and dust will not spill out, to prevent the re-contamination radically in the process.

Cement kiln treatment sludge

Because of the sulfur absorption effect of theburning process, integrated emissions of pollutants was improved and reduced.

Tefractory bricks in Cement kiln

Firebrick, raw materials, kiln coating and clinker are alkaline, can absorb SO2, thereby suppressing their emissions.
