"The centralized sludge treatment project is a new highlight of our work, which is of great significance to the harmless, reductive and resource-based treatment and disposal of municipal sludge." In the past, the treatment of sludge was sent to landfill for sanitary landfill, although it is also in line with relevant standards and requirements, but it is not as environmentally friendly as now.
Sludge added straw and culture bacteria, mixed, fermented into organic fertilizer, in addition to more environmental protection, sludge centralized treatment has an important role, that is to let the once "useless" sludge transformed into organic fertilizer. The sludge treatment equipment designed and produced by Shandong Tianyuan Machinery Manufacturing Co., Ltd. is a kind of drying equipment with low fuel consumption and high efficiency. The equipment adopts the downflow drying process, which is especially suitable for the fast drying of high wet sludge which needs to preserve nutrients. This machine is compact in structure, easy to install and debug, and occupies a small area. The roller and crushing device adopt stepless speed regulation, which can adapt to the drying requirements of different materials. The machine can be used with different fuels (such as coal, heavy oil, natural gas, etc.). The equipment is suitable for dry and sticky bad materials with high water content, such as beer grains, starch grains, rice bran grains, all kinds of slag materials, such as soybean residue, sugar residue, fruit residue, sauce residue, livestock and poultry manure, mud and grass carbon and other high humidity materials.
The high humidity sludge is directly fed into the drum crushing and drying machine by the feed screw, and is repeatedly picked up and scattered by the sheet on the inner wall of the drum. After being dispersed by the crushing device, the material is fully in contact with the high temperature medium with negative pressure, and the heat and mass transfer process is completed. Due to the dip Angle of the drum and the effect of diverting the wind, the material moves slowly from the feed end, and is discharged by the discharge spiral after drying. The tail gas is discharged into the atmosphere after being dusting by the dust collector.
It is understood that the current sludge centralized treatment center can handle 150 tons of sludge with water content below 80% per day, which is popular with buyers after turning waste into treasure and organic fertilizer.
