Sludge treatment equipment includes sludge dewatering equipment and drying equipment.

1. Usage of sludge treatment equipment:

Sludge treatment equipment Sludge dryer is a kind of drying equipment with low fuel consumption and high efficiency. The equipment adopts the downstream drying process, which is especially suitable for the rapid drying of high-humidity sludge that needs to be preserved. Main uses: The machine is compact in structure, easy to install and debug, and occupies a small area. Both the drum and the crushing device adopt stepless speed regulation, which can meet the drying requirements of different materials. This machine can be used with heat sources using different fuels (such as coal, heavy oil, natural gas, etc.). This machine is suitable for drying waste materials with high water content and high viscosity, such as beer waste grains, starch waste grains, rice bran waste grains, and various residue materials, such as bean dregs, sugar dregs, fruit dregs, sauce dregs, livestock manure, peat and other high-humidity materials.

II. Working principle of sludge treatment equipment:

High-humidity sludge is directly sent to the drum crushing dryer by the feed screw, and is repeatedly picked up and scattered by the beating board on the inner wall of the drum. After being scattered by the crushing device, the material fully contacts with the high-temperature medium with negative pressure, thus completing the heat and mass transfer process. Due to the inclination of the drum and the effect of induced draft, the material moves slowly from the feed end, and is discharged from the discharge screw after drying, and the tail gas is discharged into the atmosphere after dust removal by the dust collector.

The sludge treatment equipment adopts the downstream drying process, which is especially suitable for the rapid drying of high-humidity sludge that needs to preserve nutrition, such as treating fresh chicken manure, which can achieve the purposes of drying, sterilizing, deodorizing and preserving nutrition at one time. The drum of this machine is equipped with a high-speed rotating crushing device, which increases the contact area between sludge and drying medium. Some unique designs inside the equipment make it difficult for sludge to adhere to the operating plate and the cylinder wall, and the whole machine has good thermal insulation and sealing performance. The thermal efficiency is much higher than that of the ordinary drum dryer.

The sludge treatment equipment is compact in structure, easy to install and debug, and occupies a small area. Both the drum and the crushing device adopt stepless speed regulation, which can meet the drying requirements of different materials. The machine can be used with heat sources using different fuels (such as coal, heavy oil, natural gas, etc.).

III. Composition of sludge treatment equipment:

The complete sludge treatment equipment mainly consists of drum crushing dryer, combustion furnace, feed screw, discharge screw, conveying pipeline, dust collector, air shutoff device, induced draft fan, control cabinet, etc.

IV. Usage of sludge treatment equipment:

Sewage will produce a large amount of sludge after precipitation treatment, and even after concentration and digestion treatment, the water content is still as high as 96%.
