SLUDGE DEWATERING PLANT - 2

Sludge dewatering plant is designed for dewatering of oily slime water which is appeared in the result of urban runoff settling. The equipment is delivered in block-boxes and don't need permanent construction. The plant has all needed technological and auxiliary equipment for automatic mode of operation. The equipment is housed in blocks with dimensions 6х2,4х2,9m (each). Block-boxes are made on base of standard twenty-foot and forty-foot containers with fire resistant covering. Complex is equipped by heating system, ventilation system, air condition system, light system, air pollution...

3. THE CONFIGURATION OF THE SLUDGE DEWATERING PLANT THE CONTAINER FOR DECANTER CENTRIFUGES The container for decanter centrifuges is made on base of standard twenty-foot container. All the equipment is made in explosion-proof version. There is the double-leaf gate (open for 180°) on one of the side face and single-leaf door with dimensions 850 x 2000 mm on the other side on container. The roof is equipped by the access door for the repair works and scheduled maintenance. The container has two aluminum windows with dimensions 1000 x 1200 mm. So the container is equipped by explosion doors....

4. TECHNICAL DESCRIPTION OF THE PLANT SOLID BOWL CENTRIFUGES (DECANTER) Feed inlet Lliquid discharge by gravity Solids discharge Separation of the solids is going to the cylindrical bowl, where the solids are collected on the walls by centrifugal force. The decanter's drum is driven by the electric motor with vee belt drive. Starting and working speed are regulated by variable frequency driver. Inner scroll conveys the separated solids toward the conical end of the bowl. At the end of the bowl dewatered solids are discharged through the output access. The feeder is driven by through the...

STEAM-WATER HEAT EXCHANGER Plate steam-water heat exchanger is used for the heating of the product. This measurings were done on the following parameters: pressure steam-water heat exchanger can heat 20 m³/hour of the sludge from 5 °C to 80°C. The temperature is regulated by means of control valve and temperature detector. Steam is gone on the pressure 1,5 bar. On this Product preparation system with steam water heat exchanger Description
