SLUDGE DEWATERING PLANT

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 6x2,4x2,9m (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...

2. TECHNICAL CHARACTERISTICS Description Capacity by injected product, m³/hour Cake moisture after dewatering, not more than % The input electric power, not more than kW Service water, not more than m³/hour Water consumption for technological flushing, not more than m³/hour (from time to time) * The plant can be made with the capacity from 5 to 80 m³/hour.

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...

PRODUCT PREPARATION SYSTEM Application: - Heating of the product to the need temperature - Sludge filtering (from the big solids up to 8 mm) - Costing of input sludge - Reversing of sludge input in case of the insufficient heating of the sludge - Flushing of the technological equipment All the equipment is mounted on the separate frame with dimension 1540 x 5000 mm. The system is fixed on the monolithic foundation near the container with decanter. There are following accesses on the product preparation system: - Dn 80 - sludge input from the pumping system - Dn 65 - sludge input to...

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...

There are two eccentric pumps, one is for the reserve. Clutch with NTC temperature detector and junction block IP55 is integrated to the pump stator and protects the pump from dry running. Pressure relay sensors with the settable trip limit protect from gage pressure. Pumped medium Sludge Gage pressure Rotor rated revolutions, r/min Drive...

SCREW FEEDER •Screw feeder is made for the transfer of solids from the decanter to the outer tank. Loading hopper of the feeder is located under the decanter. The transporting direction of the feeder changes it the time of decanter stopping. Liquids discharging during these stop by drain line.

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
