Integrated Sludge Handling

The heat transfer area within each effective volume is very large. The temperature of heat medium which can be which can be water vapor or liquid type such as hot water, thermal oil and so on is ranged from 0 ℃ to 320 ℃. With the heating method of indirect conduction, there is no heat loss taken away by air, so all the heat is used to heat materials.

The dryer consists of a transparent thermo shell in which the HUBER Sludge Turner SOLSTICE® distributes the sludge all over the area. In addition heat (for example at 50° C) can be added via floor heating. Heat input via heating coils is also possible (usually with temperatures above 70° C). External heating can be operated with exhaust heat from a block heat and power plant or by means of a heat pump which uses the heat contained within wastewater . The special wedged stirring and heat transfer blade in the equipment has high heat transfer efficiency and self-cleaning function of heat transfer surface. The hollow shaft is lined with wedged hollow blades, and the thermal medium flows into the hollow blades through hollow shaft.

These products are available as OEM and ODM orders along with customized packaging options. You can select from a wide variety of vacuum sludge drying machine at depending on colors, sizes, designs and utilities. These vacuum sludge drying machine are equipped with distinct inlet air temperature and outlet air temperature with centrifugal atomization drying methods for enhanced performance.

The lining should have a minimum 1.5% slope to a center drainage area that is not paved. A minimum 100-mm (4-in.)-diameter perforated pipe would convey the drainage away. The main advantages of paved drying beds are that front-end loaders can be used for easy removal of sludge cake, augur mixing vehicles can speed up drying, and bed maintenance is reduced. However, for a given amount of sludge, paved drying beds require more area than do conventional sand drying beds.

During the operation of the equipment, the inner cavity of the rotary table is filled with heat medium. The heat medium can use medium and low pressure steam , heat conducting oil or high pressure hot water, and transfer the heat required by the drying product to the drying object through the outer surface of the rotary table. Kenki is a sludge dryer based on the unique design of self-cleaning double screw conveyors that guarantees the effective process of moving the feedstock.

Our engineer is available to service machine overseas and train your workers how to use the machine and provide the installation and commissioning service at your site. The stator is equipped with steam doom,which is used to containing waste steam. The rotary drier is mainly composed of stator, rotor and driving device. Some of these can also be used for mud dewatering, mine tailings, pond clean-up and dredging. AS-H Belt Thickeners with integrated polymer mixing for small to medium capacity. • When the cake cracks and the vacuum is lost, the vacuum pump is shut off.

The dewatered sludge at the dewatering stage needs to reach a minimum d.s. of 25% and is discharged into the thermal stage as a fine-grained spray. The CENTRIDRY® system will process municipal and industrial sludges with an incoming d.s. of 2% – 7% and produce, within seconds, fine grained sludge granulate with 60% – 90% d.s.

There are two parallel rotary shaft inlaid with interlaced paddles in the jacket shell. Each shaft is inlaid with hollow fan-shaped paddles staggered at a certain interval, and the shaft rotates at a low speed. The heat medium enters the hollow rotary shaft and paddle through the rotary joint installed at the end of the rotary shaft.

Therefore, proper measures should be carried out in painting industry. Water pollutants produced in automobile industry such as resin, active agent, phosphate and etc. which will cause serious environmental pollution. Painting sewage in automobile industry holds complex ingredients without regular emission rules. The drying temperature can be easily controlled by PLC +Touch Screen control system.

The entire process including the material feed, the mixing, drying and subsequent pelletization is monitored by a Siemens S SPC control unit. All sensor data, temperatures, flow rate volumes, pressures, speeds, run times, etc. are continually recorded. An active support unit scans the data and if deviations to the target value tolerance are noticed, then the intended requirements are carried out. The entire process is visualized by a touchscreen panel on the HMI. Important functions, like the opening and closing of the chamber valves and the filter cleaning, require compressed air.

Such programs can help to minimize nutrient pollution effects as well as reduce financial burdens on societies for costly treatment plant upgrades. Simpler operation.It takes only 180 kWh electricity to remove 1 ton of water from wet sludge. 1 kWh electricity alone is capable to remove as much as 4.2 kg of water from wet sludge, comparing to normal 1-2.5 kg water per kWh. Save energy bill and reduce carbon footprint.Reduce wet sludge volume by 67% and weight by 80%. The mechanism is simple, and there are few parts to be tested, which is convenient for maintenance. The operator uses the touch operation panel for production operations.
