Some Points Comparison between decanter centrifuge and belt filter press

1. Decanter centrifuge is suitable for all kinds of sludge; belt machine is also suitable for all kinds of sludge, but for oily, viscous, remaining activated sludge, it needs a large amount of medicine and dehydration is difficult.

2. The problem of feed control

The D ecanter centrifuge can automatically adjust the slip and torque according to the change of the feed concentration, and the belt machine must be manually adjusted.

3. Problems of solid recovery rate and dosage

The solid recovery rate of the D ecanter centrifuge is indeed higher than that of the belt machine, but this does not mean that the solid recovery rate of the belt machine cannot be used if it is low. In fact, the belt filter must be returned to the front and reprocessed.

The dosage of medicament is added. A 15 × 104t / d urban sewage treatment plant designed by the author adopts a decanter centrifuge for dehydration. The measured consumption of PAM per ton of dry sludge after production is 1.7-2.0kg. The lower the consumption of medicine with machine (PAM) is generally 4kg / (t [dry mud]).

4. Power consumption problem

The difference in power consumption is not as claimed by the manufacturer of the machine. It is actually controversial. The centrifuge manufacturers will also say that their centrifuges use less electricity. The author speaks a jargon here: power consumption differs mainly depending on the model and the amount of processing capacity.

The noise of the centrifuge is large, but the noise with the machine is not the machine itself, mainly the sound of washing water, the sound feels better than the centrifuge;

5. The life of the machine

The bearing life of a good-quality belt machine is theoretically 20a, which is similar to the life of the host machine. The filter belt needs to be replaced frequently. The filter belt is generally replaced continuously for 2000h operation. If it is intermittently operated and maintained well, then it depends on the length of use and shutdown In contrast, regardless of whether it is a domestic or imported belt machine, the filter belt can generally be replaced with a domestic filter belt, so the cost of replacing the filter belt is not high, and the current domestic equipment of the decanter centrifuge is reliable, stable, and easy to maintain and maintain.

In theory, the running time of the belt machine can also run for 24 hours. Of course, the continuous operation of the belt machine is not as reliable as the centrifuge.

6. Calculation of operating expenses

When the belt filter press dehydration machine manufacturer calculates the dehydration and centrifuge core operating costs, there are many problems in the calculation method used. The operating costs mainly include: pharmaceutical fees, electricity costs and water costs. In addition to the belt machine, there are downtime costs and flushing costs. The author took an 8 × 104t / d sewage treatment plant as an example to calculate the actual operating cost of sludge treatment. Therefore, from the perspective of operating costs, the use of centrifuges and Not higher than with the machine.

Methods for reducing the noise and vibration of decanter centrifuge

The principle of the decanter centrifuge is to use the centrifugal force brought by the high-speed mechanical rotation to achieve the purpose of solid-liquid separation, and some noise and vibration will be generated during the operation of the equipment. It will affect the surrounding environment of the device, so when using the device, some techniques can reduce noise and vibration. The following are some common technical solutions:

When the whole set of equipment runs empty and the inlet and outlet are closed, the average noise at 1 meter around the equipment will not exceed 85dB when tested in the manufacturing plant.

When the decanter centrifuge is idling, without water, and tested in the manufacturer, the vibration is not higher than 5mm / S. If the vibration is too large during the operation of the machine, in order to ensure safety, it can be stopped by the vibration switch.

1. There is no need to disassemble the machine when there is a material blocking failure, only need to start the automatic slag discharge of the screw pusher to clear the accumulated material.

2. After the decanter centrifuge is shut down, backwash must be performed. Backwash only needs to open the flushing water valve and flushing water pump to complete.

3. The centrifuge is equipped with emergency shutdown, motor overheating / overload, screw feeder overload, bearing temperature, vibration and other protection functions.

GN can not only provide users with Dewatering Decanter Centrifuges, rely on GN rich production line of separation and conveying equipment. GN can also provide users with turnkey solutions for the material dewatering process, including solutions for material transportation, classification and dewatering.

With complete machine monitoring and alarm system. When overload, short circuit and lack of phase occur in the course of operation, the centrifuge will be automatically protected; the speed of centrifuge, bearing temperature, vibration of the whole machine, lubrication system oil pressure, main and back motors’ current, push torque and other operating parameters are monitored in real time, and alarm is started when the parameters are abnormal. In case of blocking materials, the device will automatically switch to the plugging procedures; if plugging procedures cannot be dredged, it will then automatically switch to the shutdown procedures to ensure the safety of personnel and equipment.
