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.

Analysis of the use effect of Decanter centrifuge:

1) In the past, the volume of the biogas tank built by the farmer was too small, and the drainage time after the sewage entered the tank was too short, resulting in excessive discharge of sewage concentration. Use the decanter centrifuge to process the sewage before it sinks into the pool, which can effectively reduce the COD and BOD content of the sewage, reduce the operating load of the biogas digester, and thus achieve the reduction of sewage discharge;

2) The use of decanter centrifuge in advance can transform the feces in the fresh sewage into valuable fish feed or organic fertilizer. The separated sewage intermittently enters the biogas digester, so that the anaerobic digester can have a full digestion time, so that the active bacteria in the digester can reproduce more vigorously, the gas production is higher, and the content of gas methane is naturally higher High purity will be overcome naturally to solve the problem of abnormal operation of biogas generators;

3) The sewage treated by the decanter centrifuge enters the biogas digester, which can effectively solve the crust phenomenon of the biogas digester and eliminate the work of cleaning the biogas residue;

4) The use of decanter centrifuge can reduce the investment in the construction of biogas digesters, for example: a breeding or slaughterhouse that discharges 100 tons of sewage per day. If a matching decanter centrifuge is used for pre-treatment, it can reduce the 300 cubic anaerobic tank Construction investment, because the concentration of manure and sewage mixed into the pond is too high, the anaerobic time will need to be extended accordingly, so if a farm that discharges 100 tons of sewage per day, without decanter centrifuge treatment, then an anaerobic pond 1000 is needed -1200 cubic meters, if using decanter centrifuge can reduce the construction of 300-400 cubic meters.

 If the materials processed by the Decanter centrifuge contain flammable and explosive substances such as organic solvents, the centrifuge should have explosion-proof performance. The explosion-proof performance is determined according to the explosion-proof requirements of the process. The explosion-proof occasions involved in the past have only been proposed to be equipped with explosion-proof motors. In the past two years, most of the occasions where the processed materials contain organic solvents such as solvents have been required by nitrogen protection. In fact, to realize the explosion-proof in the true sense, centrifuges must take various measures in mechanical, electrical control, accessory configuration and other aspects.

For instance: electric control system: explosion-proof isolation barrier, non-contact energy consumption braking system, electrostatic grounding, automatic control of explosion-proof.

Mechanical system: explosion-proof motor, explosion-proof lighting, anti-collision measures, anti-static transmission belt.

Explosion-proof accessories: nitrogen protection device, nitrogen online detection, on-site explosion-proof control button.

GN Explosion proof electrical control panels or electrical control stations are used in hazardous Location. The Ex control panel is designed and built to operate in environments where concentrations of flammable gases, vapors, liquids or combustible particles pose risks of ignition and explosion. GN Solids Control provide explosion proof control panel with ATEX approval, IECEX Approval, China National explosion proof approval. The protection degree is up to IP65 for weather and dust proof.

GN explosion proof control panel enclosures are cast from heavy duty aluminum so that they cannot create a spark that could possibly ignite the vapors in a hazardous location. These heavy duty panels come with seals keep explosive fumes from entering the control panel. Moreover the GN explosion proof control panels are designed to contain an internal explosion without igniting the explosive vapors present in the hazardous area to make sure it is safe for the hazardous Zone 1 or Zone 2 areas.

GN Explosion Proof Pressurized Control Panel is popular used for VFD controland soft starter of motor, especially in high temperature ambient. The explosion proof pressurized control panel consists of main cavity and auxiliary cavity. The main cavity is pressurized cavity which includes electrical components, pressure check sensor system, ventilation air distribution system, and air conditioning system. The purging system works automatically to maintain a certain positive pressure inside the main cavity.

GN Solids Control is capable to provide you with IEC Ex, ATEX or CNEx Standard Positive Pressurized Control Panel control panels with Zone 1 or Zone 2 for hazardous locations. This will also suit the North America Class I Division 1 or Division 2 hazardous locations application.
