Treatment process and energy saving measures for stainless steel sludge dewatering equipment

- Jun 12, 2019-

Stainless steel sludge dewatering equipment uses a variety of treatments, such as sludge digestion, which is the process of using microorganisms to convert substances in sludge into more stable substances under oxygen or anaerobic conditions; aerobic digestion The sludge is aerated for a long period of time, part of which is degraded and stabilized by aerobic microorganisms; and there is anaerobic elimination. Under anaerobic conditions, the sludge is degraded and stabilized by anaerobic microorganisms. the process of.

 

In addition, medium temperature digestion, high temperature digestion, sludge concentration, sludge washing and so on are all processes of stainless steel sludge dewatering equipment. A sludge pretreatment method for sludge dewatering performance. The sludge is washed with clean water or waste water to reduce the alkalinity of the digested sludge, save the sludge treatment dosage, and improve the sludge filtration dewatering efficiency.

 

In order to achieve the purpose of energy saving of the stainless steel sludge dewatering equipment, the bottom of the cone portion of the equipment drum is uniformly opened with a slag discharge port in the circumferential direction, and the slag discharge port is processed into a plane in parallel in the tangential direction, thereby avoiding the solid phase material before leaving the drum Collision with the slag discharge, wear, during the slagging process, the solid phase material can leave the rotating drum earlier, saving.

 

At the same time, the large port of the stainless steel sludge dewatering equipment has an overflow port, and the overflow port is provided with an overflow plate which can adjust the liquid pool, and the liquid material directly leaves the rotating drum of high speed to reduce the acceleration of the liquid material by the rotating drum. , saving, applied to clarify Chen He, the effect is more obvious. In addition, a dual-motor variable-frequency feedback drive system is adopted, which consists of a main inverter and a secondary inverter. Under the action of the differential speed, when the auxiliary motor is in the power generation state, the DC common bus is fed back to the main motor to save.
