On the premise of giving full consideration to the operating conditions of the equipment, on-site installation environment and deodorization environment, our company has provided assembling complete sets of treatment equipment for sludge concentration system, sludge modified conditioning system and sludge deep dehydration system.
Main process:
The sludge with moisture content of about 99.2% was transported by screw pump from the sludge tank to the multi plate screw thickener. The sludge moisture content reached 90%~93%. It was then modified by polymer dosing, and the treated sludge was compressed and dehydrated to less than 60% by our super high pressure filter press.
Sludge thickening system
Working principle
Multi plate screw thickening system includes sludge pump, multi plate screw thickener, full automatic PAM preparation device, PAM polymer dosing pump, and so on.
Its core equipment is multi plate screw thickener. It integrates automatic controlling cabinet, flocculation conditioning tank, sludge thickening body and filtrate collection tank. Sludge concentration can be completed efficiently and continuously under the condition of full automatic operation. The collected filtrate will eventually be flowed back or discharged.
Filtration body
It is composed of fixed rings, moving rings, screw shaft, gasket and connecting plates. Fixed rings are connected by a number of screws. The gasket and moving rings are installed between the fixed rings. The fixed rings and moving rings are made of wear-resistant materials, which makes the life of the whole machine extended. The screw shaft is inserted between the fixed rings and moving rings, and the moving rings are hollow on the screw shaft.
Sludge conditioning system
Working principle
Sludge conditioning system is a general term for sludge polymer dosing conditioning equipment. It includes PAM preparation device, PAM dosing pump, FeCl3 solution storage tank and solution pump, curing agent bin and preparation (storage) of three agents for feeding screw and dosing equipment. By adding agents to the original sludge, the physical properties of the sludge can be changed, and the efficiency of sludge dewatering can be effectively improved.
Mixer
The mixer is installed on the polymer dosing device. It has unique structure and appropriate speed. Thus the solution can be homogenized without destroying the polymer chain.
Sludge pressing system
Working principle
The sludge is transported to the super high pressure filter press by the feeding pump of the press machine after dosing and adjustment. With the increase of the feeding capacity, pressure is gradually formed in the chamber of the press, and the sludge is squeezed at the first time. After a certain period of time, the entire press is filled with sludge. At this point, we should close the feeding inlet, and the press starts pressing. Super high pressure filter press can directly act on the filter frame by oil pressure and squeeze to reduce the volume of the filter chamber to conduct the deep dewatering of sludge.
Electronic control system
The electronic control system meets the requirements of equipment operation. Its operation modes are divided into two modes. The one is local operation, and the other is remote operation. The control box is responsible for the on-site start, stop and control and overload protection of the equipment.
