Sludge Dewatering Equipment System for Desulfurization Wastewater

Product Specification

Apoaqua's sludge dewatering machine can be used for sludge treatment in power plants. A large amount of sludge will be produced during raw water pretreatment and desulfurization wastewater treatment.

Compared with other dewatering equipment, the sludge dewatering machine runs smoothly and quietly, with less noise and reduced wear between parts. It can run continuously and automatically, which can greatly reduce the cost of use.

Power Plant Sludge Dewatering Machine Structure

It mainly includes: variable frequency mud pump, flocculation mixing tank, fixed ring and moving ring, automatic dosing system for coagulant aid, and spray water system.

The sludge discharged from the raw water pretreatment system enters the flocculation mixing tank. After mixing with the coagulant aid, stir evenly, and after agglomerating into larger slag blocks, enter the dehydration component to complete dehydration. The system includes a flushing and watering system to intermittently rinse a small amount of mud residue in the gaps of the dehydration components to keep the equipment clean.

Sludge dewatering equipment PAM automatic dosing device. If customers need, we can provide it for them. Its presence can greatly reduce the cost of chemical agents. The equipment includes: a dry powder hopper, a preparation tank, a maturation tank and a storage tank. The polyacrylamide dry powder is accurately and evenly fed into the water distributor by a feeding screw driven by a variable frequency motor. After continuous and uniform mixing with water, it falls into the preparation tank.
Dissolve and mix evenly with a stirrer. The mixed liquid flows into the maturation tank by gravity, and is further stirred and matured. Finally, it flows into the storage tank for standby use.
The automatic operation of the automatic dispensing device can be realized by controlling the liquid level switch of the storage tank. During operation, the preparation of the liquid is automatically started according to the liquid level in the storage tank. The prepared coagulant liquid can be controlled by the electric valve for feeding the coagulant metering box. Automatically add coagulant aid to the metering tank.

Advantage

Dewatering screw press can achieve continuous and stable operation. During operation, the screw speed is low, the noise is low, the equipment wear is small, and the maintenance workload is small. Combined with PAM automatic dosing device, DCS program control system is introduced to meet the requirements of remote operation and automatic control.

The bacteria and organic matter in the reclaimed water increase significantly, resulting in high sludge viscosity. When using a plate and frame dehydrator, mud blocks tend to stick to the filter cloth. At the same time, the specific gravity of biological sludge is relatively small, and the dehydration process of the centrifugal dehydrator is more difficult. The dewatering screw press can control the moisture content of the sludge and adapt to the dewatering of different types of sludge.

Application in desulfurization wastewater treatment in power plants. Choose a sludge dewatering machine that is suitable for the high sulfate and high chloride ion materials in the desulfurization system. Desulfurization waste cement slag also has a relatively high viscosity. Adhesion problems often occur during the operation of plate and frame dehydrators. The sludge dewatering machine can perfectly solve this problem.
