Application of sludge dewatering hydraulic filter in the treatment of vanadium pentoxide and other v

  With the application of sludge dewatering filter in the treatment of vanadium pentoxide and other vanadium products, the requirements of environmental protection are constantly strengthened
Wastewater treatment in iron and steel industry is no longer a simple process
The whole design process needs to be carried out in strict accordance with relevant specifications
The original sludge treatment is also strengthened locally, and the requirements are higher and higher
The sludge dewatering filter has become an important link in the wastewater treatment project of iron and steel industry
The moisture content of sludge in the sludge tank is high
In order to realize the solid-liquid separation, mechanical dewatering must be used to separate the water in the liquid sludge to a great extent and make the sludge plastic solid
At this time, the sludge is convenient for outward transportation and disposal, and the volume of dewatered sludge is greatly reduced, which not only reduces the secondary pollution to the environment, but also creates extremely favorable conditions for the comprehensive utilization of sludge resources
At present, the high-pressure sludge filter press has been increasingly used as the main machine for sludge dewatering in the iron and steel industry to prevent the use of belt filter press in radical processes, Various disadvantages of plate and frame filter press (if sludge dewatering is carried out in the open air, the on-site environment is poor, the amount of water and reagents is large, there are many vulnerable parts, the operation cost is large, the equipment volume is large, the capital construction cost is high, the automation level is low, the labor intensity is high, and it is not suitable for continuous operation)
The use of high sludge filter press for sludge dewatering can ensure that the waste gas does not overflow, the sewage does not flow out, the sludge does not fall to the ground and the sludge is automatic High degree, less vulnerable parts, low drug consumption, convenient continuous operation and low interest in operation http://www

html The particularity of vanadium pentoxide and other vanadium product sludge determines the requirements of sludge dewatering equipment
The special high-pressure sludge filter press for steel plant adopts high-pressure feeding and high-pressure filter press technology
Hydraulic plunger pump is used for feeding
The feed pressure is up to 2MPa
After feeding, the hydraulic cylinder directly presses the filter plate for pressing
The pressing pressure reaches 60-110kg / cm2, which is 6-10 times higher than that of ordinary diaphragm machine
Due to high pressure, water can be separated quickly, and the working cycle is 2-4 times shorter than that of ordinary filter press
In addition, the machine has a high level of automation
The electric control system adopts PLC programmable controller mode and touch screen operation panel, which can automatically feed, press, unload and clean the filter cloth
The cleaning of filter cloth depends on compressed air instead of water and is completed automatically according to the working sequence, which saves the sequence of manual unloading and manual cleaning of filter cloth when the ordinary filter press works, saving labor and labor
