Sludge Filter Press
Sludge Filter PressThis belt filter press is suitable for urban wastewater treatment plants, sudo sludgefilter pressIn manufacturing, electroplating, papermaking, leather, printing and dyeing, metallurgy, work, food, brewing and environmental protection projects in the wastewater treatment process of sludge dewatering, in the work of production can also be used for solid-liquid separation of occasions, it is the ideal equipment for environmental management and resource recovery. It can also be used in the solid-liquid separation or liquid leaching process in the work production. It is widely used in domestic environmental protection projects.
Sludge filter press working principle
The working principle of the sludge filter press is that the material to be filtered is fed from the feed holes of the thrust plate into the filter chambers through the feed pump under a certain pressure, through theFilter Press Cloth, the solids are retained in the filter chamber and gradually form a cake; the liquid is discharged out of the machine through the outlet hole. As the filtration process proceeds, the cake filtration begins, the thickness of the cake gradually increases, and the filtration resistance increases. When the filter cake reaches a certain thickness or fills the whole frame, the filtration is stopped. Open the plate and frame, unload the cake, clean the filter cloth, reload and close for the next cycle. Sludge filter press is mainly used to remove the suspended matters such as sediment, corrosion inhibitor, impurities, sulphur ether and so on contained in the sludge by means of sludge filter press to remove the impurity particles in the sewage and avoid the accumulation of sludge in the whole system, which will affect the water quality of the treated sludge. The structure of sludge filter press is mainly composed of five main parts: frame, automatic pulling plate, filtration, hydraulics and electrical control. According to different needs, it may also increase the receiving plate, flap, mud storage hopper, water washing system, filter cloth zigzag frame and so on.
Sludge filter press operating procedures
1、Pressing: Organise the filter cloth, require the filter cloth to be flat and without folding. Then insert the weighted rod into the jack of the screw jack, adjust the direction valve, and rotate the jack in clockwise direction until it can not be pressed by one person's strength.
2, Back: Insert the weighted rod into the jack of the screw jack, adjust the directional valve and rotate the jack in the counterclockwise direction.
3, if in the pressure or backward process, there is a slippery phenomenon, indicating that the direction of the direction of the valve is adjusted wrong, change a direction of operation can be.
4, the size of the compression force is generally a person's strength can be, if there is a leak in the filtration process, you can increase the compression force appropriately.
5, the end of filtration, return to the pressure plate, pull open the filter plate one by one to unload the cake, after unloading the cake to sort out the filter plate, filter cloth, such as found that the filter cloth is broken in time to repair or replace.
Sludge filter press filtration
When filtering different materials and the same material due to different water content and even temperature, the effect of filtration (speed, water content) may be different, and some materials even need to add filter aids such as Cao, flocculant, calcium carbide slag, etc. before filtration in order to adjust the filtration characteristics of the material. So its filter cake will not necessarily be exactly the same.
1. The filter cloth and filter plate should be checked before filtration, and if washing or blowing is required, the washing plate, non-washing plate and the washing hole and blowing hole should be checked to see if they are smooth.
2. Whether the compression force is sufficient.
3, open the filtrate outlet valve, start the feed pump, and gradually increase the feed valve depending on the filtration speed and filtration time, the filtration pressure can be gradually increased, generally not more than 0.6Mpa (plate and frame type is not more than 0.4MPa) at the beginning of filtration filtrate may be turbid, it is due to the material does not form a pre-coating caused by the filter cloth, you can continue to use it, and later will naturally turn clear. If there is a big leakage between the filter plates, you can increase the compression force appropriately. As the filter cloth has capillary phenomenon, there will be a small amount of filtrate seepage is normal.
4, monitor the filtrate, such as found out of muddy liquid open flow type that is closed the turbid water nozzle, dark flow type can stop filtering, check the filter cloth and sewing or replacement.
5, if the pneumatic diaphragm pump can adjust the pressure reducing valve, a one-time adjustment of the filtration pressure, in the filtration process without human operation. If the screw pump and other feed pumps are used, not only the reflux system should be installed, but also the size of the reflux valve should be adjusted at any time according to the change of filtration pressure in order to control the filtration pressure, which needs to be operated by a person, or else the equipment will be damaged.
6, when the filtration pressure is large, the water is small, can be regarded as the end of filtration, return the pressure plate, such as found that the water content of the cake is large, can close the pressure plate to continue filtration.
7If the filtration time is too long or the filter cake can not be shaped, you should consider reducing the water content of the material, such as increasing the settling time, adding a concentrated sedimentation tank or adding flocculants and filter aids (quicklime, diatomaceous earth, perlite) to replace the filtration media and other methods to solve the problem.
8、If the filter cake needs to be rinsed, the open-flow type closes the outlet on the washing plate, closes the feed valve, opens the washing water valve, and releases the water for rinsing, the pressure of the rinsing water is generally not greater than the rated filtration pressure of the equipment, and the rinsing time should be determined according to the effect of rinsing, such as the effect of one rinsing is not desirable, it can be rinsed several times during the filtration process.
9. In order to reduce the water content of the filter cake, compressed air blow-drying method can be used, which is the same as the flushing method, and the method of feeding air into the feed hole or the use of diaphragm press type filter press can also be used.
Advantages of sludge filter press
Sludge dewatering is a crucial part of sludge treatment. If the sludge dewatering effect is good, the sludge cake with low water content, not only the volume is greatly reduced to achieve a very good reduction, but also can be directly on the sludge for further disposal, eliminating the cost and time of drying, secondary dewatering of sludge, and saving the number of times and costs of transporting sludge cake. Sludge filter press is the mainstream sludge treatment equipment in China's sludge treatment market, at present, most of the sludge treatment and disposal projects use sludge filter press for dewatering. So the choice of sludge filter press largely determines the final result of sludge treatment. The next step is to introduce to you what are the advantages about sludge filter press:
1、High sludge pressing force. In the past, filter press sludge dewatering sludge water content is lower to reach 50%, mostly between 60%-80%, while today many sludge filter presses are more final sludge water content between 15%-45%, so that the sludge is processed in a smaller volume, more filtrate, and get more resources.
2. High dewatering efficiency. The sludge treatment cycle is less than 40 minutes, thus the whole dewatering efficiency is 30% higher than that of ordinary filter press.
3. High degree of automation. Full-automatic series of sludge filter press can realise one-key control, for large sludge treatment project, it can adopt multi-machine network to realise remote control, and several sludge filter presses are managed by only one staff.
4. Low energy consumption. Due to the improvement of the efficiency of the sludge filter press, automation makes the ineffective operation of the sludge filter press reduce, thus realising low energy consumption operation. Processing the same sludge, the energy consumption of sludge filter press is 1/3 lower than that of ordinary filter press, which reduces the sludge disposal cost for sludge treatment enterprises.
5, Comprehensive and reliable performance. In the production design of sludge filter press, many filter press manufacturers have very rich experience, so as to control the better structural design, so that the performance of the whole machine to operate reliably, to achieve ultra-low failure rate.
