Description
Technical field
The utility model relates to a kind of desalinization Treatment of Sludge filter press, specifically a kind of desalinization Treatment of Sludge program controlled automatic diaphragm filter press.
Background technology
Desalinization also claims " seawater desalination ", namely removes salinity in seawater to obtain the technical process of fresh water.Desalinization is the increment technique of increasing income that realizes the water resource utilization, can increase the fresh water total amount, and is not subjected to space-time and climatic effect.A large-scale desalinization project very complicated system engineering often.With regard to main processes, comprise sea water preprocessing, desalinization Treatment of Sludge, desalination, desalination water post processing etc.In desalting process, produce a large amount of mud.According to " GB18918-2002 urban wastewater treatment firm pollutant emission standard ", require: mud should carry out stabilization processes, after stabilization processes, should reach moisture content (%)<65.So Treatment of Sludge is the important component part of desalination treatment system, must fully be paid attention to.The purpose of Treatment of Sludge is to make mud decrement, stable, innoxious and comprehensive utilization.Normally used cell process process has: concentrated, stable, sludge conditioning, mechanical sludge dewatering.
Mechanical sludge dewatering is to using the pressure differential on filter medium two sides as motive force, makes sludge water content be forced through filter medium, forms filtrate; And solid particle is trapped within on medium, forms filter cake, thereby reaches the purpose of dehydration.Dewatering has vacuum suction filter method, filter press technique and centrifugal process etc.Vacuum filtering and dewatering application at present is less, and the machinery of use is called vacuum filter, can be used for the dehydration of primary deposition mud after pretreatment, chemical sludge and digested sludge etc.The characteristics of vacuum filter dehydration are to produce continuously, and stable, operation is more complicated, and operating cost is higher; The motive force of dewatering in centrifugal dehydration is centrifugal force, promotion to as if solid phase, the size of centrifugal force can be controlled, even several ten thousand times of the large hundred times of force of gravity, therefore the effect of dehydration is also than concentrated good.But the centrifuge continued operation, the workplace sanitary condition is good, and floor space is little.But power consumption is large, and noise is large; Filter-press dehydration adopts plate and frame filter press, is widely used in the industry of the various Separation of Solid and Liquid such as chemical industry, pharmacy, dyestuff, metallurgy, coal separation and sewage disposal.Its simple structure, filtered driving force is large, is applicable to various mud, can meet " GB18918-2002 urban wastewater treatment firm pollutant emission standard " requirement, is the capital equipment in Separation of Solid and Liquid.But conventional plate and frame filter press can't meet the particular surroundings of Seawater, for the filter press of desalinization, need to meet himself special requirement.In order to overcome the deficiencies in the prior art, be necessary to develop the filter press that meets the desalinization specific (special) requirements.
Summary of the invention
In order to fill up the blank of existing filter press technology, the utility model provides a kind of desalinization Treatment of Sludge program controlled automatic diaphragm filter press, and this filter press meets in " GB18918-2002 urban wastewater treatment firm pollutant emission standard " mud and carries out moisture content (%)<65 requirement after stabilization processes; Solved the endurance issues of equipment and material in the corrosive environment of sea water; Solved the corrosion-resistant and cleaning problems of corrosive environment of sea water lower pulling plate cart slideway; Solved filter cloth seawater corrosion resistance problem; Solved filter cloth automatic washing problem; While having solved the filter cake discharging, be difficult to the problem of coming off; When having solved Filter Press or having cleaned filter cloth, filter leakage or the filter cloth cleaning fluid problem of trickling everywhere.
The technical scheme that its technical problem that solves the utility model adopts is: for achieving the above object, a kind of desalinization Treatment of Sludge that the utility model provides with the program controlled automatic diaphragm filter press by rack section, automatic pulling plate part, membrane filtration part, Hydraulic Station part, electric control box part, turnover panel part, filter cloth high-pressure wash part with bend a part and form.Because filter press is inner, outside all is in the corrosive properly media environment, body and internal material are had to corrosivity.For improving the filter press durability, with the contacted metalwork of seawater or employing 316L stainless steel material, or adopt the outer solidifying anti-corrosion material of cyanogen that is coated with to do preservative treatment.Nonmetallic materials adopt the material of the seawater corrosion resistances such as polypropylene, FRP fiberglass reinforced plastics, second the third copolymerization engineering plastics, UPVC and EPDM rubber.
