After adopting the structure, not only can the content of inorganic salt of a finished product be lowered to below 5ppm, but also water-washing times in a production process can be reduced, and therefore, the filter-pressing desalting device group has characteristics of being high in desalting velocity, low in salt residual amount, and simple and practical to operate, so that product quality is improved, desalting water consumption is lowered, sewage discharge amount is lowered, and cost is lowered.
Description
Technical field
The utility model relates to press filtration demineralizer group in a kind of industrial production, is the filter-pressing device group that a kind of industrial processes remove by filter solid salt in organic phase specifically.
Background technology
In some industrial production, can produce the inorganic salts such as a large amount of sodium chloride, for reducing the content of finished product inorganic salts, need repeatedly clean with large water gaging.The method inorganic salt content is high, quantity of wastewater effluent is large, production cost is high, complex operation, therefore needs a kind of new technical scheme to address the above problem.
Summary of the invention
The purpose of this utility model be to provide a kind of can be easy and simple to handle, cost-saving and can improve product quality and reduce the press filtration demineralizer group of quantity of wastewater effluent.
In order to solve the problems of the technologies described above, press filtration demineralizer group of the present utility model, comprise precoating tank, filter press and strainer, precoating tank is by being connected with the import of a gear pump with the utilidor of ball valve, No. one gear delivery side of pump is connected with the import of filter press by utilidor, the outlet of filter press is connected with one end of a temporary tank by utilidor, the other end of temporary tank is by being connected with the import of No. two gear pumps with the utilidor of ball valve, No. two gear delivery side of pump is connected with the import of strainer by utilidor, the outlet of strainer is connected with heat insulated tank by utilidor.
Described ball valve, utilidor and heat insulated tank are made by stainless steel material.
A described gear pump and No. two gear pumps are high viscosity gear pump.
Described filter press is plate and frame type filter-press, and plate and frame filter press is also connected with a Hydraulic Station, and the below of plate and frame filter press has a slagging-off hopper.
Described strainer is straight plate strainer.
Adopt after above-mentioned structure, due to the precoating tank that each pipeline connects that passes through arranging, filter press, strainer and heat insulated tank, in operating process, organic phase solution in precoating tank is squeezed into filter press, after filter press press filtration, enter temporary tank, after temporary tank stirs to it, enter straight plate strainer and carry out essence filter, the liquid that last press filtration completes enters heat insulated tank, as can be seen here, this filter-pressing device group is not only reduced to the inorganic salt content of finished product below 5ppm, also can reduce washing times in production process, there is desalination speed high, salt residual quantity is low, the feature of practicality simple to operate, thereby improve product quality, save desalination water consumption, reduce quantity of wastewater effluent, reduce cost.
