The present invention utilizes the electrophoretic characteristic of water or oil by increase electric separating plate frame in existing filter press dehydration equipment, makes water molecules or oil molecule to movable cathode, and by filter screen, has realized the acceleration dehydration of mud.Principle of the present invention is ripe, technology is reliable, suit large area to popularize, utilize direct current separating plate frame provided by the present invention will make the higher sludge cake of existing plate-and-frame filter press output moisture (oil-containing) amount finish further dehydration, reach the target value of sludge cake 50% water content.
Summary of the invention
The present invention seeks to: by the direct current separating plate frame of the present invention's proposition, the working efficiency of existing plate-and-frame filter press will be improved, reduce the water content of sludge cake, realize the target value of sludge cake 50% water content, isolate simultaneously other and utilize the mechanical force principle equipment can't isolated oil.
The present invention adopts following technical scheme to realize, comprises the steps:
1) on the basis of existing conventional plate-and-frame filter press, the male or female metal frame that joins with the dc power anode power supply is installed in left cover 4 positions;
2) on the basis of existing conventional plate-and-frame filter press, negative electrode or the anode metal frame (the metal frame polarity of installing with left cover is opposite) that joins with the dc power cathode power supply is installed in right cover plate 6 positions;
3) on the basis of existing conventional plate-and-frame filter press, at filter plate 5 and 11 of filter frames the filter cloth 12 with fine permeable or saturating oily characteristic and insulation characterisitic is installed, and this filter cloth is installed in filter frame 11 places near right cover plate 6 sides;
4) during equipment work, by the general electronic technology of routine, regulate output voltage and the electric current of direct supply, the voltage of direct supply output is maintained between the 20v to 100v all the time, electric current maintains between the 0A to 2000A, guarantees that the liquid electrophoresis is normal in the mud;
5) by having the sludge pressing control device of plate-and-frame filter press now, utilize the spacing between conventional hydraulic pressure or mechanical means adjusting filter frame and the pressing plate filter screen, on the basis of passing through mechanical pressure filtering water or oil of routine, the liquid electrophoresis that has superposeed simultaneously and utilized direct current to produce, accelerate water or oil in the filtering sludge cake, and reduce the water content in the sludge cake.
The present invention is by being installed in the direct current separating plate frame on the existing plate-and-frame filter press, regulate direct current received current and voltage on it, guarantee voltage stabilization between anode metal frame and the cathodic metal frame, the liquid electrophoresis is working properly, but the squeezing effect of Effective Raise sludge dewatering, not only can reach the target value of sludge cake 50% water content, and can isolate the oil in the not segregative mud of other device for dehydrating sladge waste.
