Electro-endosmosis type dehydrator

An electro-endosmosis type dehydrator in which voltage is applied across a rotary drum having electrodes on the cylindrical wall thereof and a press belt confronted through a sludge passageway with the cylindrical wall of said rotary drum, and water contained in sludge supplied to said sludge passageway is collected on the side of said press belt and discharged therefrom, wherein said electrodes on said rotary drum are a plurality of wire electrodes which are arranged on the cylindrical wall of said rotary drum in such a manner that said wire electrodes are in parallel with one another to form degasifying slits therebetween, through which gas generated from said sludge in said sludge passageway is discharged therefrom, and wherein said rotary drum includes an electrode assembly, which is divided into a plurality of arcuate blocks, said arcuate blocks being mounted on the cylindrical wall of said rotary drum.

An electro-endosmosis type dehydrator in which voltage is applied across a rotary drum having electrodes on the cylindrical wall thereof and a press belt confronted through a sludge passageway with the cylindrical wall of said rotary drum, and water contained in sludge supplied to said sludge passageway is collected on the side of said press belt and discharged therefrom, wherein said electrodes on said rotary drum are a plurality of wire electrodes which are arranged on the cylindrical wall of said rotary drum in such a manner that said wire electrodes are in parallel with one another to form degasifying slits therebetween, through which gas generated from said sludge in said sludge passageway is discharged therefrom, and wherein washing means for jetting washing water to the space under an electrode assembly is arranged on the cylindrical wall of said rotary drum, to remove sludge therefrom.

An electro-endosmosis type dehydrator including a rotary drum in which a DC voltage is applied across an anode having an electrode plate and a cathode confronted with each other through a space as a sludge passageway, and water contained in sludge supplied to said space is collected on said cathode side by electro-endosmosis and discharged out of the system, wherein said anode is contacted with said sludge directly, dewaterifying/degasifying holes are scatteringly formed through said electrode plate, and a filtrating material is tightly put on the back surface side of said electrode plate and between said rotary drum and said electrode plate to cover said dewaterifying/degasifying holes.

An electro-endosmosis type dehydrator in which DC voltage is applied across an anode having an electrode plate and a cathode confronted with each other through a space as a sludge passageway, and water contained in sludge supplied to said space is collected on the side of said cathode by electroendosmosis and discharged out of the system, wherein said anode is contacted with said sludge directly, dewaterifying/degasifying holes are scatteringly formed through said electrode plate, and each of said dewaterifying/degasifying holes is filled with a filtrating material.

An electro-endosmosis type dehydrator in which DC voltage is applied across an anode having an electrode plate and a cathode confronted with each other through a space as a sludge passageway, and water contained in sludge supplied to said space is collected on the side of said cathode by electroendosmosis and discharged out of the system, wherein said anode is contacted with said sludge directly, and band-like filtrating materials with their one-side ends drawn outside and having capillary tube functions are scatteringly arranged on the surface of said electrode plate of said electrode plate on the side thereof contacting with said sludge.

An electro-endosmosis type dehydrator in which voltage is applied across a rotary drum having electrodes on the cylindrical wall thereof and a press belt confronted through a sludge passageway with the cylindrical wall of said rotary drum, and water contained in sludge supplied to said sludge passageway is collected on the side of said press belt and discharged therefrom, wherein said electrodes on said rotary drum are a plurality of wire electrodes which are arranged on the cylindrical wall of said rotary drum in such a manner that said Wire electrodes are in parallel with one another to form degasifying slits therebetween, through which gas generated from said sludge in said sludge passageway is discharged therefrom, and wherein said electrodes are radially spaced from said cylindrical wall of said rotary drum for forming a degasifying passage and parallely spaced from each other for preventing said sludge from entering said degasifying passage.

An electro-endosmosis type dehydrator in which voltage is applied across a rotary drum having electrodes on the cylindrical wall thereof and a press belt confronted through a sludge passageway with the cylindrical wall of said rotary drum, and water contained in sludge supplied to said sludge passageway is collected on the side of said press belt and discharged therefrom, wherein said electrodes on said rotary drum are a plurality of wire electrodes which are arranged on the cylindrical wall of said rotary drum in such a manner that said wire electrodes are in parallel with one another to form degasifying slits therebetween, through which gas generated from said sludge in said sludge passageway is discharged therefrom, and wherein each of said electrodes extends in a circumferential direction with respect to said rotary drum.
