Abstract
The utility model relates to the defeated coal slurry dewatering system device of a kind of pipe, before the defeated coal slurry dehydration of pipe, coal slurry dilution trap is set, and the defeated coal slurry of pipe is diluted to low concentration and dewaters, and the large or fine granule of the defeated coal slurry of accelerating tube is separated, increases substantially dehydrating effect.This dewatering system device is mainly comprised of pan feeding pipeline, coal slurry dilution trap, dilution trap overflow pipe, screen mesh type Sedimentation centrifugel, concentration basin, concentration basin overflow pipe, sewage treatment plant, filter press, coal yard and connects in certain sequence.Whole apparatus structure is simple, easy to operate.
Description
Technical field
The utility model relates to the defeated coal slurry dewatering system device of a kind of pipe, belongs to solid-liquid two-phase feed separation technical equipment field.
Background technology
The coal slurry weight concentration of long-distance transportation through pipeline is generally 50% to 60%, maximum particle size 3 millimeter, and average grain diameter 0.3 millimeter, wherein the fine grained of 0.045 millimeter of following particle diameter accounts for 20% left and right.At present, coal slurry dehydration equipment mainly adopts centrifuge first most of 0.045 millimeter of above coarse granule to be separated, and then adopts filter press that the fine grained of 0.045 millimeter of following particle diameter is separated.And when adopting centrifuge dewatering, because coal-water fluid concentration is higher, hindered falling phenomenon is serious, the fine grained of particle diameter below causing 0.045 millimeter can not be separated smoothly with the coarse granule of 0.045 millimeter of above particle diameter, totally unfavorable to dewatering, have a strong impact on the dehydrating effect of centrifuge, finally cause the moisture of dehydrating prods too high.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of pipe defeated coal slurry dewatering system device, after the defeated coal slurry of pipe is diluted to low concentration, dewaters again, separated at dehydration preacceleration large or fine granule, increases substantially dehydrating effect.
For achieving the above object, the utility model is by the following technical solutions:
The defeated coal slurry dewatering system device of a kind of pipe is mainly by pan feeding pipeline, coal slurry dilution trap, dilution trap overflow pipe, screen mesh type Sedimentation centrifugel, concentration basin, concentration basin overflow pipe, sewage treatment plant, filter press, coal yard forms, described pan feeding pipeline is connected with described coal slurry dilution trap, the overflow of described coal slurry dilution trap enters described concentration basin by described dilution trap overflow pipe, the underflow of described coal slurry dilution trap enters described screen mesh type Sedimentation centrifugel, the filtrate of described screen mesh type Sedimentation centrifugel enters into described concentration basin, the coal slime product of described screen mesh type Sedimentation centrifugel is delivered to described coal yard by conveyer, a described concentration basin overflow part enters described coal slurry dilution trap by described concentration basin overflow pipe, another part enters described sewage treatment plant, described concentration basin underflow enters described filter press, described cake of filter-press product is delivered to described coal yard by conveyer, the filtrate of described filter press enters described concentration basin by pipeline.
Further, described pan feeding pipeline and described concentration basin overflow pipe are arranged near the center of described coal slurry dilution trap.
This manages the beneficial effect of defeated coal slurry dewatering system device: before the defeated coal slurry dehydration of pipe, coal slurry dilution trap is set, the defeated coal slurry of pipe is diluted to low concentration and dewaters, the large or fine granule of the defeated coal slurry of accelerating tube is separated, increases substantially dehydrating effect.Whole apparatus structure is simple, easy to operate.
