Existing greasy filth dehydration treatment method is generally all transformed into homogeneous state by methods such as mechanical stirring by greasy filth and dewaters, but the dewatering efficiency of the method is generally not high.Traditional city industrial sludge dehydration equipment of having stable political situation is mainly whizzer and folded spiral shell machine, and electrokinetics constantly adds wherein in recent years, has occurred the folded spiral shell machine of electric power dehydration, the equipment such as electroosmotic dewatering whizzer.But these equipment can not be processed this class high viscosity of greasy filth, high oil content, baroque material.With these legacy equipments to greasy filth costs and poor dehydration results, and easy damage equipment.And need to stir mud, tensio-active agent, emulsifying agent etc. are fully mixed with greasy filth, be convenient to the work of the equipment such as whizzer, folded spiral shell machine.But this destroyed original mud structure, solid-liquid mixes homogeneous more, is unfavorable for the generation of electro-osmotic effects.
Summary of the invention
The invention provides a kind of osmosis greasy filth dewatering unit, can directly carry out osmosis processing, simplified prior art processes, reduced equipment and running cost.This device utilizes the principle of osmosis, the greasy filth dehydration equipment that innovative design goes out, and the parameters such as Optimum Regulation concentration of electrolyte, greasy filth pH value, transformer current, it applies oily water separation film of new generation, under the prerequisite of less energy-consumption, fast dewatering.Adopt this method the moisture content of greasy filth can be reduced to minimum 55% by 90% left and right.This method significantly can reduce water content, can improve greasy filth calorific value, ensures the feasibility of next step biological degradation treatment process and burning method.In a lot of fields of sludge treatment, can complete the task that whizzer and folded spiral shell machine can not complete.
For solving above technical problem, the invention provides following technical scheme: a kind of osmosis greasy filth dewatering unit, dewatering unit comprises several current conducting rods, with the negative pole of reserved water vent and the base of carrying landfill sandy soil, current conducting rod is vertically placed and top in negative pole, the bottom of negative pole is landfill sandy soil, and base is provided with several weep holes.
Further, the distance between described current conducting rod and negative pole is adjustable.
Further, described current conducting rod is connected in reactor head, has electrode pre-opened hole on reactor, and current conducting rod relative response device can move up and down.
Further, described reactor is a cubes, is connected in U-shaped base.
Further, described base is that a kind of cross section is the hollow base of U-shaped, the hollow position of greasy filth in base bottom.
Further, described weep hole place connects water discharge pipe, and water discharge pipe is in base bottom or base both sides.
Further, on described water discharge pipe, connect gate valve.
Further, described negative pole is netted.
Further, described current conducting rod is connected in the electrode pre-opened hole of reactor head, between reactor and electrode pre-opened hole for being slidably connected.
Further, described base bottom is provided with concrete support.
This osmosis greasy filth dewatering unit the present invention relates to, utilizes low-voltage DC to produce electric field, has saved a large amount of electric energy compared with high-power whizzer, folded spiral shell machine.Solved the problems such as greasy filth viscosity is high, ventilation property is poor, calorific value is low, have that facility investment is few, good separating effect, turn harm into good, the feature such as economic environmental protection, non-secondary pollution.The popularization of this technology can significantly reduce oil field and the greasy filth processing costs of refinery factory.This technology has effect energetically for reducing topsoil simultaneously, has reduced the discharge in greasy filth treating processes, reduces PM2.5 and PM10.

Embodiment
As shown in Figure 1, osmosis greasy filth dewatering unit comprises several current conducting rods 4, with the negative pole 10 of reserved water vent 11 and the base 2 of carrying landfill sandy soil 8, current conducting rod 4 is vertically placed and top in negative pole 10, the bottom of negative pole is landfill sandy soil 8, base 2 is provided with several weep holes, the hollow base that base 2 is U-shaped for a kind of cross section, the hollow position of greasy filth in base 2 bottoms.Base 2 bottoms are provided with concrete support 3.
Distance between current conducting rod 4 and negative pole is adjustable.Current conducting rod 4 is connected in reactor 1 top, has electrode pre-opened hole on reactor 1, and current conducting rod 4 relative response devices can move up and down.Current conducting rod 4 is connected in the electrode pre-opened hole 12 at reactor 1 top, between reactor 1 and electrode pre-opened hole 12 for being slidably connected.
Reactor 1 is a cubes, is connected in U-shaped base 2.
Weep hole place connects water discharge pipe 6,7, and water discharge pipe 6,7, in base bottom and base both sides, connects gate valve on water discharge pipe 6,7.
Negative pole 10 is netted.
Oil in greasy filth, water, solid matter distribute very inhomogeneous, have the oil granule of shape different sizes, also variant very large oily mass of soil grain, and these materials are all immersed in oil-water mixture.In greasy filth, most pollutent is all water insoluble, so adopt the mechanical means poor effect such as centrifugal, extruding.This dewatering unit utilizes osmosis principle, for the greasy filth feature producing in oil field and refinery factory production process, innovative design osmosis greasy filth dehydration equipment.Low voltage electric field is very little for the solid matter effect in greasy filth, but but has certain effect for moisture.This is because water-soluble positive ion tends to move to negative pole, and negative ion tends to move to positive pole, and this phenomenon makes the moisture in greasy filth active, presents unbound state, produces osmosis.In greasy filth, solid-liquid mixes very inhomogeneously, and this physical properties provides good basis for osmosis.In low voltage electric field, moisture starts to depart from solid-state, and under the driving of gravity, moisture moves to reactor bottom.
Greasy filth electroosmotic dewatering technology is to apply certain volts DS to greasy filth, forms low voltage electric field.Due to the different electrochemical properties of each in greasy filth, utilize in greasy filth granule and water molecules mutually to the phenomenon acceleration liquid movement of contrary polar orientation separate mobile.The object that realizes dehydration under action of gravity and electric field action, the method can be by the moisture content of greasy filth by more than 90% taking off to below 60%.
Embodiment 1
For testing this equipment performance, carry out balancing test comparison (in table 1) with like product.
。
The comparison of two kinds of dehydration equipments of table 1
Result shows, greasy filth water content is reduced to 55.33% by 89.20%, and the parameters such as the stability of equipment, dehydration rate, energy consumption are obviously better than comparative apparatus.Therefore osmosis greasy filth dehydration and drying technology is a kind of emerging, and the technology growing with each passing hour both can be applied to developing direction-biological degradation processing of following greasy filth processing, also can reduce fuel consumption.
Embodiment of the present invention does not form the restriction to the application's scope; every within the spirit and principle of the present invention design, any amendment that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection scope of the present invention.
