Description
Technical field
The utility model is the airtight automatic floating oil device of a kind of oily water treatment.The processing and the tubing system technical field that relate to sewage.
Background technology
Oil product through pipelines always has oily(waste)water and produces in course of conveying, particularly pontoon-deck-tank needed to clean after operation for some time, so will produce a large amount of oily(waste)waters.These oily(waste)waters one are can not directly discharge from the angle of environmental protection, the 2nd, do not handle the waste that discharging also is a kind of resource.So the pipeline oil transportation industry is being carried out the work of treatment of oily(waste)water always.Particularly to the cleaning of pontoon-deck-tank, because of general pontoon-deck-tank volume is bigger, the water yield that cleaning gets up to need is very big, and as all using clean water, that will be the very big waste of water resources.So generally be that rinse water recycles, this just need do certain processing to the water that rinse water is got off, and is used for cleaning again.At present, employing be that floating oil is handled, but the floating oil treatment unit is too simple, is to carry out floating oil with open groove, the oil slick of the face that floats on the water is manually received in oil groove simply.Therefore, labor intensive not only, and in the floating oil process, oil slick water ratio height can not reach standard, pressing that the standard-required oil slick is moisture must not be greater than 3%, in fact will be much larger than this number.So, being used for cleaning pontoon-deck-tank again, obviously is a kind of waste.
The utility model content
The airtight automatic floating oil device of oily water treatment that the purpose of this utility model is a kind of saving of labor of design, efficient is high.
Formation of the present utility model as shown in Figure 1, it by oily water separation sled 2, thermal insulation layer 3, liquid-inlet pipe 1, collection tank 4, corrugated plate packing 5, swash plate filler 7, pressure equilibrium take over 8, oil slick reclaim take over 9, fluid level measuring gauge 11, liquid level control topworks 12, pressure-controlling accommodometer 13, variable valve 14, surge pump 15, impeller pump 16, ball valve 17, oil slick header 18, pressure unit 19 and liquid discharge pipe 20 form.2 left sides (with direction shown in Figure 1) are prized in the airtight oily water separation that is surrounded by thermal insulation layer 3 outward liquid-inlet pipe 1,2 internal upper parts are prized in oily water separation has the oil slick under collection tank 4, the groove to reclaim adapter 9 and oil slick header 18, the pressure unit 19 that the bottom has liquid-inlet pipe 1, corrugated plate packing 5, swash plate filler 7, liquid discharge pipe 20, anchor 10 from left to right successively and installs down in the oily water separation sled 2, liquid discharge pipe 20 connects valve 17, impeller pump 16, variable valve 14 successively by pipeline, or can be connected in series tensimeter, valve, tensimeter more successively between impeller pump 16 and variable valve 14; And pressure unit 19 outputs are connected to the control end of variable valve 14 behind pressure-controlling accommodometer 13; Meet liquid level control topworks 12 with collection tank 4 horizontally disposed fluid level measuring gauge 11 outputs, by the start and stop of liquid level control topworks 12 control surge pumps 15 (volumetric pump).
Wherein corrugated plate packing 5 is the stainless steel wave card, and effect is a current stabilization, and this is provided with when big at treatment capacity.Distance between the interior top of the top of rationally definite corrugated plate packing 5 filled bands and jar is unlikely the fast oil droplet of ascent rate and accumulates in top, and waved plate can not form resistance to last oil slick to flowing of oil outlet.General this distance is controlled between 300～500mm.
The structure of swash plate filler 7 as shown in Figure 3, it is multilayer " V " the type swash plate structure of being made by stainless steel plate, rationally determines gap between swash plate filled band swash plate and the swash plate, just can solve oil slick and be trapped in the swash plate obstruction oil slick to the flow problem of oil outlet.The gap is generally 5～20mm between swash plate and the swash plate.
Fluid level measuring gauge 11 is installed in the collection tank 4, the output of fluid level measuring gauge 11 meets liquid level control topworks 12, by the variation outgoing signal of liquid level, the signal amplification is made switch motion, the start and stop of control surge pump 15, thus the oil extraction of realization oil slick is controlled automatically.
After oily(waste)water entered oily water separation sled, the particle diameter of oil floated to liquid level in that the oil droplet more than 100 microns is very fast in the oily(waste)water, and remaining will be by the filler coarse less than 100 microns oil droplet, thereby has improved ascent rate.When the pasta of come-up is higher than the collection tank 4 that is arranged in the sled, oil slick will lean on the effect of gravity to flow into collection tank 4, when pasta in the collection tank 4 reaches the setting liquid level, automatic control system is started working, the surge pump 15 that promptly is arranged on jar outer sled brings into operation, and oil slick is transferred to the appointment storage tank through collection tank 4, oil slick header 18 and surge pump 15.Another Controlling System is responsible for controlling constant pressure, when level change, pressure unit 19 is obtained signal, and pass the signal to pressure-controlling accommodometer 13, pressure-controlling accommodometer 13 compares the force value of this pressure signal value and setting, passes through the flow of the effect controlled liq of variable valve 14 afterwards, thereby the liquid level in the container is changed in allowed band, with what guarantee to enter collection tank 4 is oil slick fully, and water is blocked in the outside.Therefore the acting in conjunction of two Controlling System has realized the automatic airtight floating oil.
As seen, the utility model has overcome not only that corrugated plate packing 5 and swash plate filler 7 exist last oil slick easily is trapped in to the mobile formation resistance of oil outlet and oil slick hinders oil slick to oil outlet mobile problem in the swash plate, the accessible come-up of oil slick is also accessible mobile to oil outlet, has improved the oily water separation rate; Can regulate the recovery of oil slick and the discharge for the treatment of water automatically, save artificial; And the processing oily(waste)water of flow greatly, use for cleaning pontoon-deck-tank recirculated water.
