Description
Technical field
The utility model relates to oil separating purification techniques in the water, be primarily aimed at the oil-water mixture of industrial circle, especially with the high-temperature steam condensed water oil-water mixture of main medium, by separating measure to oil-water mixture, water is purified, can utilize once more, realize the double effects that water saving is energy-conservation again.
Background technology
China is water resources and energy starved country, but aspect the utilization ratio and water-saving rate of water, compares the big gap of also existence with international most advanced level.Have serious waste in production and sphere of life, wherein the ton profit consumption of part petroleum chemical enterprise is still more than the index that national requirements reaches.
Petroleum chemical enterprise is the mainstay industry of country, also is one of main consumer of water resources, and its process water and steam condenses just account for very big ratio.Yet, for many years,, cause being difficult to recycling because the oleaginousness in process water and the condensed water can't be up to standard, can only be toward the sewer line discharging, therefore, the recycling of oil-containing water is a very stubborn problem always.And, because steam condenses directly reuses in the back boiler, can only demote and use or discharging, heat energy wherein also is wasted, and loses very surprising.
In fact, condensed water after the purification can be used as the de-salted water through preheating, do a vapour directly for waste heat boiler deoxygenation case and use (or power station boiler), can reach the recycling of three aspects like this, that is: " water resources taxes+desalination expense+remaining calorific value ", account for 25% of steam total heat value greatly, it serves to show that recycle value is very considerable.
The main difficulty of isolating oily substance from condensed water in high temperature has: the one, and the condensing water temperature height, often about 85～110 ℃, therefore wherein contained oily substance many places are difficult to remove at emulsified state; The 2nd, the media of oil removing is saturated bigger with the regenerated difficulty, and the good technology of a lot of oil removings all can't be carried out the industrialization long-time running because of all kinds of problems.
Common deoiling method all exists deficiency to some extent at present, can not really address this problem.For example activated carbon method relies on the adsorptive power oil removing, but is easy to saturated poisoning, the external roasting of palpus, very trouble during regeneration; If use the steam internal regeneration, energy consumption is too high, and the gac loss is big.
Pay attention to water saving and energy-conservation today in the whole society; if after butyraceous process waters of these a large amount of dischargings and steam condenses done the oil removing purifying treatment; realize utilizing once more; both saved great amount of water resources; reclaimed residue heat energy again; also protected environment, existing economic implications really, the good project of social effect is also arranged.
The utility model content
The technical problems to be solved in the utility model is: a kind of process water and high-temperature steam condensed water oil removal plant are provided, can make that oil separates effectively in the water, can reach the purpose that recycles once more, thereby improve the defective of removing oil purification of oil in the above-mentioned known water.

Embodiment
Following conjunction with figs. and specific embodiment are described in further detail embodiment of the present utility model.
The utility model proposes oil separating refining plant in a kind of water, it has a tank body, and this device also comprises: at least one oil-containing water import, and it is located at the bottom of tank body, through pipe connection oil-containing water recovery system; At least one resin bed, it is located at tank interior, and oil-containing water enters from its underpart, and portion discharges from it; The outlet of at least one clean water, it is located at the top of resin bed, through pipe connection to the clean water delivery system; At least one main oil discharge outlet, it is located at the top of tank body, discharges delivery system through pipe connection to waste oil.
As shown in Figure 1, be the synoptic diagram of a specific embodiment of the present utility model.Among this embodiment, the tank base of separating of oil refining plant is provided with an oil-containing water import 6 in the water, is used for the introducing of oil-containing water; Resin bed 1 is located at the top of oil-containing water import 6, is positioned at the position, middle and lower part of tank body, and this resin bed 1 adopts high temperature resistant oleophilic resin, with to the carrying out breakdown of emulsion, enrichment, peel off of the oil in the oil-containing water, forms oil droplet gradually.This process continuously circulation is carried out, autoregeneration, the profit processing of also needn't lowering the temperature; The top of resin bed 1 is provided with a current accelerator 7, and current accelerator 7 roughly is taper, is located at the resin bed top, is used to improve the speed of current, makes it to possess certain kinetic energy; A plurality of degreasing tanks 2, ring-type is connected in the inwall of tank body, and layering (present embodiment is three layers, but is not limited thereto) is placed at the top of resin bed 1 and the outside of current accelerator 7, in the profit that rises by resin bed 1 back, catch oil droplet, and isolated oily substance is collected storage.In the present embodiment, the outlet of current accelerator 7 is higher than described clean water outlet 3, is beneficial to reduce the oleaginousness in the clean water of being got rid of.
The degreasing tank ring-type that this utility model adopts is connected in the inwall of this tank body, and is distributed in the top of this resin bed, and this tank body is provided with auxiliary oil discharge outlet 5 and communicates with degreasing tank 2.As shown in Figure 2, in the present embodiment, degreasing tank 2 comprises the annulus 21 that forms the oil-containing water passage and connects this inner tank wall and the separating part 22 of this annulus 21, this separating part 22 and inwall and corresponding annulus 21 constitute the annular groove 20 that stores oily substances, auxiliary oil discharge outlet 5 is arranged at the zone on this separating part 22, described clean water outlet 3 zones that are arranged under this separating part 22, and auxiliary oil discharge outlet 5 is provided with valve and communicates with oil exit pipe 4.
