Abstract

The utility model discloses a novel oil-water separator, comprising an oil filter and an oil remover which are arranged on a base; the oil filter comprises a steel wire mesh which is arranged on a supporting plate at the central part of the oil filter; the steel wire mesh is used for replacing the traditional quartz sand filler, thus being capable of effectively improving the oil removal rate, being convenient to back washing and leading the post-treatment to effectively reduce load; an electric heater of the oil remover can effectively reduce the viscosity of water in low-temperature areas and effectively improve the efficiency of oil-water separation; the oil content of a water outlet is lower than 3mg/L; a coarse-grained inclined tube leads the flowing path of wastewater to be increased, prolongs the stopping time of water, leads oil droplets to have more upward floating time, continuously changes the flow direction in the slow flowing process, increases collision of oil droplets and gathering chance and leads the oil droplets to enlarge and to float upward to an upper oil-collecting cavity. The novel oil-water separator has compact structure and small occupied area and the skid mounted structure of the equipment is convenient to transport and install.

Description

A kind of novel oil water separator

Technical field

The utility model relates to a kind of separator, a kind of novel oil water separator of concrete water treatment oily waste water.

Background technology

In the processing of oily waste water, oil interceptor is widely used.But traditional parallel flow intercepter floor space is wide, construction investment is big, in order to reach better treatment effect, have to adopt the increase time of staying, adding means such as chemical agent is assisted, this has increased cost of sewage disposal to a certain extent, and water has been carried out polluting once more in adding the process of medicament, has increased the intractability of sewage.Traditional oil interceptor is poor to the adaptive capacity of sewage, and the source of oil-polluted water is many-sided, thereby it has complexity, characteristics such as polytropy, and the very difficult above-mentioned feature that adapts to oily waste water of general oil interceptor.Under sewage quality change to float very big situation, just might cause the overwork of subsequent handling like this, the treatment and purification that these have all influenced oil-polluted water to a certain extent influences the whole structure of water treatment technology.

Summary of the invention

Goal of the invention: the purpose of this utility model is to provide a kind of oil-water separation and excellent in efficiency, saves processing cost, efficient convenient and practical novel oily waste water separator.

Technical scheme: a kind of novel oil water separator, it comprises oil strainer and oil expeller, and oil strainer and oil expeller are installed on the base, and described oil strainer comprises steel wire, and steel wire is arranged on the support plate at oil strainer middle part.

Wherein, at the filter that is provided with of oil expeller inner bottom part

Wherein, described filter comprises coarse filler and inclined tube, and the coarse filler is arranged on the inclined tube top, and the coarse filler and the inclined tube that are provided with in oil expeller can make small oil droplet increase, and improve separating effect.

Wherein, electric heater is installed, can be effectively reduced the viscosity of low temp area water, effectively improve the effect of water-oil separating at the top of oil expeller.

Oil-polluted water enters from water intaking valve and carries out preliminary treatment the oil strainer, and sewage filters through the steel wire filler; Water intaking valve by oil expeller enters into oil expeller and further handles then.On the support plate at oil expeller middle part, be provided with the coarse inclined tube; it is coalescent that small suspended oil in the sewage drops in coarse inclined tube surface; the formation come-up that comes off after than larger oil droplet; to the collection chamber collection at oil expeller top; draining valve through oil expeller is discharged, and the water after the water-oil separating is then discharged by the delivery port of oil expeller.

Beneficial effect: (1) replaces traditional quartz sand filler can effectively improve oil removing rate with steel wire, and makes things convenient for backwash, makes subsequent treatment effectively reduce load.(2) electric heater on the oil expeller can effectively reduce the viscosity of low temp area water, effectively improves the efficient of water-oil separating, and the delivery port oil content is lower than 3mg/L.(3) the coarse inclined tube increases the flow path of waste water, prolongs the time of staying of water, makes oil droplet that more abundant floating interval of floating dock be arranged; and in flow process slowly; constantly change flow direction, increase the collision of oil droplet, also poly-chance, make oil droplet grow up and float to the top collection chamber.(4) compact conformation of the present utility model, floor space is few, the convenient transportation of the skid structure of equipment, installation.(5) the utility model is corrosion-resistant, and long service life can backwash, and maintenance is cleaned convenient.

Fig. 2 is the oil strainer inner stuffing structural representation among Fig. 1.

Fig. 3 is the oil expeller inner stuffing structural representation among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

Shown in Fig. 1,2 and 3, a kind of novel oil water separator of the present utility model comprises oil strainer 1 and oil expeller 2, and oil strainer 1 and oil expeller 2 are installed on the base 3, and the two is connected in series, the convenient transportation of this skid structure, installation.

Oil strainer 1 comprises oil strainer water inlet 11, oil strainer delivery port 12 and steel wire 13, and steel wire 13 is arranged on the support plate at oil strainer 1 middle part, replaces traditional quartz sand filler can effectively improve oil removing rate with steel wire 13.Oil-polluted water enters in the oil strainer 1 from oil strainer water inlet 11, filters the back through steel wire 13 and discharges from oil strainer delivery port 12.

Oil expeller 2 comprises oil expeller water inlet 21, collection chamber 22, coarse inclined tube 23, oil drain out 24, electric heater 25, fills mouth 26 and oil expeller delivery port 27.Oil expeller water inlet 21 is communicated with oil strainer delivery port 12 by pipeline, is entered in the oil expeller 2 through oil expeller water inlet 21 by oil strainer delivery port 12 through the waste water after oil strainer 1 preliminary the filtration.Oil expeller 2 tops have 22, two collection chambers 22 of two collection chambers to be communicated with by pipeline, and pipe end is an oil drain out 23.The top of oil expeller 2 also is provided with two electric heaters 24, and electric heater 24 can effectively reduce the viscosity of low temp area water, effectively improves the effect of water-oil separating.Be provided with filter 25 at oil expeller 2 inner bottom parts, filter 25 bag coarse filler and inclined tubes, the coarse filler is laid on the inclined tube top, and inclined tube is installed in oil expeller 2 bottoms.The coarse filler adopts hydrophobic oleophylic ceramics filling, surperficial many micropores of ceramics filling, and inner mesh is crisscross, has very strong suction-operated.The water that has filtered enters the drainage pipeline that communicates with the coarse filler, and drainage pipeline passes from filling mouth 26.Oil expeller 2 is provided with three and fills mouth 26, has three drainage pipelines to stretch out from filling mouth 26, is pooled to the main sewer road then, discharges through the oil expeller delivery port 27 in main sewer road.The main sewer road other end is the backwash mouth, after filtration a period of time, carries out backwash, breaks through the impurity of bonding on the filter device 25, guarantees filter effect.The inclined tube of breaking through filter device 25 make waste water flow path increase, prolong the time of staying of water, make oil droplet that more abundant floating interval of floating dock be arranged, and in flow process slowly, constantly change flow direction, increase the collision of oil droplet, also poly-chance, make oil droplet grow up and float to top collection chamber 22.
