The sump oil treatment unit
Technical field:
The utility model relates to oil recovery field, oil field used sump oil recycling equipment, especially sump oil treatment unit.
Background technology:
Along with deepening continuously of oil-field development, the environmental protection work in oil field is also more and more important.In order to protect environment, need handle the sump oil that produces in the oil recovery process.And present sump oil treatment unit since reasons in structure to exist separating power poor, the problem that treatment capacity is little, sump oil is handled do not reached index, the sump oil of not handling simultaneously is through storing for a long time, and oxidation forms more reluctant ageing oil, can only do and bury processing.Not only take a large amount of soils, cause the huge wasting of resources, also cause great pollution to environment.
The utility model content:
In order to solve existing sump oil treatment unit separating power difference and the little problem of treatment capacity, the utility model provides a kind of sump oil treatment unit, and this sump oil treatment unit has separating power and reaches the big characteristics of treatment capacity by force.
The technical solution of the utility model is: this sump oil treatment unit comprises contaminated-oil basin, contaminated-oil basin passes through pipeline, valve and pump are connected with strainer, strainer is connected with surge tank by pipeline and valve, surge tank passes through pipeline, valve and pump are connected with one section interchanger upper end, pipeline is passed through in one section interchanger and two sections interchanger upper ends, valve and pump are connected with electric power hot oil furnace upper end, electric power hot oil furnace lower end is connected with one section interchanger and two sections interchanger lower ends respectively by pipeline and valve, one section another lower end of interchanger is connected with the two phase separator opening for feed by pipeline and valve, the two phase separator discharge port is connected with two sections interchanger upper ends by pipeline, two sections another lower ends of interchanger are connected with the triphase separator opening for feed by pipeline, be connected with dosing tank by pipeline and valve on the pipeline between one section interchanger and two phase separator, dosing tank is built-in with agitator, the impurity outlet is arranged on the two phase separator, oil is arranged respectively on the triphase separator, water and impurity outlet.
The utlity model has following beneficial effect: this sump oil treatment unit is owing to take such scheme, because of between one section interchanger and two sections interchanger, being communicated with two phase separator, be communicated with triphase separator two sections interchanger lower ends, and two phase separator and triphase separator rotating speed height, thereby the enhancing separating power, making separating factor be up to every gram 4000 changes.Can move continuously simultaneously, thereby improve treatment capacity because of two phase separator and triphase separator.To have separating power strong for this sump oil treatment unit thus, the characteristics that treatment capacity is big.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-contaminated-oil basin among the figure, 2-strainer, 3-surge tank, one section interchanger of 4-, two sections interchanger of 5-, 6-electric power hot oil furnace, 7-two phase separator, 8-triphase separator, 9-dosing tank.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this sump oil treatment unit comprises contaminated-oil basin 1, contaminated-oil basin 1 passes through pipeline, valve and pump are connected with strainer 2, strainer 2 is connected with surge tank 3 by pipeline and valve, surge tank 3 passes through pipeline, valve and pump are connected with one section interchanger 4 upper end, pipeline is passed through in one section interchanger 4 and two sections interchanger 5 upper ends, valve and pump are connected with electric power hot oil furnace 6 upper ends, electric power hot oil furnace 6 lower ends are connected with one section interchanger 4 and two sections interchanger 5 lower ends respectively by pipeline and valve, one section interchanger 4 another lower end is connected with two phase separator 7 opening for feeds by pipeline and valve, two phase separator 7 discharge ports are connected with two sections interchanger 5 upper ends by pipeline, two sections interchanger 5 another lower ends are connected with triphase separator 8 opening for feeds by pipeline, be connected with dosing tank 9 by pipeline and valve on 7 pipelines of one section interchanger 4 and two phase separator, dosing tank 9 is built-in with agitator, the impurity outlet is arranged on the two phase separator 7, oil is arranged respectively on the triphase separator 8, water and impurity outlet.
During actual the use, sump oil in the contaminated-oil basin 1 enters surge tank 3 by pump and strainer 2, in surge tank 3, once heat through entering in one section interchanger 4 after the buffering sedimentation, enter after the heating in the OFB type two phase separator 7 and carry out flash trapping stage, enter second-heating in two sections interchanger 5 through the You Heshui behind two phase separator 7 flash trapping stage, enter the last separation of triphase separator 8 through the You Heshui after the second-heating of two sections interchanger 5, oil, water and impurity are separated.Because of being communicated with two phase separator 7 at one section interchanger 4 and two sections 5 on interchanger, sump oil has been carried out initial gross separation, further separate by triphase separator 8 through two sections interchanger, 5 heating backs again, and the rotating speed height of two phase separator 7 and triphase separator 8, thereby enhancing separating power, making separating factor be up to every gram 4000 changes, and can move continuously because of two phase separator 7 and triphase separator 8 simultaneously, thereby improve treatment capacity.This sump oil treatment unit has separating power and reaches the big characteristics of treatment capacity by force thus.
