Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
It should be noted that, unless otherwise clearly defined and limited, term " first ", " second " etc. do not represent order and install, and do not represent the importance of described element yet.
Refer to Fig. 1, electrical dehydrator oily(waste)water reflow treatment system, comprise connect in order second-stage separator crude oil entrance pipe 9, second-stage separator 4, second-stage separator oil phase outlet pipe road 10, the de-topping-up pump 5 of electricity, electricity de-booster pump outlet pipeline 11, electrical dehydrator entrance untreated oil line 12, electrical dehydrator 3 and electrical dehydrator crude exports pipeline 14, electrical dehydrator entrance untreated oil line is connected with electrical dehydrator crude oil entrance by-pass line 13.Also comprise the oily(waste)water return line 8 that one end is connected with electrical dehydrator with electrical dehydrator aqueous phase escape route, the other end is connected with second-stage separator crude oil entrance pipe 9 and the oily(waste)water discharge pipe 15 be connected with electrical dehydrator aqueous phase escape route; Described oily(waste)water return line is provided with the first valve group 1, described oily(waste)water discharge pipe is installed the second valve group 2.
By the oily(waste)water return line 8 that second-stage separator 4 is communicated with described electrical dehydrator aqueous phase escape route with one end, the reaction times that can increase crude oil realizes breaking emulsion and dewatering, and the defective sewage that electrical dehydrator is discharged is transported to second-stage separator by the pressure of electrical dehydrator and again processes.Aqueous phase top hole pressure due to electrical dehydrator 3 is 350 kPas, and the tank body pressure of second-stage separator is 50 kPas, so the high oily(waste)water of the aqueous phase of electrical dehydrator directly can enter second-stage separator with pressure, the flow of electrical dehydrator water-oil interface and aqueous phase outlet oily(waste)water can be controlled by automatic regulating valve.
In the present embodiment, described first valve group comprises the first ball-and-seat 6, first remote control magnetic valve 1-2, the first release valve ball 1-4, is positioned at the first manual ball valve 1-1 of the first remote control magnetic valve side and is positioned at the second manual ball valve 1-3 of the first remote control magnetic valve opposite side.
Described second valve group comprises the second remote control magnetic valve 2-2, the second release valve ball 2-4, be positioned at the 3rd manual ball valve 2-1 of the second remote control magnetic valve side and be positioned at the 4th manual ball valve 2-3 of the second remote control magnetic valve opposite side.Remote control and the switching of manual flow process can be convenient in production waste treating processes by the first valve group and the second valve group.Remote control and the switching of manual flow process can be convenient in production waste treating processes by the first valve group and the second valve group.
Normal operating state: the first manual ball valve 1-1, the second manual ball valve 1-3, the 3rd manual ball valve 2-1, the 4th manual ball valve 2-3 are normally open; First release valve ball 1-4, the second release valve ball 2-4 are normal off status.
When production waste is qualified: the second remote control magnetic valve 2-2 opens, the first remote control magnetic valve 1-2 closes, and makes production waste enter try production.
When production waste is defective: the first remote control magnetic valve 1-2 opens, the second remote control magnetic valve 2-2 closes, and makes production waste enter second-stage separator and again processes.
Note: the principle of valve operation first opens rear pass.
Principle of work of the present utility model is:
When the sewage that the aqueous phase outlet of electrical dehydrator 3 is discharged is defective: the first remote control magnetic valve 1-2 opens, and the second remote control magnetic valve 2-2 closes.Now, underproof sewage enters second-stage separator 4 by the oily(waste)water return line 8 be communicated with electrical dehydrator aqueous phase escape route and proceeds to process, until up to standard.After production water treatment is up to standard, the first remote control magnetic valve is closed, and the second remote control magnetic valve is opened, and try production recovers normal.
