Abstract
The invention relates to a device for separating and recovering a working fluid from oxydol sewage oily water, which comprises an oil-water separation tank with a partition in the middle, wherein the upper part of the oil-water separation tank is provided with a sewage inlet valve, and the lower part is provided with an oil-phase outlet valve; the oil-water separation tank is connected with a working fluid inlet valve of a working fluid cleaning and stirring kettle through the oil-phase outlet valve and a pipeline; the working fluid cleaning and stirring kettle is communicated with a buffer tank; and the buffer tank is connected with a vacuum pump. The device can be used in a technique for recovering the working fluid from oxydol production sewage, and the recovered working fluid can be cleaned and reutilized, thereby saving the raw material and lowering the production cost. The device reduces the working fluid content in the sewage middle tank, and lowers the difficulty and pressure for subsequent sewage treatment. The reduction of the working fluid content in the sewage middle tank causes the reduction of the aromatic gas volatile quantity in the working fluid component, thereby improving the surrounding operating environment.
Description
Technical field
The present invention relates to a kind of sewer retrieving arrangement, be specifically related to a kind of device of Separation and Recovery working fluid from hydrogen peroxide blowdown profit.
Background technology
The sewage containing some work liquid produced in Hydrogen Peroxide Production divides acid and alkalescence two kinds, traditional method is collected by arranging independently pipeline, and the sewage after collection carries out acid-base neutralisation and be drawn into a small amount of working fluid by vacuum pump on intermediate pool sewage top layer being reclaimed at intermediate pool (oil trap/pretreatment pool).This method only carries out working fluid recovery on sewage top layer, the work liquid measure of recovery can be caused few because operating inconvenience, cause expensive working fluid loss large, particularly can produce in a large number with the sewage of working fluid when hydrogen peroxide plant fluctuation of service, if reclaim and thoroughly will not waste extensive work liquid not in time, cause follow-up sewage disposal difficulty to strengthen simultaneously, add production cost and environmental protection pressure.If sewage can be made after carrying out oily water separation to remove intermediate pool again, just effectively can reduce the working fluid content in intermediate pool like that, and the high working fluid of concentration can be reclaimed in time, not only reduce Hydrogen Peroxide Production cost, and alleviate the environmental protection pressure of follow-up sewage disposal.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of device of Separation and Recovery working fluid from hydrogen peroxide blowdown profit is provided, can production cost be reduced simultaneously, alleviate sewage disposal difficulty.
The object of the present invention is achieved like this: a kind of device of Separation and Recovery working fluid from hydrogen peroxide blowdown profit, this device comprises the gun barrel being provided with dividing plate in the middle of, gun barrel top is provided with wastewater inlet valve, bottom is provided with oil phase outlet valve, gun barrel is connected with the working fluid imported valve that working fluid cleans stirring tank by oil phase outlet valve and pipeline, working fluid cleaning stirring tank communicates with surge tank, and surge tank is connected with vacuum pump.
Between the working fluid imported valve that described oil phase outlet valve and working fluid clean stirring tank, line strainer is installed.
The wash water valve of the aqueous phase outlet valve of described gun barrel, bypass valve and working fluid cleaning stirring tank is all connected with sewage intermediate pool by pipeline.
The device of Separation and Recovery working fluid from hydrogen peroxide blowdown profit provided by the invention, has following beneficial effect:
1, can be used in the technique of recovery operation liquid from Hydrogen Peroxide Production sewage, the working fluid of recovery can reuse after cleaning, saves starting material, reduces production cost.
2, reduce the working fluid content in sewage intermediate pool, alleviate difficulty and the pressure of follow-up sewage disposal.
3, in sewage intermediate pool, the minimizing of working fluid content makes the aromatic hydrocarbons gaseous volatilization amount in working fluid component reduce, and improves periphery operating environment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Embodiment
Structure of the present invention as shown in Figure 1, a kind of device of Separation and Recovery working fluid from hydrogen peroxide blowdown profit, this device comprises the gun barrel 1 being provided with dividing plate in the middle of, gun barrel 1 top is provided with wastewater inlet valve 7, bottom is provided with oil phase outlet valve 9, gun barrel 1 is connected with the working fluid imported valve 11 that working fluid cleans stirring tank 2 by oil phase outlet valve 9 and pipeline, and working fluid cleaning stirring tank 2 communicates with surge tank 3, and surge tank 3 is connected with vacuum pump 4.
Between the working fluid imported valve 11 that described oil phase outlet valve 9 and working fluid clean stirring tank 2, line strainer 10 is installed.
The wash water valve 12 of the aqueous phase outlet valve 8 of described gun barrel 1, bypass valve 6 and working fluid cleaning stirring tank 2 is all connected with sewage intermediate pool 5 by pipeline.
Principle of work of the present invention is as follows: open wastewater inlet valve 7 in production and make sewage enter gun barrel 1, isolated aqueous phase enters sewage intermediate pool 5 through aqueous phase outlet valve 8, isolated oil phase can be pumped down to working fluid cleaning stirring tank 2 through oil phase outlet valve 9, line strainer 10, working fluid imported valve 11 after tank 3 to be buffered and vacuum pump 4 come into operation, working fluid containing impurity can be transported to oxydol production apparatus and reuse after cleaning, and the sewage produced in cleaning process enters sewage intermediate pool 5 through wash water valve 12.
Sour water and alkaline sewage are respectively equipped with a set of self-contained system, can share surge tank and vacuum pump.
