Abstract

The utility model discloses a device for separating and recycling a working solution from hydrogen peroxide drainage oil. The device comprises an oil-water separation tank with a partitioning plate in the middle, wherein a sewage inlet valve is arranged at the upper part of the oil-water separation tank; an oil phase outlet valve is arranged at the lower part of the oil-water separation tank; the oil-water separation tank is connected with a working solution inlet valve of a working solution washing stirring kettle through the oil phase outlet valve and a pipeline; the working solution washing stirring kettle is communicated with a buffer tank; the buffer tank is connected with a vacuum pump. The device can be used in a process for recycling the working solution from hydrogen peroxide production sewage, and the recycled working solution can be washed and reused, so that the raw material is saved, the production cost is lowered, the content of the working solution in a sewage middle pool is reduced, and the difficulty and the pressure in later sewage treatment are alleviated; as the content of the working solution in the sewage middle pool is reduced, the volatilization of an arene gas in the working solution is reduced, and the ambient operation environment is improved.

Description

The device of Separation and Recovery working fluid from hydrogen peroxide blowdown profit
Technical field
The utility model relates to a kind of sewer retrieving arrangement, be specifically related to a kind of from hydrogen peroxide blowdown profit the device of Separation and Recovery working fluid.
Background technology
The sewage that contains some work liquid that hydrogen peroxide produces in producing divides acidity and two kinds of alkalescence, traditional method is to collect by independently pipeline is set, and the sewage after collection carries out acid-base neutralisation and can be drawn into a small amount of working fluid on intermediate pool sewage top layer by vacuum pump being reclaimed at intermediate pool (oil trap/pretreatment pool).This method is only carried out working fluid recovery on sewage top layer, can cause the work liquid measure of recovery few because operating inconvenience, cause expensive working fluid loss large, particularly in the time of hydrogen peroxide plant fluctuation of service, can produce the sewage with working fluid in a large number, thoroughly will not waste not in time extensive work liquid if reclaimed, cause follow-up sewage disposal difficulty to strengthen simultaneously, increased production cost and environmental protection pressure.If can make sewage remove again intermediate pool after carrying out oily water separation, just can effectively reduce like that the working fluid content in intermediate pool, and can reclaim in time the working fluid that concentration is high, not only reduce hydrogen peroxide production cost, and alleviate the environmental protection pressure of follow-up sewage disposal.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of from hydrogen peroxide blowdown profit the device of Separation and Recovery working fluid, can reduce production costs simultaneously, alleviate sewage disposal difficulty.
The purpose of this utility model be achieved in that a kind of from hydrogen peroxide blowdown profit the device of Separation and Recovery working fluid, this device comprises the gun barrel that is provided with dividing plate in the middle of, gun barrel top is provided with sewage imported 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 cleans stirring tank and communicates with surge tank, and surge tank is connected with vacuum pump.
Between the working fluid imported valve of described oil phase outlet valve and working fluid cleaning stirring tank, line strainer is installed.
The wash water valve that water outlet valve, bypass valve and the working fluid of described gun barrel cleans stirring tank is all connected with sewage intermediate pool by pipeline.
The device of Separation and Recovery working fluid from hydrogen peroxide blowdown profit that the utility model provides, has following beneficial effect:
1, can be used in the technique of recovery operation liquid from hydrogen peroxide production waste, the working fluid of recovery can reuse after cleaning, and has saved starting material, has reduced production cost.
2, reduce the working fluid content in sewage intermediate pool, alleviated difficulty and the pressure of follow-up sewage disposal.
3, in sewage intermediate pool, working fluid content reduces the aromatic hydrocarbons gaseous volatilization amount reduction making in working fluid component, has improved periphery operating environment.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
Structure of the present utility model as shown in Figure 1, a kind of from hydrogen peroxide blowdown profit the device of Separation and Recovery working fluid, this device comprises the gun barrel 1 that is provided with dividing plate in the middle of, gun barrel 1 top is provided with sewage imported 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 cleans stirring tank 2 and communicates with surge tank 3, and surge tank 3 is connected with vacuum pump 4.
Between the working fluid imported valve 11 of described oil phase outlet valve 9 and working fluid cleaning stirring tank 2, line strainer 10 is installed.
The wash water valve 12 that water outlet valve 8, bypass valve 6 and the working fluid of described gun barrel 1 cleans stirring tank 2 is all connected with sewage intermediate pool 5 by pipeline.
Principle of work of the present utility model is as follows: in production, open sewage imported valve 7 and make sewage enter gun barrel 1, isolated water enters sewage intermediate pool 5 through water outlet valve 8, after surge tank 3 and vacuum pump 4 come into operation, isolated oil phase can be pumped down to working fluid through oil phase outlet valve 9, line strainer 10, working fluid imported valve 11 and clean stirring tank 2, the working fluid that contains impurity can be transported to oxydol production apparatus and reuse after cleaning, and the sewage producing in cleaning process enters sewage intermediate pool 5 through wash water valve 12.
The a set of self-contained system of the each outfit of sour water and alkaline sewage, can share surge tank and vacuum pump.
