Technical field
The utility model relates to chemical equipment technical fields, specifically, being related to a kind of based on anthraquinone hydrogen peroxide
Production equipment and extraction process unit for constructing the production equipment.
Background technique
Currently, anthraquinone technique is most important hydrogen peroxide manufacture technique.In process of production, working solution is walked in hydrogenation
Hydrogenated processing obtains hydride in rapid, and hydride is oxidation-treated in oxidation step to obtain the oxidation solution containing hydrogen peroxide,
Oxidation solution is used pure water to extract in extraction step, obtains extract liquor and raffinate, the raffinate be containing a small amount of water with
The working solution of hydrogen peroxide.
Common extraction tower carries out disclosing one kind in extraction processing, such as the patent document of Publication No. CN103803504A
Extract tower structure comprising top is equipped with the tower casing of raffinate outlet.Due in extraction process, it may appear that " Water-In-Oil " phenomenon,
In extraction tower, so-called Water-In-Oil refers to that the working solution of light phase is wrapped in heavy phase water and forms bubble, leads to working solution and water
It is not readily separated, a large amount of water is carried over extraction tower, has not only aggravated the workload of aftertreatment technology, and aggravated to disappear to pure water
Consumption.Therefore it needs to handle raffinate, to recycle pure water and reduce the workload of post-processing.It commonly uses as shown in Figure 1
Equipment raffinate is handled, i.e., the raffinate that extraction tower 01 is discharged isolates the portion that may be carried secretly through extraction raffinate separator 02
Divide water and then is post-processed by entering after-treatment device 05 after working solution measuring tank 03；In this process, it need to manually control
Pure water of the system ground through isolating discharges into pure water accumulator tank 04, and not only number of devices is more, and manual operation is complicated.
Due to the process recycled in working solution, moisture therein need to be removed using after-treatment device 05, to prevent existing
Explosion danger.Currently, the method removed water in industrial production to working solution has vacuum dehydration method, alkali evaporation and publication number
Water-oil separating method disclosed in patent document for CN104370331A.
For alkali evaporation, as shown in Fig. 2, its after-treatment device 05 includes washing tower (for removing CO2) 06, alkali separator 07, caustic settler
08, the top of carclazyte bed 091, alkali collection slot 092 and alkali evaporator 093, washing tower (for removing CO2) 06 is connected to by pipeline with alkali separator 07, alkali
Separator 07 is connected to by pipeline with caustic settler 08, and caustic settler 08 is connected to by pipeline with carclazyte bed 091.In the course of work
In, the working solution of the top of (1) extraction tower 01 outflow is after extraction raffinate separator 02 separates the part water that may be carried secretly, from 06 bottom of washing tower (for removing CO2)
The material mouth in portion enters washing tower (for removing CO2) 06；(2) it is provided with dense solution of potassium carbonate in washing tower (for removing CO2) 06, for removing remaining water in working solution
Divide, neutralize acids and decompose remaining hydrogen peroxide；(3) working solution flowed out at the top of washing tower (for removing CO2) 06 followed by alkali separator 07 with
Caustic settler 08, after isolating the solution of potassium carbonate that may be carried secretly, working solution enters back into carclazyte bed 091 and is handled, and isolates
Solution of potassium carbonate be collected in alkali collection slot 092.Diluted solution of potassium carbonate and alkali collection is collected in washing tower (for removing CO2) 06
Solution of potassium carbonate in slot 092 is recycled by reentering in washing tower (for removing CO2) 01 after 093 inspissation of alkali evaporator.
But for remaining hydrogen peroxide enters washing tower (for removing CO2) 06 with working solution in working solution after extracting after, in washing tower (for removing CO2) 06
Violent decomposition reaction can occur, release bulk gas and heat, if gas has little time to discharge, will cause washing tower (for removing CO2) and 06 surpass
Pressure, and gas also occurs that in washing tower (for removing CO2) 06 and is bubbled and generates " Water-In-Oil " phenomenon, so-called " Water-In-Oil " refers to the work of light phase
Liquid is wrapped in potassium carbonate and forms bubble, causes working solution and solution of potassium carbonate to be not readily separated, a large amount of solution of potassium carbonate is carried over
Washing tower (for removing CO2) 06 not only results in the reduction of solution of potassium carbonate concentration in washing tower (for removing CO2) 06 and reduces the service life of dense potassium carbonate, increases
The consumption of potassium carbonate, and aggravated alkali separator 07, caustic settler 08, alkali evaporator 093 and manually-operated load.
