Background technique:
Hydrogen peroxide production process process are as follows: (main component is trimethylbenzene, is separately had by diethyl anthraquinone, heavy aromatics
A small amount of dimethylbenzene, toluene), the composition working solution such as trioctyl phosphate, the anthraquinone in working solution is in the hydrogenation for being filled with palladium catalyst
It is reacted in tower with hydrogen, generates hydrogen anthraquinone, hydrogen anthraquinone is in oxidizing tower and oxygen reaction generates anthraquinone and hydrogen peroxide, then is extracting
The hydrogen peroxide in working solution is extracted by pure water in tower.Enter after raffinate working solution removing part water containing a certain amount of water
Carclazyte bed after regenerating degradation product therein, reenters hydrogenation tower circular response.
The dewatering work process of raffinate working solution is: isolating part free water by extraction raffinate separator first, passes through
Metering pump infuses alkali, is uniformly mixed in alkali mixer to reach the requirement of the basicity of hydrogenation process, subsequently into drain sump, removes work
Make the molecular water and free water in liquid, to reach the requirement for entering carclazyte bed regeneration degradation product.
But existing hydrogen peroxide drain sump mainly uses tubular heat exchanger device, low-pressure steam is flowed from tubulation, tubulation
To raffinate thermal dehydration in a raffinate liquid bath.This drain sump is substantially a kind of vaporising device, utilizes heating steam
Moisture in raffinate is vaporized and is removed.What this device had maximum is a large amount of heating steam of needs consumption, and this
Kind is lower using the heat transfer efficiency that heating tube is conducted heat, and also needs to increase filtering, condensation for the utilization of secondary steam
Equipment increases the cost for raffinate fluid dewatering, and during heating evaporation, and the carriers such as anthraquinone in raffinate can be sent out
The phenomenon that blocking pipeline is precipitated in raw crystallization, influences to produce.
Utility model content:
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of hydrogen peroxide vacuum extractors.
The utility model is implemented by following technical solution: a kind of hydrogen peroxide vacuum extractor, including cylinder, in the cylinder
End sealing be equipped with upper cover, the cylinder bottom end seal be equipped with lower head,
It is fixed with tube sheet in the upper level of the cylinder lumen, the cylinder lumen in the tube sheet lower part is vertical
Equipped with several variable diameter tubulations, the tube sheet is run through in the upper end of the variable diameter tubulation, and is fixedly connected with the tube sheet；
It is equipped with raffinate import on the cylinder lateral wall on the tube sheet top, vapor is equipped on the upper cover
Outlet is equipped with raffinate outlet on the lower head, and valve is equipped on the raffinate outlet.
Further, funnel shaped liquid collecting bucket, the bottom opening of the liquid collecting bucket are equipped in the lower part of the cylinder lumen.
Further, the lower end of the variable diameter tubulation is abutted with the liquid collecting bucket, convenient for raffinate in variable diameter tubulation along
Liquid collecting bucket flows downward, and raffinate is avoided to be gathered in variable diameter tubulation lower end, and the carriers such as anthraquinone in raffinate occur crystallization and are precipitated
Block variable diameter tubulation.
Further, the upper end of the variable diameter tubulation is concordant with the upper end of the tube sheet.
Further, the cylinder lumen on raffinate import top is fixed with sieve, on the one hand avoids extracting
The foam that extraction raffinate generates under the action of negative pressure is taken away with steam, plays the role of foam removal；On the other hand it is convenient for its carried secretly in steam
He is aggregated liquid on sieve, avoids being taken away by steam.
The advantages of the utility model:
1, the inside of the utility model dehydrator due to be equipped with tube sheet and variable diameter tubulation, raffinate can be made to be uniformly dispersed,
Keep the water in raffinate more easily separated, improves dehydration efficiency.
2, the utility model is provided with liquid collecting bucket in the bottom of variable diameter tubulation, convenient for the collection of variable diameter tubulation lower end liquid,
Variable diameter tubulation bottom end is avoided to be aggregated drop, the carriers such as anthraquinone in liquid occur crystallization and are precipitated and block tubulation.
3, the utility model is equipped with sieve on the top of cylinder, on the one hand for preventing raffinate from generating under the action of negative pressure
Foam taken away with steam, play the role of foam removal；On the other hand other liquid convenient for carrying secretly in steam are aggregated on sieve, are kept away
Exempt to be taken away by steam, improves dehydration quality.
Detailed description of the invention:
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of hydrogen peroxide vacuum extractor of the present embodiment.
In figure: cylinder 1, upper cover 2, lower head 3, tube sheet 4, variable diameter tubulation 5, liquid collecting bucket 6, raffinate import 7, vapor
Outlet 8, raffinate outlet 9, valve 10, sieve 11.
Specific embodiment:
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
