Abstract
It the utility model is related to organic matter recovery technology field, a kind of more particularly to water knockout drum of high efficiente callback toluene, including babinet, the wall box is provided with inlet, the babinet side wall opposite with the inlet is provided with organic solvent outlet, the bottom of box is provided with water outlet, and the bottom that the casing top is provided with baffle A, the baffle A is exported less than the organic solvent.The utility model in babinet by adding liquid flow baffles, prevent that direct impact liquid level, makes the water containing part in the toluene of recycling to aqueous liquid after the inlet of water knockout drum enters, improve toluene recovery efficiency and recycle the purity of toluene, be conducive to the synthetic reaction of p-methyl benzenesulfonic acid.
Description
Technical field
Organic matter recovery technology field is the utility model is related to, more particularly to a kind of water knockout drum of high efficiente callback toluene.
Background technology
The synthesis of industrial p-methyl benzenesulfonic acid is typically to be carried out in tower reactor, and reaction temperature is 110 DEG C ~ 135 DEG C,
The water and toluene vapor of generation flow out at the top of tower reactor.Toluene is a kind of dangerous organic chemicals, Long Term Contact first
Neurasthenic syndrome can occur for benzene, have irritation to skin, mucous membrane, Central nervous system plays the role of anesthesia, toluene
Steam can form explosive mixture with air, if toluene is directly launched in environment, not only to air, water environment and water source
It can cause seriously to pollute, influence human health, and improve production cost.
Toluene is atomic to be dissolved in water, and the density ratio water of toluene is small, therefore this characteristic of toluene can be utilized to utilize water knockout drum
Toluene recovery is utilized, but common water knockout drum is difficult that toluene and water is completely separable, when aqueous liquid is from toluene recovery
After the inlet of device enters, direct impact liquid level, so that the water containing part in the toluene of recycling, water are followed with toluene
After ring enters tower reactor, the synthesis of p-methyl benzenesulfonic acid can be influenced.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, and provide a kind of high efficiente callback toluene divides water
Device, which solves after aqueous liquid enters from the inlet of toluene recovery device, direct impact liquid level, so that recycling
In toluene the problem of water containing part.
Technical solution is used by the utility model solves its technical problem：A kind of water knockout drum of high efficiente callback toluene,
Including babinet, the wall box is provided with inlet, and the babinet side wall opposite with the inlet is provided with organic molten
Agent exports, and the bottom of box is provided with water outlet, and the bottom that the casing top is provided with baffle A, the baffle A is less than institute
State organic solvent outlet.
The bottom of box is provided with baffle B.
There is gap between the baffle B bottoms and the bottom of box.
The baffle A is fixedly connected on the casing top.
The water outlet Method for Installation valve.
The wall box is provided with observation window.
The beneficial effects of the utility model are：The utility model is prevented by adding liquid flow baffles in babinet
For aqueous liquid after the inlet of water knockout drum enters, direct impact liquid level, makes the water containing part in the toluene of recycling, improves
Toluene recovery efficiency；The toluene of recycling is not aqueous, and purity is high, is conducive to the synthesis of p-methyl benzenesulfonic acid.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Description of reference numerals：
1 --- babinet, 2 --- inlet, 3 --- organic solvent exports, and 4 --- water outlet, 5 --- baffle A, 6 ---
Baffle B, 7 --- valve, 8 --- observation window.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is not this practicality
New practical range limited to this.
As shown in Figure 1, a kind of water knockout drum of high efficiente callback toluene of the present embodiment, including babinet 1,1 side wall of babinet
Inlet 2 is provided with, the babinet 1 side wall opposite with the inlet 2 is provided with organic solvent outlet 3,1 bottom of babinet
Portion is provided with water outlet 4, and the bottom that the top of babinet 1 is provided with baffle A5, the baffle A5 goes out less than the organic solvent
Mouth 3, the baffle A5 are fixedly connected on the top of babinet 1.
The synthesis of p-methyl benzenesulfonic acid is using the concentrated sulfuric acid and toluene as raw material, and temperature is 110 DEG C ~ 135 DEG C, in tower reactor
Middle reaction, reacts the water of generation with vapor form and unnecessary toluene vapor, enters from the steam (vapor) outlet of tower reactor cold
It is solidifying to manage, separated in condensed liquid, aqueous entrance water knockout drum, recycle toluene.By setting institute inside the babinet 1
Baffle A5 is stated, reduces aqueous liquid from water knockout drum inlet into fashionable, the impact to liquid level, prevents from containing in the toluene of recycling
Water, influences toluene recovery efficiency.
1 bottom of babinet is provided with baffle B6.The baffle B6 is identical with the effect of the baffle A5, is all to reduce to contain
The liquid of water prevents from containing water in the toluene of recycling, influences toluene recovery from water knockout drum inlet into fashionable, the impact to liquid level
Efficiency.
There are gap in the baffle B6 bottoms and the babinet between 1 bottom, are conducive to the flowing of liquid in babinet 1.
The 4 Method for Installation valve 7 of water outlet, 1 side wall of babinet are provided with observation window 8.It can be observed by observation window 8
The capacity of water in babinet, after water reaches certain capacity, opens the outlet valve 7 of 1 bottom of babinet, water is discharged, discharge
Water is passed through in condenser pipe as cooling medium.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this
The spirit and scope of utility model technical solution.
