Abstract
The utility model discloses a novel benzene separating device by negative-pressure distillation. The novel benzene separating device comprises an oval slot, wherein a separating slot is arranged at the lower side of the oval slot; a glass tube liquid indicator is arranged on the outer side of the separating slot; a through liquid flow gap is arranged between the oval slot and the separating slot; and a static separating layer is additionally arranged. According to the novel benzene separating device disclosed by the utility model, the static separating slot is additionally arranged on the lower side of the original oval slot, so the original two-step benzene and water separating process is replaced by one slot, the separating effect is achieved, and device investment and operation steps are reduced. The separating slot can be adaptive to a negative-pressure distillation process, and benzene and water can be well separated by virtue of the structure and strength of the slot structure under the negative-pressure status, so that negative-pressure control is effectively ensured, and guarantee is provided for the continuous operation of the negative-pressure distillation system.
Description
Technical field
The utility model relates to a kind of benzene water separation device in the coal chemical enterprise benzene class distil process, and specifically a kind of novel negative pressure steams the benzene separator.
Background technology
The water at atmospheric pressure steam distillation is used in existing most domestic coal chemical enterprise benzene class distillation, and the benzene class that wherein distills need to be separated just through oil water separator and two steps of control separator with water can reach preferably separating effect.And need independent reflux column to realize benzene class condensing reflux, equal could realize separating of benzene class and water with three equipment.The separation principle of traditional oil water separator is to adopt the thin layer shallow pool theory, some parts such as water-distributing device and corrugated plating that catchment are set in an airtight container exactly, make the little fluid come-up of density, heavy moisture sinks, the oil drain out of fluid after the separation from the top of groove overflows and reclaims, and the moisture after the separation is discharged and reclaimed from trench bottom.And by surveying oil-water interfaces to cooperate electromagnetic switch be to realize the automatic control of oil drain out and discharge outlet, finally realize the purpose of water-oil separating.
After the negative pressure benzene braising system was finished in the Some Enterprises exploitation, the separator of above benzene class and water was inapplicable, need to transform and could satisfy instructions for use.
The utility model content
For above-mentioned situation, the utility model aim to provide a kind of can effective separation benzene class and water, cost is low again, also can realize again the separator of negative-pressure vacuum device stable operation.
The technical scheme in the invention for solving the technical problem is: a kind of novel negative pressure steams the benzene separator, comprise oval cell body, in described oval cell body, be provided with water-locator and corrugated plating, described oval cell body is provided with inlet, it is characterized in that, positive downside at described oval cell body is provided with a separating tank, and at glass-tube liquid level meter of arranged outside and the pressure reduction liquid level gauge of separating tank, and between described oval cell body and separating tank, be provided with the liquid flow gap of perforation; Benzene class and water enter again standing separation of bottom separating tank after the initial gross separation in the oval cell body in top, cooperate outer glass pipe liquid level gauge and pressure reduction liquid level gauge, observe and measure the two media interface, control product quality well.
The beneficial effects of the utility model are:
(I) is horizontal by increasing a separating tank that leaves standstill at original oval cell body downside, and intensity is high, replaced original benzene class and two step of water separating technology with a cell body, and reached separating effect, reduced equipment investment and operating procedure;
(II) this separating tank can adapt to vacuum distillation technique, under negative pressure state, this separating tank trough body structure and intensity still can realize preferably benzene class and moisture from, make negative pressure control make effective assurance, also for the vacuum distillation system continuously operation guarantee is provided;
The utility model Research Thinking is novel, and technological investment is few, does not have complicated especially equipment, is easy to observe, and is simple to operate, has good economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1 oval cell body, 2 separating tanks, 3 glass-tube liquid level meters.
The specific embodiment
As shown in Figure 1,
A kind of novel negative pressure steams the benzene separator, comprise oval cell body 1, in oval cell body 1, be provided with water-locator and corrugated plating, water-locator is used for oil-water mixture is distributed, be conducive to the separation of benzene class, oval cell body is provided with inlet, and inlet is installed water-locator, and corrugated plating can effectively separate the small benzene oil particles in the water.Separating tank 2 of positive downside welding at oval cell body 1, whole tank body for the sealing shape, separating tank 2 is long, and at glass-tube liquid level meter 3 of arranged outside and the pressure reduction liquid level gauge of separating tank 2, can observe liquid level situation in the separating tank by this glass-tube liquid level meter 3, and be provided with the liquid flow gap of perforation between oval cell body and separating tank, the liquid in two cell bodies can be realized intercommunication; Benzene class and water enter again standing separation of bottom separating tank after the initial gross separation in the oval cell body in top, cooperate outer glass pipe liquid level gauge and pressure reduction liquid level gauge, observe the two media interface, control product quality well.
The benzene class that the utility model energy single device effective separation benzene steaming tower top steams and the backflow of water can make the negative-pressure vacuum device effectively be guaranteed, are the continuously bases of operation of negative pressure benzene braising system, have reduced simultaneously equipment investment.The utility model Research Thinking is novel, and technological investment is few, does not have complicated especially equipment, is easy to observe, and is simple to operate, has good economic benefit.
