Description
Technical field
A kind of gravity flow U-shaped liquid seal structure for the sampling of mixed triolein negative pressure operating condition medium of the utility model, belongs to mixed triolein
Processing technique field.
Background technique
Tar distillation majority is single-furnace double-tower negative pressure continuous distillation process at present, and the mixed triolein gas phase of fraction overhead is through being subcooled
From mixed triolein storage tank is flowed into after solidifying, because system takes out negative pressure from mixed triolein vapor delivery line, therefore mixed triolein must underthrust into storage tank
Certain height liquid seal guarantee will not vacuum breaker.But in mixed triolein sampling operation, opening sample cock, which is equivalent to, to be abolished very
Sky, not only due to the reason of negative pressure can not take sample, it is also possible to cause entire negative pressure system pressure oscillation, shadow is caused to production
It rings.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides one kind and takes for mixed triolein negative pressure operating condition medium
The gravity flow U-shaped liquid seal structure of sample, breaching conventional negative hydraulic fluid tube sealing road must be inserted into the limitation of reservoir bottom, both meet fluid-tight
It is required that while avoiding the danger got angry inside storage tank.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: one kind is used for mixed triolein negative pressure work
, there is height between the drainer and oil storage tank in the gravity flow U-shaped liquid seal structure of condition medium sampling, including drainer and oil storage tank
Difference, and drainer is located at the top of oil storage tank, upside one end of the drainer is provided with gas-phase feed pipe, the drainer
The upside other end is provided with negative pressure drainage tube, is connected between the downside and oil storage tank upside of the drainer by U-tube, described
One end of U-tube is connected to drainer, and the other end of the U-tube is connected to oil storage tank, and the U-tube connect one with drainer
The height of side matches with the negative pressure in negative pressure drainage tube, and the pressure that the oil liquid in the height generates is greater than in negative pressure drainage tube
Negative pressure, the lower end of the U-tube is provided with sampling pipe.
It is flushed on the downside of the downside of the U-tube and oil storage tank.
The side of the drainer is provided with the circulation line for recirculated cooling water.
Valve is provided on the gas-phase feed pipe, negative pressure drainage tube, U-tube both ends and sampling pipe.
The utility model has the beneficial effect that the utility model by mixed triolein cooler outlet compared with prior art
Pipeline is transformed, and pipeline is walked into downward big U-bend after calculating required height liquid seal, under curved length meet and be more than
Required vacuum height liquid seal does not have to thus be intubated under making in storage tank again, facilitates construction.Sample tap position is set simultaneously
Setting the moment in the bottom of U-bend, U-bend is flowing full state, and opening valve can sample, and reduces the labor intensity of employee,
Improve working efficiency.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 being drainer, 2 be oil storage tank, 3 be gas-phase feed pipe, 4 be negative pressure drainage tube, 5 be U-tube, 6 be sampling
Pipe, 7 be circulation line, 8 be valve.
Specific embodiment
As shown in Figure 1, a kind of gravity flow U-shaped liquid seal structure for the sampling of mixed triolein negative pressure operating condition medium of the utility model,
Including drainer 1 and oil storage tank 2, there are differences in height between the drainer 1 and oil storage tank 2, and drainer 1 is located at oil storage tank 2
Top, upside one end of the drainer 1 is provided with gas-phase feed pipe 3, and the upside other end of the drainer 1 is provided with negative
Press drainage tube 4, the downside of the drainer 1 and oil storage tank are connected between 2 upside by U-tube 5, one end of the U-tube 5 with
Drainer 1 is connected to, and the other end of the U-tube 5 is connected to oil storage tank 2, and the U-tube 5 connect the height of side with drainer 1
Match with the negative pressure in negative pressure drainage tube 4, and the pressure that the oil liquid in the height generates is greater than bearing in negative pressure drainage tube 4
Pressure, the lower end of the U-tube 5 is provided with sampling pipe 6.
The downside of the U-tube 5 is flushed with the downside of oil storage tank 2.
The side of the drainer 1 is provided with the circulation line 7 for recirculated cooling water.
Valve 8 is provided on the gas-phase feed pipe 3, negative pressure drainage tube 4,5 both ends of U-tube and sampling pipe 6.
The course of work of the utility model: mixed triolein cooler outlet pipeline is transformed, required fluid-tight is calculated
Pipeline is walked into downward big U-bend after height, under curved length meet and be more than required vacuum height liquid seal, thus do not have to again
It is intubated under being made in storage tank, facilitates construction.Sample tap position is arranged in the bottom of U-bend simultaneously, in U-bend the moment be
Flowing full state, opening valve can sample, and reduce the labor intensity of employee, improve working efficiency.
The utility model is explained in detail above in conjunction with embodiment, but the utility model is not limited to above-mentioned implementation
Example, within the knowledge of a person skilled in the art, can also be in the premise for not departing from the utility model aims
