Abstract
The utility model discloses a liquid has nitrogen to seal storage tank that requires, its characterized in that: including liquid nitrogen container, liquid nitrogen container establishes ties through the pipeline in proper order has the liquid nitrogen vaporizer, relief pressure valve, finished product storage tank, spark arrester, individual calling valve, blow -down pipe. The beneficial effects of the utility model are that: the investment cost is reduced, the volume of examining maintenance work is few, and fail safe nature is high, has reduced exhaust emission, has realized that safety ring protects and cleaner production's purpose, has improved economic benefits.
Description
Technical field
The utility model belongs to field of chemical equipment, and particularly relating to a kind of liquid has nitrogen to seal the storage tank required.
Background technology
The petrochemical enterprise of China is more, and Large-scale enterprises raw MAT'L and product storage tank more.Due to the development of existing industrial economy and the contradiction of social environment, the requirement of people to environment is more and more higher, and country is also more and more stricter to relevant environmental protection.Therefore, how to reduce the waste gas that storage tank produces in the process of input and output material, prevent and alleviate environmental concerns and the impact on the person.In such a case, nitrogen seal device arises at the historic moment.Existing nitrogen seal device by storage tank, enter nitrogen valve, let out nitrogen valve and breathing valve forms, but concerning the storage tank of multiple same material, carry out according to this nitrogen seal device, investment is comparatively large, and checking maintenance work capacity is large from now on.Therefore, adopt suitable technological improvement nitrogen seal device, not only reduce investment, and be conducive to checking maintenance work capacity from now on, especially each reservoir gas balance can also save the use amount of nitrogen, reduces productive costs, thus improves the economic benefit of enterprise.
At present, methylphenylamine nitrogen seal device, all adopts into nitrogen valve, the pattern of letting out nitrogen valve and breathing valve.The shortcomings such as the method input cost is high, and checking maintenance work capacity is large.
Therefore need a kind of input cost few, checking maintenance facilitates and the methylphenylamine storage tank nitrogen seal device of safety from now on.
Summary of the invention
Goal of the invention of the present utility model is: for above-mentioned Problems existing, and provide a kind of input cost little, checking maintenance work capacity is few, and the higher liquid of safety has nitrogen to seal the storage tank required.
The technical solution adopted in the utility model is such: a kind of liquid has nitrogen to seal the storage tank required, it is characterized in that: comprise liquid nitrogen container, described liquid nitrogen container is in series with liquid nitrogen vaporizer, reducing valve, finished product storage tank, flame trap, single breathing valve, blow-down pipe successively by pipeline.
Further, in case superpressure in negative pressure and tank, this device also comprises safety device, and described safety device comprises water sealed tank and breathing valve, described water sealed tank is other to be connected between described liquid nitrogen vaporizer and finished product storage tank, and described breathing valve is other to be connected between finished product storage tank and blow-down pipe.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: reduce cost of investment, checking maintenance work capacity is few, and safe reliability is high, decreases exhaust emission, achieve the object of safety, environmental protection and cleaner production, improve economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 is liquid nitrogen container, and 2 is liquid nitrogen vaporizer, and 3 is reducing valve, and 4 is finished product storage tank, and 5 is flame trap, and 6 is single breathing valve, and 7 is blow-down pipe, and 8 is water sealed tank, and 9 is breathing valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of methylphenylamine storage tank nitrogen seal device, by liquid nitrogen container 1, is in series with liquid nitrogen vaporizer 2, reducing valve 3, water sealed tank 8, finished product storage tank 4, flame trap 5, breathing valve 9, single breathing valve 6, blow-down pipe 7 successively by pipeline.
From the nitrogen of system after two-stage decompression to 500 handkerchief, enter methylphenylamine storage tank.When in storage tank during input and output material, each storage tank self-balancing pressure.After tank inner pressure is more than 500 handkerchiefs, automatically cut off nitrogen air inlet reducing valve, tank internal pressure is more than after 980 handkerchiefs, and single breathing valve is opened, and is vented from blow-down pipe to treatment and finishing section.As lower than 500 handkerchiefs, then nitrogen valve opens automatic feeding, decreases exhaust emission.On pipeline, water sealed tank and breathing valve are as safety device, in case superpressure in negative pressure and tank.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
