Abstract
The utility model relates to a liquid-storage pot of isolating burst by nitrogen, comprising a liquid-storage pot, a feed pipeline and a discharge pipeline. The utility model is characterized in that: the sealed top of the liquid-storage pot is provided with a breather pipe which is connected with a blower, and the blower is connected with a nitrogen storage groove; the liquid-storage pot is provided with an air pressure probe, and the air pressure probe signal is connected with a controller which is connected with the blower; the liquid-storage pot is provided with a pressure-limited safety valve. The liquid-storage pot can safely isolate the liquid level of the liquid-storage pot from contacting with the air and prevent the happening of exploding accidents.
Description
Technical field
The utility model relates to a kind of fluid reservoir, particularly a kind of fluid reservoir that utilizes the nitrogen flame proof.
Background technology
In chemical industry, be extensive use of various storage tanks at present, because the chemical of being stored in storage tank has plenty of explosive spontaneously inflammable dangerous material, when running into air, very easily cause the danger that fires, for safety, more existing storage tanks seal with various obturators, but because some storage tanks work online, wherein the article of being stored change along with production process, constantly enter as the liquid of being stored, then the air on the tank level constantly pressurizes and can produce pressure to jar, also influenced the input of normal liquid simultaneously, and the liquid of storage is discharged from, then, influence the normal discharge of liquid in the storage tank by the negative pressure on the meeting generation liquid level.
Summary of the invention
The purpose of this utility model is to solve in the prior art to utilize closing appliance to isolate existing the problems referred to above of dangerous material in the storage tank, and a kind of flame proof fluid reservoir that utilizes nitrogen effectively to isolate dangerous material is provided.A kind of fluid reservoir that utilizes the nitrogen flame proof of the utility model design comprises fluid reservoir, feeding line, discharging pipeline, and it is characterized in that: the closure tip at fluid reservoir is connected to breather pipe, the breather pipe machine of giving a dinner for a visitor from afar, and blower fan connects the nitrogen storage air drain.Air pressure probe is arranged on fluid reservoir, and the air pressure probe signal connects controller, the controller machine of giving a dinner for a visitor from afar.Pressure-limiting safety valve is arranged on fluid reservoir.The utility model has the advantages that to completely cut off contacting of fluid reservoir liquid level and air safely, prevent the generation of blast accident.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise fluid reservoir 1, feeding line 2, discharging pipeline 3 among the figure, it is characterized in that: the closure tip at fluid reservoir 1 is connected to breather pipe 4, breather pipe 4 machine 5 of giving a dinner for a visitor from afar, and blower fan 5 connects nitrogen storage air drain 6.At fluid reservoir 1 top air pressure probe 7 is arranged, air pressure probe 7 signals connect controller 8, controller 8 machine 5 of giving a dinner for a visitor from afar.Pressure-limiting safety valve 9 is arranged on fluid reservoir 1.During use, when by feeding line 2 in the fluid reservoirs 1 during perfusion fluid, its liquid level rises, the space pressure on fluid reservoir 1 top strengthens, at this moment, after the air pressure probe 7 at fluid reservoir 1 top detects, open blower fan 5, blower fan 5 is reduced to normal value with the nitrogen suction nitrogen storage air drain 6 in fluid reservoir 1 upper space until the air pressure at fluid reservoir 1 top.When the liquid in the fluid reservoir 1 is discharged by discharging pipeline 3, form a negative pressure at fluid reservoir 1 top, after the air pressure probe 7 at fluid reservoir 1 top detects, open blower fan 5, blower fan 5 is with in nitrogen suction fluid reservoir 1 upper space in the nitrogen storage air drain 6, and the air pressure until fluid reservoir 1 top rises to normal value.So just can keep the liquid level in the fluid reservoir 1 isolated by nitrogen and air, prevent the generation of blast accident, pressure-limiting safety valve 9 on the fluid reservoir 1 is in order to guarantee when the device fails, provides the passage of a pressure release or air inlet to fluid reservoir 1, prevents that fluid reservoir 1 from explosion taking place or subside.
Claims (3)
1, a kind of fluid reservoir that utilizes the nitrogen flame proof comprises fluid reservoir, feeding line, discharging pipeline, and it is characterized in that: the closure tip at fluid reservoir is connected to breather pipe, the breather pipe machine of giving a dinner for a visitor from afar, and blower fan connects the nitrogen storage air drain.
2, by the described a kind of fluid reservoir that utilizes the nitrogen flame proof of claim 1, it is characterized in that: air pressure probe is arranged on fluid reservoir, and the air pressure probe signal connects controller, the controller machine of giving a dinner for a visitor from afar.
