Description
Technical field
The utility model belongs to chemical material storage apparatus field, specifically a kind of flashback tank.
Background technique
In numerous chemical materials, there is considerable part to need air-isolation when stored, it will usually set such material
In the bulk storage tanks of sealing, tank internal upper part drains air, and instead nitrogen or other inactive gases are saved.Due to
Gas volume is larger by temperature change, therefore exhaust pipe has been also conducted on holding vessel, so as at any time can be by extra gas
Discharge.But the presence of exhaust pipe may also lead to other gases and inversely be mixed into holding vessel, therefore will usually be vented pipe end
It is connected on flashback tank, is acted on by water seal, not only can be convenient positive exhaust, but also can be to avoid reverse air inlet.Chinese patent text
It offers CN204729684U and discloses " a kind of water sealed tank " on October 28th, 2015, be equipped with horizontal tank body (1), tank body is equipped with fire
Torch discharges gas inlet duct (2) and flare discharge gas outlet conduit (3).The outside of flare discharge gas inlet duct is equipped with perforated panel
(5), perforated panel is horizontally placed in tank body in the extreme lower position of sealing water level (4).Axial direction of the lower part of tank body along tank body (1)
Two pieces of anti-wave baffles (6), axial direction of the anti-wave baffle perpendicular to tank body are at least set.The top of anti-wave baffle is located at sealing water level
Extreme higher position on, bottom be located at sealing water level extreme lower position under.The bottom of anti-wave baffle be disposed below
Sealing water communication port is formed between the inner wall of tank body.In the technical scheme, perforated panel is located at the water around admission line lower end
Prosposition is set, and the atmosphere stream of concentration can be separated into minute bubbles, is had the effect of to weakening liquid level wave certain.But current water
In joint sealing, control liquid level will lead to liquid level fluctuation, make ball-cock assembly pair using ball-cock assembly, acutely gushing out for bubble
The control precision of liquid level reduces；Simultaneously because liquid fluctuating is frequent, ball-cock assembly long-term action is easily damaged.
Summary of the invention
Based on problem above, the utility model provides a kind of flashback tank, can stabilize liquid level big ups and downs caused by bubble,
The adverse effect to ball-cock assembly is eliminated, systems stabilisation pressure reduces the consumption of sealing fluid and inert gas, extends cabinet ball-cock assembly
Service life.
In order to realize goal of the invention, the utility model adopts the following technical solution：A kind of flashback tank, including cabinet, cabinet

Be divided into independent two regions relative to each other with exhaust inlet pipe region, the gas part of two overlying regions strictly every
From, and lower section only has sealing fluid connection.Such design, so that the air-flow from exhaust inlet pipe is in the case where overflowing exhaust inlet pipe
After end pipe mouth, can only emerge liquid level in the region of place side, caused by liquid fluctuating also stopped by vertical baffle, can not transmit
To the other side, that is, ball-cock assembly side, to drastically reduce the influence to ball-cock assembly；And communicated below liquid level, liquid level is high
Low variation still can normally be transferred to ball-cock assembly, and driving ball-cock assembly controls the normal opening and closing of inlet tube.On porous plate
The optional circular hole in hole, elliptical aperture, slotted hole either shape changeable hole, arrangement are generally advisable with matrix arrangement.The inclination angle of porous plate
The general optional and horizontal plane of degree is at any number within 60 °.
Preferably, the lower end of vertical baffle is not higher than the depth where the hole that position is minimum on porous plate.This programme limit
The depth for having determined vertical baffle makes to pour in subsurface atmosphere and flows to end and possible overflows from porous plate side.Only work as throughput
When very big very rapid, the lower end that part bubble climbs over vertical baffle is just had, is emerged liquid level from ball-cock assembly side.It answers at this time
When belonging to emergency, the demand of equipment safety should be placed on the requirement of ball-cock assembly service life.
Preferably, being additionally provided with horizontal baffle；Horizontal baffle is horizontally disposed, with the lower end of exhaust inlet pipe, porous plate
Upper end is connected with vertical baffle, and is extended to along the direction of horizontal baffle and connect with wall box.Horizontal baffle further seals
The gap between vertical baffle, exhaust inlet pipe lower end and porous plate has been closed, has passed through air-flows all under normal circumstances excessively
Orifice plate and obtain shunt weaken.
Preferably, be additionally provided with middle partition, middle partition is by the two parts up and down that are divided into of box sealing, porous plate and vertical
The upper surface gap Jun You of the lower end of baffle and middle partition；Sealing fluid is located at cabinet top；Overflow pipe being fixed on up and down
On middle partition, overflow pipe upper end opening is higher than the calibrated altitude of liquid level.This programme is also provided with another sealing below cabinet
Space, only communicated by overflow pipe between the above space of the liquid level of same top, overflow pipe upper end be higher than liquid level it is a little, with control
Liquid fluctuating degree processed, if degree of fluctuation is larger, the part higher than overflow pipe upper end opening will flow to lower section through overflow pipe,
This just further suppresses the fluctuating of top liquid level.Overflow pipe upper end is higher than the height of liquid level, as level allowance fluctuation most
Big value, the value can also sets itself as needed, such as 2mm, i.e. liquid fluctuating is more than the part of 2mm by overflow pipe row
Out.
Preferably, overflow pipe is located at the ball-cock assembly side of vertical baffle.Overflow pipe is arranged in the floating ball of vertical baffle
Valve side can achieve optimal inhibition ripple effect.
Preferably, the side wall and/or bottom plate of lower box are equipped with inlet tube and drain pipe able to turn on or off, lower box
It is perfused with appropriate sealing fluid, the lower ending opening of overflow pipe is immersed under liquid level.Such design can further avoid gas from
Overflow pipe lower end enters cabinet upper space.
In conclusion the utility model has the beneficial effects that：Liquid level big ups and downs caused by bubble, elimination pair can be stabilized
The adverse effect of ball-cock assembly, systems stabilisation pressure reduce the consumption of sealing fluid and inert gas, extend the use of cabinet ball-cock assembly
Service life.
