Description
Technical field
A kind of space division system water-cooling tower automatic overflow device is the utility model is related to, belongs to air separation unit technique field.
Background technology
In space division chilldown system, the main function of dirty nitrogen water-cooling tower level overflowing device is aqueous position in adjusting tower,
Avoid superelevation.At present, most water-cooling tower overflow mechanisms overflow as shown in figure 1, carrying out draining by the drainpipe in tower wall
Stream, when liquid level is higher by setting value in tower, the stop valve that operating personnel's on-site manual is opened on drainpipe carries out draining；And
In traditional overflow mechanism, do not account for anti-siphon and set, stop valve is such as intervened manually not in time once opening, cooling tower
For water under siphonage, meeting continued emissions to liquid level and water sucking mouth are horizontal, cause liquid level too low, so as to cause water pump parking and sky
The generation of subsystem interlock shutdown phenomenon；And because human factor is heavier, once field instrument display mistake or operating personnel dredge
Suddenly, causing water-cooling tower liquid level too high, dirty nitrogen entrance in water-cooling tower can be caused to block, dirty nitrogen can not be discharged normally, so that
Nitrogen gas purity is destroyed in moment, is in turn resulted in subsequent user and is contaminated, and causes to have a strong impact on.Meanwhile the row of most water-cooling towers
Water needs individually laying blow-off line, causes cross pollution to prevent being shared with public blow-off line, and then influence changing for water-cooling tower
Thermal effect.
Utility model content
Technical problem to be solved in the utility model provides a kind of space division system water-cooling tower automatic overflow device, without people
Work manipulation regulation, it is automatic to ensure liquid level in the safe range of setting, and shared public blow-off line is realized, avoiding handing over
While fork pollution, ensure water-cooling tower heat transfer effect.
Solve above-mentioned technical problem technical scheme be：
A kind of space division system water-cooling tower automatic overflow device, including drainpipe, drainpipe water sucking mouth are located in water-cooling tower, row
The mouth of a river is located at outside water-cooling tower, and its improvements is：The discharge outlet of drainpipe is connected with anti-siphonage pipe, and anti-siphonage pipe upper port is high
In drainpipe discharge outlet position；The lower port of anti-siphonage pipe is connected with U-shaped liquid sealing pipe, and the other end connection of U-shaped liquid sealing pipe is public
Blow-off line.
A kind of above-mentioned space division system water-cooling tower automatic overflow device, the anti-siphonage pipe are the straight tube of upper end bending；Institute
State and observation tube is connected with the middle part of anti-siphonage pipe, angle is acute angle and observation tube between axis and anti-siphonage pipe the axis branch of observation tube
Free end is higher than and the connection end of anti-siphonage pipe.
The course of work of the present utility model is：
When the liquid level in water-cooling tower is higher than setting position（The draining open height of drainpipe）When start Overflow drainage, current edge
Drainpipe, anti-siphonage pipe, U-shaped liquid sealing pipe flow into public blow-off line, when liquid level is reduced to the discharge outlet of drainpipe in water-cooling tower
During height, upper port of the air along anti-siphonage pipe enters drainpipe, prevents siphonage, in water-cooling tower liquid level no longer under
Drop；Now, still there is water in U-shaped liquid sealing pipe, it is U-shaped when the pressure balance in the pressure of this part water and public blow-off line
Liquid level in liquid sealing pipe no longer changes, and so as to keep the balance of hydraulic pressure in pressure and U-shaped liquid sealing pipe in public blow-off line, avoids
Pollutants in public blow-off line enter in water-cooling tower, prevent cross pollution, ensure the heat transfer effect of water-cooling tower；Pass through
Observation tube can be observed flooded conditions in water-cooling tower at any time；The purpose of the upper end bending of anti-siphonage pipe is prevented in air
Foreign matter is fallen into water-cooling tower.
The beneficial effects of the utility model are：
The setting of the utility model anti-siphonage pipe can effectively prevent the generation of siphonage, avoid liquid level in water-cooling tower excessive
Being reduced to water sucking mouth position causes water pump parking and the generation of space division system interlock shutdown phenomenon；The utility model is without manually doing
In advance, liquid level can be ensured automatically in the safe range of setting by U-shaped liquid sealing pipe, avoids water level is too high from causing dirty nitrogen in water-cooling tower
The drawbacks of entrance is blocked, and dirty nitrogen can not be discharged normally；And shared public blow-off line is realized, avoiding cross pollution
While, ensure water-cooling tower heat transfer effect.
Brief description of the drawings
Fig. 1 is water-cooling tower overflow mechanism schematic diagram in the prior art；
Fig. 2 is the utility model schematic diagram；
In figure mark for：Water-cooling tower 1, drainpipe 2, anti-siphonage pipe 3, U-shaped liquid sealing pipe 4, public blow-off line 5, observation tube
6th, stop valve 7.
Embodiment
Fig. 2 shows, a kind of space division system water-cooling tower automatic overflow device of the utility model, including drainpipe 2, anti-siphonage pipe
3rd, U-shaped liquid sealing pipe 4 and observation tube 6；The water sucking mouth of drainpipe 2 is located at the inside of water-cooling tower 1, and discharge outlet is located at outside water-cooling tower 1,
The discharge outlet of drainpipe 2 is connected with anti-siphonage pipe 3, and anti-siphonage pipe 3 is the straight tube of upper end bending, and upper port is higher than the row of drainpipe 2
The position at the mouth of a river, upper end bending can effectively prevent the impurity in air from entering by anti-siphonage pipe 3 in water-cooling tower 1；Anti-siphonage pipe 3
Lower port be connected with U-shaped liquid sealing pipe 4, the other end of U-shaped liquid sealing pipe 4 connects public blow-off line 5；The height of U-shaped liquid sealing pipe 4
When ensureing to be full of water in U-shaped liquid sealing pipe 4, hydraulic pressure is more than or equal to the pressure in public blow-off line 5；The middle part of anti-siphonage pipe 3
It is connected with observation tube 6, angle is acute angle between the axis of observation tube 6 and the axis branch of anti-siphonage pipe 3, the free end of observation tube 6（Open
Mouth end）Higher than the connection end with anti-siphonage pipe 3, ensure that openend is upward, facilitate eye-observation.
The course of work of the present utility model is：
When the liquid level in water-cooling tower 1 is higher than setting position（The draining open height of drainpipe 2）When start Overflow drainage,
Current flow into public blow-off line 5 along drainpipe 2, anti-siphonage pipe 3 and U-shaped liquid sealing pipe 4, when liquid level in water-cooling tower 1
When being reduced to the draining open height of drainpipe 2, upper port of the air along anti-siphonage pipe 3 enters drainpipe 2, prevents siphonage from sending out
Raw, liquid level no longer declines in water-cooling tower 1；Now, still there is water in U-shaped liquid sealing pipe 4, when pressure and the public blowdown of this part water
During pressure balance in pipeline 5, the liquid level in U-shaped liquid sealing pipe 4 no longer changes, so as to keep pressure and U in public blow-off line 5
The balance of hydraulic pressure in type liquid sealing pipe 4, avoid the Pollutants in public blow-off line 5 from entering in water-cooling tower 1, prevent from intersecting dirt
Dye, ensure the heat transfer effect of water-cooling tower 1；Flooded conditions in water-cooling tower 1 can be observed at any time by observation tube 6；Anti- siphon
