Description
Technical field
The invention belongs to the gas phase media water-sealed tank technical field of petrochemical industry low pressure drop, it is compound to relate generally to a kind of pipeline
Low pressure drop water sealed tank.
Background technology
At present, gas phase media big flow, big runner (pipe diameter ＞ 2m) conveying in petrochemical industry flue system
When, following pipeline cut-out technical method is usually taken：1st, large-scale stop valve.But large-scale stop valve presence design and manufacture difficulty,
The technical problems such as high temperature deformation bite is not easy to operate, the country not yet Related product occurs, it is necessary to import, thus expensive；2、
Large-scale regulating butterfly valve.There is the problems such as expensive, poorly sealed, heated yielding leakage in major diameter butterfly valve, so only permitting
Perhaps applied in the case of gas phase media leaks on a small quantity occasion or conduct emergency episode cutoff process；It is if tighter to seal request
Occasion, it is both needed to the cut-out measure for being aided with other good seals；3rd, traditional water sealed tank.Water sealed tank is cut-off means more common at present,
There is low easily manufacture, cost, good seal, do not leak, but traditional water sealed tank must be by the low-pressure vapor phase pipeline of major diameter
90 ° of arranged crosswises, and make gas phase media when being conveyed normal through it, carry out enlarging deceleration, dilatation, 180 ° of steerings, neckings
The processes such as acceleration, gas phase media is caused (to calculate normal through pressure loss during water sealed tank is big and measured result about pressure drop increases
5-8KPa), so as to directly influence the input of the conveying power of gas phase media or energy regenerating output, energy expenditure is added.For
Reduction pressure drop, designing unit often design the diameter (volume) of water sealed tank very big, and the cigarette for flowing through water sealed tank is reduced with this
Gas mean flow rate reduces pressure drop, and this directly results in device fabrication cost of transportation and be substantially increased again.The water sealed tank of major diameter simultaneously
Floor space itself is big, uneconomical.New water sealed tank is developed for this has realistic meaning.
In view of this, the present inventor is known based on such product design manufacture abundant for many years practical experience and specialty is engaged in
