Description
Technical field
The utility model belongs to the gas phase media water-sealed tank technical field of petrochemical industry low pressure loss, relates generally to a kind of water sealed tank of reducing and expansion formula.
Background technique
At present, when the large flow of gas phase media, large runner (pipe diameter > 2m) are carried in petrochemical industry fume pipe system, conventionally take following pipeline to cut off technological method: 1, large-scale stop valve.But large-scale stop valve exists and manufactures and designs the technical problems such as difficulty, high temperature deformation bite be not easy to operate, and the domestic Related product that not yet occurs, needs import, thereby expensive.2, large-scale regulating butterfly valve.Expensive, poorly sealed, the problems such as yielding leakage of being heated that major diameter butterfly valve exists, so only in the case of allowing a small amount of occasion of leaking of gas phase media or cutting off processing and apply as emergency episode; If to the tighter occasion of seal request, all need to be aided with the cut-out measure of other good seal.3, traditional water sealed tank.Water sealed tank is current more conventional cut-out means, have that easy manufacture, cost are low, good seal, the advantage such as do not leak, but traditional water sealed tank must be by 90 ° of intercross arrangement of large diameter low-pressure vapor phase pipeline, and make gas phase media when normally carrying by it, the processes such as enlarging deceleration, dilatation, 180 ° turn to, reducing acceleration have been carried out, the pressure loss large (calculating and the about pressure drop increase of measured result 5-8kPa) while causing gas phase media normally by water sealed tank, thereby the transmitting power input or the energy that directly have influence on gas phase media reclaim output, have increased energy consumption.The water sealed tank of development of new has realistic meaning for this reason.
Model utility content
The purpose of this utility model is to propose a kind of water sealed tank of reducing and expansion formula, in the sealing of water sealed tank more tightly, on more reliable basis, reduce water sealed tank pressure drop, reduces operating cost simultaneously.
The utility model completes the technological scheme that its invention task takes:
The water sealed tank of reducing and expansion formula, has a circle tube tank body, has suction tude, steam outlet pipe, intake-outlet and flow-off on described circle tube tank body; Suction tude was carried out dwindling of a diameter before entering circle tube tank body, the central axis of suction tude and the central axes of circle tube tank body; Steam outlet pipe carries out the expansion of a tank body leaving tank body place, and the central axis of steam outlet pipe is vertical with the central axis of circle tube tank body; Intake-outlet is arranged on circle tube tank body bottom; Flow-off is arranged on steam outlet pipe below.
The utility model proposes, adopt the beneficial effect of technique scheme to be:
1, pressure drop is little, and operating cost is low.
The utility model has been broken through the structure of traditional water sealed tank, and the design of its import undergauge and outlet hole enlargement makes that gas phase flow line is more smooth and easy, the pressure loss is little, reduces the power consumption of main air blower long-time running, has reduced operating cost.Through blowing experiment, water sealed tank pressure drop is 350 Pa left and right only, are about 1/8～1/10 of traditional water sealed tank, and energy-saving effect is very remarkable.
2, sealing is tight.
Compared with other seal valve, butterfly valve seal more tightly, more reliable.Can adapt to different gas phase media, as the medium such as poisonous, inflammable.
Accompanying drawing explanation
Fig. 1 and Fig. 2 are the utility model structural representations.
In figure, each numbering is described as follows: 1, suction tude 2, air inlet reducing pipe 3, circle tube tank body 4, the expansion tube 5 of giving vent to anger, steam outlet pipe 6, intake-outlet 7, flow-off.
Embodiment
With embodiment, the utility model is illustrated by reference to the accompanying drawings:
As depicted in figs. 1 and 2, a kind of water sealed tank of reducing and expansion formula, has a circle tube tank body 3, has suction tude 1, air inlet reducing pipe 2, the expansion tube 4 of giving vent to anger, steam outlet pipe 5, intake-outlet 6 and flow-off 7 on described circle tube tank body 3.Suction tude 1 and air inlet reducing pipe 2 are arranged on top one side of circle tube tank body, and gas enters circle tube tank body 3 by air inlet reducing pipe 2 after suction tude 1 undergauge; Give vent to anger expansion tube 4 and steam outlet pipe 5 is positioned at the sidepiece of circle tube tank body, and gas enters steam outlet pipe 5 in outlet port after the expansion tube 4 of giving vent to anger; Intake-outlet 6 is arranged on circle tube tank body bottom; Flow-off 7 is positioned at expansion tube 4 belows of giving vent to anger.
When air inlet, gas enters circle tube tank body 3 by air inlet reducing pipe 2 after suction tude 1 undergauge; Because the volume of suction tude entirety reduces, make the corresponding increase of volume of circle tube tank body 3, gas is more smooth flowing of circle tube tank body, and resistance reduces, and pressure drop reduces; There is optimal proportion, i.e. D2/D1=0.8～0.85 in the ratio of the diameter D1 of suction tude 1 and the diameter D2 of air inlet reducing pipe 2 wherein.When giving vent to anger, gas leaves tank body through the expansion tube 4 that increases diameter by steam outlet pipe 5; During due to outlet, the diameter of tracheae increases, and makes gas enter air outlet reducing ratio by circle tube tank body 3 and reduces, and flows more smooth and easy, and resistance reduces, and pressure drop reduces; Wherein give vent to anger the diameter D3 of expansion tube 4 and the diameter D4 of steam outlet pipe 4 ratio exist optimal proportion, i.e. D4/D3=0.75～0.8.
When needs block gas phase media, open intake-outlet 6, start water inlet, because the gaseous pressure of water sealed tank air inlet side is high, the side pressure of giving vent to anger is low, and air inlet side and the side of giving vent to anger exist pressure difference, under gas phase differential pressure action, the water that enters water sealed tank reaches balance liquid level, realizes effective sealing effect, when needs are opened gas phase pipeline, open intake-outlet 6, the water in water seal tank body flows out from intake-outlet 6, and now gas phase media enters from the suction tude 1 of water sealed tank, from steam outlet pipe 5, flow out, pipeline is opened.
For on-the-spot actual conditions, the utility model proposes two kinds of hole enlargement forms in outlet port:
1, the dried up sealed cans distance of on-the-spot pipeline, adopts water sealed tank structure 1(Fig. 1): the expansion tube 4 of giving vent to anger in this structure is longer, is connected by cone section with steam outlet pipe 5.
2, the dried up sealed cans near distance of on-the-spot pipeline, adopts water sealed tank structure 2(Fig. 2): in this structure, directly adopt cone section to connect circle tube tank body 3 and steam outlet pipe 5.
