Embodiment
For further setting forth the utility model for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, its embodiment of formula water sealed tank, structure, feature, using method and effect thereof are gone out to the enterprising side according to a kind of secondary water seal that the utility model proposes, is described in detail as follows.
The technological scheme that the enterprising side of a kind of secondary of the utility model water seal goes out formula water sealed tank is: a kind of secondary water sealed tank, has a circle tube tank body, described circle tube tank body has suction tude, eccentric conical outlet, intake-outlet and flow-off; Suction tude is connected with upper inner core after entering circle tube tank body, and the bottom of upper inner core is one-level seal tank, and one-level seal tank is made up of shrouding bottom lower inner core upper end and one-level water seal urceolus and one-level water seal; Bottom and the sidepiece of lower inner core and cylinder type tank body form secondary seal tank; Suction tude, upper inner core, the central axis of lower inner core and the central axes of circle tube tank body; Intake-outlet is arranged on bottom circle tube tank body; Flow-off is then arranged on below air outlet.
Fig. 1 is the structural representation that the enterprising side of a kind of secondary of the utility model water seal goes out when formula water sealed tank is ventilated.Fig. 2 is the enterprising side of a kind of secondary of the utility model water seal structural representation when going out the water seal of formula water sealed tank.
As shown in Figure 1, a kind of enterprising side of secondary water seal goes out formula water sealed tank, has a circle tube tank body 3, described circle tube tank body 3 has suction tude 1, eccentric conical outlet 4, water intake 6 and flow-off 5.Suction tude 1 is connected with upper inner core 2 after stretching into circle tube tank body 3, and gas flows out to eccentric conical through the one-level runner I that upper inner core 2 rear portion gas is formed between upper inner core 2, lower inner core 7, one-level water seal shrouding 9 and one-level water seal urceolus 8 and exports 4 places.Another part gas then enters lower inner core 7 and flows out to eccentric conical from the secondary runner II formed between lower inner core 7, circle tube tank body 3 and exports 4; Two strands of gases of one-level runner I and secondary runner II flow out from eccentric conical outlet 4 after eccentric conical outlet 4 converges, and leave described water sealed tank.Intake-outlet 10 is arranged on bottom circle tube tank body 3; Flow-off 5 is positioned at below eccentric conical outlet 4.
When air inlet, gas enters after upper inner core 2 through inlet tube 1 and namely shunts, and a part of gas flows out through one-level runner I, takes full advantage of the upper space of described water sealed tank, and the diameter of lower inner core 7 can be reduced; Because the diameter of lower inner core 7 reduces, make the corresponding increase in gap between circle tube tank body 3 to lower inner core 7, when the secondary runner II of gas between circle tube tank body 3 and lower inner core 7 flows, flow velocity reduces, and resistance reduces, and pressure drop reduces; Wherein there is preferred proportion, i.e. D2/D1=0.6 ~ 0.99 with the ratio of the diameter D2 of lower inner core 7 in the diameter D1 of suction tude 1.Wherein preferred proportion is D2/D1=0.7 ~ 0.9, and optimal proportion is D2/D1=0.8.When giving vent to anger, gas leaves circle tube tank body 3, flows into eccentric conical outlet 4, exports after 4 rectifications, flow out described water sealed tank through eccentric conical; Export the air-flow after 4 rectifications through eccentric conical, flowing is more steady, and Biased flow phenomenon significantly alleviates, and the low velocity zone of the gas flow leaving described water sealed tank and recirculating zone are significantly reduced, and flow resistance alleviates, and the pressure loss reduces; Wherein there is preferred proportion, i.e. D4/D3=0.6 ~ 0.99 with the ratio of diameter D4 in the eccentric conical outlet diameter D3 of 4.Wherein preferred proportion is D4/D3=0.7 ~ 0.9, and optimal proportion is D4/D3=0.8.
When needing to block the gas phase media in described water sealed tank, open water intake 6 and intake-outlet 10, start water inlet, because the gaseous pressure of described water sealed tank air inlet side is high, side pressure of giving vent to anger is low, and described air inlet side and described side of giving vent to anger exist pressure difference, under gas phase differential pressure action, when the water entering described seal tank reaches balance liquid level, one-level seal tank A and secondary seal tank B all realizes effective sealing.When gas phase pipeline opened by needs, open intake-outlet 10, the water in seal tank flows out from intake-outlet 10, and now gas phase media enters from the suction tude 1 of described water sealed tank, flow out from eccentric conical outlet 4 through one-level runner I and secondary runner II, the gas piping passage in described water sealed tank is opened.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
