Embodiment
Referring to Fig. 1, the import storehouse 1 that is provided with the binary check valve of boot section links to each other with gas transportation facilities such as range hood, outlet storehouse 2 connects gas emission pipe such as gas flue links to each other, between import storehouse 1 and the outlet storehouse 2 connecting port 3 is arranged, at aeration status not, connecting port 3 is by 4 sealings of the particular fluid media in the outlet storehouse 2.The particular fluid medium 4 in outlet storehouse is divided into boot section 5 and liquid storage area 6 by dividing plate 11, boot section 5 is at interval between connecting port 3 and liquid storage area 6, the flue gas that is flowed out by connecting port 3 is subjected to the restriction of dividing plate 11, can not with particular fluid medium 4 exchange energys in the liquid storage area 6.Particular fluid medium 4 on the dividing plate 11 of separation boot section 5 and liquid storage area 6 return port 9 arranged, so that can flow into boot sections 5 from liquid storage area 6 through return port 9.Particular fluid medium inlet 7 is located at outlet 2 tops, storehouse, and particular fluid medium position-limitting mouth 8 is located at the highest position of outlet storehouse restriction liquid level, establishes particular fluid medium flushing outlet 10 at the lowest part in outlet storehouse 2.
Working procedure:
When the binary check valve that is provided with the boot section need not discharged flue gas, because the pressure in the import storehouse 1 equals barometric pressure, particular fluid medium 4 sealing connecting ports 3, flue gas just can't blow back into import storehouse 1 from outlet storehouse 2, thereby has fabulous check performance.By adjusting the relative dimensions of connecting port 3, can obtain good resistance to compression check performance, see Fig. 1.
Referring to Fig. 2, when needs are discharged flue gas, because particular fluid medium 4 sealing connecting ports 3, after gas entered import storehouse 1, import storehouse 1 internal pressure raise immediately, and finally pushed the sealing that the particular fluid medium forms open, open connecting port 3, make flue gas can flow to outlet storehouse 2, arrow is the air-flow trend among the figure.When opening connecting port 3, flue gas is directly to contact with liquid in the boot section, they are formed pressure, under gas-static and viscous effect, particular fluid medium 4 in the boot section 5 is brought to liquid storage area 6, because the amount of the particular fluid medium 4 in the boot section 5 is limited, though return port is arranged, but because the less backflow of design seldom, under the working state that air-flow is constantly arranged, form a kind of transient equiliblium, just have only very a spot of particular fluid medium 4 in the boot section 5, for air-flow has been abdicated passage, like this, gas is through import storehouse 1, connecting port 3, boot section 5, outlet storehouse 2 enters the local resistance of vertical flue at last, in the boundary dimension of check valve hour, also can after a very short moment, quickly fall to very low, thereby make a large amount of flue gas bodies enter special vertical flue.
Simultaneously, in the boot section 5 very a spot of particular fluid medium 4 gas agitate down, produce many foams, these foams not only make greasy dirt can't be in the boot section place's accumulation such as 5, also wafing with gas accumulates the greasy dirt place easily to vertical flue wall, make greasy dirt vertically adhere to, to accumulate on the flue wall equally.Like this, the binary check valve that originally is provided with the boot section is under the acting in conjunction of physics, chemical action, and the function that Oil-gas Separation and environmental protection degrease continues to keep.
When the discharge flue gas stopped, the pressure in outlet storehouse 1 reduced gradually, and particular fluid medium 4 flows back to boot section 5 through return port 9, and finally seals connecting port 3 again.
Originally the employed particular fluid medium 4 of binary check valve that is provided with the boot section preferably has the solvent of cleaning action to oil smoke, regularly add, as washing agent etc.If but because economically, also available water adds as medium, the binary check valve that originally is provided with the boot section still can proper functioning.
After certain service time, regularly thoroughly discharge particular fluid medium 4 by particular fluid medium flushing outlet 10, thereby thoroughly cleaning is provided with the binary check valve of boot section, and upgrades particular fluid medium 4 fully.
Originally the binary check valve that is provided with the boot section also can be designed to structure shown in Figure 2, it is V-shaped with dividing plate 11 levels of liquid storage area 2 that it separates boot section 5, be arranged at the position relative with connecting port, because this particular design, when reducing gas-flow resistance, the air-flow of discharging to outlet storehouse 2 has an angle that makes progress, so that flue gas enters vertical flue.Fig. 4 is the phase diagram that this check valve air communication is crossed, and arrow is the air-flow trend.
Certainly, in order to adapt to special requirement of engineering, the shape of dividing plate and dividing plate can also have multiple design apart from the position of connecting port, can make the outlet storehouse obtain different air-flows and discharge angle, and make the binary check valve that originally is provided with the boot section adjust to needed state to the resistance of air-flow.
