With the suction of the opposite side of liquid circulation pump 55 tell truth 57 and the 3rd path 63 that is connected of the outlet valve 62 of liquid outlet 61 on, be provided with the 3rd check valve 64.
The exhaust that is communicated with the gas collection portion 53 and the air exit 65 of knockout drum 48 is provided with exhaust controlled valve 67 with on the path 66.This exhaust is the automatic switch valves that path automatically switched to the electromagnetic start formula of path opening state by closed condition according to the liquid level dropping signal that liquid-level switch 52 detects with controlled valve 67.
Secondly, the effect to the enforcement state of Figure 1 and Figure 2 is illustrated.
Fig. 1 shows the state of degassing running, closes and cut off exhaust with in the path 66 at the controlled valve 67 that exhaust is used, and liquid circulation pump 55 beginnings of the type that two-way circulates are just changeed, and knockout drum 48 sides become the suction side of pump.
When this degassing running, the suction decompression power of liquid circulation pump 55 acts on flow control valve 47 by knockout drum 48, therefore, be inhaled into the liquid of flow control valve 47 the molten gas of depositing through check valve 44 from the inlet valve 42 of liquid inlet 41 and be the bubble state separate out between flow control valve 47 and knockout drum 48, this promptly is so-called deaeration.
After this molten bubble of depositing gas enters knockout drum 48, separate release, do not enter liquid circulation pump 55 at bottom liquid collecting portion 51 relative gas collection portion 53 places, top.Therefore, can not take place that the bubble of separating out from liquid is low in the inlet capacity that has often by pump, cavitation erosion and problem such as dissolving again.
The liquid through deaeration that spues from liquid circulation pump 55 is cut off in second check valve 46, simultaneously, flows out from liquid outlet 61 dischargings via the 3rd check valve 64.
Simultaneously, along with the gathering of gas in knockout drum 48, liquid level descends, when liquid-level switch 52 detects condensed gas and forces liquid level to drop to critical liquid level, as shown in Figure 2, then running is switched to the exhaust operating condition of discharging gas in the knockout drum jar according to its signal immediately.
Exhaust running shown in Figure 2 according to above-mentioned switching signal, switches to the path opening state with opening and closing valve 67 paths by closed condition with above-mentioned exhaust automatically.Meanwhile, the type that two-way circulates liquid circulation pump 55 also automatically switches to counter-rotating by just changeing, and is connected side draught 56 exhaust ends that also automatically switched to pump by the suction side of pump of telling truth with the knockout drum 48 of liquid circulation pump 55 joins.
At this moment, the suction of liquid circulation pump 55 opposite sides 57 discharge openings by pump of telling truth switch to pump intake, therefore, second check valve 46 of the suction of liquid circulation pump 55 on alternate path 45, liquid is sucked in the liquid circulation pump 55 through second check valve 46 by the inlet valve 42 of liquid inlet 41, the liquid that spues through liquid circulation pump 55 is fed to knockout drum 48 bottoms, and the liquid level in the knockout drum 48 is risen.
Therefore, be gathered in the gas at gas collection portion 53 places of knockout drum 48,, be forced to outside exhaust channel 66 drain tanks through having the switching valve 67 that switches to the path opening state by upwards pushing of the liquid level that rises in the knockout drum 48.
Like this, utilize and shared liquid circulation pump 55 feed flow in knockout drum 48 of degassing running, make hermetic type knockout drum 48 return to the start of run state.
In a word, the degasser of the enforcement state of Figure 1 and Figure 2 comprises, one two-way circulation type liquid circulation pump 55, it when it is just changeing suction inlet, be that a side draught of discharge opening tells truth 56 and be discharge opening when just changeing during counter-rotating, during counter-rotating another side draught of suction inlet 57 Hes of telling truth, 41 to a side draught of liquid circulation pump 55 first path, 43 Hes that 56 places are provided with of telling truth in the liquid inlet, 41 to another side draught of liquid circulation pump 55 alternate path 45 Hes that 57 places are provided with of telling truth in the liquid inlet, in another side draught of liquid circulation pump 55 57 the 3rd path 63 Hes that are provided with to liquid outlet 61 places of telling truth, first path 43 is provided with flow control valve 47 Hes, flow control valve 47 a to side draught of liquid circulation pump 55 is told truth and is provided with between 56 under decompression state as knockout drum 48 Hes of gas-liquid separation device with gas and fluid separation applications, first, the second and the 3rd path 43,35, be respectively arranged with on 63, only allow liquid from the 41 a plurality of check valve 44 that flow to liquid outlet 61 directions through liquid circulation pump 55 that enter the mouth, 46,64 Hes, the exhaust of gas breakdown when the gas collection portion 53 of knockout drum 48 discharges is with opening and closing valve 67, by type liquid circulation pump 55 and a plurality of check valve 44 of two-way circulating, 46,64 distinctive combination, do not use expensive automatic three-dimensional valve, can by knockout drum 48 implement degassing operation and, the exhaust operation that the gases assembled in the knockout drum 48 is emitted by degassing running.
Secondly, Fig. 3 so that shown in Figure 5 be other example of the present invention.In addition, use same-sign, omit the explanation of this part at this in the part that the example of Figure 1 and Figure 2 is identical.
As shown in Figures 3 and 4, the type that two-way circulates liquid circulation pump 55 is provided with and is a side draught that suction inlet, counter-rotating the time be discharge opening 56 and that tell truth when just changeing, another side draught that is suction inlet when being discharge opening, counter-rotating when just changeing tells truth 57, liquid inlet 41 to the suction of a side of liquid circulation pump 55 is told truth and is provided with first path 43 between 56, liquid inlet 41 to the suction of the opposite side of liquid circulation pump 55 is told truth and is provided with alternate path 45 between 57, and the suction of the opposite side of liquid circulation pump 55 tells truth 57 to being provided with the 3rd path 63 between the liquid outlet.
This gas-liquid separation device 48, have be connected, remove the gas in the liquid with flow control valve 47 and make it agglomerateization degassing tank 48a and, make the gas of agglomerateization among the degassing tank 48a be located away from hermetic type knockout drum 48b on the liquid level, be provided with first check valve 44 in first path 43 between degassing tank 48a and the knockout drum 48b.
In first, second and third path 43,45,63, be respectively equipped with only allow liquid from the liquid inlet 41 check valve 44,46 and 64 that flow to liquid outlet 61 by liquid circulation pump 55, exhaust is provided with the exhaust usefulness controlled valve of opening 67 when the gas collection portion 53 of gas-liquid separation device 48 discharges gases with path 66.
In addition, liquid is the electromagnetic start formula automatic switch valves that the path blockade state automatically switched to the path opening state according to the liquid level dropping signal that liquid-level switch 52 detects with controlled valve 49.
Shown in Fig. 5 (a), degassing tank 48a is made of with filler 72 the jar body 71 and the promotions degassing that is filled in jar body 71.Filler 72 is the irregular charges with the lineament of metals such as stainless steel, titanium alloy, nickel making.
Simultaneously, rely on the pressurization of control valve 47 and the suction of liquid circulation pump 55, degassing tank 48a and knockout drum 48b are depressurized simultaneously, therefore under this decompression state, shown in Fig. 5 (b), the liquid 73 that enters in the degassing tank 48a body 71 contacts with charges 72, can make the gas of separating in the liquid 73 74 in the efficient degassing in filler 72 surfaces.
In addition, because the gas 74 that takes off from liquid 73 among the degassing tank 48a forms big gas agglomerate, and is located away from the liquid level rapidly, thereby can make the reduced of knockout drum 48b in knockout drum 48b.
Relative therewith, as not being set, degassing tank 48a only uses knockout drum 48b, the gas that produces in the knockout drum 48b under the decompression is micro air bubble, the separating rate that gas is located away from the liquid is slow, the rise speed of the separation on liquid level of the gas of generation slows down in the decompression knockout drum 48b down, and the flow velocity of the liquid that moves of must slowing down in jar just can make gas separate fully with liquid, so have to strengthen the slow down flow velocity of pot liquid of the diameter of knockout drum 48b.
Below, just Fig. 3 describes to the effect of example shown in Figure 5.
State for degassing running shown in Figure 3, liquid is opened with controlled valve 49 it is communicated with first path 43, and exhaust channel 66 is closed and cut off to exhaust with controlled valve 67, in this simultaneously, the type that two-way circulates liquid circulation pump 55 is just changeing, and makes knockout drum 48b side become the suction side of pump.
In this degassing running, suction decompression masterpiece is used for degassing tank 48a and the knockout drum 48b between the circulating pump 55 of the flow control valve 47 of control fluid flow and suction liquid, therefore, survival gas is bubble and is separated out (being deaeration) from the inlet valve 42 of liquid inlet 41 is inhaled into the liquid of degassing tank 48a via controlled valve 49 and flow control valve 47.
Enter the liquid 73 of degassing tank 48a and contacting of filler 72 by decompression, on filler 72 surfaces, gas 74 can be removed from liquid 73 effectively.The gas of being deviate from from liquid 73 in knockout drum 48a 74 is that bubble shape is separated out with air mass.
Above-mentioned bubble is in the state of sneaking among the liquid and enters knockout drum 48b via first check valve 44 1, will separatedly be released to the gas collection portion 53 on liquid collecting portion 51 tops, does not enter liquid circulation pump 55.Therefore, low, cavitation erosion of the inlet capacity that by pump the time, causes of the bubble that does not take place usually to separate out and problem such as dissolving again from liquid.
The liquid of deaeration that spues from liquid circulation pump 55 is discharged by liquid outlet 61 via the 3rd check valve 64 when being cut off by second check valve 46.
On the other hand, along with the gathering of gas in knockout drum 48b, liquid level descends, and liquid-level switch 52 sends signal when a large amount of air accumulations makes liquid level drop to the limit detecting, and makes knockout drum 48b shown in Figure 4 switch to the exhaust operating condition.
Exhaust running as shown in Figure 4, the liquid level decline detection signal that sends according to above-mentioned liquid-level switch 52, liquid automatically switches to the path blockade state with controlled valve 49 by the path opening state, and exhaust is changed to the path opening state with controlled valve 67 automatically by the path blockade state.Meanwhile, the type that two-way circulates liquid circulation pump 55 automatically switches to counter-rotating by just changeing, and the suction that is connected with the knockout drum 48 at liquid circulation pump 55 places is told truth and 56 automatically switched to the pump exhaust end by the pump suction side.
At this moment, another side draught of liquid circulation pump 55 is told truth and 57 is switched to Pump Suction Nozzle by the pump discharge opening, so second check valve 46 of suction in alternate path 45 of liquid circulation pump 55, liquid is inhaled in the liquid circulation pump 55 through second check valve 46 by the inlet valve 42 of liquid inlet 41, the liquid that spues from liquid circulation pump 55 enters the bottom of knockout drum 48b, and the liquid level in the knockout drum 48b is risen.
Therefore, be gathered in the gas of knockout drum 48b gas collection portion 53,, be forced to via the exhaust that has the controlled valve 67 that switches to opening state with outside path 66 drain tanks by upwards pushing of the liquid level that rises in the knockout drum 48b.
When this exhaust running, the suction pressure of liquid circulation pump 55 does not influence degassing tank 48a by the effect of controlled valve 49, and the pressure that spues of liquid circulation pump 55 does not influence degassing tank 48a by the effect of first check valve 44 yet.
And shared liquid circulation pump 55 feed flow in knockout drum 48b when utilizing with degassing running can make hermetic type knockout drum 48b return to the start of run state thus.
Like this, the two-way circulate specific combination of type liquid circulation pump 55 and a plurality of check valve 44,46 and 64 of employing, even need not expensive automatic three-dimensional valve, also can realize degassing tank 48a and knockout drum 48b efficient degassing running and, the exhaust running that the gas that utilizes degassing running to make to assemble in the knockout drum 48b is discharged.
Particularly, gas-liquid separation device 48 have the degassing tank 48a that removes the gas in the liquid and make it agglomerateization and, the gas of agglomerateization among the degassing tank 48a is located away from knockout drum 48b on the liquid level, the gas of deviating from from liquid in degassing tank 48a forms big air mass, after this air mass enters knockout drum 48b with liquid, air mass rises rapidly in knockout drum 48b, be located away from liquid level efficiently, therefore with do not add degassing tank 48a and compare, not only can dwindle the diameter of knockout drum 48b, can also accelerate the flow velocity in the knockout drum 48b, improve degassing efficiency.
Simultaneously, liquid level dropping signal according to the detection of liquid-level switch 52, liquid circulation pump 55, liquid automatically switch with controlled valve 67 with controlled valve 49 and exhaust, realized the automatic switchover between degassing running and exhaust running, and, can also reduce the fault rate of automatic valve owing to do not use automatic three-dimensional valve.
As described above, one example and another example, peculiar combination by two-way circulate type liquid circulation pump and a plurality of check valve, do not use expensive three-dimensional automatic valve, can realize relying on gas-liquid separation device degassing running and, will accumulate in the exhaust running that the gas in the knockout drum is discharged by degassing running.
The specific combination that the liquid circulation pump that dependence is two-way circulated and a plurality of check valve constitute, the degassing that can not use expensive automatic three-dimensional valve to carry out gas-liquid separation device turn round and will accumulate in the exhaust running that the gas in the knockout drum is discharged by degassing running.
By the peculiar combination of two-way circulate type liquid circulation pump and first, second and third check valve, need not expensive automatic three-dimensional valve reach with identical in the past knockout drum under degassing running and will accumulate in the exhaust running that the gas in the knockout drum is discharged by degassing running.
By liquid-level switch detection of liquid level decline situation, liquid circulation pump and the exhaust automatic switchover of controlled valve, the automatic switchover that running and exhaust turn round can outgas, this is external when having omitted automatic three-dimensional valve, the quantity of automatic switch valve has been reduced to bottom line, thereby the fault rate that the control automatic switch valve causes drops to bottom line.
The specific combination that constitutes by the liquid circulation pump that two-way circulates and a plurality of check valve, do not use expensive automatic three-dimensional valve, realize by gas-liquid separation device outgas efficiently running and, degassing running exhaust that the gas assembled in the gas-liquid separation device is discharged is turned round thus.
Particularly, gas-liquid separation device have remove gas in the liquid and the degassing tank that makes it to assemble and, be located away from knockout drum on the liquid level with accumulating in gas in the degassing tank, the gas that removes the liquid in degassing tank forms big agglomerate, after agglomerate that this is big and liquid enter knockout drum simultaneously, air mass in the knockout drum rises rapidly and efficiently separates from liquid level, therefore not only can dwindle the diameter of knockout drum, and can accelerate the interior flow rate of liquid of knockout drum, improve degassing efficiency.
By the pressurization of pressure regulating mechanism and the suction of liquid circulation pump the liquid in the post-decompression degassing tank is contacted with filler, can make the efficiently degassing in the gas from liquid on the filler surface.
Liquid circulation pump, liquid automatically switch according to the liquid level dropping signal that liquid-level switch sends with controlled valve with controlled valve and exhaust, the switching of degassing running and exhaust running is carried out automatically, and, owing to omitted automatic three-dimensional valve, can suppress the fault rate of automatic valve.
