Referring to fig. 2, the first embodiment of the pneumatic dual tank circulation system 200 of the present invention includes a dispersion device 21, an upper tank 22, a lower tank 23, a liquid level meter 27 and a heater 28.
The dispersing device 21 is adapted to disperse a liquid into a liquid mist. In the first embodiment, the dispersing device 21 is a high gravity rotating bed device.
The upper tank 22 is a closed tank, and the interior of the upper tank is in a vacuum low-pressure state, and includes an upper inlet 221, an upper port unit 220 and an upper outlet 224, wherein the upper inlet 221 is located at the upper end of the upper tank 22, the upper outlet 224 is located at the lower end of the upper tank 22, and the upper port unit 220 includes an upper inlet 223 communicated with the dispersing device 21.
The lower groove 23 is a closed groove, is located below the upper groove 22, and includes a lower vent unit 230, a lower liquid inlet 233, and a lower liquid inlet 234. The lower vent unit 230 is located at the upper end of the lower groove 23 and includes a lower air outlet 232. The lower liquid passage port 234 is located at the lower end of the lower tank 23. The lower port 234 is in communication with the dispersion device 21 and not via a pump.
The upper outlet 224 is connected to the lower inlet 233 of the lower tank 23 through a first valve 24, the lower outlet 232 is connected to the upper inlet 221 through a second valve 25, and the lower vent unit 230 is connected to gas through a third valve 26.
The first valve 24, the second valve 25 and the third valve 26 may be respectively selected from solenoid valves, pneumatic valves or manual valves, which may be the same or different.
The level gauge 27 is used to monitor the liquid level in the lower tank 23.
The heater 28 is used to heat the liquid flowing out of the lower liquid passage 234.
The specific operation of this first embodiment is as follows in a cyclic sequence:
(a) under the monitoring of the liquid level meter 27, when the liquid in the lower tank 23 needs to be dispersed, the first valve 24 and the second valve 25 are closed, the third valve 26 is opened, the gas is injected into the lower tank 23, so that the liquid in the lower tank 23 flows out of the lower liquid through port 234 by the pressure of the gas, and is pushed up and conveyed to the dispersing device 21 for dispersing. At this time, the gas does not flow to the upper inlet 221 due to the blockage of the second valve 25.
(b) Under the monitoring of the liquid level meter 27, when the liquid in the lower tank 23 is insufficient, the first valve 24 and the second valve 25 are opened, and the third valve 26 is closed, so that the gas in the lower tank 23 is pumped out from the lower gas outlet 232 through the vacuum low pressure of the upper tank 22 to reach the gas isobaric pressure in the upper tank 22 and the lower tank 23, and the liquid in the upper tank 22 flows out from the upper liquid outlet 224 through the lower liquid inlet 233 into the lower tank 23 through the gravity.
Referring to fig. 3, the second embodiment of the pneumatic dual tank circulation system 200 of the present invention is similar to the first embodiment, except that in the second embodiment, the lower tank 23 does not have a lower liquid inlet, the lower vent unit 230 further comprises a lower gas inlet 231, the lower gas inlet 231 is communicated with gas through a third valve 26, the upper liquid outlet 224 is communicated with a lower liquid through port 234 of the lower tank 23 through the first valve 24, and the heater 28 is used for heating the liquid flowing through the lower liquid through port 234 (i.e. the liquid flowing out of the lower liquid through port 234 and the liquid flowing out of the upper liquid outlet 224).
The specific operation of this second embodiment is as follows in a cyclic sequence:
(a) under the monitoring of the liquid level meter 27, when the liquid in the lower tank 23 needs to be dispersed, the first valve 24 and the second valve 25 are closed, the third valve 26 is opened, the gas is injected into the lower tank 23, so that the liquid in the lower tank 23 flows out of the lower liquid through port 234 by the pressure of the gas, and is pushed up and conveyed to the dispersing device 21 for dispersing. At this time, due to the obstruction of the first valve 24, the liquid flowing out of the lower liquid passing port 234 does not flow back to the upper liquid outlet 224; the gas does not flow to the upper inlet 221 due to the obstruction of the second valve 25.
(b) Under the monitoring of the liquid level meter 27, when the liquid in the lower tank 23 is insufficient, the first valve 24 and the second valve 25 are opened, and the third valve 26 is closed, so that the gas in the lower tank 23 is pumped out from the lower gas outlet 232 through the vacuum low pressure of the upper tank 22 to reach the gas isobaric pressure in the upper tank 22 and the lower tank 23, and the liquid in the upper tank 22 flows out from the upper liquid outlet 224 through the lower liquid through port 234 and flows into the lower tank 23 through the vacuum low pressure of the upper tank 22.
Referring to fig. 4, a third embodiment of the pneumatic dual tank circulation system 200 of the present invention is similar to the second embodiment, except that in the third embodiment, the dispersion device 21 is a dispersion nozzle and is located at the upper end of the interior of the upper tank 22, and the upper port unit 220 further includes an upper air outlet 222 located at the upper end of the upper tank 22.
