In the present embodiment, described aspiration pump 17 is connected with supervisory control system of the prior art.
In the present embodiment, in order further to ensure the stable operation of evaporative cooling system, also can be standby for positive displacement pump 31 for increasing in drain line 39 second.In addition, because the utility model only has one for positive displacement pump 31, therefore only need standby one and supply positive displacement pump 31, and the patent No. is for having two in " 200910091705.8 " patent for positive displacement pump 31, if this patent increases stand-by pump, just need to increase by two.Therefore, compared with prior art, do not increasing or increasing standby confession under the situation of positive displacement pump 31, production cost of the present utility model is all well below prior art.
In the utility model, the confession discharge opeing process of described liquid supplying and draining device comprises the feed flow first after installing or having overhauled, automatic liquid supply and the discharge opeing in running, feed flow first after wherein installing or having overhauled comprises three kinds of feed liquid methods, for clear, respectively said process is elaborated below.
(1), install or overhauled after feed flow first.
Method 1: use for positive displacement pump 31 feed flows, first valve-off 9 37, valve 15, valve 6 32, valve 3 25 and valve 4 27, open all the other valves, coolant in the total tank 29 of liquid storage is by naturally flowing into transition fluid reservoir 30 for liquid header 38 and first for drain line 46, the 3rd liquid level gauge 34 on transition fluid reservoir 30 reaches while starting liquid level for positive displacement pump 31, for positive displacement pump 31, start, coolant in transition fluid reservoir 30 is pumped into evaporation-cooled device by second for drain line 39, owing to supplying the pump output to coolant of positive displacement pump 31 to be greater than the flow of the first coolant for drain line 46, so, the registration of the 3rd liquid level gauge 34 will decline, when being down to while stopping liquid level, for positive displacement pump 31, quit work, prevent for positive displacement pump 31 idle running, when the registration of the 3rd liquid level gauge 34 reaches startup liquid level again, again start for positive displacement pump 31 feed flows, so repeat, when the first liquid level gauge 13 readings reach predetermined fluid level, valve-off 11, when the second liquid level gauge 14 readings reach predetermined fluid level, valve-off 12, valve 1, valve 8 35, valve 7 33 and confession positive displacement pump 31, the total tank 29 of liquid storage continues to fill with liquid in transition fluid reservoir 30, when the reading of the 3rd liquid level gauge 34 approaches the highest liquid level, valve-off 16, valve 17 and valve 18, after the 3rd liquid level gauge 34 registrations are stable, valve-off 7 33 and valve 14.
Method 2: when cannot normally working for positive displacement pump 31, and in the time of can not changing in time, use vacuum pump 16 feed flows, first valve-off 1, valve 5 28, valve 6 32, valve 9 37, valve 10, valve 13 and valve 17, open all the other valves, with vacuum pump 16, the air in evaporation-cooled device pipeline is pumped, then valve-off 4 27 and vacuum pump 16, open valve 17.Because the air pressure in evaporation-cooled device pipeline is far below atmospheric pressure, so the coolant in the total tank 29 of liquid storage will be inhaled into evaporation-cooled device for drain line 46 by first.When the first liquid level gauge 13 readings reach predetermined fluid level, valve-off 11, valve-off 12 and valve 15 when the second liquid level gauge 14 readings reach predetermined fluid level.Then open valve 13, coolant flows into transition fluid reservoir 30 naturally.When the 3rd liquid level gauge 34 registrations approach predetermined value, valve-off 16, valve 17 and valve 18, after the 3rd liquid level gauge 34 registrations are stable, valve-off 7 33 and valve 14.In normal course of operation, valve 2 24, valve 5 28 and valve 8 35 are in normally open, valve 1, valve 3 25, valve 4 27, valve 6 32, valve 9 37, valve 15 and valve 18 are in normally off, and valve 7 33, valve 10, valve 11 and valve 12 are opened when fluid infusion.
Method 3: when supplying positive displacement pump 31 and vacuum pump 16 all cannot normally work and can not change in time, from valve 1, evaporation-cooled device is carried out to first feed flow.
(2) automatic liquid supply in running
In running, exhaust action can be discharged the part evaporative cooling medium steam in evaporation-cooled device, can reduce the amount of coolant in cooling circuit, so need the liquid level of coolant in Real-Time Monitoring cooling circuit in running.If the output valve of the first liquid level gauge 13 is during lower than fluid infusion liquid level, for positive displacement pump 31, start, and open valve 7 33, valve 10 and valve 11, coolant in transition fluid reservoir 30 is pumped to the first liquid collecting endless tube 7 and stator bar heater 2 etc., when the first liquid level gauge 13 readings reach predetermined fluid level, for positive displacement pump 31, valve 7 33, valve 10 and valve 11, close, system completes automatic liquid supply one time.If the output valve of the second liquid level gauge 14 is during lower than fluid infusion liquid level, for positive displacement pump 31, start, valve 7 33, valve 10 and valve 12 are opened, coolant in transition fluid reservoir 30 is pumped to, the second liquid collecting endless tube 8 and collector ring heater 3 etc., when the second liquid level gauge 14 readings reach predetermined fluid level, valve 7 33, valve 10 and valve 12 are closed, and for positive displacement pump 31, close, and system completes automatic liquid supply one time.If the 3rd liquid level gauge 34 during lower than fluid infusion liquid level, utilizes the total tank 29 of liquid storage and for liquid header 38 to 30 fluid infusion of transition fluid reservoir.
(3) discharge opeing
When evaporation-cooled device needs discharge opeing, valve-off 2 24, valve 6 32, valve 10 and valve 14, open all the other valves, coolant in evaporation-cooled device pipeline is back to transition fluid reservoir 30 by first for drain line 46, when the 3rd liquid level gauge 34 registrations reach discharge opeing liquid level, start for positive displacement pump 31, coolant is pumped into the total tank 29 of liquid storage by total liquid back pipe 36, because the flow that pumps for 31 pairs of coolants of positive displacement pump is greater than the first flow for coolant in drain line 46, so, the 3rd liquid level gauge 34 registrations will decline, when being down to while stopping discharge opeing liquid level, for positive displacement pump 31, quit work, to prevent 31 idle running of supply and discharge liquid pump, when the 3rd liquid level gauge 34 registrations reach discharge opeing liquid level again, again start for positive displacement pump 31 discharge opeings, so repeat, until medium is discharged totally.
In the present invention, the course of work of described vapour-recovery unit is: the steam pressure in balance pipe 1 is during higher than 0.06MPa, electromagnetically operated valve 26 and aspiration pump 17 leave, and in cooling circuit, unnecessary steam is drawn into the second condenser 18, and steam is aggregated into liquid, tail gas enters filter 19, entrained steam is aggregated into liquid, and filter 19 tail gas enter water tank 21, finally enter air, when in balance pipe 1, pressure is lower than the opening pressure of electromagnetically operated valve 26, electromagnetically operated valve 26 and aspiration pump 17 are closed.Valve 3 25 is hand by-pass valve, when electromagnetically operated valve 26 cannot normally be opened, by manual unlocking valve 3 25, carries out exhaust.
