Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
With reference to shown in Fig. 1, a kind of boiling cryogen purifier, building block mainly include liquid injection port 1, ball valve 2,
Coarse filter 3, fine filter 4, magnetic drive pump 5, liquid level gauge 6, pressure gauge 7, safety valve 8, temperature sensor 9, pressure sensor 10, condensation
Device 11, transparent water tank 12, evaporator 13, cleaning service ports 14, heating chamber 15, heater 16, vacuum compressor 17, collecting tank
18th, several components such as drier 19, leakage fluid dram 20.
With reference to shown in Fig. 2, the operating procedure of boiling cryogen purifier is：Vacuumize-fluid injection-filtering-heating-evaporation-
Condensation-collection-drying-discharge opeing.
Since tank body is higher, it is not easy to pour into evaporator 13 using toppling over the mode cryogen that will seethe with excitement, while topple over and can also make
Largely volatilize into cryogen；If being injected according to pump, by whole discharges, discharge while, will carry substantial amounts of for air in tank body
Refrigerant vapor comes out, and causes damages, while causes environmental hazard.
The cryogen purifier that seethes with excitement is injected boiling cryogen in evaporator 13 by the way of vacuum pumping liquid injection, vacuumizes note
Liquid the purpose is to reduce volatilization, make cryogen full of evaporator 13, it is necessary to which the boiling cryogen of purification is noted by way of vacuum liquid filling
Enter in evaporator 13, first turn on vacuum compressor 17, the pressure of whole system is evacuated to below -0.05MPa, by liquid injection port 1
It is placed in the container for holding cryogen, opens V01 valves, under atmospheric pressure, cryogen can be automatically drawn into evaporator 13
In.
After the completion of imbibition, the magnetic drive pump 5 below evaporator is opened, cryogen will enter filter under the action of magnetic drive pump 5
Circulating filtration is carried out, the fine filter 4 has three and parallel connection, may filter that the solid particle polluter in cryogen, can first use
One of filter, if filter element blocks, reuses other filters.4 liang of the coarse filter 3 or/and fine filter
End is respectively arranged with valve, after the completion of equipment clean, closes the valve at plugged sereen both ends, cleaning or replacement filter
Filter core.
Seethe with excitement cooling water of the cryogen purifier by 13 bottom of heating evaporation tank, and indirectly heat boiling cryogen, is allowed to become
Into steam.It is steady to can ensure that temperature rises, evaporation rate is controllable, avoids the occurrence of too fast, the danger of hypertonia in tank body of seething with excitement
Situation.
Due to cooling water boiling point be 100 DEG C, if 15 body of heating chamber heating it is too fast, cooling water will seethe with excitement, make temperature will not on
Rise too fast.
Safety valve 8 is set at the top of evaporator, if hypertonia in tank body, safety valve 8 can timely pressure release.Evaporator lower part is set
Cleaning service ports 14 are put, if necessary, operating personnel, which can enter in tank body, carries out cleaning maintenance work.
Drier 19 can remove the moisture content in boiling cryogen, and boiling cryogen flows through drier 19 during discharge opeing, is just done
It is dry.
After the completion of imbibition, the magnetic drive pump 5 of the lower section of evaporator 13 is opened, cryogen will enter refined filtration under the action of magnetic drive pump 5
Device 4 carries out circulating filtration.
Pressure gauge 7 is installed, 18 tank wall of collecting tank is provided with liquid level gauge 6, refrigerant vapor on the evaporator 13
Liquid is condensed into the cold after into the condenser 11 at the top of collecting tank 13, is flowed into collecting tank 18, is passed through 6 observable tank body of liquid level gauge
Interior liquid level.
With reference to shown in Fig. 3, before heating, cooling water should be passed through into condenser 11, cooling water temperature should at least be boiled than cryogen
Point temperature is more than 10 DEG C low.Also pure water should be added before heating into transparent water tank 12, it should be ensured that the water level in transparent water tank 12
Higher than minimum.Opening electric heater 16, heats the pure water in heating chamber 15, after cooling water heating, will pass through tank
Cryogen in body heating evaporation tank 13, after cryogen reaches boiling point, gasifies opening, and pressure increase in evaporator 13, steam will be logical
The pipeline of pervaporation tank top enters condenser 11.
18 liquid level of collecting tank no longer rises, and shows that liquid has been entirely vaporized in evaporator 13, observes pressure in tank body, if
Pressure is more than 0, places container in leakage fluid dram 20, opens 20 valve of leakage fluid dram, collecting tank 18 under the action of pressure inside the tank
Middle liquid will pass through drier 19, be discharged from leakage fluid dram 20.If pressure is 0 in tank body, liquid is not then exhausted from, and can open collecting tank
18 bottom magnetic drive pumps 5, liquid is discharged under the action of magnetic drive pump 5 from leakage fluid dram 20 in collecting tank 18.Place and divide in drier 19
Son sieve drier, can remove the moisture content in cryogen, drier 19 needs to regularly replace.Can be by removing the flange at the top of drier 19
Lid, replaces the drier in drier 19.
Purifier installs 4 temperature sensors 9 and a pressure sensor 10 altogether.Install one in 15 body bottom of heating chamber
Temperature sensor 9, for measuring cooling water temperature in evaporation cavity, if water temperature over-high is, it is necessary to stop heating.13 bottom of evaporator
One temperature sensor 9 is installed, for measuring the temperature of evaporation pot bottom cryogen.One temperature sensing of the top of evaporator 13 installation
Device 9, for measuring refrigerant vapor temperature, also installs a pressure sensor 10, for measuring pressure in tank body at the top of evaporator.
One temperature sensor 9 of the top of collecting tank 18 installation, for measuring the temperature in evaporator, if temperature is excessive in collecting tank 18,
Illustrate that outer cooling water flow is too low or cooling water temperature is excessive, should check the state of cooling water, it is ensured that purifier safe operation.
