Specific embodiment
More specific detail is made to technical solution of the present invention below with reference to embodiment:
The present invention in high temperature and high pressure kettle in order to realize continuous bubbling, so the gas being passed through also must be high pressure gas, Otherwise gas is difficult to the gas for being passed into high temperature and high pressure kettle, and usually selling in the market and is generally stored with steel cylinder, highest Pressure, just must be to test when the gas pressure in steel cylinder is lower than pressure needed for testing in high temperature and high pressure kettle within 15MPa It carries out continuing to be pressurized with gas, just can guarantee that the gas in steel cylinder can be smoothly passed through in high temperature and high pressure kettle.It is continuous in order to realize It is bubbled, the exhaust relief valve in high temperature and high pressure kettle necessarily is in open state, and the flow for blasting gas depends on exhaust relief valve The degree of unlatching, unless the gas being passed through can generate in a short time with the rapid fully reacting of medium in kettle and without other gases, Otherwise it will lead to reacting kettle inner pressure raising, break ring reaction environment.Increasing can be used when being pressurized to test with gas for common lab Press pump carries out, and when industrialized mass production, the pressurization of test gas can be carried out using booster pump or compressor, but be not limited to This.
Required test gas in the high-temperature high-pressure reaction kettle 3 as shown in Figure 1:, passes through the first pressure reducing valve 17, preheater 16 Into supercharging equipment 18, low-pressure gas is become by high pressure gas by supercharging equipment 18, high pressure gas is flowed through the first check valve 11 Into surge tank 12, the high pressure gas in surge tank 12 enters high temperature through the second pressure reducing valve 6, second one-way valve 5, air intake control valve 4 In autoclave 3, extra gas is discharged through exhaust relief valve 1 in high temperature and high pressure kettle 3, during test, gas in surge tank 12 Pressure is higher than pressure in high temperature and high pressure kettle 3, and the pressure of gas output in surge tank 12 is adjusted by the second pressure reducing valve 6, and buffers 8 real-time monitoring of the pressure sensor buffering pressure inside the tank installed on tank 12, when pressure reaches setting pressure low value in surge tank 12 When supercharging equipment start, the tonifying Qi into surge tank 12, when in surge tank 12 pressure reach setting pressure high level when, supercharging equipment 18 It stops working, realizes continuous bubbling in high temperature and high pressure kettle 3 while extending 18 service life of supercharging equipment with this.
First pressure reducing valve 17 guarantees that the admission pressure of supercharging equipment 18 (booster pump) is stablized, and prevents high pressure gas from entering And supercharging equipment 18 is damaged, 16 purpose of gas preheater is the gas heating being pressurized to needs, prevents gas in pressurization Liquefaction damages supercharging equipment 18.
High pressure gas in supercharging equipment 18 is through the first check valve 11, and into surge tank 12, the first check valve 11 prevents from increasing When equipment 18 being pressed to shut down, high pressure gas rushes supercharging equipment 18 in surge tank 12, be equipped at the top of surge tank 12 pressure sensor 8, Temperature sensor 9 and safety valve 10, bottom are equipped with gas-liquid drain valve 13.
High pressure gas in surge tank 12 is passed through high temperature and pressure through the second pressure reducing valve 6, second one-way valve 5, air intake control valve 4 In kettle 3, the continuous bubbling in high temperature and high pressure kettle 3 is realized.By the second pressure reducing valve 6 between high temperature and high pressure kettle 3 and surge tank 12, The pressure for entering gas in high temperature and high pressure kettle 3 is adjusted, the flow of gas is controlled by exhaust relief valve 1, and then guarantees that high temperature is high Pressure in kettle 3 is pressed to stablize, second one-way valve 5 is set as preventing liquid suck-back the second pressure reducing valve 6 of damage during test gentle Rush tank 12.
The air intake control valve 4 and exhaust relief valve 1 are trace regulation type needle-valve or metering valve etc., can control gas Flow.
Since test is carried out under high-temperature and high-pressure conditions, the continuous tail gas that is discharged may result in solution loss in kettle, lead It causes solution concentration to increase, therefore is provided with condenser 2 between exhaust relief valve 1 and high temperature and high pressure kettle 3, guarantee tail gas in the same of discharge When, amount of solution is constant in high temperature and high pressure kettle.
Each transmission pipeline all has Insulation in above scheme, and shown surge tank 12 has heating and thermal insulation measure.
