Thus, the existing organic amine calibration technology has certain organic amine species limitations, and the occurrence mode is single, which makes it difficult to achieve the calibration of multiple organic amine species.

[0026] Specifically, Figure 1It is a block diagram of a device for calibrating various types of organic amine gases according to an embodiment of the present application.

[0027] like Figure 1 As shown, the multi-type organic amine gas calibration device 10 includes: a first organic amine gas generating unit 101 , a second organic amine gas generating unit 102 , a third organic amine gas generating unit 103 and a calibration module 104 .

[0028] The first organic amine gas generating unit 101 is used to generate a first type of organic amine gas that meets the concentration requirement of the target gas generator (ie, the organic amine gas cylinder) 1 .

[0029] The second organic amine gas generating unit 102 is used to generate a second type of organic amine gas that meets the concentration requirement of the target gas permeation rate control unit (ie, the organic amine permeation tube).

[0030] The third organic amine gas generating unit 103 is used to generate a third type of organic amine gas that meets the concentration requirement of the target organic amine liquid.

[0031] The embodiment of the present application can firstly utilize the gas generator 1, the gas permeation rate control unit and the preset liquid generating unit 8 to respectively generate a first type of organic amine gas with a high concentration that meets the concentration requirements corresponding to the target gas generator 1, a second type of organic amine gas that meets the concentration requirements corresponding to the target gas permeation rate control unit, and a third type of organic amine gas that meets the concentration requirements corresponding to the target organic amine liquid.

[0032] Optionally, in one embodiment of the present application, the multi-type organic amine gas calibration device 10 of the embodiment of the present application further includes: a pipeline, an electronic three-way valve, a pipeline heating device and a gas flow control generator.

[0033] Among them, the pipeline is used to transmit organic amine gas.

[0034] The electronic three-way valve is used to switch the first organic amine gas generating unit, the second organic amine gas generating unit and the third organic amine gas generating unit to generate corresponding organic amine gases.

[0035] The pipeline heating device is used to heat the pipeline to a target temperature.

[0036] The gas flow control generator (ie, mass flow controller) is used to generate the first type of organic amine gas, the second type of organic amine gas, and the third type of organic amine gas at target flow rates.

[0037] In addition, the various organic amine gas calibration device 10 of the embodiment of the present application further includes a pipeline, an electronic three-way valve, a pipeline heating device and a gas flow control generator.

[0038] Among them, the pipeline can transmit the corresponding organic amine gas; secondly, the embodiment of the present application has three electronic three-way valves, which can automatically control the switching of the first organic amine gas generating unit 101, the second organic amine gas generating unit 102 and the third organic amine gas generating unit 103 to generate the corresponding organic amine gas and realize automatic switching of the dilution method.

[0039] Afterwards, the pipeline heating device in the embodiment of the present application includes a heating belt 15 and a temperature controller, which can be used to heat all the organic amine gas passing through the pipeline at about 50° C. (ie, the target temperature) to reduce the pipeline loss of the organic amine and accelerate the adsorption equilibrium of the organic amine pipeline.

[0040] In addition, there are four gas flow control generators in the embodiment of the present application, which can be used to generate the first type of organic amine gas, the second type of organic amine gas and the third type of organic amine gas with target flow rates.

[0041] The calibration module 104 is used to generate zero gas or nitrogen dilution gas, and dilute the first type of organic amine gas and / or the second type of organic amine gas and / or the third type of organic amine gas by the zero gas or the nitrogen dilution gas to generate an organic amine standard gas of a target concentration, and use the organic amine standard gas of the target concentration to calibrate the target back-end instrument to be calibrated.

[0042] The calibration module 104 in the embodiment of the present application can generate two paths of zero gas or nitrogen dilution gas with a certain flow rate to dilute the high-concentration organic amine gas; and one path of the dilution gas generated by the calibration module 104 is connected to the first organic amine gas generating unit 101 and the second organic amine gas generating unit 102 through a pipeline after being combined, and the other path of the dilution gas is connected to the rear end of the third organic amine gas generating unit 103.

[0043] Optionally, in one embodiment of the present application, the calibration module 104 includes: a zero gas or nitrogen generator, which is used to generate zero gas or nitrogen dilution gas through a gas flow control generator.

[0044] It should be noted that the calibration module 104 in the embodiment of the present application also includes two gas flow control generators (i.e., a third gas flow control generator 10 and a fourth gas flow control generator 11) and a zero gas or nitrogen generator 9, which can generate a certain flow of zero gas or nitrogen dilution gas through the gas flow control generator.

[0045] Optionally, in one embodiment of the present application, the first organic amine gas generating unit 101 includes: a pressure reducing valve and a gas generator 1 .

[0046] Among them, pressure reducing valve.

[0047] The gas generator 1 is used to generate a first type of organic amine gas that meets the concentration requirement corresponding to the target gas generator 1 through a pressure reducing valve.

[0048] It should be noted that the first organic amine gas generating unit 101 in the embodiment of the present application includes: a pressure reducing valve and a gas generator 1 .

[0049] Specifically, the embodiment of the present application can connect the gas generator 1 and the first gas flow control generator 2 corresponding to the first organic amine gas generating unit 101 in sequence through a pipeline, and in the gas generator calibration mode, the gas generator 1 is controlled by the pressure reducing valve to generate a certain high concentration of organic amine gas, and the first gas flow control generator 2 is used to generate a high concentration of the first type of organic amine gas with a required flow rate. The first type of organic amine gas mainly includes piperazine, 2-amino-2-methyl-1-propanol, N,N-dimethylformamide, etc.

[0050] In the specific implementation process, the embodiment of the present application can control the opening of the gas cylinder passage through the first electric three-way valve 12 and the third electric three-way valve 14. At the same time, the second electric three-way valve 13 controls the flow of zero gas or nitrogen generated by the zero gas or nitrogen generator 9 to quantitatively dilute the organic amine gas in the gas generator 1 under the control of the third gas flow control generator 10. The first gas flow control generator 2 controls the gas outlet flow of the gas generator 1. After dilution, the organic amine gas of a certain concentration enters the back-end instrument 16 to achieve calibration.

[0051] Therefore, the embodiments of the present application can efficiently calibrate various organic amine species (i.e., first type organic amine gas) such as piperazine, 2-amino-2-methyl-1-propanol, N,N-dimethylformamide, etc. through the first organic amine gas generation unit 101 and the calibration module 104.

[0052] Optionally, in one embodiment of the present application, the second organic amine gas generating unit 102 includes: a gas permeation rate control unit (ie, an organic amine permeation tube) and a nitrogen generating unit (ie, a high-purity nitrogen gas bottle).

[0053] Wherein, the gas permeation rate control unit is used to generate organic amine gas with a standard permeation rate at a target water bath temperature.

[0054] The nitrogen generation unit 3 is used to generate nitrogen that meets the preset flow rate and purity requirements.

[0055] Furthermore, if Figure 2 As shown, the second organic amine gas generating unit 102 in the embodiment of the present application includes a gas permeation rate control unit, a nitrogen generating unit 3 and a second gas flow control generator 4.

[0056] In the calibration mode of the gas permeation rate control unit, the first electric three-way valve 12 and the third electric three-way valve 14 control the opening of the permeation tube passage, and at the same time, the second electric three-way valve 13 controls the flow of zero gas or nitrogen generated by the zero gas or nitrogen generator 9 to quantitatively dilute the organic amine gas generated by the permeation under the control of the third gas flow control generator 10.

[0057] In addition, the organic amine permeation device 5 in the embodiment of the present application uses a U-shaped tube to connect the gas path. The U-shaped tube uses glass beads to even out the inlet temperature on the air inlet side, and a gas permeation rate control unit is placed on the air outlet side. The organic amine permeation device 5 has a glass grid in the middle, a compartment to accommodate the permeation tube and another filled with glass beads with a diameter of 0.5 cm for rapid temperature exchange. In the embodiment of the present application, the U-shaped glass tube can be immersed in an 80°C constant temperature water bath to ensure that the temperature is constant, at the standard operating temperature of the permeation tube and the permeation rate is stable. The nitrogen generation unit 3 generates 150-180sccm of high-purity nitrogen carrier gas under the control of the second gas flow control generator 4, carrying the organic amine generated by the permeation, and is diluted by the dilution gas into the rear-end calibration instrument 16.

[0058] Therefore, the embodiments of the present application can achieve the calibration of various organic amine species (ie, second type organic amine gas) including monoethanolamine, diethanolamine, triethanolamine, methyldiethanolamine, etc.

[0059] Optionally, in one embodiment of the present application, the third organic amine gas generating unit 103 includes: a transmission unit (ie, a liquid flow controller) 7, an organic amine reagent bottle 6 and a liquid calibration unit.

[0060] The transmission unit 7 is used to transport the third type of organic amine gas with a target flow rate to the preset liquid calibration unit 8 .

[0061] The organic amine reagent bottle 6 is used to transfer at least one preset organic amine reagent to the liquid calibration unit 8 through the transmission unit 7 .

[0062] The liquid calibration unit 8 is used to generate an organic amine standard gas corresponding to the third type of organic amine gas based on at least one organic amine reagent and the third type of organic amine gas, so as to calibrate the target back-end instrument 16 to be calibrated with multiple types of organic amine gases through the organic amine standard gas.

[0063] The third organic amine gas generating unit 103 in the embodiment of the present application includes: a transmission unit 7 , an organic amine reagent bottle 6 and a liquid calibration unit 8 .

[0064] It should be noted that, in the embodiment of the present application, the third organic amine gas generating unit 103 is connected to the first organic amine gas generating unit 101 through the third electric three-way valve 14. The organic amine reagent bottle 6, the transmission unit 7, and the liquid calibration unit 8 are sequentially connected through the pipeline and connected to one end inlet of the first electric three-way valve 12 through the pipeline.

[0065] The zero gas or nitrogen generator 9 is connected to the third gas flow control generator 10 and the fourth gas flow control generator 11 through pipelines and the second electric three-way valve 13 respectively. One pipeline of the third gas flow control generator 10 is connected to the third organic amine gas generating unit 103 and the first organic amine gas generating unit 101 at the rear end and merged into one pipeline and connected to the other end inlet of the first electric three-way valve 12. One pipeline of the fourth gas flow control generator 11 is connected to the liquid calibration unit 8 through a pipeline to play a dilution role. The outlet of the third electric three-way valve 14 can be connected to the calibrated analytical instrument (i.e., the rear-end instrument 16) through a pipeline.

[0066] In the calibration mode of the liquid calibration unit, the first electric three-way valve 12 controls the passage of the liquid calibration unit 8 to open, and at the same time, the second electric three-way valve 13 controls the flow of zero gas or nitrogen generated by the zero gas or nitrogen generator 9 to dilute the organic amine generated by the liquid calibration unit 8 under the control of the fourth gas flow control generator 11 to generate organic amine gas of target concentration.

[0067] In the actual implementation process, the embodiment of the present application can allow the purchased commercial organic amine reagent 6 to enter the liquid calibration unit 8 together with the dilution gas through the transmission unit 7, so that the organic amine standard gas of the required concentration is generated under the action of the liquid calibration unit 8, and enters the back-end instrument 16 through the first electric three-way valve 12 to realize the calibration of the back-end instrument 16.

[0068] Therefore, the embodiment of the present application can calibrate most organic amine solvents available on the market through the third organic amine gas generating unit 103 .

[0069] It should be noted that, considering that organic amines have high viscosity and are easily attached to pipelines and cause losses, the pipelines through which the organic amines pass in the embodiments of the present application are wrapped with heating tapes 15 (i.e., pipeline heating devices) and heated to about 50° C. to reduce pipeline losses and accelerate the pipeline balance of the organic amines.

[0070] It can be understood that the embodiment of the present application provides organic amine gas of known concentration by coupling various organic amine production methods such as the gas generator 1, the permeation tube, and the liquid generating unit with the gas flow control generator, thereby being able to accurately correct the device to be calibrated and achieve the production and efficient calibration of multiple species of organic amines.

[0071] According to the multiple types of organic amine gas calibration device proposed in the embodiment of the present application, it includes a first organic amine gas generation unit 101, which is used to generate a first type of organic amine gas that meets the concentration requirements corresponding to the target gas generator; a second organic amine gas generation unit 102, which is used to generate a second type of organic amine gas that meets the concentration requirements corresponding to the target gas permeation rate control unit; a third organic amine gas generation unit 103, which is used to generate a third type of organic amine gas that meets the concentration requirements corresponding to the target organic amine liquid; a calibration module 104, which is used to generate zero gas or nitrogen dilution gas, and dilute the first type of organic amine gas and / or the second type of organic amine gas and / or the third type of organic amine gas by zero gas or nitrogen dilution gas to generate an organic amine standard gas of a target concentration, and use the organic amine standard gas of the target concentration to calibrate the target back-end instrument to be calibrated. The present application can achieve the generation and efficient calibration of multiple species of organic amines by coupling the calibration mode of gas cylinders, permeation tubes and liquid calibration units, thereby avoiding the synchronization system calculation delay error caused by the waiting time of the DTMB-A modulator in processing the TS stream, and meeting the requirements of the DTMB-A system single frequency network.

[0072] Next, a method for calibrating various types of organic amine gases according to an embodiment of the present application is described with reference to the accompanying drawings.

[0073] Figure 3 A flow chart of a method for calibrating multiple types of organic amine gases provided in an embodiment of the present application.

[0074] like Figure 3 As shown, the method for calibrating various types of organic amine gases includes the following steps:

[0075] In step S301, a first type organic amine gas, a second type organic amine gas and a third type organic amine gas are generated respectively to meet the concentration requirements of the target gas generator, the target gas permeation rate control unit and the target organic amine liquid.

[0076] In step S302, zero gas or nitrogen dilution gas is generated, and one or more organic amine gases of the first type organic amine gas, the second type organic amine gas and the third type organic amine gas are diluted by the zero gas or the nitrogen dilution gas to generate an organic amine standard gas of a target concentration, and the target back-end instrument to be calibrated is calibrated using the organic amine standard gas of the target concentration.

[0077] It should be noted that the above explanation of the embodiment of the device for calibrating various types of organic amine gases is also applicable to the method for calibrating various types of organic amine gases of this embodiment, and will not be repeated here.

[0078] According to the method for calibrating multiple types of organic amine gases proposed in the embodiment of the present application, a first type of organic amine gas, a second type of organic amine gas, and a third type of organic amine gas are generated respectively to meet the concentration requirements of the target gas generator, the target gas permeation rate control unit, and the target organic amine liquid; zero gas or nitrogen dilution gas is generated, and one or more organic amine gases of the first type of organic amine gas, the second type of organic amine gas, and the third type of organic amine gas are diluted by the zero gas or nitrogen dilution gas to generate an organic amine standard gas of a target concentration, and the target back-end instrument to be calibrated is calibrated using the organic amine standard gas of the target concentration. The present application can realize the generation and efficient calibration of multiple species of organic amines by coupling the calibration modes of gas cylinders, permeation tubes, and liquid calibration units, thereby avoiding the calculation delay error of the synchronization system caused by the waiting time of the DTMB-A modulator in processing the TS stream, and meeting the requirements of the single-frequency network of the DTMB-A system.
