Specifically, the first gas can be an inert gas, preferably nitrogen, which is cheap and easy to obtain; and the second gas is carbon dioxide, which is used to supply the carbonization chamber 02 for carbonization oxidation.

[0037] The gas detection chamber 4 is connected to the carbonization chamber 02. The gas detection chamber 4 can be used to measure the gas concentration in the carbonization chamber 02. Specifically, after the carbonization chamber 02 uses the mixed gas to perform the carbonization operation, or when the mixed gas in the carbonization chamber 02 flows back to the gas mixing chamber 1 through the gas detection chamber 4, the amount and concentration of the remaining gas in the carbonization chamber 02 can be measured by the gas detection chamber 4, and compared with the first gas detector 111 at the output end, the mixed gas consumption of the carbonization chamber 02 can be calculated, so that the entire carbonization process of the carbonization chamber 02 is quantified, the control accuracy of the carbonization process is improved, and the continuous operation of the carbonization process is facilitated.

The combination of the two can ensure that the concentration of the supplied gas remains unchanged while continuously supplying gas to the carbonization chamber 02 through the gas mixing chamber 1; it can also judge whether there is an abnormality in the valve through the numerical difference between the first gas detector 111 and the second concentration detector 15, thereby preventing the quantitative carbonization box 01 from being damaged.

[0043] The exhaust valve 12 is used to directly exhaust the gas in the gas mixing chamber 1.

The electrical output module 5 is used to transmit data, and the electrical output module 5 is connected to the control mainboard 2, and can also be connected to an external device to exchange data, so that the control mainboard 2 can be directly controlled by the external device, and then the opening and closing, opening degree, etc. of each instrument, pump, and valve in the quantitative carbonization box 01 can be controlled.

[0048] In some embodiments, the quantitative carbonization box 01 further includes a shell 7, which is a hollow cavity structure, and the gas mixing chamber 1, the gas detection chamber 4, and the control main board 2 are all arranged inside the cavity of the shell 7; the shell 7 is provided with a display screen 3, a data interface 9, and a switch 10; the display screen 3, the data interface 9, and the switch 10 are all electrically connected to the control main board 2.

Specifically, the diameter of the cylindrical area can be 32mm and the height can be 200mm.

[0050] Furthermore, a flow meter 8 is also provided on the housing 7. Specifically, the flow meter 8 is connected to the output end of the gas mixing chamber 1, and measures the concentration, content and flow rate of the output mixed gas together with the first gas detector 111, and supplies a quantitative mixed gas to the carbonization chamber 02. At the same time, the flow meter 8 is also connected to the control main board 2, and the flow meter 8 can be adjusted to adjust the flow rate of the mixed gas supplied from the output end to the carbonization chamber 02.

[0051] Combined with reference Figure 4 In the second embodiment of the present application, a gas concentration adjustment method is provided, wherein the quantitative carbonization box 01 described in any one of the first embodiment and its implementation modes is used to adjust the gas in the carbonization chamber 02, and the gas concentration adjustment method includes the following steps:

[0052] S1: Input the set target unit second gas content concentration;

[0053] S2: starting the first air intake valve 13 and the second air intake valve 14 to provide the first gas and the second gas to the gas mixing chamber 1, and mixing them to obtain a mixed gas;

[0054] S3: Determine whether the concentration of the second gas in the mixed gas is equal to the set target unit concentration of the second gas. If yes, input the mixed gas into the carbonization chamber 02; if no, adjust the opening of the first air intake valve 13 and the second air intake valve 14 until the concentration of the second gas in the mixed gas is equal to the set target unit concentration of the second gas;

[0055] S4: Pass the gas in the carbonization chamber 02 into the gas detection chamber 4, and determine whether the gas in the gas detection chamber 4 is equal to the set target unit second gas content concentration. If so, the gas mixing chamber 1 stops inputting the mixed gas into the carbonization chamber 02, and the gas in the carbonization chamber 02 circulates in the carbonization chamber 02 and the gas detection chamber 4; if not, the gas mixing chamber 1 continues to input the mixed gas into the carbonization chamber 02 until the gas in the gas detection chamber 4 is equal to the set target unit second gas content concentration.

[0056] Step S1 is to input the set target unit second gas content concentration (i.e., set concentration) on the control main board 2. The set concentration can be a specific concentration range, i.e., the concentration can fluctuate within a certain range. Specifically, the set concentration can be 475ppm±25ppm, i.e., within the range of 450 to 500ppm.

[0057] Step S2 is the initial stage, in which the opening and closing of the first air intake valve 13 and the second air intake valve 14 and the opening degree are controlled by the control main board 2, so as to adjust the air intake amount of the first gas and the second gas, and the first gas and the second gas introduced are directly mixed in the gas mixing chamber 1 to obtain a mixed gas; specifically, at this time, the gas delivery valve 112 and the gas outlet valve 12 at the output end are in a closed state.

[0058] In step S3, the control main board 2 adjusts the opening of the first air inlet valve 13 and the second air inlet valve 14 according to the set target unit second gas content concentration and the concentration of the mixed gas in the second concentration detector 15, until the second gas concentration in the mixed gas reaches the set value. The process of adjusting the concentration of the mixed gas is the gas distribution process. During this process, the valve will be opened and closed according to the situation to ensure the smooth progress of the gas distribution process, wherein the gas introduced can be discharged through the gas outlet valve port; preferably, the gas delivery valve 112 and the gas outlet valve 12 at the output end are in a closed state during this process to reduce the complexity of the gas distribution process.

[0059] Furthermore, in step S3, when the concentration of the second gas content in the mixed gas is higher than the set target unit second gas content concentration, the opening of the first intake valve 13 is adjusted to be greater than the opening of the second intake valve 14, or the second intake valve 14 is closed; when the concentration of the second gas content in the mixed gas is lower than the set target unit second gas content concentration, the opening of the first intake valve 13 is adjusted to be less than the opening of the second intake valve 14, or the first intake valve 13 is closed.

[0060] During the gas distribution process, the amount of the first gas and the second gas to be added can be calculated according to the following formula, that is, n=ρV / m; specifically, this is the calculation formula for the first gas and the second gas at room temperature and standard atmospheric pressure, and n, ρ, and m are the molar amount, density, and mass of the required gas, respectively.

[0061] In addition, the second gas is carbon dioxide, which is the target gas, so the amount of carbon dioxide can be calculated according to the formula, and then the volume and amount of the first gas can be calculated according to its required concentration.

[0062] Step S4, passing the gas in the carbonization chamber 02 into the gas detection chamber 4, and determining whether the gas in the gas detection chamber 4 is equal to the set target unit second gas content concentration. If so, the gas mixing chamber 1 stops inputting the mixed gas into the carbonization chamber 02, and the gas in the carbonization chamber 02 circulates in the carbonization chamber 02 and the gas detection chamber 4; if not, the gas mixing chamber 1 continues to input the mixed gas into the carbonization chamber 02 until the gas in the gas detection chamber 4 is equal to the set target unit second gas content concentration.

[0063] When the gas distribution process is completed and the mixed gas of the set concentration is obtained in the gas mixing chamber 1, the mixed gas can be input into the carbonization chamber 02 through the first pressure pump 11 to control the input gas flow rate; the amount of mixed gas introduced can be recorded in real time according to the first gas detector 111, transmitted to the control main board 2 for storage and update, and can also be displayed on the display screen 3. At the same time, when the mixed gas in the carbonization chamber 02 flows back to the gas detection chamber 4, the concentration can be detected by the first concentration detector 41, and the data can be transmitted to the control main board 2 for storage, which can be used to determine whether to end the mixed gas charging process for the carbonization chamber 02, and quantitatively calculate the consumption of the mixed gas and the consumption of the second gas.

[0064] Specifically, when the gas in the gas detection chamber 4 is equal to the set target unit second gas content concentration, the gas supply valve 112 is closed to allow the gas in the carbonization chamber 02 to circulate in the carbonization chamber 02 and the gas detection chamber 4, thereby performing carbonization maintenance on the items in the carbonization chamber 02, and performing low-field nuclear magnetic resonance continuous testing through the first concentration detector 41 of the gas detection chamber 4; when the gas in the carbonization chamber 02 is too little or the concentration is too low, it is detected by the gas detection chamber 4, and then the gas supply valve 112 is opened by controlling the main board 2 to perform the gas replenishment operation in the carbonization chamber 02; before replenishing the gas, the opening of the first air inlet valve 13 and the second air inlet valve 14 can be adjusted to adjust the gas concentration in the gas mixing chamber 1, and then the gas of a specific concentration is input into the carbonization chamber 02 for replenishment.

[0065] Combined with reference Figure 5 , errors may occur in the gas concentration adjustment method; 1, 2, 3, and 4 in the figure only represent normal fluctuations in gas concentration within the set concentration range.

[0066] Among them, error α refers to the gas distribution stage of the gas mixing chamber 1, that is, in step 3, the concentration of the second gas is still continuously filled after exceeding the set concentration, so that the concentration of the second gas continues to increase; Countermeasure α: At this time, it is necessary to close the second air inlet valve 14 and the gas delivery valve 112, open the first air inlet valve 13, and fill the first gas to reduce the concentration of the second gas until it reaches the set concentration; during this process, the air outlet valve 12 is always in the default closed state.

[0067] Error β refers to the abnormal opening and closing of the first air inlet valve 13 and the second air inlet valve 14 when the gas supply valve 112 is closed, that is, within 10 seconds after the concentration of the mixed gas measured by the second concentration detector 15 in the gas mixing chamber 1 is the same as the set concentration for the first time, the concentration stays at the set concentration for less than 5 seconds, then it is judged that there is an abnormality and cannot be stabilized; Countermeasure β: At this time, the gas supply valve 112, the first air inlet valve 13 and the second air inlet valve 14 are directly closed by controlling the main board 2, and the air outlet valve 12 is opened to discharge all the gas in the gas mixing chamber 1 until it is exhausted, and the first air inlet valve 13 and the second air inlet valve 14 are reopened to input gas into the gas carbonization chamber 02, that is, the initial stage of operation is restarted.

[0068] The gas concentration adjustment method of this embodiment can be combined with the quantitative carbonization box 01 to complete the gas distribution process of the gas mixing chamber 1, the inflation operation to the carbonization chamber 02 through the gas mixing chamber 1 and the subsequent gas replenishment process, and provides a method for dealing with errors and abnormalities, so that the objects in the carbonization chamber 02 can be carbonized and maintained by quantitative carbon dioxide. At the same time, low-field nuclear magnetic resonance continuous testing can be performed through the gas detection chamber 4 to ensure the stable operation of the carbonization chamber 02.

[0069] The third embodiment of the present application provides a quantitative carbonization system, including a quantitative carbonization box 01 and a carbonization chamber 02; the quantitative carbonization box 01 is the quantitative carbonization box 01 described in any one of the first embodiment and its implementation modes; the output end of the gas mixing chamber 1 is connected to the carbonization chamber 02; the gas detection chamber 4 is connected to the carbonization chamber 02.
