Description

Technical Field

[0001] The present invention relates to the technical field of radioactive waste gas treatment, and in particular to a method and device for treating multi-form 14 14C in radioactive hydrogen-containing waste gas. Background Art

[0002] The International Atomic Energy Agency has pointed out that carbon-14 ( 14 14C) in radioactive gaseous effluents has become the radionuclide that contributes the most to the effective dose of the surrounding public during the normal operation of nuclear power plants. Most of the operating and under-construction nuclear power units in China are pressurized water reactors. The carbon-14 in pressurized water reactors is mainly discharged through the hydrogen-containing subsystem of the waste gas treatment system and mainly exists in the form of hydrocarbons. Since it is difficult to efficiently capture hydrocarbons by adsorption and filtration means, the currently commonly used technical route is to oxidize and convert carbon-14 hydrocarbons into carbon-14 carbon dioxide with more active physical and chemical properties for subsequent treatment.

[0003] However, since the hydrogen concentration in the hydrogen-containing subsystem of the waste gas treatment system is generally within the explosion limit range, and the hydrogen volume fraction in the subsystems of some third-generation nuclear power units exceeds 60%, a hydrogen explosion may easily occur during the oxidation of hydrocarbons. At the same time, when treating 14 14C, the existing technology uses the adsorption method with an adsorption material, and the adsorption dosage calculation is not based on the actual gas content, resulting in a relatively high dosage of the adsorption material and a high cost.

[0004] The above problems need to be solved urgently. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in combination with specific embodiments and corresponding drawings of the present invention. In the description of the present invention, it should be noted that the term "or" is generally used in the sense of including "and / or" unless otherwise clearly specified in the context.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a magnetic connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, or more, unless otherwise clearly and specifically limited.

[0028] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] First, for the convenience of understanding the embodiments of the present invention, some terms or nouns involved in the present invention will be explained below:

[0030] Polymorphism 14 C, that is, carbon-14, is a radioactive isotope of carbon. There are 6 protons and 8 neutrons in the atomic nucleus of carbon-14, and the atomic weight is about 14. Carbon-14 is radioactive and will undergo β - decay. During the decay process, a neutron in the carbon-14 atomic nucleus will be transformed into a proton, while emitting an electron and an antineutrino, thus becoming nitrogen-14.

[0031] The gas separation membrane is a selective membrane that can exhibit different permeabilities and selectivities for different types of gas molecules. Therefore, a certain special gas can be effectively separated from the gas mixture. The working principle of the gas separation membrane is based on factors such as the size, shape, polarity, and chemical interaction of gas molecules. These characteristics determine the speed at which each gas molecule passes through the membrane.

[0032] To solve the problems existing in the prior art, the embodiments of the present application provide a method and device for treating polymorphic 14 C in radioactive hydrogen-containing waste gas.

[0033] Embodiment 1

[0034] This embodiment provides a method for treating polymorphic 14 C in radioactive hydrogen-containing waste gas. As Figure 1 shown, Figure 1 is a flowchart of a method for treating polymorphic 14 C in radioactive hydrogen-containing waste gas in Embodiment 1 of the present invention. The method includes:

[0035] Step S102, obtaining radioactive hydrogen-containing waste gas;

[0036] Optionally, 14 C (carbon-14) in the radioactive hydrogen-containing waste gas has become the nuclide that contributes the most to the effective dose of the surrounding public during the normal operation of nuclear power plants. Among them, 14 C is radioactive. It is necessary to collect the above-mentioned radioactive hydrogen-containing waste gas and treat it to reduce the impact of radioactive elements on the surrounding environment.

[0037] Step S104, performing hydrogen separation on the radioactive hydrogen-containing waste gas to obtain hydrogen-separated waste gas;

[0038] In some preferred embodiments, before separating hydrogen from the radioactive hydrogen-containing waste gas to obtain the hydrogen-separated waste gas, the method further includes: inputting the radioactive hydrogen-containing waste gas into an electrostatic precipitator filter to filter out aerosol particles in the radioactive hydrogen-containing waste gas to obtain a first waste gas; inputting the first waste gas into a dehumidifying material to filter out moisture in the first waste gas to obtain a second waste gas.

[0039] Optionally, to prevent the clogging of the gas separation membrane used in the subsequent hydrogen separation due to the aerosol particles and moisture carried in the radioactive hydrogen-containing waste gas during the front-end treatment process of the radioactive hydrogen-containing waste gas, which may affect the hydrogen separation process, it is first necessary to perform dehumidification and dust removal on the radioactive hydrogen-containing waste gas.

[0040] Optionally, an efficient filter or electrostatic precipitation technology (i.e., an electrostatic precipitator filter) can be used to remove aerosol particles in the radioactive hydrogen-containing waste gas to obtain a first waste gas. A dehumidifying material is used for dehumidification to obtain a second waste gas. Among them, the dehumidifying material uses a porous adsorption material, that is, the adsorption of moisture is realized, and the porous adsorption material can be selected from silica gel, activated carbon, molecular sieve or metal-organic framework material.

[0041] In some preferred embodiments, when the radioactive hydrogen-containing waste gas includes radioactive iodine, krypton, xenon, and 14 hydrocarbons in the form of

[0042] C, before separating hydrogen from the radioactive hydrogen-containing waste gas to obtain the hydrogen-separated waste gas, the method further includes: inputting the second waste gas into an iodine adsorber to filter out radioactive iodine in the radioactive hydrogen-containing waste gas to obtain a third waste gas; inputting the third waste gas into a retention bed to filter out krypton and xenon in the third waste gas to obtain a fourth waste gas. 14 Since there is not only hydrogen and 14 C in various forms in the radioactive hydrogen-containing waste gas, but also radioactive iodine, krypton, and xenon, to avoid the influence of radioactive iodine, krypton, and xenon on the treatment of 14 C in various forms, it is necessary to remove radioactive iodine, krypton, and xenon before treating

[0043] Optionally, after removing the aerosol particles and moisture, at this time, the radioactive hydrogen-containing waste gas mainly includes nitrogen, hydrogen, radioactive iodine, krypton, xenon, and hydrocarbons ( 14CH4). The iodine adsorber is used to adsorb radioactive iodine, and the retention bed is used to purify most of krypton (Kr) and xenon (Xe). Specifically, the iodine adsorber consists of a stainless-steel shell, an activated carbon adsorbent layer, and a sealing material. In the square stainless-steel shell, equidistant V-shaped and semi-V-shaped sieve plates are arranged. The space between the two wings of each sieve plate serves as an air flow channel, and the activated carbon layer is filled between adjacent sieve plates, making the carbon layer inside the iodine adsorber distributed in a folded manner. When the radioactive gas passes through the carbon layer, gaseous iodine, radon daughters, and radioactive aerosols can be effectively removed by the activated carbon. Specifically, the retention bed is filled with activated carbon. Through the activated carbon adsorption layer inside it, when the third exhaust gas containing krypton and xenon elements passes through, krypton and xenon in the third exhaust gas are removed. Due to its porous structure, activated carbon has a strong adsorption capacity and can adsorb various gases including krypton and xenon. In the retention bed, when the gas passes through the activated carbon layer, radioactive inert gases such as krypton and xenon are adsorbed on the surface of the activated carbon, thereby achieving the purpose of removal.

[0044] It should be noted that during the removal process of the above aerosol particles, moisture, radioactive iodine, krypton, and xenon, complete removal cannot be achieved. When within the standard content range, it is considered that the removal is completed.

[0045] In some preferred embodiments, hydrogen is separated from the radioactive hydrogen-containing exhaust gas to obtain hydrogen-separated exhaust gas, including: performing pressurization treatment on the radioactive hydrogen-containing exhaust gas to obtain a first pressurized gas, wherein the pressure of the pressurization treatment is greater than a first preset pressure value; introducing the first pressurized gas into a gas separation membrane to obtain a hydrogen-separated gas, wherein the gas separation membrane includes a permeate side and a non-permeate side, hydrogen enters the permeate side, and the hydrogen-separated gas remains on the non-permeate side, and a second preset proportion of nitrogen is introduced into the permeate side of the gas separation membrane.

[0046] Optionally, during the process of treating hydrogen, the main components of the discharged gas are nitrogen and hydrogen (after passing through the gas separation membrane, hydrogen is discharged and the remaining gases are left), the discharged gas is not radioactive, and the remaining radioactive substances mainly include 14 hydrocarbons of 14 C, among which 14 the main form of hydrocarbons of 14 C is

[0047] Specifically, considering that the kinetic radius of hydrogen (2.89 angstroms ) is much smaller than that of nitrogen (kinetic radius of ), Xe (kinetic radius of ), and Kr (kinetic radius of ) kinetic radius and 14 CH4 (with a kinetic radius of ), so the method of using a gas separation membrane can be selected to adjust the radius of the gas separation membrane to only allow hydrogen molecules to pass through, thereby achieving the filtration of hydrogen.

[0048] Optionally, to ensure that the fourth exhaust gas can be quickly filtered (i.e., hydrogen can be separated), the fourth exhaust gas needs to be pressurized to a first preset pressure value, where the first preset pressure value is greater than or equal to 1 mpa. At this time, the pressurized fourth exhaust gas moves rapidly towards the gas separation membrane, thereby achieving the effect of separating hydrogen.

[0049] It should be noted that since the fourth exhaust gas contains a large amount of hydrogen, there is an explosion risk during the compression process of the fourth exhaust gas, and an explosion-proof compressor should be used.

[0050] Optionally, when the fourth exhaust gas passes through the gas separation membrane and hydrogen is separated through the permeation side of the gas separation membrane, to prevent the hydrogen purity on the permeation side from being too high after filtration and easily causing an explosion, it needs to be mixed with nitrogen in a certain ratio (the second preset ratio) and then discharged. That is, by introducing nitrogen into hydrogen, the concentration of hydrogen is diluted to less than 2%, and then the removal of hydrogen is achieved through a hydrogen-oxygen composite catalytic reaction.

[0051] Optionally, the nitrogen mixing amount should be calculated according to diluting hydrogen to below the explosion limit concentration, and real-time online hydrogen monitoring equipment should be equipped. The remaining hydrogen-separated exhaust gas is discharged through the non-permeation side for subsequent treatment.

[0052] Step S106, introducing air in a first preset ratio into the hydrogen-separated exhaust gas for oxidation treatment to obtain oxidized exhaust gas, where the 14 C is in the form of carbon dioxide;

[0053] In some preferred embodiments, before introducing air in a first preset ratio into the hydrogen-separated exhaust gas for oxidation treatment to obtain oxidized exhaust gas, the method further includes: detecting the hydrogen concentration in the hydrogen-separated exhaust gas; when the hydrogen concentration is greater than or equal to the preset concentration, pressurizing the hydrogen-separated exhaust gas again and introducing it into the gas separation membrane for hydrogen separation to obtain hydrogen-separated exhaust gas, and detecting the hydrogen concentration in the hydrogen-separated exhaust gas until the hydrogen concentration in the hydrogen-separated exhaust gas is less than the preset concentration.

[0054] Optionally, real-time online hydrogen monitoring equipment is equipped to ensure that the hydrogen concentration is below 1% during the treatment process. At this time, a relatively safe oxidation environment is achieved. The hydrogen-separated exhaust gas after separating hydrogen is mixed with air in a first preset ratio, and most of the 14 CH4 is oxidized to 14 CO2, and itself is in the form of 14in the presence of CO2 14 C will not participate in the reaction further. Therefore, after the reaction, 14 C mainly exists in the form of 14 CO2. Specifically, 14 The oxidation methods of CH4 include thermal catalytic oxidation, photocatalytic oxidation or plasma catalytic oxidation. Among them, thermal catalytic oxidation is a process of accelerating the oxidation reaction through a catalyst, which 14 oxidizes and decomposes CH4 into carbon dioxide and water at a relatively high temperature (usually 250 - 500 °C). This process requires heating the hydrogen separation waste gas to a certain temperature to activate the catalyst, thereby promoting the progress of the oxidation reaction. The role of the catalyst is to lower the activation energy of the reaction and increase the reaction rate, enabling the oxidation reaction to proceed efficiently at a lower temperature.

[0055] In some preferred embodiments, introducing air in a first preset ratio into the hydrogen separation waste gas for oxidation treatment to obtain oxidized waste gas, including: introducing air in a first preset ratio into the hydrogen separation waste gas for oxidation treatment to obtain water-containing waste gas, wherein water molecules are generated during the oxidation treatment; inputting the water-containing waste gas into a dehumidifying material to filter out the moisture in the water-containing waste gas,

[0056] to obtain oxidized waste gas, wherein the 14 C in the oxidized waste gas is in the form of carbon dioxide.

[0057] Optionally, since 14 water is generated during the oxidation process of CH4, that is, 14 CH4 reacts with oxygen in the air to produce 14 CO2 and water. To avoid the water molecules clogging the pores of the permeation during the subsequent permeation treatment of 14 CO2, it is necessary to remove the water therein, that is, dehumidification treatment. A porous adsorption dehumidifying material can be used for dehumidification, and the porous adsorption material can be silica gel, activated carbon, molecular sieve or metal-organic framework material. After the complete oxidation reaction by introducing air into the hydrogen separation waste gas, dehumidification treatment is carried out, and finally oxidized waste gas containing 14 CO2 is obtained.

[0058] Step S108, separating the oxidized waste gas based on the permeation effect to obtain a preliminarily separated waste gas;

[0059] In some preferred embodiments, separating the oxidized waste gas based on the permeation effect to obtain a preliminarily separated waste gas, including: performing pressurization treatment on the oxidized waste gas to obtain a second pressurized gas, wherein the pressure of the pressurization treatment is greater than a second preset pressure value; introducing the second pressurized gas into a gas separation membrane to adjust the solution-diffusion coefficient of the gas separation membrane to obtain a preliminarily separated waste gas, wherein the gas separation membrane includes a permeation side and a non-permeation side, and contains 14 in the form of carbon dioxideThe initially separated gas of C enters the permeate side, and the gas on the non-permeate side is discharged through the waste gas emission system.

[0060] Optionally, since pressurization is performed before hydrogen removal, after the subsequent reaction process, the oxidized waste gas is still under pressure, that is, the hydrogen separation waste gas and air still maintain a certain pressure after mixing. At this time, pressure detection can be carried out. If the pressure is relatively high, pressurization may not be required anymore. If the pressure is lower than the second preset pressure value, pressurization treatment is needed. Among them, the second preset pressure value is greater than or equal to 1 mpa. It should be noted that the second preset pressure value can be different from the first preset pressure value. The pressurized oxidized waste gas passes through the gas separation membrane, and 14 selective separation is carried out by using the difference in the dissolution and diffusion coefficients of CO2 and the remaining gases in the oxidized waste gas in the organic polymer membrane (gas separation membrane). 14 CO2 is separated through the permeate side of the gas separation membrane and temporarily stored in the gas storage tank. If there are no radioactive substances in the remaining waste gas, it is discharged through the non-permeate side and can be normally discharged through the waste gas emission system.

[0061] It should be noted that according to the content recorded in the "Classification of Radioactive Wastes of the Ministry of Ecology and Environment of the People's Republic of China", the 14 activity concentration level of C in the low-radioactivity waste gas cannot exceed 1×108 Bq / kg, otherwise it needs to be disposed of as medium-radioactivity waste gas, and the disposal cost and difficulty will increase significantly.

[0062] Step S110, based on the initially separated waste gas, detect the 14 activity concentration of C in the form of carbon dioxide in the initially separated waste gas;

[0063] In some preferred embodiments, based on the initially separated waste gas, detecting the 14 activity concentration of C in the form of carbon dioxide in the initially separated waste gas includes: irradiating the initially separated waste gas with laser light to determine the 14 absorption degree of C in the form of carbon dioxide to the laser light with a preset wavelength; based on the absorption degree, determine the 14 activity concentration of C in the form of carbon dioxide in the initially separated waste gas.

[0064] Optionally, to detect the 14 activity concentration of C in the gas storage tank (i.e., the permeate side of the gas separation membrane), the laser irradiation method, the liquid scintillation method or the accelerator mass spectrometry method can be used. Specifically, the laser irradiation method is to irradiate the initially separated waste gas with laser light. After irradiation, the 14 absorption degree of C in the form of carbon dioxide to the laser light with a preset wavelength is obtained through a spectrometer, so as to determine the 14 activity concentration of C in the form of carbon dioxide.

[0065] The liquid scintillation method measures the radioactivity in a sample based on the property that molecules such as phosphors or scintillators emit energy in the form of light after absorbing radioactive particles. In the liquid scintillation method, the scintillator is a liquid composed of an organic scintillator dissolved in a suitable solvent. The radioactive substance is dissolved or dispersed and suspended in the scintillation liquid, or is combined with a solid support and then immersed in the scintillation liquid, coming into close contact with the scintillator. When the radioactive substance decays, the emitted rays interact with the scintillator molecules, exciting the scintillator molecules to emit photons. These photons are then received by photoelectric devices such as photomultiplier tubes and converted into electrical signals, thereby achieving the measurement of radioactivity.

[0066] Accelerator mass spectrometry ionizes 14 C gas in the form of carbon dioxide in the ion source of the accelerator, then extracts and accelerates the ion beam to a certain speed, and then enters the mass spectrometry analysis unit. In the mass spectrometry analysis unit, by selecting the charge state, mass-to-charge ratio, energy, and atomic number, the accelerated ions are identified and recorded, achieving the determination of the 14 C ratio.

[0067] Step S112, based on the activity concentration, adsorb 14 C in the form of carbon dioxide to obtain 14 C-containing solidified waste.

[0068] In some preferred embodiments, based on the activity concentration, adsorb 14 C in the form of carbon dioxide to obtain 14 C-containing solidified waste, including: based on the activity concentration, determining the amounts of various adsorption materials required for 14 C in the form of carbon dioxide, where the adsorption material is used to absorb 14 C in the form of carbon dioxide; based on the amounts of various adsorption materials, determining the required adsorption materials; based on the adsorption materials, capturing and fixing 14 C in the form of carbon dioxide to obtain 14 C-containing solidified waste.

[0069] Optionally, according to the measured activity concentration data and the planned exhaust gas volume, calculate 14 the amount of adsorption material for 14 C in the form of carbon dioxide required for the 14 C activity concentration level not to exceed 1×108 Bq / kg. It should be noted that to ensure a relatively high degree of adsorption, the calculation should be carried out according to the 14 C activity concentration level in the form of carbon dioxide being less than 0.7×108 Bq / kg, leaving sufficient activity control margin to avoid the adsorption material being unable to fully adsorb and causing the discharged gas to form medium-level radioactive waste gas.

[0070] Optionally, there are various different adsorption materials available for the adsorption of carbon dioxide. By calculating the dosages of various different adsorption materials and balancing the adsorption effect and the actual dosage, the required adsorption material can be determined based on the material cost and the dosage of the adsorption material, effectively saving the production cost. Specifically, when the material volume of adsorption material A is 10 cubic centimeters and the material volume of adsorption material B is 50 cubic centimeters, and the material cost of adsorption material A is lower, adsorption material A is selected as the subsequent adsorption material, and 10 cubic centimeters is determined as the dosage of the adsorption material.

[0071] Optionally, after determining the adsorption material and the dosage of the adsorption material, the carbon dioxide gas in the gas storage tank is discharged in a controlled manner at a certain flow rate and adsorbed or absorbed through the adsorption material or solution to form a solidified waste containing 14 C.

[0072] In some preferred embodiments, based on the activity concentration, the 14 C in the form of carbon dioxide is adsorbed, and after obtaining the solidified waste containing 14 C, the method further includes: detecting the activity concentration of the solidified waste containing 14 C to determine the activity concentration of 14 C in the solidified waste containing 14 C; when the activity concentration of 14 C in the solidified waste containing 14 C is lower than the preset concentration, performing cement solidification on the solidified waste containing 14 C.

[0073] Optionally, to prevent 14 C from being released in high or low temperature environments, it is necessary to perform cement solidification on the solidified waste containing 14 C, thereby completely sealing 14 C inside and preventing it from being released in special environments. First, it is necessary to perform an activity detection on the solid or liquid waste after adsorption or absorption to verify whether the current solidified waste containing 14 C meets the requirements of low-level radioactive waste. If it meets the requirements, subsequent disposal can be carried out according to the treatment method of cement solidification. Finally, the treatment of various forms of 14 C in the radioactive hydrogen-containing waste gas is achieved, meeting the emission standards.

[0074] Through the above steps S102 to S112, firstly, hydrogen is separated to reduce the risk of self-explosion in the subsequent oxidation process, and at the same time, the oxidation waste gas is first separated by osmosis 14Based on the activity concentration, adsorption is carried out to reduce the adsorption dosage and cost, thereby achieving the purpose of reducing the hydrogen concentration, reducing the risk of hydrogen oxidation and explosion, improving the safety performance, and at the same time reducing the dosage of the adsorption material and lowering the cost.

[0075] Example 2
