Description

METHOD OF DESIGNING A GAS FILTER SHAPE TAKING INTO CONSIDERATION THE CHARACTERISTICS OF THE ADSORBENT ITSELF AND THE ADSORPTION CHARACTERISTICS OF ADSORBENT AND POLLUTED GAS}

The following description is based on the appropriate shape and size for the intended adsorption capacity and life expectancy by predicting the filtration performance and filtration life according to the size and design shape of the portable gas mask filter, CFC filter for military vehicles or collective protection facilities. The present invention relates to a method of designing a gas filter shape in consideration of the characteristics of the adsorbent itself and the adsorption characteristics of the adsorbent and pollutant gas.

The NBC filter and the toxic gas removal filter are composed of a particle filter (HEPA filter) for removing particulate components in the inlet air and an adsorbent for removing toxic gases in the air. When designing the shape of the filter, the filter should be designed with a suitable filter shape for the platform or installation on which the filter will be installed or installed, such as a gas mask or collective protection facility, and the filter performance, life span and In addition, the pressure drop according to the shape of the filter to determine the respiratory resistance of the gas mask or the energy requirements of the collective protection facility should be calculated.

Currently, filters attached to military or civil gas masks have a relatively simple shape, such as cylindrical or trapezoidal. As a result, it is possible to produce a manufacturing process that is not difficult to determine the adsorption performance, pressure drop characteristics, filter life, and the like of the filter at a low cost, and to obtain a filter performance, a lifetime, and other filter characteristics of the resulting product. However, the gas mask of the future may be configured in one piece with the helmet, so that the filter is designed to be attached to the gas mask face part in a flat shape or inserted into the gas mask face part in a built-in type, such as an irregular shape can be required. In this case, it can be economical and time-consuming to manufacture and perform various kinds of irregularly shaped filters individually, and save time and budget if performance can be predicted through modeling only with shape design drawings and packing material characteristics data. can do. Currently, the 3D shape design program and the fluid analysis technique using fluid analysis are used for the filter design or the adsorption bed design. However, this is a simple flow analysis process that does not consider the adsorption characteristics of the pollutant gas on the adsorption medium. There is a limit to predicting the accurate adsorption life of CBR filters installed in military equipment such as helicopters and helicopters, and only accurate adsorption life can be estimated by actual adsorption experiments.

A gas filter such as a gas mask filter, a NBC filtration module of a military mobile vehicle, and a helicopter is filled with an adsorbent for blocking the inflow of polluted gas. At present, in the design of gas filters filled with adsorbents, especially in the design of irregularly shaped new filters, the adsorption behavior of air flow paths for a particular gas has not been predicted. The step of checking the gas adsorption life was performed. Even if the shape design is performed for the filter, if there is no reliable adsorption life prediction technology, the prototype is manufactured based on arbitrary assumptions about the performance of the shape design result. The manufacturing process is repeated. In this case, prototyping is costly and time consuming.

It is an object of an embodiment to provide a method of designing a gas filter shape for rational shape design of a gas mask, a mobile vehicle, and a collective shelter filter.

1 to 5, a method of designing a gas filter shape (hereinafter, a method of designing a gas filter shape) in consideration of the characteristics of the adsorbent itself and the adsorption characteristics of the adsorbent and contaminant gas may be performed. Adsorption saturation along the gas flow path, gas leakage concentration at the gas outlet, etc. can be calculated to predict the filter saturation life due to the influx of polluted gas, thereby determining the rationality of the filter shape design. The method of designing the gas filter shape considers not only the flow conditions and the shape conditions, but also the characteristics of the contaminated gas, the characteristics of the packed adsorbent, and the adsorption characteristics between the contaminated gas and the packed adsorbent in determining the rationality of the shape design. It is possible to judge the rationality of the shape design at a high level of reliability.

The method for designing a gas filter shape includes designing a shape of a three-dimensional filter through a three-dimensional shape design program (S110), inputting characteristics of the contaminated gas passing through the three-dimensional filter into a database (S120), and 3 Inputting the flow conditions of the contaminated gas passing through the inlet, the internal space, and the outlet of the dimensional filter into the database (S130), and inputting the characteristics of the packed adsorbent provided in the three-dimensional filter into the database (S140); Inputting the adsorption characteristics between the gas and the packed adsorbent into the database (S150), the shape of the three-dimensional filter, the characteristics of the contaminated gas, the flow conditions of the contaminated gas, the properties of the packed adsorbent and the adsorption properties between the contaminated gas and the packed adsorbent; On the basis of, calculating the flow analysis and adsorption behavior modeling simultaneously using a fluid analysis program (S160), to the spherical model Performing a performance test and comparing the results of the performance test with the flow analysis and adsorption behavior modeling data for the spherical model to correct the parameter values of the fluid analysis program (S170), the outlet concentration of the three-dimensional filter Calculating a change to determine the adsorption life of the three-dimensional filter (S180), adjusting the value of at least one of the characteristics of the contaminated gas, the characteristics of the packed adsorbent, and the adsorption characteristics between the contaminated gas and the packed adsorbent (S190). For example, the method may include adjusting a characteristic value applied to a function arbitrarily established and inputted by a user for a flow analysis program or a user's adsorption behavior analysis, and simultaneously regenerating flow analysis and adsorption behavior modeling (S200). .

In step S110, the shape of the 3D filter may be designed through the 3D shape design program. The three-dimensional geometric design program can be, for example, a three-dimensional geometric design program with AutoCAD, ACIS, CATIA, Creo Elements / Direct Modeling, Autodesk Inventor, JTOpen, NX, Parasolid, Creo Parametric, Solid Edge, SOLIDWORKS, or similar. Can be. The user can design a new three-dimensional shape filter through the three-dimensional shape design program. The three-dimensional filter may be manufactured to correspond to the shape of the newly developed gas mask, and for example, may be manufactured so that the height protruding from the gas mask is minimal.

In step S120, the user may input the characteristics of the contaminated gas passing through the three-dimensional filter into the database. For example, the characteristic of the polluted gas may include at least one of a polluted gas component, a polluted gas concentration, and a polluted gas temperature. The user can input the characteristic information of the polluting gas of the environment in which the filter to be designed is used into the database. The nature of the contaminated gas can be modified according to the use environment of the three-dimensional filter.

In step S130, the user may enter the flow conditions of the contaminated gas passing through the inlet, the internal space and the outlet of the three-dimensional filter in the database. The flow conditions of the polluted gas may be used in the computerized fluid dynamics (CFD) program of step S160. For example, the fluid analysis program may be Ansys fluent, Star-CD, Star-CCM +, OpenFOAM, Autodesk CFD, FLOW-3D or Barracud.

In step S140, the user may input the characteristics of the packed adsorbent provided in the three-dimensional filter into the database. The properties of the packed adsorbent may include at least one of adsorbent component, adsorbent density, adsorbent particle shape, adsorbent particle size, porosity, and adsorbent packing density inside the three-dimensional filter. For example, the packed adsorbent may be activated carbon, ACF, Zr (OH) 4, MOF-based nanopore or zeolite-based adsorbent material, and the like, and any one of the characteristic values may be input to a database. By designing the gas filter shape, the user can optimize the design by adjusting the characteristic values of the packed adsorbent. For example, if the flow analysis and adsorption behavior modeling were simultaneously calculated according to the originally designed three-dimensional filter geometry, if the filter life did not meet the expected values, the component of the adsorbent was replaced with a stronger one, or the adsorbent density was increased. The filter life can be adjusted to reach the expected value by increasing the packing density of the adsorbent in the three-dimensional filter.

In step S150, the user may enter the adsorption characteristics between the polluting gas and the packed adsorbent into the database. Adsorption characteristics between the contaminated gas and the packed adsorbent can be obtained through literature review or experiment. The user can enter and update the adsorption properties in the database.

In step S160, the user uses a fluid analysis dynamics program based on the shape of the three-dimensional filter, the characteristics of the contaminated gas, the flow conditions of the contaminated gas, the characteristics of the packed adsorbent and the adsorption characteristics between the contaminated gas and the packed adsorbent. Flow analysis and adsorption behavior modeling can be calculated simultaneously. Through adsorption behavior modeling, as shown in FIGS. 3 to 5, the filter flow rate distribution and the flow vector, the pressure drop inside the filter, and the adsorption saturation distribution in the filter over time can be visually represented. This allows the user to distinguish inefficient areas and to optimize the shape of the three-dimensional filter. For example, when observing the distribution of adsorption saturation in the filter over time, if the set saturation is not exceeded until the life time is reached, the region can be regarded as an inefficient region. When the inefficiency region is identified, the user can reshape the flow analysis and adsorption behavior modeling simultaneously by performing a shape change to remove the inefficiency region.

For example, in step 160, the user inputs into a fluid analysis program as a filter performance prediction technique and calculates from the adsorption equilibrium test data, adsorption breakthrough test data, etc. for the adsorbent to predict the adsorption saturation or reaction progression by location. Modeling result by inputting adsorption characteristics and reaction characteristics data of adsorbent such as gas adsorption rate function [Y = f (x), Y = adsorption amount, x = adsorption time] Applicable to the calculation.

Referring to Fig. 3, reference numeral 21 denotes a filter air discharge area during respiration (operation of the pump, in the case of a facility filter), and reference numeral 22 denotes air inflow into the filter from the atmosphere (outside, in the case of a facility filter). It represents an area. 23 is a visual representation of the flow rate vector of the filter air outlet during breathing (operational pump operation), and 24 is a visual representation of the air flow inside the filter during respiration (operational operation of the pump). It is represented by. In this way, the flow analysis can verify whether the flow occurs smoothly in the designed three-dimensional filter.

Referring to FIG. 4, reference numeral 31 denotes a negative pressure region of the air discharge part by respiration, and reference numeral 32 denotes an atmospheric pressure region of the filter air inlet part by respiration. The flow analysis makes it easy to visually identify the pressure drop inside the designed three-dimensional filter.

Referring to FIG. 5, reference numeral 41 denotes a polluted gas unsaturated region, and reference numeral 42 denotes a polluted gas saturation region. Adsorption behavior modeling makes it easy to visually identify the adsorption saturation in a three-dimensional filter over time. In addition, these result values reflect the characteristics of the packed adsorbent, the properties of the polluted gas, and the adsorption characteristics between the polluted gas and the packed adsorbent, not only the shape of the three-dimensional filter and the flow conditions of the polluted gas. The accuracy may be higher.

In step S170, the user performs a performance test on the existing spherical model or the test simple model, and compares the results of the performance test with the flow analysis and adsorption behavior modeling data for the spherical model to determine the fluid analysis program. Parameter values can be corrected. In step S170, the step of analyzing a spherical model or existing shape (example model) fluid analysis results (S171), the step of actually performing a performance test for the spherical model or existing shape (S172), the spherical model or existing shape test Comparing the result with the actual performance test value (S173) and reviewing the modeling accuracy, if the modeling accuracy is low based on the results in step S173 may include the step of correcting the parameter (S174).

In step S180, the user may calculate the change in the outlet concentration of the three-dimensional filter to determine the adsorption life of the three-dimensional filter. For example, the user may determine the point at which the filter outlet concentration exceeds the leak allowable concentration as the filter adsorption life (see FIG. 8).

In step S190, the user relates to the characteristics of the contaminated gas, the characteristics of the packed adsorbent, the adsorption characteristics between the contaminated gas and the packed adsorbent, the hydrodynamic theoretical parameters related to the fluid behavior, and the adsorption behavior expression related to the adsorption behavior of the gas. At least one value of the parameter may be adjusted. It can be applied again to the designed three-dimensional filter shape.

In step S200, the user may simultaneously recalculate flow analysis and adsorption behavior modeling. The user can repeat the preceding steps until the desired filter adsorption life is reached to determine the final packed adsorbent properties.

6 is a cross-sectional view schematically showing the shape of a three-dimensional filter according to an embodiment, and FIG. 7 is a cross-sectional view schematically showing a state in which an inefficient region is removed from FIG. 6.

Referring to FIGS. 6 and 7, the step of simultaneously calculating the flow analysis and the adsorption behavior modeling (S160, see FIG. 1) may include: dividing the internal space of the three-dimensional filter into a plurality of spaces, and each of the plurality of spaces. Comparing the adsorption behavior to determine the inefficiency region. For example, the three-dimensional designed filter shape may include an inlet 51, a body 52, and an outlet 53. The gas may be introduced through the inlet 51, adsorbed by the body 52, and discharged through the outlet 53. An adsorbent may be provided in the body part 52, and the internal space of the body part 52 may be divided into a plurality of spaces A-F. The adsorption behavior of each of the plurality of spaces can be compared with each other and the inefficiency region can be determined. For example, when the filter reaches the adsorption life, the adsorbent in most of the spaces may be saturated, but the saturation of the portion where the flow of contaminated gas does not reach smoothly, i.e., the inefficient region, may be relatively low. In the inefficient region may be less adsorption even when the other region is completely adsorbed. For example, the space C and the space F of the spaces shown in FIG. 6 may be inefficient regions.

Determining the inefficiency region comprises measuring the adsorption saturation of each of the plurality of spaces over time. After the set time has elapsed, the step of determining the area where the adsorption saturation does not reach the set saturation value as an inefficient area. For example, if the space C is determined to be an inefficient region, the user may return to the step of designing the shape of the three-dimensional filter to remove the inefficient region, for example, the space C and the space F. In this way the user can make the filter shape more compact.

Referring to FIG. 8, the outlet concentration of the three-dimensional filter may be determined based on the breakthrough concentration. During the time when the pollutant gas enters, i.e., the filtration time, the breakthrough concentration increases gradually from zero to a certain time. The point at which the breakthrough concentration exceeds the allowable leakage concentration may be the filter adsorption life.
