[0002] Since the workshop of the cigarette factory requires a strict temperature and humidity environment, the combined air conditioning humidification method currently used by the cigarette factory is mainly achieved by arranging a mist humidifier and a steam humidifier in the air duct in sequence. The principle is to achieve humidity control by directly spraying mist or high-temperature and high-pressure steam during the air supply process of the air conditioner. Under normal circumstances, the combined air conditioning of the cigarette factory will give priority to the mist humidification, but when the mist humidification effect does not meet the standard, the mist humidification and steam humidification will be turned on at the same time.

[0003] However, when both micro-mist humidification and steam humidification are turned on at the same time, the droplets generated by micro-mist humidification cannot be used efficiently. A certain proportion of droplets that are not completely vaporized will remain on the wall of the equipment in the form of water columns. In addition, the high-level heat energy carried by the steam in steam humidification cannot be directly used for micro-mist humidification, which leads to the inability of the combined air conditioner to effectively realize the cascade utilization of the heat energy carried by high-temperature and high-pressure steam in the humidification process.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0018] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

[0019] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims.

Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described in some examples may be combined in other examples.

[0020] See also Figure 1 , Figure 1 An overall flow chart of a combined air conditioning and humidification method based on steam and mist impact flow provided in an embodiment of the present application is shown.

[0021] like Figure 1 As shown, the combined air conditioning humidification method based on steam and mist impingement flow can at least include the following steps: Step 101: Acquire humidification parameters of the combined air conditioner, and determine the humidity content of the supply air according to the humidification parameters.

[0022] In the embodiment of the present application, the combined air conditioning humidification method based on the steam and micro-mist collision flow state can be applied to, but is not limited to, a microprocessor or a microcontroller. In the combined air conditioning humidification process based on the steam and micro-mist collision flow state, the humidity content of the supply air is determined by the humidification parameters of the combined air conditioner, and then the micro-mist adjustment amount and the steam adjustment amount are calculated according to the humidity content of the supply air and the preset linear regression function, so that a signal for controlling the opening of the micro-mist and steam valve can be generated according to the micro-mist adjustment amount and the steam adjustment amount, so that an appropriate amount of micro-mist collides with steam, and the high-quality thermal energy of high-temperature and high-pressure steam is used for the vaporization of droplets in the micro-mist humidification airflow, which improves the efficiency of micro-mist humidification and also realizes the cascade utilization of high-quality thermal energy.

[0023] Specifically, in the combined air conditioning humidification process based on steam and mist impact flow, the humidification parameters of the combined air conditioning set by the user according to personal preferences, seasonal changes or specific process requirements can be obtained through devices such as a touch screen, a button panel or a remote control terminal.

[0024] Furthermore, the saturated water vapor pressure at the supply air temperature can be calculated by the Antoine equation (an empirical formula for estimating the saturated vapor pressure of pure substances at different temperatures) and the supply air temperature in the humidification parameter, and then the water vapor partial pressure can be obtained by multiplying the saturated water vapor pressure by the relative humidity in the humidification parameter, so that the supply air moisture content can be calculated by the following formula: Where d is the moisture content of the supply air, expressed in grams of water vapor per kilogram of dry air (g / kg dry air), expressed as g / kg da Or abbreviated as g / kg; φ is the relative humidity in the humidification parameter, the unit is percentage (%), usually expressed as "%RH"; P v is the partial pressure of water vapor, in Pascal (Pa); P is the total air pressure, in Pascal (Pa), which can be measured by but is not limited to a mercury barometer, an air box barometer or a digital pressure sensor.

[0025] As an option in the embodiment of the present application, the humidification parameters include relative humidity and desired temperature; The humidity content of the supply air is determined based on the humidification parameters, including: Determine isotherms in the psychrometric diagram according to relative humidity, and determine iso-relative humidity lines in the psychrometric diagram according to expected temperature; Based on the intersection of the isotherms and relative humidity lines, the humidity content of the supply air is determined.

[0026] Specifically, in the process of determining the humidity content of the supply air according to the humidification parameters, the iso-relative humidity lines corresponding to the relative humidity in the humidification parameters can be found in the humidification diagram, and the isotherms corresponding to the expected temperature in the humidification diagram can be found according to the expected temperature in the humidification parameters.

[0027] Then, the humidity content corresponding to the intersection point of the two lines in the psychrometric diagram can be found, and the humidity content can be used as the supply air humidity content.

[0028] It should be noted that the three axes in the psychrometric diagram represent temperature, moisture content and enthalpy value, respectively. The axes representing temperature and moisture content are perpendicular straight lines, and the axis representing enthalpy value is a curve. The three axes form a concave polygon. In addition, the change trend of the iso-relative humidity line is similar to that of the curve.

[0029] Step 102: Calculate the adjustment amount based on the humidity content of the supply air and a preset linear regression function.

[0030] Specifically, after determining the humidity content of the supply air, the mist flow rate and steam flow rate required to achieve the humidity content of the supply air can be calculated based on the humidity content of the supply air and a preset linear regression function, so that the adjustment amount can be calculated, wherein the adjustment amount includes the steam adjustment amount and the mist adjustment amount.

[0031] It is understandable that the variables of the preset linear regression function include air humidity, mist flow, carrier gas flow, steam flow, air volume, air temperature (i.e., desired temperature), relative humidity, and heat required for vaporization of mist droplets. The expression of the preset linear regression function may be, but is not limited to,: Among them, Ф is the moisture content of the supply air, in grams of water vapor per kilogram of dry air (g / kg dry air); F1 is the mist flow rate, in kilograms per hour (kg / h); F2 is the carrier gas flow rate, in kilograms per hour (kg / h); F3 is the steam flow rate, in kilograms per hour (kg / h); F4 is the supply air volume, in cubic meters per hour (m³ / h); T is the supply air temperature, in degrees Celsius (℃); φ is the relative humidity, in percentage (%); Q1 is the heat required for the vaporization of the mist droplets, in joules (J).

[0032] It should be noted that A, B, C, D, E, F, G and a, b, c, d, e, f, g are coefficients and exponents in the function, which are constants and can be obtained through multiple experiments and test data. For example, the appropriate coefficients A, B, C, D, E, F, G and exponents a, b, c, d, e, f, g can be calculated by the least squares method, the air humidity content Φ determined by the enthalpy-humidity diagram, the air volume F4 calculated by the anemometer and the area method, the air temperature T and relative humidity φ set by the user, the heat Q1 required for the vaporization of the micro-mist droplets calculated by the formula, and the micro-mist flow F1, carrier gas flow F2, and steam flow F3 measured by various flow meters (such as ultrasonic flow meters, laser scattering flow meters, impact flow meters, vortex flow meters, orifice differential pressure flow meters, turbine flow meters, rotor flow meters, soap film flow meters, etc.).

[0033] After calculating the micro mist flow and steam flow required to achieve the moisture content of the supply air, the difference between the required value and the actual value can be calculated based on the actual micro mist flow and actual steam flow measured by the flow meter, which is the adjustment amount.

[0034] As another option of the embodiment of the present application, before calculating the adjustment amount based on the humidity content of the supply air and the preset linear regression function, the method further includes: When it is detected that the steam in the impact zone of the combined air conditioner is in an overheated state, the current temperature in the impact zone is obtained; wherein the current temperature is higher than a preset temperature; According to the current temperature and the preset first formula, the ratio expression of steam quality to micro mist quality is determined; Based on the ratio expression, determine the constraints.

[0035] Specifically, before calculating the adjustment amount based on the moisture content of the air supply and the preset linear regression function, the state of the steam in the impact zone of the combined air conditioner can also be detected. When it is detected that the steam in the impact zone is in an overheated state, that is, the steam is in a high temperature and high pressure state, at this time, the temperature of the steam is much higher than its boiling point at standard atmospheric pressure (that is, much higher than 100°C) and the pressure it bears is significantly higher than the standard atmospheric pressure, so it can be converted into 100°C steam by releasing heat.

[0036] Next, the temperature of the steam in the superheated state, that is, the current temperature in the impact zone, can be obtained through, but not limited to, thermocouples or platinum resistance temperature detectors and other devices, wherein the current temperature is higher than a preset temperature, which is 100°C.

[0037] After obtaining the current temperature, the ratio expression of steam quality to mist quality can be obtained by the preset first formula, wherein the preset first formula includes the following three formulas: Among them, Q1 is the heat required for the vaporization of micro mist droplets, in joule (J); Q2 is the heat released when the superheated steam is converted into 100°C steam, in joule (J); m1 is the mass of micro mist, in kilogram (kg); m2 is the mass of steam, in kilogram (kg); T is the current temperature, in degrees Celsius (℃); ΔH is the latent heat of vaporization of water, in J / kg, and the value here is 2260000 J / kg; Cp is the specific heat capacity of water, in J / (kg·°C), and the value here is 4200 J / (kg·°C).

[0038] According to the above formula, the ratio expression of the micro mist mass m1 to the steam mass m2 can be obtained. For example, when the current temperature is 600°C, the expression obtained according to the above formula is: Therefore, the corresponding constraint conditions can be determined according to this expression, such as: the steam mass is 1.2 times the micro mist mass, the steam mass is greater than 1.1 times the micro mist mass, etc.

[0039] As another option of the embodiment of the present application, the adjustment amount is calculated based on the humidity content of the supply air and a preset linear regression function, including: According to the humidity content of the supply air and the preset linear regression function, the target steam volume and the target micro-mist volume are calculated; Calculating a first steam adjustment amount based on a target steam amount and an actual steam amount received, and calculating a first fine mist adjustment amount based on a target fine mist amount and an actual fine mist amount received; When it is detected that the target steam amount and the target fine mist amount meet the constraint conditions, an adjustment amount is determined based on the first steam adjustment amount and the first fine mist adjustment amount; When it is detected that the target steam volume and the target micro-mist volume do not meet the constraint conditions, the preset linear regression function is optimized to obtain the target function; According to the moisture content of the supply air and the objective function, the second steam adjustment amount and the second fine mist adjustment amount are calculated; An adjustment amount is determined based on the second steam adjustment amount and the second fine mist adjustment amount.

[0040] Specifically, after determining the constraint conditions, the target steam volume and target mist volume (i.e., the steam flow rate and mist flow rate required to achieve the above-mentioned supply air moisture content) can be calculated based on the supply air moisture content and a preset linear regression function. The calculation method can refer to the other embodiments mentioned above.

[0041] Next, the difference between the target steam volume and the actual steam volume measured by the flow meter can be calculated to obtain the first steam adjustment amount, and the first micro-mist adjustment amount can be obtained in the same way. Thereafter, it can be judged whether the target steam volume and the target micro-mist volume meet the constraint conditions. When the judgment result is that the constraint conditions are met, the first steam adjustment amount and the first micro-mist adjustment amount can be used as the calculated adjustment amount, but not limited to; when the judgment result is that the constraint conditions are not met, the preset linear regression function can be optimized to obtain the objective function, so that the second steam adjustment amount and the second micro-mist adjustment amount can be calculated according to the humidity content of the supply air and the objective function according to the aforementioned method, and the second steam adjustment amount and the second micro-mist adjustment amount can be used as the calculated adjustment amount. Among them, the optimization method can be but not limited to the gradient descent method, the cross-validation method, etc.

[0042] As another option of the embodiment of the present application, the adjustment amount is determined based on the first steam adjustment amount and the first fine mist adjustment amount, including: Calculate the carrier gas adjustment amount based on the target micro mist volume and the preset mixing ratio; The first steam adjustment amount, the first fine mist adjustment amount and the carrier gas adjustment amount are used as adjustment amounts.

[0043] Specifically, in the process of determining the adjustment amount according to the first steam adjustment amount and the first micro-mist adjustment amount, the carrier gas adjustment amount can be first calculated according to the target micro-mist amount and the preset mixing ratio, that is, the target micro-mist amount is divided by the preset mixing ratio, and the quotient obtained is the carrier gas adjustment amount. For example, when the target micro-mist amount is 50kg / h and the preset mixing ratio is 2:7 (that is, two-sevenths), the carrier gas adjustment amount can be obtained as 175kg / h.

[0044] Then, the first steam adjustment amount, the first fine mist adjustment amount, and the carrier gas adjustment amount may be used as the calculated adjustment amounts.

[0045] Step 103: Calculate the valve opening based on the adjustment amount and the preset proportional value, and generate a control signal according to the valve opening.

[0046] Specifically, after calculating the adjustment amount, since the valve opening is related to the adjustment amount (if the adjustment amount is a positive value, the valve opening becomes larger, and if the adjustment amount is a negative value, the valve opening becomes smaller), the change value of the valve opening can be obtained based on the product of the adjustment amount and the preset positive proportional value, and then the required valve opening can be determined based on the change value and the current valve opening.

[0047] Furthermore, a corresponding control signal may be generated according to the determined desired valve opening to control the valve opening of the corresponding valve to achieve the valve opening required to meet the moisture content of the supply air.

[0048] As another option of the embodiment of the present application, the preset proportional value includes a preset first proportional value, a preset second proportional value and a preset third proportional value; The valve opening is calculated based on the adjustment amount and the preset proportional value, and a control signal is generated according to the valve opening, including: Calculating the first valve opening according to the steam adjustment amount and the preset first proportional value; Calculate the second valve opening according to the micro-mist adjustment amount and the preset second proportional value; Calculating the third valve opening according to the carrier gas adjustment amount and the preset third proportional value; A control signal is generated according to the first valve opening, the second valve opening, and the third valve opening.

[0049] Specifically, in the process of calculating the valve opening according to the adjustment amount and the preset proportional value, since the preset proportional value includes a preset first proportional value, a preset second proportional value and a preset third proportional value, the first valve opening can be calculated according to the steam adjustment amount and the preset first proportional value, the second valve opening can be calculated according to the micro-mist adjustment amount and the preset second proportional value, and the third valve opening can be calculated according to the calculated carrier gas adjustment amount and the preset third proportional value, wherein the calculation method can refer to the previous embodiment.

[0050] Then, three corresponding control signals can be generated according to the first valve opening, the second valve opening and the third valve opening, which are used to control the opening of the steam valve, the opening of the micro-mist valve and the opening of the carrier gas valve to be consistent with the first valve opening, the second valve opening and the third valve opening.

[0051] As another option of the embodiment of the present application, the preset proportional value includes a preset first proportional value and a preset second proportional value; The valve opening is calculated based on the adjustment amount and the preset proportional value, and a control signal is generated according to the valve opening, including: Calculating the first valve opening according to the steam adjustment amount and the preset first proportional value; Calculate the second valve opening according to the micro-mist adjustment amount and the preset second proportional value; Calculate the third valve opening according to the second valve opening and a preset second formula; A control signal is generated according to the first valve opening, the second valve opening, and the third valve opening.

[0052] Specifically, in the process of calculating the valve opening according to the adjustment amount and the preset proportional value, since the preset proportional value includes a preset first proportional value and a preset second proportional value, the first valve opening can be calculated according to the steam adjustment amount and the preset first proportional value, and the second valve opening can be calculated according to the micro mist adjustment amount and the preset second proportional value.

[0053] Next, the third valve opening can be calculated based on the second valve opening and a preset second formula, wherein the preset second formula represents the numerical relationship between the second valve opening and the third valve opening (such as a linear relationship, a quadratic function relationship, etc.), which can be determined through multiple experiments and test data, such as the second valve opening being half of the third valve opening.

[0054] Thereafter, three corresponding control signals can be generated according to the first valve opening, the second valve opening and the third valve opening, which are used to control the opening of the steam valve, the opening of the micro-mist valve and the opening of the carrier gas valve to be consistent with the first valve opening, the second valve opening and the third valve opening.

[0055] See also Figure 2 , Figure 2 A distribution diagram of the impingement flow of steam and mist provided in an embodiment of the present application is shown.

[0056] like Figure 2As shown, the air is heated or cooled according to the workshop temperature requirements, and then the treated air is controlled to enter the impact zone according to the workshop humidity requirements. At this time, the steam humidification nozzle and the micro-mist humidification nozzle are arranged on both sides of the air duct respectively, and the high-pressure and high-temperature steam and the mixture of micro-mist and carrier gas are ejected from these nozzles in opposite directions, thereby generating a collision and forming an impact flow state. In the impact zone, the impact flow state can produce a strong turbulent zone, which accelerates the heat exchange between the cold and hot fluids, thereby realizing the use of high-enthalpy high-temperature and high-pressure steam to heat and vaporize the low-enthalpy normal-temperature micro-mist, so that more micro-mist can be vaporized in the air duct, which improves the humidification efficiency and realizes the cascade utilization of energy. After that, the humidified air will be sent into the workshop through the air supply fan.

[0057] See also Figure 3 , Figure 3 A control principle diagram of a combined air conditioning and humidification method based on steam and mist impact flow provided in an embodiment of the present application is shown.

[0058] like Figure 3 As shown in the figure, valve 1 is a carrier gas valve, valve 2 is a micro-mist valve, and valve 3 is a steam valve; the impingement flow is formed by spraying multiple parallel and oppositely arranged nozzles; the carrier gas is obtained by exhausting air that has been heated or cooled; and the micro-mist is formed by purified water passing through an atomizer.

[0059] It can be understood that when it is detected that the humidity in the workshop is inconsistent with the expected humidity, the required humidity content (i.e. the above-mentioned supply air humidity content) will be determined based on the expected temperature and humidity (i.e. the above-mentioned humidification parameters) and the enthalpy-humidity diagram, and then the three valve openings can be calculated according to the required humidity content according to the aforementioned method, thereby controlling the flow rates of carrier gas, micro-mist and high-temperature and high-pressure steam respectively.

[0060] It is worth noting that the micro mist will form a mixed gas with the carrier gas before spraying, so that the micro mist droplets are sprayed by the carrier gas. Among them, the ratio of the carrier gas flow rate to the micro mist flow rate can be controlled by valve 1 (that is, the carrier gas valve). For example, if the micro mist flow rate is X, the carrier gas flow rate Y is calculated according to the set ratio, and then the opening Z of valve 1 is controlled to achieve the output carrier gas flow rate Y, thereby realizing the carrier gas ratio control.
