Description

201023964 VI. Description of the Invention: [Technical Field of the Invention] The present invention discloses a method and apparatus for optimal operation control of a concentrated reel system. More specifically, it relates to a honeycomb adsorption for a porous channel. In the concentrated reel system, the process of purifying and treating volatile organic compounds can be monitored immediately and the operation of the Han revolver and related operating conditions can be controlled in time to optimize the operation of the concentrated reel and [prior art] In today's industrial or high-tech industries, when volatile organic compounds are treated, the volatile organic compounds are collected by condensation at high concentrations, and concentrated at a low concentration and high air volume by physical adsorption. It is more economical to burn to a small incinerator or to recover it with a condensing unit. When the volatile organic matter is treated by the adsorption method, the volatile organic substance contained in the exhaust gas is used by using a porous substance containing an adsorbent (Vo·

Organic Compounds (V0Cs) or odors are physically or chemically adsorbed for the purpose of purifying the volatile organic waste gas. When the adsorbent is saturated, the adsorbed material must be removed by a desorption procedure before it can be reused. For example, in the process of PU synthetic skin, a large number of such methods are used such as methyi ethyl ketone (MEK) and f 〇 ene (ene) and isopropanol (is〇pr〇Pyl alc〇hol, IPA) and dimethyl A monomer such as carbamide (dmf) or the like, and the ratio of the solvents in the solution is about 6 〇 to 8 〇%. After that, it must be dried again to evaporate all the solvents; in the process of 201023964, an average of one yard of synthetic leather must be used with 35 grams of solvent, that is, one yard of synthetic leather must be discharged 350 grams of solvent. In the atmosphere, a large amount of v〇Cs pollution is caused. Based on the output of 90 million yards of Taiwan, 30,000 tons of organic solvents are emitted into the atmosphere every year, causing considerable environmental pollution. If the exhaust gas is not fully and effectively cleaned before discharge, it will seriously pollute the surrounding environment. After that, it will consume a lot of resources to eliminate the pollution. Furthermore, in order to effectively treat the organic waste gas generated in its related processes, the electronics industry uses a zeolite concentration runner and an incinerator to treat its organic waste gas. This method requires a large amount of incineration fuel and energy. It is not the most economical and practical method for removing organic waste gas. Taking the organic waste gas component produced by the semiconductor fab as an example, the exhaust gas discharged from the semiconductor industry often contains, for example, Dimethyl Sulfxide, N_Methyl Pyrolidone, and Ethyl Ammonium (2). -Aminoethanol), Dithi〇lethylene ❷ Glyco1, Dimethyl Sulfide, Isopropyl

Alcohol), acetone (Acet〇ne) and other compounds, after using the zeolite wheel to adsorb concentrated exhaust gas, 'burning in the incinerator at a temperature above 25 ° C ~ 9 ° C to decompose these volatile organic substances, stinky Gas and gas are most effective. At present, the exhaust gas treatment of volatile organic gases has been widely used in the semiconductor and optoelectronic industries by means of adsorption-concentrated zeolite rotor treatment combined with combustion incineration. Moreover, volatile organic compounds (VOCs) are one of the most common air pollutants in Taiwan. Their main sources are chemical industry 5 201023964 plant, petrochemical industry, printing industry, coating industry and emerging semiconductor and optoelectronic liquid crystal displays. industry. Due to the toxicity of VOCS and the characteristics that cause the formation of ozone and photochemical effects, if it is not controlled to be released into the atmosphere, it will bring considerable harm. At present, China has already legislated to strictly control the emission of VOCs in the petrochemical industry, coating industry, semiconductor industry, synthetic leather and dry cleaning related industries. In addition, the country's current development of thin film transistor liquid crystal display (Thin-Film Transistor Liquid- Crystal Display (TFT LCD) has also announced the implementation of "Opto-Electric Materials and Components Manufacturing Air Pollution Control and Emission Standards". The TFT-LCD industry, which is capable of increasing the emission of VOCs, can be properly controlled. The zeolite concentration runner system uses three consecutive procedures such as adsorption-desorption-concentration incineration to crack the VOCs into harmless H20 and co2. The equipment characteristics are suitable for treating high-flow, medium-low pollutant concentrations and VOCs containing one or more types. Exhaust gas can also be used in industries that emit thinner and near-perimeter temperatures. After the VOCs exhaust gas enters the system, it is firstly processed through a multi-pass tunnel honeycomb rotor, such as a honeycomb zeolite concentrate runner, which is coated with ceramic fiber paper with different proportions of ZSM-5 and Y-type zeolites. It can achieve the purpose of large adsorption amount of VOCs, small pressure loss of gas flow and light weight of the whole body. The VOCs pollutants can be adsorbed and concentrated and desorbed on the runner at the same time; usually the honeycomb rotor can be divided into three parts: larger The adsorption zone and two smaller and equivalent desorption zones and cooling zones. The first stage of adsorption 6 201023964 The procedure is to discharge the VOCs after entering the system to the atmosphere at a normal temperature, and then directly discharge to the atmosphere, and then enter the second stage of the desorption process due to the rotation of the wheel. The hot air is the hot air after the heat exchange between the preheated air at the exit of the cooling zone and the back end incineration system (about 150~300. 提供 to provide 'to make it into the runner to desorb the organic matter, then the outflow pollution The concentration of the substance is about 5 to 20 times that of the inflowing exhaust gas, and the organic matter desorbed and regenerated can be subjected to high temperature in the third stage of the heat incinerator (direct combustion furnace. Above 600 ° C or catalyst furnace at 25 ° eC) The above incineration or the process of condensing recovery and reuse of low temperature® can reduce the size of the subsequent exhaust gas treatment unit 'and save initial installation cost and running cost”

Mitsuma et al. (Mitsuma, H. Yamauchi, and T. Hirose, ^Analysis of VOC reversing adsorption and desorption characteristics for actual efficiency prediction for ceramic honeycomb adsorbent), J. Chem. Eng. Japan, 1998, 31 ( 2), ρρ·253-257) indicates that the rotational speed of the runner, the ratio of the decoupling area of the runner, the width of the rotor φ and the velocity of the desorbed airflow are the main operational parameters affecting the removal of VOCs by the zeolite runner, and the operational parameter relationships are summarized. The model can be adapted to the local field operation value; in addition, Chang et al.

The inference results are more reliable than the real-world operational efficiency verification. If the concentration of VOCs is too high or the regeneration temperature is too low, the treatment efficiency of the zeolite runner system will be significantly reduced under the limitation of mass and heat balance. In addition to the above operational parameters, it is estimated that the runner performance relationship is summarized.

These two conditions can be listed as the check factor of the system efficiency. The best performance of the zeolite runner system is also found in the study. The rotational speed needs to increase as the influx concentration of v〇Cs increases; while the concentration ratio when the system is reduced will contribute to the improvement of VOCs removal efficiency, but the reduced concentration ratio will relatively reduce the consumption of the back-end incineration energy. increase. In the system energy-saving research, a study on the two operating parameters of the regenerative temperature and the regenerative air volume in the real-world zeolite reel system, the system performance of the two parameters can be improved to 96.5%. It is greater than 95% of the original recommended operating value, and can also save 23% in the subsequent period of incineration fuel costs. However, the above research suggests that the influent concentration, the rotating speed, the concentrated concentration, the regeneration temperature, etc. are important operational parameters that determine the operating efficiency of the zeolite concentrate runner. The desorption concentration ratio will also determine the investment required for the operation of the back end incinerator. 201023964, the end of the system:: two: Dan manufacturers do not use the zeolite concentrate runner only in the center =: according to the adjuster's experience with the trial and error method t =: The operation of the real field operation has its complexity and difficulty, pending Further proposes a method and device for effectively controlling the operation of the deflated reels, in order to achieve the condensed reel (4) money secrets e in view of the above-mentioned conventional condensed reels in operation =: perfect '遂蝎 心 心 心 心 心 心 心 心The accumulated experience of the industry for many years has led to the development of a set of optimized methods and devices.

DETAILED DESCRIPTION OF THE INVENTION In order to fully understand the objects, features and effects of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings. , VOCs removal efficiency (t?r) definition of concentrated runner: 12 201023964 %=heart^^ beer..(%) PPmV(X) where ppmv(in) is the concentration of total hydrocarbons in the inlet, and ppm The enthalpy is the concentration value of the total carbon cerium compound for export, and the removal efficiency is the result obtained after the operation of the concentrating runner, and the operation of the concentrating runner is controlled by a plurality of factors, which are based on the control factors in the present invention. Propose one

The mathematical relation (1) is: N x(t - c *)x (r)a where: x

Td \b

xCcxV^ =K (1) N = speed of the concentrated runner (RPH); t = thickness of the concentrated runner (m); r = concentration ratio;

Td = desorption temperature (K = °C + 273.15); C = concentration of the total hydrogen barrier compound (ppm);

Vp = adsorption inlet wind speed (m/s); and the values a, b, c, d, c* and constant K can be obtained by several operations according to different concentrated runners and actual occasions. And the value a in the above mathematical relationship is between 0 and 3, and the values b, c, and d are between -3 and 3, and the value c* is concentrated with the runner. The mass transfer zone is related to a value equal to 0 to the thickness t of the concentrated runner. The above mathematical relationship (1) is an operation factor for controlling the concentrated revolving wheel in the optimization control of the concentrated revolving wheel, including: N-concentration runner 13 201023964 rotation speed, thickness of W agricultural revolving runner, 4 reduction ratio (= exhaust air volume / desorption air volume) Td-desorption temperature, c_ingress total carbon and nitrogen indifference value and external suction, inlet wind speed, wherein, in the factory, a fixed desert wheel is used. When the VOCs are treated, the concentration of the concentrated runner (1) and the total carbon ammonia at the inlet are determined. At this time, when setting one of the removal efficiency (6) targets, the factors to be considered include: N, r, T (^Vp The value is determined by the real-world operator, first setting two factors, such as selecting the desorption temperature and the adsorption inlet wind speed (vP) value, and then adjusting the reel speed (N) to determine the concentration ratio into the (four) Wei air volume. The removal efficiency can be achieved. The first figure is the method for optimizing the operation control of the I revolving wheel (4) in the present invention - the specific implementation step, wherein, firstly, one target value is removed after the shape is removed, and then Select the desorption temperature Td value, then, based on the input = PPmV (in) and selected Inhaling the wind and catching Vp, and then adjusting the speed of the concentrated reel (N). At this time, check whether the removal efficiency (6) is greater than or equal to the target value. If not, continue to adjust the rotation speed of the concentrated reel; if the peptide is equal to the target value, Then, the optimization adjustment is completed; when the removal efficiency (6) is greater than the target value, the desorption air volume is adjusted (ie, the concentration ratio is adjusted), so that the removal efficiency (Μ) is equal to the target value, that is, the optimization adjustment is completed; if still greater than the target For the value, the desorption air volume is continuously adjusted so that the removal efficiency is equal to the target value, and the optimization adjustment is completed. However, in the steps in the first figure above, the adjustment order for each operation factor is not absolute, and may be based on the actual Wei's operator needs to select the pre-set factors first, and then based on the mathematical relationship provided by the invention ^ (1) 'determine the value of other factors, and finally complete the optimal 201023964 operation control of the concentrated runner system. The mathematical relation (1) is established by the present invention, and is used to provide a data processor for performing the concentrated rotation operation of the present invention. Disconnect and adjust various operating parameters to achieve the desired V0Cs removal efficiency. Another embodiment of the optimized operation control device of the concentrated revolver system of the present invention is as shown in the second figure, wherein the V〇Cs exhaust gas flow (1) enters a concentrated transfer. The adsorption zone of the wheel 10 (the concentrating wheel in this embodiment is a rotary disk type, but may also be a rotary ring type) is subjected to adsorption treatment (the porous adsorbent in the present embodiment is zeolite, but may also be activated carbon). , 矽 或 or activated alumina), the cleaned clean air stream (II) is drawn and discharged through a first windmill 12, and the efficiency value of the concentrating wheel 10 for processing VOCs can be placed at the inlet of the concentrating wheel 10 The total hydrocarbon analyzers 42 and 44 after the front and the exit are respectively calculated by measuring the concentration of each V0Cs before and after the treatment. The method for detecting the total hydrocarbon analyzer is in accordance with the EPA's “Total _ Carbon in the discharge pipeline”. The automatic detection method for the content of hydrogen compounds and non-methane total hydrocarbons - on-line flame ionization detection method is tested. And part of the VOCs are passed into the cooling zone of the zeolite runner as the cooling gas stream (III), and the residual heat of the concentration wheel 10 after the thermal desorption is reduced. 'This gas stream passes through a first heat exchanger 52 to raise the temperature and then transforms. The high-temperature desorption gas stream (IV) is introduced into the desorption zone to desorb the organic waste gas adsorbing substance originally adsorbed on the concentration reel 10 at a high temperature, wherein the degassing gas flow rate can be controlled by a frequency converter 48 to control a second windmill 14 determines that the desorption concentration ratio of V〇Cs is defined as the desorbed clean gas stream II flow divided by the high temperature desorption gas flow IV flow entering the desorption zone. 15 201023964 The two concentrations v〇cs are desorbed from the concentration runner 10 and then enter a second heat exchanger 54 for preheating, and then introduced into an incinerator 6 for high temperature oxidation, and the cleaned gas after incineration passes the second heat exchange. The device 54 cools down and flows through the post-performance pipeline for discharge. The speed of the concentrating wheel 1 is controlled by a frequency converter 46 in combination with a driving motor 5 。. Since the desorption concentration ratio adjustment will change the flow rate of the high concentration VOCs entering the incinerator after desorption, the incinerator 6 has a thermocouple meter and controls the inflow fuel with the fuel inflow flow meter. Maintain a certain high temperature to effectively incinerate the concentrated V0Cs. ❹ wherein the concentration of the VOCs before and after the treatment is monitored by the total hydrocarbon analyzers 42 and 44, respectively, and the flow rate is monitored by an exhaust gas flow meter 32; and the rotational speed of the rotor is controlled by the inverter 46 in conjunction with the drive motor 50; The airflow volume is controlled by the frequency converter 48 in conjunction with the second windmill 14, and is monitored by a desorption air flow meter 34; and the desorption temperature is monitored by a desorption thermometer 36; and an actuator 38 is used to adjust the cooling airflow. (in) and the value of the high temperature airflow (IV), and the above related operational parameters are all connected to the terminal-data processor 80. The system can adjust the rotation speed according to the VOCs influent concentration change. If the VOCs inflow concentration increases, in order to avoid the adsorption penetration phenomenon in the reel adsorption area, the rotation speed of the reel should be increased, and the adsorption area should enter the desorption area early for heat. Desorption, and increasing the rotational speed also makes the desorption retention time shorter. At this time, it is necessary to increase the thermal energy to fully desorb the VOCs from the zeolite rotor. Increasing the heat energy can be achieved by increasing the desorption temperature or increasing the amount of desorbed air or increasing the two parameters. In order to cope with the increased air volume at this time, the 201023964 needs to add appropriate fuel to maintain the incineration temperature and ensure that v 〇Cs incineration efficiency, if the VOCs inflow concentration is reduced, the rotation speed of the rotor can be reduced, and then the desorption air volume can be reduced. Under the condition of less air volume, the fuel used in the back-end incinerator can also be reduced. . In addition, most of the fuel used in the incinerator is natural gas. If the outlet detects the detection of CHU concentration after incineration, it means that the combustion temperature is insufficient. At this temperature, the natural gas cannot be completely burned, so the detection of CH4 at the outlet end can be used to determine the combustion. Whether the temperature setting is appropriate or not, the treatment system can adjust the incineration temperature and air volume of the incinerator according to the concentration of the tail gas of the incinerator. The CH4 Handu surface needs to increase the combustion temperature or reduce the natural gas inflow rate. In addition, the air volume may be insufficient. Therefore, the combustion gas flow in the incinerator is caused by incomplete combustion caused by laminar flow, so the amount of desorption air needs to be increased. Furthermore, another specific embodiment of the optimized operation control device of the concentrated reel system of the present invention is shown in the third figure, and the device is substantially as shown in the second figure, and only the concentrating wheel 10 has only the adsorption zone. And the desorption zone, and the clean gas stream (11) flowing through the desorption zone can be further passed through the first heat exchanger 52 to raise the temperature, and the high temperature desorption gas stream (IV) is introduced into the concentration revolving wheel (10). Desorption zone, wherein the high temperature desorption gas stream (IV) is controlled by the actuator 38; and the desorbed VOCs are pumped by the second windmill into a final processing unit 70. Perform subsequent V〇Cs processing, and the final processing unit 70 may include a condenser, an incinerator, and a catalytic converter to complete the purification of the VOCs. The instant data processor provided in the invention can utilize the operation mode of the above-mentioned party 17 201023964 method to make the concentrated runner running performance achieve optimal control' and the terminal monitoring personnel can directly correct the operating parameters on the control platform according to the actual needs at the time. The zeolite runner can be adjusted and the operating parameters, VOCs processing efficiency and incineration fuel consumption can be immediately obtained.
