其次，說明上述本實施形態之排氣淨化設備之運轉控制方法。 Next, an operation control method of the exhaust gas purification apparatus of the above embodiment will be described.
當使用送風機10將含有可燃性有害成分的排氣送進連續再生式濃縮裝置2時，排氣係在旋轉之吸附體6的吸附區6a，將可燃性有害成分吸附除去之後，被排出至外氣。 When the exhaust gas containing the combustible harmful component is sent to the continuous regenerative concentration device 2 by the blower 10, the exhaust gas is adsorbed and removed by the flammable harmful component in the adsorption zone 6a of the rotating adsorbent 6, and then discharged to the outside. gas.
被吸附體6吸附之可燃性有害成分，係藉由旋轉而被送至再生區6b，而且在再生區6b藉由從脫附用空氣供給裝置8的供給導管26所供給的脫附用空氣，而從吸附體6被脫附除去。 從吸附體6被除去的可燃性有害成分係含有在脫附用空氣中，並作為含有可燃性有害成分的排出空氣而被排出至排出導管34。在此，排出空氣係比被供給至連續再生式濃縮裝置2的排氣含有較高濃度的可燃性有害成分。 The flammable harmful component adsorbed by the adsorbent 6 is sent to the regeneration zone 6b by rotation, and the desorbing air supplied from the supply conduit 26 of the desorption air supply device 8 in the regeneration zone 6b is The adsorbent 6 is removed and removed. The combustible harmful component removed from the adsorbent 6 is contained in the desorbing air, and is discharged to the discharge duct 34 as exhaust air containing a combustible harmful component. Here, the exhaust air contains a higher concentration of combustible harmful components than the exhaust gas supplied to the continuous regenerative concentration device 2.
在再生區6b被加熱後之吸附體6，係在冷卻區6c被排氣冷卻而成為能夠有效率地吸附可燃性有害成分之狀態。 The adsorbent 6 heated in the regeneration zone 6b is cooled by exhaust gas in the cooling zone 6c, and is in a state in which the combustible harmful component can be efficiently adsorbed.
從冷卻區6c被排出的空氣，係在混合室24與從燃燒室16供給的高溫氣體混合且加熱之後，經由供給導管26而被供給至吸附體6的再生區6b。 The air discharged from the cooling zone 6c is mixed and heated by the high temperature gas supplied from the combustion chamber 16 in the mixing chamber 24, and then supplied to the regeneration zone 6b of the adsorbent 6 via the supply conduit 26.
被排出至排出導管34之含有可燃性有害成分的排出空氣，係經由打開狀態的遮斷風門36，依序通過外氣引進風門38、送風機40、分叉導管42及打開狀態的供給風門18a而供給至蓄熱式排氣淨化裝置4的蓄熱室1塔12。 The exhaust air containing the combustible harmful component discharged to the discharge duct 34 is sequentially introduced into the damper 38, the blower 40, the branch duct 42 and the supply damper 18a in the open state via the damper 36 in the open state. It is supplied to the regenerator 1 tower 12 of the regenerative exhaust gas purification device 4.
排出空氣係在蓄熱室1塔12被加熱之後，流入燃燒室16而燃燒除去可燃性有害成分且被淨化。因為燃燒室16係設置有燃燒器10a，故能夠將燃燒室16的溫度維持在能夠充分地將可燃性有害成分予以燃燒除去之溫度。被淨化後的氣體係在蓄熱室2塔14蓄熱之後，依序通過打開狀態的排氣風門20b及分叉導管44而從排氣導管46排出。 The exhaust air is heated in the regenerator 1 tower 12, and then flows into the combustion chamber 16 to be burned to remove combustible harmful components and purified. Since the combustion chamber 16 is provided with the burner 10a, the temperature of the combustion chamber 16 can be maintained at a temperature at which the combustible harmful component can be sufficiently burned and removed. The purified gas system is stored in the regenerator 2 tower 14 and sequentially discharged from the exhaust duct 46 through the open exhaust damper 20b and the branch conduit 44.
在此，於蓄熱式排氣淨化裝置4，為了有效利用在蓄熱室1塔12及蓄熱室2塔14所蓄熱之排熱，必須在處理排出氣體一定時間之後切換排出氣體之流動的方向。亦即以蓄熱室1塔12→燃燒室16→蓄熱室2塔14的順序而流動之排出氣體，必須切換供給風門18a、18b及排出風門20a、20b的開閉狀態，使其 以蓄熱室2塔14→燃燒室16→蓄熱室1塔12的順序流動。 Here, in the regenerative exhaust gas purification device 4, in order to effectively utilize the heat exhausted in the regenerator 1 tower 12 and the regenerator 2 tower 14, it is necessary to switch the direction in which the exhaust gas flows after processing the exhaust gas for a certain period of time. In other words, the exhaust gas flowing in the order of the regenerator 1 tower 12 →the combustion chamber 16→the regenerator 2 tower 14 must be switched between the opening and closing states of the supply dampers 18a and 18b and the discharge dampers 20a and 20b. The flow in the regenerator 2 tower 14 → the combustion chamber 16 → the regenerator 1 tower 12 flows.
排出氣體的流動方向之切換，亦可構成為不是根據處理時間來進行，而是根據使用設置在分叉導管42之溫度感測器60所測定之排氣入口溫度T1與設置在分叉導管44之溫度感測器62所測定之排氣出口溫度T2的差來進行。 The switching of the flow direction of the exhaust gas may be configured not to be performed according to the processing time, but to be disposed on the bifurcation conduit 44 according to the exhaust inlet temperature T1 measured by the temperature sensor 60 disposed at the bifurcation conduit 42. The difference between the exhaust outlet temperatures T2 measured by the temperature sensor 62 is performed.
供給風門18a、18b及排出風門20a、20b之切換，係依照以下程序進行。首先，使外氣引進風門38為打開狀態而引進外氣。 The switching of the supply dampers 18a and 18b and the discharge dampers 20a and 20b is performed in accordance with the following procedure. First, the outside air is introduced into the damper 38 to be in an open state to introduce outside air.
其次，將熱旁通風門28及遮斷風門36設為關閉狀態，而使對吸附體6之脫附用空氣的供給中斷。接著，在將供給風門18a及排出風門20b關閉之同時，將供給風門18b及排出風門20a打開而切換氣體的流通方向。 Next, the hot side vent door 28 and the damper damper 36 are closed, and the supply of the desorbing air to the absorbing body 6 is interrupted. Next, while the supply damper 18a and the discharge damper 20b are closed, the supply damper 18b and the discharge damper 20a are opened to switch the flow direction of the gas.
切換完成之後，係使熱旁通風門28及遮斷風門36為打開狀態而再次再始對吸附體6之脫附用空氣的供給，且使外氣引進風門38為關閉狀態而停止外氣的引進。藉此，構成為排出空氣從打開狀態的供給風門18b經過蓄熱室2塔14流入燃燒室16而被燃燒除去可燃性有害成分，且已將可燃性有害成分除去且淨化後的氣體，係依序通過蓄熱室1塔12、打開狀態的排出風門20及分叉導管44而從排氣導管46排出。 After the completion of the switching, the hot side vent door 28 and the damper damper 36 are opened, and the supply of the desorbing air to the absorbing body 6 is again resumed, and the external air introducing damper 38 is closed and the outside air is stopped. Introduced. Thereby, the exhaust air is configured to flow from the supply damper 18b in the open state to the combustion chamber 16 through the regenerator 2 tower 14, and is burned to remove flammable harmful components, and the flammable harmful components are removed and purified. The regenerator 1 tower 12, the discharge damper 20 in the open state, and the branch conduit 44 are discharged from the exhaust duct 46.
從供給風門18a及排出風門20b為關閉狀態、供給風門18b及排出風門20a為打開狀態切換成為供給風門18a及排出風門20b為打開狀態、供給風門18b及排出風門20a為關閉狀態時亦是同樣的程序。 The same applies to the case where the supply damper 18a and the discharge damper 20b are in the closed state, the supply damper 18b, and the discharge damper 20a are in the open state, and the supply damper 18a and the discharge damper 20b are opened, and the supply damper 18b and the discharge damper 20a are closed. program.
如此，因為使供給風門18a、18b及排出風門20a、 20b連動而開閉，且在進行切換之際，可在供給風門18a、18b及排出風門20a、20b同時為打開狀態時，將遮斷風門36設為關閉狀態而使對吸附體6之脫附用空氣的供給中斷，並且使外氣引進風門38為打開狀態而引進不含有可燃性有害成分的外氣，而使所導入的氣通過打開狀態的供給風門18a、18b及排出風門20a、20b各者，所以能夠防止含有可燃性有害成分的排出空氣在還未將其可燃性有害成分燃燒除去時就被排出至大氣中。又，能夠藉由簡單的構造及較少的操作而迅速進行供給風門18a、18b及排出風門20a、20b的切換。 Thus, since the supply dampers 18a and 18b and the discharge damper 20a are provided, 20b is opened and closed in conjunction with each other, and when the supply dampers 18a and 18b and the discharge dampers 20a and 20b are simultaneously opened, the damper 36 can be closed and the detaching body 6 can be detached. The supply of air is interrupted, and the outside air is introduced into the damper 38 to open the state, and the outside air containing no flammable harmful component is introduced, and the introduced gas passes through the open supply dampers 18a and 18b and the exhaust dampers 20a and 20b. Therefore, it is possible to prevent the exhaust air containing flammable harmful components from being discharged to the atmosphere when the flammable harmful components have not been burned and removed. Moreover, the switching of the supply dampers 18a and 18b and the discharge dampers 20a and 20b can be quickly performed by a simple structure and a small operation.
又，亦能夠在不使熱旁通風門28為關閉狀態下，使供給風門18a、18b及排出風門20a、20b連動而開閉來進行切換。 Further, the supply dampers 18a and 18b and the discharge dampers 20a and 20b can be opened and closed in conjunction with the hot side vent door 28 without being closed.
在使用濃度計54測定在排出空氣之可燃性有害成分之濃度，且所測定的濃度為預先設定的濃度以上時，能夠調節外氣引進風門38的開度而將外氣供給至排出空氣來將可燃性有害成分稀釋。藉此，在蓄熱式排氣淨化裝置4，能夠防止排出空氣的可燃性有害成分之濃度太高而發生***的情形。 When the concentration of the flammable harmful component of the exhaust air is measured by the concentration meter 54 and the measured concentration is equal to or higher than a predetermined concentration, the opening degree of the external air introducing damper 38 can be adjusted to supply the external air to the exhaust air. Dilute flammable hazardous ingredients. Thereby, in the regenerative exhaust gas purification device 4, it is possible to prevent the concentration of the flammable harmful component of the discharged air from being too high to cause an explosion.
依照上述本發明的實施形態之排氣淨化設備1及該排氣淨化設備1的運轉控制方法，在進行複數組風門亦即供給風門18a、18b及排出風門20a、20b的開閉之切換之際，因為可於切換對象之風門同時為打開狀態時，使外氣引進風門38為打開狀態而引進外氣，且將遮斷風門36設為關閉狀態而使對吸附體供給之高溫脫附用空氣中斷並且使所導入的外氣通過打開狀態的風門各者，所以能夠防止含有可燃性有害成分的排出空氣在還未將其可燃性有害成分燃燒除去時就被排出至大氣中的情形。 According to the exhaust gas purification device 1 of the embodiment of the present invention and the operation control method of the exhaust gas purification device 1, when switching the opening and closing of the plurality of dampers, that is, the supply dampers 18a and 18b and the discharge dampers 20a and 20b, When the damper of the switching object is simultaneously opened, the outside air is introduced into the damper 38 to be in an open state, and the outside air is introduced, and the damper 36 is set to be in a closed state, so that the high temperature desorption air supplied to the absorbing body is interrupted. Further, since the introduced outside air passes through each of the dampers in the open state, it is possible to prevent the exhaust air containing the combustible harmful component from being discharged to the atmosphere when the combustible harmful component has not been burned and removed.
其次，參照第3圖而說明依照本發明實施形態的變形例之排氣淨化設備及其運轉控制方法。 Next, an exhaust gas purifying apparatus and an operation control method thereof according to a modification of the embodiment of the present invention will be described with reference to Fig. 3 .
依照上述實施形態之排氣淨化設備，係在蓄熱式排氣淨化裝置具有4個以上的偶數個蓄熱室時亦能夠應用。在此，具備偶數個蓄熱室之蓄熱式排氣淨化裝置，係為未具備用以進行沖洗的蓄熱室之構造。 The exhaust gas purification device according to the above embodiment can also be applied when the regenerative exhaust gas purification device has four or more even regenerators. Here, the regenerative exhaust gas purification device including an even number of regenerators has a structure in which a regenerator for rinsing is not provided.
如第3圖所顯示，依照該變形例之蓄熱式排氣淨化裝置係具備：4個之蓄熱室1塔70、蓄熱室2塔72、蓄熱室3塔74及蓄熱室4塔76。在該蓄熱式排氣淨化裝置中，係如以下進行風門的切換。又，蓄熱室3塔74及蓄熱室4塔76係與蓄熱室1塔70及蓄熱室2塔72同樣的構造，各自具備供給風門18c、排出風門20c及溫度感測器78與供給風門18d、排出風門20d及溫度感測器80。 As shown in Fig. 3, the regenerative exhaust gas purification apparatus according to this modification includes four regenerators 1 tower 70, a regenerator 2 tower 72, a regenerator 3 tower 74, and a regenerator 4 tower 76. In this regenerative exhaust gas purification apparatus, the damper is switched as follows. Further, the regenerator 3 tower 74 and the regenerator 4 tower 76 have the same structure as the regenerator 1 tower 70 and the regenerator 2 tower 72, and each includes a supply damper 18c, a discharge damper 20c, a temperature sensor 78, and a supply damper 18d. The damper 20d and the temperature sensor 80 are discharged.
在此，只顯示打開狀態的風門，其餘的風門係設為關閉狀態。 Here, only the damper in the open state is displayed, and the remaining dampers are set to the closed state.
(A)打開狀態：供給風門18a、18b、排出風門20c、20d (A) Open state: supply dampers 18a, 18b, exhaust dampers 20c, 20d
氣體的流動：蓄熱室1塔70、蓄熱室2塔72→燃燒室16→蓄熱室3塔74、蓄熱室4塔76 Flow of gas: regenerator 1 tower 70, regenerator 2 tower 72 → combustion chamber 16 → regenerator chamber 3 tower 74, regenerator chamber 4 tower 76
(B)打開狀態：供給風門18b、18c、排出風門20a、20d (B) Open state: supply dampers 18b, 18c, exhaust dampers 20a, 20d
氣體的流動：蓄熱室2塔72、蓄熱室3塔74→燃燒室16→蓄熱室1塔70、蓄熱室4塔76 Flow of gas: regenerator 2 tower 72, regenerator 3 tower 74 → combustion chamber 16 → regenerator chamber 1 tower 70, regenerator chamber 4 tower 76
(C)打開狀態：供給風門18c、18d、排出風門20a、20b (C) Open state: supply dampers 18c, 18d, exhaust dampers 20a, 20b
氣體的流動：蓄熱室3塔74、蓄熱室4塔76→燃燒室16→蓄熱室1塔70、蓄熱室2塔72 Flow of gas: regenerator 3 tower 74, regenerator 4 tower 76→combustion chamber 16→ regenerator chamber 1 tower 70, regenerator chamber 2 tower 72

如此，在具備偶數個蓄熱室之蓄熱式排氣淨化裝置中，即便未設置用以進行沖洗之蓄熱室，仍然能夠防止含有可燃性有害成分的排出空氣在還未將其可燃性有害成分燃燒除去時就被排出至大氣中的情形。藉此，能夠使排氣淨化設備更小型化。又，因為能夠縮小燃燒室，所以能夠削減用以維持溫度之燃料。 As described above, in the regenerative exhaust gas purification apparatus having an even number of regenerators, even if the regenerator for rinsing is not provided, it is possible to prevent the exhaust air containing combustible harmful components from burning off the combustible harmful components. It is then discharged to the atmosphere. Thereby, the exhaust gas purification device can be further miniaturized. Moreover, since the combustion chamber can be reduced, the fuel for maintaining the temperature can be reduced.
其次，藉由第4圖來說明依照本發明其他實施形態之排氣淨化設備。因為該其他實施形態之排氣淨化設備的基本構造，係與在第1圖所顯示之依照本發明實施形態之排氣淨化設備相同，故相同部分係附加相同符號而省略其說明。以下，主要就不同部分進行說明。 Next, an exhaust gas purifying apparatus according to another embodiment of the present invention will be described with reference to Fig. 4. The basic structure of the exhaust gas purification apparatus of the other embodiment is the same as that of the exhaust gas purification apparatus according to the embodiment of the present invention shown in Fig. 1, and the same portions are denoted by the same reference numerals, and the description thereof will be omitted. In the following, the main parts will be explained.
依照本發明其他實施形態之排氣淨化設備80，係不具有連續式再生式濃縮裝置而具有蓄熱式排氣淨化裝置4。因此，排氣淨化設備80係構成為，從各種生產設備或處理設備等上游側設備(未圖示)排出的含有可燃性有害成分的排氣，係直接被排出至排出導管34，經過該排出導管34而被供給至蓄熱式排氣淨化裝置4。 The exhaust gas purification device 80 according to another embodiment of the present invention has a regenerative exhaust gas purification device 4 without a continuous regenerative concentration device. Therefore, the exhaust gas purification device 80 is configured such that exhaust gas containing combustible harmful components discharged from upstream equipment (not shown) such as various production equipment or processing equipment is directly discharged to the discharge duct 34 through which the exhaust gas is discharged. The duct 34 is supplied to the regenerative exhaust gas purification device 4.
在排出導管34的遮斷風門36之上游側，係設置有將排氣暫時積存之積存槽82，在該積存槽82係安裝有開閉閥84。該開閉閥84係通常被保持在關閉狀態。 On the upstream side of the damper damper 36 of the discharge duct 34, a storage tank 82 for temporarily storing the exhaust gas is provided, and an opening and closing valve 84 is attached to the storage tank 82. The on-off valve 84 is normally kept in a closed state.
排氣淨化設備80亦與第1圖的實施形態之設備同樣地構成為，在供給風門18a、18b及排出風門20a、20b同時為打開狀態時，係使外氣引進風門38為打開狀態而將外氣引進排出導管 34內，且將遮斷風門36設為關閉狀態而使來自上游側設備的排氣不會被供給至蓄熱式排氣淨化裝置4。藉此，構成為被引進的外氣係通過打開狀態的供給風門18a、18b及排出風門20a、20b。 Similarly to the apparatus of the embodiment of Fig. 1, the exhaust gas purification device 80 is configured such that when the supply dampers 18a and 18b and the discharge dampers 20a and 20b are simultaneously opened, the external air introduction damper 38 is opened. External air introduction and discharge conduit In the 34, the shutoff damper 36 is set to the closed state, so that the exhaust gas from the upstream side device is not supplied to the regenerative exhaust gas purification device 4. Thereby, the introduced external air system is configured to pass the supply dampers 18a and 18b and the discharge dampers 20a and 20b in an open state.
此時，藉由使積存槽82為打開狀態，以使來自上游側設備的排氣暫時積存在積存槽82。其結果，在本實施形態之排氣淨化設備80中，即便在風門全部為打開狀態時，亦沒有暫停上游側設備的運轉等之必要。 At this time, the exhaust gas from the upstream side device is temporarily accumulated in the storage tank 82 by opening the storage tank 82. As a result, in the exhaust gas purification device 80 of the present embodiment, even when the damper is all open, there is no need to suspend the operation of the upstream device or the like.
依照本實施形態之排氣淨化裝置80，即便未設置連續式再生式濃縮裝置時，因為能夠將從上游側設備排出之含有可燃性有害成分的排氣暫時積存在積存槽82，所以在風門同時打開狀態時，不會有含有可燃性有害成分的排氣在還未將其可燃性有害成分燃燒除去時就被排出至大氣中之情形。 According to the exhaust gas purification device 80 of the present embodiment, even if the continuous regenerative concentration device is not provided, since the exhaust gas containing the combustible harmful component discharged from the upstream device can be temporarily accumulated in the storage tank 82, the damper is simultaneously In the open state, there is no possibility that the exhaust gas containing the flammable harmful component is discharged to the atmosphere when the flammable harmful component has not been burned and removed.
