Description

Concentrate and 2-bed type regenerative thermal oxidizer with purge means

The present invention relates to a concentrated two-bed regenerative combustion device equipped with a purge means, and in particular, a purge means for discharging after reprocessing the gas discharged in a section in which the gas movement path is changed in the two-bed regenerative combustion device. The present invention relates to a concentrated two-bed regenerative combustion device having a purge means capable of increasing the decomposition efficiency of volatile organic compounds and operating like a three-bed regenerative combustion device without adding a bed.

Volatile Organic Compounds (VOCs) refer to hydrocarbon compounds that volatilize in the atmosphere and generate odors or ozone, and are carcinogens that cause disorders in the nervous system through skin contact or respiratory inhalation. These volatile organic compounds are collectively referred to as benzene, formaldehyde, toluene, xylene, ethylene, styrene, acetaldehyde, and the like.

In general, volatile organic compounds are removed and discharged using a regenerative combustion device in factories, etc. The heat storage type combustion device adopts a direct heat exchange method using a heat storage material, so it has high heat recovery efficiency and is an economical combustion device that can significantly reduce the amount of fuel.

The regenerative combustion device has two or more regenerative chambers and a combustion chamber in the center. That is, as the volatile organic compound passes through the heat storage chamber and is burned in the combustion chamber with an elevated temperature, the odorous material is burned and decomposed. In addition, the purified high-temperature gas passes through another heat storage chamber, loses heat, and is discharged to the atmosphere in a lowered state. The heat storage chamber in the direction in which the volatile organic compound flows and the purified gas flows out is changed at regular intervals. Through this operation, the volatile organic compound is removed.

There are two-bed type, three-bed type, etc. in the form of regenerative combustion device. The two-bed type thermal regenerative combustion device removes volatile organic compounds using two thermal regenerative beds. However, in order to switch the flow of the volatile organic compounds introduced therein, the damper must be opened and closed at the same time, and there is a problem in that the decomposition efficiency is lowered because some untreated gas is discharged at the moment the damper is opened and closed. In order to improve this, a three-bed type regenerative combustion device using three thermal storage beds is sometimes used by adding one thermal storage bed. Although the decomposition efficiency is improved, there is a problem in that the cost increases due to the addition of the thermal storage bed.

The problem to be solved by the present invention is to increase the decomposition efficiency of volatile organic compounds by providing a purge means for reprocessing and discharging the gas discharged in the section in which the gas movement path is changed in the two-bed regenerative combustion device. An object of the present invention is to provide a concentrated two-bed regenerative combustor equipped with a purge means capable of operating like a three-bed regenerative combustor without addition.

The first path control unit may change to a second path from a state in which the first path is set, or may change to the first path in a state in which the second path is set. The second route control unit performs the first path control unit in the first route control unit during a first section in which the first route changes from the first route to the second route or during a second section in which the second route changes to the first route. The exhaust gas may be controlled to be delivered to the concentrator, and the first route controller may control the combustion gas to be delivered to the outlet during a third section set as the first route or the second route.

The first path control unit includes a plurality of dampers for changing the moving direction of the enriched gas or the combustion gas to set the first path or the second path, the first section is one of the plurality of dampers starts the operation first, all of the plurality of dampers complete the operation from a point in time when the first path control unit first starts an operation among the plurality of dampers in order to change from the first path to the second path includes a section up to a point in time, and the second section is configured to change the first route from the second route to the first route by the first route control unit when one of the plurality of dampers starts to operate first. It may include a section from a time when an operation is first started among the plurality of dampers to a time when all of the operation of the plurality of dampers are completed.

In the first section, from a first time point that is earlier than a time point at which the first route control unit starts to operate to change from the first route to the second route, the first route control unit moves from the first route to the second route. It is a section up to a second time point that is later than the time point at which the change to the second route is completed, and the second section starts to operate in order for the first route control unit to change from the second route to the first route It may be a section from a third time point that is earlier than the time point to a fourth time point that is later than the time point at which the first route control unit completes the change from the second route to the first route.

The second path control unit includes a feedback damper for controlling the gas discharged from the first path control unit to be transmitted to the outlet or to the concentrator, and while the first path or the second path is set, the first path control unit The feedback damper is controlled so that the gas discharged from the path control unit is transferred to the outlet, and the first section is changed from the first path to the second path, or the second path is changed from the second path to the first path.

There is an advantage in that the decomposition efficiency of the volatile organic compound can be increased by having a purge means for processing and transferring it back to the regenerative combustion device after the transfer. In other words, in the case of a two-bed type regenerative combustion device, the path through which the volatile organic compound flows and the path through which the inflow volatile organic compound is combusted must be changed every a certain period of time. There was a problem in that the decomposition efficiency was lowered as unburned volatile organic compounds were discharged during the section in which the damper was operated. In order to solve this problem, the present invention uses a two-bed type regenerative combustion device by transferring the gas discharged from the section where the gas path is changed to the exhaust port, concentrating it, and then transferring it to the regenerative combustion device for processing. However, there is an advantage in that the decomposition efficiency can be increased, such as using a three-bed type regenerative combustion device. In addition, the concentrated two-bed regenerative combustion device provided with a purge means according to an embodiment according to the technical concept of the present invention obtains the same efficiency as a three-bed type regenerative combustion device and at a lower cost than a three-bed type regenerative combustion device Since a two-bed type regenerative combustion device that can be installed can be used, there is an advantage in that the installation cost and installation size can be greatly reduced.

Hereinafter, the present invention will be described in detail by describing preferred embodiments of the present invention with reference to the accompanying drawings. Like reference numerals in each figure indicate like elements.

1 is a view schematically showing a concentrated two-bed regenerative combustion device 100 having a purge means according to an embodiment according to the technical idea of the present invention. FIG. 2 is a view for explaining a case in which the concentrated two-bed regenerative combustion device 100 provided with the purge means of FIG. 1 operates in a state in which the first path is set, and FIG. It is a view for explaining a case in which the concentrated two-bed regenerative combustion device 100 is converted between the first path and the second path, and FIG. 4 is the concentrated two-bed regenerative combustion device 100 equipped with the purge means of FIG. ) is a diagram for explaining a case in which the second path operates in a set state.

1 to 4, the concentrated two-bed regenerative combustion device 100 provided with a purge means includes a concentrator 110, a regenerative combustion device 120, a first path control unit 130, and a second path control unit ( 140) may be provided. The concentrated two-bed regenerative combustion apparatus 100 provided with the purge means may employ a regenerative combustion method or a regenerative catalytic combustion method.

The concentrator 110 receives and purifies the volatile organic compound, and discharges the purified air to the outside through the outlet, and desorbs the adsorbed contaminants while the volatile organic compound is purified, thereby transferring the concentrated gas to a high concentration through the first path. It may be discharged to the control unit 130 . That is, the amount of fuel used in the regenerative combustion device 120 can be reduced by adsorbing the volatile organic compounds using the concentrator 110 and delivering the high concentration concentrated gas to the regenerative combustion device 120 to be described below. . Since the configuration of the concentrator 110 is the same as or similar to that of the concentrator having various structures generally used, a detailed description of the structure and operation of the concentrator 110 will be omitted below.

The regenerative combustion device 120 may include a first heat storage bed 123 and a second heat storage bed 125 that burn the concentrated gas to discharge the purified combustion gas, and are passages through which the combustion gas moves. The first heat storage bed 123 and the second heat storage bed 125 include heat storage materials, and a combustion chamber for burning the concentrated gas is formed on the first heat storage bed 123 and the second heat storage bed 125 . do. The regenerative combustion device 120 may be a Regenerative Thermal Oxidizer (RTO) to which a regenerative combustion method is applied, or a Regenerative Catalytic Oxidizer (RCO) to which a regenerative catalytic combustion method is applied. It may be another device to which the method is applied.

When the concentrated gas moves through the first heat storage bed 123 or the second heat storage bed 125, the heat stored in the first heat storage bed 123 or the second heat storage bed 125 is transferred to the concentrated gas. Thus, the temperature of the concentrated gas is increased. Therefore, it is possible to minimize fuel consumption in burning the enriched gas in the combustion chamber. And since the combustion gas burned in the combustion chamber is high temperature, the combustion gas moves through the first heat storage bed 123 or the second heat storage bed 125 and the first heat storage bed 123 or the second heat storage bed 125. As the heat of the combustion gas is taken away, the temperature of the combustion gas is lowered and the temperature of the first heat storage bed 123 or the second heat storage bed 125 is increased. While this operation is repeated, in order to obtain the same effect as described above, the movement path of the enriched gas and the movement path of the combustion gas must be changed at a predetermined time interval. Hereinafter, a case in which the movement path of the enriched gas and the combustion gas is changed will be described.

The first path control unit 130 may set a first path so that the concentrated gas discharged from the concentrator 110 is transferred to the first heat storage bed 123 and the combustion gas is discharged from the second heat storage bed 125 . Alternatively, the first path control unit 130 may set a second path so that the concentrated gas discharged from the concentrator 110 is transferred to the second heat storage bed 125 and the combustion gas is discharged from the first heat storage bed 123 . have. In addition, the first path control unit 130 may change to the second path in a state in which the first path is set, or may change to the first path in a state in which the second path is set. The first path control unit 130 may include at least one damper for changing the moving direction of the enriched gas or the combustion gas to set the first path or the second path, and the first path control unit 130 . Embodiments including the damper will be described in more detail with reference to FIGS. 5 to 7 .

The second path control unit 140 may be a purge means for performing a purge function by controlling the gas discharged from the first path control unit 130 to be delivered to the outlet or to the concentrator 110 . The outlet may be an outlet of the concentrated two-bed regenerative combustion device 100 equipped with a purge means, or may be connected to a chimney or the like. The second path control unit 140 may include a feedback damper for controlling the gas discharged from the first path control unit 130 to be transmitted to the outlet or to the concentrator 110 , and the second path control unit 140 may Embodiments including the feedback damper will be described in more detail with reference to FIGS. 5 to 7 .

More specifically, the second route control unit 140 is configured to include a first section in which the first route control unit 130 changes from the first route to the second route or a second route in which the second route changes to the first route. During the section, the gas discharged from the first path control unit 130 is controlled to be delivered to the concentrator 110, and during the third section in which the first path control unit 130 is set as the first path or the second path, the It is possible to control the combustion gas to be delivered to the outlet. That is, the second path control unit 140 transfers the gas delivered from the first path control unit 130 to the concentrator 110 during the first section or the second section, which is a section in which the first path control unit 130 changes the path. After concentration, the reprocessing may be performed by allowing it to flow into the regenerative combustion device 120 again. The first path control unit 130 blocks the flow path (pipe) through which the concentrated gas is delivered to the first heat storage bed 123 and opens the flow path (pipe) through which the concentrated gas is delivered to the second heat storage bed 125 . may change the first path to the second path through Alternatively, on the contrary, the first path control unit 130 blocks the flow path (pipe) through which the concentrated gas is delivered to the second heat storage bed 125 and the flow path (pipe) through which the concentrated gas is delivered to the first heat storage bed 123 . Through the opening operation, the second path may be changed to the first path. However, when the flow path is changed in this way, there is a problem that the concentrated gas that has not been processed during the time for changing the flow path is discharged from the first path control unit 130 . The untreated concentrated gas discharged as described above is mixed with the combustion gas in which the volatile organic compounds have been decomposed, and thus the decomposition efficiency of the volatile organic compounds is lowered. Therefore, in the present invention, the gas discharged from the first route control unit 130 during the first section in which the first route is changed to the second route or the second section in which the second route is changed to the first route is the outlet. There is an advantage in that the decomposition efficiency is lowered in the two-bed type regenerative combustion device by feeding it back to the concentrator 110 instead of transferring it to the concentrator 110 .

In the above description, the first section is from a first time point that is earlier than a time point at which the first route control unit 130 starts to operate to change from the first route to the second route. ) may be a section from the first route to the second time point that is later than the time point at which the change from the first route to the second route is completed. And in the second section, the first route control unit 130 performs the first route control unit 130 from a third time point that is earlier than the time point at which the first route control unit 130 starts to operate to change from the second route to the first route. It may be a section from the second path to the fourth time point later than the time when the change from the second route to the first route is completed. That is, in order to precisely match the starting and ending times of the path change by the first path control unit 130 and the timing at which the second path control unit 140 controls the gas to be delivered to the concentrator 110, very precise control is required. Therefore, in the present invention, the first time point from the first time point before the time point at which the first route control unit 130 starts to change the route to the second time point after the completion point for completing the route change is the first time point. It can be set as a section. Therefore, the second path control unit 140 controls the gas flowing out from the first path control unit 130 from a time before the time when the first path control unit 130 starts to change the path to a time later than the time at which the path change is completed. By transferring to the concentrator 110, it is possible to maximize the decomposition efficiency of the volatile organic compound.

Referring to the operation of the concentrated two-bed regenerative combustion device 100 having a purge means with reference to FIGS. 2 to 4 , when the first path control unit 130 sets the first path as shown in FIG. 2 , The concentrated gas transferred from the concentrator 110 to the regenerative combustion device 120 is transferred to the combustion chamber through the first regenerative bed 123 to receive heat from the first regenerative bed 123 . As described above, the concentrated gas, which has received heat and has become a high temperature, is burned in the combustion chamber and converted into a high temperature combustion gas. In addition, the high-temperature combustion gas is discharged to the outside of the regenerative combustion device 120 through the second heat storage bed 125 to lose heat to the second heat storage bed 125 . When this operation occurs for a predetermined time, the temperature of the first thermal storage bed 123 is lowered and the temperature of the second thermal storage bed 125 is increased, and as described above, the first thermal storage bed 123 is converted to the concentrated gas. A phenomenon occurs in which heat cannot be transmitted and the second heat storage bed 125 cannot receive heat from the combustion gas. Accordingly, after a predetermined time has elapsed or when the temperature of the thermal storage bed becomes above or below the threshold value, the first path control unit 130 changes the first path to the second path.

As shown in FIG. 3 , when the first path control unit 130 operates to change from the first path to the second path, the first path control unit 130 changes the first path from the first path to the second path. A portion of the enriched gas that is not purified through the first path control unit 130 during one section may be discharged. Therefore, during the first section, the second path control unit 140 transmits the gas discharged from the first path control unit 130 to the concentrator 110 without transferring the gas to the outlet. The concentrator 110 mixes and concentrates the gas received through the second path control unit 140 and the flowing volatile organic compound, and then transmits it to the regenerative combustion device 120 , so that the concentrator 110 in the second path control unit 140 . ), the delivered gas can be purified.

As shown in FIG. 4 , when the second path is stably maintained after the first section has elapsed, the concentrated gas discharged from the concentrator 110 is transferred to the combustion chamber through the second heat storage bed 125 and the second heat storage bed. Heat is transferred from (125). As described above, the concentrated gas, which has received heat and has become a high temperature, is burned in the combustion chamber and converted into a high temperature combustion gas. In addition, the high-temperature combustion gas is discharged to the outside of the regenerative combustion device 120 through the first heat storage bed 123 to lose heat to the first heat storage bed 123 . When this operation occurs for a certain period of time, the temperature of the second thermal storage bed 125 is lowered and the temperature of the first thermal storage bed 123 is increased. As described above, the second thermal storage bed 125 is converted to the concentrated gas. A phenomenon occurs in which heat cannot be transmitted and the first heat storage bed 123 cannot receive heat from the combustion gas. Therefore, after a certain time has elapsed or when the temperature of the thermal storage bed becomes above or below the threshold value, the first path control unit 130 changes the second path from the second path to the first path again.

As shown in FIG. 3 , when the first path control unit 130 operates to change from the second path to the first path, the first path control unit 130 changes the second path from the second path to the first path. During the second section, the concentrated gas that is not purified through the first path control unit 130 may be partially discharged. Accordingly, during the second section, the second path control unit 140 transmits the gas discharged from the first path control unit 130 to the concentrator 110 without transferring the gas to the outlet. The concentrator 110 mixes and concentrates the gas received through the second path control unit 140 and the flowing volatile organic compound, and then transmits it to the regenerative combustion device 120 , so that the concentrator 110 in the second path control unit 140 . ), the delivered gas can be purified. When the first route is stably maintained after the lapse of the second section, the same operation as described above is repeatedly performed while operating in the same state as in FIG. 2 again.

The concentrated two-bed regenerative combustion apparatus 100 with a purge means may further include a chamber 150 . The chamber 150 is coupled between the second path control unit 140 and the concentrator 110 , and includes a storage space in which the gas transferred from the second path control unit 140 to the concentrator 110 is stored, the storage space Some or all of the gas stored in may be delivered to the concentrator (110). That is, when the chamber 150 is not formed, all of the gas discharged from the second path control unit 140 during the first section or the second section is delivered to the concentrator 110 in real time. In addition, when the chamber 150 is formed, the gas discharged from the second path control unit 140 during the first section or the second section may be stored in the storage space of the chamber 150 . In addition, the chamber 150 may deliver all of the gas stored in real time to the concentrator 110 , store a certain amount of gas in the storage space, and then transfer some or all of the stored gas to the concentrator 110 , , it is also possible to adjust the amount or speed of the gas delivered to the concentrator (110).
