Description

JOC reduction device and control method {DEVICE FOR REDUCING VOC AND CONTROL METHOD THEREOF}

The present invention relates to a VOC abatement apparatus and a control method thereof, and more particularly, to a VOC abatement apparatus and a control method thereof capable of improving driving conditions of a module for injecting a extinguishing agent in the process of processing VOC of indoor air.

In general, a large amount of VOCs are generated due to the development of the semiconductor and LCD industries due to the chemicals used in the manufacture of wafers and LCD panels, and a VOC treatment rotor is employed to process such VOCs.

VOCs may be present in the liquid or solid phase at room temperature and pressure, but can be defined as any organic compound present in the gas phase in the atmosphere. It is used to refer to all organic materials that can exist in the gaseous state at room temperature and atmospheric pressure, such as hydrocarbons composed of carbon and hydrogen only, halogenated hydrocarbons, nitrogen or sulfur-containing hydrocarbons, and also broadly include semi-volatile organic compounds.

The VOC treatment rotor passes the gas containing the organic solvent between the end faces of the rotatable VOC treatment rotor made of the adsorption element to adsorb the organic solvent to the adsorption element, and blows off the organic solvent attached to the adsorption element in a reverse direction by blowing hot air. It is also a device for purifying by blowing and blowing to restore the adsorption element to a reusable state.

In particular, a rotary type adsorber for organic solvents equipped with a conventional adsorption element rotates a VOC treated rotor in a holding case divided into an adsorption zone, a cooling zone, and a regeneration zone, whereby one end surface of the VOC treated rotor is rotated. The adsorption zone and regeneration zone are temporarily set in the air, and when the surface of the VOC treated rotor passes through the adsorption zone, the organic solvent is adsorbed by the adsorption element which supported the gas containing the organic solvent in the VOC treated rotor, and the organic solvent in the cooling zone. The adsorbed organic solvent is removed by passing the regeneration air heated to a temperature above the boiling point temperature of 180 ° C. to 200 ° C. through the inside of the adsorption element from the end face opposite to the above end face.

Among the gases containing an organic solvent, for example, gases generated in a semiconductor component manufacturing process or the like are, for example, DMSO (dimethylsulfoxide), MEA (monoethanol amine), HMDS (hexamethylene disilazane), or the like. Contains organic compounds. These organic compounds cannot be removed sufficiently at a regeneration temperature of 180 ° C to 200 ° C. For this reason, such organic compounds only accumulate in the VOC-treated rotor, causing deterioration of performance and the loss of the VOC-treated rotor. In order to remove such organic compounds, high temperature air heated to 200 to 350 ° C. must be sent from the regeneration zone to the VOC treatment rotor.

2 is a schematic view of the structure of the VOC abatement apparatus according to the present invention.

According to this figure, the VOC reduction apparatus 100 according to the present embodiment includes a body 110, a first damper 120 for processing, a second damper 130 for processing, a first damper 140 for regeneration, and a VOC.

The body 110 is connected to communicate with a clean zone such as a clean room while the first damper 120 and the second damper 130 are disposed on both sidewalls, respectively. The outside air inlet 112 having the first damper 140 and the regeneration air discharge port 114 communicating with the regeneration air discharge passage 116 are formed at the other end of the upper surface. At this time, the outside air inlet 112 may be provided with a processing fan (not shown in the drawing) forcibly introducing the outside air.

In addition, a plurality of processing fans 122 for forcibly introducing outside air may be provided on the side of the first damper 120 for processing, which is the inlet direction of the body 110. do. On the other hand, when some of the three processing fan 122 is broken by an electrical or mechanical defect, the three operating the fan by increasing the number of rotation of the remaining processing fan 122 by the control of the VOC reduction device controller 210 It can be made equal to the air volume of the case.

At this time, in the body 110, the treatment air is forcibly transferred to the adsorption zone 156 of the VOC treatment rotor 150 by the treatment fan 122, and the treated air is processed through the adsorption zone 156. Thereafter, the processing air exiting the adsorption zone 156 is cooled by the cooling coil 118 and then supplied to a clean zone of the target space. Here, the cooling coil 118 may be omitted.

The first damper 120 for processing is provided at the inlet side of the body 110 into which outside air is introduced to open and close the inlet side of the body 110 according to whether the extinguishing agent injection module 200 to be described later is operated. It is opened at the inflow of outside air and closed at the time of emergency such as fire.

The second damper 130 for treatment is provided at the outlet side of the body 110 through which the treatment air is discharged, and opens and closes the outlet side of the body 110 according to whether the extinguishing agent injection module 200 to be described later is operated. It is open when inflow of outside air and closed in case of emergency such as fire.

Here, the treatment first damper 120 and the treatment second damper 130 are closed in an emergency such as a fire to prevent the extinguishing agent from being discharged to the outside.

Regeneration first damper 140 is installed in the outside air inlet 112 of the body 110 to open and close the outside air inlet 112 of the body 110 according to the operation of the extinguishing agent injection module 200 to be described later. It is opened at the inflow of outside air and closed at the time of emergency such as fire.

The VOC-treated rotor 150 is a continuously arranged along the rotational direction of the rotor by using an adsorbent layer using an adsorbent such as silica gel, zeolite, activated carbon, etc. as a component, and in the direction along the rotation axis. The cylindrical shape which can pass a gas is adopted.

At this time, the VOC processing rotor 150 is made of a honeycomb-like processing material, and further includes a rotation driving unit (not shown in the drawing) for rotating the processing rotor.

Furthermore, the VOC processing rotor 150 is divided into a cooling zone 152, a regeneration zone 154, and an adsorption zone 156 in the rotational direction, and these three zones are arranged in the order described above. As a result, when the VOC (Volatile Organic Compounds) is treated with the rotation of the processing rotor, the respective parts are transferred in the order of the regeneration zone 154, the cooling zone 152, and the adsorption zone 156.

The reheating heating coil 160 is provided in plural and functions to heat the air treated in the cooling zone 152 of the VOC processing rotor 150 before supplying it to the regeneration zone 154. In this embodiment, Illustrates that a dog is installed. Here, the reason why the plurality of reheating heating coils 160 are provided is that dividing the heating temperature into two rather than controlling the entire heating temperature by one may reduce the operating load.

The temperature sensor 170 includes a plurality of first temperature sensors TE1, second temperature sensors TE2, third temperature sensors TE3, and third between the regenerative heating coil 160 and the VOC processing rotor 150. 4, a temperature sensor TE4 is provided in the direction from the regenerative heating coil 160 to the VOC processing rotor 150 to sense the ambient temperature of the regenerative heating coil 160 and onto the regenerative air discharge passage 116. The fifth temperature sensor TE5 is provided to sense the temperature of the regenerated air exhausted.

The first temperature sensor TE1, the second temperature sensor TE2, the third temperature sensor TE3, the fourth temperature sensor TE4, and the fifth temperature sensor TE5 are each a VOC reduction device controller 210. ) Is electrically connected to the sensor to transmit sensing values. The first temperature, the second temperature, the first temperature sensor TE1, the second temperature sensor TE2, the third temperature sensor TE3, the fourth temperature sensor TE4, and the fifth temperature sensor TE5 may be used. The third temperature, the fourth temperature, the fifth temperature, the sixth temperature, and the seventh temperature can be detected.

The first temperature sensor TE1 simultaneously detects the first temperature and the sixth temperature, which are the temperatures of the before and after reheating heating coil 160, and the second temperature sensor TE2 simultaneously detects the second temperature and the alarm temperature. The third temperature sensor TE3 detects a fire alarm temperature which is a third temperature, the fourth temperature sensor TE4 detects a fire alarm temperature which is a fourth temperature, and the fifth temperature sensor TE5 is a regeneration air discharge passage. The exhaust temperature, which is the fifth temperature emitted from 116, is always sensed. And the seventh temperature is the stop temperature of the regeneration fan P.

Here, as an example, if the range of each temperature is limited, the first temperature range is 230 to 250 ° C, the second temperature range is 250 to 300 ° C, the third temperature range is 240 to 260 ° C, and the fourth temperature range is It is 280-300 degreeC, the 5th temperature range is 40-60 degreeC, the 6th temperature range is 190-210 degreeC, and the 7th temperature range is 40-60 degreeC.

That is, the first temperature sensor TE1 is a heating coil for regeneration through a magnetic circuit MC controlled by the VOC reduction device controller 210 to turn on / off driving when the sensing temperature value is greater than the first temperature. The operation 160 is stopped, and when the sensing temperature value is less than the sixth temperature, the heating coil 160 for regeneration is operated through a magnetic circuit controlled by the VOC reduction device controller 210 to turn on / off the driving. This means that the first temperature sensor TE1 detects an upper limit value and a lower limit value according to the temperature of the front and rear regeneration heating coil 160.

As a result, the first temperature sensor TE1 stops the operation of the regenerative heating coil 160 when the sensing temperature is greater than the first temperature, and activates the regenerative heating coil 160 when the sensing temperature is smaller than the sixth temperature. It is.

The second temperature sensor TE2 provides a fire alarm signal to the VOC reduction device controller 210 when the VOC reduction device 100 maintains a normal operating state and the sensing temperature value is greater than the second temperature. If less than the second temperature is provided to the VOC abatement controller 210 to output a fire monitoring normal indication to the VOC abatement controller 210.

The third temperature sensor TE3 is configured to maintain a normal operating state of the VOC reducing device 100 like the second temperature sensor TE2, but when the sensing temperature value is greater than the third temperature, the third temperature sensor TE3 transmits a fire alarm signal to the VOC reducing device controller 210. If the sensing temperature value is less than the third temperature is provided to the VOC reduction device controller 210 to output a fire monitoring normal indication.

The fourth temperature sensor TE4 may operate the regeneration fan P when the sensing temperature value is lower than the seventh temperature while the regeneration heating coil 160 and the first, second and third processing fans 122 are turned off. It is provided to the VOC reduction device controller 210 to be turned off. Thereafter, the regeneration first damper 140 and the regeneration second damper 180 and the regeneration third damper 190 are closed after the set time, and the VOC reduction device 100 is stopped.

The fifth temperature sensor TE5 may generate an alarm signal when the sensing temperature value is less than the fifth temperature when the sensing temperature value is less than the first temperature in the first temperature sensor TE1. After providing to the processing fan 122 is turned on all, if the sensing temperature value is greater than the fifth temperature is provided to the VOC reduction device controller 210 so that all of the processing fan 122 can be turned on immediately.

On the other hand, when sensing the temperature using one temperature sensor 170, when electrical or mechanical defects occur in the sensor, the injection timing of the extinguishing agent is missed by the sensing error. In addition, when the sensing temperature is higher than the actual temperature of the actual temperature sensor 170 due to the failure of the temperature sensor 170, there is a problem that the injection of the extinguishing agent should not be sprayed.

As a result, as described above, when the temperature rise due to a flame or the like, the fire extinguishing agent should be sprayed, but the temperature is sensed to be low due to a sensor defect, and the fire extinguishing agent should not be sprayed. There is a need for a solution for the injection of extinguishing agents.

In order to solve such a problem, in the present invention, the sensing temperature of the reheating heating coil 160 includes a plurality of temperature sensors 170 including the first temperature sensor TE1, the second temperature sensor TE2, and the third temperature sensor TE3. ) And a fourth temperature sensor TE4 to detect all of the temperature detection values of the plurality of temperature sensors 170 exceed a set value, or sense a temperature of a portion of the plurality of temperature sensors 170. If the set value is satisfied, such as when the value exceeds the set value, it is controlled to spray the extinguishing agent. As a result, if the deviation is within the set value by putting a deviation in the temperature sensed by the plurality of temperature sensors 170, it is normal, if it is above the set value it can be recognized that there is an error in the sensor.

The second damper for regeneration 180 is provided in the middle of the lower end of the regeneration air discharge passage 116 communicating with the outside air inlet 112 of the body 110, and the regeneration according to whether the extinguishing agent injection module 200 will be described later. The air discharge passage 116 is opened and closed, and is opened when the outside air is introduced, and is closed in an emergency such as a fire.

The third damper 190 for regeneration is provided at the upper end of the regenerated air discharge passage 116 that is upper side of the second damper 180 for regeneration, and discharges the regenerated air according to whether the extinguishing agent injection module 200 to be described below is operated. The passage 116 is opened and closed, and is opened when the outside air is introduced, and is closed in an emergency such as a fire. In addition, the third damper 190 for regeneration is always set to an open state, and in case of an emergency fire, the third damper 190 receives power from the controller 220 for disaster prevention means and is set to operate rapidly in a closed state.

Furthermore, the third damper 190 for regeneration is opened when the regeneration fan P disposed in communication with the regeneration air outlet 114 of the body 110 is closed and closed when the regeneration fan P is stopped. Controlled through the VOC abatement controller 210.

Here, the regeneration first damper 170 and the regeneration second damper 180 are closed in an emergency such as a fire to prevent the extinguishing agent from being discharged to the outside as in the first and second dampers for treatment.

Fire extinguishing agent injection module 200 detects the ambient temperature of the heating coil 160 for regeneration in a plurality of temperature sensors 170, all of the plurality of temperature sensors exceeds a set value, or a plurality of temperature sensors 170 If some of the setting value exceeds the set value VOC reduction device controller 210 to send the operation signal to the controller 220 for disaster prevention means to inject the extinguishing agent. In another embodiment, the extinguishing agent injection module 200 is configured to regenerate the heating coil 160 for regeneration in the first temperature sensor TE1, the second temperature sensor TE2, the third temperature sensor TE3, and the fourth temperature sensor TE4. By sensing the ambient temperature, the fire extinguishing agent is sprayed by sending an operation signal from the VOC reduction device controller 210 to the controller 220 for disaster prevention means according to the amount of temperature deviation. At this time, the extinguishing agent injection module 200 includes a extinguishing agent accommodating part 202, a extinguishing agent injecting part 204, a piston 206, and the like.

Here, the valve (V) is provided with a solenoid (solenoid (not shown in the figure)) to operate the valve (V) while the solenoid is operated by the signal of the controller 220 for disaster prevention means.

The extinguishing agent spraying unit 204 is in communication with the extinguishing agent receiving unit 202 through a pipe or a tube, etc., and extinguishing agent contained in the extinguishing agent receiving unit 202 is injected when an operation signal of the controller 220 for disaster prevention means is output. The components are located close to the cooling zone 152, the regeneration zone 154 and the adsorption zone 156 in the interior of the body 110.

Piston 206 is in communication with the extinguishing agent receiving unit 202 through a pipe or tube, etc., when the extinguishing agent contained in the extinguishing agent receiving unit 202 is output when the operation signal of the controller 220 for disaster prevention means is extinguishing agent injection unit The first damper 120 for treatment, the second damper 130 for treatment and the first damper 140 for regeneration, the second damper 180 for regeneration, and the regenerating agent through the injection pressure at the same time at 204. 3 provides a driving force to selectively drive the damper 190.

In other words, the extinguishing agent spray module 200 is a fire extinguishing agent in the extinguishing agent injection unit 204 and the piston in the extinguishing agent receiving unit 202 with a pump or the like when the operation signal is output from the controller 220 for disaster prevention means Simultaneously conveyed toward the side 206, the extinguishing agent is injected from the extinguishing agent injection unit 204 and at the same time to advance the rod of the piston 206 by the injection pressure of the extinguishing agent and the first damper 120 for treatment, treatment agent The second damper 130, the first damper for regeneration 140, the second damper for regeneration 180, and the third damper for regeneration 190 may be selectively operated to close a specific damper.

Meanwhile, when the extinguishing agent injection module 200 is operated, the first damper 120 for processing, the second damper 130 for processing, and the first damper 140 for regeneration through the control of the VOC reduction device controller 210. The second damper 180 for regeneration is closed earlier and the third damper 190 for regeneration is closed later. Thus, at least one of the first damper 120 for treatment, the second damper 130 for treatment, the first damper 140 for regeneration, and the second damper 180 for regeneration is first closed, and the third third for regeneration is performed. The damper 190 is closed later with a time difference to ensure safety in the process of spraying the extinguishing agent.

Whether the second damper 130 and the first damper 140 for regeneration, the second damper 180 for regeneration, and the third damper 190 for regeneration are opened and closed, the reheating heating coil 160 and the extinguishing agent injection The driving of the module 200 is controlled.

Disaster prevention means controller 220 is an auxiliary controller, and provides a drive signal to the extinguishing agent injection module 200 by the control of the VOC abatement controller 210 is electrically connected. Furthermore, the controller 220 for the disaster prevention means drives the fire extinguishing agent injection module 200, that is, the first damper 120 for treatment, the second damper 130 for treatment, and the first damper 140 for regeneration. In addition, a recognition module including a warning light or an alarm may be further provided to allow the operator to recognize the current situation visually or acoustically when the second damper 180 for regeneration and the third damper 190 for regeneration are closed. .

That is, when the VOC reduction device controller 210 outputs a drive signal to the disaster prevention means controller 220, the disaster prevention means controller 220 outputs a drive signal to the recognition module to drive the recognition module for a set time. After the extinguishing agent is injected through the extinguishing agent injection module 200, the first damper 120 for treatment, the second damper 130 for treatment, the first damper 140 for regeneration, and the second damper for regeneration ( After the 180 is closed and the regeneration fan P is stopped, the third damper 190 for regeneration is closed after a predetermined time.
