Generally, incinerators, metal melting furnaces, boilers, and wet desulfurization facilities, which are facilities for discharging air pollutants, discharge high temperature exhaust gas containing high-concentration contaminants to the atmosphere during operation.

Therefore, in order to remove contaminants contained in the exhaust gas, an absorption tower, which is a wet type dust collecting facility for removing harmful substances by spraying an aqueous solution, is installed and used.

Such wet dust collecting facilities spray water to the discharged high temperature exhaust gas, so that exhaust gas in a high temperature and high humidity condition is discharged to the atmosphere through the stack.

The waste heat recovery and white smoke reduction apparatus 100 may include an exhaust gas discharge unit 110, a heat and water exchange unit 120, and a circulation supply unit 130.

Here, the heat and moisture exchanging part 120 can be supplied with a high-temperature exhaust gas and water vapor, and a solution containing wet scrubbing salts can be supplied to lower the temperature of the exhaust gas.

The exhaust gas discharge unit 110 is connected to the heat and water exchange unit 120 to discharge the cooled exhaust gas to the outside.

Next, the circulation supply unit 130 is connected to the heat and water exchange unit 120 to concentrate and cool the solution contained in the hygroscopic salts to circulate the solution.

Here, the first measurement unit 210 may be arranged in the waste heat recovery and white smoke reduction apparatus 100, and in some cases, only some components may be disposed in the monitoring system 200.

For example, the temperature sensor and the humidity sensor of the first measurement unit 210 may be disposed in the waste heat recovery and white smoke reduction apparatus 100, and the data signal processing unit and the communication unit may be disposed in the monitoring system 200.

The plurality of temperature sensors or humidity sensors can be arranged at regular intervals from the inside of the exhaust gas discharging portion 110 to the outside adjacent to the outside atmosphere.

In other cases, the temperature sensor or the humidity sensor may be disposed so that the interval becomes gradually narrower from the inside of the exhaust gas discharging portion 110 to the outside atmosphere when the number of the temperature sensors or the humidity sensor is plural.

The reason is that the temperature and the humidity of the exhaust gas moving to the atmosphere are most important, so that more sensors are disposed in the vicinity of the atmosphere, thereby accurately measuring the temperature and humidity of the exhaust gas discharged into the atmosphere .

As another example, when the number of the temperature sensors and the humidity sensors is plural, they may be arranged alternately with each other.

The reason is that the arrangement of the temperature sensor and the humidity sensor is efficient and the temperature and humidity of the exhaust gas are measured in a balanced manner.

Next, the second measurement unit 220 can measure the hygroscopic salt concentration from the waste heat recovery and white smoke reduction apparatus 100.

The second measurement unit 220 may include at least one concentration sensor disposed in the heat and water exchange unit 120 of the waste heat recovery and white smoke reduction apparatus 100 to sense the hygroscopic salt concentration.

Here, the third measuring unit 230 may be arranged in the waste heat recovery and white smoke reducing apparatus 100, and in some cases, only some of the components may be disposed in the monitoring system 200.

For example, the concentration sensor of the third measurement unit 230 may be disposed in the waste heat recovery and white smoke reduction apparatus 100, and the data signal processing unit and the communication unit may be disposed in the monitoring system 200.

The notification message generating unit 240 generates a notification message based on the digital data signals measured by the first, second, and third measurement units 210, 220, and 230, And can generate a notification message about the operation status.

Next, the display unit 250 may display the digital data signals measured from the first, second, and third measurement units 210, 220, and 230, respectively.

The communication unit 260 may receive the digital data signals measured from the first, second, and third measurement units 210, 220, and 230 and may output the control signal of the control unit 270 as waste heat recovery and white smoke reduction Or may send a notification message to the administrator terminal 310 via a wired or wireless communication network such as the Internet.

The control unit 270 may include first, second and third measuring units 210, 220 and 230, a notification message generating unit 240, a display unit 250, and a communication unit 260 ) Can be selectively controlled.

The control unit 270 checks whether at least one of the temperature and the humidity of the exhaust gas measured by the first measuring unit 210 is greater than a preset reference value. If the temperature and the humidity are greater than the reference value, And transmits the notification message to the administrator terminal 310. It is checked whether the hygroscopic salt concentration measured by the second measurement unit 220 is within the reference range. If the hygroscopic salt concentration is within the reference range, It is possible to regenerate the notification message informing of the abnormal operation of the device 100 and to retransmit the message to the administrator terminal 310 or to stop the operation of the waste heat recovery and white smoke reduction device 100.

Also, the control unit 270 can control the first measuring unit 210 to measure the temperature and humidity of the exhaust gas at predetermined time intervals.

For example, when the control unit 270 receives the time setting request signal for measuring the temperature and humidity of the exhaust gas from the administrator terminal 310, the control unit 270 sets the measurement time setting window to the administrator terminal 310 .

If the temperature of the exhaust gas measured by the first measuring unit 210 is higher than the reference temperature value of 60 DEG C, the control unit 270 transmits a notification message informing of the waste heat recovery and the abnormal operation of the white smoke reducing apparatus 100 Lt; / RTI >

If the humidity of the exhaust gas measured by the first measuring unit 210 is higher than the reference humidity value of 40%, the control unit 270 may transmit a notification message informing of the waste heat recovery and the abnormal operation of the white smoke reducing apparatus 100 Lt; / RTI >

The control unit 270 controls the second measurement unit 220 to transmit the notification of the abnormal operation of the waste heat recovery and white smoke reduction apparatus 100 to the administrator terminal 310 and to set the hygroscopic salt concentration to Can be measured.

If the concentration of the hygroscopic salt measured by the second measuring unit 220 is within the reference range of 40 to 80% by weight, the control unit 270 transmits a notification message informing of the waste heat recovery and the abnormal operation of the white smoke reducing apparatus 100 Or may be retransmitted to the administrator terminal 310, or the waste heat recovery and the operation of the white smoke reducing apparatus 100 may be stopped.

The reason for this is that although the measured hygroscopic salt concentration is within the normal range, the increase in the temperature and humidity of the exhaust gas is due to the fact that the waste heat recovery and the white smoke reduction device operate abnormally due to other failure causes, Or re-transmitting the notification message or stopping the operation of the apparatus.

The control unit 270 can also control the waste heat recovery and white smoke reducing apparatus 100 so that the hygroscopic salt concentration measured by the second measuring unit 220 is not within the reference range .

Here, the controller 270 controls the first measuring unit 210 to measure the temperature and humidity of the exhaust gas once the concentration of the hygroscopic salt concentration is adjusted, and at least one of the temperature and the humidity of the re- It is possible to regenerate the notification message informing the waste heat recovery and the abnormal operation of the white smoke reduction device 100 and to retransmit the alarm message to the administrator terminal 310 or to stop the operation of the waste heat recovery and white smoke reduction device 100 .

If the concentration of the hygroscopic salt measured from the second measurement unit 220 is not within the reference range, the control unit 270 may transmit a request message requesting adjustment of the hygroscopic salt concentration including the adjustment value of the hygroscopic salt concentration And transmits it to the administrator terminal 310.

Here, the manager can directly adjust the hygroscopic salt concentration upon receiving the request message, and the manager can adjust the hygroscopic salt concentration through the administrator terminal 310 and transmit the adjustment completion signal to the monitoring system 200.

The control unit 270 controls the first measuring unit 210 to measure the temperature and the humidity of the exhaust gas when the control unit 270 receives an adjustment completion signal of the hygroscopic salt concentration corresponding to the request message from the administrator terminal 310 If at least one of the temperature and the humidity of the re-measured exhaust gas is greater than the reference value, a notification message informing the waste heat recovery and abnormal operation of the white smoke reducing apparatus 100 is regenerated and retransmitted to the administrator terminal 310, The operation of the recovery and white smoke reducing apparatus 100 may be stopped.

Alternatively, when the concentration of the hygroscopic salt measured by the second measuring unit 220 is within the reference range, the control unit 270 determines that the contact ratio between the exhaust gas measured from the third measuring unit 230 and the hygroscopic salt It is determined whether or not the contact time between the measured exhaust gas and the hygroscopic salt is within the second set range and if the measured contact ratio is within the first set range and the measured contact time is within the second set range, If it is within the setting range, the notification message informing the waste heat recovery and the abnormal operation of the white smoke reducing apparatus 100 may be reproduced and retransmitted to the administrator terminal 310 or the waste heat recovery and the operation of the white smoke reducing apparatus 100 may be stopped.

The reason for this is that although the measured hygroscopic salt concentration is within the normal range and the contact ratio between the exhaust gas and the hygroscopic salt and the contact time are within the normal range and the temperature and humidity of the exhaust gas increase, The reduction device is abnormally operated due to another failure cause, so that the notification message is regenerated and retransmitted or the operation of the device is stopped for protection and safety of the device.

Here, the contact ratio between the exhaust gas and the hygroscopic salt is about 1: 2 to about 1:10 in weight ratio, and the contact time is about 5 seconds or more in the second setting range.

If the measured contact ratio is not within the first setting range, or if the measured contact time is not within the second setting range, the controller 270 controls the waste heat recovery and white smoke reduction device Can be controlled.

Here, when the contact ratio and the contact time are adjusted, the control unit 270 controls the first measuring unit 210 to re-measure the temperature and humidity of the exhaust gas, and at least the temperature and the humidity of the re- If any one of them is larger than the reference value, the notification message informing the waste heat recovery and the abnormal operation of the white smoke reduction apparatus 100 is regenerated and retransmitted to the administrator terminal 310, or the waste heat recovery and the operation of the white smoke reduction apparatus 100 are stopped It is possible.

If the measured contact ratio is not within the first setting range or the measured contact time is not within the second setting range, the control unit 270 may request the adjustment of the contact ratio and the contact time And transmits it to the administrator terminal 310.

At this time, upon receiving the request message, the manager can directly adjust the contact ratio between the exhaust gas and the hygroscopic salt and the contact time, and the manager can control the contact ratio between the exhaust gas and the hygroscopic salt through the manager terminal 310, Adjust the contact time, and send the calibration complete signal to the monitoring system 200.

The control unit 270 controls the first measuring unit 210 to adjust the temperature and humidity of the exhaust gas when the contact ratio and the contact time adjustment completion signal are received from the administrator terminal 310 in response to the request message If at least one of the temperature and the humidity of the re-measured exhaust gas is greater than the reference value, a notification message informing the waste heat recovery and abnormal operation of the white smoke reducing apparatus 100 is regenerated and retransmitted to the administrator terminal 310 Or stop the operation of waste heat recovery and white smoke reduction apparatus 100.

As described above, the present invention provides a notification message of the waste heat recovery and the operation state of the white smoke reducing device by measuring the temperature and the humidity of the exhaust gas discharged from the waste heat recovery and white smoke reduction device, Thereby enabling efficient management of the apparatus.

In addition, the present invention can determine the recovery of waste heat and the abnormal operation of the white smoke reducing apparatus by measuring the contact ratio between the exhaust gas and the hygroscopic salt and the contact time when the waste heat recovery and white smoke reducing apparatus are in an abnormal operation, Can be detected quickly and accurately.

Here, the circulation supply part 32 may include a pump, a heat condensing part 40, and a heat exchange part 50.

The pump circulates the solution 34 containing the hygroscopic salts from the exchange part 30 to supply the solution containing the hygroscopic salts to the upper part of the exchange part 30. [

Subsequently, when a part of the solution 34 containing the hygroscopic salts circulating from the lower part of the exchange part 30 flows, the heated and concentrated part 40 heats and concentrates the introduced solution 34 with high pressure steam , The solution 34 containing the concentrated hygroscopic salts is supplied again to the lower part of the exchange part 30 through the pipe 41 at the elevated temperature and the condensed water can be recovered.

The heat exchanging unit 50 can obtain hot water by performing heat exchange from the solution 34 containing the hygroscopic salts circulated by the pump from the lower part of the exchanging unit 30. [

Thus, the waste heat recovery and white smoke reducing apparatus constructed as described above can reduce the white smoke and treat it with high efficiency by lowering the temperature and the humidity of the exhaust gas by using the solution 34 containing hygroscopic salts.

Accordingly, the monitoring system of the present invention monitors the waste heat recovery and white smoke reduction device of this structure periodically to check whether abnormal operation has occurred, to provide abnormal operation information to a manager in a notification message to an administrator, It is possible to quickly perform the maintenance and repair according to the abnormal operation.

Here, the reference value for the temperature of the exhaust gas is 60 占 폚, and the reference value for the humidity of the exhaust gas may be 40%.

Next, if the monitoring system is found to be larger than the reference value, the monitoring system may generate a notification message informing the waste heat recovery and the abnormal operation of the white smoke reduction device to the administrator terminal (S40)

Then, the monitoring system measures the hygroscopic salt concentration from the waste heat recovery and the white smoke reduction device (S50).

Next, the monitoring system checks whether the measured hygroscopic salt concentration is within the reference range (S60)

Here, the reference range for the hygroscopic salt concentration may be about 40-80 wt%.

Next, the monitoring system checks whether at least one of temperature and humidity of re-measured exhaust gas is larger than the reference value (S311)

Optionally, the monitoring system determines in step S303 that the measured contact ratio is within the first setting range and the measured contact time is within the second setting range, If the measured contact time is not within the setting range or the measured contact time is not within the second setting range, a request message requesting adjustment of the contact ratio and the contact time can be generated and transmitted to the administrator terminal (S313)

Then, the monitoring system checks whether the contact ratio and the contact time adjustment completion signal corresponding to the request message are received from the administrator terminal (S315)

Then, when the adjustment completion signal is received, the monitoring system re-measures the temperature and humidity of the exhaust gas (S317)

Next, the monitoring system checks whether at least one of temperature and humidity of re-measured exhaust gas is larger than the reference value (S319)
