That is, the waste heat is introduced into the main body 110 through the inlet 120 and discharged through the exhaust 130.

The condensate recovery unit 300 is provided in the storage unit 140 to recover the condensed water. The condensed water stored in the receiving part 140 is in a state of being heated to a high temperature by heat exchange with the waste heat inside the body part 110 (for example, 99 ° C or less). When such condensed water is recovered, energy stored in the condensed water can be utilized.

The condensing water recovery unit 300 includes a water supply unit 310 for supplying cooling water to the main body 110, a condensed water discharge unit 320 for recovering condensed water, a heat exchange unit for performing heat exchange between the condensed water and the outside air (330).

The outside air recovery unit 400 is disposed outside the main body 110 and recovers the outdoor heat exchanged with the condensed water stored in the storage unit 140.

That is, since the condensed water stored in the accommodating portion 140 is heated to a high temperature, the outside air is heated by heat exchange with the condensed water and then recovered.

That is, the water supply pipe 311 of the water supply part 310 is connected to the body part 110 after passing through the heat exchange part 330. Therefore, the condensed water flowing in the water supply pipe 311 inside the heat exchanging part 330 is heated to a high temperature.

The outside air return pipe 420 exchanges heat with the water supply pipe 311 inside the heat exchanging part 330 so that the outside air inside the outside air return pipe 420 is heated and discharged to the outside to be recovered and used in a dryer.

The outside air recovery pipe 420 is provided with a recovery valve V1 to control the flow of the outside air.

An outside air discharge pipe 430 branched from the outside air return pipe 420 and directed toward the inside of the main body 110 is provided. This is because, when the humidity of the waste heat discharged through the exhaust port 130 is high, the white smoke may occur. To prevent this, the hot outside air is supplied into the main body 110 through the outside air discharge pipe 430.

The outside air discharge pipe 430 is provided with a discharge valve V2 to intercept the flow of outside air supplied into the main body 110.

The exhaust steam measuring unit 210 of the measuring unit 200 measures the flow rate, humidity, and temperature of the exhaust gas provided in the exhaust port 130.

In order to measure the flow rate, a well-known flow meter may be used, a humidity sensor may be used, and a temperature sensor may be used. Such a flow meter, a humidity sensor and a temperature sensor are well known in the art, so that detailed description and illustration are omitted.

The outside air measuring unit 220 for measuring the humidity and temperature of the outside air is provided inside the outside air return pipe 420 of the outside air collecting unit 400.

The inlet steam measuring unit 230 provided in the inlet 120 of the main body 110 measures the temperature and humidity of the waste heat flowing through the inlet 120.

The condensed water recovered in the main body 110 using the energy recovery apparatus 10 of the present invention as described above is heat-exchanged with the waste heat and is then discharged to the outside by the condensed water discharge unit 320. The heat exchange unit The outside air heated by the outside air recovery unit 400 is recovered.

Hereinafter, a waste heat energy recovery method using the recovery apparatus 10 of the present invention will be described with reference to Figs. 2 to 4. Fig.

The cooling water supplied to the inside of the main body 110 is heat-exchanged with the waste heat and is then discharged to the outside by the condensed water discharging unit 320. The outside air heated by the heat exchanging unit 330 is discharged to the outside air Is operated by a method that is recovered by the unit (400).

However, if the humidity of the waste heat discharged through the exhaust part 130 of the main body part 110 is equal to or higher than the preset value, there is a risk of white smoke. If the water level of the condensed water in the storage part 140 is lower than the set value, The discharge of the condensed water is stopped.

The whitening phenomenon occurs in an environment where the heated humidifier is cooled when cooled below the dew point in the process of dilution with the cold air and is cooled under the condition of the upper side of the 100% saturation curve of the moisture diagram.

In particular, white smoke occurs when warm discharge air is mixed with cold air.

That is, the waste heat discharged from the chimney and the like is mixed with the outside air at the moment when it is discharged into the high temperature and high humidity air, and the temperature suddenly drops. Since the humidity can not exist theoretically more than 100% at this time, the supersaturated water vapor is made into water droplets with the temperature drop, and the water droplets generated by the reflection of light cause white smoke appearance like white smoke.

These white smoke are not pollutants, but they appear to be visible pollutants that visually burden them when viewed from the outside. They also cause discomfort due to excessive water droplets falling into the chimneys and ice phenomena that fall on the road and freeze in winter There is a problem.

In order to prevent the occurrence of the white smoke phenomenon, even when energy is being recovered by the energy recovery apparatus 10 of the present invention, when the humidity of the waste heat discharged through the exhaust unit 130 of the main body unit 110 is equal to or higher than the set value, The amount of condensed water supplied into the main body 110 is increased.

By this method, the water vapor of more waste heat is liquefied with the cooling water, falls into the receiving part 140, and the white smoke phenomenon is prevented.

On the other hand, when the water level of the condensed water in the accommodating portion 140 is less than the predetermined value, the quantity of the condensed water is insufficient and white smoke may occur, so that the discharge of the condensed water is stopped.

The humidity of the waste heat can be measured by the exhaust steam measuring unit 210 and the measured result is determined by the control unit CON to stop the operation of the pump P2 of the condensed water discharge unit 320 to discharge the condensed water . ≪ / RTI >

The condensed water level of the storage part 140 can be measured by the water level measuring part 240 and the measured result is determined by the control part CON and the operation of the pump P2 of the condensed water discharge part 320 To stop the condensate discharge.

Hereinafter, the method (S100) of the present invention will be described in more detail.

First, the water supply unit 310 is operated to supply the cooling water to the main body 110 (S110; At this time, the control unit CON may drive the pump P1 to supply the cooling water to the main body 110.

Thereafter, it is confirmed whether the humidity of the waste heat discharged through the exhaust unit 130 is lower than the set value (S120;

In the second step S120, the humidity of the waste heat is measured by the exhaust steam measuring unit 210, and it is determined by the control unit CON whether the humidity is lower than the set value.

If it is determined that the humidity of the waste heat is lower than the set value in the second step S120, the white waste phenomenon does not occur. Therefore, the energy recovery apparatus 10, that is, the outside air recovery unit 400 and the condensate recovery unit 300 (S130; hereinafter referred to as the third step)

In the third step S130, the condensed water is discharged by the condensed water discharge unit 320, and the control unit CON drives the pump P2 to discharge the condensed water to the outside.

The temperature of the discharged condensed water is measured by the temperature measurement 250 installed in the receiving part 140. When the temperature of the condensed water is out of the set range, the controller CON stops the operation of the pump P2, You can stop.

The condensed water discharge pipe 322 of the condensed water discharge unit 320 is provided with a filter 323 to prevent foreign matter from being discharged to the outside.

The outside air that is recovered to the outside can be measured for temperature and humidity by the outside air measurement unit 220 and the control unit CON provided in the outside air return pipe 420 to check whether or not the outside air can be used in a dryer or the like. Further, the control unit (CON) operates the recovery valve (V1) to interrupt the outside air flowing in the outside air return pipe (420).

If the humidity of the waste heat is equal to or higher than the set value in the second step S120, white flue phenomenon may occur. Therefore, the step S440 of checking the humidity of the waste heat again without operating the energy recovery apparatus 10 ).

After the third step (S130), it is checked whether the condensed water level in the receiving portion 140 is lower than the set value (hereinafter referred to as the fifth step)

The water level of the condensed water is confirmed by the water level measuring unit 240 and the control unit CON.

If the condensate water level is lower than the set value by the fifth step S150, the discharge of the condensed water is stopped and the condensate water level is checked again to determine whether the condensate water level is lower than the set value (S160; ).

At this time, the discharge of the condensed water is stopped in the sixth step S160, but the outside air can be continuously recovered by the outside air recovery unit 400. [

Of course, the discharge valve V2 can supply outside air to the main body 110 as needed through the outside air discharge pipe 312. The discharge valve V2 can be controlled by the control unit CON to be.

If it is determined in the fifth step S150 that the condensed water level is equal to or higher than the predetermined value, then the condensed water is not exhausted, so that the condensed water discharge is maintained and the humidity of the waste heat discharged is again less than the set value (S170; .

This is because the humidity of the waste heat is confirmed by the second step S120, but the humidity of the waste heat may rise again due to the driving of the energy recovery device 10, so that the white smoke may occur. I will check again.

If the humidity of the waste heat discharged in the seventh step (S170) is equal to or higher than the set value, white smoke may occur, so stop discharging the condensed water and check whether the humidity of the waste air is lower than the set value (S180; Hereinafter referred to as the eighth step).

At this time, the outside air can be continuously collected by the outside air recovery unit 400, and the outside air can be supplied to the main body unit 110 through the outside air discharge pipe 430, Or by driving the discharge valve V2.

If the humidity of the waste heat discharged in the seventh step S170 is less than the set value, there is less possibility of occurrence of the white smoke phenomenon, the energy recovery apparatus 10 is continuously operated and the condensed water level of the storage unit 140 is set to the set value (S190) is performed again (S190)

The temperature and humidity of the waste heat flowing into the main body 110 through the inlet 120 can be checked by the inlet steam measuring unit 230 and the control unit CON.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.
