[0002] During the cigarette production process, a large amount of high-temperature condensed water often appears in the pipeline. Most of this high-temperature condensed water is directly discharged, resulting in a great waste.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] like Figure 1 As shown, the water heater application device of high-temperature condensate water disclosed in the present invention includes a storage mechanism, an intermediate connection mechanism and a water heater mechanism.

[0045] The storage mechanism includes a condensate storage tank 1, a storage filter unit 2, a storage tank exhaust valve 3, a storage tank water level detection unit 4 and a storage tank temperature detection unit 5. The condensate storage tank 1 is provided with a water inlet 101, a water outlet 102, a sewage outlet 103 and an exhaust port 104.

The storage tank exhaust valve 3 is connected to the exhaust port 104. When exhaust is required, the storage tank exhaust valve 3 is opened, and the air accumulated in the condensate storage tank 1 is discharged from the exhaust port 104.

[0046] The water outlet 102 , the air outlet 104 , the storage tank water level detection unit 4 and the storage tank temperature detection unit 5 are all located above the storage filter unit 2 , and the air outlet 104 is located above the water outlet 11 .

[0047] The water inlet 101 and the sewage outlet 103 are both located below the storage and filtration unit 2, and the water inlet 101 is located above the sewage outlet 103. The sewage outlet 103 can be used to discharge the precipitated impurities of the storage and filtration unit 2 out of the condensate storage tank 1.

[0048] The intermediate connection mechanism includes a condensate booster pump 6 and a water-heating electromagnetic main valve 7. The two ends of the condensate booster pump 6 are respectively connected to the water outlet 102 and the water-heating electromagnetic main valve 7. When the water-heating electromagnetic main valve 7 is opened, the intermediate connection mechanism is in a connected state. When the water-heating electromagnetic main valve 7 is closed, the intermediate connection mechanism is in a disconnected state.

[0049] The water heater mechanism includes a first water heater 8 , a second water heater 9 , a third water heater 10 , a first water heating solenoid valve 11 , a second water heating solenoid valve 12 , a third water heating solenoid valve 13 , a fourth water heating solenoid valve 14 , a fifth water heating solenoid valve 15 and a sixth water heating solenoid valve 16 .

[0050] The first water heater 8, the second water heater 9 and the third water heater 10 are connected in parallel, and one end of the first water heater 8, the second water heater 9 and the third water heater 10 connected in parallel is connected to the water heater electromagnetic main valve 7, and the other end of the first water heater 8, the second water heater 9 and the third water heater 10 connected in parallel is provided with a water heater water outlet manifold 17. Each water heater can be used to heat the air supply of the air conditioner, and the cooling water after the water heater air supply is heated can enter the water heater water outlet manifold 17 to discharge the high-temperature condensed water of the water heater application device.

[0051] The first water-heating solenoid valve 11 is arranged at one end of the water outlet of the first water heater 8. The second water-heating solenoid valve 12 and the third water-heating solenoid valve 13 are respectively arranged at one end of the water inlet and one end of the water outlet of the second water heater 9. The fourth water-heating solenoid valve 14 is arranged at one end of the water inlet of the third water heater 10. The two ends of the fifth water-heating solenoid valve 15 are respectively connected to the pipe between the first water heater 8 and the first water-heating solenoid valve 11 and the pipe between the second water heater 9 and the second water-heating solenoid valve 12. The two ends of the sixth water-heating solenoid valve 16 are respectively connected to the pipe between the second water heater 9 and the third water-heating solenoid valve 13 and the pipe between the third water heater 10 and the fourth water-heating solenoid valve 14. The water inlet of the above-mentioned water heater refers to the side of the water heater adjacent to the water-heating solenoid main valve 7, and the water outlet of the water heater refers to the side of the water heater adjacent to the water heater outlet manifold 17.

[0052] By controlling the on and off of the first water heating solenoid valve 11, the second water heating solenoid valve 12, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16, the working state of each water heater (i.e. whether to heat the air supply to the air-conditioning outlet) can be controlled, thereby adjusting the temperature and humidity of the air-conditioning supply outlet.

[0053] The water heater application device for high-temperature condensate water disclosed in the present invention stores condensate water in a storage mechanism, and the condensate water can be supplied to the water heater mechanism through an intermediate connecting mechanism, and the air supply heating for the air conditioner is controlled by supplying water to each water heater of the water heater mechanism, thereby effectively ensuring the collection and utilization of high-temperature condensate water.

[0054] In one embodiment of the water heater application device of high-temperature condensate water disclosed in the present invention, in order to improve the utilization efficiency of high-temperature condensate water, the sewage outlet 103 and the exhaust outlet 104 are respectively located at two ends of the condensate water storage tank 1.

[0055] In one embodiment of the high-temperature condensate water heater application device disclosed herein, in order to improve the utilization efficiency of the high-temperature condensate water, the distance between the water inlet 101 and the storage and filtration unit 2 along the central axis direction of the condensate storage tank 1 is greater than the distance between the water outlet 102 and the storage and filtration unit 2 along the central axis direction of the condensate storage tank 1.

[0056] In one embodiment of the water heater application device for high-temperature condensate water disclosed herein, in order to improve the utilization efficiency of high-temperature condensate water, the storage tank water level detection unit 4 is located below the storage tank temperature detection unit 5 .

[0057] Furthermore, the storage tank water level detection unit 4 and the storage tank temperature detection unit 5 are both located above the water outlet 102 .

[0058] In one embodiment of the water heater application device of the high-temperature condensate disclosed in the present invention, in order to improve the utilization efficiency of the high-temperature condensate, the storage mechanism also includes a silk reel condensate pump 18 and a power air conditioning condensate pump 19. The silk reel condensate pump 18 and the power air conditioning condensate pump 19 are connected to the water inlet 101 through a pipeline. In specific implementation, the silk reel condensate pump 18 and the power air conditioning condensate pump 19 can be arranged in parallel.

[0059] like Figure 2 As shown, the present disclosure also provides a method for applying high-temperature condensate water to a water heater based on the high-temperature condensate water application device of the present disclosure, comprising the following steps:

[0060] It is determined whether the temperature and humidity value of the air supply outlet of the air conditioner is less than the preset temperature and humidity value and whether the temperature in the condensate storage tank 1 is higher than the output temperature. The output temperature may be 50°C, for example.

[0061] When the temperature and humidity values ​​of the air conditioning outlet are not less than the preset temperature and humidity values ​​and the temperature in the condensate storage tank 1 is lower than the output temperature, it means that the water heater application device for high-temperature condensate does not meet the conditions for heating the air conditioning outlet, and the condensate booster pump 6 can be turned off.

[0062] If the temperature and humidity value of the air-conditioning air supply outlet is less than the preset temperature and humidity value and the temperature in the condensate storage tank 1 is higher than the output temperature, it indicates that the water heater application device of the high-temperature condensate meets the conditions for heating the air supply to the air-conditioning outlet, and the condensate booster pump 6 is turned on. At this time, it can be further judged whether the air flow in the air-conditioning box needs to be heated and whether the water level in the condensate storage tank 1 can meet the heating demand. Therefore, when the temperature and humidity value of the air-conditioning air supply outlet is less than the preset temperature and humidity value and the temperature in the condensate storage tank 1 is higher than the output temperature, the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is calculated, and the water level of the condensate storage tank 1 is obtained, so as to control the opening and closing of the water heating electromagnetic main valve 7 according to the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet and the water level of the condensate storage tank 1. By controlling the opening and closing of the water heating electromagnetic main valve 7, the on-off of the intermediate connecting mechanism can be controlled.

[0063] Specifically, the opening and closing of the water heating electromagnetic main valve is controlled according to the difference between the preset temperature value and the temperature value of the air supply outlet of the air conditioner and the water level of the condensate storage tank 1 as follows:

[0064] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is less than 1.5°C and / or the water level of the condensate storage tank 1 is less than 1.6m, the water heating electromagnetic main valve 7 is closed.

[0065] When the difference between the preset temperature value and the air outlet temperature of the air conditioner is less than 1.5°C and / or the water level of the condensate storage tank 1 is less than 1.6m, it means that the air flow in the air conditioner does not need to be heated, or the water level of the condensate storage tank 1 is low. At this time, the water heating electromagnetic main valve 7 is closed to prevent condensate from entering the water heater mechanism.

[0066] If the difference between the preset temperature value and the temperature value of the air-conditioning supply air outlet is greater than 1.5°C and the water level of the condensate storage tank 1 is greater than 1.6m, the water heating electromagnetic main valve 7 is opened, and at least one of the first water heater 8, the second water heater 9 and the third water heater 10 is controlled to operate according to the difference between the preset temperature value and the temperature value of the air-conditioning supply air outlet and the water level of the condensate storage tank 1.

[0067] When the difference between the preset temperature value and the temperature value of the air supply outlet of the air conditioner is greater than 1.5°C and the water level of the condensate storage tank 1 is greater than 1.6m, it indicates that the air flow in the air conditioner needs to be heated and the water volume in the condensate storage tank 1 meets the output conditions. At this time, the water heating electromagnetic main valve 7 can be opened to allow the water in the condensate storage tank 1 to flow to each water heater, and the temperature of the air supply outlet of the air conditioner is adjusted by heating the air supply to the air conditioner outlet. The working states of the first water heater 8, the second water heater 9 and the third water heater 10 in the present disclosure can be flexibly selected according to actual needs.

[0068] In one embodiment of the high-temperature condensate water heater application method, at least one of the first water heater 8, the second water heater 9 and the third water heater 10 is controlled to work as follows according to the difference between the preset temperature value and the air supply outlet temperature of the air conditioner and the water level of the condensate storage tank 1:

[0069] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 7.5° C. and the water level of the condensate storage tank 1 is greater than 3 m, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16 are closed.

[0070] When the difference between the preset temperature value and the temperature value of the air supply outlet of the air conditioner is greater than 7.5°C and the water level of the condensate storage tank 1 is greater than 3m, it indicates that the air flow in the air conditioner box needs to be heated up greatly and the amount of water in the condensate storage tank 1 is sufficient. In order to make the high-temperature condensate quickly increase the air supply temperature of the air conditioner, close the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16, and the high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, and enters the first water heater 8, the second water heater 9 and the third water heater 10 respectively, and heats the air supply of the air conditioner through the first water heater 8, the second water heater 9 and the third water heater 10. The water flowing out of the first water heater 8, the second water heater 9 and the third water heater 10 converges to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0071] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 7.5°C and the water level of the condensate storage tank 1 is less than 3m and greater than 1.7m, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15 are closed.

[0072] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 7.5°C and the water level of the condensate storage tank 1 is less than 3m and greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet needs to be increased. In order to make full use of the high-temperature condensate to quickly increase the air-conditioning air supply temperature, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15 are closed, and the high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, and enters the first water heater 8 and the second water heater 9 respectively. The high-temperature condensate entering the first water heater 8 is heated by the air-conditioning air supply and passes through the first water heating solenoid valve 11, and then merges into the water heater outlet manifold 17 and leaves the water heater mechanism. The high-temperature condensate entering the second water heater 9 is heated by the air conditioning supply air, and then passes through the sixth water heating solenoid valve 16 to enter the third water heater 10 to heat the air conditioning supply air. The water flowing out of the third water heater 10 converges to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0073] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 5°C and less than 7.5°C and the water level of the condensate storage tank 1 is greater than 1.7m, close the first water heating solenoid valve 11, the second water heating solenoid valve 12, the third water heating solenoid valve 13 and the fourth water heating solenoid valve 14.

[0074] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 5°C and less than 7.5°C and the water level of the condensate storage tank 1 is greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet does not need to be increased too much. In order to make full use of the high-temperature condensate to increase the air-conditioning air temperature, close the first water heating solenoid valve 11, the second water heating solenoid valve 12, the third water heating solenoid valve 13 and the fourth water heating solenoid valve 14. The high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, enters the first water heater 8 to heat the air-conditioning supply, leaves the first water heater 8, and enters the second water heater 9 and the third water heater 10 in turn to heat the air-conditioning supply. The water flowing out of the third water heater 10 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0075] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 3°C and less than 5°C and the water level of the condensate storage tank 1 is greater than 1.7m, close the first water heating solenoid valve 11, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15.

[0076] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 3°C and less than 5°C and the water level of the condensate storage tank 1 is greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet does not need to be increased much. In order to make full use of the high-temperature condensate to increase the air-conditioning air temperature, close the first water heating solenoid valve 11, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15. The high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, enters the second water heater 9 to heat the air-conditioning air, and then enters the third water heater 10 to heat the air-conditioning air. The water flowing out of the third water heater 10 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0077] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 1.5°C and less than 3°C and the water level of the condensate storage tank 1 is greater than 1.7m, close the second water heating solenoid valve 12, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16.

[0078] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 1.5°C and less than 3°C and the water level of the condensate storage tank 1 is greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet needs to be increased less. In order to increase the air-conditioning air supply temperature, close the second water heating solenoid valve 12, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16. The high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, enters the first water heater 8 to heat the air-conditioning air supply, and the water flowing out of the first water heater 8 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0079] By using this method of controlling the operation of the first water heater 8, the second water heater 9 and the third water heater 10, the utilization efficiency of the high-temperature condensed water can be more effectively improved and the waste of the high-temperature condensed water can be avoided.

[0080] Further, in order to more effectively avoid the waste of high-temperature condensate, the specific steps of controlling at least one of the first water heater 8, the second water heater 9 and the third water heater 10 to work according to the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet and the water level of the condensate storage tank 1 are judged in sequence according to the arrangement order. That is, if the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 7.5°C and the water level of the condensate storage tank 1 is not greater than 3m, then it is judged whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 7.5°C and whether the water level of the condensate storage tank 1 is less than 3m and greater than 1.7m. If the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 7.5°C and the water level of the condensate storage tank 1 is not less than 3m and greater than 1.7m, then it is judged whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 5°C and less than 7.5°C and whether the water level of the condensate storage tank 1 is greater than 1.7m. If the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 5°C and less than 7.5°C and the water level of the condensate storage tank 1 is not greater than 1.7m, then determine whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 3°C and less than 5°C and whether the water level of the condensate storage tank 1 is greater than 1.7m. If the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 3°C and less than 5°C and the water level of the condensate storage tank 1 is not greater than 1.7m, then determine whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 1.5°C and less than 3°C and whether the water level of the condensate storage tank 1 is greater than 1.7m. Finally, the appropriate flow mode of high-temperature condensate in the water heater mechanism is obtained.
