[0038] like Figure 1 As shown, the high-temperature condensate recovery and filtration application device disclosed in the present invention includes a storage mechanism, a boiler reflux mechanism and an air conditioning bellows humidification and heating mechanism.

[0039] 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 filter unit 2 is laid in the condensate storage tank 1 along the width direction of the condensate storage tank 1. The storage filter unit 2 can be, for example, a screen filter.

[0040] 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 .

The water outlet 102 is connected to the condensate return valve 6, the softened water tank 7, the boiler inlet pump 8 and the boiler 9 in sequence through a pipeline. When the condensate in the condensate storage tank 1 needs to be output to the boiler 9, the condensate return valve 6 is opened, and the condensate flows through the water outlet 102, the condensate return valve 6, the softened water tank 7 and the boiler inlet pump 8 in sequence, and enters the boiler 9.

[0043] The air conditioning bellows humidification and heating mechanism includes a condensate high pressure valve 10 and a hot mist humidifier 12. The water outlet 102 is sequentially connected to the condensate high pressure valve 10 and the hot mist humidifier 12 through a pipeline to spray humidify and heat the air flow in the air conditioning bellows. When the condensate in the condensate storage tank 1 needs to be output to the air conditioning bellows, the condensate high pressure valve 10 is opened, and the condensate flows through the water outlet 102, the condensate high pressure valve 10 and the hot mist humidifier 12 in sequence and enters the air conditioning bellows.

[0044] The high-temperature condensate recovery and filtration application device disclosed in the present invention stores the condensate in a storage mechanism, and the condensate can be supplied to the boiler 9 through a boiler reflux mechanism, or supplied to the air-conditioning bellows through an air-conditioning bellows humidifying and heating mechanism, effectively ensuring the collection and utilization of the high-temperature condensate.

[0045] In one embodiment of the high-temperature condensate recovery and filtration application device disclosed herein, in order to improve the utilization efficiency of the high-temperature condensate, the sewage outlet 103 and the exhaust outlet 104 are respectively located at two ends of the condensate storage tank 1 .

[0046] In one embodiment of the high-temperature condensate recovery and filtration application device disclosed in the present invention, in order to improve the utilization efficiency of the high-temperature condensate, 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.

[0047] In one embodiment of the high-temperature condensate recovery and filtration application device disclosed herein, in order to improve the utilization efficiency of the high-temperature condensate, the storage tank water level detection unit 4 is located below the storage tank temperature detection unit 5 .

[0048] 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 .

[0049] In one embodiment of the high-temperature condensate recovery and filtration application device disclosed herein, in order to improve the utilization efficiency of high-temperature condensate, the connecting pipe between the condensate direct return valve 6 and the water outlet 102 and the connecting pipe between the condensate high-pressure valve 10 and the water outlet 102 are arranged in parallel.

[0050] Furthermore, a condensate booster pump 13 is provided on the parallel pipelines between the condensate direct return valve 6 and the water outlet 102 and between the condensate high-pressure valve 10 and the water outlet 102 .

[0051] In one embodiment of the high-temperature condensate recovery and filtration application device disclosed in the present invention, in order to improve the utilization efficiency of high-temperature condensate, the air-conditioning bellows humidification and heating mechanism also includes a condensate high-pressure filter 11, and the condensate high-pressure filter 11 is arranged between the condensate high-pressure valve 10 and the hot mist humidifier 12.

[0052] In one embodiment of the high-temperature condensate recovery and filtration application device disclosed in the present invention, in order to improve the utilization efficiency of the high-temperature condensate, the storage mechanism also includes a silk-making reel condensate pump 14 and a power air-conditioning condensate pump 15. The silk-making reel condensate pump 14 and the power air-conditioning condensate pump 15 are connected to the water inlet 101 through a pipeline. In specific implementation, the silk-making reel condensate pump 14 and the power air-conditioning condensate pump 15 can be arranged in parallel.

[0053] like Figure 2 As shown, the present disclosure also provides a method for applying the high-temperature condensate recovery and filtration device based on the present disclosure.

[0054] The high-temperature condensate water recovery and filtration application method comprises the following steps:

[0055] It is determined whether the water level in the condensate storage tank 1 is greater than the preset output water level and whether the water level in the condensate storage tank 1 is greater than the boiler return water level, and the boiler return water level is higher than the preset output water level. The above preset output water and boiler return water levels can be flexibly set according to actual needs. The water level in the condensate storage tank 1 first reaches the preset output water level and then reaches the boiler return water level.

[0056] When the water level in the condensate storage tank 1 is not greater than the preset output water level, it indicates that the amount of water in the condensate storage tank 1 is insufficient and the condensate output condition is not met. At this time, the condensate direct return valve 6 and the condensate high pressure valve 10 can be closed to prevent the condensate in the condensate storage tank 1 from entering the application step.

[0057] If the water level in the condensate storage tank 1 is greater than the preset output water level and the water level in the condensate storage tank 1 is greater than the boiler return water level, the condensate direct return valve 6 is opened and the condensate high-pressure valve 10 is closed, so that the condensate in the condensate storage tank 1 flows from the outlet 102 through the condensate direct return valve 6, the softened water tank 7 and the boiler inlet pump 8 in sequence, and enters the boiler 9.

[0058] When the water level in the condensate storage tank 1 is greater than the preset output water level and the water level in the condensate storage tank 1 is greater than the boiler return water level, it indicates that the condensate in the condensate storage tank 1 has approached its maximum storage limit. In order to avoid the waste of condensate overflow, the condensate in the condensate storage tank 1 enters the boiler utilization step. That is, the condensate direct return valve 6 is opened and the condensate high-pressure valve 10 is closed, and the condensate in the condensate storage tank 1 flows through the outlet 102, the condensate direct return valve 6, the softened water tank 7 and the boiler inlet pump 8 in sequence, and finally enters the boiler 9.

[0059] If the water level in the condensate storage tank 1 is greater than the preset output water level and the water level in the condensate storage tank 1 is less than the boiler return water level, it is determined whether the temperature and humidity values ​​of the air conditioning supply air outlet are less than the preset temperature and humidity values ​​and whether the temperature in the condensate storage tank 1 is higher than the output temperature.

[0060] When the water level in the condensate storage tank 1 is greater than the preset output water level and the water level in the condensate storage tank 1 is less than the boiler return water level, it indicates that the condensate in the condensate storage tank 1 is insufficient to meet the boiler utilization demand, but the condensate in the condensate storage tank 1 can be used. At this time, it can be determined whether the temperature and humidity of the air flow in the air conditioner bellows need to be adjusted.

[0061] If the temperature and humidity values ​​of the air supply outlet of the air conditioner are lower than the preset temperature and humidity values ​​and the temperature in the condensate storage tank 1 is higher than the output temperature, the condensate high-pressure valve 10 is opened and the condensate direct return valve 6 is closed, so that the condensate in the condensate storage tank 1 flows from the water outlet 102 through the condensate high-pressure valve 10 and the hot mist humidifier 12 in sequence to perform hot mist humidification and heating on the air flow in the air conditioner bellows.

[0062] When the temperature and humidity value of the air supply outlet of the air conditioner 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 temperature and humidity of the air flow in the air conditioner bellows need to be adjusted, and the temperature of the condensate in the condensate storage tank 1 can meet the air conditioning demand. At this time, the condensate high-pressure valve 10 can be opened and the condensate direct return valve 6 can be closed, and the condensate in the condensate storage tank 1 flows through the water outlet 102, the condensate high-pressure valve 10 and the hot mist humidifier 12 in sequence, thereby performing hot mist humidification and heating on the air flow in the air conditioner bellows.

[0063] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
