Description

Technical Field

[0001] The present invention relates to the technical field of air treatment, and specifically to an air treatment system having dehumidification and sulfur removal functions.

Background Art

[0002] In many fields such as industrial production, warehouse storage logistics, and indoor air conditioning, the control of air humidity and the purification of harmful gases are important parts for ensuring production safety, product quality, and human health. If the humidity in the air is too high, it is easy to cause rusting of equipment, electrical failures, and mold growth on materials. At the same time, it affects human comfort and causes problems such as airway discomfort. Hydrogen sulfide generated during processes such as industrial emissions and fuel combustion not only corrodes equipment, but also pollutes the atmospheric environment, harms the human respiratory system, and may cause serious health risks if exposed for a long time.

[0003] Currently, conventional air treatment equipment always has the defect of a single function. That is, many dehumidification devices can only achieve humidity adjustment and cannot remove harmful gases such as hydrogen sulfide. Conventional sulfur removal devices are often applied to the centralized treatment of industrial exhaust gases, with a huge volume, high energy consumption, and are difficult to adapt to the air purification needs of indoor air conditioning or small and medium-sized places. In addition, some integrated air treatment systems attempt to make the dehumidification and sulfur removal functions compatible, but there are problems such as a complex structure, low treatment efficiency, and high regeneration energy consumption. For example, some systems adopt in-line independent treatment modules, resulting in a large air flow resistance, increased energy consumption. At the same time, in the regeneration process of the adsorption material, there is a lack of an efficient energy recovery mechanism, causing energy waste, and the regeneration effect is not good, so the treatment efficiency is likely to rapidly decrease with the use time.

[0017] The present invention will be further described with reference to the following embodiments.

[0018] In Example 1, as can be seen from Figure 1, the air treatment system having dehumidification and sulfur removal functions described in this embodiment includes a multifunctional rotating wheel 1, the multifunctional rotating wheel 1 includes an adsorption region 11 and a desorption region 12, and a dehumidification module and a sulfur removal module are provided in the adsorption region 11. The air treatment system having dehumidification and sulfur removal functions described in this embodiment further includes a first dehumidification rotating wheel 2, the first dehumidification rotating wheel 2 includes a first dehumidification region 21, a first regeneration region 22 and a cooling region 23. The air treatment system having dehumidification and sulfur removal functions described in this embodiment further comprises a first intermediate surface cooler 30, a first blower 31, a first heater 32, a second heater 33, and a first regeneration fan 34. One end of the adsorption region 11 communicates with one end of the first blower 31 after passing through the first intermediate surface cooler 30, the other end of the first blower 31 communicates with one end of the first dehumidification region 21, and the other end of the first blower 31, the cooling region 23, the first heater 32, the first regeneration region 22, the second heater 33, the detachment region 12, and the first regeneration fan 34 are in sequential communication. The air treatment system having dehumidification and sulfur removal functions described in this embodiment further comprises a first outside air valve 35, a first initial effect filter 36, a first front surface cooler 37, a first rear surface cooler 38, and a first intermediate effect filter 39, wherein the first outside air valve 35, the first initial effect filter 36, the first front surface cooler 37, and the other end of the adsorption region 11 are in sequential communication, the other end of the first dehumidification region 21, the first rear surface cooler 38, and the first intermediate effect filter 39 are in sequential communication, the other end of the adsorption region 11 is used to communicate with one end of the room, and the other end of the first dehumidification region 21 is used to communicate with the other end of the room after passing through the first rear surface cooler 38 and the first intermediate effect filter 39.

[0019] Specifically, in the air treatment system having dehumidification and sulfur removal functions described in this embodiment, outside air enters the system through the first outside air valve 35, first removes impurities such as dust and particulate matter by the first initial effect filter 36 to prevent clogging of the subsequent adsorption module, and then adjusts to an appropriate temperature by the first front surface cooler 37. After that, it flows into the adsorption area 11 of the multi-functional rotating wheel 1, where the dehumidification module in the adsorption area 11 rapidly adsorbs water vapor from the air, and the sulfur removal module simultaneously captures hydrogen sulfide, completing the integrated dehumidification and sulfur removal process. After processing, the air is further temperature-controlled by the first intermediate surface cooler 30 and then transported by the first blower 31 to the first dehumidification area 21 of the first dehumidifying rotating wheel 2 to perform secondary deep dehumidification and ensure that the humidity reaches the standard. At the same time, the first blower 31 separates a portion of the airflow, which flows sequentially through the cooling area 23, the first heater 32, and the first regeneration area 22 of the first dehumidifying rotating wheel 2, heating and regenerating the adsorption material of the first dehumidifying rotating wheel 2. The regenerated airflow is further heated by the second heater 33 and introduced into the desorption area 12 of the multifunctional rotating wheel 1, where it desorbs and detaches the water vapor and hydrogen sulfide adsorbed in the adsorption area 11. Finally, it is discharged by the first regeneration fan 34, forming a stable regeneration closed loop. Finally, the air that has undergone deep dehumidification is sequentially adjusted to a comfortable temperature by the first rear surface cooler 38, purified of fine impurities by the first intermediate effect filter 39, and then returned to the room. At the same time, the other end of the adsorption area 11 is connected to the room's return air, thereby enabling the mixing of outside air and return air.

[0020] This embodiment realizes simultaneous dehumidification and sulfur removal by means of the multifunctional rotating wheel 1, without the need for independent equipment, simplifies the flow, improves the processing efficiency, avoids the problem of increased air flow resistance due to the series connection of multiple modules, and also, through the secondary dehumidification design of the first dehumidifying rotating wheel 2, in combination with the regeneration systems of the cooling region 23, the first heater 32 and the second heater 33, not only guarantees the depth of dehumidification, but also fully regenerates the adsorption material, avoids a decrease in processing efficiency, can extend the service life, and moreover, through the combination of the initial effect filter first and the intermediate effect filter later, effectively blocks impurities of different particle sizes, and through the multi-stage temperature adjustment of the front surface cooler, the intermediate surface cooler and the rear surface cooler, guarantees that the discharged air meets the usage needs in terms of humidity, cleanliness and temperature.

[0021] In Embodiment 2, as can be seen from FIG. 2, different from Embodiment 1, in the air treatment system having the dehumidification and sulfur removal functions described in this embodiment, the multifunctional rotating wheel 1 further includes a temperature reduction region 13. The air treatment system having the dehumidification and sulfur removal functions described in this embodiment further includes a second intermediate surface cooler 41, a second blower 42, a second rear surface cooler 43, a second intermediate effect filter 44, a third heater 45 and a second regeneration fan 46. One end of the second intermediate surface cooler 41 communicates with one end of the second blower 42, the other end of the second blower 42 communicates with one end of the adsorption region 11, the other end of the second intermediate surface cooler 41 is used to communicate with one end of the room, and the other end of the adsorption region 11 is used to communicate with the other end of the room after passing through the second rear surface cooler 43 and the second intermediate effect filter 44. The other end of the second blower 42, the temperature reduction region 13, the third heater 45, the desorption region 12 and the second regeneration fan 46 are sequentially communicated. The air treatment system having the dehumidification and sulfur removal functions described in this embodiment further includes a second air valve 51, a second initial effect filter 52 and a second front surface cooler 53. The second air valve 51, the second initial effect filter 52, the second front surface cooler 53 and the other end of the second middle surface cooler 41 are sequentially communicated. 器43及び第2の中間効果フィルタ44を通過した後に部屋の他端と連通するために用いられ、前記第2の送風機42の他端、降温領域13、第3のヒータ45、脱着領域12及び第2の再生ファン46は順に連通する。本実施例に記載の除湿及び硫黄除去機能を有する空気処理システムは、第2の空気弁51、第2の初期効果フィルタ52及び第2の前部表面冷却器53を更に備え、前記第2の空気弁51、第2の初期効果フィルタ52、第2の前部表面冷却器53及び第2の中表面冷却器の他端は順に連通する。 After passing through the cooler 43 and the second intermediate effect filter 44, it is used to communicate with the other end of the room. The other end of the second blower 42, the temperature reduction region 13, the third heater 45, the desorption region 12 and the second regeneration fan 46 are sequentially communicated. The air treatment system having the dehumidification and sulfur removal functions described in this embodiment further includes a second air valve 51, a second initial effect filter 52 and a second front surface cooler 53. The second air valve 51, the second initial effect filter 52, the second front surface cooler 53 and the other end of the second middle surface cooler are sequentially communicated.

[0022] Specifically, in the air treatment system with dehumidification and sulfur removal functions described in this embodiment, outdoor air enters the system through the second air valve 51, and after impurities are removed by the second initial effect filter 52, the temperature is adjusted by the second front surface cooler 53, and then it flows into the second intermediate surface cooler 41 to further stabilize the temperature. After that, it is conveyed to the adsorption area 11 of the multifunctional rotating wheel 1 by the second blower 42. The dehumidification module and sulfur removal module in the adsorption area 11 simultaneously complete the adsorption treatment of water vapor and hydrogen sulfide. The treated air returns to the room after temperature adjustment by the second rear surface cooler 43 and purification by the second intermediate effect filter 44. At the same time, the other end of the second intermediate surface cooler 41 is connected to the return air of the room, so that a mixing treatment can be realized. In the regeneration cycle, the second blower 42 separates a part of the airflow, and this airflow first flows through the temperature reduction area 13 newly added to the multifunctional rotating wheel 1, pre-cools the airflow about to enter the regeneration stage, and avoids the high-temperature airflow directly colliding with the adsorption area 11 and affecting the treatment effect. Then, the airflow is heated by the third heater 45, introduced into the desorption area 12 of the multifunctional rotating wheel 1, desorbs the adsorbed water vapor and hydrogen sulfide, and is finally discharged by the second regeneration fan 46.

[0023] The newly added temperature reduction area 13 in the multifunctional rotating wheel 1 of this embodiment effectively optimizes the temperature gradient of the regeneration airflow, avoids the interference of the regeneration high temperature on the real-time treatment effect of the adsorption area 11, does not affect each other during the adsorption and regeneration processes, and improves the operation stability of the system.

[0025] Specifically, in the air treatment system having dehumidification and sulfur removal functions described in this embodiment, outside air is pre-treated by a second air valve 51, a second initial effect filter 52, and a second front surface cooler 53. The air then first flows into the second dehumidification region 61 of a newly added second dehumidifying rotating wheel 6 for primary dehumidification, removing most of the water vapor from the air. After that, the airflow enters the second intermediate surface cooler 41 for temperature adjustment and is further transported by the second blower 42 to the adsorption region 11 of the multi-functional rotating wheel 1, where the removal of remaining water vapor and adsorption of hydrogen sulfide are completed. The treated air then passes through the second rear surface cooler 43 and the second intermediate effect filter 44 before being returned to the room. In the regeneration cycle, the second regeneration fan 46 extracts airflow, which first flows through the attachment / detachment area 12 of the multi-functional rotating wheel 1, performing deep attachment / detachment to the dehumidification module and sulfur removal module in the adsorption area 11. Subsequently, the airflow is heated to a higher temperature by the fourth heater 7 and introduced into the second regeneration area 62 of the second dehumidification rotating wheel 6, performing initial regeneration on the adsorption material of the second dehumidification rotating wheel 6.

[0026] In Example 4, as can be seen from Figure 4, unlike Example 3, the air treatment system having dehumidification and sulfur removal functions described in this example further comprises a heat exchanger 8, which is provided between the fourth heater 7 and the decomposition region 12.

[0027] Specifically, in the air treatment system having dehumidification and sulfur removal functions described in this embodiment, outside air is pre-treated by a second air valve 51, a second initial effect filter 52, and a second front surface cooler 53. It then flows first into the second dehumidification region 61 of a newly added second dehumidifying rotating wheel 6 for primary dehumidification, removing most of the water vapor from the air. After that, the airflow enters the second intermediate surface cooler 41 for temperature adjustment and is further transported by the second blower 42 to the adsorption region 11 of the multi-functional rotating wheel 1, where the removal of remaining water vapor and adsorption of hydrogen sulfide are completed. The treated air then passes through the second rear surface cooler 43 and the second intermediate effect filter 44 before being returned to the room. In the regeneration cycle, the second regeneration fan 46 extracts airflow, which first flows through the desorption region 12 of the multi-functional rotating wheel 1, performing deep desorption on the dehumidification module and sulfur removal module in the adsorption region 11. Subsequently, the airflow enters the heat exchanger 8 for residual heat recovery. After that, the airflow is heated to a higher temperature by the fourth heater 7 and introduced into the second regeneration region 62 of the second dehumidification rotating wheel 6, performing initial regeneration on the adsorbent of the second dehumidification rotating wheel 6.
