Detailed implementation manners

[0029] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and steps, can be combined in any manner.

[0030] A multi-purpose air treatment device based on a four-zone adsorption wheel of the present invention includes a runner frame, a runner body, a regeneration fan, a circulation fan, a heating box, and a filter box;

[0031] The runner body is arranged in a honeycomb adsorption form, and the runner frame adopts a four-zone structure, specifically including a regeneration zone, a cooling zone, an air supply zone, and a treatment zone. Among them, the cooling zone can be used as the air supply zone, and the air supply zone can also be used as the cooling zone; the runner body is supported on the runner frame, and the regeneration fan, the circulation fan, the heating box, and the filter box are all fixed on the runner frame and are corresponding to the position of the runner body;

[0032] The rotating wheel frames are connected by connecting rods. By changing the length of the connecting rods, it can be used for rotating wheel bodies with different axial lengths. The rotating wheel body, the regeneration fan, the circulation fan, the heating box, and the filter box are connected to the rotating wheel frame by bolts;

[0033] Process partition air ducts are provided on the rotating wheel frame, and the process partition air ducts are connected to the process treatment fan for corresponding process treatment of air. An air flow regulating valve is provided on the process treatment fan to facilitate the regulation of the air flow;

[0034] The front end of the rotating wheel frame forms a front-end treatment section, and the rear end of the rotating wheel frame forms a rear-end treatment section. The air to be treated enters through the front-end treatment section or the rear-end treatment section.

[0035] At the inlet and outlet ends of the three process partitions of the regeneration area, cooling area, and make-up air area of the rotating wheel frame, different external connecting air ducts are attached and equipped with corresponding process devices such as circulation fans, air valves, filters, and heat exchangers, which can build a variety of air treatment devices that can meet different process requirements, reduce energy consumption, and enhance the desorption efficiency.

[0036] Such as Figures 1 - 8 shown,

[0037] When in the conventional air component adsorption function: The air to be treated is desorbed through the treatment section, and another path of air is heated and then enters the regeneration area for the regeneration and desorption of the adsorbed substances; ( Figure 1 )

[0038] When in the function of using the regeneration air to cool down: Use a part of the regeneration air for desorption and then cooling of the rotating wheel, reduce the temperature rise of the adsorbed air affected by the heat storage of the rotating wheel, absorb the heat storage of the rotating wheel to increase the temperature of the regeneration air, reduce the heating power, and reduce the component content of the regeneration air to improve the desorption efficiency; ( Figure 2 )

[0039] When in the regeneration air pretreatment function: All or most of the regeneration air passes through two independent partitions of the rotating wheel for pretreatment, further reducing the component content of the regeneration air, absorbing the heat storage of the rotating wheel to increase the temperature of the regeneration air, reducing the heating power, and improving the desorption efficiency; ( Figure 3 )

[0040] When in the deep regeneration and desorption function: The regeneration air and the treated air are first pretreated together to reduce the components, and then the regeneration air passes through two independent partitions of the rotating wheel for pretreatment, absorbs the heat storage of the rotating wheel to increase the temperature of the regeneration air, reduces the heating power, and then is reheated to the required temperature for thorough regeneration and desorption of the rotating wheel, meeting the extremely low limit adsorption requirements for the treated air. ( Figure 4 )

[0041] It also includes a function expansion part. When the present invention is applied under the low-limit condition of the rotating wheel, by adding an air duct from the waste discharge port to the front of the inlet of the regeneration heater outside, a part of the waste air is mixed in to increase the air temperature before regeneration heating and reduce the heating energy consumption;( Figure 5 )

[0042] Between the adsorption and desorption areas of the rotating wheel of the present invention, by adding an air duct that forms a closed loop between the two independent areas and a fan that maintains the internal air circulation outside, the heat storage of the rotating wheel after regeneration desorption is transferred to the position where the air entering the desorption area will be, preheating the adsorption material, shortening the desorption time and reducing the heating energy consumption.( Figure 6 )

[0043] The present invention utilizes the waste air after the desorption of the rotating wheel. By adding a suitable heat exchanger and a connecting air duct, heat exchange is carried out with the regeneration air that has not been heated yet, reducing the regeneration heating power;( Figure 7 )

[0044] The present invention utilizes two independent areas between the adsorption and desorption areas of the rotating wheel to form a component isolation between the adsorption and desorption air. Various purification function devices are added to the off-machine circulation loop to reduce or eliminate the component cross-contamination between the adsorption and desorption air.( Figure 8 )

[0045] In addition, the air flow adjustment means of the honeycomb adsorption type rotating wheel includes but is not limited to air duct valve adjustment and fan speed adjustment; the flow monitoring measures include but are not limited to air flow meter monitoring and pressure sensor monitoring.

[0046] In addition, the proportion of the mixed waste air can be adjusted by an air duct valve, the flow rate of the circulating air during the heat storage preheating process of the rotating wheel can be adjusted by the fan speed, and the heat exchange parameters of the heat exchanger during the heat exchange process can be adjusted according to the temperature changes of the waste air and the regeneration air.

[0047] Example 1

[0048] Conventional air component adsorption and rotating wheel adsorption function regeneration operation (two-zone)

[0049] As Figures 9 - 11 shown, the present invention connects the air to be treated to the front-end treatment section, and outputs it from the back-end treatment section after being adsorbed by the rotating wheel; at the same time, the heating box is started to heat and then the rotating wheel is regenerated and desorbed through the regeneration area; through the air flow adjustment means of the adjustment device, it is ensured that the regeneration air after adsorption and regeneration desorption is discharged by the fan and the air flow rate during the regeneration process is stable, and it is monitored in real time by the flow monitoring measures and adjusted as needed; the four zones of the device only make functional divisions of the treatment zone and the regeneration zone, and the cooling zone and the makeup air zone are incorporated into the treatment zone or the regeneration zone according to the process requirements.

[0050] Example 2

[0051] Cooling operation of the rotating wheel after desorption using regenerated air (outside air intake with three-zone shunt)

[0052] As Figures 12 - 14 shown, during the regeneration of the rotating wheel, according to the actual situation, adjust the valves of the air intake duct, and adjust one path of ambient air to enter the regeneration area directly after direct heating; the other path of ambient air passes through the desorption in the cooling area and cools the rotating wheel and then enters the regeneration area after reheating. The mixing ratio of the two paths of regenerated air is determined by adjusting the valves of the air intake duct; at the same time, monitor the changes in the temperature, temperature and component content of the air after adsorption, and ensure the best cooling and performance improvement effects; the four zones of the device are used as the treatment zone and the regeneration zone, the functional division of the cooling zone, and the make-up air zone is incorporated into the treatment zone or the regeneration zone according to the process requirements.

[0053] Example 3

[0054] Pretreatment operation of regenerated air (make-up air outside the four zones)

[0055] As Figures 15 - 18 shown, open the corresponding air duct passage, so that all or most of the regenerated air introduced by ambient air first passes through the treatment of the rotating wheel in the cooling zone and the make-up air zone, and then enters the regeneration zone through the heating box for regeneration desorption of the rotating wheel after being heated by the heating box. Monitor the changes in the component content of the regenerated air, and dynamically adjust the operating parameters of the rotating wheel (such as rotation speed, adsorption time, etc.) to ensure that the component content of the regenerated air is reduced to an ideal level and improve the desorption efficiency.

[0056] Example 4

[0057] Deep regeneration desorption operation (make-up air inside the four zones)

[0058] As Figures 19 - 21 shown, introduce the air to be treated with reduced components after introducing the front-end treated air into the pretreatment system into the cooling zone and the make-up air zone for treatment by the rotating wheel as the inlet of the heating box, and then enter the regeneration zone after being heated by the heating box to conduct thorough regeneration desorption of the rotating wheel. Strictly control the parameters such as temperature, component content and air flow rate in each link to meet the adsorption requirements for the extremely low limit of the treated air.

[0059] Example 5

[0060] As Figures 22 - 24 shown, energy-saving operation of mixing waste exhaust air (device body plus additional component 1: three-zone - exhaust air reflux)

[0061] When the rotating wheel is applied under the low-limit conditions of the three zones, detect the temperature and component content of the waste exhaust air. If the regeneration conditions are met, install a three-way regulating valve at the waste exhaust port, install an external air duct, and introduce part of the high-temperature waste exhaust air to the inlet of the heating box to be mixed with the regenerated air. The regulating valve at the waste exhaust port controls the proportion of the mixed waste exhaust air; at the same time, monitor the changes in the air temperature before regeneration heating and the heating energy consumption, and adjust timely.

[0062] Example VI

[0063] Mixing waste exhaust air, wheel heat storage preheating (device body plus additional component 2-1: four-zone - side opening closed cycle) (device body plus additional component 2-2: four-zone - top opening closed cycle)

[0064] As Figures 25 - 32 shown, closed-loop air ducts are attached and installed at the inlet and outlet ends of the three process zones of the wheel frame regeneration zone, cooling zone, and make-up air zone, and the circulation fan is started. The fan speed is adjusted to control the circulating air flow, so as to preheat the adsorption material entering the desorption area; monitor the preheating temperature of the adsorption material, desorption time, and changes in heating energy consumption, and optimize the operating parameters.

[0065] Example VII

[0066] Heat exchange energy-saving operation (device body plus additional component 3: two-zone - exhaust heat recovery)

[0067] As Figures 33 - 35 shown, a heat exchanger is installed at the regenerated air inlet. The exhaust port of the regenerated air fan is connected to the second port of the heat exchanger between the exhaust waste air pipe. The other two ports of the heat exchanger are connected to the regenerated air inlet and the connecting air duct, and the other end of the connecting air duct is connected to the inlet of the heating box. During operation, monitor the temperature changes of the exhaust waste air and the regenerated air, adjust the heat exchange parameters of the heat exchanger, minimize the regenerative heating power to the greatest extent on the premise of meeting the desorption temperature, and regularly maintain the heat exchanger to ensure the heat exchange effect.

[0068] Example VIII

[0069] Isolation of component pollution operation (device body plus additional component 4-1: four-zone - side opening filtration closed cycle) (device body plus additional component 4-2: four-zone - top opening filtration closed cycle)

[0070] As Figures 36 - 43 shown, closed-loop air ducts are attached and installed at the inlet and outlet ends of the three process zones of the wheel frame regeneration zone, cooling zone, and make-up air zone, and the circulation fan is started. An isolation barrier is formed by using the independent area between the adsorption and desorption areas of the wheel. According to the purification requirements, purification devices (such as filters, purifiers, etc.) are installed in the external circulation loop; monitor the changes in the components of the adsorption and desorption air to ensure effective reduction or elimination of component cross-contamination.

[0071] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
