Description

Technical Field

[0001] This invention relates to the field of anti-corrosion coating construction, and in particular to a dehumidifier and dehumidification method suitable for large open spaces. Background Technology

[0002] Many environmental factors affect the quality of anti-corrosion construction, such as temperature, humidity, ventilation, dust, working at heights, and confined spaces. Among these, humidity is one of the most common and significant influencing factors. Strict humidity control is required during anti-corrosion construction; generally, the humidity level should be kept below 85%. Excessive humidity can cause various adverse effects. This is especially true for anti-corrosion construction in the nuclear power industry, where environmental control is crucial.

[0003] Currently, environmental control for corrosion prevention construction in the nuclear power field mainly involves using heated dehumidifiers for prolonged ventilation to achieve dehumidification. Heated dehumidifiers can reduce the humidity of a local space to very low levels (below 30%), meaning they provide good localized drying. However, the humidity in the air is merely evaporated by superheating, turning into "superheated steam." Without necessary measures, the superheated steam will condense and return to the original air humidity.

[0004] In existing technologies, the dehumidifying impeller is the adsorption and dehumidification component in a heated dehumidifier, composed of highly absorbent activated silica gel and glass fiber. The dehumidifying impeller is divided into a regeneration zone and a treatment zone. Moist air exits the dehumidifying impeller after passing through the treatment zone. The airflow used for drying the impeller is heated and then passes through the regeneration zone, allowing the dehumidifying impeller to be reused and improving processing efficiency.

[0005] Feedback from on-site users indicates that heated dehumidifiers have high energy consumption, low efficiency, poor performance, and narrow applicability. When used on large-diameter pipes or inside containers, the superheated steam will restore the original air humidity due to space and ambient temperature issues.

[0006] Therefore, it is necessary to improve existing technologies and methods, and there is an urgent need to develop a small, modular anti-corrosion construction environment control device for the interior of large-diameter pipes and containers. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a dehumidifier and dehumidification method suitable for large open spaces, which is highly efficient and has low energy consumption.

[0008] This invention provides a dehumidifier suitable for large open spaces, which includes: a processing zone channel and a regeneration zone channel;

[0009] The processing zone channel and the regeneration zone channel are separated by a heat-insulating partition.

[0010] The first and second adsorption plates are movable structures, located in the processing zone channel and the regeneration zone channel, respectively; the first and second adsorption plates are not simultaneously located in the same channel.

[0011] Both the first adsorption plate and the second adsorption plate are provided with movable electrode plates;

[0012] A fixed electrode plate is provided in the regeneration zone channel; the fixed electrode plate is located on the side of the second adsorption plate near the secondary air outlet.

[0013] The airflow direction in the processing zone channel is opposite to that in the regeneration zone channel.

[0014] In one specific embodiment of the present invention, after the first adsorption plate has completely adsorbed the adsorption, it is moved into the regeneration zone channel, and at the same time the second adsorption plate is moved into the processing zone channel.

[0015] In one specific embodiment of the present invention, the first adsorption plate and the second adsorption plate are cuboids.

[0016] In one specific embodiment of the present invention, the fixed electrode plate is disposed at the secondary air outlet end or in the middle of the regeneration zone channel.

[0017] In one specific embodiment of the present invention, a fan is provided at the entrance of the processing zone channel to transport the hot and humid air entering from the processing air inlet into the channel for adsorption treatment.

[0018] A fan is installed in the regeneration zone channel to transport air entering from the secondary air inlet into the channel for desorption treatment.

[0019] In one specific embodiment of the present invention, the fixed electrode plate and the movable electrode plate are connected to a high-voltage electric field power supply.

[0020] This invention provides a dehumidification method using a dehumidifier suitable for large open spaces as described above, comprising the following steps:

[0021] Step 1: The first adsorption plate adsorbs water vapor from the humid air entering the processing zone channel;

[0022] Step 2: After the first adsorption plate has completely adsorbed the water vapor, it is moved to the regeneration zone channel and desorbed using dry air; at the same time, the second adsorption plate is moved to the treatment zone channel to perform water vapor adsorption treatment.

[0023] Step 3: After the water vapor is completely desorbed from the first adsorption plate, the positions of the first adsorption plate and the second adsorption plate are switched; the second adsorption plate is moved into the regeneration zone channel for water vapor desorption treatment; the first adsorption plate is moved into the treatment zone channel to perform water vapor adsorption treatment.

[0024] Step 4: Return to Step 2.

[0025] In a specific embodiment of the present invention, during step 2, when the water vapor desorption process is performed, a high-voltage electric field power supply is used to energize the fixed electrode plate and the movable electrode plate set on the first adsorption plate. After the high-voltage electric field is established, the water vapor on the first adsorption plate migrates and desorbs towards the positive electrode of the electric field and is discharged with the dry air.

[0026] In a specific embodiment of the present invention, when dry air passes through a secondary air inlet, a second adsorption plate, and a fixed electrode plate in sequence, a movable electrode plate is provided on the second adsorption plate; the fixed electrode plate is connected to the positive terminal of the power supply, and the movable electrode plate is connected to the negative terminal of the power supply; after a high-voltage electric field is established by powering on, the water vapor in the second adsorption plate will migrate and desorb towards the positive terminal of the electric field and be discharged with the air.

[0027] When dry air passes through the secondary air inlet, the first adsorption plate, and the fixed electrode plate in sequence, a movable electrode plate is set on the first adsorption plate; the fixed electrode plate is connected to the positive terminal of the power supply, and the movable electrode plate is connected to the negative terminal of the power supply; after the high voltage electric field is established by powering on, the water vapor in the first adsorption plate will migrate and desorb towards the positive terminal of the electric field and be discharged with the air.

[0028] In a specific embodiment of the present invention, when dry air passes through a secondary air inlet, a second adsorption plate, and a fixed electrode plate in sequence, a movable electrode plate is provided on the second adsorption plate; the fixed electrode plate is connected to the positive terminal of the power supply, and the movable electrode plate is connected to the negative terminal of the power supply; after a high-voltage electric field is established by powering on, the water vapor in the second adsorption plate will migrate and desorb towards the positive terminal of the electric field and be discharged with the air.

[0029] When dry air passes through the secondary air inlet, fixed electrode plate, and first adsorption electrode plate in sequence, a movable electrode plate is set on the first adsorption plate; the fixed electrode plate is connected to the negative terminal of the power supply, and the movable electrode plate is connected to the positive terminal of the power supply; after the high voltage electric field is established by powering on, the water vapor in the first adsorption plate will migrate and desorb towards the positive terminal of the electric field and be discharged with the air.

[0030] Compared with the prior art, the dehumidifier and dehumidification method of the present invention, which are suitable for large open spaces, have the following beneficial effects:

[0031] (1) By improving the internal structure of the dehumidifier, the processing zone and the regeneration zone can work independently, avoiding the temperature influence between the two. There is no waiting time during the processing of the two zones, saving processing time and improving dehumidification efficiency; it fits the characteristics of the short overhaul window of nuclear power plants and is suitable for anti-corrosion coating construction in the nuclear power industry.

[0032] (2) The two adsorption plates simultaneously adsorb water vapor and desorb it by switching, which reduces the desorption time and improves the regeneration efficiency.

[0033] (3) The high-voltage electric field method for water vapor desorption is much more efficient than the high-temperature method. Moreover, the high-voltage electric field method for water vapor desorption greatly reduces the temperature of the adsorption material and the treatment zone channel. The water vapor adsorption capacity of the adsorption plate after treatment by this method is effectively maintained.

[0034] (4) The overall energy consumption was reduced by using the high voltage electric field method for water vapor desorption.

[0035] Verification has shown that the dehumidification efficiency of this invention is more than 5 times that of a rotary dehumidifier, and its overall energy consumption is 30% lower than that of a rotary dehumidifier. Attached Figure Description

Detailed Implementation

[0040] To further understand the present invention, embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, and not for limiting the present invention.

[0041] like Figures 1-2 As shown, the structure of an existing dehumidifier specifically includes:

[0042] Dehumidifying impeller 2 is the adsorption and dehumidification component in the dehumidifier, composed of highly absorbent active silica gel and glass fiber. Dehumidifying impeller 2 efficiently absorbs and retains water vapor.

[0043] The dehumidifying rotor 2 is divided into two zones: a regeneration zone 10 and a processing zone 11. Humid air enters through the dehumidifying air inlet 8, is transported to the dehumidifying rotor 2 by the dehumidifying fan 4, passes through the processing zone 11 of the dehumidifying rotor 2, and then exits as dry air through the dehumidifying air outlet 9. Because the dehumidifying rotor 2 rotates slowly, the incoming air always encounters the dry areas on the rotor 2, thus creating a continuous dehumidification process.

[0044] When a large amount of water vapor is adsorbed inside the dehumidifying impeller 2, the regeneration of the dehumidifying impeller 2 is started. The regeneration air for drying enters through the regeneration air inlet 7 and is heated by the regeneration heater 3. The regeneration air passes through the dehumidifying impeller 2 in the opposite direction to the humid air, carrying away the water vapor adsorbed on the dehumidifying impeller 2. The regeneration fan 1 transports the humid air to the regeneration air outlet 6 for discharge.

[0045] The efficiency of a dehumidifier depends on the water vapor adsorption rate in the treatment zone 11, the water vapor removal rate in the regeneration zone 10, and the cooling rate in the regeneration zone 10. In actual use, it mainly depends on the water vapor desorption and cooling rates in the regeneration zone 10.

[0046] The regeneration zone 10 and the treatment zone 11 are separated by a bent partition plate 12. Since the regeneration zone 10 and the treatment zone 11 are on the same dehumidification rotor 2, the high temperature of the regeneration zone 10, which drives away water vapor, will be transferred to the treatment zone 11, thereby reducing the adsorption capacity of the treatment zone 11 for water vapor and reducing the dehumidification efficiency of the dehumidifier.

[0047] After the regeneration zone 10 removes water vapor, the zone has a high temperature of about 100°C. The dehumidifying wheel 2 rotates slowly under the action of the reducer 5. The high temperature area of ​​the dehumidifying wheel 2 rotates to the treatment zone 11. Only after cooling can it effectively adsorb water vapor. That is, within a certain period of time, some wheels in the treatment zone 11 cannot immediately participate in water vapor adsorption. This situation further reduces the overall dehumidification efficiency of the dehumidifier.

[0048] Embodiments of the present invention disclose a dehumidifier suitable for large open spaces, such as... Figure 3 As shown, its interior includes:

[0049] Processing area channel 13, regeneration area channel 14;

[0050] The processing zone channel 13 and the regeneration zone channel 14 are separated by a heat insulation plate 15 to avoid temperature interference between the two.

[0051] The first adsorption plate 20 and the second adsorption plate 21 are movable structures, located in the processing zone channel 13 and the regeneration zone channel 14 respectively; the first adsorption plate 20 and the second adsorption plate 21 are not located in the same channel at the same time.

[0052] The first adsorption plate 20 and the second adsorption plate 21 are cuboids;

[0053] After the first adsorption plate 20 has completely adsorbed the adsorption, it is moved horizontally into the regeneration zone channel 14, while the second adsorption plate 21 is moved horizontally into the treatment zone channel.

[0054] Both the first adsorption plate 20 and the second adsorption plate 21 are provided with movable electrode plates 24;

[0055] A fixed electrode plate 23 is provided in the regeneration zone channel 14;

[0056] The fixed electrode plate 23 is disposed at the secondary air outlet 19 end in the regeneration zone channel 14, or in the middle of the regeneration zone channel 14.

[0057] Preferably, the fixed electrode plate 23 is located in the middle of the regeneration zone channel 14, with a first adsorption plate 20 on one side and a second adsorption plate 21 on the other side;

[0058] The high-voltage electric field power supply 22 is connected to the fixed electrode plate 23 and the movable electrode plate 24 respectively;

[0059] A fan is installed at the entrance of the processing area channel 13 to transport the hot and humid air entering through the processing air inlet 16 into the channel for adsorption treatment.

[0060] A fan is installed in the regeneration zone channel 14 to transport the air entering from the secondary air inlet 18 into the channel for desorption treatment.

[0061] The airflow direction in the processing zone channel 13 is opposite to that in the regeneration zone channel 14.

[0062] An embodiment of the present invention discloses a dehumidification method suitable for large open spaces, comprising the following steps:

[0063] Step 1: The first adsorption plate 20 adsorbs water vapor from the humid air entering the processing zone channel 13.

[0064] Step 2: After the first adsorption plate 20 has completely adsorbed the water vapor, it is moved to the regeneration zone channel 14 and desorbed by dry air; at the same time, the second adsorption plate 21 is moved to the treatment zone channel 13 to perform water vapor adsorption treatment.

[0065] During the water vapor desorption process, the high-voltage electric field power supply 22 is used to energize the fixed electrode plate 23 and the movable electrode plate 24 set on the first adsorption plate 20. After the high-voltage electric field is established, the water vapor on the first adsorption plate 20 migrates and desorbs towards the positive electrode of the electric field and is discharged with the dry air.

[0066] Step 3: After the water vapor is completely desorbed from the first adsorption plate 20, the positions of the first adsorption plate 20 and the second adsorption plate 21 are switched; the second adsorption plate 21 is moved into the regeneration zone channel 14 for water vapor desorption treatment; the first adsorption plate 20 is moved into the treatment zone channel 13 to perform water vapor adsorption treatment.

[0067] Step 4: Return to Step 2.

[0068] Specifically, when dry air passes through the secondary air inlet 18, the second adsorption plate 21, and the fixed electrode plate 23 in sequence, a movable electrode plate 24 is provided on the second adsorption plate 21; the fixed electrode plate 23 is connected to the positive terminal of the power supply, and the movable electrode plate 24 is connected to the negative terminal of the power supply; after the high voltage electric field is established by powering on, the water vapor in the second adsorption plate 21 will migrate and desorb towards the positive terminal of the electric field and be discharged with the air.

[0069] When dry air passes through the secondary air inlet 18, the first adsorption plate 20, and the fixed electrode plate 23 in sequence, a movable electrode plate 24 is provided on the first adsorption plate 20; the fixed electrode plate 23 is connected to the positive terminal of the power supply, and the movable electrode plate 24 is connected to the negative terminal of the power supply; after the high voltage electric field is established by powering on, the water vapor in the first adsorption plate 20 will migrate and desorb towards the positive terminal of the electric field and be discharged with the air.

[0070] Alternatively, when dry air passes through the secondary air inlet 18, fixed electrode plate 23, and first adsorption electrode plate 20 in sequence, a movable electrode plate 24 is provided on the first adsorption plate 20; the fixed electrode plate 23 is connected to the negative terminal of the power supply, and the movable electrode plate 24 is connected to the positive terminal of the power supply; after the high voltage electric field is established by powering on, the water vapor in the first adsorption plate 20 will migrate and desorb towards the positive terminal of the electric field and be discharged with the air.

[0071] The high-voltage electric field is at least twice as effective at removing water vapor as the high-temperature method, and its overall energy consumption is less than 30% of that of the high-temperature method.

[0072] To further understand the present invention, the following detailed description of the dehumidifier and dehumidification method suitable for large open spaces provided by the present invention is provided in conjunction with embodiments. The scope of protection of the present invention is not limited by the following embodiments.

[0073] Example 1

[0074] A dehumidifier suitable for large open spaces includes:

[0075] Processing area channel 13, regeneration area channel 14;

[0076] The processing zone channel 13 and the regeneration zone channel 14 are separated by a heat insulation partition 15;

[0077] The first adsorption plate 20 and the second adsorption plate 21 are movable structures, located in the processing zone channel 13 and the regeneration zone channel 14 respectively; the first adsorption plate 20 and the second adsorption plate 21 are not located in the same channel at the same time.

[0078] The first adsorption plate 20 and the second adsorption plate 21 are cuboids;

[0079] After the first adsorption plate 20 has completely adsorbed the adsorption, it is moved horizontally into the regeneration zone channel 14, while the second adsorption plate 21 is moved horizontally into the treatment zone channel.

[0080] The first adsorption plate 20 and the second adsorption plate 21 are cuboids, and their processing surfaces are rectangles with length = 2r and width = r.

[0081] Both the first adsorption plate 20 and the second adsorption plate 21 are provided with movable electrode plates 24;

[0082] A fixed electrode plate 23 is provided in the regeneration zone channel 14;

[0083] The fixed electrode plate 23 is disposed in the middle of the regeneration zone channel 14, with a first adsorption plate 20 on one side and a second adsorption plate 21 on the other side.

[0084] A fan is installed at the entrance of the processing area channel 13 to transport the hot and humid air entering through the processing air inlet 16 into the channel for adsorption treatment.

[0085] A fan is installed in the regeneration zone channel 14 to transport the air entering from the secondary air inlet 18 into the channel for desorption treatment.

[0086] The airflow direction in the processing zone channel 13 is opposite to that in the regeneration zone channel 14.

[0087] Comparative Example 1

[0088] An existing rotary dehumidifier has a circular dehumidifier rotor 2 with a radius of r. The treatment area 11 occupies one-quarter of the area of ​​the dehumidifier rotor 2, i.e., S. 11 =3π / 4r 2 The regeneration zone 10 occupies three-quarters of the dehumidification rotor area, i.e., S 10 =π / 4r 2 .

[0089] Compared with existing rotary dehumidifiers, the dehumidifier in Example 1 has a treatment area ratio of 0.85. The single-time adsorption capacity of the treatment area of ​​the dehumidifier in Example 1 is 15% lower than that of the existing rotary dehumidifier, but the adsorption saturation time per unit area is the same. That is, as long as there is continuous adsorption material for water vapor adsorption, the water vapor adsorption treatment capacity of the two methods is the same.

[0090] Compared to existing rotary dehumidifiers, the dehumidifier in Example 1 has a regeneration zone area ratio of 2.55. The desorption capacity of the regeneration zone in Example 1 is 255% of that of existing rotary dehumidifiers, and its desorption speed is also 2.55 times faster. Furthermore, in Example 1, the processing zone channel 13 and the regeneration zone channel 14 operate independently, with no heat transfer between them, thus improving the adsorption capacity of the processing zone while reducing heat loss in the regeneration zone.

It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
