Description

Technical Field

[0001] This utility model relates to the field of dust collectors, and in particular to a dehumidification and cooling device and a dust collector. Background Technology

[0002] In traditional air handling technology, dust collectors are typically used to remove particulate pollutants from the air to meet environmental emission requirements. However, traditional dust collectors have the following drawbacks: when used in high-humidity and high-temperature dust collection environments, the air after dust collection generally has high temperature and humidity, and cannot achieve the desired dehumidification and cooling effect. Utility Model Content

[0003] Therefore, it is necessary to provide a dehumidification and cooling device and a dust collector to address the problem that traditional dust collectors, when used in high humidity and high temperature dust removal environments, generally produce air with high temperature and humidity after dust removal, thus failing to achieve the desired dehumidification and cooling effect.

[0004] A dehumidification and cooling device includes: a housing assembly having a first receiving cavity and a second receiving cavity, the housing assembly having an air inlet communicating with the first receiving cavity and an air outlet communicating with the second receiving cavity; a dehumidifying surface cooler assembly disposed on the housing assembly and located within the first receiving cavity; a cooling surface cooler assembly disposed on the housing assembly and located within the second receiving cavity; and an air compressor assembly disposed on the housing assembly, the input end of the air compressor assembly communicating with the first receiving cavity and the output end of the air compressor assembly communicating with the second receiving cavity.

[0005] The first aspect of this application discloses a dehumidification and cooling device. A dehumidifying surface cooler assembly is located within a first receiving cavity, which is connected to an air inlet. Air entering from the inlet first passes over the surface of the dehumidifying surface cooler assembly, whose surface temperature is precisely controlled below the air dew point temperature. As the air flows through, water vapor in the air condenses on the surface of the dehumidifying surface cooler assembly, achieving dehumidification. Simultaneously, the air temperature decreases due to heat exchange. An air compressor assembly is connected to the first and second receiving cavities via its input and output ends, respectively. This allows the air compressor assembly to draw in dehumidified, dry air, pressurize it, and deliver it to the second receiving cavity, where it is then discharged under pressure. This process causes the air temperature to rise. A cooling surface cooler assembly is located within the second receiving cavity. Pressurized air flows over the surface of the cooling surface cooler assembly, further cooling the air to a suitable discharge temperature. Refrigerants required to reach the corresponding temperatures on their surfaces circulate inside both the dehumidifying and cooling surface cooler assemblies. The dehumidification and cooling device of this application can stably output air with both temperature and humidity meeting the standards, and has good practicality.

[0006] In one embodiment, the housing assembly has a third receiving cavity, which is connected to both the air inlet and the first receiving cavity. The housing assembly also has a first opening, which is connected to the third receiving cavity. The dehumidifier assembly closes the first opening. Because the third receiving cavity is connected to both the air inlet and the first receiving cavity, air entering from the air inlet first enters the third receiving cavity. By closing the first opening with the dehumidifier assembly, the surface of the dehumidifier assembly can fully contact the air in the third receiving cavity, thereby dehumidifying the air in the third receiving cavity. This results in good dehumidification, ensuring that the airflow entering the first receiving cavity has lower humidity and higher dryness. Furthermore, the dehumidifier continues to dehumidify the air after it enters the first receiving cavity, maintaining a high dehumidification effect.

[0007] In one embodiment, the housing assembly has a second opening communicating with the first receiving cavity, and the cooling surface cooler assembly closes the second opening. By closing the second opening with the cooling surface cooler assembly, the surface of the cooling surface cooler assembly completely covers the second opening and is directly exposed to the airflow within the first receiving cavity. This design further cools the air in the first receiving cavity, and the cooling surface cooler assembly further cools the air after it enters the second receiving cavity via the air compressor, ensuring that all surfaces of the cooling surface cooler can cool the air, resulting in excellent cooling performance.

[0008] In one embodiment, the housing assembly includes a first housing structure and a second housing structure. The first housing structure has an air inlet, a first receiving cavity, and a second receiving cavity. The first housing structure also has a third receiving cavity, which communicates with both the air inlet and the first receiving cavity. The second housing structure is mounted on the first housing structure and has an air outlet. Air entering from the air inlet first flows into the third receiving cavity of the first housing structure, where it undergoes dehumidification through contact with the dehumidifier assembly. Then, it enters the first receiving cavity of the first housing structure for further dehumidification. Subsequently, after being processed by the air compressor assembly, it undergoes cooling in the second receiving cavity of the first housing structure. This design is reasonable and ensures smooth dehumidification and cooling, ultimately discharging the air from the air outlet of the second housing structure.

[0009] In one embodiment, the first housing structure includes a first outer shell, a first supporting shell, and a second supporting shell. The first outer shell has the air inlet. Both the first and second supporting shells are disposed on the first outer shell and located inside it. The first supporting shell and the first outer shell together form the third receiving cavity. The first supporting shell, the second supporting shell, and the first outer shell together form the first receiving cavity, and the second supporting shell together with the first outer shell form the second receiving cavity. The arrangement of the first outer shell, the first supporting shell, and the second supporting shell separates and forms a closed first receiving cavity, a second receiving cavity, and a third receiving cavity, thereby enabling stable dehumidification and cooling operations and preventing humidity rebound caused by the mixing of dry airflow and undehumidified air.

[0010] In one embodiment, the first support shell has a first opening that communicates with the third receiving cavity. The dehumidifier assembly is disposed on the first support shell and closes the first opening. By closing the first opening with the dehumidifier assembly, the surface of the dehumidifier assembly can come into contact with the air in the third receiving cavity, thereby dehumidifying the air in the third receiving cavity and improving the dehumidification effect.

[0011] In one embodiment, the second support shell has a second opening that communicates with the first receiving cavity. The cooling surface cooler assembly is disposed on the second support shell and closes the second opening. By closing the second opening with the cooling surface cooler assembly, the surface of the cooling surface cooler assembly can come into contact with the air in the first receiving cavity, thereby dehumidifying the air in the first receiving cavity and improving the dehumidification effect.

[0012] In one embodiment, a mating cover is further included. The mating cover is disposed on the first supporting shell or the dehumidifier assembly. The mating cover is located within the third receiving cavity. The side of the dehumidifier assembly facing the third receiving cavity is enclosed by the mating cover to form a dehumidification space. The mating cover is provided with flow holes, which communicate with both the third receiving cavity and the dehumidification space. Through the flow holes communicating with both the third receiving cavity and the dehumidification space, air from the third receiving cavity can enter the dehumidification space. Since the surface temperature of the dehumidifier assembly is lower than the air dew point temperature, the air in the dehumidification space can achieve full and sufficient contact with the surface of the dehumidifier assembly, thus achieving a dehumidification effect.

[0013] In one embodiment, the second housing structure includes a filter chamber connected to both the second receiving cavity and the air outlet. It also includes a filter assembly disposed on the second housing structure and located within the filter chamber. The filter assembly allows for further filtration of air entering the filter chamber after the temperature and humidity meet the requirements. This ensures that the air ultimately discharged from the air outlet not only meets the temperature and humidity requirements but also possesses improved cleanliness, comprehensively optimizing the output air quality and meeting higher standards for use or emissions. The filter assembly can be a filter screen, etc.

[0014] In one embodiment, the second housing structure includes a second outer shell and a support member. The second outer shell has the filter chamber and the air outlet. The support member is disposed on the second outer shell and located within the filter chamber. The filter assembly is disposed on the support member. By placing the filter assembly on the support member, the position of the filter assembly is stabilized. This design prevents the filter assembly from shifting or shaking due to airflow impact when air flows within the filter chamber, ensuring that the filter assembly can continuously and stably intercept residual impurities in the air after it enters the filter chamber.

[0015] In one embodiment, the housing assembly has an assembly hole communicating with the air outlet, and also includes a concentration sensor mounted on the housing assembly at the assembly hole. Positioning the concentration sensor at the assembly hole ensures stable installation and reliable monitoring. The concentration sensor detects air concentration, ensuring emissions meet standards and improving reliability.

[0016] A dust collector includes: the aforementioned dehumidification and cooling device.

[0017] The second aspect of this application discloses a dust collector that complements the dust removal function of the aforementioned dehumidification and cooling device by combining its dehumidification, cooling, filtration, and concentration monitoring functions. This allows the dust collector to not only remove dust from the air but also simultaneously address issues such as excessive humidity, abnormal temperature, and excessive concentration in the air after dust removal, thus avoiding the shortcomings of traditional dust collectors that can only remove dust but cannot simultaneously ensure that the air temperature, humidity, and concentration meet the standards.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0041] Example 1

[0042] like Figure 1-15 As shown, this embodiment discloses a dehumidification and cooling device, comprising: a housing assembly 1, wherein the housing assembly 1 is provided with a first receiving cavity 101 and a second receiving cavity 102, the housing assembly 1 is provided with an air inlet 103 communicating with the first receiving cavity 101, and the housing assembly 1 is provided with an air outlet 104 communicating with the second receiving cavity 102; a dehumidifying surface cooler assembly 2, wherein the dehumidifying surface cooler assembly 2 is disposed on the housing assembly 1 and located within the first receiving cavity 101; a cooling surface cooler assembly 3, wherein the cooling surface cooler assembly 3 is disposed on the housing assembly 1 and located within the second receiving cavity 102; and an air compressor assembly 4, wherein the air compressor assembly 4 is disposed on the housing assembly 1, the input end of the air compressor assembly 4 communicating with the first receiving cavity 101, and the output end of the air compressor assembly 4 communicating with the second receiving cavity 102.

[0043] The first aspect of this application discloses a dehumidification and cooling device. A dehumidifier surface cooler assembly 2 is located within a first receiving cavity 101, which is connected to an air inlet 103. Air entering from the air inlet 103 first passes over the surface of the dehumidifier surface cooler assembly 2. The surface temperature of the dehumidifier surface cooler assembly 2 is precisely controlled below the air dew point temperature. As air flows through, water vapor in the air condenses into water on the surface of the dehumidifier surface cooler assembly 2, achieving dehumidification. Simultaneously, the air temperature decreases due to heat exchange. An air compressor assembly 4 is connected to the first receiving cavity 101 and a second receiving cavity 102 via its input and output ends, respectively. This allows the air compressor assembly 4 to draw in dehumidified, dry air, pressurize it, and deliver it to the second receiving cavity 102, where it is then discharged under pressure. This process causes the air temperature to rise. The cooling surface cooler assembly 3 is located within the second receiving cavity 102. Pressurized air flows over the surface of the cooling surface cooler assembly 3, further cooling the air to a suitable discharge temperature. Refrigerants required to reach the corresponding temperature on their surfaces circulate inside both the dehumidifying surface cooler assembly 2 and the cooling surface cooler assembly 3. The dehumidifying and cooling device of this application can stably output air with both temperature and humidity meeting standards, demonstrating good practicality.

[0044] like Figure 2-3 and Figure 7-8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a third receiving cavity 105, the third receiving cavity 105 is connected to the air inlet 103 and the first receiving cavity 101 respectively, the housing assembly 1 is provided with a first opening 106, the first opening 106 is connected to the third receiving cavity 105, and the dehumidifier surface cooler assembly 2 closes the first opening 106. Because the third receiving cavity 105 is connected to both the air inlet 103 and the first receiving cavity 101, air entering from the air inlet 103 will first enter the third receiving cavity 105. By closing the first opening 106, the surface of the dehumidifier surface cooler assembly 2 can fully contact the air in the third receiving cavity 105, thereby dehumidifying the air in the third receiving cavity 105. The dehumidification effect is good, ensuring that the airflow entering the first receiving cavity 101 has lower humidity and higher dryness. Moreover, after the air enters the first receiving cavity 101, the dehumidifier surface cooler continues to dehumidify, resulting in a good dehumidification effect.

[0045] like Figure 6-9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a second opening 107, the second opening 107 communicating with the first receiving cavity 101, and the cooling surface cooler assembly 3 sealing the second opening 107. By sealing the second opening 107 with the cooling surface cooler assembly 3, the surface of the cooling surface cooler assembly 3 completely covers the second opening 107 and is directly exposed to the airflow in the first receiving cavity 101. This design can further cool the air in the first receiving cavity 101, and after the air enters the second receiving cavity 102 through the air compressor, the cooling surface cooler assembly 3 will cool the air again, enabling all surfaces of the cooling surface cooler to cool the air, resulting in a good cooling effect.

[0046] like Figure 2 and Figure 6-8 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the housing assembly 1 includes a first housing structure 11 and a second housing structure 12, the first housing structure 11 is provided with the air inlet 103, the first receiving cavity 101 and the second receiving cavity 102, the first housing structure 11 is provided with a third receiving cavity 105, the third receiving cavity 105 is connected to the air inlet 103 and the first receiving cavity 101 respectively, the second housing structure 12 is disposed on the first housing structure 11, and the second housing structure 12 is provided with the air outlet 104. The air entering from the air inlet 103 first flows into the third receiving cavity 105 of the first housing structure 11. After dehumidification by contact with the dehumidifier surface cooler assembly 2 in the third receiving cavity 105, it enters the first receiving cavity 101 of the first housing structure 11 for further dehumidification. Subsequently, after being processed by the air compressor assembly 4, it can be cooled in the second receiving cavity 102 of the first housing structure 11. The design is reasonable and ensures the smooth implementation of dehumidification and cooling. Finally, it is discharged from the air outlet 104 of the second housing structure 12.

[0047] like Figure 3 and Figure 7-8As shown, in addition to the features of the above embodiments, this embodiment further defines: the first housing structure 11 includes a first outer shell 111, a first supporting shell 112, and a second supporting shell 113. The first outer shell 111 is provided with the air inlet 103. The first supporting shell 112 and the second supporting shell 113 are both disposed on the first outer shell 111 and are both located inside the first outer shell 111. The first supporting shell 112 and the first outer shell 111 enclose the third receiving cavity 105. The first supporting shell 112, the second supporting shell 113, and the first outer shell 111 enclose the first receiving cavity 101. The second supporting shell 113 and the first outer shell 111 enclose the second receiving cavity 102. The arrangement of the first outer shell 111, the first supporting shell 112, and the second supporting shell 113 can separate and form a closed first receiving cavity 101, a second receiving cavity 102, and a third receiving cavity 105, thereby enabling stable dehumidification and cooling operations and avoiding humidity rebound caused by the mixing of dry airflow and undehumidified air.

[0048] like Figure 7-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first support shell 112 is provided with a first opening 106, the first opening 106 communicating with the third receiving cavity 105, and the dehumidifier surface cooler assembly 2 is disposed on the first support shell 112 and closes the first opening 106. By closing the first opening 106 with the dehumidifier surface cooler assembly 2, the surface of the dehumidifier surface cooler assembly 2 can contact the air in the third receiving cavity 105, thereby dehumidifying the air in the third receiving cavity 105 and improving the dehumidification effect.

The mating cover 5 is provided with a flow hole 502, which communicates with both the third receiving cavity 105 and the dehumidification space 501. Through the flow hole 502, which communicates with both the third receiving cavity 105 and the dehumidification space 501, air from the third receiving cavity 105 can enter the dehumidification space 501. Since the surface temperature of the dehumidifier assembly 2 is lower than the air dew point temperature, the air in the dehumidification space 501 can achieve full and sufficient contact with the surface of the dehumidifier assembly 2, thus achieving a dehumidification effect.

[0051] like Figure 2 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second housing structure 12 is provided with a filter chamber 108, which is connected to the second receiving cavity 102 and the air outlet 104 respectively, and also includes a filter assembly, which is disposed on the second housing structure 12 and located within the filter chamber 108. The filter assembly allows air with acceptable temperature and humidity to enter the filter chamber 108 and undergo further filtration, ensuring that the air finally discharged from the air outlet 104 not only meets the temperature and humidity requirements but also has better cleanliness, comprehensively optimizing the output air quality and meeting higher standards for use or emissions. The filter assembly can be a filter screen, etc.

[0052] like Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further defines: the second housing structure 12 includes a second outer shell 121 and a support member 122. The second outer shell 121 is provided with the filter chamber 108 and the air outlet 104. The support member 122 is disposed on the second outer shell 121 and located within the filter chamber 108. The filter assembly is disposed on the support member 122. By disposing the filter assembly on the support member 122, the position of the filter assembly is stabilized. This design avoids displacement or shaking of the filter assembly due to airflow impact when air flows within the filter chamber 108, ensuring that the filter assembly can continuously and stably intercept residual impurities in the air after the air enters the filter chamber 108.

[0053] like Figure 6-8 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with an assembly hole 109, the assembly hole 109 is connected to the air outlet 104, and also includes a concentration sensor, which is disposed on the housing assembly 1 and located at the assembly hole 109.
