Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an energy-saving air compressor air supply device. Background Technology

[0002] Cigarette manufacturers typically install multiple air compressors for air supply. Because the compressed air produced by these compressors is very hot and humid, it requires a dryer to cool and dehumidify it before use. Traditionally, one air compressor corresponds to one dryer; if the dryer malfunctions, the corresponding air compressor also becomes unusable. In summer, the high intake temperature of the air compressors can easily cause the produced compressed air to become too hot, leading to compressor overheating and malfunctions. This also increases the load on the dryer, potentially preventing it from cooling the compressed air to its dew point for dehumidification, resulting in excessively high humidity that does not meet production requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an energy-saving air compressor air supply device that utilizes the cold energy of the refrigeration unit and the cold energy of the air compressor system, which not only improves the operating efficiency and stability of the equipment, but also saves energy.

[0004] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0005] An energy-saving air compressor supply device includes multiple air compressor systems. Each air compressor system includes an air compressor, a dryer, and an air storage tank. Every two air compressor systems form a group, and the two air compressor systems within a group are connected by an electric valve. The air compressor's inlet end is equipped with an inlet filter and a cooler in sequence. The air compressor's output end is connected to the dryer through a valve and an electric valve. The dryer's output end is connected to the air storage tank through a valve. The top of the air storage tank is connected to a distribution cylinder through a valve and a pipe. The bottom of the air storage tank is equipped with a drain valve.

[0006] Preferably, the above technical solution further includes a refrigeration unit, which is connected to a water distribution cylinder via a pipe. The water distribution cylinder is connected to an air conditioner and a fan coil unit via a first valve and a second electric valve. The air conditioner and the fan coil unit are connected to a cooler via a first electric valve, a second pipe, and a valve. The cooler is connected to a water collection cylinder via a valve, a first pipe, and a third valve. The water collection cylinder is connected to the refrigeration unit via a fourth valve and a third electric valve.

[0007] Preferably, in the above technical solution, the gas cylinder is connected to the heat exchanger via the thirty-sixth valve, the seventh pipe, and the tenth valve, and the heat exchanger is connected to the gas-using equipment via the eleventh valve; the refrigeration unit is connected to the heat exchanger via the fifth valve and the ninth valve, the heat exchanger is connected to the cooling tower via the eighth valve, and the cooling tower is connected to the refrigeration unit via the seventh valve and the sixth valve.

[0008] Preferably, in the above technical solution, in the first group, when the first dryer malfunctions, the sixth electric valve is opened and the fifth electric valve is closed, and the compressed air generated by the first air compressor enters the second dryer through the fourteenth valve, the sixth electric valve, and the seventh electric valve.

[0009] Preferably, in the above technical solution, in the first group, when the second dryer malfunctions, the sixth electric valve is opened and the seventh electric valve is closed, and the compressed air generated by the second air compressor enters the first dryer through the nineteenth valve, the sixth electric valve, and the fifth electric valve.

[0010] Preferably, in the above technical solution, in the second group, when the third dryer malfunctions, the ninth electric valve is opened and the eighth electric valve is closed, and the compressed air generated by the third air compressor enters the fourth dryer through the twenty-fourth valve, the ninth electric valve, and the tenth electric valve.

[0011] Preferably, in the above technical solution, in the second group, when the fourth dryer malfunctions, the ninth electric valve is opened and the tenth electric valve is closed, and the compressed air generated by the fourth air compressor enters the third dryer through the twenty-ninth valve, the ninth electric valve, and the eighth electric valve.

[0012] The above-mentioned technical solution of this utility model has the following beneficial effects:

[0013] This application installs a cooler at the air compressor inlet, using low-quality chilled water from a refrigeration unit to exchange cooling energy with the air. This cools the air before it enters the air compressor and is compressed into compressed air, ensuring the compressed air temperature remains within a reasonable range. One air compressor and its corresponding dryer constitute one set, and two sets form a group. A bypass pipe and valve are installed between two sets of air compressors and dryers. When the dryer in one set fails, the air compressor in that set can continue operating using the dryers from other groups, thus solving the problem of air compressor malfunction caused by dryer failure. The compressed air, after dehumidification by the dryer, has a lower temperature, and the cooling energy of this low-temperature compressed air can be used to help lower the cooling water temperature of the refrigeration unit, thereby improving the refrigeration efficiency of the refrigeration unit in hot summers. Therefore, this application utilizes the cooling energy of the refrigeration unit and the air compressor system, not only improving equipment operating efficiency and stability but also saving energy.

Detailed Implementation

[0017] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0018] In this invention, the first air compressor 29, the first dryer 32, and the first air tank 35 form one set; the second air compressor 42, the second dryer 46, and the second air tank 49 form another set; these two sets of air compressor units are further combined into a group via the sixth electric valve 43. The third air compressor 56, the third dryer 59, and the third air tank 62 form one set; the fourth air compressor 69, the fourth dryer 73, and the fourth air tank 76 form another set; these two sets of air compressor units are further combined into a third group via the ninth electric valve 70.

[0019] The compressed air flow of the first set of air compressor systems in the first group is as follows: After being filtered by the first intake filter 28, the air passes through the first cooler 27. The air is cooled and absorbs heat in the first cooler 27 before entering the compressor of the first air compressor 29. The compressed air then passes through the fourteenth valve 30 and the fifth electric valve 31 into the first dryer 32 for cooling and dehumidification. After cooling and dehumidification, the compressed air exits the first dryer 32 and enters the first air storage tank 35 through the fifteenth valve 33. It then passes through the sixteenth valve 36, the third pipe 37, and the thirty-fifth valve 82 at the top of the first air storage tank 35 before entering the distribution cylinder 84. The condensate collected at the bottom of the first air storage tank 35 after being cooled by the first dryer 32 can be discharged through the first drain valve 34. The compressed air flow of the second set of air compressor systems in the first group is as follows: After being filtered by the second intake filter 41, the air passes through the second cooler 40. The air is cooled and absorbs heat in the second cooler 40 before entering the compressor of the second air compressor 42. The compressed air then passes through the nineteenth valve 45 and the seventh electric valve 44 into the second dryer 46 for cooling and dehumidification. After cooling and dehumidification, the compressed air flows out of the second dryer 46 and enters the second air storage tank 49 through the twentieth valve 47. It then passes through the twenty-first valve 50, the twenty-fourth pipe 51, and the thirty-fourth valve 81 at the top of the second air storage tank 49 before entering the distribution cylinder 84. The condensate collected at the bottom of the second air storage tank 49 after being cooled by the second dryer 46 can be discharged through the second drain valve 48. A bypass sixth electric valve 43 is installed between the first and second air compressor systems in the first group. When the first dryer 32 malfunctions, the bypass sixth electric valve 43 is opened and the fifth electric valve 31 is closed. The compressed air generated by the first air compressor 29 can then enter the second dryer 46 for cooling and dehumidification via the fourteenth valve 30, the sixth electric valve 43, and the seventh electric valve 44, thus allowing the first air compressor 29 to continue operating. Similarly, when the second dryer 46 malfunctions, the bypass sixth electric valve 43 is opened and the seventh electric valve 44 is closed. The compressed air generated by the second air compressor 42 can then enter the first dryer 32 for cooling and dehumidification via the nineteenth valve 45, the sixth electric valve 43, and the fifth electric valve 31, thus allowing the second air compressor 42 to continue operating. In actual operation, even if the dryer does not malfunction, the amount of compressed air produced by the air compressor and the corresponding drying capacity of the dryer are different. The amount of compressed air in the first air compressor system and the second air compressor system can be adjusted by adjusting the opening of the bypass sixth electric valve 43. This will make the amount of compressed air entering the first dryer 32 and the second dryer 46 more balanced and better match the drying capacity of the dryer, thus making the operation of the equipment and the quality of the compressed air produced more stable.

[0020] Similarly, the compressed air flow of the first air compressor system in the second group is as follows: After being filtered by the third intake filter 55, the air passes through the third cooler 54. The air is cooled and absorbs heat in the first cooler 27 before entering the compressor of the third air compressor 56. The compressed air then passes through the twenty-fourth valve 57 and the eighth electric valve 58 into the third dryer 59 for cooling and dehumidification. After cooling and dehumidification, the compressed air exits the third dryer 59 and enters the third air storage tank 62 through the twenty-fifth valve 60. The air from the top of the third air storage tank 62 then enters the distribution cylinder 84 through the twenty-sixth valve 63, the fifth pipe 64, and the thirty-third valve 80. The condensate collected at the bottom of the third air storage tank 62 after being cooled by the third dryer 59 can be discharged through the third drain valve 61. The compressed air flow of the second set of air compressor systems in the first group is as follows: After being filtered by the fourth intake filter 68, the air passes through the fourth cooler 67. The air is cooled and absorbs heat in the fourth cooler 67 before entering the compressor of the fourth air compressor 69. The compressed air then passes through the twenty-ninth valve 72 and the tenth electric valve 71 into the fourth dryer 73 for cooling and dehumidification. After cooling and dehumidification, the compressed air exits the fourth dryer 73 and enters the fourth air storage tank 76 through the thirtieth valve 74. From there, it passes through the thirty-first valve 77 at the top of the fourth air storage tank 76, pipe 78, and valve 79 into the distribution cylinder 84. The condensate collected at the bottom of the fourth air storage tank 76 after being cooled by the fourth dryer 73 can be discharged through the drain valve 75. A bypass electric valve 70 is installed between the first and second air compressor systems in the second group. When the third dryer 59 malfunctions, the bypass electric valve 70 is opened and the eighth electric valve 58 is closed. The compressed air generated by the third air compressor 56 can then enter the fourth dryer 73 for cooling and dehumidification via the twenty-fourth valve 57, the ninth electric valve 70, and the tenth electric valve 71, thus allowing the third air compressor 56 to continue operating. Similarly, when the fourth dryer 73 malfunctions, the bypass electric valve 70 is opened and the tenth electric valve 71 is closed. The compressed air generated by the fourth air compressor 69 can then enter the third dryer 59 for cooling and dehumidification via the twenty-ninth valve 72, the ninth electric valve 70, and the eighth electric valve 58, thus allowing the fourth air compressor 69 to continue operating. In actual operation, even if the dryer does not malfunction, the amount of compressed air produced by the air compressor and the corresponding drying capacity of the dryer are different. The amount of compressed air in the first and second air compressor systems can be adjusted by adjusting the opening of the bypass ninth electric valve 70. This will make the amount of compressed air entering the third dryer 59 and the fourth dryer 73 more balanced and better match the drying capacity of the dryers, thus making the operation of the equipment and the quality of the compressed air produced more stable.

[0021] In summer, during the operation of the chiller 12, the low-temperature chilled water produced by the chiller 12 enters the water distribution tank 4 through the fourth electric valve 11 and the second valve 6. After flowing out of the water distribution tank 4, the low-temperature chilled water enters the air conditioner 1 and fan coil units through the first valve 5 and the second electric valve 3 to cool the air, thereby providing cool air to the workshop or office area. The low-temperature chilled water cools the air in the air conditioner 1 or fan coil unit, and the chilled water temperature rises. Traditionally, the chilled water is directly returned to the chiller from the air conditioner 1 or fan coil unit for cooling and reuse. Although the temperature of the chilled water flowing out of the air conditioner 1 or fan coil unit in this utility model increases to a certain extent, it is still relatively low compared to the outdoor temperature. At this time, after the chilled water flows out of the air conditioner 1, it first passes through the first electric valve 2, the second pipe 24, and then through the thirteenth valve 26 to enter the first cooler 27 at the air inlet of the first air compressor 29 to cool the air. It then passes through the eighteenth valve 39 to enter the second cooler 40 at the air inlet of the second air compressor 42 to cool the air. Finally, it passes through the twenty-third valve 53 to enter the third cooler 54 at the air inlet of the third air compressor 56 to cool the air. Finally, it passes through the twenty-eighth valve 66 to enter the fourth cooler 67 at the air inlet of the fourth air compressor 69 to cool the air, thus ensuring that the air drawn into each air compressor is cool air. After the chilled water cools the intake air of each air compressor, its own temperature rises again. Then it enters the first pipe 23 through the twelfth valve 25, the seventeenth valve 38, the twenty-second valve 52, and the twenty-seventh valve 65. After that, it flows into the water collection tank 7 through the first pipe 23 and the third valve 8. Then it flows back into the refrigeration unit 12 through the water collection tank 7, the fourth valve 9, and the third electric valve 10. The chilled water is cooled again in the refrigeration unit 12 and then continues to circulate to cool the intake air of the air conditioner 1 and each air compressor.

[0022] Because the compressed air is at a low temperature after passing through each dryer, it contains a certain amount of cooling capacity that can be utilized. Therefore, the compressed air in the distribution cylinder 84 can enter the heat exchanger 19 through the thirty-sixth valve 83, the seventh pipe 85, and the tenth valve 20. After being initially cooled by the cooling water of the refrigerator 12 in the heat exchanger 19, the compressed air that has absorbed heat flows out of the heat exchanger 19 and is then delivered to the air-using equipment 22 through the eleventh valve 21. At the same time, the cooling water of the refrigerator 12 absorbs heat in the refrigerator 12 and enters the heat exchanger 19 through the fifth valve 13 and the ninth valve 18. It is initially cooled by the compressed air. After being cooled in the heat exchanger 19, the cooling water flows out through the eighth valve 17 and into the cooling tower 16. After being cooled again, the cooling water flows out of the cooling tower 16 and enters the refrigerator 12 again through the seventh valve 15 and the sixth valve 14 to carry away the heat of the refrigerator. This cycle continues continuously.

[0023] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
