Description

Technical Field

[0001] This utility model relates to the field of tobacco production line transformation technology, specifically, to an air conditioning unit for a tobacco production line with a vortex jet purification module. Background Technology

[0002] Tobacco production lines are typically equipped with air conditioning systems. Although each process stage of the tobacco production line is equipped with corresponding waste gas treatment equipment to treat the emitted waste gas in real time, the air cleanliness in the workshop is still not good due to factors such as waste gas overflow, personnel activities, and equipment operation. Therefore, the air conditioning system is mainly used to purify the workshop environment of the tobacco production line.

[0003] Traditional air conditioning units typically include functional modules such as filters, surface coolers, micro-mist humidification modules, heat exchangers, and fans. On the one hand, they filter impurities in the air, and on the other hand, they control the temperature and humidity of the air to create a relatively constant temperature and humidity environment in the workshop.

[0004] However, in actual operation, due to the presence of oily and volatile substances that may appear in the tobacco production line, the filter cartridges are consumed quickly and the ability to remove odors is insufficient. To solve this problem, the air conditioning units need to be modified so that they can reduce costs while meeting the basic requirements of air conditioning units for air filtration and odor removal.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an air conditioning unit for tobacco production lines with a vortex jet purification module that offers advantages such as reduced consumable costs, better dust and odor removal, and improved temperature and humidity control.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an air conditioning unit for a tobacco production line with a vortex jet purification module, comprising a housing and a mixing section, at least one vortex jet purification module, a surface cooler, a heat exchanger and a fan arranged sequentially in the housing along the airflow direction; The front end of the enclosure is provided with a return air vent and the rear end with an air supply vent. Inside the enclosure, there are separate spaces that are sequentially connected for the mixing section, the vortex jet purification module, the surface cooler, the heat exchanger, and the fan. The mixing section is located at the front end of the housing, and the mixing section is equipped with a fresh air intake. The outlet of the mixing section is connected to the inlet of the vortex jet purification module. The vortex jet purification module includes a shell and a vortex jet assembly disposed inside the shell. The bottom of the shell is provided with an inlet and the top is provided with several outlets along the circumferential direction. The surface cooler, heat exchanger, and fan are sequentially arranged behind the vortex jet purification module.

[0008] Based on the above, the inlet of the vortex jet purification module is located on one side of the lower part of the outer shell, and the upper part of the outer shell gradually narrows and is provided with a ring of rectangular openings as the outlet.

[0009] Based on the above, the swirling jet assembly includes a motor, a drive spindle assembly, a first centrifugal fan blade, and a second centrifugal fan blade. The motor drives the first centrifugal fan blade and the second centrifugal fan blade to rotate through the drive spindle assembly, and the second centrifugal fan blade is located above the first centrifugal fan blade.

[0010] Based on the above, an annular baffle is provided above both the first centrifugal fan blade and the second centrifugal fan blade. The diameter of the annular baffle is equal to that of the first centrifugal fan blade and the second centrifugal fan blade. The two annular baffles are respectively positioned close to the first centrifugal fan blade and the second centrifugal fan blade to prevent the rising airflow from overflowing.

[0011] Based on the above, the inlet and outlet of the independent space where the vortex jet purification module, surface cooler, heat exchanger and fan are located decrease in height from the front end to the rear end of the housing.

[0012] Based on the above, the number of the vortex jet purification modules is an even number, arranged symmetrically in two rows.

[0013] Based on the above, the outlet of the mixing section outputs several channels, each channel being connected to the inlet of a vortex jet purification module.

[0014] Based on the above, the mixing section is located at the top of the vortex jet purification module.

[0015] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model removes the traditional filter structure from the original structure of the air conditioning unit and replaces it with the vortex jet purification module of this application. On the one hand, the vortex jet purification module uses water atomization and centrifugal force to adsorb and remove tiny particles in the air conditioner. It mainly consumes water, which is easier to process than the filter and does not affect the normal operation of the process, thus reducing the replacement process. On the other hand, since water atomization itself brings humidity to the air, it reduces the working pressure of the surface cooler and heat exchanger in the subsequent air processing.

[0016] Furthermore, the water mist adsorption method in the vortex jet purification module can also remove some of the air odors, and can even be loaded with deodorizing agents, fragrances and other media, making it more versatile than traditional filter cartridges. Attached Figure Description

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0022] like Figures 1-3 As shown, an air conditioning unit for a tobacco production line with a vortex jet purification module includes a housing 1 and a mixing section 2, at least one vortex jet purification module 3, a surface cooler 4, a heat exchanger 5, and a fan 6 arranged sequentially in the housing along the airflow direction.

[0023] The front end of the housing 1 is provided with a return air inlet 11 and the rear end is provided with an air supply outlet 12. The housing 1 has corresponding independent spaces that are sequentially connected to the mixing section 2, the vortex jet purification module 3, the surface cooler 4, the heat exchanger 5 and the fan 6.

[0024] Specifically, the mixing section 2 is located at the front end of the housing 1. The mixing section 2 is provided with a fresh air supply port 21. The outlet of the mixing section 2 is connected to the inlet of the vortex jet purification module. In this embodiment, the mixing section 2 is located above the vortex jet purification module 3. The side bend serves as the return air port 11, and the top opening serves as the fresh air supply port 21. After the two are fully mixed in the mixing section 2, they are connected to each vortex jet purification module 3 through several channels.

[0025] The vortex jet purification module 3 includes a housing 31 and a vortex jet assembly disposed within the housing 31. The core components of the vortex jet assembly are no different from those of the conventional type, both using a motor 32 to drive centrifugal fan blades. In this embodiment, there are two centrifugal fan blades, including a first centrifugal fan blade 33 and a second centrifugal fan blade 34. In terms of the opening design, the bottom of the housing 31 is provided with an inlet 35, and the top is provided with several rectangular holes along the circumferential direction as an outlet 36. The housing at the outlet gradually narrows to form a frustum shape. The advantage of this design is that the outlets of traditional vortex jet purification modules 3 are all single-channel openings. In this application, the outlet is designed as a ring of rectangular holes, and the rising airflow below is in a vortex state. If it is discharged from a single outlet, it will inevitably cause a large amount of turbulence in the outlet area, requiring subsequent turbulence treatment. In order to optimize the air volume, this solution designs the opening as multiple rectangular holes distributed in a ring. The vortex air can be smoothly discharged from each rectangular hole, achieving airflow guidance and suppression in a relatively larger independent space of the housing, which is more suitable for large-volume airflow.

[0026] Furthermore, in this embodiment, in order to ensure that the air volume processed by the air conditioning unit is sufficient, the number of vortex jet purification modules 3 is set to 6, arranged in two rows. In other embodiments, they can also be stacked according to the specific processing volume, which has good scalability.

[0027] In each vortex jet purification module 3, the motor 32 drives the first centrifugal fan blade 33 and the second centrifugal fan blade 34 to rotate through the drive spindle assembly. The second centrifugal fan blade 34 is located above the first centrifugal fan blade 33. Since the air usually contains fewer impurities than the production process, the stroke can be designed to be shorter. Within the shorter stroke, the air conduction efficiency needs to be considered.

[0028] In this embodiment, an annular baffle 37 is provided above both the first centrifugal fan blade 33 and the second centrifugal fan blade 34. The diameter of the annular baffle 37 is equal to that of the first centrifugal fan blade 33 and the second centrifugal fan blade 34. The two annular baffles 37 are respectively positioned close to the first centrifugal fan blade 33 and the second centrifugal fan blade 34 to prevent the rising airflow from overflowing and to constrain it into a columnar spiral airflow so that it can continue to rise, preventing the airflow from escaping to areas outside the centrifugal fan blades and causing dead zones.

[0029] Of course, several atomizing nozzles will be distributed in appropriate locations inside the housing, such as the area near the inlet 35 of the outer casing 31, especially on the upstream side of the first centrifugal fan blade 33, to provide water mist to the incoming airflow. The water mist is used to adsorb particulate matter and increase its weight so that it can be separated under the action of centrifugal force and gravity.

[0030] The surface cooler 4, heat exchanger 5, and fan 6 are sequentially arranged behind the vortex jet purification module 3. Since the surface cooler 4, heat exchanger 5, and fan 6 are all original configurations of the original air conditioning unit, no further explanation is given, only a functional description. The surface cooler 4 is used to humidify the air. In this embodiment, due to the function of the vortex jet purification module 3, water mist directly intervenes, which will enhance the humidity of the air, thus reducing the working pressure of the surface cooler 4. The heat exchanger 5 is used to heat the air, with the aim of keeping the workshop environment in a relatively constant state.

[0031] Due to the increased humidity of the airflow, the inlet and outlet of the independent space where the vortex jet purification module 3, surface cooler 4, heat exchanger 5 and fan 6 are located decrease in height from the front end to the rear end of the box, which is consistent with the gas settling trend, making it more conducive to gas flow and reducing dead volume.

[0032] Working principle explanation: Air in the workshop is drawn in from various air conditioning return vents and finally collected at the air conditioning unit for unified treatment. First, the air enters the mixing section, where it mixes with some of the incoming clean air to replenish fresh air. After thorough mixing, it enters each vortex jet purification module 3. Water mist nozzles provide water mist, and two centrifugal fan blades provide centrifugal force to quickly separate the water mist and dust mixture from the air. Some odorous gases are also absorbed at the same time. The treated air becomes clean and has some humidity replenishment. Then it enters the subsequent surface cooler for humidification and the heat exchanger for heating. Finally, driven by the fan, it is discharged from the air outlet back into the workshop, forming the air conditioning circulation path.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
