[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a smoking room in a passenger compartment of a high-speed train, provided as a specific embodiment of the present invention.
[0024] This utility model provides a smoking room in a passenger compartment of a high-speed train. The smoking room 1 is equipped with an air purification device and has an air outlet, which can be located at the top, side, or bottom of the smoking room 1. Since the smoking room 1 is usually placed in the passenger compartment, when the air outlet is located at the bottom of the smoking room 1, a pipe connected to the air outlet should be pre-embedded in the bottom of the passenger compartment to facilitate air discharge. The air purification device includes a duct 2 and a multi-stage filtration unit installed in the duct 2. One end of the duct 2 has an air inlet that communicates with the interior of the smoking room 1. A filter screen can be installed at the air inlet to prevent foreign objects from entering the duct. The other end of the duct 2 has a fan 8, which can discharge the air filtered by the multi-stage filtration unit through the air outlet. The multi-stage filtration unit can ensure that the air flowing out of the smoking room 1 meets the requirements, thereby improving the passenger experience.
[0025] In some embodiments, the multi-stage filtration unit includes a porous filtration module 3 and a water filtration module 4. The flue gas entering the air duct 2 passes through the porous filtration module 3 and the water filtration module 4 in sequence. The porous filtration module 3 can be selected as a filter screen. Through the adsorption and solubility of the water filtration module 4, particulate matter and harmful gases in the flue gas can be effectively absorbed. The water filtration module 4 has the advantage of low cost. The water filtration module 4 needs to be replaced regularly to ensure the filtration effect of the water filtration module 4.
[0026] In some embodiments, the multi-stage filtration unit further includes a non-woven fabric filter module 5 and an activated carbon filter module 6 disposed sequentially downstream of the water filter module 4. The flue gas filtered by the water filter module 4 will be filtered by the non-woven fabric filter module 5 and then by the activated carbon filter module to remove the odor from the flue gas.
[0027] In some embodiments, the multi-stage filtration unit further includes a high-voltage ionization module 7 located downstream of the activated carbon filter module 6. The high-voltage ionization module 7 effectively reduces PM2.5 in the flue gas, thereby improving the flue gas filtration effect. The porous filter module 3, water filter module 4, non-woven fabric filter module 5, activated carbon filter module 6, and high-voltage ionization module 7 are arranged sequentially along the airflow direction within the air duct 2, as shown in the airflow direction... Figure 1 As shown by the arrow in the image.
[0028] In some embodiments, the smoking room 1 is equipped with a sensor 11 for detecting PM2.5 concentration. When the sensor 11 detects that the PM2.5 concentration is higher than a preset value, a multi-stage filtration device can be activated; when the sensor 11 detects that the PM2.5 concentration is lower than the preset value, the multi-stage filtration device can be deactivated to reduce energy consumption. Multiple sensors 11 can be installed in the smoking room 1 at different locations. The average value detected by the multiple sensors 11 can be compared with a preset value, or the highest and lowest values can be removed, and the average value of the remaining values can be compared with the preset value. Therefore, using multiple sensors 11 can improve the accuracy of detection.
[0029] In some embodiments, to improve the level of automation, the multi-stage filtration unit further includes a controller connected to the sensor 11. The controller is configured to respond when the sensor 11 detects PM2.5 ≥ 75 μg / m³. 3 At this time, the multi-stage filtration unit is activated for filtration, such as by starting the fan 8 and the high-voltage ionization module 7.
[0030] In some embodiments, the controller is connected to the high-voltage ionization module 7, and the controller is used when the sensor 11 detects 75 μg / m³. 3 <PM2.5≤200μg / m 3 At that time, the high-voltage ionization module 7 is controlled to operate at the first power; when 200μg / m 3 <PM2.5≤400μg / m 3 At that time, the high-voltage ionization module 7 is controlled to operate at the second power; when 400μg / m 3When PM2.5 levels are below a certain threshold, the high-voltage ionization module 7 operates at its third power level. The first, second, and third power levels of the high-voltage ionization module 7 increase sequentially; that is, the higher the PM2.5 concentration, the greater the operating power of the high-voltage ionization module 7, and the lower the concentration, the lower the operating power, thereby achieving the purpose of energy saving and consumption reduction. It should be noted that in this embodiment, the high-voltage ionization module 7 has three power levels: first, second, and third. More power levels can be added according to actual needs.
[0031] In some embodiments, a filter cabinet 9 is provided inside the smoking room 1, positioned at the rear. A multi-stage filtration unit is housed within the filter cabinet 9. The filter cabinet 9 has an openable door at the front for easy maintenance of the multi-stage filtration unit. Furthermore, the filter cabinet 9 also provides protection for the multi-stage filtration unit. Additionally, the door is equipped with a combination lock or biometric lock to prevent unauthorized opening of the filter cabinet 9, thus enhancing the security of the multi-stage filtration unit within the filter cabinet 9. A cigarette burner 10 can be installed on the upper surface of the filter cabinet 9 for user convenience.
[0032] In some embodiments, the smoking room 1 includes a cuboid frame, a cover panel, and a transparent curtain. The cuboid frame can be welded from metal profiles. The transparent curtain is located at the front of the cuboid frame, allowing users to enter and exit the smoking room 1 by lifting the transparent curtain. The remaining sides and top of the cuboid frame are respectively covered with a cover panel, for example, aluminum cover panels. The transparent curtain allows external users to easily observe the situation inside the smoking room 1. For example, if there are many smokers in the smoking room 1, they can enter later to avoid frequently lifting the transparent curtain and causing unpurified smoke to escape from the smoking room 1. Furthermore, where space permits, two openable doors, designated as the inner door and the outer door, can be installed in front of the smoking room 1. When a smoker needs to enter the smoking room 1, the outer door is opened first. After entering between the inner and outer doors, the outer door is closed, and then the inner door is opened. Since the outer door is closed, smoke leakage is prevented. After entering the smoking room 1, the inner door is closed. When a smoker needs to exit the smoking room 1, the inner door is opened first. After entering between the inner and outer doors, the inner door is closed to prevent smoke leakage from the smoking room 1. Then, the outer door is opened, and the smoker can exit. A smoke extractor can also be installed in the cavity between the inner and outer doors to draw any smoke leaking into the cavity back into the smoking room 1. Additionally, the filter cabinet 9 is preferably a rectangular structure. The dimensions of the smoking room 1 can be 3m × 1.2m × 2.5m, and the dimensions of the filter cabinet 9 are 2.8m × 0.6m × 1m.
[0033] In some embodiments, an air purification device is provided on each side of the smoking room 1, and the two air purification devices share a single fan 8. The air inlets of the air ducts 2 of both air purification devices face the center of the smoking room 1, and the air ducts 2 are preferably located close to the wall inside the smoking room 1. Using two air purification devices can effectively improve the air purification effect, and sharing a single fan 8 can reduce equipment costs. Figure 1 As shown, an air purification device is installed on the left and right sides of the smoking room 1, and a fan 8 is installed in the middle of the filter cabinet 9. The high-voltage ionization module 7 of the air purification devices on both sides is connected to the fan 8. When the fan 8 is running, it can draw in the smoke in the smoking room 1 from both sides at the same time, thus effectively improving the smoke purification efficiency.
