Abstract
Description
Technical Field
[0001] This application relates to the technical field of sampling devices, and in particular to a multifunctional absorption sampling box. Background Technology
[0002] Gaseous pollutants (such as ammonia, hydrogen fluoride, and hydrogen chloride), especially those generated by specific industrial stationary pollution sources, require manual sampling and laboratory testing and analysis. According to the detection standards for gaseous pollutants such as ammonia, hydrogen fluoride, and hydrogen chloride (HJ 533-2009, HJ 688-2019, HJ 549-2016), these pollutants require sampling of ambient air and exhaust gases using liquid absorption. During sampling, the target pollutant flows through the sampling tube and absorption bottle at a certain flow rate in a sealed environment, thereby achieving sample enrichment.
[0003] When collecting waste gas from industrial stationary pollution sources, the flue gas temperature is significantly higher than the ambient temperature. According to the sampling technology requirements, in order to prevent condensation in the sampling pipeline, the sampling pipeline needs to be insulated / heated to about 120°C before being introduced into the absorption bottle in an ice bath environment. However, the cooling effect of the ice bath environment will affect the absorption efficiency and the penetration rate of the absorption bottle, ultimately affecting the validity and quality control of the test results.
[0004] In addition, since the absorption bottles required for collecting different types of gas samples have different specifications, if the absorption bottles are not properly secured, they are prone to tipping over and overflowing during operations such as connecting tube disassembly and assembly, replenishing ice bath coolant, and sample replacement, resulting in sample loss and contamination.

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this application.
[0042] It should be noted that if the terms "first," "second," etc., appear in the specification, claims, and accompanying drawings of this application, such descriptions are only used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a system, product, or device that comprises a series of units, modules, or components is not necessarily limited to those explicitly listed, but may include other components not explicitly listed or inherent to such systems, products, or devices.
[0043] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.
[0044] In some embodiments, such as Figure 1-2 As shown, this application provides a multifunctional absorption sampling box, specifically including a cover plate 1, a sampling box body 2, a portable handle 3, a box body connector 4, and a temperature control panel 9. The box body is generally quadrilateral and equipped with a portable handle 3 for easy handling and storage. The box body connector 4 can rotate 270°. When open, the cover plate 1 fits snugly against the box body 2. When closed, the cover plate 1 can cover the upper edges of the sampling box body 2, which can play a certain role in heat preservation. The temperature inside the box can be monitored in real time through the temperature control panel.
[0045] like Figure 2 As shown, the internal structure of the multifunctional absorption sampling box of this application includes a fixing device 5, a cooling device 6, an ice box 7, and a power supply module 8. The cooling device 6 is suspended inside the sampling box 2, and the fixing device 5 is mounted on the cooling device 6. The fixing device 5 includes a fixing groove 51 and a fixing spring plate 52. The fixing spring plate 52 is disposed inside the fixing groove 51. The fixing device 5 is used to fix the absorption bottle. The cooling device 6 includes an inlet 61, an outlet 62, a water tank 63, a semiconductor cooling chip 64, heat dissipation fins 65, and an exhaust fan 66. The water tank 63 is connected to the inlet 62 and the outlet 63. The cold end of the semiconductor cooling chip 64 is in direct contact with the water tank 63, and the hot end of the semiconductor cooling chip 64 is connected to the heat dissipation fins 65. The exhaust fan 66 is disposed on the side of the heat dissipation fins 65. The airflow of the exhaust fan 66 passes vertically through the heat dissipation fins 65 and promotes airflow in the bottom and side cavities of the sampling box 2 to dissipate the heat from the heat dissipation fins 65 from the side cavities. The ice box trough 7 is located in the cavities on both sides of the sampling box 2; the ice box trough 7 is wider at the top and narrower at the bottom, and the lower end of the ice box trough 7 is connected to the interior of the water tank 63.
[0046] In some embodiments, in order to fix absorption bottles of different specifications using the fixing device 5, the fixing device 5 consists of two layers of fixing grooves 51 placed in the water tank 63 and fixing spring plates 52. It is compatible with common 10mL-100mL absorption bottles for gaseous pollutants such as ammonia, hydrogen fluoride, and hydrogen chloride. Preferably, the distance between the two fixing grooves is 12cm, the inner diameter of the fixing groove is 5cm, the length of the fixing spring plate can be set to 2cm, and the bending angle of the rotating shaft of the fixing spring plate 52 is 90°. As the deflection angle increases, the fixing force gradually increases. In addition, the surface of the fixing spring plate 52 can be processed into a frosted rough surface or wrapped with a certain anti-slip rubber layer to further improve the stability of the fixation.
[0047] In some embodiments, in order to achieve portability and good cooling effect of the cooling device 6, preferably, the water tank 63 can be made of stainless steel and directly contacted with the cold end of the semiconductor cooling chip 64 by welding copper sheets. In use, the absorption bottle is inserted into the fixing device 5, and the cooling device 6 is powered by DC through the power supply module 8 to cool the water tank 63 containing the absorption bottle. Depending on the ambient temperature and cooling effect, ice packs can be placed in the ice box slots 7 on both sides of the cabinet 2 to assist in cooling. The ice box slots 7 and the module of the cooling device 6 are located on different sides, and the ice box slots 7 will not affect the cooling effect of the cooling device 6. Specifically, water can be injected into the water tank 63 through the water inlet 61 or the fixing groove 51. The cabinet is equipped with water level and temperature sensors, and the information is displayed on the temperature control panel 9. When the water level reaches the height required by the corresponding absorption tube, the cooling device 6 can be started. The cold end of the semiconductor cooling chip 64 begins to cool, and the hot end begins to generate heat. Thermal grease is used to tightly attach the hot end of the cooling chip to the heat sink fins to reduce contact thermal resistance and improve heat transfer efficiency. The cooling fan 66 is fixed to the side of the heat sink fins to ensure that the airflow passes vertically through the heat sink fins, promotes airflow in the bottom and side cavities of the cabinet, and conducts the heat from the heat sink fins 65 and the bottom power supply module 8 from both sides.
[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
