Description

Technical Field

[0001] This application relates to the field of ambient air monitoring technology, and specifically discloses a hydrogen chloride sampling device that is easy to seal. Background Technology

[0002] Hydrogen chloride, with the chemical formula HCl and a molecular weight of 36.461, is a colorless, irritating, corrosive, and asphyxiating gas that strongly fumes in moist air. A hydrogen chloride molecule consists of one chlorine atom and one hydrogen atom. Hydrogen chloride is readily soluble in water and alcohol, and also soluble in ether. Its aqueous solution is called hydrochloric acid, also known as hydrochloric acid.

[0003] During the sampling of hydrogen chloride from ambient air, exhaust gas, and stationary pollution sources, the presence of chlorine (Cl), sulfides, sulfur dioxide, particulate chloride, etc., in the exhaust gas can interfere with the determination of hydrogen chloride. Tap water, airborne dust, and chlorine residue on hands can also cause interference during on-site operations.

[0004] Throughout the hydrogen chloride sampling and analysis process, numerous external interference factors exist. Through experiments covering the entire sampling and analysis process, the accuracy of the sampled and analyzed samples is ensured. By optimizing and improving the entire sampling and analysis process, the potential for hydrogen chloride contamination during sampling and analysis can be reduced or even eliminated, thereby improving the accuracy of the data. This is of great significance for ambient air monitoring.

[0005] Currently, hydrogen chloride is typically sampled by connecting a sampling bottle to a gas tube. A gas pump is used to introduce the collected gas into the sampling bottle, which is then sealed with a cap after collection. However, this method of sampling is prone to interference from external factors during the sealing process, which can affect the determination of hydrogen chloride and result in inaccurate results reflecting the emission and pollution levels of hydrogen chloride. In view of this, this invention provides a hydrogen chloride sampling device that is easy to seal, in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that during the sealing process of traditional sampling bottles, the gas inside the sampling bottle is affected by external factors, resulting in the detection results failing to accurately reflect the emission and pollution level of hydrogen chloride.

[0007] To achieve the above objectives, the basic solution of this utility model provides a hydrogen chloride sampling device that is easy to seal, comprising:

[0008] Bottle body;

[0009] A sealing assembly is provided at the opening of the bottle body. The sealing assembly includes a sealing plate at the opening of the bottle body, a fixing ring at the periphery of the sealing plate, and an adjusting plug rotatably connected to the fixing ring. The sealing plate is provided with a guide hole communicating with the inside of the bottle body, and the adjusting plug is provided with a plurality of connecting holes that can communicate with the guide hole.

[0010] The principle and effect of this basic scheme are as follows:

[0011] This invention controls the sealing and opening of the bottle by rotating the adjusting plug to adjust the fit between the connecting hole and the guide hole. This allows for convenient sealing of the bottle during hydrogen chloride sampling, reducing or even eliminating the possibility of hydrogen chloride contamination during sampling. This ensures the accuracy and reliability of hydrogen chloride analysis results, accurately reflecting the emission status and pollution level of hydrogen chloride.

[0012] Furthermore, the sealing plate is also provided with a sealing ring located inside the fixing ring, and the bottom of the adjusting plug is provided with an inner groove that matches the sealing ring. This improves the sealing performance between the connecting hole and the guide hole.

[0013] Furthermore, the top of the sealing ring is provided with a stepped platform, and a sealing ring is provided between the stepped platform and the inner groove. This further improves the sealing performance between the connecting hole and the guide hole.

[0014] Furthermore, both the outer wall of the adjusting plug and the outer wall of the sealing ring are provided with a plurality of elastic blocks. When the adjusting plug is assembled with the fixing ring and the sealing ring, the elastic blocks are in a compressed state. This makes the fit between the adjusting plug and the sealing ring and the fixing ring tighter, and avoids misalignment between the connecting hole and the guide hole due to positional deviation of the adjusting plug.

[0015] Furthermore, the sidewall of the fixed ring is provided with a groove, and part of the elastic block is located within the groove. This facilitates the rotation of the adjusting plug from the outside, and the elastic block effectively increases the friction when rotating the adjusting plug.

[0016] Furthermore, the fixing ring includes an upper ring body and a lower ring body that are detachably connected to each other. The lower ring body is provided with several slots, and the upper ring body is provided with locking blocks that are adapted to each slot. The top of the upper ring body is provided with a retaining ring that is adapted to the periphery of the adjusting plug. Through the cooperation of the upper and lower ring bodies, the adjusting plug is limited, thereby facilitating the sealing of the bottle.

[0017] Furthermore, the diameter of the connecting holes increases sequentially, and the top of the adjusting plug is provided with connecting pipes that communicate with each connecting hole, with sealing caps provided at each connecting pipe. This is to accommodate sampling pipes of different diameters and facilitate interconnection with sampling pipes. Attached Figure Description

[0021] Figure 3 A schematic diagram of the sealing component in a hydrogen chloride sampling device that is easy to seal, according to an embodiment of this application, is shown. Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] The reference numerals in the accompanying drawings of the instruction manual include: bottle body 1, fixing ring 2, upper ring body 201, lower ring body 202, adjusting plug 3, sealing cap 4, connecting pipe 5, sealing plate 6, sealing ring 7, stepped platform 8, sealing ring 9, inner groove elastic block 10, end face elastic block 11, locking block 12, and locking groove 13.

[0024] A hydrogen chloride sampling device that is easy to seal, for example... Figure 1 As shown, it includes a bottle body 1 and a sealing assembly disposed at the opening of the bottle body 1, wherein, as Figure 2 and Figure 3 As shown, the sealing assembly includes a sealing plate 6 at the opening of the bottle body 1, a fixing ring 2 at the periphery of the sealing plate 6, and an adjusting plug 3 rotatably connected to the fixing ring 2. The fixing ring 2 includes an upper ring body 201 and a lower ring body 202 that are detachably connected to each other. The lower ring body 202 is provided with a plurality of slots 13, and the upper ring body 201 is provided with a locking block 12 that is adapted to each slot 13. The top of the upper ring body 201 is provided with a retaining ring that is adapted to the periphery of the adjusting plug 3, thereby restricting the top of the adjusting plug 3.

[0025] The sealing plate 6 is fixed to the bottom of the lower ring 202. The sealing plate 6 has a guide hole that communicates with the inside of the bottle 1. Correspondingly, the adjusting plug 3 has several connecting holes that communicate with the guide hole, and the diameter of the connecting holes increases sequentially. The top of the adjusting plug 3 has a connecting tube 5 that communicates with each connecting hole, and a sealing cap 4 is provided at each connecting tube 5. The connecting tube 5 and the sealing cap 4 are connected by threads, which not only facilitates disassembly but also makes it easy for the connecting tube 5 to be matched with the sampling pipe for sampling. Furthermore, the connecting hole and the connecting tube 5 have different diameters, which facilitates matching with sampling pipes of different diameters.

[0026] The side wall of the fixed ring 2 is provided with a groove, and the outer wall of the adjusting plug 3 is provided with multiple end face elastic blocks 11. Some end face elastic blocks 11 are located in the groove. The end face elastic blocks 11 effectively increase the friction when rotating the adjusting plug 3, so that the adjusting plug 3 can be rotated from the outside. At the same time, the squeezing force on the end face elastic blocks 11 will also prevent the adjusting plug 3 from shaking.

[0027] To improve the sealing performance between the connecting hole and the guide hole, a sealing ring 7 located inside the fixing ring 2 is provided on the sealing plate 6. The bottom of the adjusting plug 3 is provided with an inner groove that matches the sealing ring 7. The top of the sealing ring 7 is provided with a stepped platform 8. A sealing ring 9 is provided between the stepped platform 8 and the inner groove. The outer wall of the sealing ring 7 is provided with multiple inner groove elastic blocks 10 to further prevent the adjusting plug 3 from deviating in position, which could lead to misfitting between the connecting hole and the guide hole.

[0028] In this embodiment, when the adjusting plug 3 is assembled with the fixing ring 2 and the sealing ring 7, both the end face elastic block 11 and the inner groove elastic block 10 are in a compressed state, making the fit between the adjusting plug 3 and the sealing plate 6 relatively tight. During sampling, the corresponding sampling pipe is first connected to the connecting pipe 5, and then the adjusting plug 3 is rotated to make the corresponding connecting hole and the guide hole connected to sample hydrogen chloride. After sampling, the adjusting plug 3 is rotated to make the connecting hole and the guide hole isolated from each other. The sampling pipe is then removed, and the sealing cap 4 is covered to the corresponding connecting pipe 5. This embodiment can reduce or even eliminate the situation where hydrogen chloride is easily contaminated during the sampling process, realize the accuracy and reliability of the hydrogen chloride analysis results, and thus accurately reflect the emission status and pollution level of hydrogen chloride.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
