Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically a chemical safety and environmental protection gas sampling device. Background Technology

[0002] Chemical production processes involve the generation and emission of large quantities of flammable, explosive, toxic, and corrosive gases (such as hydrogen, hydrogen sulfide, chlorine, and benzene vapor). These gases are significantly hazardous and complex. On the one hand, leaks into the environment can cause explosions, fires, and poisoning. On the other hand, direct emissions of uncontrolled waste gases can cause air pollution, violating regulations such as the "Air Pollution Prevention and Control Law" and the "Comprehensive Treatment Plan for Volatile Organic Compounds in Key Industries." Therefore, accurate and safe collection of chemical gas samples is a core prerequisite for optimizing production processes, providing early warning of safety risks, and ensuring environmentally compliant emissions.

[0003] A search revealed that patent authorization announcement number CN 221426120 U discloses a chemical safety and environmental protection gas sampling device, which describes "including a stainless steel gas collecting bottle, with an inlet pipe fixedly connected to the other side of the stainless steel gas collecting bottle, an inlet valve fixedly connected to one side of the inlet pipe, and a leak warning structure respectively provided at the ports of the outlet valve and the inlet valve." However, the existing leak detection structure requires manual observation of the rubber diaphragm bulging, which poses a risk of response lag (such as when no one is on duty at night or when personnel forget to check). In addition, although the existing raised dot design of the label pasting area reduces adhesive residue, it cannot completely eliminate the problem of adhesive residue, and manual cleaning is still required, which is time-consuming and laborious.

An inlet valve 6 and an outlet valve 7 are respectively installed on the inlet pipe 4 and the outlet pipe 5. An inlet port 8 is provided at the front end of the inlet pipe 4, and an outlet port 9 is provided at the bottom end of the outlet pipe 5. A gradient interface 10 / leakage alarm mechanism 11 is installed on the inlet port 8 and the outlet port 9. The leakage alarm mechanism 11 includes a sealing cap 16, a miniature pressure sensor 17, and an audible and visual alarm module 19. The sealing cap 16 is threaded onto the inlet port 8 / outlet port. On the 9th, a miniature pressure sensor 17 is installed inside the sealing cover 16, directly opposite the air intake port 8 / exhaust port 9. The miniature pressure sensor 17 is model MS5837-30BA. An audible and visual alarm module 19 is installed on the end face of the sealing cover 16. The audible and visual alarm module 19 is model PKM13EPYH4000-B0. The miniature pressure sensor 17 and the audible and visual alarm module 19 are electrically connected. A button battery 18 is also provided inside the sealing cover 16. A removable battery cover is provided on the sealing cover 16 corresponding to the position of the button battery 18. The button battery 18 is used to power the miniature pressure sensor 17 and the audible and visual alarm module 19.

[0020] Please see Figure 1 The stainless steel gas collecting bottle 1 is equipped with support legs 3 at the bottom. The two ends of the support legs 3 are hinged to the support leg limit seats 2 installed on both sides of the stainless steel gas collecting bottle 1. The support legs 3 can be set so that the stainless steel gas collecting bottle 1 can be placed off the ground to prevent the stainless steel gas collecting bottle 1 from being damaged by friction with the ground. At the same time, the support legs 3 can also be used as handles when they are folded inward, making it easy to carry. A pressure gauge 20 is installed on the exhaust pipe 5. The pressure gauge 20 is used to detect the gas pressure in the stainless steel gas collecting bottle 1 to prevent the gas pressure from being too high and causing danger.

[0021] Please see Figure 1 and Figure 3 A magnetic frame 12 is provided on one side of the stainless steel gas collecting cylinder 1. A label card 13 is magnetically fixed inside the magnetic frame 12. An iron piece 15 is embedded on the back of the label card 13 and magnetically engages with the magnetic frame 12. Notches 14 are provided at the top and bottom of the magnetic frame 12. The notches 14 allow personnel to easily insert their fingers into the magnetic frame 12 to pull out the label card 13.

[0022] The working principle of this utility model is as follows:

[0023] During gas sampling, the gradient interface 10 is first installed on the inlet port 8 of the inlet pipe 4, and then the gradient interface 10 is inserted into the corresponding sampling port for sampling. The sample gas is then stored in the stainless steel gas collecting bottle 1 after the inlet valve 6 is opened. During testing, the gradient interface 10 is first installed on the exhaust port 9, and then the gradient interface 10 is inserted into the corresponding detection port. The exhaust valve 7 is then opened to discharge the gas into the testing equipment, and the gas is exported for component analysis. During storage and transportation, the leakage alarm mechanism 11 is installed on the inlet port 8 and the exhaust port 9 by screwing. When a gas leak occurs at the inlet port 8 / exhaust port 9, the miniature pressure sensor 17 in the leakage alarm mechanism 11 will first sense the pressure, thereby triggering the audible and visual alarm module 19 to alarm, thus achieving the purpose of actively alerting the surrounding personnel.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
