Description

Technical Field

[0001] This utility model relates to the field of leakage detection technology, and in particular to a methanol leakage alarm device for a pyrolysis reactor. Background Technology

[0002] A pyrolysis reactor is a device used to decompose organic matter into smaller molecules at high temperatures. It has wide applications in many fields such as chemistry, materials, and energy. However, methanol in a pyrolysis reactor is highly toxic and has a significant impact on the human nervous and circulatory systems. To reduce safety hazards and ensure the normal operation of the pyrolysis reactor, leak detection is necessary.

[0003] Currently, existing methanol gas detectors are devices used to detect the concentration of methanol gas in the air. They mainly consist of a controller and a detector, connected by a signal cable. They are widely used in the petrochemical industry, such as oil, gas, chemical, and oil depots, where toxic gases are present, to detect leaks in indoor and outdoor hazardous locations. They are important instruments for ensuring production and personal safety. When toxic gas is present in the tested area, the detector converts the gas signal into a voltage or current signal and transmits it to the alarm instrument. The instrument displays the percentage concentration value of the toxic gas's upper explosive limit. When the concentration of toxic gas exceeds the alarm set value, an audible and visual alarm signal is triggered, allowing on-duty personnel to take timely safety measures to prevent combustion and explosion accidents.

[0004] However, most existing cracking reactors have potential leaks at the pipeline flange. When methanol gas detectors are installed directly around the flange, there is a lack of auxiliary fixing structures, which makes the installation of the detectors time-consuming, labor-intensive, and inefficient. Furthermore, due to the large space they are located in, the detection effect may be poor. Utility Model Content

[0005] To overcome the problem that the methanol gas alarm lacks an auxiliary fixing structure when installed around the flange, resulting in time-consuming and labor-intensive installation, low efficiency, and potential poor detection effect due to its location in a large space.

By setting upper shell and lower shell, it is convenient to form a closed space outside the flange, so that the detection of methanol gas alarm is more timely and accurate.

[0009] Preferably, the outer side of the replacement plate two is slidably sleeved with the limiting groove two, and the lower end of the replacement plate two is provided with the engaging groove two. The lower end of the replacement plate two and the mounting base two are detachably connected by the fixing bolt two.

[0011] Preferably, the installation chamber and the lower shell are integrally formed, and the inner sides of the installation chamber and the lower shell are connected to each other. The methanol gas alarm and the upper end of the installation chamber are detachably connected, and the lower end of the methanol gas alarm extends to the inner side of the installation chamber and is equipped with a detection probe.

[0014] The beneficial effects of this utility model are:
