Gas analyzing device for limited space

Abstract

The invention discloses a gas analyzing device for limited space. The gas analyzing device comprises a gas detection CPU. The gas detection CPU is respectively connected with a power supply unit, a digital display part, a sound-light alarm module, a wireless module, a gas sensor and a communication unit; the gas sensor is connected with a gas pump, the gas pump is connected with a pipe, and the pipe is connected with the target environment; the sound-light alarm module comprises a sound-light CPU, a sound alarm module, a light alarm module, an analog signal receiving module and a wireless module; the sound-light CPU is respectively connected with the gas detection CPU, the sound alarm module, the light alarm module, the wireless module and the analog signal receiving module. According to the gas analyzing device, the wireless communication mode is adopted, gas detection and alarm indication are combined, an effective emergency damage treatment mode is constructed, it is avoided that gas detection is not timely, and the alarm degree is insufficient, the pumping detection mode is suitable for most of the limited space, continuous detection is carried out in real time, and the personnel safety and the property safety are furthest guaranteed.

Description

technical field [0001] The invention relates to a gas analysis device for confined spaces. Background technique [0002] Confined spaces exist in petroleum, chemical, pharmaceutical, smelting and other fields. The defined confined spaces are all kinds of towers, kettles, tanks, tanks, furnaces, drums, pipes, containers and basements, manholes, pits, sewers or other closed and semi-closed places of chemical production units. Most of these confined spaces have flammable, toxic and other dangerous gases, especially in the daily inspection and maintenance process of confined spaces, there are great safety hazards. At present, there is no gas detection specifically for confined spaces in the industry. Products, the current confined space monitoring mostly uses conventional hand-held gas detection products for detection, and this detection method is a method of contact first and then detection, which requires people to hold a hand-held gas detection instrument for monitoring, and...

Problems solved by technology

Most of these confined spaces have flammable, toxic and other dangerous gases, especially in the daily inspection and maintenance process of confined spaces, there are great safety hazards. At present, there is no gas detection specifically for confined spaces in the industry. Products, the current confined space monitoring mostly uses conventional hand-held gas detection products for detection, and this detection method is a method of contact first and then detection, which requires people to hold a hand-held gas detection instrument for monitoring, and in restricted spaces The general environment of space operations is relatively narrow and dark, and it is generally a closed or semi-closed place. When the gas is detected, people have already penetrated into the hazardous gas, which has a very high personal safety hazard.

Although the person in charge of the inspection is equipped with a gas mask, and according to the current requirements of the "Safety Regulations for Confined Space Operations of Chemical Production Units", it is a periodic inspection, that is, inspections are carried out at intervals, and workers will start operations after confirming safety , and most workers are not equipped with safety equipment such as gas masks, and the confined space environment is complicated, and dangerous gases are often triggered during inadvertent cleaning operations such as decontamination, causing serious personnel and property disasters
