Embodiment

[0025] see Figure 1 to Figure 4 , the pipeline safety protection device in the illustration is a preferred embodiment of the present invention, specifically including a pneumatic damper 1, a cylinder 2, a fixed mounting seat 3, a sealing strip 4, a moving flange 5, a fireproof soft cloth 6, and a reinforcing flange 7 , Fixed flange 8 and guide rod 9 and other components. The pipeline safety protection device of this embodiment is installed on the air inlet pipeline of the VOCs exhaust gas adsorption device, and is connected to the place or the drainage fan that generates VOCs gas through the pipeline 11. It is collected into a closed container through pipelines for adsorption. The pneumatic air valve 1 is installed at the air inlet of the airtight container 10, and then the pipeline 11 is detachably connected to the air inlet of the pneumatic air valve 1 through the flexible fireproof connecting pipe 6. The flexible fireproof connecting pipe 6 Quick disconnect and connect fr...

Abstract

The invention discloses a safety protection device for a pipeline. The safety protection device for the pipeline is installed on an air inlet pipeline of a VOCs waste gas adsorption device, and is connected to a place generating VOCs gases or a drainage fan through a pipeline; and the safety protection device for the pipeline is capable of detachably butting the pipeline with the VOCs waste gas adsorption device, and an air valve is arranged at an air inlet port of the VOCs waste gas adsorption device. The safety protection device for the pipeline, which is disclosed by the invention, is capable of rapidly butting and disconnecting the pipeline connected with the VOCs adsorption device, without influence on a normal conveying function of the pipeline; and during desorption catalytic combustion of the VOCs adsorption device, the safety protection device for the pipeline effectively disconnects the connected pipeline and closes the air valve to thoroughly cut off connection between the pipeline and a workshop, thus effectively preventing an accident (combustion) of the VOCs adsorption device from diffusing into the pipeline, and preventing the accident from spreading to the workshop.

Description

technical field [0001] The invention relates to a pipeline safety protection device for quick connection and disconnection of pipelines. Background technique [0002] In the place where VOCs waste gas is generated, on the one hand, it is necessary to ensure that the operating environment complies with the "Industrial Enterprise Design Hygienic Standard" (GBZ1-2002), and on the other hand, it is necessary to ensure that the emission complies with the "Comprehensive Emission Standard of Air Pollutants" (GB16297-1996). The process method of VOCs waste gas is adsorption + catalytic combustion. This method is to use adsorption materials to absorb VOCs waste gas in a closed container. After the adsorption is saturated, the VOCs waste gas adsorbed on the surface of the adsorption material is desorbed and converted into carbon dioxide and carbon dioxide after combustion. For water vapor emission, when absorbing VOCs exhaust gas, it is necessary to introduce the exhaust gas into the ...
