Model of biogas flame arrester：GZW-Z

Product IntroductionbiogasblockfiredeviceIt is to prevent external flames from entering equipment or pipelines containing flammable and explosive gases, or to prevent flames from spreading between equipment and pipelines. Flame arresters are used to prevent the spread of flames

When passing through the narrow pores of a thermal conductor,The principle of extinguishing due to heat loss is designed and manufactured. The biogas flame arrester is suitable for installation on pipelines and storage tanks that transport combustible biogas gas, to prevent

Stop the reverse propagation of flames in the pipeline under abnormal conditions to avoidThe occurrence of catastrophic accidents. The fire-resistant plate is made of stainless steel material, which is corrosion-resistant and easy to clean. The shell is made of stainless steel

Steel, carbon steel, aluminum alloy, and cast steel are various materials that can meet the needs of different process pipelines. The biogas flame arrester produced by our company has a compact structure, high reliability, and flame retardant core

The product has advantages such as explosion-proof, anti-corrosion, strong fire resistance, and easy cleaning. Suitable for the storage and torch of flammable gas pipelines, such as gasoline, kerosene, light diesel, benzene, toluene, crude oil and other oil products

system,It can also be used as pipeline supplies for acetylene, oxygen, nitrogen, and natural gas.

阻火器工作原理The flame retardant core of the biogas flame arrester is made of stainless steel“N”The double-layer corrugated tape is a fire-resistant core component with a cross shaped bracket inside the core component (or on the table)

Press on the surfaceYThe frame is used to enhance the reliability of the core components and prevent the explosive pressure generated by the medium that ignites the core components from dissipating. Design the height of the triangular hole based on this principle to prevent the passage of flames

By adding sufficient channel length to absorb the heat of the flame, it can be extinguished in the core, avoiding the possibility of gas reigniting at the other end of the core.

Installation and maintenance of biogas flame arresters:

1、 In order to ensure the performance of the flame arrester meets its intended use, it is necessary to carefully read the instructions provided by the manufacturer before installing the flame arrester, and carefully check whether the label is consistent with the requirements of the installed pipeline.

2、 The flow direction mark on the flame arrester must be consistent with the flow direction of the medium.

3、 It should be checked every six months. Check whether the fire-resistant layer has defects such as blockage, deformation, or corrosion.

4、 The blocked fire-resistant layer should be cleaned thoroughly to ensure that each hole is unobstructed, and any deformed or corroded fire-resistant layer should be replaced.

5When cleaning the flame arrester core components, high-pressure steam, non corrosive solvents, or compressed air should be used for blowing, and sharp hardware brushes should not be used.

6、 When reinstalling the flame retardant layer, the gasket should be updated and the sealing surface should be confirmed to be clean and undamaged, without any air leakage
