The invention belongs to the technical field of pipeline explosion prevention, and discloses a pipeline spark detecting and extinguishing system and a control method thereof. The pipeline spark detecting and extinguishing system comprises a main pipeline, a first detecting assembly, a first fire extinguishing mechanism, a spark removing mechanism and a control assembly, a normally open valve is arranged at the outlet end of the main pipeline, the first detecting assembly is arranged at the inlet end of the main pipeline, and the first fire extinguishing mechanism comprises a second detecting assembly and a first extinguishing structure; the second detection assembly is located on the downstream of the first extinguishing structure in the conveying direction of materials, the outlet end of the first extinguishing structure communicates with the interior of the main pipeline, the first extinguishing mechanism is located on the downstream of the first detection assembly in the conveying direction of the materials, and the spark removing mechanism comprises an auxiliary pipeline, a first fan, a normally-closed valve and a third detection assembly. The normally-closed valve and the third detection assembly are both arranged on the auxiliary pipeline, the inlet end of the auxiliary pipeline is communicated with the main pipeline and located between the second detection assembly and the normally-open valve, and the outlet end of the auxiliary pipeline is communicated with the first draught fan.
Description
technical field [0001] The invention relates to the technical field of pipeline explosion protection, in particular to a pipeline spark detection and extinguishing system and a control method thereof. Background technique [0002] Dust explosions are extremely destructive, prone to multiple explosions, and can produce toxic gases. Once such an accident occurs, it can easily cause casualties and pose a great safety hazard. According to statistics, more than 30% of dust explosion accidents are caused by dust removal systems, especially in industries such as metal processing and wood product processing. An explosion is triggered, which seriously threatens the life and property safety of enterprises, employees and surrounding residents. [0003] The spark detection and extinguishing system is an important means and way to reduce the occurrence of dust fires and explosion accidents. However, the existing devices or systems are relatively low in intelligence and reliability, and ...
