Method for mechanically repelling pests inside production workshop line pipes and pipelines

The invention relates to the technical field of mechanical equipment, discloses a method for mechanically repelling pests inside production workshop line pipes and pipelines, and relates to existing production workshop line pipes or/and pipelines. The method is characterized by comprising the following steps that 1) a ventilation connector is installed in any position of various line pipes or/andpipelines of a production workshop; 2) a production pause period of the workshop is selected, the ventilation connector is connected with a gas production port of a nitrogen making machine or an ozonegenerator through a soft gas pipe, the gas flow in the line pipes or/and pipelines is kept smooth, the nitrogen making machine or the ozone generator is started, and high-purity nitrogen or ozone generated by the nitrogen making machine or the ozone generator is introduced into the line pipes or/and pipelines through the installed ventilation connector to repel or prevent the pests. By means of the method, rapid mechanica
