Method and system for preventing and treating pests by using smoke from biomass power plant in sealed space

摘要

A system and method for preventing and treating limited space using smoke from a biomass power plant. The smoke from the biomass power plant is treated to obtain treated smoke with a carbon dioxide volume concentration of 85 vol.%, And the prevention and treatment processes are performed in a sealed space using Mode I, mode, . Mode I: the gas pressure in the confined space reaches 0.110 to 0.140 megapascals (absolute pressure), and after a certain retention time, the volume of carbon dioxide in the confined space reaches 50 to 90 vol% A mode of continuously aerating a space limited by the flue gas and stopping venting of the confined space using the flue gas treated until the confined space returns to a steady state; Mode: When diseases and pests occur during the crop planting process such that the gas pressure in the confined space reaches 0.110 to 0.140 mega pascals (absolute pressure) and the volume concentration of carbon dioxide in the confined space reaches 50 to 90% Continuously aerating the space limited by the flue gas; Controlling the time for each successive introduction of 15 to 16 minutes of treated flue gas; Stopping the introduction of the treated flue gas until the pressure returns to normal and the volumetric concentration of carbon dioxide decreases to less than 5v.%; A mode in which the ventilation of the space limited by the flue gas treated after a certain interval is repeated.
