PLANT TO CLEAN HARMFUL EMISSIONS TO ATMOSPHERE

摘要

FIELD: process engineering.SUBSTANCE: proposed plant is mounted at the pipe and comprises cleaning chamber, gas splitter set to change its elevation above said pipe and secured at thrust ring resting on said pipe and welded to cleaning chamber inner wall, and sprinkler to clean gases by sprayed fluid composed of atomisers, water feed system and water discharge pipe. Said plant incorporates extra gas swirling guides, ejector and ozone feed system. Said gas swirling guides are attached to splitter thrust ring and arranged at an angle to plant vertical axis. Ejector inlet is communicated with ozone and water feed systems while its outlet is connected with sprinkler for gas cleaning by sprayed fluid. Note here that sprinkler atomizers cab spray fluid to drop diameter defined by the formulawhere d is drop diameter; D is pipe ID; h is distance from thrust ring to gas flow splitter; V is volumetric flow rate of gaseous combustion product a second; a is angle of gas swirlers arrangement; c is empiric factor calculated by the formulawhere ?, ?are specific weight of gaseous combustion products and fluid drop; Kis coefficient of mutual diffusion of fluid vapor into gaseous combustion products; u is the fluid flow rate relative to combustion products; vis coefficient of kinematic viscosity of gaseous combustion products; B is diffusion head between fluid drop and gaseous combustion products.EFFECT: higher efficiency of cleaning.4 dwg
