Ferrous metallurgy environment-friendly waste gas treatment device

Abstract

The invention discloses a ferrous metallurgy environment-friendly waste gas treatment device and relates to the technical field of environment-friendly waste gas treatment. The ferrous metallurgy environment-friendly waste gas treatment device comprises a tank, the inside of the tank is provided with a rotating shaft rotatingly connected to the upper wall of the tank, and the surface of the rotating shaft is fixedly connected with first stirring blades; the upper side of the inner wall of the tank is fixedly connected with a mounting case, inside which a driving gear and a plurality of drivengears engaged with the driving gear are arranged; waste gas at the top of the inside of the tank enters a gas tank via a communicating pipe and is sprayed out via an aerator nozzle; sprayed waste gasis in contact with absorbing solution again to achieve cyclic absorbing effects and to be thoroughly absorbed; the first stirring blades and second stirring blades rotate to fully mix the waste gas and the absorbing solution to enhance absorbing effects of the absorbing solution on the waste gas; the axis of an aeration hole is tangent to the wall of an aeration pipe so that the aeration pipe canachieve aeration in a rotating state to enlarge the aeration area.

Description

technical field [0001] The invention relates to the technical field of waste gas environmental protection treatment, in particular to an environmental protection treatment equipment for iron and steel metallurgy waste gas. Background technique [0002] Metallurgy is the process and technology of extracting metals or metal compounds from minerals, and using various processing methods to make metals into metal materials with certain properties. Metallurgy has a long history of development, from the Stone Age to the subsequent Bronze Age, to the large-scale development of modern iron and steel smelting. The history of human development incorporates the history of metallurgy. The impurities (unintentional elements) in the metal solution are eliminated by melting (heating above the melting point) for slagging and slag removal. At the same time, some chemical components can be relatively pure alloy components through slag removal, decarburization, and oxygen removal. the process...
