Air purifying and wet flue gas dehumidifying device

Abstract

The invention discloses an air purifying and wet flue gas dehumidifying device. Wet flue gas enters a spraying mixing unit, is sprayed by a nozzle to be cooled and is sufficiently mixed with sprayed water mist; the mixed wet flue gas enters a high speed peeling unit; due to small centrifugal force, pure air is blocked by a high speed rotating peeling internal cabin and is directly exhausted by anair exhaust passage; partial air and fog drops penetrate through the peeling internal cabin to be thrown to the internal wall of a peeling external cabin so as to form water flow to flow down; partialfine fog drops and the air form an air flow with higher moisture content to enter a condensing and dehumidifying unit; water in the air is separated out to form a water film and a water flow; the wetflue gas which still contains partial fine liquid drops is finally led to an inertial separation unit to be separated; and the treated pure air is exhausted via an air exhaust passage to finish the full process of wet flue gas dehumidifying and air purification. The wind drag in the whole purification and dehumidifying process is lower, requirements on high speed flowing and high throughput treatment of the wet flue gas are satisfied, and the wet flue gas is dehumidified while the air is purified.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification and wet flue gas dehumidification device. Background technique [0002] In recent years, the problem of air pollution has become increasingly serious. There are many types of air purification technologies, such as filtration technology, washing tower, water film fresh air technology, and inertial separation dust removal technology represented by cyclone dust removal. Among them, the inertial separation technology of cyclone dust removal uses the high-speed motion mechanism of the fluid to complete the air purification operation, while other purification technologies either actively or passively realize the air purification operation on the condition of reducing the flow rate. Filtration technology relies on the interception, inertia, diffusion, gravity, static electricity and other effects of filter media to intercept and adsorb suspended particles, a...
