Novel flue gas distributor device with adjustable air flue flow section

Abstract

The invention relates to a novel flue gas distributor device with an adjustable air flue flow section. The novel flue gas distributor device comprises a flue gas distributor, a traction steel wire rope and a motor actuating mechanism, wherein an inlet of the flue gas distributor is connected with a volute isobaric channel; the flue gas distributor is positioned at the top of a drying tower; an inner air duct conical ring is arranged on the surface of a smoke distributor body of the smoke distributor, an inner air duct guide plate is arranged on the inner air duct conical ring, and an inner air duct adjustable fan blade is connected with the inner air duct conical ring bottom of the inner air duct conical ring through a hinge. Beneficial effects are that: the novel flue gas distributor device with the adjustable inner and outer air ducts is provided; the problems that flue gas flow distribution and velocity vectors of the inner and outer air ducts of an existing flue gas distributor cannot be adjusted, flue gas rotational flow and liquid drops are not fully mixed, the drying efficiency is low, fog drops adhere to the tower wall and the like are effectively solved; the structure of the distributor is further innovated, and an inner and outer air duct adjustable executing mechanism is designed.

Description

technical field [0001] The invention belongs to the technical field of waste water zero discharge and the field of rotary spray drying equipment, and in particular relates to a novel flue gas distributor device with adjustable flow section of an air duct. Background technique [0002] As the core device of the spray drying tower, the flue gas distributor is used to evenly send hot flue gas into the drying tower, so that it can fully contact with the atomized wastewater, perform heat and mass transfer, and fully dry the atomized mist droplets. , The salts in the wastewater form powdery substances. At present, the spray drying tower used for zero discharge of waste water, the internal and external air ducts of the flue gas distributor are equal-diameter channels, the flow section is fixed, and the wind speed vector of the internal and external air ducts is fixed. In practical engineering applications, when encountering waste water If the volume changes or the atomization perf...

AI Technical Summary

Problems solved by technology

At present, the spray drying tower used for zero discharge of waste water, the internal and external air ducts of the flue gas distributor are equal-diameter channels, the flow section is fixed, and the wind speed vector of the internal and external air ducts is fixed. In practical engineering applications, when encountering waste water If the volume changes or the atomization performance of the rotating atomizing disc changes, the size and direction of the flue gas at the outlet of the inner and outer air ducts of the distributor cannot be adjusted.

Insufficient gas-liquid heat exchange makes it difficult to control the spray angle and droplet trajectory of rotary atomization in actual engineering operation, which do not match the design value, resulting in uneven mixing of flue gas and atomized droplets, poor adaptability, and failure to spray The droplets are fully dried, and there will be fog droplets sticking to the wall
