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...

Embodiment 1

[0029] Embodiment 1 of the present application provides a method such as Figure 1 to Figure 2 The new type of flue gas distributor device with adjustable air duct flow section as shown:

[0030] The device is mainly composed of an inner smoke distributor body 12, an inner air duct cone ring 9, an inner air duct deflector 10, an inner air duct adjustable fan blade 11, an outer air duct cone ring 6, and an outer air duct deflector 7. The external air duct is composed of adjustable fan blades 8, traction wire ropes 4, and motor actuators 5.

[0031] Adjustable fan blades are arranged at the outlets of the tapered ring 9 of the inner air duct and the tapered ring 6 of the outer air duct. ) connection, fan blades (outer air channel adjustable fan blade 8, inner air channel adjustable fan blade 11) are evenly arranged around the central axis of the tapered ring, and the fan blades are staggered and covered, and there is no gap between the blades.

Embodiment 2

[0035] On the basis of the first embodiment, the second embodiment of the present application provides the working method of the novel flue gas distributor device with adjustable air duct flow section in the first embodiment:

[0036] The adjustable blade control strategy is:

[0037] When the amount of waste water decreases during operation, the corresponding amount of flue gas decreases, and the flow velocity of the inner and outer channels of the flue gas distributor (inner air duct cone ring, outer air duct cone ring) becomes smaller. The thermal efficiency is weakened, and the suppression effect of the smoke screen on the spray becomes worse. The angle of the inner and outer air duct blades (inner air duct adjustable fan blades, outer air duct adjustable fan blades) can be adjusted to increase the smoke flow rate and reduce the smoke screen. range, suppress the spray radius, prevent the droplets from sticking to the wall, and at the same time achieve the effect of strengt...
