Problems solved by technology

Although the foam dust collector has the advantages of simple structure and low cost, the foam layer is unstable and has certain requirements on the wind speed. If the wind speed does not meet the requirements, it will be difficult to build a foam layer and reduce the purification efficiency. Large, otherwise serious water phenomenon will occur
[0003] In addition, due to the different structures of the wet dust collectors, the effects of treating different dust particle sizes are different.

Embodiment 1

[0019] Embodiment 1 has foam purifier 1, and foam purifier 1 is fixed by support frame 1-9. The inlet and outlet ports 1-1 and 1-8 of the foam purifier 1 are respectively arranged on the upper and lower parts of the cylinder 1, the dust outlet 1-10 is arranged at the bottom of the cylinder, and the inside of the cylinder 1 of the foam purifier At the smoke inlet 1-1, that is, the upper part is provided with a sprayer 2, and the nozzle direction of the sprayer 2 is downward. The distance between 1-6 depends on the exhaust gas discharge and dust concentration, and can reach 2 to 3 meters. The space between the two screens 1-2 and 1-6 is a foam room. In this embodiment, the upper and lower An intermediate screen 1-4 is arranged between the lower screens 1-2 and 1-6, and the upper, middle and lower screens divide the interior of the purification cylinder 1 into 4 chambers, and the middle two chambers 1-3 and 1-5 are In the foam room, the upper mesh plate 1-2 is for foaming, so th...

Embodiment 2

[0023]Embodiment 2 has spray centrifugal scrubber II, foam cleaner I and cooler III, and foam cleaner I is the same as embodiment 1. The scrubber is fixed by a support frame, and the inlet and outlet ports 21-3 and 21-1 of the scrubber are respectively arranged on the lower and upper parts of the cylinder body 21. 21-5 is arranged at the bottom of the cylinder 21, the slag outlet 21-5 is connected to the slag collecting box 24, and the dust removal cylinder 21 is provided with a sprayer 22 and a rotating shaft 23-2, the nozzle of the sprayer 22 is upward, and the rotating shaft 23-2 is connected The main shaft of motor 23-1 on cylinder body 21 top is connected, and rotating shaft 23-2 end is connected with bearing 23-4, and bearing 23-4 is installed in the bearing support 21-4 that is connected with dedusting cylinder 21-1. The rotating shaft 23-2 is connected with the blades 23-3 that generate upward wind force, the washing water tank 26 is arranged on the side of the washing...

Abstract

The invention is a kind of dust catching and smoke clarifying device which uses clarifier to form foam layer. It has foam clarifier, there's sprayer, upper and nether net board in the barrel. The foam room is between the two boards. The smoke inlet and outlet of foam clarifier are set on the upper and nether part. The dust outlet is set on the bottom of the barrel and connects with dust gathering box. There's an axis in the barrel which connects with the axis of the electromotor. The axis in the foam room connects some vanes; there's circular water box and clarifier box by the side of the barrel.

Description

technical field [0001] The invention relates to a flue gas purification device. Background technique [0002] At present, there are many ways to control smoke and dust, each with different characteristics. Among them, wet dust removal is a more common treatment method. Wet dust removal is to wash the dusty gas with water, and use the formed liquid film, liquid droplets or bubbles to capture the dust in the gas. Particles and dust particles are discharged with water, and the gas is purified. Liquid film, liquid droplets or bubbles mainly achieve the purpose of capturing dust particles in exhaust gas through inertial collision, diffusion of fine dust particles, condensation of liquid film and liquid droplets after humidifying dust particles and adhesion to dust particles . Bathing dust collectors in wet dust collectors include water bath dust collectors, foam dust collectors, impulse dust collectors and other forms. Their working principles are basically the same, which is t...
