Embodiment Construction

[0014] Such as figure 1 As shown, the three-stage dust removal and desulfurizer described in the embodiment of the present invention includes a cyclone cylinder 1, a flow deflector 2 and a filter 5, the top port of the cyclone cylinder 1 is connected to the flow deflector 2, and the cyclone cylinder 1. The upper part is funnel-shaped and is provided with a Venturi throat 8. The bottom of the swirl tube 1 is provided with a settling tank 10 and communicates with the sewage chamber 17 below; An atomizing nozzle 7 is arranged on the inside of the tuyere 3 and in the air duct above the Venturi throat 8, and the two atomizing nozzles 7 are connected to the dosing box 6 outside the cyclone 1; the cyclone 1 above the air inlet 3 A speed brake 9 is horizontally laid in the interior. The interior of the deflector 2 is arranged in a staggered manner from top to bottom with a number of obliquely arranged deflectors 12 and together form several layers of stepped structures in the inner c...

Abstract

The invention relates to a three-stage dust removal and desulphurization device. The device comprises a swirling drum, a guiding device and a filter, wherein a port at the top of the swirling drum is connected with the guiding device, a Venturi throat is arranged on the swirling drum, an air inlet is formed in the outer side of the swirling drum, and atomizing spray heads are arranged on the inner side of the air inlet and in an air flue above the Venturi throat respectively; a plurality of inclined guiding plates are arranged in the guiding device from top to bottom in a staggered manner, and three to five filter layers are sequentially arranged in the filter from bottom to top. The device has the benefits as follows: during dust removal and desulphurization, drugs are added twice through spraying to be fully mixed with gas to have a reaction, three-stage filtration is performed, so that the desulphurization effect can be obviously improved, and meanwhile, energy conservation and emission reduction can be greatly facilitated; the device has the characteristics of smaller size, convenience in maintenance, low usage cost, low power consumption, low water consumption, higher expansibility and the like and can be widely applied to dust removal and desulphurization of air pollution caused by industrial waste gas, blast-furnace gas, boiler flue gas and the like as well as treatment of other harmful gases.

Description

technical field [0001] The invention relates to a dedusting and desulfurizing device for gas such as flue gas, dust, tail gas and harmful gas generated in the industrial production process, in particular to a three-stage dedusting and desulfurizing device. Background technique [0002] For industrial producing countries, a large amount of industrial tail gas is produced every year, causing a sharp deterioration of the social environment, and at the same time causing great harm to the ecological environment and living environment, directly or indirectly causing "acid rain" and climate warming in recent years. At present, environmental protection in various countries, especially the treatment of industrial tail gas and dust, is also continuously strengthened. Environmental protection companies currently use a variety of processes for the treatment of industrial tail gas, but the common problems are large energy consumption and water consumption. Large, large area, large invest...
