Dust and waste gas treatment device

Abstract

The invention discloses a dust and waste gas treatment device which mainly comprises a supporting seat, a lower housing, an upper housing and a base, wherein the supporting seat is arranged on the base; both the lower housing and the upper housing are semi-round cavities and are welded to form a housing; a motor arranged on the supporting seat is connected with a transmission shaft; the transmission shaft penetrates through the center of the housing and is arranged on the supporting seat through a fixing seat; rotary wheels and fixed rings are arranged in the housing; the rotary wheels are connected with the transmission shaft through a transmission device; the fixed rings are arranged on the housing; the rotary wheels and the fixed rings are radially arranged in a staggered manner; rotary blades and fixed blades are arranged on the axial rods of the rotary wheels and the fixed rings respectively; positions of solvent nozzles formed in the housing correspond to those of the rotary blades in the radial direction. According to the dust and waste gas treatment device, dust and waste gas are synchronously treated, equipment is compact, the occupied area is small, the daily operation and maintenance costs are low, the equipment is easy to operate, a process is easy to perform, the dust treatment efficiency can reach more than 99%, and the content of dust in discharged gas is less than 100 mg / m<3>.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and in particular relates to a dust waste gas treatment device. Background technique [0002] In the production process of boiler flue gas, ferroalloy smelting, ore sintering, calcium carbide production and other industries, harmful exhaust gases such as sulfur dioxide, nitrogen oxides, and fluorine-containing gases are discharged, and a large amount of dust is discharged into the environment along with the exhaust gas, causing ambient air pollution. , with the improvement of national environmental protection standards and environmental protection requirements in recent years, in the above-mentioned polluting industries, no single exhaust gas or dust standard is used as the environmental protection standard requirement, but the dust and the generated waste gas must meet the corresponding standard requirements at the same time. To protect the environment, the dust emission requirem...

Problems solved by technology

[0003] At present, most of the treatment methods for this kind of dust waste gas use the process of multi-stage joint treatment to carry out environmental protection treatment of dust and waste gas generated by flue gas polluting enterprises, that is, the treatment of waste gas and dust is generally carried out in different treatment systems. Although the process of segmented multi-stage combined treatment achieves the purpose of treating waste gas or dust up to the standard, the area occupied by the treatment device is enlarged, the operation and management are inconvenient, the equipment investment cost is large, the treatment process is long, and the treatment cost is high. In addition, in the present In some dust treatment processes, due to the limitation of equipment structure and treatment effect, it is difficult to reach 100mg / m 3 emission standards
