Combined wet-type pipeline dedusting device

Abstract

The invention relates to a combined wet-type pipeline dedusting device. A first-stage dedusting system comprises a dedusting air duct I, a high-pressure spray nozzle, fan blades and a dirt removal channel, wherein the fan blades are connected on a motor, the motor is fixed to the inner wall of the dedusting air duct I, and the dirt removal channel is arranged at the bottom of the dedusting air duct I. A second-stage dedusting system comprises a dedusting air duct II, wherein an annular inclined pipeline is arranged in the dedusting air duct II, and spiral rotary pieces are arranged in the pipeline and connected on a fixing rod in the pipeline. A third-stage dedusting system comprises a dedusting air duct III, wherein a filter barrel is arranged in the dedusting air duct III, three wet-type filters are arranged in the filter barrel, and the filter barrel is connected on two shafts through a pair of connection tripods. The three dedusting air ducts are fixedly connected through bolt flange structures, and the whole dedusting system is fixed on the ground through fixing supports. The combined wet-type pipeline dedusting device has the advantages and the benifits that a multi-stage dedusting technique is adopted on the basis of existing inside spraying and outside spraying, an efficient dedusting purpose is achieved and the combined wet-type pipeline dedusting device is suitable for wide popularization and application in a mine.

Description

technical field [0001] The invention relates to a dust removal system, in particular to a combined wet pipeline dust removal device. Background technique [0002] In recent years, the rapid development of my country's industry has caused the continuous deterioration of the environment, and dust is the main pollutant causing environmental problems. Among the four major occupational hazards in my country's mining enterprises (work-related injuries, dust, poisons, and explosions), the most serious one is dust hazards. The dust is inhaled by workers, and after a certain amount is deposited in the respiratory system, it will lead to the occurrence of pneumoconiosis. The dust reduction effect of the internal spray, external spray and foam dust removal currently used in China is relatively poor and has failed to meet the national standard. The dust removal method used to suck the dust gas to the back of the roadway is only to transfer the dust generated on the working surface to o...

AI Technical Summary

Problems solved by technology

The dust reduction effect of the internal spray, external spray and foam dust removal currently used in China is relatively poor and has failed to meet the national standard. The dust removal method used to suck the dust gas to the back of the roadway is only to transfer the dust generated on the working surface to other places. place, the dust has not been fundamentally removed

Although foreign dust removal technology and equipment can meet certain requirements in dust removal effect, the introduction cost is relatively high, and some dust removal equipment cannot meet the performance requirements due to the small excavation section area.
