Double-annular-atomizing environment-friendly dust-removing pneumatic spraying machine

Abstract

The invention discloses a double-annular-atomizing environment-friendly dust-removing pneumatic spraying machine, which belongs to the technical field of the spraying machines. The pneumatic spraying machine is technically characterized by comprising a base, wherein a spraying mechanism is arranged on the base, and a turntable is arranged on the base and connected with a horizontal rotation driving device; a bracket is arranged on the turntable; the spraying mechanism is connected with the bracket and comprises an axial flow fan, a spraying drum and a double-annular atomizer; the axial flow fan, the spraying drum and the double-annular atomizer are connected with one another in sequence; the double-annular atomizer is connected with a high-pressure water pump by a pipeline; the high-pressure water pump is connected with an external water supply source by a pipeline and connected with an electric control box by a circuit; and the horizontal rotation driving device and the axial flow fan are respectively connected with the electric control box by circuits. The invention aims at providing the double-annular-atomizing environment-friendly dust-removing pneumatic spraying machine with compact structure, long range and better covering effect; and the double-annular-atomizing environment-friendly dust-removing pneumatic spraying machine is used for removing and suppressing dusts of dust pollution caused by mining in large-sized open pit coal mines as well as disorder dust discharge pollution in coal yards and during transportation, crushing and the like.

Description

technical field [0001] The invention relates to a sprayer, more specifically, to a double-circular atomization environment-friendly dust removal air-supply sprayer. Background technique [0002] With the rapid development of modern industry, coal-fired power plants, port terminals, coal mines, mines, chemical plants, steel plants and other raw material storage yards are very prone to excessive dust, which seriously affects the surrounding natural environment and the health of employees. The national environmental protection department has issued relevant regulations to control and restrict this aspect of pollution. [0003] At present, methods such as tap water spraying and dust-proof nets are commonly used to solve the dust problem in large material yards. Spraying with tap water wastes a lot of water, and excess water can lead to mineral loss and groundwater pollution. The dust-proof net can prevent the dust from polluting the materials outside the site, but it cannot re...
