Spraying dust removing device and haze preventing and treating device, and spraying device and spraying method of spraying dust removing device and haze preventing and treating device

Abstract

The invention discloses a spraying device. The spraying device comprises an axial flow spraying barrel assembly, a flow guiding assembly and a spraying assembly; the axial flow spraying barrel assembly comprises an air feeding power source and a spraying barrel; the flow guiding assembly comprises a flow guiding core body and a flow guiding plate; the flow guiding core body is fixed to the center of the spraying barrel through the flow guiding plate; the flow guiding core body is arranged in the air direction in the spraying barrel; the spraying assembly comprises an outer spraying assembly arranged at an air outlet of the spraying barrel and an inner spraying assembly arranged at the tail portion of the flow guiding core body; the outer spraying assembly is a single-ring-shaped spraying assembly or a dual-ring-shaped spraying assembly; and a single spray nozzle or double spray nozzles or a plurality of spray nozzles are adopted for the inner spraying assembly. The spraying device has the technical advantages of being wide in firing range and high in dust removing efficiency. In addition, the invention further provides a spraying method used for the spraying device, and a spraying dust removing device and a haze preventing and treating device comprising the spraying device or applying the spraying method.
