Water mist dust falling and material guide device and dust falling method

Abstract

Water mist dust reduction material guide device and dust reduction method. During the transportation of coal, a large amount of coal dust will be generated. The composition of the present invention includes: a material guide trough (5), on which a plurality of coal dropping devices (1) are installed, and a decompression device (15) is installed on the left end of each of the described coal dropping devices, Electrostatic sealing curtains (4) are installed between the plurality of coal falling devices and at both ends of the plurality of coal falling devices, and a water mist dust collector (8) is installed at the right end of the guide chute. The decompression device is composed of a primary decompression box (6), a secondary decompression box (7) and two decompression box water mist dust collectors (30), and the secondary decompression box is installed on On the first-stage decompression box, two of the decompression-box water mist dust collectors are respectively installed on the first-stage decompression box and the second-stage decompression box. The invention is used for a water mist dust reduction material guide device and a dust reduction method.

Description

Technical field: [0001] The invention relates to the technical field of a coal conveying system, in particular to a water mist dust reduction material guide device and a dust reduction method. Background technique: [0002] Thermal power plants use coal-fired boilers, which need to burn a large amount of coal every year. The coal has to go through a series of transportation and processing processes from entering the plant to entering the boiler for combustion. These processes will generate a large amount of coal dust, and the airtight cover of the airtight, ventilated and dust removal system should be installed. Ventilation duct. Fans and related accessories require a total investment of one million yuan to solve the phenomenon of powder leakage in the material guide groove. The efficiency of dust removal is low and it takes a lot of time. It is difficult for workers to wear several layers of masks to prevent dust from entering the human body and pollution. It not only pos...
