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

Abstract

The invention discloses a water mist dust falling and material guide device and a dust falling method. A lot of coal dust is produced in a coal transportation process. The water mist dust falling and material guide device comprises a material guide trough (5), wherein multiple coal falling devices (1) are mounted on the material guide trough; a pressure reduction device (15) is mounted at the left end of each coal falling device; electrostatic sealing curtains (4) are mounted between every two adjacent coal falling devices and at two ends of all the multiple coal falling devices; a water mist dust remover (8) is mounted at the right end of the material guide trough; each pressure reduction device consists of a first-stage pressure reduction box (6), a second-stage pressure reduction box (7) and two pressure reduction box water mist dust removers (30); the second-stage pressure reduction boxes are mounted on the first-stage pressure reduction boxes; and the two pressure reduction box water mist dust removers are respectively mounted on each first-stage pressure reduction box and each second-stage pressure reduction box. The invention is applied to the water mist dust falling and material guide device and the dust falling 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...
