Abstract

The invention relates to a dust fall and leakage-proof intelligent system and method for a coal conveying belt of a thermal power plant. The dust fall and leakage-proof intelligent system comprises a self-circulation area, a humidifying chamber, leakage-proof baffles and a controller; the self-circulation area is arranged on a coal falling pipeline, two auxiliary pipelines are reversely connected with an outlet and an inlet of a main pipeline of the coal falling pipeline, the humidifying chamber is connected between the self-circulation area and the coal conveying belt, dust blocking curtains and the leakage-proof baffles are installed at the joints of the two ends of the humidifying chamber, and a dustproof atomizing nozzle is installed in the middle of the top of the humidifying chamber; and each of the inner side and the outer side of the dust blocking curtain at an outlet of the humidifying chamber is provided with a humidity sensor, the leakage-proof baffles are installed in the running direction of the coal conveying belt at equal intervals, pressure sensors are installed on the positions, corresponding to the leakage-proof baffles, of the coal conveying belt carrier rollers, the leakage-proof baffles are provided with dustproof atomization nozzles, and the controller has certain calculation capacity. Through the manner, the concentration of dust formed in the coal conveying process can be reduced, coal scattering pollution of the coal conveying belt can be prevented, and intelligent control over the coal conveying system is achieved.

Description

technical field [0001] The invention relates to the technical field of coal conveying system control, in particular to an intelligent system and method for dust reduction and leakage prevention of a coal conveying belt in a thermal power plant. Background technique [0002] Coal drop pipes and coal conveyor belt conveyors are the most seriously polluted areas during coal transportation in thermal power plants, mainly due to dust pollution caused by the large height drop of coal drop pipes and ground pollution caused by coal falling and coal scattering during coal transportation. The health of staff in the area poses a threat. [0003] The existing dust-proof means mainly include combining the dust-proof bag with the filter system or installing a fully-enclosed dust-proof cover. The main way to prevent the coal-conveyor belt from spreading coal is to install baffles along the entire coal-conveyor belt. [0004] These dust-proof and leak-proof devices are complex in structure...
