Chimney-penetrating coal-transportation trestle and coal transportation system thereof

Abstract

The invention discloses a chimney-penetrating coal-transportation trestle and a coal transportation system provided with the chimney-penetrating coal-transportation trestle. The chimney-penetrating coal-transportation trestle comprises a chimney and a trestle, wherein the chimney comprises an inner barrel and an outer barrel, a supporting platform is arranged in the outer barrel, the inner barrel is sleeved in the outer barrel and placed on the supporting platform, a flue port which is communicated with the inner barrel is arranged on the side wall of the outer barrel, the supporting platform at the bottom is higher than the bottom of the outer barrel, and a cavity segment is formed at the bottom of the outer barrel; two open holes are arranged on the side wall of the cavity segment of the outer barrel, and the trestle penetrates through the two open holes. The invention can greatly lower the investment cost and has lower energy consumption in the production process.

Description

technical field [0001] The invention relates to a trestle for conveying coal through a chimney and a coal conveying system with a trestle for conveying coal through a chimney. Background technique [0002] Existing power plants need to be equipped with coal storage yards, desulfurization devices, electrostatic precipitators, side coal bunkers, boiler rooms, chimneys, and trestles. The connection of the coal yard forms the central axis, and there are two sets of desulfurization devices, electrostatic precipitators, and boiler rooms, which are respectively located on both sides of the central axis; the coal in the coal storage yard needs to be transported to the side coal bunkers through trestles. There is a chimney, and the trestle bridge cannot pass through. The current practice is: the trestle bridge needs to bypass the desulfurization device, the electrostatic precipitator and the chimney. The detour path is relatively long, and the investment cost increases. energy. Co...
