The invention discloses a zero-meter ground water drainage system of a single-tube chimney and an application method of the zero-meter ground water drainage system. The problem that the existing zero-meter water drainage system of a single-tube chimney cannot drain water smoothly is solved. The zero-meter ground water drainage system comprises a left ground (5) and a right ground (6), wherein the left ground (5) and the right ground (6) are respectively arranged on two sides of a horizontal longitudinal axis (2) of the ground in a chimney tube, and are inclined towards the outer side of the chimney tube by a gradient of 2%; an entrance ground (4) is arranged on the inner side of an entrance of a manhole door (3); arc-shaped water drainage ditches (7) with arc-shaped overflow weirs (8) are arranged on the ground of the inner side of a wall of the single-tube chimney tube (1); and two overflow ridges (10) are respectively arranged in the arc-shaped water drainage ditches (7) on two sides of a water inlet of a water drainage tube (9). The zero-meter ground water drainage system is reasonable in structure, clear in function, easy to construct and convenient to operate and maintain; and the quality is guaranteed easily.
Description
technical field [0001] The invention relates to a zero-meter ground drainage system for a chimney, in particular to a zero-meter ground drainage system for a single-tube chimney and a construction method thereof. Background technique [0002] Single-tube chimneys are widely used for their simple construction, short construction period and low cost. However, with the adoption of the wet desulfurization process in coal-fired power plants and the cancellation of the bypass flue and flue gas heating system, the temperature of the flue gas discharged from the single-tube chimney has been greatly reduced, and it has basically remained at about 50 °C. In addition, when the flue is arranged at a high level, the ash accumulation platform poses a great hidden danger to the overall anti-corrosion and anti-seepage of the chimney, and the elimination of the ash accumulation platform has become a mainstream trend. Therefore, the condensed acid water of a large amount of low-temperature f...
