Description
Technical Field
The invention relates to an integral self-supporting glass fiber reinforced plastic inner cylinder supporting device which is arranged in a smoke port area and belongs to the technical field of chimney design and construction.
Background
Wet desulfurizing technology has been implemented in China for more than ten years, and Mahonia is a standing for the guard war in blue sky. The flue gas discharged by the wet desulfurization is wet flue gas, a chimney for discharging the wet flue gas is wet chimney, and the wet flue gas has serious corrosion effect on the wet chimney. Through the practice and experience summary of chimney anticorrosion for many years, the adoption of the glass fiber reinforced plastic inner cylinder is considered as an ideal scheme for wet chimney anticorrosion at home and abroad. The scheme is implemented by transforming the original common single-cylinder reinforced concrete chimney into a sleeve type reinforced concrete chimney with an outer cylinder being a reinforced concrete cylinder wall and an inner cylinder being a glass fiber reinforced plastic form.
The adoption of the suspension type glass fiber reinforced plastic inner cylinder is a common scheme for newly-built sleeve chimneys. However, for the anti-corrosion modification of the existing chimney, a 'suspension' glass fiber reinforced plastic inner cylinder is adopted, and a plurality of technical barriers exist. The main appearance is that: the existing chimney design standard does not meet the requirement of a 'suspension' inner cylinder chimney; the carrying capacity or design configuration does not meet the requirements; the upper part of the existing chimney is corroded and damaged, which is not beneficial to implementation of a suspension scheme; the size of the hole of the chimney bottom flue hole or the chimney manhole does not meet the transportation requirement of the glass fiber reinforced plastic inner cylinder. For the above reasons, if an integral self-supporting glass fiber reinforced plastic inner cylinder is adopted, and is hoisted at the top of the chimney and connected with the top opening of the chimney, the above difficulties are completely overcome.
However, because the opening size of the glass fiber reinforced plastic inner cylinder is large in the smoke gate area, the bearing capacity of the inner cylinder is greatly weakened, so that the glass fiber reinforced plastic inner cylinder cannot realize the whole self-standing in the true sense, and the inner cylinder (or flue) in the smoke gate area is usually required to be connected with the upper inner cylinder through an expansion joint, namely: the inner cylinder (or flue) in the smoke gate area is self-supporting, and the inner cylinder at the upper part of the smoke gate is self-supporting and connected by an expansion joint. The disadvantages of this embodiment are mainly: the inner cylinder vertically needs an expansion joint, so that the subsequent maintenance cost is increased; the upper glass fiber reinforced plastic inner cylinder needs an independent bearing and supporting system, so that the engineering cost and the construction period are increased; the inner cylinder (or flue) in the flue area is often made of manual pasting glass fiber reinforced plastic, and the quality is unreliable.
