Chimney glass fiber reinforced plastic inner tube fast installation method

Abstract

The invention provides a chimney glass fiber reinforced plastic inner tube fast installation method. The method includes the steps that a hoisting device is arranged on the top of a chimney; chimney glass fiber reinforced plastic inner tube segments arranged on the ground are hoisted to the top of the chimney through the hoisting device; the chimney glass fiber reinforced plastic inner tube segments hoisted to the top of the chimney are lowered to the interior of the chimney from a smoke outlet in the top of the chimney through the hoisting device; fast installation joints arranged between the top ends and the bottom ends of the chimney glass fiber reinforced plastic inner tube segments are used for sequentially connecting the adjacent chimney glass fiber reinforced plastic inner tube segments in an end-to-end mode; the steps are repeated till all the chimney glass fiber reinforced plastic inner tube segments are installed in the chimney. Due to the fact the hoisting device is arranged on the top of the chimney and the chimney glass fiber reinforced plastic inner tube segments are hoisted into the chimney and connected, a chimney glass fiber reinforced plastic inner tube can be transported and managed conveniently, installing difficulty is reduced, engineering time is shortened, and installing efficiency and safety of the chimney glass fiber reinforced plastic inner tube are improved.

Description

technical field [0001] The invention relates to the technical field of chimney construction, in particular to a method for quickly installing a glass fiber reinforced plastic inner tube of a chimney. Background technique [0002] In my country's energy structure, the burning of coal accounts for more than 70%, resulting in several severe acid rain areas in my country's economically developed areas, seriously destroying the natural environment we depend on for survival. In order to solve this environmental problem, my country has implemented coal-fired power plant flue gas desulfurization nationwide since 2002, most of which are wet flue gas desulfurization processes represented by the limestone-gypsum method, and the general desulfurization efficiency is acceptable. Reach more than 95%. [0003] Due to the addition of the wet flue gas desulfurization process, the flue gas discharge temperature has dropped from 130°C before desulfurization to 45-55°C, and the moisture content...

Problems solved by technology

[0004] In the existing technology, the installation of the chimney or the addition of the chimney is all done by hoisting the whole chimney. In this case, the transportation cost is high, the installation is difficult, and the operation time is long, which cannot meet the industrial needs.
