Single-barrel type concrete chimney structure with thermal insulation and anti-corrosion layer

Abstract

The invention provides a single-barrel type concrete chimney structure with a thermal insulation and anti-corrosion layer. The single-barrel type concrete chimney structure comprises a concrete single barrel. The single-barrel type concrete chimney structure is characterized by furthering comprising a thermal insulation and anti-corrosion layer comprising a bottom coating, an adhesive and glass bricks, the inner wall of the concrete single barrel is coated with the bottom coating, and the glass bricks are attached to the bottom coating through the adhesive. By the use of the single-barrel type concrete chimney structure, the corrosion problem of the chimney caused by the wet smoke after desulfuration of coal-fired power plant is solved. The single-barrel type concrete chimney structure is simple in structure and low in cost. Besides, through the adhesive and the glass bricks, thermal insulation and anti-corrosion functions are achieved.

Description

Technical field [0001] The invention relates to a chimney structure, in particular to a single-tube concrete chimney with an anti-corrosion lining layer. Background technique [0002] As the main force in my country’s power industry, thermal power generation accounts for more than 80% of my country’s total power generation. With my country’s sustainable development strategy, all industries in my country are vigorously promoting energy conservation and emission reduction. Energy saving and emission reduction are even more important for thermal power plants. More than half of my country's total coal is consumed by thermal power plants. While consuming so much coal production, it has also caused serious pollution to my country's ecological environment. [0003] Environmental protection and energy saving is an important sustainable development policy of the country. With the development of my country's power industry, coal-fired units have entered the development stage of large units,...
