Embodiment

[0023] Such as figure 1 As shown, it is a partial cross-sectional view of a brick sleeve chimney structure containing an insulation and anticorrosion layer. The brick sleeve chimney structure containing an insulation and anticorrosion layer includes a brick sleeve 1 and an insulation and anticorrosion layer. The insulation and anticorrosion layer It consists of an undercoat, an adhesive and a glass brick 2, the undercoat is coated on the inner wall of the brick sleeve, and the glass brick 2 is attached to the undercoat through the adhesive.

[0024] Described undercoat is selected as high adhesion undercoat (provided by Shanghai Dehao Chemical Co., Ltd. ); the adhesive is acid-resistant elastic adhesive (provided by Shanghai Dehao Chemical Co., Ltd. ); the glass bricks are made of light-weight thermal insulation glass foam bricks.

[0025] The manufacturing process of the single-tube concrete chimney structure containing thermal insulation and anti-corrosion layer is as fo...

Abstract

The invention provides a brick sleeve type chimney structure with a thermal insulation and anti-corrosion layer. The brick sleeve type chimney structure comprises a brick sleeve. The brick sleeve type 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 brick sleeve type chimney structure, the corrosion problem of the chimney caused by the wet smoke after desulfuration of coal-fired power plant is solved. The brick sleeve type 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 brick sleeve chimney with an anti-corrosion inner lining. Background technique [0002] As the main force in my country's electric power industry, thermal energy power generation accounts for more than 80% of my country's total power generation. With the proposal of my country's sustainable development strategy, all walks of life 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 output, it has also caused serious pollution to my country's ecological environment. [0003] Environmental protection and energy conservation are an important sustainable development policy of the country. With the development of my country's electric power industry, coal-fired units have...
