Problems solved by technology

[0004] 1) The thermal radiation coefficient is small, resulting in low radiation heat transfer efficiency on the inner wall of the furnace;
[0005] 2) Under the long-term action of the high-temperature heat flow environment in the furnace, crystallization and pulverization occur from the surface to the inside, reducing the service life of the furnace wall
[0007] 1) Disadvantage of heat insulation performance, poor heat preservation effect, the thickness of the furnace wall needs to be increased by about about 50% In order to achieve the same thermal insulation effect as the ceramic fiber cotton furnace wall, it also increases the floor area of ​​the furnace, requires high construction requirements and consumes a lot of labor
[0008] 2) As the thickness of the furnace wall increases, the total volume of the furnace wall will also increase, resulting in a large heat capacity of the furnace wall. Therefore, the process of heating up the furnace and stopping the furnace to cool down not only wastes heat energy but also increases time-consuming, which hinders the normal production of the furnace
[0009] 3) After a certain number of years of service, cracks will appear, and the high-temperature flame in the furnace will burst out of the cracks, resulting in waste of heat energy
However, the blackbody element provided by the patent literature has the following defects: ① it occupies the space in the furnace and hinders the production operation; ② the blackbody element makes the inner wall of the originally flat furnace wall become substantially uneven, which reduces the radiation heat transfer and convective heat transfer in the furnace. effect, plus the material of the black body element and the adhesive are the existing technologies in this field, and there is no original contribution to improve the energy saving effect on the material

Abstract

The invention provides a modular structure wall body of a high-temperature heating furnace, and the modular structure wall body greatly increases a furnace wall inner wall radiation coefficient of thehigh-temperature heating furnace, obviously strengthens in-furnace heat transfer efficiency, achieves energy conservation and emission reduction, slows down a furnace wall ageing process, and prolongs the service life of a furnace wall. The modular structure wall body comprises a preset furnace wall main truss and a furnace top truss. The modular structure wall body is characterized in that corresponding connecting inverted-H-shaped steel is fixedly arranged on the bottom surface of the furnace top truss separately, wherein the bottom of the connecting inverted-H-shaped steel is connected with a top blocking structure of a hoisting outer screw; the hoisting external screw which is upwards bulged is uniformly distributed on the upper surface of a ceramic fiber cotton module; the ceramic fiber cotton module is mounted on the lower surface of the furnace top truss through the hoisting external screw; a gap is reserved in the lower surface of the connecting inverted-H-shaped steel; a ceramic fiber cotton felt spreads on a gap area between the ceramic fiber cotton module and the lower surface of the connecting inverted-H-shaped steel; and the lower surface of the ceramic fiber cotton module is fixedly equipped with a furnace wall inner protective liner.

Description

technical field [0001] The invention relates to the technical field of heating furnace structures, in particular to a modular wall of a high-temperature heating furnace. The invention also provides an installation method for the modular wall. Background technique [0002] At present, the furnace walls of ethylene cracking furnaces are mostly made of ceramic fiber cotton, and the furnace walls of high-temperature heating furnaces such as steel heating furnaces and ceramic heating furnaces are mostly composed of refractory bricks and high-temperature resistant castables. [0003] The walls of high-temperature heating furnaces such as ceramic fiber cotton, refractory bricks, and high-temperature resistant castables have the following common shortcomings: [0004] 1) The thermal radiation coefficient is small, resulting in low radiation heat transfer efficiency on the inner wall of the furnace; [0005] 2) Under the long-term action of the high-temperature heat flow environment...
