Oven column applied to heat recovery coke oven

Abstract

The invention belongs to the field of building of heat recovery coke ovens, and particularly relates to an oven column applied to a heat recovery coke oven. A vertical frame structure of the oven column is characterized by comprising a frame body, adjusting spring assemblies, an upper brace connecting device and a lower brace connecting device, wherein the upper brace connecting device is arranged at the top of the frame body, the lower brace connecting device is arranged at the bottom of the frame body, and a plurality of the adjusting spring assemblies are arranged on the middle section of the frame body; the frame body is formed by connecting the middle portions of two pieces H-shaped steel with the same height and a plurality of double-angle steel cross beams; and each adjusting spring assembly comprises an adjusting spring and a screw rod, the adjusting spring faces the outer side of the frame body, and the screw rod faces the inner side of the frame body. The oven column of the invention has the advantages that 1) a distance between an upper transverse brace and the high-temperature furnace end is increased, the springs and the brace are prevented from being damaged by high temperature; 2) a lower transverse brace can better protect the lower part of the coke oven against thermal expansion force; and 3) the environmental protection grade of the coke oven is improved, and the service life of the coke oven is prolonged.

Description

technical field [0001] The invention belongs to the field of heat recovery coke oven masonry, in particular to an oven column applied to a heat recovery coke oven. Background technique [0002] During the coking production process of the coke oven, due to the high temperature, the expansion force is generated, which acts on the furnace wall, causing the coke oven to generate transverse stress, longitudinal stress and vertical stress. Because the furnace wall is built with refractory bricks, the stress bearing capacity is low, so the furnace wall is easily damaged. In order to protect the coke oven from being damaged, the protective plate is generally fastened at the furnace head of the furnace wall, and the furnace column is arranged outside the protective plate. The furnace protection pressure is applied in the side direction of the machine coke. The coke oven is protected from damage under the action of furnace protection equipment such as furnace pillars, protective pla...

AI Technical Summary

Problems solved by technology

The existing problem is: due to the installation of springs and other components for fixing the horizontal braces on the upper outside of the furnace column, because it is at the furnace head, it is prone to high temperature creep due to high temperature baking and high temperature raw gas escaping from the carbonization chamber. In addition, long-term coal charging and coke pushing at the furnace head will generate a large amount of dust, which will be adsorbed on the spring and cause corrosion; generally a spring sleeve is installed on the spring to prevent dust from adhering, and its side effect is to make the spring’s pulling force It cannot be adjusted normally, so it affects the curvature adjustment of the furnace column, so that the furnace wall cannot be reliably protected
