Improvement method for laying of corbel pillar bricks of coke dry quenching furnace

Abstract

The invention relates to an improvement method for laying of corbel pillar bricks of a coke dry quenching furnace. The improvement method is characterized by comprising the following steps of: a, investigation and analysis of the breakage of the corbel pillar bricks of the coke dry quenching furnace; and b, laying improvement of the corbel pillar bricks of the coke dry quenching furnace: (1) material improvement of the corbel pillar bricks of the coke dry quenching furnace and (2) laying structure improvement of the corbel pillar bricks of the coke dry quenching furnace. The improvement method for the laying of the corbel pillar bricks of the coke dry quenching furnace, disclosed by the invention, has the advantages that the difficult problem that the corbel pillar bricks of the coke dry quenching furnace are frequent to break, the service life of the corbel pillar bricks is prolonged, the room-temperature pressure-resistant strength is high, the high-temperature rupture strength is high, the engineering cost is reduced, and the production time of the coke dry quenching furnace is prolonged.

Description

technical field [0001] The invention relates to a method for building a CDQ furnace corbel, in particular to an improved brick masonry method for a CDQ furnace corbel. Background technique [0002] Dry coke quenching is an advanced technology in coking production, which has the functions of saving energy, reducing consumption and protecting the environment, and at the same time can improve the quality of coke. Dry coke quenching is more and more widely used. [0003] CDQ furnace is the main equipment for dry coke quenching. From the point of view of maintenance parts, the refractory material of CDQ furnace is the key part of the corbel. On the one hand, the supporting bricks of the corbel must bear the pressure of the upper partition wall and the internal refractory material of the ring air duct. Weight (about 220-260t); on the other hand, the working environment of the corbel refractory is harsh, and it has been affected by temperature fusion, rapid cooling and rapid heati...

Problems solved by technology

[0003] CDQ furnace is the main equipment for dry coke quenching. From the point of view of maintenance parts, the refractory material of CDQ furnace is the key part of the corbel. On the one hand, the supporting bricks of the corbel must bear the pressure of the upper partition wall and the internal refractory material of the ring air duct. Weight (about 220-260t); on the other hand, the working environment of the corbel refractory is harsh, and it has been affected by temperature fusion, rapid cooling and rapid heating, strong air flow, coke friction, chemical corrosion, etc. The breakage of the pillar brick at the leg is the bottleneck of the life of the refractory material of the entire CDQ furnace body, and the life span is only about 1 year

[0004] Therefore there is above-mentioned inconvenience and problem in known CDQ furnace corbel pillar brick
