Problems solved by technology

[0006] (2) Large coke output
[0008] (4) The furnace body is strong, compact, slow aging, and long furnace life
[0015] There are still some disadvantages in the existing coking technology: small amount of coke output, low shrinkage, poor quality and low hardness
The coke oven proposed in this patent has a two-stage heat exchange structure, which changes the coking process of the traditional coke oven. At the same time, there are some problems: small coke output, difficult coke pushing, low coke shrinkage rate, low density and hardness
The sealing wall of the regenerator and the chute is not tight, the heat loss is large, and the temperature of the furnace roof, basement and flue corridor is high

Embodiment 1

[0035] In the coking process, the total length of the carbonization chamber is 15980mm, and the effective length is 15100mm. The average width of the carbonization chamber is 620mm, the overall height is 5505mm, and the effective height is 5200mm. Taper 70mm. The center distance of the carbonization chamber is 1420mm, and the effective volume of the carbonization chamber is 44.7 cubic meters. The sealing wall of the regenerator and the furnace head of the chute are made of light clay insulation bricks, insulation coatings, calcium silicate slabs and insulation coatings on four layers from the inside to the outside. The main film-forming substance of thermal insulation coating is sepiolite, and the filler is expanded perlite. The heating level is 1100mm. The number of fire channels in each combustion chamber is 32. The center distance of the combustion chamber is 480mm, and the design coking time is 26h. The coke oven column is made of H-shaped steel. Bead bricks are laid...

Abstract

The invention relates to the field of metallurgy coking, particularly to a coking technical method. A coke oven used in the method adopts a wide carbonization chamber, and the width of the carbonization chamber is 620mm. The wide carbonization chamber used in the method and the heating level can cause the yield of coke to be increased, and the shrinking percentage and the intensity of the coke are improved. The sealed wall of a heat storage chamber and the position of the oven head of a chute are made of compound thermal insulation materials, floating bead bricks are paved at the oven bottom of the coke oven, so that the tightness of the heat storage chamber and the chute can be improved.

Description

[0001] technical field [0002] The invention relates to the field of metallurgical coking, in particular to a coking process method. Background technique [0003] Coking coal is processed through the coking process to produce coke, coke oven gas and coking chemical products. Coke is the main product of coking and an important source of energy for the metallurgical industry. my country's coke production, consumption and export rank first in the world. The difficulty lies in improving the coking process, improving and stabilizing the coke quality. [0004] The coking process should meet the following requirements: [0005] (1) Production of high-quality coke. The coke oven can be heated evenly, the coke cake is heated uniformly in the long and high directions, and the heating level is appropriate to reduce the cracking loss of chemical products. [0006] (2) Large coke output. In order to improve the production capacity of the coke oven, high-quality refractory material...
