Coke oven door smoke sealing material and sealing method thereof

Abstract

The invention discloses a coke oven door smoke sealing material. The material contains main materials and additive materials, wherein the main materials comprise the following components in percentageby weight: 88%-92% of clay fireclay and 8%-12% of micro silicon powder; the additive materials comprise the following components based on the total weight of the main materials: 7%-12% of water glass, 15%-25% of asbestos wool and 0.1%-0.2% of a coagulant. A sealing method comprises the following steps: after a carbonization chamber of the oven door leakage number is filled with coal and a coal filling pore cover, a bridge tube turning plate and ammonia water pressure are restored to the normal production state, floating ash and impurities at positions of the fire door knife edge and a fire door frame gap are removed firstly, then the prepared sealing material is pressed into the gap by a flat jointing shovel for jointing, after the surface layer is full, the surface of the sealing material is flattened and scraped flat by a shovel, and the sealing material is smoothly connected with the knife edge and an oven door frame joint. The sealing material is reliable in sealing.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a coke oven door smoke sealing material and a sealing method thereof. Background technique [0002] The machine and coke sides of the coke oven carbonization chamber are closed by the furnace door. The leakage of the furnace door is one of the main pollution sources of the coke oven, and it is also the difficulty and focus of the control of unorganized emission of the coke oven. The main reason for the leakage of the furnace door is the furnace door There is a gap between the edge of the knife and the sealing surface of the furnace door frame, and the positive pressure of the carbonization chamber will cause a large amount of raw gas to escape from the gap of the edge of the knife, which will not only pollute the atmosphere, but also cause the gas to catch fire on the frame and pillar of the furnace, which will eventually cause the frame and The furnace column is deformed and ...

AI Technical Summary

Problems solved by technology

If these two materials are used as sealing materials, they will dry, shrink and crack soon after use. The furnace door is not well sealed, and the furnace door will still run out of smoke and fire or inhale air.

[0005] (2) Poor adhesion, easy to peel off

These two kinds of sealing materials are wiped in the edge seam of the furnace door and peel off due to poor adhesion, and cannot achieve the sealing effect.

[0006] (3) There are many pores and poor compactness

Because these two materials have more pores and poor compactness, cracks will occur after the materials are heated, and the sealing effect is poor
