A carbonization furnace wall gunning device and method

Abstract

The invention discloses a carbonization furnace wall spray repair device and method belonging to the technical field of coke making. In the carbonization furnace wall spray repair device, one end of a positioning mechanism is movably arranged in a sliding chute; a high-temperature imaging instrument is arranged at the other end of the positioning mechanism; a closing plate is arranged at the other end of the positioning mechanism; one end of a purging mechanism is arranged on a coke leveling vehicle, and the other end is arranged on one side of the closing plate; one end of a refractory mortar conveying mechanism is arranged on the coke leveling vehicle, the other end is communicated with the closing plate, and the refractory mortar conveying mechanism is communicated with one end of the purging mechanism; and a programmable logic controller is connected with the positioning mechanism, the high-temperature imaging instrument, the purging mechanism, the refractory mortar conveying mechanism and the coke leveling vehicle. According to the carbonization furnace wall spray repair device and method, artificial high-temperature repair work in a carbonization chamber can be replaced, thus effectively relieving the labor intensity and ensuring the production safety; and no cooling treatment is needed, thus shortening the repair time, ensuring the production rhythm and being beneficial to the long service life of a carbonization chamber walling.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a carbonization furnace wall gunning device and method. Background technique [0002] Top-charging coke oven coking is the main way to produce coke for blast furnace ironmaking in my country. In the actual production process of the coke oven, with the increase of the age of the furnace, as well as the temperature stress, mechanical pressure and chemical corrosion caused by operations such as coke pushing, coal charging, and door removal, the various parts of the furnace body gradually change, and the furnace wall There are different degrees of cracks, denudation, pitting, corner drop, deformation, wrong platform, melting hole and even turning on the surface. This will cause the two chambers to collude, that is, the coke, coal materials, and raw coal gas in the carbonization chamber will enter the adjacent combustion chamber or flue when coke is pushed and charged, which will affe...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a carbonization furnace wall gunning device and method, which solves or partly solves the problem of repairing the carbonization chamber in the prior art, which causes the temperature to be too high and is suitable for manual operation, and the content of gas and toxic gases in the carbonization chamber seriously exceeds the standard. It is beneficial to construction. When the temperature of the silica brick material used in the carbonization chamber is too low, the silica brick has undergone lattice transformation, which may cause shrinkage and settlement of the hole in the wall, which will cause the wall to burst and expand the technical problem of digging and repairing.
