Thermal-state non-stop production replacement method of lattice bricks in regenerative chamber of coke oven

Abstract

The invention relates to a thermal-state non-stop production replacement method of lattice bricks in a regenerative chamber of a coke oven. The method comprises the following steps: dismantling a coke blocking plate in a chute region at the part where a lattice brick needs to be replaced, part of sealing walls of the regenerative chamber and ancillary facilities thereof, and carrying out insulation treatment near the dismantling region; inserting the front end of a slide way into the bottom of the lattice brick needing to be replaced, hooking a through hole in the lattice brick needing to be replaced by adopting a brick hooking device, moving the lattice brick needing to be replaced out of the regenerative chamber along the slide way, then pushing a new lattice brick into the regenerative chamber by adopting the same method, and putting the new lattice brick in place; and re-building the sealing walls of the regenerative chamber, and recovering the facilities in the chute region. According to the invention, the slide way, the brick hooking device, a brick lifting device and other special tools are used for replacing lattice bricks, and the operation can be executed outside the regenerative chamber by operators, so that the construction is convenient and fast and the safety is high; and the lattice bricks are not easy to be broken, so that the problem of blockage of a lower layer of lattice bricks caused by replacing an upper layer of lattice bricks is avoided, the hot repair cost is greatly saved, and the hot repair difficulty is reduced.

Description

technical field [0001] The invention relates to a method for replacing checker bricks in a regenerator of a coke oven, in particular to a method for replacing the checker bricks in a regenerator of a coke oven in a hot state without stopping production. Background technique [0002] During the use of the coke oven, the checker bricks on the upper layer of the regenerator are easily eroded, which in turn causes the blockage of the upper checker bricks, resulting in an increase in the resistance of the regenerator, which directly affects the adjustment of the corresponding combustion chamber horizontal row temperature and burner temperature. In case of serious blockage, there will be problems such as insufficient gas supply, and excessive gas leakage from the waste gas switch and the sealing wall of the regenerator, which will affect the normal production of the coke oven and the personal safety of employees. [0003] In order to maintain the normal production of the entire co...

Problems solved by technology

[0004] The invention provides a non-stop replacement method for checker bricks in a regenerator of a coke oven. Special tools such as slides, brick hooks and brick lifters are used to replace checker bricks. Operators can operate outside the regenerator, and the construction is convenient. Quick and high safety; checker bricks are not easy to break, avoiding the problem of blockage of the lower checker bricks when replacing the upper checker bricks, greatly saving the cost of hot repair and reducing the difficulty of hot repair
