Problems solved by technology

The known method of building the regenerator wall and checker bricks is to build the main wall and single wall of the regenerator first, and then build the partition wall and checker bricks after the furnace top construction is completed. However, this construction method exists The construction space is small, there are many refractory materials involved (5 types), and the number of refractory bricks is large (up to more than 20 varieties), which is easy to be confused, and the quality of furnace masonry is not easy to control.
[0003] Therefore, there are above-mentioned inconveniences and problems in the known regenerator wall and checker brick masonry method.

Embodiment 1

[0031] see now figure 1 with figure 2 , figure 1 It is a top view of the grid regenerator of the coke oven according to the embodiment of the present invention, figure 2 It is a sectional view of the coke oven gridded regenerator according to the embodiment of the present invention. As shown in the figure, the main wall and the single wall of the gridded regenerator of the 7-meter coke oven have a total of 25 floors, from the 10A to the 34A; 24 layers of lattice bricks, and 26 layers of small horizontal partition walls;

[0032] 1. The main construction sequence is:

[0033] Build the main wall of the coke oven grid regenerator and the 10A~14A floors of the single wall→build the 1st~5th layer of small transverse partition walls→build the 1st~3rd layer of lattice bricks and take protective measures→build heat storage The main wall and single wall of the room on the 15th to 19th floors → build the 6th to 10th floors A to 1 small transverse partition walls → build the 4th t...

Abstract

The invention discloses a method for building a cellular regenerative chamber of a coke oven. The method is characterized by comprising the following steps of: a, building a main wall and a single wall of the regenerative chamber; b, building a small cross wall of the regenerative chamber; c, building lattice bricks; d, placing rubber skins and wood boards for protection; and e, repeating the steps a-d until the building design height of the cellular regenerative chamber of the coke oven is reached. The method for building the cellular regenerative chamber of the coke oven, disclosed by the invention, has the advantages of being reasonable in construction step design and simple in operation, changing a conventional building method, being large in construction space and orderly in management of refractory materials, being capable of immediately monitoring the building quality, being safe and reliable in project quality, increasing labor efficiency, greatly reducing the construction period and lowering the project cost.

Description

technical field [0001] The invention relates to a coke oven masonry method, in particular to a coke oven grid regenerator masonry method. Background technique [0002] In recent years, the coking industry has developed rapidly. As the main equipment for coking, the coke oven is also developing towards large-scale, environmental protection and automation. Large-scale coke oven regenerators over 7 meters are generally compartmentalized regenerators, and each vertical fire channel corresponds to two regenerators separately, and constitutes a heating unit, so that heating gas and air are distributed in the lengthwise direction of the regenerator Reasonable and even. Since the regenerator adopts a grid pattern, a small transverse partition wall is left in the regenerator chamber, and there is a groove on the position of the small transverse partition wall close to the single wall, and an expansion joint is reserved. The known method of building the regenerator wall and checker ...
