Embodiment 1

[0040] The quick overhaul construction method of CDQ furnace lining of the present invention comprises the following steps:

[0041] a. Formulate the construction process for the overhaul of CDQ furnace lining

[0042] figure 1 It is a flowchart of quick overhaul of CDQ furnace lining according to the embodiment of the present invention. The CDQ furnace lining overhaul construction process includes the following specific measures:

[0043] 1) Flat coke installation and protection platform in the furnace;

[0044] 2) Set up scaffolding for demolition of bricks:

[0045] 3) Remove the pre-storage part and cooling part;

[0046] 4) Remove the inclined air duct and the surrounding air duct:

[0047] 5) Masonry cooling part and inclined air duct;

[0048] 6) Masonry surrounding air duct and construction lower cone bucket;

[0049] 7) Masonry pre-storage department;

[0050] 8) Facilities dismantled.

[0051] b. Plan the vertical transportation method of materials

Abstract

Disclosed is a dry quenching shaft lining quick overhaul construction method. The dry quenching shaft lining quick overhaul construction method is characterized by comprising the following steps of a, formulating a dry quenching shaft lining overhaul construction process; b, planning a material vertically transporting rout: c, removing refractory bricks; d, laying refractory materials. The dry quenching shaft lining quick overhaul construction method is reasonable in repair process design and proper in measure; by means of the characteristics of separating the refractory materials of a dry quenching shaft lining through brick support plates between an inclined flue and a cooling unit as well as setting expansion gaps, the refractory bricks of a prestorage unit and the cooling unit can be removed simultaneously to accelerate processes; by setting up a bearing platform and a protecting platform, the refractory bricks of the cooling unit and the inclined flue can be laid simultaneously, and removing and laying glass-ceramic plates of a lower cone loader as well as laying the refractory bricks of a circulating flue can be implemented simultaneously. The dry quenching shaft lining quick overhaul construction method has the advantages of being safe and reliable in repair project quality and capable of reducing project costs, greatly saving the dry quenching shaft maintaining time and advancing production processes.

Description

technical field [0001] The invention relates to a construction method for overhauling a kiln, in particular to a rapid overhaul construction method for a CDQ furnace lining. Background technique [0002] The refractory lining of the dry coke quenching device is 5-6 years after the device is produced, due to various reasons, the refractory bricks in the cooling part, inclined air duct, ring air duct, pre-storage part and other parts will break and peel off, seriously affecting normal production. For this reason, the refractory materials in the cooling part, the inclined air duct, the surrounding air duct, and the pre-storage part, including the cast stone slabs in the lower cone bucket, were removed and rebuilt. However, using the known CDQ furnace lining overhaul construction technology, the CDQ furnace maintenance time is long, the repair speed is slow, time-consuming and labor-intensive, which greatly hinders the pace of re-entering production and seriously affects econom...
