Embodiment 1

[0041] A method for cleaning the coke oven chute in the present embodiment consists of the following steps:

[0042] 1. Preparatory work

[0043] (1) According to different coke oven models, transport the required checker bricks to the coke oven area in advance and place them in the drying area of ​​the second floor of the coke oven or the end platform;

[0044] (2) Prepare fiber felt and asbestos felt insulation materials, and prepare 3 to 4 sets of heat insulation clothing;

[0045] (3) Prepare the tools needed for cleaning;

[0046] 2. Cooling treatment

[0047] (1) Set up the carbonization chamber and buffer furnace of the braising furnace: when one of the ramps of the coke oven combustion chamber needs to be cleaned, according to the characteristics of the double-connected fire channel, if the combustion chamber where the ramp is located has two eyes, the combustion chamber The previous carbonization chamber adjacent to the braising furnace is set as the braising furna...

Abstract

The invention relates to a method for cleaning a coke oven chute and belongs to the method for cleaning the coke oven chute, aiming at solving the technical problems in an existing method for treating blocking of a chute of a coke oven that the working amount is great, damages to a furnace wall are great and the service life of the coke oven is influenced. The method for cleaning the coke oven chute, provided by the invention, comprises the following steps: 1, doing early-stage preparation work; 2, carrying out cooling treatment; 3, dredging the coke oven chute; 4, carrying out temperature rising treatment and recovering production. According to the method for cleaning the coke oven chute, the chute is cleaned from the top of a heat storage chamber from bottom to top and the working safety is improved; damages to silicon bricks of the furnace wall of a carbonization chamber are not caused by temperature lowering and temperature rising, and the silicon bricks of the furnace wall are not broken; after treatment, a flame path of a combustion chamber can be smoothly ignited and waste gas is discharged, so that the requirement of uniformly heating the coke oven is met.

Description

technical field [0001] The invention relates to a method for cleaning coke oven chute, which belongs to a method for cleaning coke oven chute blockage. Background technique [0002] The coke oven is the most important and critical equipment in the coking plant, with a large investment and a design life of more than 25 years. However, with the increase of the age of the coke oven, the aging of the masonry, the impact of long-term mechanical force, frequent opening and closing of the furnace door during operation, cold air erosion, sudden change in temperature, and thermal stress, the surface of the silicon brick in the carbonization chamber appears denuded and chipped. , the furnace wall has cracks, the strength of silica bricks is reduced, broken bricks and mud fall into the combustion chamber, and then mixed with coal ash accumulated in many years of production, resulting in blockage in the chute area, obstructed air flow, and air cannot reach the combustion chamber smoothl...
