Problems solved by technology

Coal is subjected to high-temperature dry distillation in the carbonization chamber. Over time, graphite will grow and adhere to the furnace wall of the carbonization chamber. Leakage, deformation and other consequences have a great impact on coking production
[0003] In the prior art, the cleaning of graphite on the furnace wall of the carbonization chamber adopts the original manual cleaning method, that is, after discovering that the furnace wall has accumulated graphite, manually use a 6-meter-long spatula to aim at the graphite and remove it. On the one hand, it is time-consuming and laborious; on the other hand, On the one hand, the cleaning effect is not good, especially for the graphite in the middle of the carbonization chamber, it is necessary to stand on the furnace roof, insert the spatula into the coal inlet, and then clean the graphite on the furnace wall, which poses a great safety risk

Embodiment Construction

[0029] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The object of the present invention is to provide a special graphite cleaning device and cleaning method for the furnace wall of the coke oven carbonization chamber. Through the device and method, the graphite of the furnace wall of the carbonization chamber can be removed quickly, effectively and safely.

[0031] This technology uses an air compressor with an output pressure of 0.7-1.0MPa, a feeding device, a spray gun, corresponding compressed air purge pipelines, gunning materials, control systems and other equipment to realize the cleaning and carbonization of graphite on the furnace wall of the carbonization chamber. Chamber furnace wall maintenance.

[0032] Refer to attached Figure 1-3 As shown, the specific structure is as follows:

[0033] 5.1 Compressed air device:

[0034] Such as image 3 As shown, a set of ...

Abstract

The invention provides a coke oven wall graphite cleaning method and a cleaning device. The method comprises the following steps: 1. injecting compressed gas carrying quartz sand into a carbonizationoven wall graphite; and 2, when injecting, embedding the quartz sand carried by the compressed gas into the gap of the furnace wall of the carbonization oven at the same time to finish repairing the gap of the furnace wall, wherein a spray gun entering the furnace is cooled.

Description

technical field [0001] The invention relates to a cleaning method and a cleaning device for graphite in the furnace wall of a coke oven carbonization chamber in the coking process. Background technique [0002] In coking production, the coal material in the carbonization chamber is received by the coal loading car from the coal tower, and then driven to the position of the carbonization chamber where coal needs to be charged, and the subsequent coal charging operation is carried out by the screw feeder. Coal is subjected to high-temperature dry distillation in the carbonization chamber. Over time, graphite will grow and adhere to the furnace wall of the carbonization chamber. Leakage, deformation and other consequences have a great impact on coking production. [0003] In the prior art, the cleaning of graphite on the furnace wall of the carbonization chamber adopts the original manual cleaning method, that is, after discovering that the furnace wall has accumulated graphit...
