Description

Technical Field

[0001] The invention relates to the field of coking industrial equipment, and in particular to an automatic coke cleaning device and a cleaning method for a coke flow plate. Background Art

[0002] The coke pusher and coke guide car remove the furnace door. When the door remover removes the furnace door and the furnace door moves back and leaves the furnace mouth, the coke at the top of the carbonization chamber near the furnace door forms cracks after coking, and the coke adhesion decreases. Under the action of gravity, stepped coke is formed; in the middle and lower part that fits the furnace door, the coal powder is not completely coked due to heating restrictions, forming a semi-coked state, and is separated from the furnace door when the furnace door moves back. The fallen coke, coal powder, tar, etc. fall on the coke-draining plate.

[0003] At present, the collapsed coke (red coke), coal powder and tar are shoveled by the furnace workers into the coke receiving port of the coke pusher and coke guide car. The scraper in front of the furnace has a water tank, and the scraper conveys the extinguished coke, coal powder, etc. to the coke storage bucket for recovery. The existing operation mainly has the following problems: 1. The working environment is harsh. The temperature at the furnace mouth of the carbonization chamber is about 1000℃. The furnace workers use iron shovels to scrape the scattered coke (red coke) and coal powder into the water trough in front of the furnace. When the red coke meets water, it will emit a large amount of water vapor, which affects the vision of the furnace workers and poses safety risks in their work. The heat radiation in the carbonization chamber also affects the health of the furnace workers.

[0004] 2. The operation affects the time of coke oven output. A group of coke ovens can produce 130 coke ovens in one day (24 hours). The operation time of cleaning the coke plate of each oven is 2 minutes. The time affected every day is 260 minutes.

[0005] 3. The cleaning work of the furnace workers needs to be carried out near the front of the furnace, and there is a lot of interaction with the coke oven vehicles, which can easily cause mechanical injury accidents. Summary of the invention

[0033] In this embodiment, by determining the two working positions of the focus guide frame 200 (the operating position with a distance X, and the control position with a distance Y), the linkage between the focus guide frame 200 and the purge mechanism 100 can be improved, thereby improving the degree of automation.

[0034] In some embodiments, the purging mechanism 100 includes a compressed air source 110, a nozzle 120 and a solenoid valve 130.

In the process of high-pressure gas flowing in the entire jet hole 121, the flow rate of high-pressure gas can be accelerated first, and then concentrated and diffused, so that it can be fully dispersed on the surface of the entire coking plate, and each area of ​​the coking plate can be effectively cleaned. Furthermore, from the acceleration of the contraction section 1211 to the low-pressure state of the throat 1212, and then to the deceleration and static pressure recovery of the diffusion section 1213, the entire flow process has a certain directionality and stability, which plays a role in guiding the high-pressure airflow (along the Figure 4arrows) to avoid non-directional dispersion of high-pressure airflow.
