Background
The flue gas generated in the converter blowing process contains toxic gases such as sulfur dioxide and the like and dust such as iron, lead and the like, and has the main characteristics of high temperature and high dust concentration. The dust is dedusted by a converter settling chamber and then is conveyed to an electric dust collection system through a flue gas pipeline. In the flue gas conveying pipeline, in order to control the trend of flue gas and cut off the flue gas, a valve is often installed, and a butterfly valve has the characteristic of good sealing property, so that the butterfly valve is widely applied to the flue gas pipeline.
The dust in the smoke dust is easy to deposit and bond on the valve core of the butterfly valve, so that the valve core is blocked, and the valve cannot be normally opened and closed, thereby influencing the normal production of the converter and even causing safety and environmental protection accidents. When the furnace is shut down for maintenance, the occurrence of poisoning accidents of maintenance personnel in the furnace caused by the backflow of the smoke due to the fact that the smoke butterfly valve is not closed tightly often occurs. The dust on the smoke butterfly valve, especially the valve core, can not be cleaned in production, and therefore the normal operation of production or maintenance operation is influenced.
Disclosure of Invention
In order to overcome the problem that exists among the background art, the utility model provides a prevent to smelt with device of flue gas valve deposition can clear up the case of butterfly valve safely, effectively, has effectively guaranteed the normal clear of production or maintenance operation.
The description of the front and rear directions in this specification is based on the direction of the flue gas in the flue gas duct during normal production.
In order to achieve the above purpose, the utility model is realized by the following technical scheme:
the device for preventing ash accumulation of the smoke valve for smelting comprises a butterfly valve, an ash discharge port, a blowing air pipe and a reducer pipe; the reducing pipe is arranged on the flue gas pipeline, and the butterfly valve is connected to the reducing pipe section through a flange; the purging air pipe penetrates through the flue gas pipeline wall on the rear side of the butterfly valve, and the outlet of the purging air pipe is opposite to the valve core position of the butterfly valve; the ash discharge opening is arranged at the bottom of the reducer pipe on the front side of the butterfly valve.
Preferably, the blowpipe is provided with a valve which vertically penetrates through the wall of the flue gas pipeline, and the outlet section and the vertical section form an included angle of 60-120 degrees.
Preferably, the ash discharge port is arranged at the joint of the reducer pipe and the flue gas pipeline, and the ash discharge port is provided with a valve.
Preferably, the distance between the outlet of the purge air pipe and the butterfly valve is about 100-1000mm.
The utility model has the advantages that:
according to the utility model, the blowing pipe is arranged at the rear side of the flue gas pipeline according to the condition that smoke dust in the flue gas is easy to adhere to the butterfly valve core and causes the butterfly valve to be difficult to open or close, and the dust on the butterfly valve core is swept and cleaned by using compressed air, so that the butterfly valve does not need to be disassembled, and the flue gas cannot be leaked during sweeping, and the structure is simple, safe and effective; meanwhile, in order to prevent the smoke pipeline on the front side of the butterfly valve from being blocked due to smoke accumulation, the ash discharge port is arranged, so that the blocking dust can be effectively discharged through the ash discharge port when the smoke pipeline on the front side of the butterfly valve is blocked, the blowing effectiveness is further ensured, the ash discharge port is arranged at the joint of the reducer pipe and the smoke pipeline, a slope is formed on the right side of the ash discharge port, and the dust discharge is facilitated; the design of the blowing angle of the blowing air pipe and the distance between the blowing air pipe and the butterfly valve can effectively ensure the blowing effect; the blowpipe is arranged on the rear side of the flue gas pipeline and is opposite to the forming direction of accumulated dust of the valve core of the butterfly valve, so that effective purging is facilitated.

in the figure, 1-butterfly valve, 2-ash hole, 3-blowing air pipe, 4-reducer pipe, 5-flue gas pipeline, 6-valve and 7-flange.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in figure 1, the device for preventing ash deposition of the smoke valve for smelting comprises a butterfly valve 1, an ash discharge port 2, a purging air pipe 3 and a reducer pipe 4; reducer pipe 4 is connected on flue gas pipeline 5, and the centre is the tubule, and pipe diameter and butterfly valve 1 phase-match, and the both ends pipe diameter of reducer pipe 4 is unanimous with flue gas pipeline 5 pipe diameter, reducer pipe 4 and flue gas pipeline welding. The setting of reducing pipeline, the pipeline slope of formation can effectively avoid the smoke and dust to pile up in butterfly valve case both sides to cause the emergence of the not tight condition of butterfly valve shut, the inclined plane that the reducing pipe produced is favorable to the use of ash discharging port 2 in addition, the deposition clearance of being convenient for. The butterfly valve 1 is connected with the thin pipe section of the reducer pipe 4 through a flange 7; the blowing air pipe 3 vertically penetrates through the pipe wall of the flue gas pipeline 5 on the rear side of the butterfly valve 1, the outlet section and the vertical section form included angles of 60-120 degrees, the outlet is over against the valve core position of the butterfly valve 1, the distance between the outlet and the butterfly valve 1 is 100-plus-1000 mm, the distance can prevent the blowing pipe 3 from influencing the normal opening and closing of the butterfly valve 1, the blowing effect is ensured, and in the using process, the blowing air pipe can be adjusted according to the size of the butterfly valve 1 and the blowing air pressure.
