Description

TECHNICAL FIELD

[0001] The utility model relates to lime kiln cleaning equipment technical field, more exactly relates to a high pressure purging device for lime kiln passage cleaning. BACKGROUND

[0002] As an important equipment for producing lime, the lime kiln inevitably has problems of material scaling and dust accumulation in its internal passage during long-time operation. These scaling and dust accumulation will gradually pile up, resulting in a decrease in the effective flow area of the lime kiln passage and seriously affecting the normal operation efficiency of the lime kiln. On the one hand, a large amount of dust and high-temperature gas will be generated during the calcination of limestone in the lime kiln. These dusts will flow with the airflow in the passage, some of which will adhere to the passage wall, especially in the curved passage, variable-diameter passage and areas with low airflow speed, which are more prone to dust accumulation. With the passage of time, the dust accumulation will become thicker, increasing the airflow resistance and causing poor ventilation, which will further affect the combustion effect in the lime kiln and the calcination quality of limestone. On the other hand, due to a series of physical and chemical changes of limestone during calcination, part of the material may adhere to the passage wall to form hard scaling. These scaling will not only further reduce the flow area of the passage, but also cause corrosion and wear of the passage wall, shortening the service life of the lime kiln.

[0003] Currently, the cleaning of the lime kiln passage is usually performed manually. Manual cleaning requires the operator to enter the interior of the lime kiln, which not only has high labor intensity, poor working environment and certain safety risks, but also has low cleaning efficiency.
