Description

Technical Field

[0001] The invention relates to the technical field of industrial flue gas treatment, in particular to a dust reaction tower with a combined dust cleaning system. Background Art

[0002] With the increasingly stringent requirements for ammonia oxide emissions from cement production lines, the use of selective catalytic reduction for denitrification is the main research direction for denitrification in cement production lines. Since the flue gas from cement kilns contains dust, the dust will be deposited on the surface of the catalyst when the flue gas passes through the catalyst bed, blocking the catalyst pores and reducing the denitrification efficiency. The dust concentration inside the reaction tower is about 50 to 100 times higher than that of a general reaction tower. The slurry or solid alkaline chemicals injected during the reaction in the tower can all adhere to the surface of the particles, expanding the contact area with various acidic pollutants such as sulfur oxides, hydrogen fluoride, and hydrogen chloride in the reaction tower and removing them.

[0003] Authorization announcement number CN 218901422 U discloses a reaction tower with a combined dust cleaning system. This patented technology uses a rake soot blower with strong dust cleaning strength. Within its walking range, it can effectively clean sticky dust. The sonic soot blower generates sound waves in the entire reaction layer area, repeatedly pulling and pressing the accumulated dust, thereby loosening the dust and falling off. It can effectively clean the accumulated dust in corners and other areas that are difficult for the rake soot blower to cover. The combined dust cleaning mechanism can not only fully handle sticky dust, but also reduce the consumption of compressed air in the entire cleaning system; however, the disadvantage of using a rake soot blower in this scheme is that it will damage the catalyst, affecting the service life of the catalyst, and especially for sticky ash, it cannot be effectively handled. The biggest shortcoming of the rake soot blower is that the cleaning effect of sticky ash is poor. Therefore, a dust reaction tower with a combined dust cleaning system is needed to improve the above problems. Summary of the invention

[0004] In order to solve the disadvantages of the existing scheme of using rake soot blowers, which cause damage to the catalyst and affect the service life of the catalyst, and especially cannot effectively treat the sticky ash, the biggest shortcoming of the rake soot blower is the poor cleaning effect of the sticky ash.
