Dust Remover With Thickness-Controllable Sorted Accumulation Shelf Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional outer-filer type bag or filter cartridge dust removers suffer from incomplete cleaning, reduced filtration accuracy and efficiency due to the 'online pulse-jet deashing' process, which results in a discontinuous, unsorted, and uncontrollable dust accumulation shelf layer.
Innovation Solution
A dust remover with a thickness-controllable, sorted, and continuous super accumulation shelf layer is achieved by implementing an off-line pulse-jet deashing method using a high-pressure gas pulse-jet deashing device, sealable cinder valve, and controlled valve operations to create a static space for gravity sorting of dust particles, forming a continuous and sorted super accumulation shelf layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If online pulse-jet deashing is performed to maintain filtration resistance, then the dust accumulation shelf layer is broken and resistance is reduced, but the accumulation shelf layer becomes discontinuous and unsorted, reducing filtration accuracy
Solution Approach 1:
The patent performs pulse-jet deashing in advance before the accumulation shelf layer becomes too thick, rather than waiting for resistance to reach critical levels. This preliminary action prevents the formation of a thick, discontinuous dust layer while maintaining continuous filtration, thus preserving both resistance control and filtration accuracy
Solution Approach 2:
The patent maintains continuous operation of the dust remover without stopping for deashing cycles. By performing frequent, short-duration pulse-jet deashing operations, the accumulation shelf layer remains continuous and sorted, eliminating the discontinuities that occur with traditional periodic deashing while maintaining reliable resistance control
2Reliability
If high-frequency pulse-jet deashing is performed to control resistance, then resistance value is maintained, but filtration accuracy and efficiency are severely affected due to micropore expansion
Solution Approach 1:
The patent uses periodic pulse-jet deashing with optimized timing and duration. Instead of continuous high-frequency deashing that causes micropore expansion, short periodic pulses are applied just sufficient to maintain resistance control without excessive frequency, thus preserving filtration accuracy while maintaining resistance reliability
Solution Approach 2:
The patent changes the parameters of pulse-jet deashing (duration, frequency, pressure) to optimize the balance between resistance control and filtration accuracy. By adjusting these parameters, the system maintains reliable resistance values while minimizing the negative impact on filtration performance
3Productivity
If pulse-jet deashing breaks the accumulation shelf layer repeatedly, then resistance is reduced and dedusting continues, but the dust layer cannot be cleaned completely and dust re-attaches to the filter surface
Solution Approach 1:
The patent maintains continuous dedusting operation with frequent, light pulse-jet interventions rather than complete breakdown cycles. This continuous approach prevents dust from re-attaching to the filter surface by maintaining a thin, sorted accumulation layer, achieving both productivity and cleaning completeness
Solution Approach 2:
The patent performs pulse-jet deashing before the dust layer becomes thick and difficult to remove. This preliminary action prevents complete accumulation while maintaining continuous operation, ensuring dust is removed before it can re-attach strongly to the filter surface

AI summary
The present invention belongs to the field of environmentally dust removing equipment apparatus, and specifically relates to a dust remover with a thickness-controllable, sorted and continuous accumulation shelf layer, and an operation method thereof. The dust remover comprises a gas purification chamber, a dust filtration chamber, an ash bucket and a high-pressure gas pulse-jet deashing device. A valve is provided on the exhaust gas inlet pipe and/or the purified gas outlet pipe. The distance L from the inlet pipe valve to the exhaust gas inlet of the filtration chamber is 0-1.0 m or 1.0-10 m. Two or more dust removers are communicated with the dust source separately or in parallel, so as to form a group of dust removers. When the dust remover performs off-line deashing, the valve on the exhaust gas inlet pipe and/or the purified gas outlet pipe is closed, and the pulse-jet deashing device is started up to perform jet deashing. After it completes the jet deashing and waits for a time ΔT, the valve on the exhaust gas inlet pipe and/or the purified gas outlet pipe is opened to continuously perform the dedusting. The present invention provides a new dedusting mode with the “super accumulation shelf layer,” which significantly improves the filtration accuracy and the dedusting efficiency of the dust remover.
