Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collection devices face difficulties in efficiently removing dust from filters while the blower is running due to pressure differences, making it challenging to perform dedusting effectively.
Innovation Solution
A dust collection device that introduces a higher atmospheric pressure to the air passage downstream of the filter during operation, reducing the pressure difference and allowing for easy dust removal without stopping the blower.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the blower is running to maintain dust collection operation, then dust collection productivity is improved, but the pressure difference across the filter increases making dust removal difficult
Solution Approach 1:
A pressure introduction device is introduced as an intermediary component to supply high-pressure air to the downstream side of the filter. This mediator overcomes the adverse pressure difference created by the running blower, enabling dust removal to proceed effectively without stopping the dust collection operation.
Solution Approach 2:
The pressure parameter in the downstream air passage is actively changed by introducing high-pressure air from the pressure introduction device. This parameter change counteracts the pressure difference that prevents dust removal, allowing the dust removal device to function effectively while the blower continues running.
2Ease of operation
If the blower is stopped to reduce pressure difference for dust removal, then dust removal effectiveness is improved, but dust collection productivity decreases
Solution Approach 1:
The pressure introduction device serves as a mediator that enables dust removal operations to proceed without requiring the blower to stop. By supplying high-pressure air to balance the pressure difference, it decouples the dust removal process from the dust collection process, allowing both to operate simultaneously.
Solution Approach 2:
High-pressure air is introduced in advance to the downstream side before dust removal begins, preparing the pressure conditions necessary for effective dust removal. This preliminary pressure equalization allows the dust removal device to operate immediately without requiring blower shutdown.
3Ease of operation
If high pressure is introduced to the downstream air passage, then the pressure difference across the filter is reduced improving dust removal, but the system complexity increases
Solution Approach 1:
The pressure introduction device is designed to integrate with the existing dust collection system architecture, serving multiple functions: it provides high-pressure air for dust removal, maintains system pressure balance, and operates within the existing air passage structure. This multi-functionality reduces the need for entirely separate systems.
Solution Approach 2:
The pressure introduction device utilizes the system's own air resources to generate the high-pressure flow needed for dust removal. By tapping into the existing air supply and using the system's operational air flow, it reduces dependency on external high-pressure sources and simplifies the overall system configuration.

AI summary
A dust collection device (1) for removing fine particles from an atmosphere is provided with a filter (3), a blower (11), a dust removal device (7), and a pressure introduction device (9). The filter (3) removes fine particles from an atmosphere drawn into a filter chamber (5A). The blower (11) draws the atmosphere into the filter chamber (5A) and generates an air flow through the filter (3). The dust removal device (7) removes fine particles adhering to the filter (3). The pressure introduction device operates during operation of the dust removal device (7) and introduces an atmospheric pressure higher than the atmospheric pressure inside an air passage to the air passage downstream from the filter (3).
