Coke Oven Scoop Suction for Emissions Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coke oven operating devices fail to effectively capture and prevent pollutant emissions, including vapors, gases, and smoke, from the coke shovel area, which are not picked up by suction devices on coke squeezing and transfer machines, leading to environmental pollution.
Innovation Solution
The integration of suction devices on the coke shovel, preferably as vortex hoods with multiple suction points, positioned on the longitudinal sides and upper edges of the coke blade, designed to capture emissions before they escape into the environment, ensuring complete collection and efficient air flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If suction devices are added to the coke shovel, then emissions capture effectiveness is improved, but device complexity increases
Solution Approach 1:
The suction device is integrated directly onto the coke shovel structure, merging the emissions capture function with the existing coke collection and transfer mechanism. This combination allows the suction openings to be positioned exactly where emissions are generated, maximizing capture effectiveness while avoiding the need for separate, standalone suction equipment that would increase overall system complexity.
Solution Approach 2:
The coke shovel is designed to perform multiple functions: collecting sloppy coke, transferring it to the collection container, and simultaneously capturing emissions through integrated suction openings. This multi-functionality eliminates the need for separate dedicated emissions control equipment, thereby improving capture effectiveness without proportionally increasing device complexity.
2Object-affected harmful factors
If suction openings are positioned at the upper edge of the coke blade, then emissions capture completeness is improved, but device complexity increases
Solution Approach 1:
Suction openings are strategically positioned at the upper edge of the coke blade where emissions naturally rise and accumulate. This localized placement targets the specific region where emissions are most concentrated, ensuring complete capture without requiring suction openings throughout the entire structure, thus maintaining simplicity while achieving completeness.
3Object-affected harmful factors
If suction device extends over partial area of longitudinal side, then emissions capture effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The suction device extends over only the necessary portion of the longitudinal side of the coke blade - specifically the area where emissions are generated during coke collection and transfer. This partial coverage approach provides sufficient emissions capture effectiveness without the excessive cost of covering the entire surface area, achieving an optimal balance between performance and manufacturing cost.
