Description

Technical Field

[0001] This invention relates to the field of environmental engineering technology, and in particular to a comprehensive intelligent environmental protection system applicable to gantry-type blending stacker-reclaimers. Background Technology

[0002] Currently, the gantry stacker-reclaimer (hereinafter referred to as "gantry crane"), a typical bulk material conveying equipment in coal storage yards, generates a significant amount of dust during operation. Based on the need to protect the environment and reduce and avoid health hazards to operators, eliminating the dust generated by gantry crane operation has become an essential supporting equipment.

[0003] Therefore, developing and reserving intelligent and environmentally friendly dust suppression system technologies suitable for gantry stacker-reclaimers is of significant research value. Currently, there are no mature environmentally friendly dust suppression products for gantry stackers in China. Existing dust suppression products—water spraying systems—are limited in function, simple in structure, lack effective insulation and intelligent control, and are ineffective in dust suppression. Furthermore, they are severely affected by seasonal factors. Therefore, based on the principles of environmental protection and reducing and avoiding health hazards to operators, developing a comprehensive intelligent and environmentally friendly dust suppression system suitable for gantry stackers to eliminate dust generated during operation and meet environmental emission requirements is a problem urgently needing to be solved by those skilled in the art. Summary of the Invention
