Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression in coal yards, and more specifically to an improved coal yard spray dust suppression device. Background Art

[0002] A coal yard is a place where coal is piled up, usually an auxiliary facility of a coal-fired power plant or steel plant. With the continuous improvement of my country's coal production capacity, the increasingly stringent national environmental protection policies and the increasing awareness of environmental protection, the open-air coal storage method commonly used by coal production enterprises has been no longer in line with the requirements. It is necessary to adopt a fully enclosed coal storage yard that meets the actual needs of the enterprise to ensure the good economic, environmental and social benefits of the enterprise. At present, when vehicles transport coal to the coal unloading point of the coal yard for unloading operations, a large amount of coal dust and dust will be generated, which will endanger the health of workers. In order to effectively suppress the spread of coal dust from the source, a spray pile is usually installed at the coal unloading point for spraying and dust suppression.
