[0002] Today, as domestic environmental awareness and requirements are increasing, circular material yards and their equipment, circular stackers and reclaimers, have been widely used in material storage and transportation systems in the power, building materials, chemical, mining, docks, coal, grain and other industries with their advanced technology, high level of program control, outstanding environmental performance, and less land occupation. Circular stackers and reclaimers are also receiving more and more widespread attention.

[0003] As one of its main structures, the dry fog dust removal system is arranged on the circular stacker-reclaimer. By arranging it at the dust generating point, dust reduction and environmental protection are achieved. However, due to the working mode of the circular stacker-reclaimer, a large amount of dust is often generated at the outlet of the coal hopper during the stacking operation. However, due to the high dust concentration at this position, spray points need to be arranged around the material flow.

[0004] Therefore, those skilled in the art provide an annular spray device for dust removal of a circular stacker-reclaimer to solve the problems raised in the above background technology. Utility Model Content

[0005] The utility model provides an annular spray device for dust removal of a circular stacker and reclaimer, which solves the dust reduction problem of the circular stacker and reclaimer and realizes 360° all-round spray dust reduction on the material flow by arranging an annular spray device below the outlet of the stacking coal hopper.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model discloses an annular spray device for dust removal of a circular stacker and reclaimer, comprising:

[0008] An annular water pipe, the top end of which is hoisted below the outlet of the stockpile coal hopper through a lifting lug;

[0009] A water inlet interface, which is arranged on one side of the annular water pipe;

[0010] An air inlet interface, which is arranged on the other side of the annular water pipe;

[0011] A plurality of two-fluid nozzles are evenly arranged on the bottom surface of the annular water pipe.

[0012] Furthermore, the water inlet interface is communicated with the inner cavity of the annular water pipe.

[0013] Furthermore, the water inlet end of the two-fluid nozzle is connected to the inner cavity of the annular water pipe.

[0014] Furthermore, an annular air pipe is provided in the inner cavity of the annular water pipe, and the annular air pipe is communicated with the air inlet interface.

[0015] Furthermore, the air inlet end of the two-fluid nozzle is connected to the annular air pipe.

[0016] In the above technical scheme, the utility model provides an annular spray device for dust removal of a circular stacker and reclaimer, which has the following beneficial effects: multiple two-fluid nozzles spray annular sprays to reduce dust in all directions below the outlet of the stacking coal hopper, that is, to achieve 360° all-round spray dust reduction on the material flow, with good dust reduction effect.
