Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in figure 1, the spraying dust suppression device on the top of the coke oven mainly comprises a compressed air pipeline 1, a production water pipeline 2 and nine sets of spray head devices 3 with atomization effect, wherein the nine sets of spray head devices 3 are divided into two rows and are symmetrically arranged above the top 4 of the coke oven. As shown in fig. 2, a mixer 5 is provided in the head unit 3, and the compressed air pipe 1 is connected to the middle of the mixer 5 of the head unit 3 through nine first branch pipes 6; the production water pipeline 2 is connected with the top of the mixer 5 of the spray head device 3 through nine second branch pipelines 7, each first branch pipeline 6 is provided with a compressed air regulating valve 8, and each second branch pipeline 7 is provided with a production water pipeline regulating valve 9; the bottom of the nozzle device 3 is provided with an access opening 10. Clean water and compressed air in the production water pipeline 2 enter the spray head device 3 through the regulating device and the pipeline, and form mist by the built-in mixer 5 to be sprayed out through the spray outlet 11 (as shown in figure 3), so that the effects of reducing temperature and suppressing dust on the top of the coke oven are achieved.
