Preferably, the multi-stage connecting pipeline includes a curved pipeline 171, a vertical pipeline 172 and an S-shaped pipeline 173 connected in sequence, the S-shaped pipeline 173 is communicated with the first dust removing box 101, and the curved pipeline 171 is communicated with the second dust removing box 111. The second spray dust collector 13 is arranged on the vertical pipeline 172 and the S-shaped pipeline 173, the S-shaped pipeline 173 can reduce the flow speed of the air flow, and better dust collection effect can be achieved after the second spray dust collector 13 is matched. Alternatively, the lengths of the curved pipeline 171 and the vertical pipeline 172 are in the range of 5m to 30m, so that the length of the middle pipeline 17 can be increased, friction noise generated by contact between the air flow and the inner wall of the middle pipeline 17 can be effectively reduced, larger solid particles can be precipitated in the longer middle pipeline 17, and the water flow generated by the second spray dust removing device 13 flows into the first dust removing box 101 with the precipitated solid particles. In addition, the second water bath dust collector 11 can be introduced into the roof to facilitate the discharge of clean air. Further, the included angle between the S-shaped pipeline 173 and the horizontal plane is 30-90 degrees. This can facilitate the flow of sewage into the first dust box 101.
As an embodiment, the polishing and dedusting system further includes at least two temperature sensors 18, where the at least two temperature sensors 18 are disposed in the air inlet pipe 15 and the intermediate pipe 17, and the temperature sensors 18 can monitor the temperature of the air flow in the air inlet pipe 15 and the intermediate pipe 17. If the detected temperature of the temperature sensor 18 is greater than the preset temperature, the first spray dust collector 12 and the second spray dust collector 13 perform cooling operation. When the temperature in the pipeline is too high, the temperature sensor 18 can send out an alarm, and the first spray dust removing device 12 and the second spray dust removing device 13 are started to cool. Therefore, the temperature of the air flow in each pipeline can be monitored, and the spraying cooling can be performed once abnormality is found, so that the fire hazard is reduced.
Further, the polishing dust removal system further comprises a fireproof spraying device 19, and the fireproof spraying device 19 is arranged in the middle pipeline; the fire protection shower 19 serves to cool the air flow in the intermediate line 17 and to clean the intermediate line 17. When the temperature in the official way is too high, the fireproof spraying device 19 can be started to cool the pipeline. Of course, besides the fireproof function, the fireproof spraying device 19 can be started at regular time every day to spray and clean the intermediate pipeline 17, so that the intermediate pipeline 17 is ensured to be clean. Preferably, the fire protection sprinkler 19 uses a sprinkler head to spray water, the source of which is also clean water in the multi-stage sediment filter tank 103.
Still further, the air inlet duct 15 has a convex portion 151 protruding outward, and the sensor is located in the convex portion 151. The convex portion 151 is a wind-shielding region, so that the air flow can be prevented from impacting the temperature sensor 18, the impact force received by the temperature sensor 18 can be reduced, and the usability of the temperature sensor 18 can be improved.
