Detailed Description
The present invention will be further described with reference to the accompanying drawings.
A bag filter in a net gas blowback box, as shown in figure 1, comprises a support 2, an ash bucket 3 and a bag chamber 8, wherein the bag chamber 8 is arranged on the support 2, the ash bucket 3 is arranged below the bag chamber 8, and a blowback port 81 is arranged on the surface of the bag chamber 8 opposite to the ash bucket 3; the bag chamber 8 is respectively provided with a waste gas inlet 7 and a purified gas outlet 13, the bag chamber 8 is internally provided with a filter bag 6, the filter bag 6 is inversely suspended in the bag chamber 8 through a filter bag suspender 9, as shown in figure 2, the lower opening of the filter bag 6 is sleeved on a bag opening ring 14 and is tightened and fixed with the card 4 through an anchor ear 5; the filter bag suspender (9) is fixed in the bag chamber (8) through a lifting valve (11); the purified air outlet 13 is connected with the back-blowing air port 81 through a ventilation pipeline, and the ventilation pipeline is provided with a fan 12 and a back-blowing valve 10.
The device also comprises a pressure sensor and a micro differential pressure controller; the pressure sensor is arranged in the filter bag 6, the micro differential pressure controller is arranged on the support 2, and the micro differential pressure controller is respectively connected with the pressure sensor, the lift valve 11, the fan 12 and the back blow valve 10.
The number of the ash buckets 3 is two, and the ash buckets 3 are provided with ash discharge valves 1.
