Dedusting wind pressure balancing device

The invention discloses a dust removal wind pressure balancing device. The device comprises a fan, one side of the fan is connected with a chimney matched with a fan opening in specification and size,the chimney is connected with a bag-type dust remover through an outlet connecting pipeline, the side, opposite to the outlet connecting pipeline, of the bag-type dust remover is connected with a fire-retardant box cooler through a connecting pipeline, and one end of the fire-retardant box cooler is connected with a dust removal main pipe of coke oven equipment through a pipeline and elbow structure. Compared with like devices in the prior art, the device of the invention has the following advantages: a residual pressure valve is specially arranged at the pipeline opening of the fan, and whenthe suction force exceeds a fixed value, the residual pressure valve is automatically opened to supplement air to adjust the pressure so as to guarantee safe operation of the pipeline; the device isintegrally closed tightly,
