Flue gas guide device for desulfurizing column

Abstract

The invention relates to the technical field of a desulfurization column and further discloses a flue gas guiding device for the desulfurizing column. The flue gas guiding device comprises a regulating tube, wherein an air inlet pipe is fixedly connected above the adjusting pipe; an air outlet pipe is fixedly connected below the adjusting pipe; the output shaft penetrates through the adjusting pipe and is arranged in the adjusting pipe; a first bevel gear is arranged on the output shaft; a second bevel gear is arranged in the cylinder body, wherein the second bevel gear is arranged on a screwrod, a screw plate is connected to the screw rod, multiple sets of cones are arranged above the screw plate, springs are connected between the cones, and an extrusion sleeve is arranged on the peripheries of the cones; a rope body is connected to the extrusion sleeve, wherein the other end of the rope body is connected with a reel; and a cavity is formed between the multiple sets of cones. According to the flue gas guide device for the desulfurizing column, the passing area of flue gas can be changed through vertical movement of the cone, the flue gas flowing volume in unit time can be changedby changing the size of the cavity, and the flue gas guide device has the advantage that the air volume adjusting mode is diversified.

Description

technical field [0001] The invention relates to the technical field of desulfurization towers, in particular to a flue gas guiding device for desulfurization towers. Background technique [0002] Flue gas desulfurization refers to the process of removing sulfur oxides from flue gas or other industrial waste gases. At present, the commonly used flue gas desulfurization methods can be roughly divided into three categories according to their processes: wet disposal process, wet recovery process and dry process. craft. In the desulfurization process of flue gas, the desulfurization tower can often play an important role. The desulfurization tower is a tower equipment for desulfurization of industrial waste gas. The technology of the existing desulfurization tower is becoming more and more mature. Compared with the previous There are also more and more varieties, and most desulfurization towers are equipped with flue gas guiding devices. [0003] The flue gas guiding device can...
