A flue gas guiding device for desulfurization tower

Abstract

The invention relates to the technical field of desulfurization towers, and discloses a flue gas guiding device for desulfurization towers, which includes a regulating pipe, an air inlet pipe is fixedly connected above the regulating pipe, an air outlet pipe is fixedly connected below the regulating pipe, and an air outlet pipe is fixedly connected below the regulating pipe. The shaft passes through the adjusting tube and is set inside the adjusting tube, the output shaft is provided with a first bevel gear, the inside of the cylinder is provided with a second bevel gear, the second bevel gear is set on a screw, and a screw plate is connected to the screw. There are multiple sets of cones above the screw plate, springs are connected between the cones, extrusion sleeves are arranged on the periphery of the cones, a rope is connected to the extrusion sleeve, and the other end of the rope is connected to the winding wheel. Cavities are formed between the sets of cones. The flue gas guiding device for the desulfurization tower can change the passing area of ​​the flue gas through the up and down movement of the cone, and can change the flow volume of the flue gas per unit time by changing the size of the cavity, and has a variety of ways to adjust the air volume. advantage.

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...
