Power plant desulphurization device suitable for rainy days and capable of accelerating gas exhaust

Abstract

The invention discloses a power plant desulphurization device suitable for rainy days and capable of accelerating gas exhaust. The power plant desulphurization device structurally comprises a desulphurization tower, a shielding device and an accelerating device. The shielding device is mounted on the top of the desulphurization tower, and the accelerating device is arranged below the shielding device and mounted on the desulphurization tower. The shielding device is composed of a vertical rod, a supporting rod, a lower supporting disc, fixing rods, a water channel, an upper supporting disc, umbrella blocks, fulcrum rods, woven fabric and a water pipe, the vertical pipe is fixed to the middle of the desulphurization tower through the supporting rod, the lower supporting disc and the upper supporting disc are arranged at the upper end and the lower end of the supporting rod respectively, round rails are arranged on the side face of the lower supporting disc and the side face of the uppersupporting disc respectively, and sliding blocks are arranged at the two ends of the fulcrum rods respectively. The power plant desulphurization device has the advantages that rainwater is preventedfrom falling into the desulphurization tower, gas backflow is avoided, the gas exhaust speed is increased, the use cost is reduced, and it is guaranteed that the desulphurization device normally workson the rainy days.

Description

technical field [0001] The invention relates to the field of power plant desulfurization equipment, in particular to a power plant desulfurization device suitable for accelerating gas output in rainy days. Background technique [0002] The gas discharged from the power plant contains SO2, which will cause harm to the atmosphere and the human body, and must be desulfurized. [0003] At present, the discharge port of the desulfurization device in the power plant is generally chimney-shaped. When it rains, the rain falls into the chimney, which will cause the discharged gas to flow back. The internal gas accumulation prevents the gas from being discharged in time, which is easy to affect the desulfurization. Rainy days increase the air humidity, the greater the humidity, the more difficult it is for the gas to be discharged, which affects the desulfurization treatment speed. Contents of the invention [0004] The main purpose of the present invention is to overcome the defic...
