Energy-saving device of wet desulphurization spray tower

Abstract

The invention provides an energy-saving device of a wet desulphurization spray tower. The device is arranged on the tower wall of the wet desulphurization spray tower between an inlet of the wet desulphurization spray tower and a lowermost spray layer. The energy-saving device comprises a reinforcing plate fixed on the inner side of the tower wall, a bottom plate connected with the reinforcing plate, a side plate installed on the inner side of the bottom plate, pull rods, a sealing plate, vent pipes and flow guide plates; at least two pull rods are arranged between the side plate and the bottom plate; two ends of each pull rod are respectively connected with the inner wall of the side plate and the upper wall of the bottom plate; the inclined sealing plate is welded between the lower bottom surface of the bottom plate and the tower wall; at least two vent pipes are arranged on the tower wall below the bottom plate; the flow guide plates are arranged at two ends of the bottom plate; oneend of each flow guide plate is connected with the reinforcing plate, and a liquid discharge outlet is formed between the other end of each flow guide plate and the side plate. With the device adopted, the problem of accumulation of solids at the inlet of the tower can be effectively solved, a waterfall phenomenon can be avoided, flue gas resistance can be reduced, and energy conservation can berealized.

Description

【Technical field】 [0001] The invention relates to the technical field of wet desulfurization spray towers, in particular to an energy-saving device for wet desulfurization spray towers. 【Background technique】 [0002] At present, my country's thermal power, iron and steel, metallurgy, cement and other industries mainly use wet desulfurization spray towers to remove sulfur dioxide in flue gas. After the spray layer nozzle near the tower wall sprays the absorption liquid onto the inner wall of the desulfurization spray tower, the absorption liquid will flow down along the tower wall. When the absorption liquid flows to the flue gas inlet, it will flow down in a "waterfall" shape. [0003] On the one hand, when the absorption liquid flows to the flue gas inlet, it flows down in a "waterfall" shape. The "waterfall" absorption liquid will block the flue gas entering the spray tower, increase the resistance of the flue gas, and thus increase the energy consumption of the desulfu...

AI Technical Summary

Problems solved by technology

The "waterfall" absorbing liquid will block the flue gas entering the spray tower, increase the resistance of the flue gas, and thus increase the energy consumption of the desulfurization fan

On the other hand, the "waterfall" will lead to the accumulation of solids in the flue gas inlet flue, increasing the resistance of the flue gas, thereby increasing the energy consumption of the desulfurization fan

[0004] In order to overcome the above problems, the patent of China Authorized Notification No. CN 208260533 U discloses a wet desulfurization tower inlet device. Although the device reduces energy consumption to a certain extent, there are still some shortcomings, such as the structure is not simple enough There are many tie rods between the side plate of the groove and the tower wall, and there are many solder joints on the tower wall, and the anti-corrosion construction in the connection area between the tie rods and the tower wall is difficult, which increases the safety hazard of the tower wall and the maintenance cost; because the tower wall is round The arc-shaped structure, the slurry discharged from both sides of the slurry tank will directly impact the tower wall, increasing the risk of the tower wall being worn through; the bottom plate of the tank, the tower body and the inclined sealing plate form a closed structure, and the stress generated by the change of internal air pressure will The welding seam and the internal structure have adverse effects, and a wet desulfurization spray tower energy-saving device is proposed
