Bubble tube for desulfurization tower with anti-backflow and split flow

Abstract

A bubbling tube for a desulfurization tower with anti-backflow and split flow, relates to the technical field of renewable clean energy, including a bubbling tube, the inner side of the top of the bubbling tube is fixedly connected with a sealing ring, and the inner side of the bubbling tube is close to the sealing ring The bottom is fixedly connected with a fixed block. The anti-backflow and split flow desulfurization tower uses a bubble tube through the cooperation of the floating block and the movable valve. When the exhaust gas to be reacted is passed into the bubble tube, the movable valve is opened under the blowing of the exhaust gas and the gravity of the movable tube. , when the desulfurization tower stops working, the temperature in the bubble tube will drop, and the limestone solution will easily flow back into the bubble tube. The floating block at the bottom of the movable tube has a lower density than the limestone solution, so the movable tube will be under the buoyancy of the floating block. Float up and down, and the movable pipe will close the movable valve through the hinged rod, preventing the limestone solution from entering the middle layer of the desulfurization tower from the bubbling pipe, avoiding the reduction of desulfurization caused by backflow, and ensuring the desulfurization effect.

Description

technical field [0001] The invention relates to the technical field of renewable clean energy, in particular to a bubbling tube for a desulfurization tower with anti-backflow and split flow. Background technique [0002] Air pollution has become a global problem. Air pollution is mainly caused by sulfides, nitrides, and carbides in industrial production and daily life. The production of these harmful substances accelerates air pollution and causes serious damage to the atmosphere. In order to control To further pollute the atmosphere, the government ordered to strictly control the emission indicators of large-scale industrial production waste gas. The current factory uses a series of desulfurization and denitrification equipment to treat the sulfide in the waste gas. [0003] The desulfurization device in the industry is a desulfurization tower. The current working principle of the desulfurization tower is to pass the exhaust gas into the middle of the desulfurization tower,...

AI Technical Summary

Problems solved by technology

[0005] 1. When the exhaust gas passes through the bubbling tube, the air flow is relatively turbulent and the distribution is uneven, which makes it difficult to completely react the remaining 42% of sulfur oxide when the exhaust gas is in contact with the limestone solution, resulting in an excessively high sulfur content in the exhaust gas;

[0006] 2. The exhaust gas itself has temperature. Since the bottom of the bubbling tube is immersed in the limestone solution, when the desulfurization tower stops working and the temperature in the tube drops, the solution will easily flow back, causing the bubbling tube to be blocked by the limestone solution, which will affect the next time. use
