Horizontal type desulfurization reactor for industrial flue gas and flue gas treatment method

Abstract

The invention discloses a horizontal type desulfurization reactor for industrial flue gas, which comprises a horizontal tube body. A distributed orifice plate in the tube body divides the inner chamber of the tube body into two hollow chamber, i.e., an upper hollow chamber and a lower hollow chamber, wherein the upper hollow chamber is a doctor solution distributed chamber; the lower hollow chamber is a desulfurizing chamber; the top of the tube body is provided with an alkali liquor inlet which is used for inputting doctor solution to the doctor solution distributed chamber; one end of the tube body is provided with a flue gas inlet, and the other end of the tube body is provided with a flue gas outlet; and flue gas enters into the desulfurizing chamber from the flue gas inlet to be in contact with the alkali liquor in a square crossing manner, and thus the desulfurization is carried out. The horizontal type desulfurization reactor disclosed by the invention has a simple structure; in addition, gas is in contact with the liquor in the desulfurizing chamber a square crossing manner, the desulfurization effect is good, the flue gas and the alkali liquor are in non-counterflow motion, no guide plates exist in the moving direction of the flue gas in the desulfurizing chamber, the system resistance is little, the electric energy consumption is low, and the high-efficiency operation can be maintained for a long time.

Description

technical field [0001] The invention relates to an industrial flue gas desulfurization device and a flue gas treatment method. Background technique [0002] Many industrial productions will produce waste gas with sulfur dioxide, which can only be discharged after desulfurization treatment reaches the standard. [0003] The traditional desulfurization equipment is a vertical desulfurization reaction tower, which is equipped with a multi-layer swirl distribution plate. The lye is pumped to the upper part of the tower and flows down from the swirl plate in turn. The flue gas enters the tower from the bottom of the tower. Going countercurrently, it fully contacts with the desulfurization liquid, and the desulfurization reaction occurs. After desulfurization, the slag solution flows into the sedimentation tank from the bottom of the tower. [0004] Theoretically speaking, the gas-liquid desulfurization tower in the traditional swirling plate type runs in reverse, fully contactin...

Problems solved by technology

[0004] Theoretically speaking, the gas-liquid desulfurization tower in the traditional swirling plate type runs in reverse, fully contacting, and the desulfurization effect is good, but because the tower is equipped with multi-layer swirling plates, and the flue gas flows upstream, the air flow resistance coefficient is very large , the power consumption of the system is high, and the swirl plate is easy to foul, and it cannot be cleaned inside during the production period. After a certain degree, the swirl plate will be completely blocked, causing the entire system to be paralyzed and unable to continue production.
