Hydrogen sulfide absorbing tower

Abstract

The invention discloses a hydrogen sulfide absorbing tower. The hydrogen sulfide absorbing tower comprises a complex iron storage tank, a first spraying tower, and a second spraying tower; the first spraying tower and the second spraying tower are communicated with the complex iron storage tank; the top of the first spraying tower is provided with a gas inlet and a spraying device; the top of thesecond spraying tower is provided with a gas outlet and a spraying device; a material inlet pipe, a material outlet pipe, and a circulating pipe are arranged on the complex iron storage tank; the circulating pipe is connected with the spraying devices through a circulating pump. In applications, a complex iron solution is taken as a spraying solution for absorption of hydrogen sulfide. Compared with the prior art, the advantages are that: real-time monitoring of the concentration change of the spraying solution is not needed, multi-stage reaction absorption is capable of ensuring complete absorption of hydrogen sulfide, blocking of pipelines by reaction products is avoided, the reaction products are high in economical value, labor intensity is reduced greatly, and economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a hydrogen sulfide absorption tower. Background technique [0002] Viscose fiber production process will produce waste gas containing a large amount of hydrogen sulfide and carbon disulfide. If it is directly discharged, it will not only waste resources seriously, but also cause serious pollution to the environment around the factory. Sprinkle a large amount of sodium carbonate or sodium hydroxide solution to make it react with hydrogen sulfide in the exhaust gas, so as to purify the exhaust gas and prevent environmental pollution; the current absorption liquid spraying device adopts a single gas-liquid downstream contact or countercurrent contact. Generally, the lye spray device has multiple atomizing nozzles built in to increase the contact area between the absorption liquid and the exhaust gas, and improve the removal efficiency of hydrogen sulfide....
