Abstract

The invention discloses a desulfurization system and method suitable for a complex iron desulfurizer, the desulfurization system suitable for the complex iron desulfurizer comprises a desulfurization tower, the desulfurization tower is communicated with a settling separator, the settling separator is communicated with a low-position regenerator, the settling separator is communicated with a plate frame through a suspension pump, the plate frame is communicated with the low-position regenerator, and the low-position regenerator is communicated with the plate frame. The plate frame is communicated with the preprocessor, the preprocessor is communicated with the metering commercial tank, the metering commercial tank is communicated with the desulfurization low-position tank, the desulfurization low-position tank is communicated with the gas condenser, the gas condenser is communicated with the immersion tank, the regenerator is communicated with the buffer tank, and the buffer tank is communicated with the desulfurization tower through a desulfurization liquid pump. The settling separator is arranged in the system, so that tiny solid particles in the desulfurization pregnant solution of the desulfurization tower are ensured to be held, the solid-liquid ratio of the desulfurization pregnant solution is less than 0.5%, the whole tower is never blocked, the separation of the sulfur-containing suspension is effectively realized, and the system is not blocked any more.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a desulfurization system and method suitable for a complex iron desulfurizer. Background technique [0002] 1. Current status of hydrogen sulfide gas removal technology [0003] Hydrogen sulfide-containing gases mainly include coal chemical gas, coking coke oven gas, petrochemical natural gas, and various refinery gases. Under normal circumstances, the liquid phase removal process is generally adopted. The liquid phase removal process currently adopts the chemical removal method of desulfurization agent under alkaline conditions. According to the difference of desulfurization agent, there are mainly MSQ method, tannin extraction method, titanocobalt method and complex iron method. [0004] The first three types of desulfurizers are widely used in the coal chemical and coking industries due to their low cost of use, but there is also the chronic problem of the accumulation of by-p...
