A quiet compound desulfurization tower

Abstract

The invention discloses a quiet compound desulfurizing tower, which comprises two liquid inlet pipes. The quiet compound desulfurizing tower is characterized in that the two liquid inlet pipes comprise a first liquid inlet pipe and a second liquid inlet pipe, wherein the first liquid inlet pipe is installed on the upper part of a first-layer quiet adsorption plate and vertically enters the tower; the liquid outlet of the first liquid inlet pipe in the tower faces downwards; the second liquid inlet pipe is installed in the middle part between a second-layer quiet adsorption plate and a third-layer quiet adsorption plate and vertically enters the tower, and the liquid outlet of the second liquid inlet pipe in the tower faces upwards; and an efficient atomization nozzle is installed on each of the outlet of the liquid inlet pipes; the quiet adsorption plate comprises plate holes which are longitudinal small holes which are regularly distributed and penetrate through the quiet adsorption plate; overflowing pipes are installed on one side of the quiet adsorption plate and are longitudinal steel pipes which penetrate through the quiet adsorption plate. The diameter of the tower is 2.6m, the height of the tower is 32m, inlet sulfuretted hydrogen is 200mg / Nm<3>, solution circulation volume is 196m<3> / h, and tower resistance is less than 0.02Mpa under a working condition that pressure is 2.3MPa; throughput is 100000Nm<3> / h, and sulfuretted hydrogen contents in tower outlet gas are controlled to be below 2 mg / Nm<3>. The outlet sulfuretted hydrogen gas is below 2 mg / Nm<3>, and the efficiency is 99% or above.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment and relates to a compound desulfurization tower, in particular to a quiet compound desulfurization tower; it is especially suitable for pressurized wet desulfurization gas-liquid mass transfer in the pressurized wet desulfurization process in the chemical industry. Background technique [0002] In order to meet the requirements of process technology and environmental protection, the requirements for sulfur content in process gas in chemical production systems are becoming more and more stringent. [0003] At present, there are two main types of desulfurization towers for wet desulfurization: pressurized packed towers and tubular bubble towers. The packing specifications and models used in the packed tower are different, and the mass transfer area is different. The pressurized packed tower generally has the characteristics of small superficial gas velocity, large desulfurization tower di...
