Abstract

The invention discloses a coke-oven gas negative pressure low temperature sulphur and ammonia removal integrated device, and relates to the technical field of special purifying devie for coke-oven gas. A purifying chamber comprises an ammonia removal chamber and a sulphur removal chamber, and the ammonia removal chamber and the sulphur removal chamber are separated through a transmittance layer; alifting plate is arranged on the side, adjacent to the sulphur removal chamber, of the transmittance chamber, and a concentration monitor is arranged on the lifting plate; the ammonia removal chamberand the sulphur removal chamber are connected with vacuum pumps respectively; the ammonia removal chamber is connected with an ammonia distilling chamber, the ammonia distilling chamber is connectedwith the sulphur removal chamber through a first pipeline, and the sulphur removal chamber is connected with the ammonia removal chamber through a second pipeline. The coke-oven gas sulphur removal and ammonia removal are organically combined, automatic control of the purification process is achieved through arrangement of the transmittance layer and the lifting plate, the device combines the efficient sulphur removal device and the ammonia absorption device to form an efficient, energy-saving and low-consumption new device. The device is the best alternative course of action for purificationof gas with the high hydrogen sulfide content and low ammonia content.

Description

Technical field [0001] The invention relates to the technical field of a special purification device for coke oven gas, in particular to a coke oven gas negative pressure low-temperature desulfurization and ammonia removal integrated device. Background technique [0002] The purification of coke oven gas in the coking industry is achieved through the following steps: coal gas cooling, coal gas denaphthalene, coal gas tar removal, coal gas desulfurization, coal gas deammonia, coal gas debenzene, and coal gas boosting transportation. [0003] The gas desulfurization process has many practical applications, and the processes are divided into three categories, namely wet oxidation desulfurization process, wet absorption-desorption desulfurization process and dry desulfurization process; among them, wet absorption-desorption desulfurization process is used Absorbent is different, divided into ammonia method (absorbent is ammonia water, namely ammonia water desulfurization process) and a...
