Abstract

The invention provides a quench tower for a sulphur recycle device. The quench tower comprises a cylindrical quench tower body and a pre-cooling segment connected with the tower bottom of the quench tower body. A gas inlet of the quench tower is formed in the top end of the pre-cooling segment, the top of the quench tower body is provided with a gas outlet, and the top of the quench tower body isprovided with a fresh water supplement port and a circulation water spray inlet. A liquid outlet of the quench tower is connected with an inlet of a circulation pump, an outlet of the circulation pumpcommunicates with spray devices through pipes, and the spray devices are located in the pre-cooling segment and the quench tower body separately.

Description

technical field [0001] The invention relates to a quenching tower. Specifically, it is a quench tower used for rapid cooling of high-temperature flue gas, especially suitable for the quench tower of a sulfur recovery unit. Background technique [0002] The function of the sulfur recovery unit is to recover sulfur from the acid gas containing hydrogen sulfide produced in the refining process by appropriate process methods, so as to realize clean production, turn waste into treasure, reduce pollution and protect the environment. However, the tail gas after sulfur recovery still contains harmful substances such as sulfur and cannot be directly discharged into the atmosphere. Therefore, the sulfur recovery unit is often equipped with an acid gas treatment unit, so that the tail gas of the unit can be discharged up to the standard. The quench tower is one of the equipment used for acid gas treatment. [0003] Generally, the temperature of the tail gas from the incinerator of t...
