Embodiment

[0017] As shown in Figure 1, a combined internal heat extraction sulfur recovery reactor includes a tower body, the top of the tower body is provided with an exhaust gas outlet 2, and the bottom of the tower body is provided with a process gas inlet 1. According to the sequence of the process flow, the tower body starts from the bottom The primary reformer 15, the secondary reformer 11, and the hydrogenation reactor 7 are successively arranged at intervals at the top. Between the primary reformer 15 and the secondary reformer 11, a primary process gas heater 12, a primary condenser 13, and a baffle 14-2 are sequentially arranged from top to bottom; in order to monitor the primary process gas heater 12 , the temperature of the primary condenser 13, thermocouples 11-3, 12-1 are also set respectively; the gas-rising port 14 is set on the baffle plate 14-2, and the side wall of the tower body above the baffle plate 14-2 is provided with a liquid sulfur outlet 14 -1, the primary co...

Abstract

The invention provides a combination-typed internal heating sulfur recovery reactor, belonging to the technical field of sulfur recovery. The reactor comprises a tower body, the top of which is provided with a tail gas outlet and the bottom of which is provided with a process gas outlet. The reactor is characterized in that according to the process flow sequence, a primary converter, a secondary converter and a hydrogen adding reactor are sequentially arranged in the tower body at interval from bottom to top; a process gas heater and a condenser are sequentially arranged between the primary / secondary converter and the hydrogen adding reactor from top to bottom. The equipment achieves the same process effect with the equipment of the prior art, reduces the quantity of the process equipment, simplifies the process pipelines, and saves the occupied land of the device.

Description

technical field [0001] The invention belongs to the technical field of sulfur recovery, and in particular relates to a combined internal heating sulfur recovery reactor. Background technique [0002] In domestic and foreign sulfur recovery units in the petrochemical and coal chemical industries, the Claus sulfur recovery process of high-temperature thermal reaction and two-stage catalytic reaction is generally used for the sulfur production part, and the hydrogenation reduction absorption process is used for the tail gas part. The sulfur recovery unit includes three reactors, namely the primary and secondary converters of the sulfur production part and the hydrogenation reactor of the tail gas part. Exothermic reactions occur in the three reactors, which are used for the recovery of the primary and secondary converters. The sulfur produced and the H produced in the absorption hydrogenation reactor 2 S, it is necessary to condense and cool the reaction discharge material, an...
