Problems solved by technology

[0003] In the current sulfur recovery device, the liquid sulfur formed after the process gas is condensed and cooled is collected through the sulfur sealing tank. The height of the sulfur sealing tank is about 4 meters. In order to meet the process requirements, the sulfur sealing tank must be installed nearly three meters below the ground In the deep tank pool, the liquid sulfur directly flows into the liquid sulfur pool operated at normal pressure after being sealed with sulfur. In order to ensure that the liquid sulfur can flow into the liquid sulfur pool by itself, the liquid sulfur pool must also be installed below the ground. It is a concrete structure, which constitutes a harmful factor for soil pollution

Abstract

The invention discloses a liquid sulphur collecting method suitable for a sulfur recovery device. Process gas of the sulphur recovery device enters a process gas condensate cooler to carry out gas-liquid separation; condensed and separated gas enters the next stage of reaction or condensate cooling system after a liquid sulphur catcher traps the liquid sulphur; the condensed liquid sulphur is collected by a liquid sulphur collector below the process gas condensate cooler; the collecting process is controlled by a process operation module; the collected liquid sulphur is directly delivered to a sealed liquid sulphur middle tank with pressure; the liquid sulphur is fed to a liquid sulphur treatment system after passing through a liquid sulphur degassing pump after gas-liquid secondary separation; and the separate gas is separated from the final stage of process gas condensate cooler and enters a tail gas treatment unit together with the tail gas which is further separated by a tail gas delivery tank. By adopting the technology, arrangement of a sulphur sealing tank, a sulphur sealing tank pond and a liquid sulphur pond is concealed; the technologic process is shortened; the investment on the equipment is reduced; and pollution of the liquid sulphur, the hydrogen sulfide and related treatment technologies on the soil, environment and ground water quality is partially removed.

Description

technical field [0001] The invention relates to the technical field of sulfur recovery, in particular to a liquid sulfur collection method suitable for a sulfur recovery device. Background technique [0002] my country has always advocated energy conservation and emission reduction, strictly controlled atmospheric sulfur dioxide emissions, paid attention to environmental protection, and protected soil from pollution. [0003] In the current sulfur recovery device, the liquid sulfur formed after the process gas is condensed and cooled is collected through the sulfur sealing tank. The height of the sulfur sealing tank is about 4 meters. In order to meet the process requirements, the sulfur sealing tank must be installed nearly three meters below the ground In the deep tank pool, the liquid sulfur directly flows into the liquid sulfur pool operated at normal pressure after being sealed with sulfur. In order to ensure that the liquid sulfur can flow into the liquid sulfur pool b...
