Description
Technical Field
The utility model belongs to the technical field of the chemical industry, a sulphur recovery system is related to, in particular to sulphur recovery tail gas system.
Background
The claus process is one of the methods for removing hydrogen sulfide generated during combustion of fossil fuel and geothermal power generation, and the generated tail gas contains a small amount of sulfide, does not meet the existing environmental protection standard and cannot be directly discharged, so that an incinerator is arranged to fully combust the tail gas, and then the tail gas is refrigerated by extremely cold air and discharged into the atmosphere. However, the process does not consider the problem of recovering the waste heat after the tail gas is burnt in the design, the temperature of the gas discharged by the fully burnt incinerator is very high, a lot of waste heat is not fully applied, and the extremely cold air refrigeration equipment causes a large amount of energy consumption.

Further: the waste heat recovery equipment comprises an inlet pipeline, heat exchange equipment and an outlet pipeline, wherein one end of the inlet pipeline is connected with an exhaust port of the Claus equipment tail gas incinerator, and the other end of the inlet pipeline is connected with an inlet of the heat exchange equipment; and the outlet of the heat exchange equipment is connected with an outlet pipeline.
Further: a tube side pipeline and a shell side pipeline are arranged in the heat exchange equipment, and the tube side pipeline is positioned in the shell side pipeline; the inlet of the tube pass pipeline is connected with the inlet pipeline, the outlet of the tube pass pipeline is connected with the outlet pipeline, and the shell pass pipeline is communicated with cooling water.
Further: the system also comprises a liquid sulfur heat tracing pipe network, and the liquid sulfur heat tracing pipe network is connected with an outlet of the outlet pipeline.
Further: the outlet pipeline comprises two straight pipes and an elbow pipe, and the two straight pipes are connected to two ports of the elbow pipe.
Further: the bent pipe is a 90-degree bent pipe.
Further: still include the outlet valve, the outlet valve sets up in the middle of the export pipeline.
Further: the outlet valve is a gate valve.
Beneficial effects of the utility model
The heat exchange boiler and the pipeline are added on the basis of the existing equipment combination, waste heat is fully utilized, the prepared steam can be introduced into the recovery steam pipe network nearby and utilized as low-pressure steam, the equipment is simple in structure and convenient to install, waste gas heat energy is fully utilized, and the beneficial effects of saving energy and fully utilizing energy are achieved.
Drawings
Fig. 1 is an overall layout of a claus tail gas reaction waste heat application apparatus.
Detailed Description
The present invention is described in detail below with reference to fig. 1:
in the original tail gas process, the tail gas (500 ℃, gas quantity 4000 Nm) which is not diluted and cooled by air in an incinerator is discharged3H, pressure 0.003MPaG, component (V)%: CO 22—39.89％、N2—33.05％、O2—3.7％、H2O-23.36%, and waste heat recovery equipment is added after the incinerator, and the waste heat recovery equipment comprises an inlet pipeline, a heat exchange boiler, an outlet pipeline and a steam pipe network. One end of the inlet pipeline is connected with an exhaust port of the Claus equipment tail gas incinerator, and the other end of the inlet pipeline is connected with heat exchange equipment; the boiler is internally provided with a tube pass pipeline and a shell pass pipeline, an inlet pipeline is connected with the tube pass pipeline, boiler water is introduced into the shell pass of the boiler, high-temperature and high-pressure incineration gas is cooled by the boiler water in the shell pass and then is reduced in temperature and pressure, and the incineration gas is introduced into an outlet pipeline, and the temperature of the incineration tail gas is reduced after passing through the boilerThe energy is reduced, and the pressure is 0.7MPaG after temperature reduction.
The steam after the cooling gets into 0.7MPaG steam pipe network through the outlet pipe way, and in order to facilitate the transmission low pressure steam, the outlet pipe way includes two straight tubes and an return bend, the return bend is 90 return bends, sets up the gate valve on one of them straight tube and adjusts steam flow.
