Among the figure: 1, sulfur furnace, 2, pyrolyzer, 3, connecting tube, 4, air supply duct, 5, gas blower, 6, venting port, 7, the air outlet, 8, inlet mouth, 9, communication port, 10, coil pipe.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 1; A kind of residual heat using device of producing sulfan; Comprise sulfur furnace 1, pyrolyzer 2, be connected with gas blower 5 on the blast pipe of sulfur furnace 1, sulfur furnace 1 is provided with air outlet 7; Pyrolyzer 2 is provided with inlet mouth 8, is provided with connecting tube 3 between air outlet 7 and the inlet mouth 8; Connecting tube 3 is provided with communication port 9, and said induced draft fan 5 also is connected with communication port 9 through air supply duct 4; The top of described pyrolyzer 2 is provided with venting port 6.Be lined with heat-resisting thermal insulation layer in the described connecting tube 3.
During production, produce 900 ℃ SO in the sulfur furnace 1
2High-temperature furnace gas drains into the connecting tube 3 from air outlet 7; Gas blower 5 is delivered to air in the connecting tube 3 along air supply duct 4; After making high-temperature furnace gas in the connecting tube 3 be cooled to 750 ℃-780 ℃ with air mixed by in the inlet mouth 8 entering pyrolyzer 2; High-temperature furnace gas is with the acetic gas in heat transferred pyrolyzer 1 inner coil pipe 10; Make it cracking at high temperature and generate ketene, the gas that has discharged heat is discharged the subsequent production processing unit that gets into sulfan from the venting port 6 at pyrolyzer 2 tops, carries out next step reaction.At the heat-resisting thermal insulation layer of connecting tube 3 liners, make heat in connecting tube 3, be difficult for loss.
The utility model makes the waste heat of producing the sulfan generation obtain the use of more optimizing, and the waste heat that produces in the production sulfan process is used for the production of ketene.Adopted medium pressure boiler device and steam turbine power generation to recycle in the past and produce the waste heat that sulfan produces, its investment cost, working cost, maintenance cost are all higher, demand strict technology; And the residual heat using device of the described production sulfan of employing the utility model; Make the interlock production of sulfan and ketene, simple in structure, investment, operation and maintenance cost is all lower; Technical requirements is low, and has reduced the production cost of ketene.The utility model is fit to Chemical Manufacture type enterprise to be used.
