Embodiment 1
[0028] See figure 1 As shown, it is a device for co-processing organic fluorine and terpene residues by plasma cracking provided in this embodiment. The device includes a cracking furnace 1, and the cracking furnace 1 has a furnace body in the shape of a vertical cylinder. A high temperature zone 2 in the upper section of the furnace body and a low temperature zone 3 arranged in the lower part of the high temperature zone; a plasma torch 4 is vertically arranged at the center of the upper end face of the furnace body, and the port of the plasma torch 4 is arranged in the high temperature zone 2 in the furnace body. Plasma uses the plasma torch or plasma beam generated between the electrodes to generate high temperature. The plasma torch or plasma beam can be generated by AC, DC, power frequency and high frequency methods. The arc core temperature is very high and can achieve high temperature instantly. The power is turned on, and the current starts arcing at the port of the pl...
Embodiment 2
[0038] The tetrafluoroethylene raffinate and the terpene raffinate are treated synergistically, as follows:
[0039] The collaborative treatment is carried out in the cracking furnace, and the negative pressure of the cracking furnace is controlled at -300Pa;
[0040] Turn on the power supply, and the current will strike the arc at the port of the plasma spray gun to form a high-temperature arc area. When the plasma arc is heated to above 2000 °C, the tetrafluoroethylene residue and terpene residue, tetrafluoroethylene residue, terpene residue, terpene residue and terpene residue are simultaneously introduced The mass ratio of the alkene residue is 30kg / h:13kg / h. The tetrafluoroethylene residual liquid is composed of: 80%-95% of octafluorocyclobutane, 5%-10% of perfluoroisobutene, about 5% of tetrafluoroethylene or its polymer, and a small amount of chlorodifluoromethane; The main component of the alkene residue is C 10 H 16 and its analogs, the content is about 80%, the ot...
Embodiment 3
[0046] The hexafluoropropylene raffinate and the terpene raffinate are treated synergistically, as follows:
[0047] The synergistic treatment is carried out in the cracking furnace, and the negative pressure of the furnace chamber is controlled at -900Pa;
[0048] Turn on the power supply, and the current will strike the arc at the port of the plasma spray gun to form a high-temperature arc area. When the temperature of the plasma arc is above 2000 °C, the hexafluoropropylene residue and terpene residue, hexafluoropropylene residue and terpene are simultaneously introduced. The mass ratio of the alkene residue is 40kg / h:17kg / h. Among them, the composition of the hexafluoropropylene residual liquid is: about 90% of perfluoroisobutene, about 10% of octafluorocyclobutane, and a small amount of hexafluoropropylene. The main component of terpene raffinate is C 10 H 16 and its analogs, the content is about 80%, the other is heavy components and a small amount of water, and the h...
