Described waste oil cracking rectifier, the mixture of the glass sphere of described catalyzer to be diameter be 10-25 millimeter, Ceramic Balls, alumina balls composition, the distribution of catalyzer is lower thick upper thin, described oil gas vent is communicated with negative pressure, and described well heater is the one in electric heater, hotline heater, molten salt heater.
Waste oil cracking rectifier described above, is connected with cleaning air entraining valve at the top of described rectifying tower.
Described waste oil cracking rectifier, the catalyzer described in it is the mixture of one or more in silica-alumina catalyst, dolomite catalysts, silicon carbide catalyzer.
Described waste oil cracking rectifier, the catalyzer described in it is molecular sieve, as high-end desulfurization agent, A type molecular sieve, X-type molecular sieve.
The utility model in use, waste oil enters reactor from fuel charging valve after first can carrying out degassed process again, fire box temperature should control according to the processing requirement of cut rank, general temperature controls at 40-400 DEG C, when the oil gas vent on rectifying tower adopts negative pressure, its vacuum tightness also will control according to the processing requirement of cut rank, general vacuum degree control is at 50-360Pa, waste oil in reactor is heated, direct or indirect heating can be adopted, well heater can adopt electric heater, hotline heater, one in molten salt heater, favourablely automatically to control, after waste oil in reactor is heated, waste oil generation cracking, gasification, oil gas after gasification enters rectifying tower through ventilation dividing plate, rectifying is carried out under the effect of catalyzer, realize desulfurization, decolouring removal of impurities, oil gas after rectifying enters down one treatment process by oil gas vent.At rectifying tower, the top set temperature sensor of reactor is the rectification temperature of temperature in order to observing response still burner hearth and rectifying tower, the favourable control carrying out temperature, when bottom reactor, the dregs of fat are more, need to open residual cake valve and carry out oil extraction slag, and the dregs of fat are carried out special collection and treatment, catalyzer loads from opening for feed, can discharge from manhole if desired, when catalyzer is subject to severe contamination, pressurized air can be added from cleaning air entraining valve to clean catalyzer, and the slag cleaned out is discharged from residual cake valve, generally catalyzer can not be changed for about 10 years, reactor arranges safety valve, weather gage, vacuum meter, the favourable safe and operation of liquidometer.
The beneficial effects of the utility model, waste oil cracking rectifier of the present utility model, it is rational in infrastructure, the cracking of waste oil, rectifying two kinds of equipment is united two into one, significantly improves the cracking of waste oil, rectification effect, continuous seepage can be carried out, in the oil born again, sulphur content is extremely low, and catalyzer does not change throughout the year, oil yield when can significantly improve waste oil regeneration and quality, reduce the production cost of waste oil regeneration, there is promotional value.
