Abstract
The invention discloses a light-oil recovery device for a continuous spent-lubricating-oil regeneration device. The light-oil recovery device comprises a tube furnace. The spent lubricating oil is pretreated and fed into the tube furnace, then the spent lubricating oil is heated in the tube furnace and fed into a dehydration kettle, and the spent lubricating oil made to flow through a first condenser so as to be condensed and is finally treated by a waste-oil tank and a vacuum work tank to obtain water and light oil. The crude oil from the dehydration kettle is fed into an oil condenser, and at the same time, the oil heated in the tube furnace is subjected to pyrolysis in a distillation kettle. Gases generated from pyrolysis are subjected to heat exchange through a gas delivery pipe and the oil condenser and are cooled by a water condenser, and then the light fuel oil is collected in an oil storage tank. According to the light-oil recovery device, because the crude oil from the dehydration kettle and the gases generated from pyrolysis in the distillation kettle are subjected to heat exchange in the oil condenser, the crude oil from the distillation kettle is heated, and the gases generated from pyrolysis in the dehydration kettle are cooled, the energy can be fully utilized, and the expenses spent in heating the crude oil and cooling the gases generated from pyrolysis in the dehydration kettle are reduced.
Description
Technical field
The invention belongs to waste lubricating oil and reclaim field, be specifically related to a kind of device that reclaims waste lubricating oil.
Background technology
Taking waste lubricating oil as example, about 200,000,000 of the automobile that China is operating at present, each car changes machine oil for 1 year 2 times, is 3 liters at every turn, and the waste lubricating oil amount of changing is every year 200,000,000 × 2 × 3 liters=1,200,000,000 liters.If these waste and scraps are reclaimed, can save a large amount of costs every year, and reduce environmental pollution.A lot of factories, by these salvage material, are processed as processed oil by waste lubricating oil recovery system and are reused.In removal process, can produce light oil, light-weight fuel oil, heavy fuel oil (HFO), lube base wet goods, in the process of recovery light oil, need to get back to tube furnace from dehydrating kettle crude oil out heats again, and need to carry out cooling from still kettle reacted gas out, these two processes are not occured simultaneously, and all need again to waste energy.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of light oil recovery device of the continous way regenerator for waste lubricating oil of saving energy is provided.
For achieving the above object, technical scheme of the present invention realizes in the following manner: a kind of light oil recovery device of continous way regenerator for waste lubricating oil, comprise tube furnace, waste lubricating oil is through entering tube furnace after pre-treatment, after tube furnace is heated, enter after dehydrating kettle, by condensation after the first condenser, finally by by water oil tank and the processing of vacuum work tank, obtain water and lightweight oil.The crude oil of coming from dehydrating kettle enters oil cooling condenser, oil cracking in still kettle of heating in tube furnace simultaneously, and the gas after cracking carries out heat exchange through pneumatic tube and oil cooling condenser, more cooling by water condenser, collects light-weight fuel oil in storage tank.
Described tube furnace is transverse pipe type stove, and tube furnace is connected with still kettle by oil pump, is connected with weir tank in still kettle.
Described tube furnace comprises body of heater, and upper of furnace body is provided with hopper, is provided with some heating tubes in body of heater, and heating tube is connected with control valve.
In the present invention, carry out heat exchange from reacted gas out in crude oil out of dehydrating kettle and still kettle at oil cooling condenser, in still kettle, crude oil is out heated, dehydrating kettle reacted gas is out cooled, can make full use of energy, reduce the expense of crude oil heating and dehydrating kettle reacted gas cooling out.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of tube furnace.
Fig. 3 is the schematic top plan view of Fig. 2.
Embodiment
As shown in Figure 1, a kind of light oil recovery device of continous way regenerator for waste lubricating oil, comprise tube furnace 1, it is characterized in that: waste lubricating oil is through entering tube furnace 1 after pre-treatment, after tube furnace 1 is heated, enter after dehydrating kettle 2, by the rear condensation of the first condenser 3, finally by being processed by water oil tank 4 and vacuum work tank 5, obtain water and lightweight oil.The crude oil of coming from dehydrating kettle 2 enters oil cooling condenser 6, oil cracking in still kettle of tube furnace 1 interior heating simultaneously, gas after cracking carries out heat exchange through pneumatic tube and oil cooling condenser 6, more cooling by water condenser 20, in storage tank 12, collects light-weight fuel oil.
Described tube furnace 1 is transverse pipe type stove, and tube furnace 1 is connected with still kettle 11 by oil pump 14, is connected with upflow tube 15 in still kettle 11.
Described tube furnace 1 comprises body of heater 1-1, and body of heater 1-1 top is provided with hopper 1-2, is provided with some heating tube 1-4 in body of heater 1-1, and heating tube 1-4 is connected with control valve 1-3.
Tube furnace 1 described in the present invention is transverse pipe type stove, and tube furnace 1 is connected with still kettle 11 by oil pump 14, is connected with upflow tube 15 in still kettle 11.Being conveyed into tube furnace from still kettle 11 crude oil out through oil pump 14 heats.This structure, can fuel economy 20% left and right compared with traditional water condenser structure.
