Description
Technical field
The invention belongs to regenerating waste oil process field, more particularly to used oil pyrolysis installation.
Background technology
As China's industrialization and modernization construction are promoted, the consumption of machine oil also significantly rises, and machine oil difference combustion
The burning consumption of oil, but be mixed with substantial amounts of impurity and cause to use.These used oil are burnt in the prior art
Processing carries out the distillation of reheating solution to isolate the cuts such as gasoline.Used oil is nonflammable fully, and effectively utilization is not simply failed to
Its calorific value, and easily generate a large amount of flue gases and cause environmental pollution.The pyrolytic process of current used oil is more rough, using heating
Pipe heats to it, but is due to that the temperature of heating tube exists in machine oil and transmits uneven phenomenon, close to heating
The machine oil of pipe is easily excessively heated and coking and is deposited in heating pipe outer wall, and the heat transference efficiency of heating tube is not only reduced again,
And timing progress coke cleaning operation is also needed to, therefore cause the high cost of used oil pyrolysis processing, low-yield phenomenon.
The content of the invention
It is an object of the invention to provide a kind of used oil pyrolysis installation, the present invention is simple in construction, ingenious in design, can be effective
Promote combustion tube Homogeneouslly-radiating in heating tank, substantially reduce the probability of happening of burning pipe outer wall coking phenomenon.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
Used oil pyrolysis installation, described device includes Horizontal Heating tank, and through the combustion tube of Horizontal Heating pot bottom, burning
Pipe one end connects with combustor and is provided with exhaust outlet, and the other end is provided with closure door；The one end of heating tank away from combustor is provided with oil-feed
Pipe and flowline, the tube wall disk that combustion tube is located in heating tank set snakelike mozzle.
It is preferred that, the import of the snakelike mozzle is connected with oil inlet pipe, and outlet inside heating tank with connecting, snakelike water conservancy diversion
Pipe is along combustion tube is axially arranged and bending part is towards combustion tube two ends.
It is preferred that, the outlet of the snakelike mozzle be located at the top of combustion tube and with the spray bar that is radially arranged along combustion tube
Connection.
It is preferred that, the snakelike mozzle includes the left semicanal and right semicanal that relative combustion pipe axisymmetrical is distributed, left and right
The import of semicanal is all connected with oil inlet pipe, exports and is all connected with spray bar.
It is preferred that, the spray bar is provided with several, and the oil spout of adjacent spray bar is in opposite direction.
It is preferred that, described device includes several convection tubes set around combustion tube periphery.
It is preferred that, end of the heating tank provided with oil inlet is provided with thermal insulation layer.
It is preferred that, the heating tank above described oil inlet is provided with overflow pipe and oil discharge pipe.
The course of work of the present invention is as follows：Fuel oil penetrating combustion tube after combustor will be lighted is burnt, and work people
The used oil that member is injected after filtering by oil inlet pipe into heating tank, used oil passes through the left and right semicanal of snakelike mozzle respectively
Sprayed afterwards from spray bar, and the combustion heat is transferred to the used oil in heating tank in the combustion tube that said process is absorbed.Heating tank
Interior used oil heat absorption is pyrolyzed into the lighter gasoline of cut or other oily products, is then exported from oil discharge pipe.If in heating tank
Used oil it is excessive when, can be drained into from overflow pipe extraneous and be collected and recycle, the used oil after pyrolysis is from oil discharge outlet
Discharge.With the burning of fuel oil in combustion tube, certain lime-ash can be generated, cleaning can be removed at closure door.Combustion tube internal combustion
The waste gas of material oil firing generation drains into the external world from the flue of exhaust ports.Likewise, can around the convection tube that combustion tube periphery is set
With the combustion heat in effective peritropous used oil radiant combustion pipe, the pyrolysis efficiency of used oil is improved.
The present invention compared with prior art, has the following advantages that：
1）Water conservancy diversion is carried out to used oil using the snakelike mozzle being sticked in burning pipe outer wall, can effectively absorb and shift burning
The heat of pipe outer wall, prevents machine oil from being influenceed and coking by the high temperature of burning pipe outer wall；
2）The combustion heat in combustion tube is conducted and homogeneous radiation using flow-type machine oil and convection tube so that in heating tank
Used oil be integrally heated, be pyrolyzed, improving pyrolysis effect simultaneously reduces energy consumption.
3）Snakelike mozzle uses symmetrically arranged left and right half tubular construction, shortens the flowing stroke of machine oil, prevents snakelike
The machine oil of mozzle produces coking phenomenon in pipe because the stroke of catalytic combustion pipe outer wall is long, and can quickly conduct combustion
Burn the heat of pipe；
4）The injection direction of spray bar is inconsistent, and machine oil in heating tank can be promoted to produce convection current, further improve machine oil it
Between heat conduction efficiency.
