Oil inlet pipe and flowline, the tube wall disk that combustion tube is located in heating tank set snakelike mozzle.
Preferably, 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 axially arranged along combustion tube and bending part is towards combustion tube both ends.
Preferably, the outlet of the snakelike mozzle is positioned at combustion tube top and the spray bar with being radially arranged along combustion tube
Connection.
Preferably, the snakelike mozzle includes the left semicanal of relative combustion pipe axisymmetrical distribution and right semicanal, left and right
The import of semicanal is all connected with oil inlet pipe, exports and is all connected with spray bar.
Preferably, the spray bar is provided with several, and the oil spout of adjacent spray bar is in opposite direction.
Preferably, described device includes several convection tubes set around combustion tube periphery.
Preferably, end of the heating tank provided with oil inlet is provided with thermal insulation layer.
Preferably, the heating tank above described oil inlet is provided with overflow pipe and oil discharge pipe.
The course of work of the present utility model is as follows：Fuel oil penetrating combustion tube after combustor will be lighted is burnt, work
Make the used oil that personnel are injected after filtering by oil inlet pipe into heating tank, used oil passes through the left and right of snakelike mozzle respectively
Sprayed after semicanal from spray bar, and the combustion heat in the combustion tube of said process absorption is transferred to the used oil in heating tank.Add
Then used oil heat absorption pyrolysis in hot tank exports into the lighter gasoline of cut or other oily products from oil discharge pipe.If heating
When used oil in tank is excessive, the external world can be drained into from overflow pipe and is collected and recycles, the used oil after pyrolysis is from row
Hydraulic fluid port is discharged.With the burning of fuel oil in combustion tube, certain lime-ash can be generated, cleaning can be removed at closure door.Combustion tube
The waste gas of fuel oil firing generation drains into the external world from the flue of exhaust ports.Likewise, the convection current set around combustion tube periphery
Pipe can be in effectively peritropous used oil radiant combustion pipe the combustion heat, improve the pyrolysis efficiency of used oil.
The utility model 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, effectively can absorb and shift
The heat for pipe outer wall of burning, prevent machine oil from being influenceed and coking by the high temperature of burning pipe outer wall；
2）Using flow-type machine oil and the combustion heat in combustion tube is conducted convection tube and homogeneous radiation so that heating
Used oil in tank is integrally heated, is pyrolyzed, and improves pyrolysis effect and 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 the machine oil in heating tank can be promoted to produce convection current, further improve machine
Heat conduction efficiency between oil.
