Description

A kind of vertical combustion gas hot oil furnace

The utility model relates to oil transportation equipment, especially a kind of vertical combustion gas hot oil furnace.

In the prior art, the heating of oil transportation process need is to improve its flowability, and mostly the firing equipment of oil is to adopt the combustion gas hot oil furnace, present combustion gas hot oil furnace generally is a horizontal chamber furnace (oven), and what wherein the heating oil pipe in the stove adopted is coil, and the problem that the combustion gas hot oil furnace of this structure exists is that floor space is bigger, because what deep fat was effective is coil, so the resistance of its oil flow is also bigger, and the combustion gas hot oil furnace of this structure is also extremely difficult and dangerous when maintenance.

The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of vertical combustion gas hot oil furnace technical scheme is provided, and the combustion gas hot oil furnace floor space of this scheme is little, and the flow resistance of oil is little, and for ease of maintenaince.

For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.

Description of drawings:

Fig. 1 is the part sectional structure schematic diagram of the utility model embodiment:

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic.

By accompanying drawing as can be seen, the vertical combustion gas hot oil furnace of this programme, mainly include body of heater 4, fire door 2, combustion chamber 3, oil-in 10, oil-out 8, water inlet 18, delivery port 9, chimney 11 and oil pipe, the characteristics of this programme are that described body of heater 4 is vertical type cylinder stavings, body of heater end socket 7 is arranged at its top, oil-in 10 is arranged on body of heater end socket 7, oil-out 8 and delivery port 9, there is a vertical combustion chamber 3 to communicate in the inside of body of heater 4 with the fire door 2 and the combustion chamber ash removing opening 1 of bottom, 3 the top connection one backhaul flue 16 straight down in the combustion chamber, there are flue connection pipe 15 and backhaul flue ash removing opening 17 to be connected with backhaul flue 16 in the bottom of backhaul flue 16, periphery at combustion chamber 3 and backhaul flue 16 has oil pipe 5 outside helical form inner oil tube 6 and the helical form, inner oil tube 6 and outer oil pipe 5 are connected in the bottom and communicate, the top of outer oil pipe 5 is connected with oil-in 10, and the top of inner oil tube 6 is connected with oil-out 8, has water inlet 18 to communicate with the inner chamber of body of heater 4 in the bottom of body of heater 4.In fire door 2 corresponding sides of described body of heater 4 smoke outlet flue 13 of a chimney-like is arranged, the bottom of this smoke outlet flue 13 is connected with flue connection pipe 15, also has smoke outlet flue ash removing opening 14 simultaneously, is connected with chimney 11 at the top of smoke outlet flue 13.On the outer wall of described smoke outlet flue 13, there is smoke outlet flue water jacket 12 to communicate with the inner chamber of body of heater 4.

According to as can be known to the narration of such scheme, be vertical type cylinder shape staving because the body of heater in this scheme adopts, therefore, its floor space is little, and the oil pipe that deep fat is used then is spiral helicine inner oil tube and outer oil pipe, so its flow resistance to oil is little.Because this programme adopts is vertical body of heater and vertical combustion chamber and vertical backhaul flue, the periphery of combustion chamber and backhaul flue be heated inner oil tube and outside oil pipe, and inner oil tube and outer oil pipe all are connected on the body of heater end socket, this structure is when maintenance, inside and outside oil pipe can propose body of heater together in company with the body of heater end socket, but convenient for maintaining, in addition, inside and outside oil pipe connects with can adopt flange into and out of being connected of hydraulic fluid port, so can employ firearms such as electrogas welding when changing oil pipe, this is safe to maintenance.This shows that the utility model compared with prior art has substantive distinguishing features and progress, its implementation result also is conspicuous.
