Abstract

The utility model discloses a gas heater, including a heater shell, a combustion chamber, a burner and an igniter inside the combustion chamber. The utility model is characterized in that: the internal shell of the heater is provided with a plurality of cross tubes on different vertical plane along the vertical direction; and both ends of the tube are communicated with an annular cavity arranged between the internal and external shells of the heater. The annular cavity arranged between the internal and external shells of the heater is provided with a plurality of vertical radiating pipes evenly distributed along the circumference and both ends of the tube are communicated with the upper and lower parts of the cavity of the internal shell. The utility model, compared with the prior art, has the advantages of simple structure and high thermal efficiency due to the cross tube and the radiating pipe.

Description

A kind of combustion heater

Technical field:

The utility model relates to a kind of hot swapping, particularly a kind of combustion heater.

Background technology:

Crude oil in the petroleum pipeline of oil field needs to heat at temperature lower season, the heater that now generally uses is the resistance-type electric heater, the thermal efficiency is low, consumes power is big, increased the cost of crude oil, and the association combustion gas that the oil well mouth is separated from crude oil is released, and has not only wasted resource but also polluted environment.The patent No. provides a kind of combustion heater for 96238279.5 utility model patent for the combustion gas that utilizes oil well to separate, the heat exchanger of this combustion heater is made up of the head type heat exchanger and grating type heat exchanger three parts on inclined tube-type heat exchanger, top, its complex structure, the thermal efficiency is low, makes this patent fail so far to use in the oil field.

Summary of the invention:

The utility model technical issues that need to address are a kind of simple in structure and combustion heaters that the thermal efficiency is high of design.The technical solution of the utility model is, a kind of combustion heater, it comprises the heater housing, combustion chamber and interior burner and igniter thereof, it is characterized in that: along vertically being provided with the not transverse tube on same vertical plane, the two ends of pipe are communicated with annular chamber between the heater inner housing in the heater inner housing.Be uniformly distributed with vertical radiating tube in the annular chamber between the inner and outer shell of heater along the circumference, the two ends of pipe are connected with the upper and lower of inner housing inner chamber.The utility model is owing to be connected with annular oil cavity between the heater inner and outer shell along vertically being provided with the heatsink transverse pipe in same vertical plane not in the heater inner housing, in annular oil cavity, be evenly equipped with radiating tube, the two ends of pipe are communicated with the upper and lower chamber of heater inner housing respectively, thereby the utility model has advantage simple in structure, that the thermal efficiency is high compared with the prior art.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.Among the figure: 1. burner 2. combustion chambers 3. oil-ins, 4. heater inner housings 5. heater inside and outside shells 6. radiating tubes 7. transverse tubes 8. chimneys 9. oil-outs 10. electric appliance boxes 11. deflection plates.

The specific embodiment:

Combustion heater of the present utility model, in the bottom of heater inner housing 4 is combustion chamber 2, burner 1 and igniter are arranged in it, burner is connected with heater Gas Pipe outward, the edge vertically is provided with three not transverse tubes on same vertical plane 7 in the inner housing above the combustion chamber, its two ends are communicated with annular oil cavity between the inner and outer shell, are uniformly distributed with six vertical radiating tubes 6 in annular oil cavity along the circumference, and the two ends of pipe are connected with the upper and lower of heater inner housing inner chamber respectively.Be respectively equipped with oil-in 3 in the bottom of annular oil cavity with top and be connected with petroleum pipeline with oil-out 9, the top of heater epicoele is connected with chimney 8.The outside of combustion heater is provided with electric appliance box 10, and control igniting and burning and oily temperature parameter control part are arranged in it.The utility model is owing to be provided with the different transverse tube of a plurality of horizontal levels in heater, high-temperature gas there is barrier effect, prolonged the time of carrying out heat exchange with crude oil, radiating tube in the annular oil cavity has increased heat exchange area simultaneously, in annular oil cavity, be provided with deflection plate 11, thereby the utlity model has advantage simple in structure, that the thermal efficiency is high.

Claims (2)

1, a kind of combustion heater, it comprises the heater housing, combustion chamber and interior burner and igniter thereof is characterized in that: along vertically being provided with the not transverse tube on same vertical plane, the two ends of pipe are communicated with annular chamber between the heater inner housing in the heater inner housing.

2, combustion heater according to claim 1 is characterized in that: be uniformly distributed with vertical radiating tube in the annular chamber between the inner and outer shell of heater along the circumference, the two ends of pipe are connected with the upper and lower of inner housing inner chamber.
