Description

Three-dimensional ribbed pipe preheater for oil field gas injection boiler

Technical Field

The utility model relates to a three-dimensional ribbed pipe preheater of oil field gas injection boiler.

Background

At present, when an oil field steam injection boiler works, the tail end of the steam injection boiler generally has overhigh exhaust gas temperature, the exhaust gas temperature is 120-200 ℃, the heat loss is overlarge, and the energy waste is caused; the gas injection boiler uses boiler water, the feed water temperature changes along with the change of the environmental temperature, the heating is improved from the lower environmental temperature to the steam temperature used for gas injection production, and the energy loss is larger; the gas injection boiler uses air for participating in boiler combustion, changes along with the change of environmental temperature, and is heated from lower environmental temperature to the combustion temperature used for gas injection production, so that energy loss is caused.

Disclosure of Invention

An object of the utility model is to provide a three-dimensional ribbed pipe preheater of oil field gas injection boiler can improve the heat utilization rate of gas injection boiler, reduces energy loss.

The utility model aims at realizing like this, a three-dimensional ribbed pipe preheater of oil field gas injection boiler, including preheater box and three-dimensional ribbed pipe, steam injection boiler's outlet duct is being connected to preheater box bottom surface, it discharges fume the pipe to be set up on the preheater box top surface, horizontal interval is setting up a plurality of three-dimensional ribbed pipes side by side in the preheater box, the entrance point of three-dimensional ribbed pipe is all opened and is located preheater box outside portion, the exit end of three-dimensional ribbed pipe is concentrating and is being connected a preheater tube, an air heating case is being connected to preheater tube one end, the heliciform water pipe is being set up in the air heating case, the water pipe is linked together with steam injection boiler's inlet tube, a steam injection boiler intake pipe of installing the air-blower is being connected to air heating case's bottom, this intake pipe is linked together with steam injection boiler's air door.

By adopting the structure of the utility model, the over-high exhaust gas temperature at the tail end of the gas injection boiler is fully recycled, the heat dissipation energy is optimally utilized, the heat loss of the gas injection boiler can be greatly reduced, and the heat efficiency of the boiler is improved; the method has the advantages that the overhigh exhaust gas temperature at the tail end of the gas injection boiler is recycled to heat boiler feed water, the boiler feed water is ensured to be always at a constant value, the energy consumption of the gas injection boiler participating in combustion is reduced, the energy loss of the gas injection boiler is reduced, and the energy-saving purpose is achieved; the air temperature before the gas injection boiler enters the hearth is heated by recycling the overhigh exhaust gas temperature at the tail end of the gas injection boiler, so that the temperature of the air entering the hearth of the gas injection boiler is always kept at a constant value, the energy consumption of the gas injection boiler participating in combustion is reduced, the energy loss of the gas injection boiler is reduced, and the energy-saving purpose is achieved; the excessively high exhaust gas temperature at the tail end of the gas injection boiler is recycled, so that the exhaust gas emission of the gas injection boiler is greatly reduced, the emission of toxic and harmful gases is reduced, and the purposes of protecting the environment and reducing emission are achieved.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention.

Detailed Description

A three-dimensional ribbed tube preheater of an oil field gas injection boiler is shown in figure 1 and comprises a preheater box body 1 and three-dimensional ribbed tubes 2, wherein the three-dimensional ribbed tubes 2 are in the prior art, and fins are densely distributed on the inner surface and the outer surface of a tube body of the preheater. The bottom surface of the preheater box body 1 is connected with an air outlet pipe of the steam injection boiler 9, and the top surface of the preheater box body 1 is provided with a smoke exhaust pipe. Horizontal interval is setting up a plurality of three-dimensional ribbed pipe 2 side by side in the preheater box 1, the entrance point of three-dimensional ribbed pipe 2 is all opened and is located 1 outside portion of preheater box, the exit end of three-dimensional ribbed pipe 2 is concentrating and is being connected a preheater 4, an air heating box 5 is being connected to preheater 4 one end, set up heliciform water pipe 6 in the air heating box 5, water pipe 6 is linked together with steam injection boiler's inlet tube, a steam injection boiler intake pipe of installing air-blower 7 is being connected to air heating box 5's bottom, this intake pipe is linked together with steam injection boiler's air door 8.

The utility model discloses in utilizing the high temperature flue gas that steam injection boiler produced to get into pre-heater box 1, through three-dimensional rib pipe 2 heating outside air, because three-dimensional rib pipe 2 heat absorption efficiency is high, the outside air that is heated passes through in preheater tube 4 gets into air heating box 5, further heats steam injection boiler's intaking, the outside air that is heated simultaneously gets into steam injection boiler 9 and participates in with the burning, make like this that the heat energy that contains in the high temperature flue gas that steam injection boiler produced obtain abundant utilization, energy loss has been reduced.
