The utility model adopts the above structure for the oil gas field heat exchanger, through setting up arc buffering section, can cushion axial stress, avoided collapsing between body and the tube sheet because of the body shrinkage causes.
Description
Technical Field
The utility model relates to an energy-concerving and environment-protective technique especially relates to a heat exchanger for oil gas field.
Background
A large amount of associated gas is generated in the process of oil field exploitation, the associated gas is mainly methane, ethane and propane, the traditional oil field exploitation directly discharges the associated gas into the atmosphere, so that energy waste is caused, the local ecological environment is damaged, and then a part of the oil field associated gas of people is used in a boiler, but the boiler is easy to scale due to long-term combustion, so that the heat utilization efficiency is low; the other part is used for the heat exchanger, and when the heat exchanger is in heat exchange, the temperature of the pipe body welded on the fixed pipe plate is changed in real time, so that the pipe body has temperature stress, when the temperature of the pipe body is reduced, the pipe plate is pulled by cold contraction of the pipe body, and the pipe body is separated from the pipe plate in serious conditions.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a heat exchanger for oil gas field through setting up arc buffering section, can cushion axial stress, has avoided collapsing between body and the tube sheet because of the body shrinkage causes.
In order to achieve the above object, the utility model provides a heat exchanger for oil gas field, which comprises a housin, the inside both ends of casing all are fixed with the tube sheet, two the vertical welding has the tube bank between the tube sheet, the tube bank includes an at least body, the body includes horizontal segment and arc buffer segment, the both ends of arc buffer segment all with the one end of horizontal segment is connected, the other end of horizontal segment with the tube sheet welding.
Preferably, baffles are arranged between the two tube plates in a staggered manner inside the shell, a tail gas inlet and a tail gas outlet are formed in the shell between the two tube plates, the tail gas inlet and the tail gas outlet are respectively located on the upper side and the lower side of the shell, and the tail gas inlet is communicated with an exhaust port of the gas generator set.
Preferably, a cold water inlet and a cold water outlet are formed in two ends of the shell, and the cold water inlet, the tube bundle and the cold water outlet are communicated in sequence.
Preferably, the tail gas inlet is arranged at one end of the shell close to the cold water outlet, and the tail gas outlet is arranged at one end of the shell close to the cold water inlet.
Preferably, the central angle of the arc-shaped buffer section is 60 degrees.
Preferably, the arc buffer section and the horizontal section are integrally formed.
Therefore, the utility model discloses an adopt heat exchanger for oil gas field of above-mentioned structure, through setting up arc buffering section, can cushion axial stress, avoided collapsing between body and the tube sheet because of the body shrinkage causes.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
Drawings

Wherein: 1. a cold water inlet; 2. a tail gas outlet; 3. a housing; 4. a horizontal segment; 5. an arc-shaped buffer section; 6. a baffle plate; 7. a cold water outlet; 8. a tail gas inlet; 9. a tube sheet.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
FIG. 1 is a schematic structural diagram of a heat exchanger for oil and gas fields according to an embodiment of the present invention, as shown in FIG. 1, the structure of the present invention includes a housing 3, tube plates 9 are fixed at both ends inside the housing 3, a tube bundle is vertically welded between the two tube plates 9, the tube bundle includes at least one tube body, the tube body includes a horizontal section 4 and an arc buffer section 5, the arc buffer section 5 and the horizontal section 4 are integrally formed, both ends of the arc buffer section 5 are connected to one end of the horizontal section 4, the other end of the horizontal section 4 is welded to the tube plates 9, and a central angle of the arc buffer section 5 is 60 degrees, when a temperature of the tube body changes, a majority of an axial stress acts on the arc buffer section 5, and a deformation of the arc buffer section 5 (a temperature of the tube body increases, an arc buffer section 5 stretches, a radian decreases, a temperature of the tube body decreases, the arc buffer section, thereby reducing the axial stress at the two ends of the tube body and avoiding the cracking between the tube body and the tube plate 9 caused by the frequent expansion and contraction of the tube body.
Baffle 6 is arranged inside the shell 3 between the two tube plates 9 in a staggered manner, a tail gas inlet 8 and a tail gas outlet 2 are formed in the shell 3 between the two tube plates 9, the tail gas inlet 8 and the tail gas outlet 2 are respectively positioned at the upper side and the lower side of the shell 3, the tail gas inlet 8 is communicated with an exhaust port of the gas generator set, a cold water inlet 1 and a cold water outlet 7 are formed in two ends of the shell 3, the cold water inlet 1, the tube bundle and the cold water outlet 7 are sequentially communicated, the tail gas inlet 8 is formed in one end, close to the cold water outlet 7, of the shell 3, the tail gas outlet 2 is formed in one end, close to the cold water inlet 1, namely, the flowing direction of.
Therefore, the utility model discloses an adopt heat exchanger for oil gas field of above-mentioned structure, through setting up arc buffering section, can cushion axial stress, avoided collapsing between body and the tube sheet because of the body shrinkage causes.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
