Abstract
The utility model discloses a crude oil and natural gas heating furnace flue gas waste heat ordinary pressure recovery unit, including being used for carrying out the heating mechanism of heating to crude oil / natural gas, heating mechanism includes the heat transfer room that is full of heating medium and fixes at the compound coil pipe of the indoor conduct of heat transfer to crude oil / natural gas heating unit, the inside cavity of coil pipe, both ends connection crude oil / natural gas advances, the exit tube, and crude oil / natural gas advances, the exit tube passes heat transfer room lateral wall and external intercommunication, still include waste heat recovery mechanism, waste heat recovery mechanism is the heat exchanger, and its heat absorbing end sets up together with external flue passageway, and heat releasing end sets up in the heat transferring medium of heat transfer room. This technical scheme with the chimney flue with the heating mechanism be connected, retrieve the high temperature heat in the flue, further increased energy utilization and rateed.
Description
Technical field
This utility model belongs to crude oil/heated by natural gas technical equipment field, especially relates to a kind of crude oil and heated by natural gas furnace flue gas exhaust heat atmospheric recovering device.
Background technology
In the production of exploitation oil gas, crude oil, gas heating furnace namely to oil field to the blend heated a kind of common equipment of natural gas, oil and its two kinds, after oil gas heating-furnace behaves, flue gas is through combustor and convection cell, eventually pass chimney to discharge, the waste heat of flue gas can reach about 180 DEG C, and heat loss is the highest, wastes resource pollution environment.
Utility model content
In order to during making up above-mentioned crude oil/heated by natural gas, heat exchanger tube is easily revealed, the defect of high-temperature flue gas heat waste, the utility model proposes a kind of crude oil and heated by natural gas furnace flue gas exhaust heat atmospheric recovering device.
Its technical scheme is: includes that the heating arrangements for heating crude oil/natural gas, described heating arrangements include being full of and adds the Heat Room of thermal medium and be fixed in Heat Room as the compound coil pipe to crude oil/heated by natural gas unit；Coil pipe inner hollow, two ends connect crude oil/natural gas and are in communication with the outside through Heat Room sidewall into and out of pipe into and out of pipe, crude oil/natural gas；Also including that waste heat recovering mechanism, described waste heat recovering mechanism are heat exchanger, together with its heat absorbing end is arranged with extraneous flue passage, release end of heat is arranged in the heat transferring medium of Heat Room.Chimney air flue is connected by the technical program with heating arrangements, reclaims the heat of high temperature in flue, further increases energy utilization rate.
Being also associated with multiple heat transmission fin outside coil pipe, heat transmission fin mutual spacing is from no less than 30cm.In the technical program, heat transmission fin further increases the heating surface area of coil pipe, and heat transmission fin typically uses the heat-conducting metal such as material such as copper, aluminum simultaneously, and heat transfer efficiency is high, and firing rate is fast.
Described composite heating coil pipe outer wall includes the stainless steel layer of inside and is wrapped in the carbon steel layer outside stainless steel layer.In the technical program, use stainless steel layer corrosion-resistant, prevent the corrosion of crude oil/natural gas, outer wrap carbon steel layer, increase its mechanical strength.
The release end of heat of waste heat recovering mechanism and heat transmission fin are secured together in integrative-structure.In the technical program, the release end of heat of waste heat recovering mechanism is connected in integrative-structure with heat transmission fin, adds heat conduction efficiency, improves heat utilization ratio, even if heat passes in compound coil pipe the most in time, it is also possible to pass to heat transferring medium saves as compound coil pipe subsequent heat.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described further.
In conjunction with Fig. 1, the structural representation of embodiment of the present utility model.
This novel a kind of embodiment, a kind of crude oil and heated by natural gas furnace flue gas exhaust heat atmospheric recovering device, including the heating arrangements 1 for heating crude oil/natural gas, described heating arrangements includes being full of and adds the Heat Room of thermal medium and be fixed in Heat Room as the compound coil pipe 2 to crude oil/heated by natural gas unit；Coil pipe inner hollow, two ends connect crude oil/natural gas inlet pipe 21, go out pipe 22, and crude oil/natural gas is in communication with the outside into and out of pipe through Heat Room sidewall；Also including that waste heat recovering mechanism 3, described waste heat recovering mechanism are heat exchanger, together with its heat absorbing end is arranged with extraneous flue passage 4, release end of heat is arranged in the heat transferring medium of Heat Room.
The another kind of embodiment of compound coil pipe in accompanying drawing 1, is also associated with multiple heat transmission fin 23 outside coil pipe, and heat transmission fin mutual spacing is from no less than 30cm.Using heat conduction coil pipe to increase the heating surface area of compound coil pipe, heat transmission fin mutual distance prevents it the most intensive to be reduced by rate simultaneously.
The pipeline of compound coil pipe can be made into double-deck rhythm to increase corrosion resistance and mechanical strength, and described compound coil pipe outer wall includes the stainless steel layer of inside and is wrapped in the carbon steel layer outside stainless steel layer.
In order to improve the heat exchange efficiency of waste heat recovering mechanism further, the release end of heat of waste heat recovering mechanism and heat absorbing fins are secured together in integrative-structure.This structure ensures that release end of heat heat can be quickly transferred on compound coil pipe or heat transferring medium in time.
In sum, whole intensions the most of the present utility model: hereafter, all have within by utility model subject spirit any amendment made, replacement until improving the projects such as upgrading, within being included in protection domain of the present utility model.
