Description
1, technical field:
The utility model relates to a kind of heat interchanger, relates in particular to a kind of heating crude oil heat interchanger.
2, background technology:
In the manufacturing process of recovering the oil, owing to contain materials such as pitch, mineral tallow in the crude oil, these materials can solidify under normal temperature or low temperature, are unfavorable for the conveying of crude oil.For guaranteeing the conveying of crude oil, need crude oil is heated, make crude oil remain liquid condition.Generally be to adopt water jacket furnace now to heating crude oil, such as: fire tube examination heating water jacket stove, U type water jacket furnace or the like, they all are to rely on to increase area of dissipation, be achieved the purpose of interchange of heat, and be heat transfer medium with water, but the ratio enthalpy of water is low, and heat-transfer effect is undesirable, and saturation water specific enthalpy in the time of 99 ℃ is that 417kj/kg is 504.7kj/kg than enthalpy in the time of 120 ℃.For increasing heat output, just adopt the way that increases heat capacity, the increase equipment of trying one's best increases heat capacity and adorns water more, and general water jacket furnace need add 14 tons water, need absorb a large amount of heats when these water are heated to operating temperature, certainly will cause waste.Simultaneously, it is big to make a water jacket furnace consumptive material, and simultaneously in the course of the work, the natural gas of burning is along with the flow of crude oil is different uncontrollable, and the design maximum stream flow according to crude oil heats always, causes a large amount of waste of natural gas.
3, summary of the invention:
The purpose of this utility model is to propose a kind of simple in structure, and cost of manufacture is low, Controllable Temperature, the heating crude oil heat interchanger of energy conservation.
The purpose of this utility model is achieved in that the heating crude oil heat interchanger, comprises heat interchanger, and the medium heating furnace of heat energy is provided for heat interchanger.Heat interchanger is a cavity jar, be welded with on the inwall at an upper portion thereof at least nine roads from front to back, crooked heat exchanger tube back and forth, heat interchanger is stretched out at the heat exchanger tube two ends, is communicated with oil inlet pipe, flowline respectively.Medium heating furnace is the cavity body that is provided with water jacket layer, and its center is installed with smoke pipe, and smoke pipe bottom installing natural gas nozzle is installed temperature controller thereafter, and and natural gas air inlet pipe conducting.Be communicated with the medium steam pipe between heat interchanger and medium heating furnace, be close to installing one temperature pick up on the heat exchanger tube outer wall at heat interchanger, it is connected with the temperature controller circuit.
The utility model is simple in structure, in light weight, adopt ZGM composite chemical medium place of water to conduct heat, heat-transfer effect is better, in the crude oil transmission course, the based on crude transmission quantity is regulated heating-up temperature, energy conservation automatically, save the cost of manufacture of heat transmitter simultaneously, safety factor height, but the high-temperature gas that natural gas produces second use also, economic environmental protection.
4, description of drawings:
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is a heating crude oil heat converter structure schematic diagram.
Legend: 1, thermometer, 2, pressure meter, 3, electromagnetic valve, 4, heat exchanger tube, 5, flowline, 6, chimney, 7, smoke pipe, 8, pedestal, 9, leg, 10, temperature pick up, 11, the medium steam pipe, 12, temperature controller, 13, natural gas nozzle, 14, medium heating furnace, 15, oil inlet pipe, 16, heat interchanger, 17, detector tube.
5, the specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, the heating crude oil heat interchanger comprises heat interchanger 16, and the medium heating furnace 14 of heat energy is provided for heat interchanger 16.Heat interchanger 16 is whole laterally, inclined seat is on pedestal 8, supported by leg 9, it is a cavity jar, be welded with on the inwall at an upper portion thereof at least nine roads from front to back, crooked heat exchanger tube 4 back and forth, heat interchanger 16 is stretched out at heat exchanger tube 4 two ends, is communicated with oil inlet pipe 15, flowline 5 respectively.Medium heating furnace 14 is for being provided with the cavity body of water jacket layer, and its center is installed with smoke pipe 7, and smoke pipe 7 bottoms installing natural gas nozzle 13 is installed temperature controller 12 thereafter, and and natural gas air inlet pipe conducting.Smoke pipe 7 penetrates in the heat interchanger 16, and is divided into three roads, heat interchanger 16 in addition end to converge be a pipe again, and pass heat interchanger 16 and the chimney 6 that is erected on the pedestal 8 is communicated with.Be communicated with medium steam pipe 11 between heat interchanger 16 and medium heating furnace 14, heated medium is managed 11 thus and is fed heat interchanger 16.Be close to installing one temperature pick up 10 on heat exchanger tube 4 outer walls at heat interchanger 16, it is connected with temperature controller 12 circuit.Also be communicated with U-shaped detector tube 17 in heat interchanger 16 upper ends, be equiped with thermometer 1, pressure meter 2 and electromagnetic valve 3 on it side by side.
During use, by the ZGM composite chemical medium in the heat heat medium heating furnace 14 of natural gas burning generation, because heat interchanger 16 is for being in tilted layout, and heat conductivility according to liquid, heated MEDIA FLOW heat exchanger 16 tops, the medium that temperature is low flows back in the water jacket layer of medium heating furnace 14, continues to be heated, thermal medium remains at around the heat exchanger tube 4, strengthens the efficient of the heating crude oil in the exchange heat pipe 4.Collection by heat exchanger tube 4 ambient temperatures in 10 pairs of jars of temperature pick up, changing data signal into sends out and temperature controller 12, temperature controller 12 is regulated the natural gas flow automatically according to setting program, oil flow is big in the heat exchanger tube 4, then heat exchanger tube 4 temperature are corresponding lower, regulate the natural gas flow this moment and increase, it is big that flame becomes; Oil flow is little in the heat exchanger tube 4, and then heat exchanger tube 4 temperature are corresponding higher, and regulate the natural gas flow and reduce this moment, and flame diminishes, thereby changes the medium temperature in the medium heating furnace 14, to reach the purpose that changes Controllable Temperature in the heat interchanger 16.Monitor the parameters in the heat interchanger 16 in real time by the thermometer on the detector tube 17 1, pressure meter 2, if pressure is excessive, open electromagnetic valve 3, release pressure guarantees safety.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
