Description
Technical field
The utility model relates to a kind of heating furnace heat exchanger tube heat transfer coefficient determinator, is used for the mensuration of the heat transfer coefficient of oil field heating furnace coil pipe.
Background technology
Some oil field is higher because of the heavy constituent content in crude oil or the rock gas, needs to adopt heating furnace that crude oil or rock gas are heated up.Heat exchanger tube heat transfer coefficient determinator is exclusively used in the mensuration to heating furnace coil pipe heat transfer coefficient.The design of oil field heating furnace heat interchanging area, the necessary heat transfer coefficient of confirming heat exchanger tube earlier.Usually confirm heat transfer coefficient according to Theoretical Calculation and some empirical values earlier, calculate the heat transfer area of heat exchanger tube then according to heat transfer coefficient.But because block various oil property othernesses in oil field are very big, the heat interchanging area that the heat transfer coefficient of confirming through Theoretical Calculation or experience obtains is often not really accurate, often produces bigger deviation and can't satisfy the actual needs to crude oil or rock gas heating.
Summary of the invention
The purpose of the utility model provides a kind of heating furnace heat exchanger tube heat transfer coefficient determinator, can confirm the heat transfer coefficient of heating furnace heat exchanger tube through test with this device.
This heat transfer coefficient determinator comprises water tank, and water tank is provided with the filler; Electric heater and coil pipe are housed in the water tank, and the entrance point of coil pipe and endpiece extend to outside the water tank, and the entrance point of said coil pipe and endpiece all are equipped with thermometer and tensimeter, and entrance point or endpiece are equipped with flowmeter.
Said water tank is provided with blow vent.
Said water tank is provided with sewage draining exit and blowoff valve.
Said filler is provided with water valve.
Adopting this device is intermediate medium with the water in the water tank; Through electric heater water is heated, hot water is medium heating in the coil pipe, and the import and export temperature and the flow that record according to medium; Again according to the known heat transfer area and the power of electric heater, through formula calculate heat transfer coefficient.With the data that this device makes an experiment and obtains, through calculating the heat transfer coefficient of confirming the heating furnace heat exchanger tube, error is little again, and accuracy is high.Design the heat interchanging area of the reality of heating furnace heat exchanger tube with this heat transfer coefficient, more tally with the actual situation, avoid occurring the heating furnace too big problem of not enough or rich amount of exerting oneself.

Embodiment
Fig. 1 is hot stove heat exchanger tube heat transfer coefficient assay device structures synoptic diagram.Like Fig. 1, in water tank 13, add entry 12 from filler 6, simultaneously measured medium (crude oil or rock gas) is got into coil pipe 8 from import 2, flow out from media outlet 1.Water 12 in the water tank by electric heater 15 heating, with treat measured medium in heat transferred coil pipe 8, makes medium heat temperature raising after water is heated as intermediate medium.
From radiator thermometer 5 read the temperature data of water; Record the out temperature of measured medium respectively through inlet temperature meter 10, outlet temperature meter 3, inlet pressure gauge 11 and delivery gauge 4, rate-of flow meter 9; Inlet and outlet pressure and flow according to these parameters that records, calculate with formula K=Q/ (A* Δ Tm); (Q is a thermal power in the formula, can try to achieve according to electrical bar power and efficient to obtain the heat transfer coefficient of test unit.A is the actual heat interchanging area of coil pipe, can survey, and Δ Tm is a log-mean temperature difference).The K value that calculates is the heat transfer coefficient value.
In this device, blowoff valve 14 plays the blowdown effect, and blow vent 7 and atmosphere make to keep normal pressure in the water tank 13.
