Description

The combined type heat pipe Crude oil heater

The utility model belongs to the rock gas combined type heat pipe Crude oil heater that a kind of heating crude oil is used.

The horizontal water jacket furnace of present existing oil well heating crude oil, this stove need have special natural gas line and water pipeline, it makes by gas-firing, and water temperature raises in the body of heater, by water temperature crude oil pipeline is heated again, it is low that it has the thermal efficiency, design thermal efficiency only is 65%, and the thermal efficiency has only about 50% during practical application, heat insulation effect is poor, shortcomings such as explosion risk are arranged,, occur a kind of vertical heat pipe well head crude oil electric heater in recent years in order to address the above problem, but its power can only not satisfy the needs of barreler heating crude oil below 100KW.

At the problems referred to above, the purpose of this utility model is to overcome deficiency of the prior art, is the power big (more than the 100KW) of thermal source with the rock gas and provide a kind of, quick heating, thermal efficiency height (84%), long combined type heat pipe Crude oil heater of life-span.

The utility model is achieved in that it mainly is made of insulation outer cylinder body, heat exchange container cylindrical shell, combined type heat pipe system, sledge car base; Venting is housed in insulation on the outer cylinder body, its underpart be equipped with external flue with it in the top be communicated with inner flue, in heat exchange container cylindrical shell bottom crude oil import, blowdown valve are housed, be provided with crude exports, pressure gauge, safety valve, outlet pipe at an upper portion thereof; The combined type heat pipe system connects the many Composite thermal energy generators that curved steel tube place forms by totally enclosed sleeve body inwall upper and lower end place, bottom, connect a vertical heat energy transmission sleeve pipe on its top, and be communicated with the gas distributor that eliminates stress in the upper end of heat energy transmission sleeve pipe, the composite heat exchanger that one to multiple circle Spiral Steel Pipe that is communicated with it or one to multiple circle squirrel-cage steel pipe are formed is communicated with Composite thermal energy generator and composite heat exchanger with reflow pipe.During work, crude oil is pressed in crude oil import enters the heat exchange container cylindrical shell from the pumping unit band, the combined type heat pipe system flows through, the crude oil that makes 15 ℃-20 ℃ is under the composite heat exchanger effect, temperature is elevated to 60 ℃ of setting temperatures-90 ℃ (can decide according to need) fast, heated then crude oil when the oil temperature keeps set temperature value, enters pipe network from crude exports.

The utility model compared with prior art has thermal efficiency height, materials are few, cost is low, the life-span is long, can realize automatic control, and is safe and reliable; Its key component is that the combined type heat pipe system is a vertical unit, compact structure, its Composite thermal energy generator, heat energy transmission sleeve pipe, the gas distributor that eliminates stress, composite heat exchanger, reflow pipe is installed in from bottom to top and forms one in the heat exchange container cylindrical shell to the crude oil optimum cycle system that heats; The characteristics of heat-pipe technology are quick heatings, conduct heat fast (the same velocity of sound), so can make the crude oil set temperature value that is rapidly heated; The heat pipe design life-span is 10 years; Comparing the utility model with water jacket furnace is vertical, and volume is little, take up an area of less, economized water supply facilities, noiseless, do not pollute, no explosion risk; The energy of heating is rock gas, and flame size realizes automatic control by the crude oil temperature feedback signal in the heat exchange container cylindrical shell, reduces labor intensity.
