Description
Technical field
The utility model relates to dynamo-electric heating technique, its equipment has mobility, is mainly used in the oil field, the freezing of solution instrument in the drillng operation, equipment, pipeline, stifled problem, also is applicable to the heating of metallurgy, chemical industry, pharmacy, food service industry and no suspended substance gas, liquid; Can promote and be used for explosion-proof, aseptic production scene.
Background technology
Petroleum industry, the drilling well in winter and repair and the work production process in, because of temperature is lower than below 0 ℃, often occur that equipment (petroleum pipeline, gas, water pipeline, well head gate valve, bent sub etc.) freezes, stifled phenomenon and rig tool (pipe wrench, elevator etc.) and drilling tool freezes phenomenon and the well head petroleum pipeline freezes stifled problem, influences normal safety in production process.
Solve at present freezing of occurring in the drillng operation production winter, stifled problem method commonly used and be with steam scald and blowtorch roasting.The method that adopts steam to scald must be equipped with boiler car.In the time of in this way, the fog of steam reduces visibility, influences normal production operation, causes security incident easily, and the expense height.Use the blowtorch hot-spot to be easy to it is burnt out, cause easily and cause enormous economic loss by fire, and naked light is forbidden to employ in the explicit stipulation well site in the relevant operating regulation.Therefore overpressure resistant and explosion-proof mobile gas, the liquid firing equipment meets the tendency and design generation.
The utility model content
Task of the present utility model is to provide a kind of scene easy to use, safe, economic overpressure resistant and explosion-proof mobile gas-liquid heating equipment at the problem of prior art existence.
This novel task is realized by following technical scheme: a kind of overpressure resistant and explosion-proof mobile gas-liquid heating equipment, comprise the electric-heating assembly of forming by many electric heating tubes, automatic electric controller, automatic temperature control, also have dolly, explosion-proof electric heating apparatus is installed on the dolly: many electric heating tubes of described electric-heating assembly are assembled in the pressure vessel and boundling is fixed in the flange end of pressure vessel; A plurality of deflection plates along the upper and lower one by one dislocation of pressure vessel axis be fixed on the pressure vessel inwall, the import of heat medium is located near the flange end of this container, the outlet of heat medium is located near this vessel head end, and this container is provided with pressure relief safety valve, and automatic electric controller and temperature are controlled device automatically and be installed on the dolly.
Above-mentioned pressure vessel is outside equipped with adiabator layer, is covered with metal shell on the adiabator layer, and insulation material and metal shell are formed the insulation casing.
Above-mentioned electric heating tube is the explosion-proof type electric heating tube.
The pressure vessel of above-mentioned insulation casing and explosion-proof electric-heating assembly one and explosion-proof electrical autocontrol cabinet, explosion-proof electronic temperature controller, connecting line etc. are installed on the dolly.
This novel employing Electric heating replaces existing Steam Heating or blowtorch mode of heating, on the one hand, existing management expectancy in view of the oil field, must reduce operating cost from each link, and can't stand the Steam Heating mode of existing high cost expenditure and thermo oil boiler Steam Heating pollution and destruction environment; On the other hand, because the electric power facility in oil field can possess the external condition that adopts the electric heater mode in the electricity consumption easily of each scene.
This novel electric heating equipment is a kind of electric energy directly to be converted to heat energy, and gas, liquid medium to the need heating heat as air.After flow media enters the pressure vessel heating, in container, make the rotation wave through the deflection plate left hand material and flow, carry out sufficient heat exchange with the surface of electric heating tube, make medium obtain heating, thereby obtain the high-temperature medium of technological requirement in outlet.Because medium is turbulence state, contacts with the electric heating tube surface in container.Therefore this heater is than the heat exchanger effectiveness height of existing general electric heater unit.
This novel automatic temperature control is regulated the electric heater power output automatically according to the temperature sensor signal that is arranged on the heat medium outlet, makes the medium temperature of outlet reach technological requirement; When thermal medium is lower than technological requirement; can connect power supply automatically, when the heater element overtemperature, overtemperature protection system cuts off heating power supply immediately; avoid adding the thermal material overtemperature and cause coking, rotten, charing, cause heater element to burn out when serious, effectively prolong electric heater service life.
Compared with prior art, this novel beneficial effect is:
1, have mobility, operation field is easy to use.
2, compare with Steam Heating, the present invention is energy-conservation, economy, environmental protection
With the steam oil burning boiler is example, the one, and boiler is necessary continuous service between whole turn(a)round, and this novel electric heating equipment then can not move during whole continuously, only uses the period to move in the needs heating; The 2nd, under little firer's condition, (promptly only keep the basic operational situation of boiler with boiler, and be the big fire operating mode during externally normal vapour work), one day burning 1000L (No. 0) diesel oil, in 4.8 yuan/L diesel oil, then per hour the fuel cost of boiler is 200 yuan, and this novel electric heating equipment, with 18K watt of heating tube power, air compressor machine power 18.5 kilowatt meters, then per hour electricity consumption 28.5 is spent, by 1 yuan/degree electricity, then this novel per hour electric cost is 28.5 yuan, only is 1/7 of boiler oil cost.Therefore, this novel not only saving but also environmental protection has been saved cost of use, has reduced production cost, and has not produced any waste gas waste water, and environment for use is pure and fresh clean.
3, heating tank adopts pressure vessel and corresponding blasting protection facilities, and promptly explosion-proof electric-heating assembly adopts the EXdIIBT4 explosive-proof grade, and explosion-proof automatic electric controller adopts the ExdIIBT6 explosive-proof grade.Magnetic valve, electro connecting pressure gauge etc. all adopt explosion-proof type in addition, and therefore this novel security has in use had practical assurance.
4, heat medium time of staying in heating tank long, and form turbulent flow on heating tube surface and strengthened temperature efficient, thereby the heat transfer efficiency height.The external heat-insulation layer that adds of heating tank, this just makes this electric heater unit have the advantage of conserver power source, thereby than the corresponding reduction use cost of similar products.
5, reach service life more than 3 years: because its heater is special alloy material, so under the impact of high-pressure medium stream, it is all better than the mechanical performance and the intensity of any heater, can satisfy long-time continuous and constantly add heat request.
6, this novel problem such as stifled of freezing that can solve the thawing of present drilling well, light maintenance, heavy repair task scene, de-plugging and well head preferably to the gathering station petroleum pipeline, eliminate and use the blowtorch solution to freeze disaster hidden-trouble stifled and that frozen problem exists, avoid the generation of fire incident, for realizing that winter, safety in production provided material base.Simultaneously this kind mini-plant can also be applied to the special process occasion of industry such as northern motor vehicle repair and metallurgy, chemical industry, pharmacy, food service industry.
7, this novel low-temperature zone that is provided with can solve the heating problem that the aboveground worker in oil field has a rest, sleeps.
