Abstract
The utility model relates to an internally heating type PTC petroleum pipeline heating apparatus. The utility model is characterized in that a positive temperature coefficient resistor (PTC) is adopted as a heating element; a plurality of heating rods are composed of the heating element; the heating rods are inserted into pipelines welded by seamless steel pipes to heat petroleum flowing through the utility model. The utility model has the automatic temperature control of the PTC and has the advantages of no naked flame, high heat and electricity conversion efficiency, automatic power regulation following flow, high bearing pressure, easy aging PTC heating element replacement, long service life, electricity saving, etc. The utility model is allowed to bear the pressure of 5MPa.
Description
The utility model relates to a kind of internal heat type positive temperature coefficient resistor (PTC) petroleum pipeline heater, and it can bear 5Mpa pressure, and can change aging PTC element easily.
In the pipeline heater of oil, three types of electric heaters are arranged at present.The one, far-infrared heater, the 2nd, electromagnetic induction heater, the 3rd, external-heat ptc heater.The first two plants heater, and to exist the heat efficiency low, the frequent or not high shortcoming of temperature rise of fault, and existing external-heat ptc heater be with the PTC component affixing on thick 3 millimeters casings, bear pressure and be no more than 1.5Mpa, and be difficult to change aging PTC element.
The purpose of this utility model provides a kind of internal heat type ptc heater, and the heating element of this heater (PTC) itself can be temperature automatically controlled, need not control by circuit, the flames of anger, electric conversion efficiency is more than 95%, and complete machine bears pressure and reach 5Mpa, is easy to change aging PTC heating element.
The purpose of this utility model is achieved in that heater is the PTC heating rod by some, the pipeline that seamless steel pipe is welded into, heat-insulation layer, outer container and electric cabinet are formed, adopting positive temperature coefficient resistor PTC is heating element, and plant element thus and form heating rod (1), insert in the pipeline in this heater, heating rod (1) interlaces buckle closure together relatively by a pair of channel-section steel (2), PTC sheet (3) sticks on the channel-section steel inner surface with the conduction high-temp glue respectively, between two PTC, accompany a lead (4) and spring (5), the shell channel-section steel is an electrode, lead is another electrode, has 220 volts of voltages on this two electrode.
Two seamless steel pipes are made transverse tube (6) and some seamless pipe steel pipes to be made straight tube (7) and welds together, in every straight tube, be welded with 1-2 root flat tube, the flat tube inside dimension just in time allows to insert heating rod, liquid is unidirectional from inlet flange (8) each straight tube of flowing through in regular turn, flows out from outlet(discharge) flange (9) at last.The utlity model has following advantage:
The PTC heating rod inserts in the pipeline, constitutes inner heating.When petroleum streams by the road the time, the heat that heating rod produces is heated up outlet crude oil by fluid removal.Because pipeline is to be welded with the certain thickness seamless steel pipe, so can bear 5Mpa pressure.Because the PTC heating rod is to insert in the flat tube of pipeline of this heater, does not directly contact with oil, so can change the PTC heating rod that has worn out easily.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the PTC heating rod
Fig. 2 is a PTC heating rod profile
Fig. 3 is a pipeline of the present utility model
Fig. 4 is 2 row and 3 comb road examples
Fig. 5 is outer container of the present utility model and electric cabinet
In example of the present utility model, heating rod is to interlace buckle closure relatively together by a pair of channel-section steel (2), and PTC sheet (3) uses the high-temperature electric conduction glue respectively on the channel-section steel inner surface.A folder lead (4) and spring (5) between two PTC.When two channel-section steels compress, two channel-section steels are welded together, form a flat heating rod.The heating rod shell is connected two electrodes of PTC with central conductor, pass to 220 volts and exchange the PTC work that can make in the heating rod, produces the temperature near the PTC Curie point.
The quantity of heating rod and PTC depends on the gross power P that whole heater is required

0.86-thousand card/hour
Pipeline of the present utility model is welded by three kinds of seamless steel pipes: transverse tube (6), straight tube (7) and flat tube (9).Be welded with many straight tubes between two transverse tubes, in pipeline, flow in regular turn with unidirectional to guarantee fluid.Be welded with 1-2 root flat tube (9) in every straight tube, the inside dimension of flat tube just in time can be inserted heating rod.Heating rod heats oil by flat tube, and heating rod does not directly contact with oil.When oil when suction flange (8) flows into, the every heating rod of flowing through successively by cold heating gradually, is exported from outlet(discharge) flange (9).
When the designing high-power heater, required straight tube increases, and elongated being not easy to of complete machine carried.At this moment, can adopt the above combination of 2 rows, add a pipe (11) between two rows and be communicated with.
Pipeline outsourcing one deck thermal insulating warm-keeping layer of the present utility model (15), heat-insulation layer are outward outer containers.The structure of outer container can rainproof and dust storm.Outer container divides two partly: main tank (12) and top cover (13) are folded down lid and can change heating rod in the pipeline easily.
Outlet(discharge) flange of the present utility model (9) locates to be equipped with a bimetal leaf temperature switch (14) when the output oil temperature is higher than set point, and this switch cuts off A.C. contactor line bag power supply, stops the complete machine power supply, and the oil temperature descends.When oily temperature drop arrives a certain set point, the temperature switch closure, heater is reworked, and plays superheat protecting function.Produce the overheated just accidental a few cases that occurs,, be enough to guarantee that used control apparatus element has long useful life so the automatically controlled time of the present utility model seldom.All electric equipment is contained in the chest (16).
