An electric heating tube is arranged in the mouse cage tube and is connected with an automatic control circuit for temperature through a temperature sensing probe to realize automatic temperature control, and the temperature sensing probe is arranged in the heating chamber. The heater has the advantages of uniform heating, stable temperature heating, high heat exchange rate, energy saving and no pollution, and is especially suitable for being used by the design with large power and flow rate. The heater is an ideal renewal product of an oil-burning boiler and a single electric heater.
Description
The utility model relates to the raw-material warming-up device of fluid of oil, chemical industry.Particularly a kind of multistage warm electric heater for fluid that progressively increases.
At present, the heating team in each oil field, chemical plant adopts oil burning boiler mostly.Because flammable liquid need heat before entering boiler, heat and make its atomizing, to reach the best combustion effect, there is following drawback in the pipeline heating of the existing oil burning boiler modes that adopt steam boilers, electric heater heating flammable liquid more:
1, adopts the mode of heating of Steam Heating flammable liquid; flammable liquid is difficult to reach the temperature requirements value; through regular meeting produce that fuel combustion efficiency is poor, energy consumption big, contaminated environment, the easy coking of burner hearth, and there is very big unsafe factor in steam boiler in running.
2, adopt the mode of heating of oil burning boiler electric heater, mostly be single-stage temperature control and single heating chamber, intermittent duty has promptly appearred in heat exchanging process and between " heating " and " stopping ", the fuel oils that cause not reaching in a large number the temperature requirements value are sneaked into the stove internal combustion, cause that atomizing is poor, the interior coking of stove, contaminated environment.
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, particularly single heating chamber, the single temperature control of the existence of oil burning boiler electric heater mode of heating, be interrupted heating, the incomplete problem of oil inflame, the multistage warm electric heater for fluid that progressively increases of a kind of a plurality of heating clamber, multistage temperature control is provided.
The technical solution of the utility model is:
A kind of multistage warm electric heater for fluid that progressively increases, form by heating clamber 19, electric heating tube 11 and automatic temperature control circuit, it is characterized in that: be connected as a single entity by straight pipe 23 parallel arranged by a plurality of heating clambers 19, be connected oil-in pipe nipple 21 and oil-out pipe nipple 24 at preceding heating clamber 19 with back heating clamber 19 respectively, and by flange with the turnover oil pipe be connected, mouse cage pipe 17 is installed in inside at heating clamber 19, be fixedly clamped in heating clamber 19 by porous plate 15, fin 16 is equipped with in the outside of mouse cage pipe 17, inside is fitted with electric heating tube 11, and fixing by fixed disk 12.
The technical scheme of this multistage warm electric heater for fluid that progressively increases further is improved to, and heat insulation rock wool 13 is housed between electric heating tube fixed disk 12 and porous plate 15, between electric heating tube 11 and mouse cage pipe 17 thermal insulating disc 14 is housed.
In the body of each heating clamber 19, be equipped with crude oil temperature-sensing probe 22 respectively be arranged on casing 25 above instrument board on temperature controller 3 be connected.
Multistagely progressively increase warm electric heater for fluid compared with the prior art according to what such scheme provided, have technology advanced person, homogeneous heating, temperature stabilization, firing rate is fast, rate of heat exchange is high, energy-conservation, consumption reduction, safety coefficient are big, operation, easy to maintenance, of many uses, high-power, the big flow design of particularly suitable is used.
Elaborate below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
As shown in Figure 1, the 1st, ammeter, the 2nd, run indicator, the 3rd, temperature controller, the 4th, power supply indication, the 5th, start button, the 6th, voltmeter, the 7th, boiler temperature control instrument, the 8th, work indication, the 9th, stop button, the 10th, binding post, the 11st, electrothermal tube, the 12nd, electrothermal tube fixed disk, the 13rd, heat insulation rock wool, the 14th, electrothermal tube thermal insulating disc, the 15th, porous plate, the 16th, fin, 17 mouse cage pipes, 19 heating clambers, the 20th, carriage, the 21st, oil-in pipe nipple, the 22nd, crude oil temperature-sensing probe, the 23rd, straight pipe, the 24th, oil-out end joint, the 25th, casing.
The utility model is made up of heating clamber part, heating part and automatic control section.At heating clamber partly is to be connected as a single entity by straight pipe 23 parallel arranged by a plurality of heating clambers 19, is connected oil-in pipe nipple 21 and oil-out pipe nipple 24 at preceding heating clamber 19 with back heating clamber 19 respectively, and is connected with the turnover oil pipe by flange.Mouse cage pipe 17 is installed in inside at heating clamber 19, is fixedly clamped in heating clamber 19 by porous plate 15, and fin 16 is equipped with in the outside of mouse cage pipe 17, and inside is fitted with electric heating tube 11, and fixing by fixed disk 12.Heat insulation rock wool 13 is housed between electric heating tube fixed disk 12 and porous plate 15, between electric heating tube 11 and mouse cage pipe 17, thermal insulating disc 14 is housed.
The ectosome of each heating clamber 19 be equipped with temperature-sensing probe 22 respectively be arranged on casing 25 above instrument board on temperature controller 3 be connected.Ectosome at back heating clamber 19 is equipped with furnace temperature probe 26, is connected with boiler temperature control instrument 7.
In conjunction with Fig. 2, binding post 10 usefulness leads are connected on the underfooting static contact of contactor C1, C2, C3, C4 reliably, and temperature-sensing probe 22 is connected with temperature controller 3 usefulness holding wires respectively, and furnace temperature probe 26 links to each other with boiler temperature control instrument 7.Power supply lead wire is connected fuse RD1, RD2 last (two-way power supply situation) reliably, automatic switch ZK1, ZK2 close, press start button 5, AQ intermediate relay ZJ adhesive work, boiler temperature control instrument 7 send electricity work through relay ZJ, feedback signal to furnace temperature probe 26 is reacted, control boiler temperature control instrument work or stop.Temperature controller 3 is reacted to the feedback signal of temperature-sensing probe 22 respectively, the work of control time relay SJ1, SJ2, SJ3, SJ4 or stop.By the delay protection function of the time relay, contactor C1, C2, C3, C4 are carried out the control of classification adhesive and disjunction, thereby reach heater heating and the automatic control process that stops to heat.Press stop button 9 (AT), the control loop power supply is cut off in the intermediate relay ZJ outage, and heating work stops.
On the mouse cage pipe 17 in the heating clamber 19 fin 16 is housed, the heat radiation that electric heating tube 11 produces is passed to and is heated liquid to mouse cage pipe 26 and fin 16, owing to electric heating tube 11 does not directly contact with being heated liquid, so electric heating tube 11 can coking.Because each heating clamber is separate component use capable of being combined again, under the situation that does not influence other heating clamber work, fix a breakdown, therefore reached energy-conservation, efficient, safety anti-explosive, antipollution purpose.
