Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provide a kind of without conduction oil, can Fast Heating and the low profile thermal radiation electric heating furnace of temperature stabilization.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of low profile thermal radiation electric heating furnace, comprise coiled pipe, described coiled pipe has cavity, described cavity comprises the first cavity towards the opposite and the second cavity, all heated quarty tube is provided with in described first cavity and the second cavity, the heated quarty tube be arranged in the first cavity is connected in parallel on same circuit, and the heated quarty tube be arranged in the second cavity is connected in parallel on same circuit.
As preferred technical scheme: also comprise and to be connected with described heated quarty tube and to control the control device of each described heated quarty tube work.
As preferred technical scheme: described coiled pipe arc section place is provided with thermometer
As preferred technical scheme: the shape of described heated quarty tube is consistent with the shape of described cavity.
As preferred technical scheme: the gap between described heated quarty tube and described coiled pipe with 3 ~ 5cm
The beneficial effect that the utility model has:
When material (liquid) flows in coiled pipe, the heated quarty tube connecing electricity launches low frequency infrared light, with radiant heat, coiled pipe tube wall is heated, tube wall is by convection heat transfer' heat-transfer by convection during Flow of Goods and Materials by heating material, and spaced heated quarty tube, can according to temperature of charge in pipe, open at any time or close wherein certain or certain several heated quarty tube, avoid temperature of charge too low or too high, can flexible modulation temperature of charge, temperature of charge is stablized.
Whole apparatus structure is simple, temperature can be controlled, in stable, that height is a very little scope, to control accurately, save power consumption.
Accompanying drawing explanation

Fig. 2 is the structural representation of Fig. 1 coiled pipe;
Fig. 3 is the structural representation of heated quarty tube in Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
Shown in composition graphs 1, Fig. 2 and Fig. 3, a kind of low profile thermal radiation electric heating furnace, comprise coiled pipe 1, control device 3, coiled pipe 1 has cavity, cavity comprises the first cavity 11 and the second cavity 12 towards the opposite, and cavity is formed by the shape of coiled pipe 1 itself.All be provided with heated quarty tube 2 in first cavity 11 and the second cavity 12, the heated quarty tube 2 be arranged in the first cavity 11 is connected in parallel on same circuit, and the heated quarty tube 2 be arranged in the second cavity 12 is connected in parallel on same circuit.
Heated quarty tube 2 is all connected with control device 3 and the control of controlled device 3, and control device 3 can control separately opening or closing of certain heated quarty tube 2.
The shape of heated quarty tube 2 is consistent with the shape of cavity, and therefore in heated quarty tube 2, each position is equal with the distance of coiled pipe 1 tube wall, makes heating-up temperature also substantially the same, can ensure like this logistics homogeneous heating in coiled pipe 1.
Have the gap of 3 ~ 5cm between heated quarty tube 2 and coiled pipe 1, gap is not easily too small or excessive: excesssive gap, and heating is slow, and temperature is on the low side, wastes power; Gap is too small, heats too fast, not easily regulation and control.
Coiled pipe 1 arc section place is provided with thermometer 4, thermometer 4 is for detecting the temperature of logistics in coiled pipe 1, when certain thermometer 4 detects that temperature is too low herein, utilize control device 3 to regulate and the heated quarty tube 3 in the parallel corresponding cavity of this thermometer 4, make it start working or add high-power; In like manner, when certain thermometer 4 detects that temperature is too high herein, regulate and the heated quarty tube 3 in the parallel corresponding cavity of this thermometer 4, close or reduce power.
Embodiment 1: have a kind of paraffin oil to carry out deep hydrogenation reaction, this oil temperature is 280 DEG C, flow is 600kg/h, needs to be heated to 330 DEG C, calculates by the mechanical equivalent of heat, the electric energy power of Need Hierarchy Theory is 18 kilowatts, for considering heat transfer efficiency, the needs of lagging casing heat radiation and adjustment temperature, adopt 3 kilowatts of heated quarty tube 2, amount to 12,36 kilowatts.Heated quarty tube 2 is divided into four groups, often organizes 3 and is connected in parallel, can regulate out arbitrarily 1 to 4 group.In actual motion, normal condition opens 3 groups, and paraffin oil is heated to 332-335 DEG C.
Embodiment 2: have an ammonia cracking reaction to produce the test of hydrogen and nitrogen, reaction temperature is 800 DEG C, and ammonia flow is 0.5kg/h (0.66NM
3/ h), need electrical power to be 0.8 kilowatt by ammonia cracking, in coiled pipe 1, loading catalyst leads to ammonia, considers heat radiation and regulates, and configuration heated quarty tube 2, often props up power 1.5 kilowatts, can by heating temperatures in coiled pipe 1 to 820 DEG C after operation, final hydrogen producing 1NM
3/ h.
