Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
According to the utility model embodiment, provide a kind of renewable core formula anti-explosion electric heater.Shown in Fig. 1-Fig. 1 b, present embodiment comprises container, be axially arranged with pyrotoxin 6 in the inside of container, cooperate at first port of container to be provided with anti-explosion terminal box 1, anti-dry temperature probe 5 and suction flange 10, cooperate at second port of container to be provided with explosion-proof temperature probe 8 of outlet and outlet(discharge) flange 9; Between the inwall and pyrotoxin 6 of container, evenly be interval with a plurality of deflection plates 7; First port cooperation at container is provided with pyrotoxin 6 flanges, and pyrotoxin 6 flanges comprise flange 3 and blind flange 2.
Particularly, anti-explosion terminal box 1 and anti-dry temperature probe 5 all by flange 3 and blind flange 2, are connected with container; Second port closed of container exports explosion-proof temperature probe 8 and is located on the outlet(discharge) flange 9.
Here, anti-explosion terminal box 1 is carried out in strict accordance with GB3836.1-2000, GB3836.2-2000 standard, the maximum pressure that the model of outlet(discharge) flange 9 is DN150, can bear is 1.0MPa, the maximum pressure that the model of suction flange 10 is DN150, can bear is 1.0MPa, and the maximum pressure that flange 3 is DN150 with the model of blind flange 2, can bear is 1.0MPa.
Further, in the above-described embodiments, container comprises that model is the seamless steel pipe 4 of DN150; The container that uses seamless steel pipe 4 to be welded, through the 10kg gas pressure test, the ne-leakage phenomenon; This container is made according to pressure vessel, can pass through the hydraulic test of 1.0Mpa pressure.But pyrotoxin 6 comprises many groups of frog-changing type electrical bars that evenly are provided with continuously.In many group renewable core formula electrical bars, every group of renewable core formula electrical bar comprises skeleton, and is evenly distributed on the heating wire on the skeleton.
When changing pyrotoxin 6, need not,, can separately pyrotoxin 6 be extracted out, easily change because the pyrotoxin of renewable core formula anti-explosion electric heater 6 separates fully, seals with medium with medium emptying in the renewable core formula anti-explosion electric heater chamber, and with low cost.
Here, heating wire comprises that model is 2080 nichrome wire, 1000 ℃ of the highest long-term serviceability temperatures; Heating wire forms through special facture, helps increasing the service life, and the surface loading of heating wire is not more than 4W/cm
2Skeleton is the inorganic insulation skeleton, and the inorganic insulation skeleton adopts inorganic insulating material, and inorganic insulating material has the advantage of high temperature resistant and fire-retardant and good insulation preformance.The heating wire of heater is installed on the skeleton of inorganic insulating material, has guaranteed the good insulation performance performance.The heating wire of heater is strict control surface load in design process, and it is worked under low-power, low temperature.Can prolong the life-span of heating wire so greatly.At the connecting portion of binding post and heating wire, all adopt welding method, the two is fused into one, guarantee each other and increase the accident of blowing because of resistance.
The renewable core formula anti-explosion electric heater of the foregoing description, it is whole that heating wire, skeleton, container and anti-explosion terminal box 1 are made into a heating, container adopts steel design, make its can shock resistance, phenomenon such as counter-bending, and can not damage total quality.Because load is a pure resistance, so the power factor (PF) height.Heating wire is to be evenly distributed on the skeleton in addition, and by the mode of conduction, radiation heat is evenly passed to tube wall, makes the evenly heating of surface of shell.The heater heater is hermetically sealed overall structure, just integral part all is immersed in the medium, and the heat that heater is produced all rejects heat in the medium.The entire length of heater is long, makes medium pass through deflection plate 7 water conservancy diversion in heater, so the medium heating fully, evenly.
During installation, renewable core formula anti-explosion electric heater can adopt horizontal installation, the outlet of renewable core formula anti-explosion electric heater upwards, pipe outlet is connected with the import of renewable core formula anti-explosion electric heater, the outlet of renewable core formula anti-explosion electric heater is connected with the import of pipeline, for the ease of maintenance, can be at renewable core formula anti-explosion electric heater import and export mounted valve; To guarantee not have the seepage flow phenomenon during installation.
During work, be by pyrotoxin 6 heat that produces, in container, form heating chamber, pyrotoxin 6(electrical bar) be the heat that sends by heating wire, through the conduction of air and the radiation of heat, heat is passed to the tube wall of shell of tank rapidly, because shell of tank is that seamless steel pipe 4 and pyrotoxin 6 are little with the tube wall gap of seamless steel pipe 4, institute is so that the very fast rising of seamless steel pipe 4 surface temperatures, and surface temperature is passed to medium.
Particularly, because the heat of pyrotoxin 6 spreads out of continuously, make medium temperature lifting in the heating chamber; Medium flows into from import, through the heating chamber heating, after forcing water conservancy diversion in the heating chamber, flows out a process from outlet, makes medium reach temperature required.That this renewable core formula anti-explosion electric heater has is simple in structure, solid, bending strength is high, and heating evenly, the heat efficiency is high, and reliable operation, long service life such as install, maintenance is simple at characteristics, are mainly used in the heating and the insulation of all kinds of gases of explosion-proof occasion and liquid.
The renewable core formula anti-explosion electric heater of the foregoing description, rated power is 20KW, and rated voltage is the alternating voltage of 380V, and heat medium is the medium that flows (as water, crude oil, chemical material and gas etc., operating pressure position 1.0MPa, working temperature is 80 ℃); Carry out according to GB3836.1-2000, GB3836.2-2000 standard, the explosion-proof ExdIIBT4 that is masked as, explosive-proof grade is IP56.
In sum, the renewable core formula anti-explosion electric heater of each embodiment of the utility model, owing to comprise container, inside at container is axially arranged with pyrotoxin, cooperate at first port of container to be provided with anti-explosion terminal box, anti-dry temperature probe and suction flange, cooperate at second port of container to be provided with explosion-proof temperature probe of outlet and outlet(discharge) flange; Pyrotoxin is replaceable, and heating evenly; Thereby can overcome that heating efficiency is low in the prior art, maintenance workload is big, cost is high and short defective in useful life, with realize the heating efficiency height, maintenance workload is little, cost is low and the advantage of long service life.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
