Abstract
The utility model relates to a kind of chemical industry resin cracking tube, and comprise the body of U-shaped structure, in described body, device has heating wire, heating wire curl through in body, the two ends of heating wire stretch out body respectively and and Electrode connection; Described heating wire comprises the import being arranged in body and directly holds and export the part of rarefaction of straight end and be positioned at the compact part of body bending part, and the screw pitch of the heating wire of compact part is less than the screw pitch of part of rarefaction.The utility model is directly heated in cracking tube by heating wire, compare the mode of heating of cracking tube external heat, heat transfer and cracking tube heating itself, substantially increase the efficiency of heating surface, the almost free of losses of its energy, and can not impact cracking tube, its long service life, cost are low; Heating wire adopts pitch variation structure, prevents that the gas raw material of the bending part of U-shaped cracking tube is intensive and cracking is insufficient, improves lysis efficiency, reduce energy consumption.
Description
Technical field
The utility model relates to the processing technique field of chemical industry resin, particularly relates to the cracking tube for the cracking of chemical industry resin.
Background technology
In chemical industry production of resins, usually need raw material to carry out cracking, cracking process carries out in cracking tube.Need liquid charging stock to be heated into gas during cracking, gas passes in cracking tube and carries out Pintsch process.The mode of heating of existing cracking tube is produced heat by the heater strip energising of its outer surface and is passed in cracking tube by heat.The heat transfer efficiency of this mode of heating is lower, and heat-energy losses is very large, causes that whole firing equipment energy consumption is high, cost is high.
Existing mode of cracking tube direct-electrifying being carried out heating pyrolyze, which raises the utilization rate of heat energy, reduces equipment energy consumption at present, but due to cracking tube energising self-heating, the life-span of cracking tube shortens greatly, needs often to change, and its cracking cost is still higher.
Utility model content
The above-mentioned shortcoming that the applicant exists for prior art, carries out studying and designing, and provides a kind of chemical industry resin cracking tube, heat transfer efficiency is high, energy consumption is low, cost is low feature that it has.
The technical scheme that the utility model adopts is as follows:
A kind of chemical industry resin cracking tube, comprise the body of U-shaped structure, in described body, device has heating wire, and heating wire curl is through in body, and body is stretched out and and Electrode connection respectively in the two ends of heating wire.
Further improvement as technique scheme:
Described heating wire comprises the import being arranged in body and directly holds and export the part of rarefaction of straight end and be positioned at the compact part of body bending part, and the screw pitch of the heating wire of compact part is less than the screw pitch of part of rarefaction.
The beneficial effects of the utility model are as follows:
The utility model is directly heated in cracking tube by heating wire, compare the mode of heating of cracking tube external heat, heat transfer and cracking tube heating itself, substantially increase the efficiency of heating surface, the almost free of losses of its energy, and can not impact cracking tube, its long service life, cost are low; Heating wire adopts pitch variation structure, prevents that the gas raw material of the bending part of U-shaped cracking tube is intensive and cracking is insufficient, improves lysis efficiency, reduce energy consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, body; 11, import is directly held; 12, outlet is directly held; 13, bending part; 2, heating wire; 21, part of rarefaction; 22, compact part; 3, electrode.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the chemical industry resin cracking tube of the present embodiment, comprise the body 1 of U-shaped structure, in body 1, device has heating wire 2, and heating wire 2 curl is through in body 1, and the two ends of heating wire 2 are stretched out body 1 respectively and are connected with electrode 3.
Heating wire 2 comprises the import being arranged in body 1 and directly holds the part of rarefaction 21 of 11 and the straight end 12 of outlet and be positioned at the compact part 22 of body 1 bending part 13, and the screw pitch of the heating wire 2 of compact part 22 is less than the screw pitch of part of rarefaction 21.
The utility model is directly heated in cracking tube by heating wire, compare the mode of heating of cracking tube external heat, heat transfer and cracking tube heating itself, substantially increase the efficiency of heating surface, the almost free of losses of its energy, and can not impact cracking tube, its long service life, cost are low; Heating wire adopts pitch variation structure, prevents that the gas raw material of the bending part of U-shaped cracking tube is intensive and cracking is insufficient, improves lysis efficiency, reduce energy consumption.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
