Abstract
The utility model relates to a kind of cracker of chemical industry resin, comprise the evaporimeter, cracking tube, the cooling collector that connect successively, cracking tube with directly being held by import, bending part and outlet directly hold the U-shaped structure formed, this device also comprises the vacuum generator being connected to cooling collector; In cracking tube, device has heating wire, and heating wire curl is through in cracking tube, and cracking tube is stretched out and and Electrode connection respectively in the two ends of heating wire.The utility model is directly heated in cracking tube by heating wire, substantially increases the efficiency of heating surface, the almost free of losses of its energy, and can not impact cracking tube, and 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; Adopt end vacuum suction apparatus, be beneficial to gasiform cracking stock by cracking tube, improve lysis efficiency.
Description
Technical field
The utility model relates to the processing technique field of chemical industry resin, particularly relates to the cracker for 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, provides a kind of cracker of chemical industry resin, 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 cracker for chemical industry resin, comprises the evaporimeter, cracking tube, the cooling collector that connect successively, cracking tube with directly being held by import, bending part and outlet directly hold the U-shaped structure formed, this device also comprises the vacuum generator being connected to cooling collector; In described cracking tube, device has heating wire, and heating wire curl is through in cracking tube, and cracking tube is stretched out and and Electrode connection respectively in the two ends of heating wire.
Further improvement as technique scheme:
Described heating wire comprises and is arranged in import and directly holds, export the part of rarefaction of straight end and be positioned at the compact part of 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; Adopt end vacuum suction apparatus, be beneficial to gasiform cracking stock by cracking tube, improve lysis efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, cracking tube; 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; 4, cooling collector; 5, vacuum generator; 6, evaporimeter.
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 cracker of the chemical industry resin of the present embodiment, comprise the evaporimeter 6, cracking tube 1, the cooling collector 4 that connect successively, cracking tube 1 with directly being held 11 by import, the U-shaped structures that form of bending part 13 and the straight end 12 of outlet, this device also comprises the vacuum generator 5 being connected to cooling collector 4; In cracking tube 1, device has heating wire 2, and heating wire 2 curl is through in cracking tube 1, and the two ends of heating wire 2 are stretched out cracking tube 1 respectively and are connected with electrode 3.
Heating wire 2 comprise be arranged in that import directly holds 11, the part of rarefaction 21 of the straight end 12 of outlet and be positioned at the compact part 22 of bending part 13, 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; Adopt end vacuum suction apparatus, be beneficial to gasiform cracking stock by cracking tube, improve lysis efficiency.
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.
