Abstract
The utility model provides a bushing type heating tube structure, wherein a heating tube bushing is welded on a tube plate; the upper edge of the heating tube bushing is higher than the upper plane of the tube plate; the bottom of the heating tube bushing is enclosed, and a semi-tight cylinder body with an opening at the upper end is formed; a straight cylinder type heating tube is inserted into the heating tube bushing; and the upper part of the straight cylinder type heating tube is exposed. When in use, if the heating tube is burnt out, only the damaged straight cylinder type heating tube needs to be changed and decompression and gas replacement are not needed to be carried out; therefore, the replacement is very convenient and the time is saved.
Description
Technical field
The utility model relates to heating tube, relates in particular to a kind of bushing type heating-pipe structure that is applicable to the flammable explosive gas drying system.
Background technology
At present, in gas-drying system, U type heating tube is welded on the tube sheet, in running, the heating tube easy burn-out, because the operating pressure of system is 0.8～3.2Mpa, gas is inflammable and explosive gas, if heating tube burns out, must stop equipment, pressure release could be changed whole heating tube tube sheet flange after displacement is finished, and causes very big inconvenience to use.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of bushing type heating-pipe structure that is used for the flammable explosive gas drying system is provided.
The purpose of this utility model is achieved through the following technical solutions:
The bushing type heating-pipe structure, characteristics are: be welded with the heating tube sleeve pipe on tube sheet, the upper edge of described heating tube sleeve pipe is higher than the last plane of tube sheet, the bottom lock of heating tube sleeve pipe, the semitight cylindrical shell of formation upper end open; The straight barrel type heating tube inserts in the heating tube sleeve pipe, and expose on the top of straight barrel type heating tube.
Further, above-mentioned bushing type heating-pipe structure, wherein, the upper edge of described heating tube sleeve pipe is higher than plane 10～15mm on the tube sheet.
Further, above-mentioned bushing type heating-pipe structure, wherein, 15～20mm is exposed on the top of described straight barrel type heating tube.
Again further, above-mentioned bushing type heating-pipe structure, wherein, the external diameter of described straight barrel type heating tube is than the little 1～2mm of internal diameter of heating tube sleeve pipe.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
The heating tube Socket welding directly inserts the straight barrel type heating tube in the heating tube sleeve pipe on tube sheet, if burn out, needn't pressure release and substitution gas, and straight barrel type heating tube that need only worse damage gets final product, and has saved valuable time and operating cost.Its structure is very simple, and it is very convenient to change.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: the scheme of installation of the utility model heating tube.
The implication of each Reference numeral sees the following form among the figure:
The 1-tube sheet, 2-heating tube sleeve pipe, 3-straight barrel type heating tube.
Embodiment
As shown in Figure 1, the bushing type heating-pipe structure is welded with heating tube sleeve pipe 2 on tube sheet 1, the material of heating tube sleeve pipe 2 is a seamless stainless steel, the upper edge of heating tube sleeve pipe 2 is higher than the last plane 10～15mm of tube sheet, the bottom lock of heating tube sleeve pipe 2, the semitight cylindrical shell of formation upper end open; Straight barrel type heating tube 3 inserts in the heating tube sleeve pipe 2, and 15～20mm is exposed on the top of straight barrel type heating tube 3, and the external diameter of straight barrel type heating tube 3 is than the little 1～2mm of internal diameter of heating tube sleeve pipe 2.
Heating tube sleeve pipe 2 is welded on the tube sheet 1, directly straight barrel type heating tube 3 is inserted in the heating tube sleeve pipes 2 then, if burn out, needn't pressure release and substitution gas, the straight barrel type heating tube 3 that need only change damage gets final product, and has saved valuable time and operating cost.
As fully visible, the utility model modern design, simple for structure, in the flammable explosive gas drying system, will have U type heating tube now and change the bushing type heating tube into, very easy to use, low cost of manufacture.
What need understand is: the above only is a preferred implementation of the present utility model; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
