Abstract
The invention discloses a high-pressure detachable/replaceable anti-explosion electric heater assembly which is arranged on an anti-explosion electric heater and used for heating gas and liquid in occasions with the presence of explosive substances. The anti-explosion electric heater assembly comprises heat-radiating casing pipes, electric-heating straight pipes, nuts, boss casing pipes, sealing gaskets and pit outer thread bushings. The anti-explosion electric heater assembly is characterized in that the electric-heating straight pipes are welded on the upper ends of the boss casing pipes, the pit outer thread bushings are welded on the heat-radiating casing pipes, the electric-heating straight pipes are sleeved with the sealing gaskets and extend into the pit outer thread bushings and the heat-radiating casing pipes, and the nuts are sleeved from the upper parts of the electric-heating straight pipes. When the nuts are screwed down, the boss casing pipes are driven to move downwards to tightly press the sealing gaskets so as to produce a sealing effect, and thus, high pressure is kept in a pressure container. When a certain electric-heating straight pipe is damaged after being used for a certain period of time, the electric-heating straight pipe can be taken out together with the boss casing pipe and the sealing gasket by loosening the nut, and thus, the nondestructive detachment and replacement of a single electric-heating straight pipe can be performed conveniently. The anti-explosion electric heater assembly is good in sealing performance, is convenient to detach and replace, and saves the cost; and each detachment and replacement of the electric-heating straight pipe can save four fifths of the cost for the total value of the entire anti-explosion electric heater.
Description
Technical field
The present invention is a kind ofly having the dismountable anti-explosion electric heater assembly of the high pressure of heated air, liquid in explosive substance occasion.
Background technology
Having in explosive substance occasion, conventional anti-explosion electric heater heated air, liquid, operation principle is: gas or liquid enter in the pressure vessel of anti-explosion electric heater from entrance, through electric heating straight tube, elevated temperature, goes out from outlet, arrives the place needing uniform temperature.Anti-explosion electric heater critical piece is some anti-explosion electric heater assemblies, is made up of explosion-proof wiring cylindrical shell, cylinder bottom plate, heat radiation sleeve pipe, heating panel, tube sheet flange and some electric heating straight tubes.Wherein cylinder bottom plate is welded on explosion-proof wiring cylindrical shell lower end, and explosion-proof wiring cylindrical shell, cylinder bottom plate, heating panel, tube sheet flange are that all anti-explosion electric heater assemblies share.When anti-explosion electric heater normally works, reservoir pressure is higher, reaches 15MPa.For ensureing the sealing property of anti-explosion electric heater entirety, original technical scheme is: heat radiation sleeve pipe upper weld is on cylinder bottom plate, electric heating straight tube welds with heat radiation sleeve upper end, heat radiation its lower end is welded on tube sheet flange, form some anti-explosion electric heater assemblies, with tube sheet flange gasket, it is connected with pressure vessel by tube sheet flange.Electric heating straight tube is rapid wear body, but can not damage simultaneously, after using certain hour, when there being certain electric heating straight tube generation damage to need to change, can not single nondestructive demounting, replacing, all electric heating straight tubes must be changed together with explosion-proof wiring cylindrical shell, cylinder bottom plate, heat radiation sleeve pipe, heating panel, tube sheet flange, cause the waste of material and manufacturing cost.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of referred to as anti-explosion electric heater assembly, full name is the dismountable anti-explosion electric heater assembly of high pressure, electric heating straight tube is not weld with heat radiation sleeve upper end, but weld with boss sleeve upper end, pit external thread sleeve is welded on heat radiation sleeve pipe, on electric heating straight tube, cover has sealing gasket, electric heating straight tube puts in pit external thread sleeve and heat radiation sleeve pipe, nut packs into from electric heating straight tube top, when tightening nut, drive boss sleeve pipe downward, press seal pad, produce sealing function, make in pressure vessel, to keep 15Mpa high pressure.After certain electric heating straight tube damages, loosening nut, nut is taken out from electric heating straight tube, electric heating straight tube just can be taken out together with boss sleeve pipe, sealing gasket easily from heat radiation sleeve pipe, pit external thread sleeve, carry out that list is only harmless to be changed, retain explosion-proof wiring cylindrical shell, cylinder bottom plate, pit external thread sleeve, heat radiation sleeve pipe, heating panel, tube sheet flange and other unspoiled electric heating straight tubes.The nut taken out, sealing gasket can repeatedly use.
Adopt above technical scheme, its effect is apparent:
1, good seal.The sealing effectiveness of the dismountable anti-explosion electric heater assembly of high pressure, is equal to the sealing effectiveness of former technical scheme anti-explosion electric heater assembly, keeps the high pressure in pressure vessel in anti-explosion electric heater.
2, cost saving.The material of some electric heating straight tubes in anti-explosion electric heater and explosion-proof wiring cylindrical shell, cylinder bottom plate, pit external thread sleeve, heat radiation sleeve pipe, heating panel, tube sheet flange and make that total expense accounts for the overall total value of anti-explosion electric heater 4/5ths, adopt the dismountable anti-explosion electric heater assembly of this high pressure, often change an electric heating straight tube, just can save the expense of the overall total value of anti-explosion electric heater of 4/5ths.
3, change conveniently.
Accompanying drawing explanation
Fig. 1 is the anti-explosion electric heater structure diagram of original technical scheme.
Fig. 2 is the anti-explosion electric heater structure diagram in the dismountable anti-explosion electric heater assembly of high pressure.
In figure: 1, explosion-proof wiring cylindrical shell 2, cylinder bottom plate 3, heating panel 4, heat radiation sleeve pipe 5, tube sheet flange 6, electric heating straight tube 7, pressure vessel 8, nut 9, tube sheet flange gasket 10, boss pipe box 11, sealing gasket 12, pit external thread sleeve
Concrete practice mode
With reference to Fig. 1, Fig. 2, the present invention is the dismountable anti-explosion electric heater assembly of a kind of high pressure, electric heating straight tube 6 is welded on the upper end of boss sleeve pipe 10, pit external thread sleeve 12 is welded on heat radiation sleeve pipe 4, pit on boss on boss sleeve pipe 10 and pit external thread sleeve 12 matches, on electric heating straight tube 6, cover has sealing gasket 11, electric heating straight tube puts in pit external thread sleeve 12 and heat radiation sleeve pipe 4, sealing gasket 11 is positioned at the cooperation place of boss and pit, nut 8 packs into from electric heating straight tube top, match with pit external thread sleeve 12, nut can carry out easily screwing and unscrewing on pit external thread sleeve.When tightening nut 8, drive boss sleeve pipe downward, press seal pad, produce sealing function, make to keep 15Mpa high pressure in pressure vessel 7.After certain electric heating straight tube damages through using after a while, during loosening nut, nut is taken out from electric heating straight tube, electric heating straight tube just can be taken out together with boss sleeve pipe, sealing gasket, carry out that list is only harmless to be changed, retain explosion-proof wiring cylindrical shell 1, cylinder bottom plate 2, pit external thread sleeve 12, heat radiation sleeve pipe 4, heating panel 3, tube sheet flange 5 and other unspoiled electric heating straight tubes.
