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 the dismountable anti-explosion electric heater assembly of a kind of high pressure that heated air, liquid are used in the explosive substance occasion is arranged.
Background technology
In the explosive substance occasion is arranged, anti-explosion electric heater heated air commonly used, liquid, operation principle is: gas or liquid get in the pressure vessel of anti-explosion electric heater from inlet; Through the electric heating straight tube; Elevated temperature is gone out from outlet, and arrival needs the place of uniform temperature.The 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 to be 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 are shared.During the anti-explosion electric heater operate as normal, vessel internal pressure power is higher, reaches 15MPa.Be the sealing property that guarantees that anti-explosion electric heater is whole; Original technical scheme is: heat radiation sleeve pipe top is welded on the cylinder bottom plate; Electric heating straight tube and the upper end welding of heat radiation sleeve pipe; Heat radiation sleeve pipe lower end is welded on the tube sheet flange, forms some anti-explosion electric heater assemblies, it is connected with pressure vessel with the tube sheet flange gasket through the tube sheet flange.The electric heating straight tube is the rapid wear body; But can not damage simultaneously; After using certain hour, produce damages when needing replacing as certain electric heating straight tube, can not single nondestructive demounting, replacing; Must all electric heating straight tubes 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: a kind of anti-explosion electric heater assembly that abbreviates as is provided, and full name is the dismountable anti-explosion electric heater assembly of high pressure, and the electric heating straight tube is not and the upper end welding of heat radiation sleeve pipe; But weld with boss sleeve pipe upper end, the pit external thread sleeve is welded on the heat radiation sleeve pipe, is with sealing gasket on the electric heating straight tube; The electric heating straight tube puts in pit external thread sleeve and the heat radiation sleeve pipe, and nut packs into from electric heating straight tube top, when screwing nut; It is downward to drive the boss sleeve pipe; Compress sealing gasket, produce sealing function, make to keep high pressure in the pressure vessel.After certain electric heating straight tube damages; Unscrew nut; Nut is taken out from the electric heating straight tube; The electric heating straight tube just can be taken out from heat radiation sleeve pipe, pit external thread sleeve together with boss sleeve pipe, sealing gasket easily, carries out list harmless changeing, and keeps 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 of taking out, sealing gasket can be repeatedly used.
Adopt above technical scheme, its effect is conspicuous:
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 the pressure vessel in the anti-explosion electric heater.
2, cost saving.Some electric heating straight tubes in the 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 material and make the total expense and account for 4/5ths of the whole total value of anti-explosion electric heater; Adopt the dismountable anti-explosion electric heater assembly of this high pressure; Whenever change an electric heating straight tube, just can save the expense of the whole total value of 4/5ths anti-explosion electric heater.
3, change conveniently.

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.
Among the 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, and electric heating straight tube 6 is welded on the upper end of boss sleeve pipe 10; Pit external thread sleeve 12 is welded on the heat radiation sleeve pipe 4; Pit on boss on the boss sleeve pipe and the pit external screw thread on the line is complementary, and is with sealing gasket 11 on the electric heating straight tube 6, and the electric heating straight tube puts in pit external thread sleeve 12 and the 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, matches with pit external thread sleeve 12, and nut can be screwed on the pit external thread sleeve and unscrew easily.When screwing nut 8, it is downward to drive the boss sleeve pipe, compresses sealing gasket, produces sealing function, makes in the pressure vessel 7 to keep high pressure.When certain electric heating straight tube and after damaging through using after a while; When unscrewing nut; Nut is taken out from the electric heating straight tube; The electric heating straight tube just can be taken out together with boss sleeve pipe, sealing gasket, carries out list harmless changeing, and keeps 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.
