Abstract
The utility model discloses an oleum conveying pipeline. The oleum conveying pipeline is characterized by comprising an inner pipe, an outer pipe, a spiral heat-radiation piece, a steam source and a water drainage valve, wherein the inner pipe is sleeved with the outer pipe, the spiral heat-radiation piece is arranged between the outer pipe and the inner pipe, the outer side of the spiral heat-radiation piece is fixed to the outer pipe, the inner side of the spiral heat-radiation piece is fixed to the inner pipe, a spiral cavity is arranged between the spiral heat-radiation piece, the upper end of the spiral cavity is connected with the steam source, and the lower end of the spiral cavity is connected with the water drainage valve. By means of the technical scheme, the spiral heat-radiation piece and the outer pipe are arranged at the outer side of the conveying pipeline, and the spiral cavity is formed, steam is introduced into the spiral cavity to heat the inner pipe, so that the temperature of the inner pipe is kept, and the phenomenon of blockage of the pipeline caused by condensation of the oleum is prevented. Asbestos wraps the outer pipe to prevent heat loss, and the oleum conveying pipeline saves energy and protects the environment.
Description
Technical field
The utility model is specifically related to a kind of oleum conveyance conduit.
Background technique
In chemical industry, oleum is as a kind of industrial chemicals, especially 65% oleum is generally just condensed into solid in the time of 20 ℃, in the time of winter, need storage tank with pump, 65% oleum to be attained to a high place in groove, but its pipeline often stops up because 65% oleum is condensed into solid, need in tube wall outside, heat and could recover with hot water.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind ofly can remain pipe temperature, and making 65% oleum noncondensing is the oleum conveyance conduit of solid.
For achieving the above object, the technical solution of the utility model is as follows:
An oleum conveyance conduit, comprises inner tube, outer tube, spiral heat dissipation sheet, steam source and drain valve; Described outer tube sleeve is located at described inner tube outside, between described outer tube and inner tube, be provided with described spiral heat dissipation sheet, described spiral heat dissipation sheet outside is fixed on described outer tube, and described spiral heat dissipation sheet inner side is fixed in described inner tube, between described spiral heat dissipation sheet, is provided with spiraled cavity; Described spiraled cavity upper end connects described steam source, and its lower end connects described drain valve.
Preferably, described outer tube outside is coated with asbestos.
Pass through technique scheme, the utility model by spiral heat dissipation sheet and outward appearance described in conveyance conduit arranged outside, forms a spiraled cavity, and passes into therein steam and heat inner tube, thereby kept the temperature of inner tube, prevent because oleum condenses and cause the phenomenon of line clogging; In outer tube outside, be coated with asbestos, prevent heat loss, energy-conserving and environment-protective.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the disclosed a kind of oleum conveyance conduit of the utility model embodiment.
Numeral and the represented corresponding part title of letter in figure:
1. high position tank 2. inner tube 3. outer tube 4. spiral heat dissipation sheet 5. steam source 6. drain valve 7. drain valve 8. asbestos
Embodiment
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
The utility model provides a kind of oleum conveyance conduit, its working principle is: in spiral heat dissipation sheet and outward appearance described in conveyance conduit arranged outside, form a spiraled cavity, and pass into therein steam and heat inner tube, thereby kept the temperature of inner tube, prevent because oleum condenses and cause the phenomenon of line clogging.
Embodiment
As shown in Figure 1, high position tank 1 lower end is provided with described oleum conveyance conduit, comprises inner tube 2, outer tube 3, spiral heat dissipation sheet 4, steam source 5 and drain valve 6; Described outer tube 3 is sheathed on described inner tube 2 outsides, between described outer tube 3 and inner tube 2, be provided with described spiral heat dissipation sheet 4, described spiral heat dissipation sheet 4 outsides are fixed on described outer tube 5, and described spiral heat dissipation sheet 4 inner sides are fixed in described inner tube 2, between described spiral heat dissipation sheet 4, are provided with spiraled cavity 7; Described spiraled cavity 7 upper ends connect described steam source 5, and its lower end connects described drain valve 6; Described outer tube outside is coated with asbestos 8.
Pass through technique scheme, the utility model passes through in spiral heat dissipation sheet and outward appearance described in conveyance conduit arranged outside, form a spiraled cavity, and pass into therein steam and heat inner tube, thereby kept the temperature of inner tube, prevent because oleum condenses and cause the phenomenon of line clogging, the condensed water after steam-condensation is discharged by drain valve; In outer tube outside, be coated with asbestos, prevent heat loss, energy-conserving and environment-protective.
Above-described is only a kind of oleum conveyance conduit preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
