Abstract
The invention discloses a heat storage steam pipeline. The steam pipeline is characterized in that a groove-shaped cover plate of which both ends are in slope shapes is arranged in a steam pipe section; circular arcs which are tangential to a pipe cavity are arranged at both ends of the groove-shaped cover plate, the groove-shaped cover plate is arranged at the lower part of the pipe cavity, the circular arcs at both ends are tangential to the inner wall of the steam pipe section to be welded into a water collecting tank of which both sides are provided with gaps. Compared with the prior art, the steam pipeline disclosed by the invention has the advantages that the heat energy with condensate water is fully utilized, the heat waste of a pipe network is little, the structure is simple, the manufacture and the mounting are convenient, the investment is low, the recovery rate of the heat energy is high, the operating cost of the heat pipe network is effectively reduced, and the economic benefits of enterprises are improved. Besides, the steam pipeline is an energy saving and emission reducing measure with promotion and application values.
Description
Technical field
The present invention relates to heat distribution pipe network technical field, especially a kind of accumulation of heat steam line.
Background technique
The central heating network of delivery industry steam, the steam flow flowed in pipeline constantly changes, most of user's steam consumption on daytime is large, night, steam consumption was few, and a part of user's vapour on daytime, night, this rule made be superheat state the steam daytime in heat supply network pipe, and night becomes saturated vapour without vapour.After steam enters saturation state, produce condensed water because heat dissipation of pipeline causes in pipe, the condensed water in pipe does not accept for user, and condensed water also constitutes a threat to the safe operation of pipe network, and traditional way allows Guan Zhongning water be discharged to outside pipe by drain valve.For 1.0MPa(absolute pressure) water vapor, saturated vapour enthalpy equals 2777.12kj/kg, and the enthalpy of saturation water equals 762.68 kj/kg, and the water enthalpy of 20 DEG C is 84.51 kj/kg(natures).In heat supply network, water vapor is generated by the cool water heating of occurring in nature, and the condensed water enthalpy of discharging in pipe network about exceeds 680 kj/kg than natural water enthalpy.Heat supply network hydrophobic process makes 1/4th of production steam energy used in company with lost, and high-temperature-hot-water is discharged to outside pipe, to environment structure thermo-pollution, and initial ring guaranteed cost, and also natural water is processed into boiler feed water and also needs considerable cost.
The heat distribution pipe network of prior art, condensed water elimination causes heat-energy losses, not only reduces the thermal efficiency of heat supply network, also causes thermo-pollution to environment.
Summary of the invention
The object of the invention is a kind of accumulation of heat steam line designed for the deficiencies in the prior art, adopt pipe inner bottom part that the accumulation of heat structure of collecting annulus is set, steam gets up at the condensed water savings that the flow less period produces by collecting annulus, when in pipe, steam flow and temperature rise, high-temperature steam is by heat vaporized for the condensed water collected, the steam of vaporization and initial steam mixed flow are to user, thus avoid the discharge of condensed water, the heat loss of heat distribution pipe network is greatly reduced, the heat energy of condensed water is utilized effectively, not only avoid environmental thermal pollution, also improve the thermal efficiency of pipe network.
The object of the present invention is achieved like this: a kind of accumulation of heat steam line, is characterized in being provided with the flute profile cover plate that two ends are slope shape in steam pipeline section; Described flute profile cover plate two ends are provided with the circular arc tangent with tube chamber, and flute profile cover plate is arranged on tube chamber bottom, its two ends circular arc and steam pipeline section inwall tangent, be welded into the collecting annulus that both sides are provided with clearance gap.
Described collecting annulus and steam pipeline section are that parallel to an axis is arranged.
The heat energy that the present invention compared with prior art has condensed water is fully utilized, the heat waste of effective minimizing pipe network, structure is simple, make and easy for installation, and little investment, heat energy recycle rate is high, is a kind of energy-saving and emission-reduction measure having very much promotion and application to be worth, greatly reduce the operating cost of heat distribution pipe network, improve the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A schematic cross-section of Fig. 1;
Fig. 3 is the plan view of Fig. 1;
Fig. 4 ~ Fig. 5 is using state schematic diagram of the present invention.
Embodiment
Accompanying drawings 1, the present invention is made up of steam pipeline section 1 and collecting annulus 4, is provided with the flute profile cover plate 2 that two ends are slope shape in described steam pipeline section 1.
Accompanying drawings 2 ~ accompanying drawing 3, described flute profile cover plate 2 two ends are provided with the circular arc 5 tangent with tube chamber, and flute profile cover plate 2 is arranged on tube chamber bottom, and its two ends circular arc 5 is tangent and be welded into the collecting annulus 4 that both sides are provided with clearance gap 6 with steam pipeline section 1 inwall.Described collecting annulus 4 with steam pipeline section 1 for parallel to an axis is arranged.
Accompanying drawings 4 ~ accompanying drawing 5, the present invention is used on heat distribution pipe network, ducted steam flow changes with Day-night shift generating period, when steam flow reduces, in pipe network, original steam is that the steam pipeline section 1 of superheat state is little by little transformed into saturation state, along with steam flow continues to reduce, steam condition separation is constantly passed to vapour source point, and the condensed water 3 that saturated steam pipeline section 1 constantly generates flows into collecting annulus 4.When the steam flow through in steam pipeline section 1 becomes the superheated vapor of higher temperature again, the condensed water 3 be accumulated in collecting annulus 4 is vaporized, and the steam of vaporization and initial steam mixed flow are to user.Flute profile cover plate 2 two ends are slope shape, can prevent swiftly flowing steam from directly impacting condensed water 3 bottom steam pipeline section 1, both reduce vapor flow resistance, and steam can have been avoided again to be promoted by ponding, in pipe, form water column, cause steam and water bursting.
More than just the present invention is further illustrated, and be not used to limit this patent, allly implements for the present invention's equivalence, within the right that all should be contained in this patent.
Claims (2)
1. an accumulation of heat steam line, is characterized in that being provided with the flute profile cover plate that two ends are slope shape in steam pipeline section; Described flute profile cover plate two ends are provided with the circular arc tangent with tube chamber, and flute profile cover plate is arranged on tube chamber bottom, its two ends circular arc and steam pipeline section inwall tangent, be welded into the collecting annulus that both sides are provided with clearance gap.
