Description
Technical field
The present invention relates to heat distribution pipe network technical field, especially a kind of accumulation of heat jet chimney.
Background technology
The central heating network of delivery industry steam, in pipeline, the quantity of steam of flowing constantly changes, most of user's steam consumptions on daytime are big, 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, becomes saturated vapor night without vapour.When steam enters after saturation, owing to heat dissipation of pipeline causes generation condensed water in pipe, the condensed water in pipe is not for user's acceptance, and condensed water also safe operation to pipe network constitutes a threat to, and traditional way is to allow Guan Zhongning water be discharged to outside pipe by drain valve.By 1.0MPa(absolute pressure) as a example by water vapour, saturated vapor enthalpy is equal to 2777.12kj/kg, the enthalpy of saturation water is equal to 762.68 kj/kg, and the water enthalpy of 20 DEG C is 84.51 kj/kg(natures).In heat supply network, water vapour is to be generated by the cool water heating in nature, and the condensed water enthalpy discharged in pipe network about exceeds 680 kj/kg than natural water enthalpy.Heat supply network hydrophobic process makes 1/4th of energy used by production steam in company with lost, and high-temperature-hot-water is discharged to outside pipe, and to environment structure thermal pollution, initial ring guaranteed cost, and natural water is processed into boiler feedwater is also required to 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 environment is caused thermal pollution.
Summary of the invention
It is an object of the invention to a kind of accumulation of heat jet chimney designed for the deficiencies in the prior art, use pipe inner bottom part that the accumulation of heat structure of water leg is set, steam is got up by water leg at the condensed water savings that the flow less period produces, when in pipe, steam flow and temperature rise, the condensed water heating vaporization that high-temperature steam will be collected, the steam of vaporization mixes with initial steam and flows to user, thus avoid the discharge of condensed water, the thermal loss making heat distribution pipe network greatly reduces, 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 jet chimney, is provided with the flute profile cover plate that two ends are ramped shaped in being characterized 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, and its two ends circular arc is tangent with steam pipeline section inwall, are welded into both sides and are provided with the water leg of clearance gap.
Described water leg and steam pipeline section are for being arranged in an axially parallel mode.
The present invention compared with prior art has the heat energy of condensed water and is fully utilized, effectively reduce the heat waste of pipe network, simple in construction, make and easy for installation, and small 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, it is substantially reduced the operating cost of heat distribution pipe network, improves the economic benefit of enterprise.

Fig. 2 is the Section A-A schematic diagram of Fig. 1；
Fig. 3 is the top view of Fig. 1；
Fig. 4 ~ Fig. 5 is that the present invention uses view.
Detailed description of the invention
Refering to accompanying drawing 1, the present invention is made up of steam pipeline section 1 and water leg 4, is provided with the flute profile cover plate 2 that two ends are ramped shaped in described steam pipeline section 1.
Refering to accompanying drawing 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 with steam pipeline section 1 inwall and is welded into both sides and is provided with the water leg 4 of clearance gap 6.Described water leg 4 and steam pipeline section 1 are for being arranged in an axially parallel mode.
Refering to accompanying drawing 4 ~ accompanying drawing 5, the present invention is used on heat distribution pipe network, steam flow in pipeline 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 progressively transformed into saturation, along with steam flow continues to reduce, steam condition separation constantly elapses to vapour source point, and the condensed water 3 that saturated steam pipeline section 1 is continuously generated flows into water leg 4.When the steam flow through in steam pipeline section 1 becomes the superheated steam of higher temperature again, the condensed water 3 being accumulated in water leg 4 is vaporized, and the steam of vaporization mixes with initial steam and flows to user.Flute profile cover plate 2 two ends are ramped shaped, can prevent swiftly flowing steam from directly impacting the condensed water 3 bottom steam pipeline section 1, have both reduced steam flow resistance, and steam can be avoided again to be promoted by hydrops, form water column, cause steam and water bursting in pipe.
More than simply the present invention is further illustrated, and is not used to limit this patent, all implements for equivalence of the present invention, within being intended to be limited solely by the right of this patent.
