Abstract
An inserting twist-belt type turbolator for forced heat transfer in pipe equipped in the fire tube of the boiler or the heat exchanger tube, is characterized in that the cross-section vertical to the axis is in a rectangular shape or approximate to a rectangular shape, the long side of the rectangle is equal to or slightly smaller than the inner diameter of the fire tube or the heat exchanger tube, the both ends of the consecutive cross-sections are arranged at two radically symmetrical sides of the axial line according to the equidistance spiral line. The degree of distortion of the inserting twist-belt type turbolator made of the thin metal belt is 4-10. The utility model has easy producing, convenient assembly, little investment and great profit, can improve the heat efficiency of the boiler or the heat exchanger by 1-5%, can extend the ash removal time, and is convenient for ash discharging.
Description
The utility model is the parts about chamber structure, especially about being used for the heat transfer part in smoke pipe or the heat exchanger tube.
The smoke pipe of small-sized fire tube boiler is made up of the seamless steel pipe of a branch of hollow, when in smoke pipe, flowing as the high-temperature flue gas of heat release medium since no any stopping in the pipe be parallel to the steady stream of managing axial line so its motion state is.Under the operating mode of this steady stream, the heat release medium contacts what carry out heat exchange with tube wall only be that part of near tube wall, and fail to be used well near the contained heat energy of that part of heat release medium of die, causes the raising that influences boiler thermal output.In the above-mentioned Boiler smoke tube, the heat release medium heat exchanges existing this defective, equally also is present in the general heat exchanger that the heat release medium is flowed in pipe.
The purpose of this utility model is to provide a kind of heat release medium that changes in Boiler smoke tube or the Tube Sheet of Heat Exchanger to move to around the part of managing the turbulent flow that axial line advances twist along being parallel to the steady stream of manage axial line.
The purpose of this utility model is achieved in that a kind of insertion twisted strip formula turbolator that is arranged on the smoke pipe or the reinforcement intraductal heat transfer in the Tube Sheet of Heat Exchanger of boiler, it is characterized in that perpendicular to the cross section of axial line rectangular or approximate rectangular, the long limit of cross section is equal to or slightly less than the internal diameter of smoke pipe/Tube Sheet of Heat Exchanger, and the two ends of continuous cross section split the both sides of penetrating symmetry in the axle center wire spoke by equidistant helix mutually.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is structural representation of the present utility model.
The insertion twisted strip formula turbolator 2 that is positioned at smoke pipe or Tube Sheet of Heat Exchanger 1 is to be the distortion shoestring at center with its axial line I-I.It is rectangular or approximate rectangular perpendicular to the cross section of axial line I-I to insert twisted strip formula turbolator 2, and the long limit of rectangle is equal to or slightly less than the internal diameter r of smoke pipe or Tube Sheet of Heat Exchanger 1.For this reason, inserting twisted strip formula turbolator 2 can insert in smoke pipe or the Tube Sheet of Heat Exchanger 1 easily.The two ends of inserting the mutual continuous cross section of twisted strip formula turbolator 2 split the both sides of penetrating symmetry at the axial line I-I width of cloth by equidistant helical, and the ratio of the internal diameter r of the pitch t of equidistant helix and pipe is 4～10.This ratio is the torsion resistance R that inserts twisted strip formula turbolator 2, that is:
R＝ (t)/(r) ＝4～10
Like this, insert twisted strip formula turbolator 2 smoke pipe or Tube Sheet of Heat Exchanger 1 inside are divided into two passages that twine mutually symmetrically.
In the time of in heat release media such as high-temperature flue gas enter smoke pipe or Tube Sheet of Heat Exchanger 1, be subjected to inserting the guiding of twisted strip formula turbolator 2, be divided into symmetrical two strands, the turbulent operating mode that in smoke pipe or Tube Sheet of Heat Exchanger 1, is the screw of fierceness around axial line I-I, heat energy near die heat release medium is partly fully partly spread to tube wall, and increased the contact length of heat release medium and tube wall, the carrying out that helps heat exchange, thereby improved the thermal efficiency of boiler or heat exchanger, generally can improve the thermal efficiency 1～5%.Torsion resistance R is too small, and the resistance of ducting is excessive, and excessive then heat transfer efficiency is poor.When torsion resistance R=2.9, the resistance of ducting is less, and heat transfer efficiency is higher.Inserting the distortion of twisted strip formula turbolator 2 usefulness metal strips makes.
The utlity model has and make simply, easy for installation, the thermal efficiency of raising boiler or heat exchanger, small investment, the advantage that income is high. Especially can reduce dust stratification to Boiler smoke tube, prolong cleaning cycle; During deashing, only need insertion twisted strip formula turbolator is extracted and ash can be cleared out in managing, simplified purge mode and labour intensity. In addition, it can make boiler volume reduce, or increases boiler output and accelerate the rate of rise.
Claims (3)
1, a kind of insertion twisted strip formula turbolator that is arranged on the smoke pipe or the reinforcement intraductal heat transfer in the Tube Sheet of Heat Exchanger of boiler, it is characterized in that perpendicular to the cross section of axial line rectangular or approximate rectangular, the long limit of described rectangle is equal to or slightly less than the internal diameter of smoke pipe or Tube Sheet of Heat Exchanger, and the two ends in continuous cross section split the both sides of penetrating symmetry in the axle center wire spoke by equidistant helix mutually.
2, insertion twisted strip formula turbolator according to claim 1 is characterized in that torsion resistance R value is 4～10.
