Abstract
The invention discloses an efficient heat exchange flue which mainly solves the technical problems that the flue gas quickly passes through the flue, the heat exchange efficiency is relatively low and the like in the heat exchange process of the existing common smoke tube. The technical scheme of the efficient heat exchange flue is characterized in that: a glue gas baffling piece is sleeved in the flue (1) and comprises a baffling piece body (2), through holes (3) and folding pieces (4), wherein two or more through holes (3) are cut on a straight-plate baffling piece body (2); and crossing folding pieces (4) with a stopping function are arranged on the upper part of each through hole (3) opposite to the two sides of the baffling piece body (2) respectively. After the efficient heat exchange flue disclosed by the invention is mounted in a smoke tube of the traditional vertical flame-tube fuel oil and fuel gas boilers, the smoke is forcibly pulled back to move upwards in the smoke tube, thus the moving time of the smoke in the smoke tube is prolonged, the heat exchange with the wall of smoke tube is enhanced, and the energy-saving effect is more obvious. The efficient heat exchange flue is mainly applied to the fuel oil and fuel gas flame-tube hot-water boilers and household small hot-water boilers.
Description
Technical field
The present invention relates to a kind of efficient heat exchange flue that is used for heat exchange.
Background technology
At present, common smoke pipe mainly is straight pipe in heat exchanging process, and fast by flue, the efficient of carrying out heat exchange is lower in flue for flue gas.
Summary of the invention
The purpose of this invention is to provide the efficient heat exchange flue that a kind of heat exchanger effectiveness significantly improves.
The technical solution adopted for the present invention to solve the technical problems is: suit flue gas baffling sheet in flue 1, flue gas baffling sheet comprises baffling lamellar body 2, through hole 3 and tabs 4, on straight tabular baffling lamellar body 2, be cut with the through hole 3 more than 2 or 2, the relative baffling lamellar body 2 both sides tabs 4 that barrier effect has been arranged arranged in a crossed manner respectively on the top of each through hole 3, the width of baffling lamellar body 2 is less than or equal to the internal diameter of flue 1.When cutting through hole 3 on baffling lamellar body 2, does not cut on through hole 3 tops, and the cutting of through hole 3 is partly stretched out respectively successively to the left and right, has formed the tabs 4 of barrier effect on through hole 3 tops.Described through hole 3 is a semicircle shape.Angle between tabs 4 and the baffling lamellar body 2 is equal to or less than 90 degree.
The invention has the beneficial effects as follows: in the smoke pipe that invention is installed in traditional vertical fire tube fuel oil, gas fired-boiler, making flue gas be forced to turn back in smoke pipe upwards moves, flue gas prolongs running time in smoke pipe, strengthen with the heat exchange of smoke pipe wall, thereby it is more remarkable to make it energy-saving effect.It mainly is to be applied on fuel oil, combustion gas fire tube hot-water boiler and the domestic small hot-water boiler.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further details.
Embodiment 1, the present invention constitutes by suit flue gas baffling sheet in flue 1, flue gas baffling sheet comprises baffling lamellar body 2, through hole 3 and tabs 4, on straight tabular baffling lamellar body 2, be cut with the through hole 3 more than 2 or 2, be theoretically, The more the better, the relative baffling lamellar body 2 both sides left and right sides tabs 4 that barrier effect has been arranged arranged in a crossed manner respectively on the top of each through hole 3, for easy to process and play barrier effect better, described tabs 4 preferably is made into semicircle shape, theoretically, it is best that the radius of tabs 4 equals 1/2nd of baffling lamellar body 2 width, thereby plays barrier effect better; But be easy to process, make the radius of tabs 4 be slightly less than 1/2nd of baffling lamellar body 2 width and get final product.Consult Fig. 1 to Fig. 3.
Described flue gas baffling sheet can adopt the sheet material of 0.5 millimeters thick, and material preferably adopts 1Cr18Ni9Ti, and it can bear 900 ℃ flue-gas temperature.For easy to process, the width of baffling lamellar body 2 is little 2 millimeters than the smoke pipe internal diameter, goes out a plurality of semicircle camber lines through punch press, and a first from left parts not outside knuckle on the right side and formed tabs 4 for 90 ° then.
The present invention is sleeved in the flue 1, and the width of baffling lamellar body 2 is slightly less than or equals the internal diameter of flue 1, makes to form between flue 1 inwall and the baffling lamellar body 2 to closely cooperate as far as possible, thereby makes it to install and use conveniently, can play the choked flow effect better again.Consult Fig. 4 to Fig. 5.
Place flue gas baffling sheet in the smoke pipe of traditional vertical fire tube fuel oil, gas fired-boiler, make flue gas be forced to turn back in smoke pipe and upwards move, flue gas prolongs running time in smoke pipe, with the heat exchange enhancing of smoke pipe wall.Through overtesting and calculating: the coefficient of heat transfer of flue gas and smoke pipe wall is up to 98Kcal/m
2℃, be the coefficient of heat transfer (19Kcal/m of light pipe
2℃) 5 times, be the coefficient of heat transfer (27Kcal/m of threaded flue
2℃) 3.5 times.Because the huge raising of the coefficient of heat transfer can reduce 70% with the stream heating surface area, makes this traditional type of furnace reduce 40% on volume and weight, cost significantly reduces.The raising of the coefficient of heat transfer makes exhaust gas temperature reduce to about 110 ℃, and boiler overall thermal efficient is up to more than 90%, and energy-saving effect is remarkable.
