Abstract
The utility model relates to a coal economizer with a helical ribbed tube. One end of a snake-shaped tube panel (3) is connected with a collecting box (2) of a water outlet, the other end of the snake-shaped tube panel is connected with a collecting box (5) of a water inlet, a clamping plate (4) is arranged on the snake-shaped tube panel (3), and a steel tube of the snake-shaped tube panel is welded with a helical ribbed piece (1).
Description
The utility model is relevant with economizer.Especially relevant with boiler economizer.
Boiler economizer belongs to gas---the liquid heat exchanger, be usually placed in the convection pass, and generally pipe is placed to level and always keeps water to flow from bottom to top, flue gas flows from the top down, the feedwater of flue gas heat in steel pipe constantly passes to pipe like this.
The tube panel of existing boiler economizer is made up of light pipe or extended surface tube, and the complex heat transfer amount of parent tube unit length is few, the consume steel pipe, elbow is many, the weld bond number is also many, the probability of the quick-fried leakage of wearing and tearing is higher.
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, and the heat transfer efficiency height is saved raw material, the economizer of high life.
The utility model is achieved in that
The utility model spiral-finned tube economizer.An end that is S-shaped tube panel 3 is connected with delivery port header 2, and the other end is connected with water inlet header 5.Clamping plate 4 are arranged on the tube panel 3, and boxing has spiral fin 1 on the steel pipe of tube panel.
There is elbow the one or both ends of the utility model steel pipe, and the steel pipe of many band elbows is fixed into S-shaped tube panel 3 to being connected into snake-like tube row by clamping plate 4.
The utility model adopts spiral fin steel pipe extended surface, has reduced the outer heat transfer resistance of pipe, and light pipe can increase the complex heat transfer amount of parent tube per unit length relatively, thereby improves heat-transfer effect.
The utility model design feature mainly is to adopt the spiral-finned tube of alternating-current resistance soldering method boxing to form economizer, can expand more heat transfer area, therefore can save the more high quality seamless steel pipe than light pipe, extended surface tube etc.The used steel pipe of gilled tube economizer is few, and elbow number and weld bond number are also few, and the probability of the quick-fried leakage of wearing and tearing greatly reduces; It is possible that the row's of pipe number minimizing simultaneously makes suitable reduction cigarette rapid-result, and spiral fin has water conservancy diversion and the oblique action usefulness of scratching to flue gas in addition, thereby can weaken the wearing and tearing of flue gas to pipe greatly.
The utility model more and more obtains wide popularization and application as the technical measures of boiler anti-" the quick-fried leakage of four pipes " on station boiler.
Fig. 1 is steel-tube construction figure of the present utility model.
Fig. 2 is overall structure figure of the present utility model.
Following is embodiment of the present utility model:
The utility model is made elbow with spiral-finned tube 1 both ends or one end, then the spiral-finned tube butt joint of many band elbows is welded to connect and makes snake-like tube row, with clamping plate 4 snake-like tube row is fixedly made the spiral-finned tube S-shaped tube panel again, many group spiral-finned tube S-shaped tube panel one ends and water inlet header 5 are welded to connect, and the other end and delivery port header are welded to connect makes the spiral-finned tube economizer.
Claims (2)
1, a kind of spiral-finned tube economizer is characterized in that an end of S-shaped tube panel (3) is connected with delivery port header (2), and the other end is connected with water inlet header (5), and clamping plate (4) are arranged on the tube panel (3), and boxing has spiral fin (1) on the steel pipe of tube panel.
2, economizer according to claim 1 is characterized in that there is elbow the one or both ends of steel pipe, and the steel pipe of many band elbows is fixed into S-shaped tube panel (3) to being connected into snake-like tube row by clamping plate (4).
