Abstract
The utility model relates to a self cleaning and high performance heating pipe, which is mainly used for a hot water boiler heat transfer system. The utility model relates to a heating pipe with a concave-convex structure. The utility model is characterized in that the outer surface of a pipe body is evenly provided with circular or elliptical projections. After flue gas enters a pipeline, vortex flow turbulence can be formed to prolong flame detention time in the pipeline, enhance heat transfer efficiency, and effectively remove collecting scale gathering on the inner wall of the pipe body. The work efficiency can be improved owing to the increased contact area between flue gas and the wall of a pipe.
Description
The utility model relates to a kind of efficient heat transfer fire tube with self-cleaning function, is mainly used in the hot-water boiler heat transfer system.
Fire tube in the prior art in the boiler quirk mostly is the polishing surface, be that inwall, outer wall all are smooth surfaces, during the flame flow piping and the tube wall contact area is little, the thermal efficiency is low, and very tranquilly when flue gas flows can not produce the eddy current turbulence in fire tube, therefore can not remove the poly-dirt that accumulates on the fire tube inwall effectively, after long-term the use, along with thickening of poly-dirt, it is littler that the fire tube inner chamber becomes gradually, and contact area also reduces gradually, and the thermal efficiency also can be more and more lower.
The purpose of this utility model is to develop a kind of efficient heat transfer fire tube with self-cleaning function, and this fire tube has bigger contact surface, and can make flue gas form the eddy current turbulence in pipe, prolongs the holdup time of flame in fire tube, improves heat transfer efficiency.Simultaneously, the radial impact power that eddy current and turbulence produce is got off the poly-dirty loose or dislocation that is deposited on the tube wall, thereby guarantees the cleaning of inner-walls of duct, and improves heat conduction efficiency.
The purpose of this utility model is achieved in that it is a kind of fire tube that has concaveconvex structure, it is characterized in that the outer surface of fire tube body evenly is provided with circular or oval-shaped pit, and the wall surface relevant position is provided with circle or elliptical shaped lobes within it.
The utlity model has simple in structure, easy to make, economical and practical, efficient advantages of higher.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1: the utility model contour structures schematic diagram
Fig. 2: the utility model internal structure schematic diagram
Among the figure: 1---body, 2---pit, 3---inwall,
4---projection.
Referring to Fig. 1, Fig. 2, the utility model is a kind of fire tube that has concaveconvex structure, it is characterized in that evenly being provided with circle or oblong pits 2 at the outer surface of fire tube body 1, and wall 3 surperficial relevant positions are provided with circle or elliptical shaped lobes 4 within it.When flue gas enters body 1, because inwall 3 surfaces are provided with many protruding 4, make and form eddy current and turbulence in the flow of flue gas, prolong flame holdup time in fire tube, improve heat transfer efficiency, produced simultaneously radial impact power has prevented that sedimental gathering is also disposed the poly-dirt that in the past was deposited on tube wall effectively in the flue gas, simultaneously, because rough inner surface increases the contact area of flue gas and tube wall, thereby has improved heat exchange efficiency.Especially Qing Jie inner-walls of duct has prevented unnecessary heat loss.
