Abstract
The utility model discloses a heat transfer fire tube which is characterized in that the inner wall surface of the heat transfer fire tube is provided with a plurality of humps. After entering the tube, fume forms turbulent flow and can extend the time of heat exchange; meanwhile, the humps also increase the area of heat exchange; thereby, the heat transfer efficiency can be improved, and the fouling in tube can be effectively removed by the disturbance of air flow.
Description
The utility model relates to a kind of heat transfer fire tube, the heat transfer fire tube of using in particular for boiler heat-transfer.
Heat transfer fire tube inwall in the existing boiler all is a smooth surface, and is very smooth-going during the flame flow piping.Because little with the tube wall contact area, time of contact is short, so heat transfer efficiency is not high.And after long-term the use, along with thickening of inner-walls of duct incrustation.The fire tube inner chamber becomes littler, makes heat transfer area littler, and heat transfer efficiency also becomes lower because of incrustation and the heat transfer area that reduces.
The purpose of this utility model is can increase heat transfer area in order to provide a kind of, prolongs the heat transfer time, and can remove the heat transfer fire tube of inwall incrustation automatically.
Main technical schemes of the present utility model is: the inner wall surface at the heat transfer fire tube is provided with projection, and the corresponding positions of outer wall is equipped with identical shaped pit.
The bulge-structure of heat transfer fire tube inwall makes flue gas produce strong turbulent flow when flowing into the heat transfer fire tube fast. prolonged the heat transfer time on the one hand; The airflow scouring heat transfer fire tube inwall of strong disturbance can effectively be eliminated its surface dirt on the other hand; Simultaneously, bulge-structure can also increase heat transfer area, thereby reaches the purpose that improves heat transfer efficiency.
Fig. 1 is the internal structure schematic diagram of an embodiment of the utility model;
Fig. 2 is an external structure schematic diagram of the present utility model shown in Figure 1.
As shown in Figure 1, on inwall 1 surface of heat transfer fire tube of the present utility model projection is arranged, the shape of cross section of projection is rounded, and the relevant position of outer wall is identical shaped pit 3, can certainly be oval.Adopt smooth-going surfaces such as circle or ellipse can reduce the flow of flue gas resistance, prevent incrustation, can improve heat transfer efficiency equally at some position.
Claims (2)
1, a kind of heat transfer fire tube is characterized in that: there is projection (2) on the inwall of heat transfer fire tube (1) surface, and the relevant position of outer wall is identical shaped pit (3).
2, heat transfer fire tube according to claim 1 is characterized in that: the cross section of projection (2) is circular or oval.
