Abstract
The utility model relates to a helical traveling-wave tube, belonging to the metal pipe kind. The outer wall of the metal pipe is rolled with spiral grooves and the inner wall is provided with spiral fins on the basis of the existing metal pipe; fumes are made to rotate and flow adequately and the temperature is relatively low when the fumes are discharged through the rotary motion of the fumes in the pipe; the fumes all contacts the pipe wall and the heat exchange is sufficient; dust falling in the pipe can be discharged with whirlwind. The utility model has the characteristics of high heat efficiency and low consumption energy.
Description
The utility model belongs to the metal pipe class.
Heat exchange metal tube in the existing heat exchanger as the smoke pipe in the boiler, is tubular shape, and the flue gas of high temperature steadily passes through in pipe fast, and its problem is: one, flue gas flow rate is too unobstructed, and the flue-gas temperature of discharge is higher; Two, flue gas steady direct current in pipe, flue gas and tube wall heat exchange are even inadequately, and the abundant temperature of flue gas heat exchange of close tube wall is the end of than, and the flue gas in center portion can not contact with tube wall, has flowed out with very big heat; Three, the dust that sinks in pipe can not be discharged along with flue gas, and is long-pending more thick more.Above-mentioned reason has seriously influenced the carrying out of heat exchange, causes heat exchange efficiency low, and energy waste is serious.
The purpose of this utility model is: the volute that a kind of rate of heat exchange is high, save the energy is provided.
Technical measures of the present utility model are: based on the metal tube of existing tubular shape, rolling on the outer wall of metal tube have a spiral grooves, and spiral ridge is arranged on inwall.
Volute of the present utility model, owing on the inwall of metal tube, spiral ridge is arranged, make high-temperature flue gas in smoke pipe, be the rotation status motion, cigarette speed rotational flow is suitable, flue gas contacts with tube wall evenly, the dust that sinks in pipe can be discharged with whirlwind, so there is heat exchange abundant, saves the good effect of the energy.
Accompanying drawing is a structural representation of the present utility model.
1 is the metal tube of tubular shape among the figure, rolling on the outer wall of metal tube 1 spiral grooves 2 is arranged by cold rolling, and spiral ridge 3 is arranged on inwall.By the flue gas in the pipe, under the guiding of fin 3, make flue gas be the rotation status motion, its advantage is: one, cigarette speed rotational flow is suitable, and the temperature during discharge is lower; Two, flue gas rotatablely moves, and flue gas and tube wall can both obtain even contact, and heat exchange is abundant; Three, the dust that sinks in pipe can be discharged under the effect of whirlwind thereupon, improves the heat exchange efficiency of smoke pipe.So characteristics that volute has thermal efficiency height, saves the energy.This volute relatively is applicable to 38 to 80 millimeters of diameters, and the groove depth on the volute outer wall is 1 to 4 millimeter.This volute is all more suitable in various tubular heat exchangers.
Claims (2)
1, a kind of volute is made up of the metal tube of tubular shape, it is characterized in that: rolling on the outer wall of metal tube have a spiral grooves, and spiral ridge is arranged on inwall.
2, by the described volute of claim 1, it is characterized in that:
The diameter of a volute is 38 to 80 millimeters;
Groove depth on the b volute outer wall is 1 to 4 millimeter.
