Abstract

The utility model provides a threaded flue type waste heat boiler which comprises a boiler body, wherein a fume inlet is formed in one end of the boiler body; a fume outlet is formed in the other end of the boiler body; a flue penetrates through the boiler body; and rifled tube is used as the flue. The threaded flue type waste heat boiler has the advantages that the inner wall of the flue adopts a thread structure, the contact area between fume and the flue can be greatly increased, and the turbulent motion of the fume in the flue is enhanced, so that a heat transfer effect is obviously improved, and resistance is not too high.

Description

Threaded flue formula waste heat boiler
Technical field
The utility model relates to a kind of waste heat boiler, relates in particular to a kind of threaded flue formula waste heat boiler.
Background technology
The fume tube type waste heat boiler is that the high-temperature flue gas of getting rid of when the user is produced carries out UTILIZATION OF VESIDUAL HEAT IN.High-temperature flue gas can produce hot water by corresponding waste heat boiler or steam is supplied with other workshop sections' uses, has improved the utilization rate of the heat of fuel combustion release widely.The smoke pipe that uses adopts drum type brake at present, and inwall is a smooth surface, and the turbulence of flue gas in smoke pipe is not enough, and heat-transfer effect is not good.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, provides a kind of heat-transfer effect good threaded flue formula waste heat boiler.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of threaded flue formula waste heat boiler comprises body of heater, end at body of heater is provided with gas approach, the other end at body of heater is provided with exhanst gas outlet, and smoke pipe connects body of heater, and smoke pipe is a riffled tube.
The utility model optimized technical scheme is smoke pipe pitch 35mm, screw thread convex height 2mm.
The utility model optimized technical scheme is to be provided with tube sheet at the gas approach place.
The utility model optimized technical scheme is on the described tube sheet through hole to be arranged.
Compared with prior art, this threaded flue formula waste heat boiler, smoke pipe inwall are helicitic texture, can increase the contact area of flue gas and smoke pipe greatly, strengthen the turbulence of flue gas in smoke pipe, thereby significantly improve heat-transfer effect, and unlikely again resistance is too big.And the gas approach place is provided with tube sheet, and tube sheet is provided with through hole, makes the smoke pipe that connects body of heater to fix by the through hole on the tube sheet, ensures effective utilization of heat.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the profile of smoke pipe in the utility model.
Fig. 3 is the profile of tube sheet in the utility model.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
The specific embodiment
Embodiment 1
Referring to Fig. 1, Fig. 2 and Fig. 3, this threaded flue formula waste heat boiler comprises body of heater 1, is provided with gas approach 2 at an end of body of heater 1, is provided with exhanst gas outlet 3 at the other end of body of heater 1, and smoke pipe 4 connects bodies of heater 1, and smoke pipe 4 is riffled tubes.Smoke pipe 4 pitch 35mm, screw thread convex height 2mm.2 places are provided with tube sheet 5 at gas approach.On the described tube sheet 5 through hole 6 is arranged.
Compared with prior art, this threaded flue formula waste heat boiler, smoke pipe inwall are helicitic texture, can increase the contact area of flue gas and smoke pipe greatly, strengthen the turbulence of flue gas in smoke pipe, thereby significantly improve heat-transfer effect, unlikely again resistance is too big, the preferred pitch 35mm of smoke pipe, screw thread convex height 2mm.And the gas approach place is provided with tube sheet, and tube sheet is provided with through hole, makes the smoke pipe that connects body of heater to fix by the through hole on the tube sheet, ensures effective utilization of heat.
