Abstract
The invention relates to a smoke tube of a boiler; the inner wall of a circular-tube smoke tube is provided with equidistant spiral grooves; the cross sections of the spiral grooves are square; a filter member is arranged between each two adjacent spiral grooves; the filter member is a circular-tube metal member; each filter member is provided with a square through hole; the filter member between each two adjacent spiral grooves is arranged irregularly; and each filter member is welded on the inner wall of the smoke tube respectively. Compared with the prior art, the smoke tube disclosed by the invention has advantages of good heat transmission effect, small size, large heat area, good ventilation effect, simple structure and technology, low cost and the like.
Description
Technical field
The present invention relates to a kind of boiler element, relate in particular to a kind of boiler smoke pipe.
Background technology
Boiler is one of important energy conversion, and it is widely used in boats and ships, power station, locomotive and the industrial and mining enterprises, and nowadays, boiler has become the necessaries that heat energy is provided in industrial production and the people's lives.The smoke pipe of conventional boiler adopts single straight pipe type structure, and the smoke pipe of this structure not only heat-transfer effect is relatively poor, and size is large, and consumptive material is many; In addition, can have certain dust impurity in the flue gas, these dust impurity can increase the venting pressure of pipeline, also the heat transfer of smoke pipe produced certain influence, and after the long-term use of smoke pipe, can form crock in the smoke pipe, although can regularly process crock, it is very inconvenient to clear up.
Summary of the invention
The object of the present invention is to provide a kind of not only heat-transfer effect good, size is little, and heating surface area is large, and ventilatory effect is good, and structure, technique are simple, with low cost, long service life, the Boiler smoke tube that is easy to promote the use of.
The present invention mainly includes smoke pipe and filter part, wherein establishes several equidistant helicla flutes on the smoke pipe inwall of circular tube shaped, and this spiral fluted cross section is square; Be provided with several filter parts between described every adjacent two helicla flutes, described filter part is the circular tube shaped metalwork, and establishes several square through holes on each filter part; The irregular setting of filter part between described every adjacent two helicla flutes, each filter part is welded on respectively on the inwall of smoke pipe, and the link position of described filter part and smoke pipe can be a point, can be that a limit also can be a face.
The present invention is when work, because the smoke pipe inwall is established equidistant helicla flute, and establish the filter part between the helicla flute, then flue gas can form irregular eddy flow after entering smoke pipe, in the time of flow of flue gas, the filter part can play certain filtration to flue gas inside dust impurity, so increased the flow process of flue gas, improve the efficient of conducting heat, increased heating surface area; During the inner crock of cleaning smoke pipe, because smoke pipe length of the present invention can be less than the length of traditional smoke pipe, and crock is gathered on the filter part substantially, easy to clean crock not only, and reduce consumable quantity.
Description of drawingsFig. 1 is that master of the present invention looks generalized section.
Fig. 2 is that schematic diagram is looked on a left side of the present invention.
Fig. 3 is the three-dimensional simplified schematic diagram of filter part of the present invention.
The specific embodimentSuch as Fig. 1, Fig. 2 and shown in Figure 3, establish several equidistant helicla flutes 2 on smoke pipe 1 inwall of circular tube shaped, this spiral fluted cross section is square; Be provided with several filter parts 3 between every adjacent two helicla flutes, the filter part is the circular tube shaped metalwork, and establishes several square through holes 4 on each filter part; The irregular setting of filter part between every adjacent two helicla flutes, each filter part is welded on respectively on the inwall of smoke pipe.
Claims (1)
