Abstract
The invention relates to an H-shaped finned tube economizer, which comprises a plurality of light tubes arranged in parallel, wherein the same ends of the light tubes are alternatively connected together to enable the inner cavities of all light tubes to be communicated; fins are evenly distributed along the longitudinal direction of the light tubes; the sheet surface of each fin is vertical to the longitudinal direction of each light tube. The H-shaped finned tube economizer is characterized in that each fin comprises two long plates with the same length and the same width; arc-shaped grooves are evenly distributed on the longitudinal direction of one long edge of each long plate, wherein the shapes of the arc-shaped grooves are adaptive with the shapes of sections of all light tubes, and the number of the arc-shaped grooves is the same with the number of the light tubes; one edge, which is provide with the arc-shaped grooves, of one long plate and one edge, which is provided with the arc-shaped grooves, of the other long plate are oppositely connected to all light tubes to enable the fins on the same plane on each light tube to be formed into a whole. The economizer has the advantages of large heat exchange area and high heat exchange efficiency and is suitable for a coal-fired boiler.
Description
Technical field
The present invention relates to a kind of energy saver.Specifically, the fin tubular type province coal mechanism in coal-burning boiler burner hearth is mounted in.
Background technology
At present in boiler manfacturing industry, for saving fire coal, improving the utilization rate of heat energy, in the burner hearth of most of large medium-size boiler, being all provided with economizer.This economizer is most widely used with H type economizer.Multiple light pipes that traditional H type economizer comprises in being arranged in parallel, link together in alternately shape between their same one end, make the intracavity inter-connection of all light pipes.The lateral surface of described light pipe is welded with the helical form fin of its overall length through.Because the fin on light pipe is helical form, all leave spacing between the fin on adjacent two light pipes, make the heat exchange area of whole economizer less, heat exchange efficiency is low.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of H type economizer.This economizer, heat exchange area is large, and heat exchange efficiency is high.
The problems referred to above that the present invention will solve are realized by following technical scheme:
H type economizer of the present invention comprises in being arranged in parallel and the multiple light pipes linked together in alternately shape between their same one end, makes the intracavity inter-connection of all light pipes.The longitudinal direction of described light pipe is evenly equipped with fin, and the longitudinal direction of the unilateral and light pipe of described fin is perpendicular.Be characterized in that described fin comprises the two block lengths strip plate all identical with width, the long limit of of two block length battens is longitudinally evenly equipped with and circular groove that quantity with light pipe quantity equal suitable with all light pipe shape of cross sections, described two block length battens with circular groove while be connected on all light pipes in relative shape, the fin on all light pipes on same plane is formed as one.
All there is semicircle wearing bush flue gas windward side on described light pipe, and longitudinal both sides of semicircle wearing bush are evenly equipped with the gap for installation fins adapted with number of fins.
Take such scheme, have the following advantages:
As can be seen from the above scheme, because described fin comprises the two block lengths strip plate all identical with width, the long limit of of two block length battens is longitudinally evenly equipped with and circular groove that quantity with light pipe quantity equal suitable with all light pipe shape of cross sections, described two block length battens with circular groove while connect all on extended surface tube in relative shape, the fin on all light pipes on same plane is formed as one.Because the fin on same plane on all light pipes forms as one, eliminate the spacing of the fin between adjacent light pipe, thus increase the heat exchange area of whole economizer, improve economizer.
Again due to the flue gas windward side on described light pipe being provided with semicircle wearing bush, avoid the wearing and tearing of the granular substance in flue gas to light pipe, thus extend the service life of economizer.
Accompanying drawing explanation
Fig. 1 is H type economizer structural representation of the present invention;
Fig. 2 is the I point enlarged drawing of Fig. 1;
Fig. 3 is the A-A cross-sectional schematic of Fig. 2.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, H type economizer of the present invention comprises the multiple light pipes 3 in being arranged in parallel, and adjacent light pipe 3 links together in replacing shape by bend pipe 1 with between one end, makes the intracavity inter-connection of all light pipes 3.Longitudinal lateral surface of described light pipe 3 is evenly equipped with fin 2, and the longitudinal direction of the unilateral and light pipe 3 of described fin 2 is perpendicular.Described fin 2 comprises the two block lengths strip plate all identical with width 201, one that two block length battens 201 are adjacent long limit is longitudinally evenly equipped with and circular groove that quantity with light pipe 3 quantity equal suitable with all light pipe 3 shape of cross sections, described two block length battens 201 with circular groove while be connected on all light pipes 3 in relative shape, the fin on the same plane on all light pipes 3 is formed as one.Because the fin on the same plane on all light pipes 3 forms as one, eliminate the spacing of the fin between adjacent light pipe 3, increase the heat exchange area of whole economizer, improve the production efficiency of economizer.
For avoiding granular substance in flue gas to the wearing and tearing of light pipe 3, extend the service life of economizer, flue gas windward side on described light pipe 3 being all provided with cross section is semicircular semicircle wearing bush 4, longitudinal both sides of semicircle wearing bush 4 are evenly equipped with the gap adapted with fin 2 quantity, described strip plate 201 being welded on described light pipe 3 by described gap with circular groove being used as fin 2.
