Embodiment Construction

[0013] Such as figure 1 , figure 2 with image 3 As shown, the H-shaped fin tube economizer of the present invention includes a plurality of light pipes 3 arranged in parallel, and the same ends of adjacent light pipes 3 are alternately connected together by means of bent pipes 1, so that all light pipes 3 The inner cavity is connected. Fins 2 are evenly distributed on the longitudinal outer surface of the light pipe 3 , and one surface of the fins 2 is perpendicular to the longitudinal direction of the light pipe 3 . The fins 2 include two long strips 201 with the same length and width, and one long side adjacent to the two long strips 201 is longitudinally and evenly distributed with all the light pipes 3 The cross-sectional shape is adapted, and the number is equal to The light pipes 3 have an equal number of arc-shaped grooves, and the sides of the two long strips 201 with the arc-shaped grooves are welded to all light pipes 3 in an opposite shape, so that the same pla...

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 [0001] The invention relates to an energy-saving device. Specifically, it is a finned tube type coal-saving mechanism installed in the furnace of a coal-fired boiler. Background technique [0002] At present, in the boiler manufacturing industry, in order to save coal and improve the utilization rate of heat energy, most large and medium-sized boilers are equipped with finned tube economizers in the furnace. This kind of finned tube economizer is the most widely used H-type finned tube economizer. The traditional H-shaped finned tube economizer includes a plurality of light pipes arranged in parallel and connected alternately at the same ends, so that the inner cavities of all the light pipes are connected. Spiral fins running through the entire length of the light pipe are welded on the outer surface of the light pipe. Since the fins on the light pipe are spiral, there is a gap between the fins on two adjacent light pipes, so that the heat exchange area o...
