Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
The structure of the finned tube waste-heat recoverer that the utility model provides as depicted in figs. 1 and 2, comprise by header board 13, side plate 6, rear plate 16, the housing that top board 4 and base plate 8 are welded to form, the heat pipe that some groups pass side plate 6 two ends is provided with in housing, often organize heat pipe and comprise the finned tube 2 that many ND steel passing side plate 6 arranging from top to bottom make, it is coiled pipe structure that adjacent fins pipe 2 passes through elbow 5 connecting overall successively, elbow 5 is positioned at hull outside, the end of the finned tube 2 of many groups heat pipe bottommost is connected with into water distributing pipe 14 jointly, the pipe end of water inlet distributing pipe 14 is provided with water inlet 10, the end of the finned tube 2 of many groups heat pipe top is connected with water outlet collector 11 jointly, the end of water outlet collector 11 is provided with delivery port 1, header board 13, rear plate 16 is respectively arranged with into mouth 15 and outlet flue 12.
The bottom of housing is provided with discharge opening 9.
Base plate 8 is obliquely installed, and discharge opening 9 is positioned at the least significant end of base plate 8, and one end 8mm-10mm lower than the other end of discharge opening 9 is housed.
Enter mouth 15 and outlet flue 12 is horn-like, its big opening end is all arranged towards enclosure interior.
The lower end of housing is provided with supporting leg 7, and the height of supporting leg 7 can adjust according to actual conditions during installation.
Top board 4 is provided with hanger 3, lifting during convenient installation.
Finned tube waste-heat recoverer of the present utility model adopts fin tube structure, finned tube 2 is made up of light pipe and fin, by fin with ratio-frequency welding spiral welded on light pipe, therefore its convection heating surface amasss as fin surface and light pipe surface sum, heat exchange area is 6-10 times of light pipe, strengthens heat exchange efficiency; Thus, under the condition that heat exchange amount is identical, greatly reduce the volume of finned tube waste-heat recoverer; Because the flue gas flowed through in waste-heat recoverer is low-temperature flue gas, a large amount of condensed water can be produced after heat release in finned tube waste-heat recoverer, after sour gas in flue gas incorporates condensed water, meeting causes corrosion to a certain degree to finned tube 2, have impact on the service life of finned tube waste-heat recoverer, thus light pipe and fin material all adopt corrosion-resistant ND steel, reduce because cold end corrosion is on the impact in finned tube waste-heat recoverer life-span.
Finned tube waste-heat recoverer operation principle of the present utility model is, the flue gas of higher temperature enters enclosure interior by entering mouth 15, transversal flow finned tube 2, the water at low temperature passed in finned tube 2 with water inlet distributing pipe 14 carries out heat convection, low-temperature flue gas after heat exchange is flowed out by outlet flue 12 again, enter mouth 15 and outlet flue 12 is designed to flared structure and its big opening end is arranged towards enclosure interior, flue gas journey divergent shape is entered, avoids the impact of washing away uneven heat exchanging efficiency; Water at low temperature enters into water distributing pipe 14 by water inlet 10, entered again in each group of heat pipe be made up of finned tube 2 and elbow 5 by water inlet distributing pipe 14, carry out heat convection with flue gas, after absorbing heat, the water of higher temperature flows into water outlet collector 11, then is flowed out by delivery port 1.
Finned tube waste-heat recoverer of the present utility model organizes heat pipe by arranging in enclosure interior more, under the prerequisite not increasing volume, the heat exchange area of heat exchanger tube is effectively increased by multiple finned tube, improve heat exchange efficiency, absorb the heat of low-temperature flue gas, reduce flue gas loss, save fuel energy, and the corrosion resistant ND steel of finned tube material selection, extend the service life of device, cost-saving.
