Abstract
The utility model relates to an air cooler, and particularly relates to a dry tube bundle device of an evaporative air cooler with a protective sleeve at a pipe end. The dry tube bundle device is characterized in that a tube plate arranged inside a pipe box is combined and connected with the pipe end of a fin tube with the protective sleeve into a whole via an expanded and welded tube joint; one end of the pipe box is provided with a connecting pipe and the other end of the pipe box is provided with a connecting nozzle to form a tube bundle so as to form a tube cavity body communicated with a tube cavity; a rolled aluminum fin is connected outside a carbon steel base tube; and a stainless steel protective sleeve is sleeved at the end part to form a thermometal rolled aluminum fin tube with the stainless steel protective sleeve. The dry tube bundle device has the advantages that the protective sleeve at the end part of the fin tube separates the carbon steel base tube from acid wet air, prevents the bared carbon steel base tube from being corroded, is simple in structure and low in cost, saves energy sources, and is an environment-friendly product for saving energy and reducing emission.
Description
Technical field: the utility model relates to air cooler, specifically a kind of evaporation air cooler main bundle device of pipe end band protective sleeve.
Background technology: in oil, chemical field, air cooler is to rely on the blower fan forced ventilation to make the equipment that in air and heat dissipation element finned tube, the process fluid heat exchange reduces the process fluid temperature.
Though evaporative air-cooling main bundle does not directly contact with shower water, but during evaporative air-cooling main Shu Yizhi is in humid air in evaporative air-cooling apparatus running, and often in the air of refinery more or less all contain the acidic materials such as sulfur dioxide, exposed like this carbon steel finned tube parent tube outer surface in the acidic wet air very soon corrosion rot, some individual device is used and was just had to change for this reason new equipment less than 1 year.The way one that in the past addressed this problem is that heat exchanger tube adopts stainless steel tube, and the material that this sample need not be upgraded is forced to upgrading, has greatly improved the cost of equipment; The 2nd, the aluminum casing lengthening with rolled fin extends in tube sheet, and there is the gap in the precision problem owing to making, can not tackle the problem at its root, and the engineering effect is bad.
Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, corrosion-resistant, the evaporation air cooler main bundle device of convenient processing and manufacture, pipe end band protective sleeve with low cost.The purpose of this utility model is achieved in that it comprises flange, adapter, bobbin carriage, tube chamber, protective sleeve, carbon steel parent tube, fin, connects mouth, tube sheet, plate; it is characterized in that: the tube sheet that is provided with in described bobbin carriage is combined through expanded and welded tube joint with described finned tube pipe end with protective sleeve and is connected as one, and an end of described bobbin carriage is provided with described adapter, the other end and is provided with and connects mouth and form the tube chamber that tube bank, formation communicate with tube chamber.Described carbon steel parent tube is externally connected with rolling aluminium fin, and the end cover has the stainless steel protection cover, consists of the bi-metal rolling aluminum finned tube with the stainless steel protection cover.The utility model has the advantages that: the protective sleeve of finned tube end is kept apart carbon steel parent tube and acid humid air, has avoided exposed carbon steel parent tube to be corroded.Simple in structure, with low cost, save the energy, be the environment-friendly products of energy-saving and emission-reduction.
Description of drawings: Fig. 1 is the utility model structural principle generalized section; Fig. 2 is the utility model tube sheet and protective sleeve, carbon steel parent tube, fin syndeton principle generalized section; Fig. 3 is the utility model stainless steel protection nested structure principle generalized section.
The specific embodiment: the evaporation air cooler main bundle device of pipe end band protective sleeve; it comprises flange 1, adapter 2, bobbin carriage 3, tube chamber 4, protective sleeve 5, carbon steel parent tube 6, fin 7, connects mouth 8, tube sheet 9, plate 10; it is characterized in that: the tube sheet 9 that is provided with in described bobbin carriage 3 be combined through expanded and welded tube joint with described fin 7 pipe pipe ends with protective sleeve and is connected as one, and an end of described bobbin carriage 3 is provided with described adapter 2, the other end and is provided with and connects the tube chamber that mouth 8 formation tube banks, formation communicate with tube chamber 4.Described carbon steel parent tube 6 is externally connected with rolling aluminium fin 7, and the end cover has stainless steel protection cover 5, consists of the bi-metal rolling aluminum finned tube with the stainless steel protection cover.It comprises flange 1, adapter 2, bobbin carriage 3, tube chamber 4, stainless steel protection sleeve pipe 5, carbon steel parent tube 6, fin 7, connects mouth 8, tube sheet 9, plate 10.The tube sheet 9 that is provided with in bobbin carriage 3 is combined through expanded and welded tube joint and is connected as one with protective sleeve 5, carbon steel parent tube 6 (pipe end), and an end of bobbin carriage 3 is provided with and takes over 2, the other end is provided with and connects mouth 8 and form the tube chamber that tube banks, formation communicate with tube chamber 4.Carbon steel parent tube 6 is externally connected with fin 7, and in carbon steel parent tube 6 ends, carbon steel parent tube 6 and fin 7 (end aluminum casing) are externally connected with stainless steel protection cover 5, consists of band protective sleeve finned tube.The utility model band protective sleeve finned tube is through being rolled into aluminium fin 7 by the outer aluminum pipe of carbon steel parent tube 6; reserve the thick aluminum casing 7 that is connected as a single entity with the aluminium fin of sufficiently long carbon steel parent tube and 1mm; by interference fit, Fig. 3 is shown that the stainless steel protection cover is enclosed within on the carbon steel and aluminum casing of finned tube end; during assembling, cover is had finned tube (the carbon steel parent tube 6+ fin 7) end of stainless steel protection cover 5 and tube sheet 9 expanded and welded tube joints in bobbin carriage 3 to be connected as a single entity, stainless steel protection cover 5 does not participate in the welding of carbon steel parent tube 6 and tube sheet 9 simultaneously.Bobbin carriage is made through assembly welding by tube sheet 9 and other carbon steel sheet 10, flange 1, take over 2, connect mouth 8 with bobbin carriage 3 by soldering group formation tube chamber welded together.In band protective sleeve 5 finned tubes (6+7) and bobbin carriage 3, tube sheet 9 is connected by expanded and welded tube joint, adds the common dried air coolings of evaporation that form of the steel constructions such as crossbeam, side plate part and restrains.Bobbin carriage, adapter, flange, carbon steel heat exchanger tube, protective sleeve, fin and steel construction have formed the dried air cooling pipe bundle device of evaporation jointly.The dry air cooling pipe bundle device of this applicable Novel steam can safe operation in acid humid air; the stainless steel protection cover make the carbon steel parent tube of finned tube end and the acidic wet air isolated; avoid corrosion, extended the service life of equipment, also avoided unnecessary material upgrading.
