Abstract
The utility model discloses a fin-tube type air-water heat exchanger. A finned tube is welded between two tube plates, both ends of the two tube plates are provided with an inlet and outlet cylinders which are connected with the tube plates by screw bolts. The utility model has high heat transfer property due to the transversal arranged finned tubes, and the convenience of maintenance and repair can be ensured due to the connection mode of screw bolts.
Description
The utility model relates to the air-water heat exchanger in the heat exchange field, specifically is a kind of fin tube type air-water heat exchanger.
A kind of patent No. 87102392X is arranged at present, and name is called the product of " waste gas boiler with vertical fin horizontal water tube ", and this product adopts flue gas transversal flow heat exchange tube bundle, improved the exothermic coefficient of flue gas, adopt finned tube simultaneously, increased heat transfer area, thereby improved heat exchange performance greatly.But because its cylindrical shell and flue are fixing welding between flue and the finned tube, so in case the weldering at finned tube two meets the generation crack just to be difficult to repair, and the incrustation scale in the finned tube cleans difficulty.
The purpose of this utility model just is to keep the characteristics of patent of invention 87102392X good heat-transfer, overcomes the shortcoming of its maintenance, maintenance difficulty again.
The utility model has kept the principle of patent 87102392X flue gas transversal flow fin heat exchange pipe, and in conjunction with adopting removable cylindrical shell to finish purpose.Its concrete structure is as follows: replace flue with flue, flue gas passes through from flue, finned tube and flow of flue gas direction arranged vertical, its two ends are welded on two tube sheets, this tube sheet constitutes the two side of flue, and two tube sheets connect with the outlet cylindrical shell with the import cylindrical shell respectively with bolt, and cold water at first flows into the import cylindrical shell, flow to the outlet cylindrical shell by the high-temperature flue gas heating again in finned tube, heated water or steam flow out from the outlet cylindrical shell.
The utility model adopts flue gas transversal flow fin heat transfer pipe, the heat transfer efficiency height, adopt Bolt Connection between cylindrical shell and tube sheet, therefore nonvoluntary dismounting when maintenance, very convenient, not only can the incrustation scale in the finned tube manually be cleaned, and repair welding is carried out in the welding between finned tube and tube sheet, change etc.In addition,, thereby saved great deal of steel, and on the barrel-shaped flue in garden, processed boring simply, thereby simplified processing technology again, reduced processing cost owing on flat tube sheet, process the boring ratio owing to the flue that has replaced with flue among the patent 87102392X.
Also in conjunction with the accompanying drawings the utility model is further described below by embodiment.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view among Fig. 1.
Among Fig. 1; 1 is the outlet cylindrical shell, and 2 is tube sheet, the 3rd, and bolt, the 4th, finned tube, the 5th, flue, the 6th, import cylindrical shell.The 7th, weld seam, 8 is water pump.Outlet cylindrical shell 1 and import cylindrical shell 6 connect by bolt 3 with tube sheet 2 respectively; Finned tube 4 two ends respectively with two tube sheets 2 welding, and be with flue gas flow direction and be arranged vertically, two tube sheets 2 constitute the two side of flues 5; The volume of import cylindrical shell 6 is less than the volume of outlet cylindrical shell 1.P among Fig. 1 is the partial enlarged drawing of finned tube 4 and tube sheet 2 connecting portions.
Among Fig. 2,9 is down-comer, and the lower stove fire of relative temperature flows to cylindrical shell 6 along down-comer 9 in the outlet cylindrical shell 1, to constitute the Natural Circulation of stove water.
The utility model both can be used as steam generator, can be used as hot water generator again.
