Abstract
The utility model relates to a fin-type water-condensing heat exchanger which is used on a heat-exchange device in petroleum industry, chemical industry, refrigeration industry, etc. The fin-type water-condensing heat exchanger is composed of an outer shell body, tube plates which are arranged on both ends of the inner part of the shell body, an air inlet, an air outlet, a water inlet, a water outlet and a water discharging outlet. A pipe which is connected with the tube plate in the shell body is a finned hot gas pipe, and cooling water which circulates from bottom to top is filled into the inner part of the shell body. After the finned tube is radiated through the cooling water, the water quickly becomes gasand liquid state. The heat exchanging efficiency is high, and large area of the tube heat radiating is replaced by the fins. The casing pressure is reduced, so the thickness of the plate material of the shell body is reduced, and the plate material is saved. The fin-type water-condensing heat exchanger has the advantages of simple manufacturing process and low manufacture cost.
Description
The utility model relates to a kind of fin tube type water condensation heat-exchanger rig, is used for the heat exchanger of industries such as oil, chemical industry, refrigeration.
The heat exchanger of past refrigeration plant is by in the shell body, the gas that the water pipe condenser pipe is outer, and enclosure interior is provided with various heat dissipation pipe, and its complex structure needs a large amount of tubing and sheet material, thereby the manufacturing cost height.
The purpose of this utility model is: a kind of a kind of condensing heat exchanger that relies on the hot gas in the outer cooling water condensation finned tube of housing internally finned tube is provided.This fin has increased area of dissipation, has replaced the area of dissipation of several multitubes, can save a large amount of tubing and sheet material, and technology is simple, and low cost of manufacture is safe and reliable.
The purpose of this utility model can realize by following technical proposals: it is to have carried out improving design on the basis of pressure vessel belonging to originally, and it has shell body or cylinder or square box.According to the place situation can be horizontal or vertical, the two ends, inside of housing (1) have horizontal tube sheet (2), on two tube sheets, be connected with the tracheae (3) of the be condensed water condensation that is arranged type, fin on the external diameter of tracheae (3) is the many fin (4) of expanded joint number, fin (4) can vertically be connected with the external diameter of tracheae (3), also around the connection of part formula, the gas of tracheae (3) is dispersed into heat in the cooling water by the outer many fin (4) of number of tube wall.Because it is finned that the many radiating pieces of this number and tracheae have constituted, the heat of the tracheae water that is cooled is rapidly absorbed, thereby make endotracheal gas liquefy and gaseous state.Air inlet (a) and the following cooled liquid outlet (b) of the other end end socket of heat exchanger are arranged on an end end socket top of heat exchanger, the inlet (c) that has cooling water in the bottom of an end of housing, water is full of and makes the fin heat radiation in the housing, last cooling water is discharged by the top coolant outlet (d) of housing, housing (1) is that flange is connected with end socket, or end socket directly is welded on the tube sheet, and tube sheet is welded on the housing two ends.The bottom is provided with dewatering outlet (e) in order to the usefulness that discharges water winter outside housing.
The utility model compared with prior art, owing to replace cooling tube in the past with the cooling fins pipe, the radiating fin that number is many, the area of dissipation that has replaced pipe, heating pipe is by from bottom to top water quench in the housing, finned tube is cooled off with fast speeds, the very fast quilt of hot gas is lowered the temperature into the form of gas, liquid mixing, improved the efficient of heat exchange, saved a large amount of tubing, the housing in past belongs to the pressure shell body, the thickness of used steel plate is big, and be recirculated water in the housing of the present utility model, no longer be pressurized, so but its sheet material attenuate.Its technology is simple, and low cost of manufacture has improved the security during equipment uses.The cooling because cooling water flows in housing, changed past recirculated cooling water in pipe, through the multilayer baffle, water channel forms and has some setbacks logical and pipe flowing water inequality, cause the inside pipe wall fouling, and influence cooling effect, pipeline stops up easily, needs repairing and brought trouble.

To specifically describe embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, shell body is by the common straightcarbon steel welding fabrication, the circulation of sealing water is arranged, circular cylinder body two welding tube sheet, two tube sheet flange that is threaded, weld end socket on the flange, superincumbent air inlet is arranged on the end socket, giving vent to anger below the end socket of the other end (liquid) mouth several finned tubes in the tubular shell internal arrangement, a head has cooling water intake (C) below housing, have another head that cooling water outlet (D) is arranged on housing, the outside is provided with the dewatering outlet under shell body, is used for winter the water in the housing all being emitted.The finned tube two ends is welded on the tube sheet and communicates with the respective aperture of tube sheet, the fin of finned tube is the vertical gas tube outside, at first be the outside of fin expanded joint at tracheae, can put and be welded on the tracheae, tracheae can adopt aluminum pipe, and fin can adopt antirust aluminium flake, also can adopt the carbon steel thin plate, tracheae also can adopt carbon steel tubing, also adopts zincincation behind the one-tenth finned tube.
As shown in Figure 2, for large heat exchanger, its shell can adopt sheet metal to be welded into square box-type, cold water inlet is arranged below the end, and hot water outlet is arranged above the other end, band two ends tube sheet welding finned tube is equipped with in the inherent underwater of casing, every row's finned tube has steel elbow to be welded to form multilayer on tube sheet to arrange, and the cooling length that has prolonged finned tube has the house steward of welding in the upper end, liquefied gas exported after a cooling was arranged on the house steward, and fin also adopts the fin of expanded joint.
Above-mentioned heat exchanger can be made vertical or horizontal as required.
