Abstract
The utility model provides a vortex flow type gas/water heat exchanger. An outer heat exchange pipe which has major diameter and is provided with a smoke gas inlet and a smoke gas outlet at both ends and an inner heat exchange pipe of minor diameter are arranged in parallel and in the same center of circle. Both ends of each of the inner and the outer heat exchange pipes are closed by circular ring plates, and a vortex flow guide plate is welded in circular ring-shaped space between the outer heat exchange pipe and the inner heat exchange pipe. The utility model causes the smoke gas to form vortex flow type motion, and has the advantages of high heat exchange efficiency, simple structure of heat exchange pipes, easy fabrication, material saving, low cost, reliable working and long service life. The utility model can be directly used for the heat recovery of the smoke gas or as a heat exchange member in a water heating furnace, and can also be used for heating or other occasions needing hot water supply.
Description
The utility model relates to a kind of heat exchanger, especially a kind of spiral-flow type air-water heat exchanger that adds hot water with high-temperature gas.
Carry out at present the heat exchanger that heat exchange adopts between high-temperature flue gas that uses and the water plate type heat exchanger, fume tube type heat exchanger, tubular heat exchanger are arranged.Plate type heat exchanger adopts the combinations of many group metal plates, and complex structure, volume is big, cost is high.Fume tube type heat exchanger flue gas carries out heat exchange by the outer water of many cigarette tube and tube, the production cost height, and complex process, smoke pipe is damaged by flue gas corrosion easily, and service life is shorter.Tubular heat exchanger is set up cutoff board usually in heat exchanger tube, make the motion of exhaust gas volumn through-flow shape, and structure is simpler, but heat exchange area is less, and thermal efficiency ratio is lower.
The purpose of this utility model provides a kind of flue gas and hydromining cyclone mode heat exchange, and is simple in structure, easily manufactured, consumptive material is few, long service life, spiral-flow type air-water heat exchanger that heat exchange efficiency is high.
Technical solution adopted in the utility model is: the outer heat exchanger tube (4) of gas approach (2) and exhanst gas outlet (7) is equipped with at large diameter, two ends respectively and the interior heat exchanger tube (5) of minor diameter be arranged in parallel for concentric, inside and outside heat exchanger tube two ends are sealed with circular ring flat-plate (3), and the annular space between outer heat exchanger tube (4) and the interior heat exchanger tube (5) is welded with eddy flow deflector (6).
The utility model forms the spiral-flow type motion with flue gas, the heat exchange efficiency height, and heat exchange tube structure is simple, makes easily, saves material, and is with low cost, reliable operation, service life is long.Can be directly used in the recuperation of heat of flue gas or, be used for heating or other occasions that needs hot water to supply, have vast market demand and good economic benefit as a heat exchange component in the water heater.
Elaborate below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is a kind of embodiment schematic diagram of the utility model.
Fig. 4 is the B-B cutaway view of Fig. 3.
The utility model is by housing (1), gas approach (2), annular plate (3), outer heat exchanger tube (4), interior heat exchanger tube (5), eddy flow deflector (6), exhanst gas outlet (7), delivery port (8), water inlet (9) forms. Wherein large diameter Outer heat exchanger tube (4) is the parallel placement of concentric with the interior heat exchanger tube (5) of minor diameter, and annular plate (3) envelope is adopted at two ends Close, the annular space between two pipes is welded with eddy flow deflector (6), makes this space become spiral flue. Change outward The heat pipe two ends are connected to respectively gas approach (2) and exhanst gas outlet (7). One end of interior heat exchanger tube (5) and water inlet (9) phase Connect. The other end of gas approach (2), exhanst gas outlet (7), delivery port (8), water inlet (9) all causes housing (1) Outward. Flue gas enters space between outer heat exchanger tube (4) and the interior heat exchanger tube (5) from gas approach (2) during use, is revolved The effect of stream deflector (6) is moved in a spiral manner, then outside exhanst gas outlet (7) discharger. Heated cold Water enters interior heat exchanger tube (5) by water inlet (9), is entered in the housing (1) by the other end of interior heat exchanger tube (5), again with outward The heat exchanger tube outer wall carries out heat exchange, is used for the user outward by delivery port (8) carrying device at last.
When the utility model is used for fuel oil (combustion gas) water heater, can replace the smoke pipe heat exchanging part in traditional water heater. Make more simple, the easily manufacturing of device structure, the life-span is long, and it is more reliable to work.
Fig. 3 is a kind of embodiment that is used for water heater of the present utility model.Procapsid (1) is the water heater body of heater, and other increases combustor (10), combustion chamber (11).The installation direction of heat exchanger tube is parallel with combustion chamber (11) in the heat exchanger, and gas approach (2) links to each other with combustion chamber one end, and exhanst gas outlet (7), delivery port (8) and water inlet (9) are all received outside the housing (1).(11) left side sprays into fuel from the combustion chamber by combustor (10) burning generation flame during work, flue gas refluxes outside upper left side, combustion chamber gas approach (2) enters in the heat exchanger tube (4) from the inwall of combustion chamber (11), be subjected to the effect of eddy flow deflector (6), flue gas forms swirling motion between heat exchanger tube (4) and the interior heat exchanger tube (5) outside, carries out heat exchange after exhanst gas outlet (7) discharges out of the furnace with the water of outer heat exchanger tube (4) and interior heat exchanger tube (5) outer wall.After the outer cold water of stove is introduced into interior heat exchanger tube (5) absorption portion flue gas heat from water inlet (9), enter in the body of heater, burned chamber (11) become hot water with the outer wall heating of outer heat exchanger tube (4), discharge out of the furnace from delivery port (8) and use for the user again.
Claims (1)
1, a kind of spiral-flow type air-water heat exchanger, by smoke entrance, intake-outlet, and heat exchanger tube form, it is characterized in that: the outer heat exchanger tube (4) of gas approach (2) and exhanst gas outlet (7) is equipped with at large diameter, two ends respectively and the interior heat exchanger tube (5) of minor diameter be arranged in parallel for concentric, inside and outside heat exchanger tube two ends are sealed with circular ring flat-plate (3), and the annular space between outer heat exchanger tube (4) and the interior heat exchanger tube (5) is welded with eddy flow deflector (6).
