Abstract
The utility model belongs to the class of the heat exchanger, particularly a heat exchanger which makes use of the residual heat in a gas flue to heat the wind in the wind pipe. The heat-exchanger uses a flue gas exhaust pipe as a hot air pipe, and uses the wind pipe of the blower as a cold air pipe, a heat pipe is arranged between the two air pipes to conduct thermal transmission, the two air pipes are fixed and connected as an integral with a bent pipe, and a dust cleaning port and a dust falling port are arranged on the hot air pipe. By adopting the heat pipe as the thermal transmission element, the thermal efficiency conduction ratio of the utility model is 5-10 times higher than that of the tube array type heat exchangers. The utility model has small volume, is convenient to clean dust, and can be used for various boilers.
Description
The utility model belongs to the heat exchanger class, specifically a kind of heat exchanger that utilizes the waste heat in the flue that the wind in the ajutage is heated.
Utilize the waste heat in the flue that preheating is carried out in the air-supply of air blast at present, generally adopt shell and tube or cast iron type heat exchanger.Between tubular heat exchanger pipe and the pipe, be non-removable integral body between pipe and the bobbin carriage, constitute a throttle orifice, when the high-temperature flue gas that has a waste heat passes through from tubular heat exchanger, flue gas is obstructed herein, dust in the flue gas is deposited in the interchanger easily, use flue to be blocked by dust for a long time, and this kind heat exchanger is non-disconnectable integral body, deashing is difficulty relatively, and heat exchanger effectiveness reduces.The heat exchanger effectiveness of cast iron type heat exchanger is also lower, can not reach making full use of of waste heat in the flue.
The purpose of this utility model is to provide a kind of heat-pipe elements that utilizes high as the heat exchanger effectiveness of heat transfer element, and is easy to clear up the angie type heat exchange of heat pipe of dust stratification.
The utility model is to realize like this, with smoke discharging pipe as hot ventilation duct (5), by the pipeline of air blast air-supply as cool air hose (1), one end of heat pipe (2) inserted the other end inserts in the cold ventilation duct (1) in the hot ventilation duct (5), its technical essential is fixedly to be connected as a single entity through bend pipe (3) between hot siphunculus (5) and the cold ventilation duct (1), and the mid portion of heat pipe (2) is arranged in bend pipe (3); The upper surface of its hot ventilation duct (5) is provided with a cleaning door with cover (8), and the lower surface is provided with an ash port with cover (7).So just constituted the said heat exchanger of the utility model, its operation principle is the flue gas during by its hot ventilation duct (5) that has a waste heat, heat pipe (2) in the hot ventilation duct (5) is heated, by heat pipe (2) heat being delivered to cold ventilation duct (1) again will be by the air heat in the cool air hose (1), send into air themperature, the ignition temperature of burner hearth and the thermal efficiency of boiler in the burner hearth with raising.After using a period of time, in order to remove the dust stratification in the warm-air pipe (5), as long as the lid of cleaning door (8) and ash port (7) is opened, just can easily the dust stratification in the hot ventilation duct (5) be removed, with resistance that reduces flue gas and the heat exchanger effectiveness that keeps heat pipe (2).
In order to reduce the heat radiation loss of the mid portion of heat pipe (2) in bend pipe (3), heat pipe (2) in bend pipe (3) can be filled heat-insulating material (4) on every side, to stop heat pipe (2) in air, to dispel the heat, improve the utilization rate of heat energy in the part of bend pipe (3).Heat-insulating material (4) also can only paste one deck on the inwall of bend pipe (3), as long as guarantee that heat is not shed through bend pipe (3).
For improve heat pipe (2) hot ventilation duct (5) heat absorption rate and the radiating efficiency of heat pipe (2) in cold ventilation duct (5); Heat pipe (2) is equipped with fin (9) at hot ventilation duct (5) and the part in cold ventilation duct (1), and fin (9) can adopt carbon steel, copper or the aluminium etc. of high conduction efficient.
In order to prolong the cleaning cycle in the hot ventilation duct (5), prevent that dust stratification is deposited in the hot siphunculus (5), the obstruct smoke passage, ash port (7) in the lower surface of hot ventilation duct (5) is located a fixedly connected ash dropping hopper (6), ash dropping hopper (6) is a funnel, the lid of its ash port (7) covers on the mouth of the lower end of ash dropping hopper (6), and a part of in use dust stratification just can directly fall into ash dropping hopper (6), has so just reduced the resistance of hot ventilation duct (5) to flue gas.During dust stratification in cleaning hot ventilation duct (5), the dust stratification in the hot ventilation duct (5) arrive ash dropping hopper (6) at first clearly, and then concentrate and remove, promptly convenient, stir up a cloud of dust in the time of can avoiding the dust whereabouts again, cause environmental pollution.
Fig. 1 is a structure principle chart of the present utility model,
Fig. 2 is the left view of Fig. 1;
Among the figure, 1, cold ventilation duct; 2, heat pipe; 3, bend pipe; 4, heat-insulating material; 5, hot ventilation duct; 6, ash dropping hopper; 7, ash port; 8, cleaning door; 9, fin.
Because the utility model adopts the heat pipe of the title with " superconduction hot body " as heat conducting element, heat-conducting efficiency is higher 5～10 times than tubular heat exchanger, can improve widely the wind pushing temperature of boiler. Little, the compact conformation of this heat exchanger volume, and be easy to deashing, can be widely used in various boilers, to improve fire box temperature, to reduce exhaust gas temperature, improve the thermal efficiency of boiler.
