Industrial combustion gas, fuel oil, when coal-burning boiler manufactures and designs, be subjected to heat erosion and stifled ash in order to prevent boiler tail, the standard state exhaust gas temperature generally is not less than 180 ℃, reaches as high as 250 ℃.Be exactly the packaged boiler of market supply, effluent gas temperature is also up to more than 200 ℃, and these valuable heat resourceses do not utilize, and just directly are discharged in atmosphere.Not only cause a large amount of thermal waste, the while is contaminated environment also.In order to improve the thermal efficiency, the waste heat of people during mounting heat exchanger comes recovered flue gas between boiler and flue is used for the heating boiler moisturizing, improves the temperature of injecting the boiler water source, thereby reduces the energy consumption of boiler.Or be used for the domestic hot-water, and improving energy utilization rate, the fuel saving expense reduces production costs, and reduces toxic emission.For this reason, people have researched and developed a large amount of heat exchangers or residual heat using device, have and have much declared patent.But, the problem such as there is complex structure mostly in these products, and heat exchanger volume is large, and manufacturing cost is high, and heat transfer effect is undesirable.
Summary of the invention
The purpose of this utility model is the deficiency that exists for existing boiler afterheat recovering device, provide a kind of can be further simple in structure, volume is little, the boiler afterheat organic efficiency is high, the boiler afterheat heat-exchanger rig of long service life, energy-conserving and environment-protective.
the purpose of this utility model is achieved by the following technical solution: a kind of by heat exchanger plates, heat exchange fin, the boiler afterheat heat-exchanger rig that Inlet and outlet water flange etc. form, be provided with several longitudinal separation plates in the inner chamber of the hollow type heat exchanger plates of aluminium alloy extruded moulding, these space bars are separated into several rectangle water channels with the heat exchanger plates inner chamber, the upper and lower surface of heat exchanger plates outside is evenly equipped with the heat exchange fin that several longitudinal arrangement spacings equate, the heat exchanger plates lateral surface and with the chamber in corresponding space bar be equipped with water inlet near the end, medial surface and with the chamber in corresponding space bar be equipped with delivery port near the end, on the limit of the vertical both sides of heat exchanger plates is stupefied, above it, dual-side is stupefied is provided with interior breach, following dual-side is stupefied to be provided with and top corresponding outer breach.
Some heat exchanger plates by under from upper superimposed arrangement, below the heat exchanger plates of top, the stupefied outer breach of dual-side matches with interior breach on dual-side above the heat exchanger plates of bottom is stupefied, mutually intert between heat exchange fin on two heat exchanger plates of up and down, the gap between heat exchange fin consists of several heat transfer flues; After some heat exchanger plates assemblings, water inlet is in-line and is arranged in parallel, and is positioned at water-in flange, and the delivery port of opposite side also is in-line and is arranged in parallel, and is positioned at water-output flange.
Water-in flange is connected with the boiler blow-down water case by pipeline etc., and water-output flange is connected with boiler or warm washing water's case by pipeline etc.
The gas approach flange is connected with boiler smoke outlet, and the exhanst gas outlet flange is connected with the air-introduced machine import.
When boiler high temperature waste heat flue gas enters the heat transfer flue that is made of heat exchange fin between heat exchanger plates and heat exchanger plates through the chimney intake flange, its heat heats water in the heat exchanger plates inner chamber by heat exchange fin, then enters chimney by facilities such as flue outlet flanges under the effect of air-introduced machine emptying.Hot water after intensification enters boiler or boiler through water-output flange, pipeline etc. under the effect of water pump, as boiler feed water or life heating water.
The beneficial effects of the utility model are that the heat exchanger plates by aluminium alloy extruded moulding is the boiler afterheat heat-exchanger rig that formant is assembled into through processing, its simple in structure, easy processing, volume are little, lightweight, the heat conduction is fast, good effect of heat exchange, utilization rate of waste heat are high, save the energy, can form batch production.
