Abstract
The utility model discloses a powerful environment protection oven remaining heat withdrawing device, in particular to a remaining heat withdrawing device equipped between the high temperature flue inlet and the chimney. The withdrawing device comprises a water storage tank and a plurality of the heating exchange brass tubes inside the tank. On the water storage tank is equipped with a cold water inlet and a hot water outlet. The heating exchange pipes is made of a plurality of heating exchange brass pipe, the upper of the heating brass pipe is equipped inside the water storage tank, the lower is equipped inside the oven flue passage on the bottom plate of the tank, the flue passage is a high temperature smoke dispersing area, the hot flue passes through the gap between the heating exchange pipes and flows into the low temperature flue area and exhausts out from the chimney. In the lower of the heating exchange brass pipe is equipped with water medium, the upper is vacuum chamber, the water medium steam of the preheated water enclosed by the heat remaining flue passage ascends into the vacuum chamber, the heat is induced to the cold water in the storage tank, and then the heating exchange is finished. The utility model is applicable to variable fuels oven.
Description
Technical field
The utility model relates to a kind of high-efficiency environment-friendly boiler waste-heat recovery device.
Background technology
In industrial and agricultural production and daily life, the application of boiler has been very extensive, at present in the boiler of using, existing major defect is that the thermal efficiency is low, and the environmental pollution of chimney is serious, and the chimney of boiler is because the temperature height of smoke evacuation, flue dust is many, has become the problem that people are sick of.This has not only wasted the energy, and has influenced environmentally-friendly sanitary and attractive in appearance.
Summary of the invention
The purpose of this utility model is at the existing problem of above-mentioned boiler, and the high-efficiency environment-friendly boiler waste-heat recovery device of the waste heat recovery of a kind of energy, energy savings is provided
The side achieve the above object, the utility model has mainly adopted following technical scheme to realize.The utility model mainly is to be provided with waste-heat recovery device between the high-temperature flue gas entry of boiler and the chimney, described waste-heat recovery device is made up of water storage tank and the set of heat exchange tubes be located in the water storage tank, water storage tank is provided with cold water inlet and hot water outlet, set of heat exchange tubes is made up of some heat exchange copper tubes, the top of heat exchange copper tube is located in the water storage tank, the bottom is located in the boiler flue of water storage tank floor below, flue is the high-temperature flue gas radiating area, and hot cigarette flow into the low-temperature flue gas outlet by the space between the heat exchange copper tube and discharges through chimney.Bottom in the heat exchange copper tube is provided with aqueous medium, then is vacuum chamber at an upper portion thereof, and the steam of aqueous medium that advanced the preheating of flue residue heat will rise to vacuum chamber, and heat is delivered in the cold water in the water storage tank, finishes heat energy conversion.
The utility model compared with prior art has following obvious advantage and innovation.(1) heat transfer rate is fast, the efficient height.Because the water quality in the heat exchanger tube is to exist under the conditions of air not having, when temperature remained unchanged, because vaporization produces steam on the water quality liquid level, steam at this moment was tending towards a stationary value, is exactly the saturated vapour pressure under this temperature.When high-temperature flue gas was flowed through the heat exchanger tube bottom, temperature raise in the pipe, and saturated pressure constantly rises, and liquid water constantly evaporates, and it constantly absorbs heat from the high-temperature region of heat exchanger tube bottom, this time temperature new saturated.Because heat rises, outer wall is cooling liquid or refrigerating gas, thermal power transfer, and the gas temperature of contact heat-exchanging pipe upper inside wall reduces rapidly, condenses into the globule, flows down along tube wall and enters the high-temperature region, and heat is transmitted in so continuous circulation.(2) flue gas runs into heat pipe cooling, and temperature reduces, volume-diminished, and flow velocity slows down, and a large amount of dusts drop in the pond in cigarette ash road of bottom in the flue gas, have reduced the pollution to environment.(3) because this heat exchanger tube is vertical installation, the bottom has water to flow again, so cigarette ash is difficult for stopping up, is convenient to deashing.(4) because the temperature of flue gas is very low, can also substitute the iron pipe chimney, save the cost of chimney, prolong the life-span of using with the plastic tube chimney.(5) this heat-exchanger rig can be used for boiler flue gas cool-down, heat recovery, the preheating of air that also can carry out the burning of boiler.
The utility model is applicable to various fuel boilers.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model overall structure cut-away view.
The specific embodiment
As shown in the figure, the utility model mainly is to be provided with waste-heat recovery device 10 between the high-temperature flue gas entry 4 of boiler and the chimney 7, described waste-heat recovery device 10 is made up of water storage tank 2 and the set of heat exchange tubes 11 be located in the water storage tank 2, water storage tank 2 is provided with cold water inlet 1 and hot water outlet 3, set of heat exchange tubes 11 is made up of some heat exchange copper tubes 12, the top of heat exchange copper tube 12 is located in the water storage tank 2, the bottom is located in the boiler flue 5 of water storage tank floor below, boiler flue 5 is the high-temperature flue gas radiating area, and hot cigarette flow into low-temperature flue gas outlet 6 by the space between the heat exchange copper tube 12 and discharges through chimney 7.Bottoms in the heat exchange copper tube 12 are provided with aqueous medium 9, then are vacuum chambers 8 at an upper portion thereof, and the steam of aqueous medium 9 that advanced the preheating of boiler flue 5 waste heats will rise to vacuum chamber 8, and heat is delivered in the cold water in the water storage tank 2, finish heat energy conversion.
The utility model is applicable to various fuel boilers.
