Abstract
The utility model discloses a jacket bucket type waste flue gas heat exchanger, which is characterized in that an oval-shaped barrel of a water soluble device is welded on the outer portion of an oval-shaped barrel of a flue gas channel, two ends of the oval-shaped barrel of the water soluble device is closed to form a closed cavity, a plurality of heat conduction pipes are welded in the oval-shaped barrel of the flue gas channel, one ends of the plurality of heat conduction pipes are projected into the oval-shaped barrel of the water soluble device, and the oval-shaped barrel of the flue gas channel is connected with the flue gas channel. By means of the above configuration, the utility model is capable of increasing the temperature of the flue gas from 235 DEG C to 135 DEG C nearly, if the reclaimed exhaust heat is used to increase the temperature of the feed water of a boiler, the temperature of the feed water is higher than that of the heat exchanger of a box body by 3-5 DEG C, which improves energy-saving effect greatly.
Description
Technical field
The utility model relates to the device of a kind of boiler kiln with the useless flue gas heat energy of recovery, definite a kind of simple, that the heat recovery face is big a kind of heat exchanger of making of saying so.
Background technology
The useless flue gas of various kilns, boiler emission up to 235 ℃ about, not only wasted heat energy, weather is warmed, now the casing vacuum heat-pipe heat exchanger that adopts has and makes the shortcoming that recruitment is many, have only local heating, benefit does not reach higher limit.
Summary of the invention
The purpose of this utility model is that a kind of useless flue gas heat exchange device of the nested simple, that the heat recovery face is big of making is provided.
The technical scheme that the utility model proposes is: the oval bucket of water-soluble device is welded on the outside of the oval bucket of gas flue, the closed at both ends of the oval bucket of water-soluble device forms an enclosed cavity, many heat pipes are welded on the interior also end of the oval bucket of gas flue and stretch in the oval bucket of water-soluble device, and gas flue is connected with exhaust gases passes for oval barrel.
Water-soluble device is partly oval for long bucket, and gas flue is also oval for long bucket, and two oval buckets are nested, and in the oval bucket of gas flue upper bore, it is some to put heat pipe, and the ground on the right that keeps left can slightly tilt, and water-soluble device is sealed at both ends.The oval casing of gas flue can be described as the four sides and is heated in big oval water-soluble device, and used heat is delivered in the preheating water fully, and the design can increase by 30% heat transfer efficiency than casing.
The utility model can make the waste heat of flue gas mouth drop to about 135 ℃ for about 235 ℃, if the used heat that reclaims is used for increasing the temperature of boiler feedwater, the high 3-5 of the heat exchanger of comparable casing ℃, has improved energy-saving effect greatly.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram
Among the figure 1, the oval bucket 2 of water-soluble device, the oval bucket 3 of gas flue, heat pipe 4, water 5, exhaust gases passes
The specific embodiment
As shown in Figure 1, the oval bucket 1 of water-soluble device is welded on the outside of the oval bucket 2 of gas flue, the closed at both ends of the oval bucket 1 of water-soluble device forms an enclosed cavity, and many heat pipes 3 are welded in the oval bucket 2 of gas flue and ends stretch in the oval bucket 1 of water-soluble device, and the oval bucket of gas flue 2 is connected with exhaust gases passes 5.It is flue that the oval bucket of gas flue is removed at two ends, front and back are stayed outside the square opening, all the other whole welded closure, all be water around the flue floss hole like this, be beneficial to heat transmission, flue is by heat pipe moment heat conduction, the principle of two ends isothermal, the heat of useless flue gas is delivered in the big oval inner bucket water,, softening pond water temperature is increased to more than 70 ℃ through circulation.
