The specific embodiment
Below in conjunction with embodiment the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Fig. 1 shows the according to an embodiment of the invention structural representation of low temperature exhaust heat retracting device.An embodiment with reference to a kind of low temperature exhaust heat retracting device shown in Figure 1, comprise housing (104), be provided with many spaced heat pipes (101) in the described housing (104), utilize the heat transfer property of heat pipe (101), can guarantee at low temperatures safe operation, to raise the efficiency and energy efficiency; Described many spaced heat pipes (101) can be divided into according to the running temperature of flue gas high, medium and low warm pipe; Be provided with dividing plate (102) in the middle of the housing (104), it is divided into fume side (105) and carbonated drink side (106) two parts, fume side is provided with a smoke inlet (107), an exhanst gas outlet (108), a steam blowing mouth (109), a drain port (110), steam trap connection (116) is set in hydrophobic exit, become hydrophobic passing through after making the water vapour cooling that contains in the flue gas, and flue gas must not pass through.In carbonated drink side (106), in the heating exit Shutter Steam Separator (103) is installed, can guarantee to improve the quality of steam, and be provided with water dispensing apparatus (117) at cooling water inlet place, can guarantee the homogeneous heating of intaking, be provided with on the described carbonated drink side (106) cooling water inlet (111), steam (vapor) outlet or hot water outlet (112), one clean entrance (113), a washing outlet (114), a vacuum orifice (115).
Wherein the quantity of smoke inlet (107), exhanst gas outlet (108), steam blowing mouth (109), drain port (110), cooling water inlet (111), steam (vapor) outlet or hot water outlet (112), cleaning entrance (113), washing outlet (114) and vacuum orifice (115) is not limit, can be for a plurality of.
The caliber of described every heat pipe (101) is 0～100 millimeter, and length is 500～20000 millimeters, and the adjacent holes back gauge is 100～800 millimeters.Another embodiment can be, the caliber of heat pipe (101) is 50 millimeters, and length is 10000 millimeters, and the adjacent holes back gauge is 500 millimeters.
In order to guarantee heat-transfer effect, require water velocity in the carbonated drink side less than 0.5m/s.
As shown in Figure 1, flue gas is entered by left side smoke inlet (107), flue gas after entering begins to wash away heat pipe (101), heat pipe (101) is activated and just automatically heat is conducted to upper part, at this moment heat pipe (101) bringing-up section heat absorption, flue gas temperature behind heat pipe (101) descends gradually, because drop in temperature, the water vapour that flue gas contains begins to condense, it is hydrophobic through being discharged by drain port (110) after steam trap connection (116), and heat is absorbed by heat pipe (101) and conducts to carbonated drink side (106); When heat pipe (101) when bringing-up section is heated, the rapid carburation by evaporation of liquid in the capillary, steam flows to condensation segment under small pressure reduction, under the cooling of seawater, releases heat, regelation becomes liquid, and liquid flows back to bringing-up section along porous material by the effect of capillary force again, so circulation is more than, and heat reaches an other end by heat pipe (101) one ends.This circulation is carried out fast, and heat can be come by continuously conduction.Heat pipe (101) is in the process that realizes this transfer of heat, thus cooling water heat absorption evaporation.
Former water is entered by cooling water inlet (111), and under the uniform distribution of water dispensing apparatus (117), spray uniformly on the heat pipe (101), at this moment heat pipe condenser section is through heat release, seawater with the heat transferred atomizing, make its heating vaporization, during by Shutter Steam Separator (103), because vapour, current direction is orthogonal, centrifugal force when steam flow is turned is separated water droplet, stick to the very thin moisture film of the upper formation of Shutter Steam Separator (103), slowly flow downward by gravity, form larger water droplet in the lower end of Shutter Steam Separator (103) and fall, thereby carry out carbonated drink separation, discharged by steam (vapor) outlet or hot water outlet (112) at last.
" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", etc., refer to specific features, structure or the characteristics described in conjunction with this embodiment and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiment this feature, structure or characteristics also fall within the scope of the invention.
Although invention has been described with reference to a plurality of explanatory embodiment of the present invention here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and embodiment will drop within the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes also will be obvious.
