Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:
A kind of flue gas heat-exchange unit, comprise: housing 1, multiple heat exchanger fin group 2, clearing apparatus, feed tube 4 and drain pipe 5, described heat exchanger fin group 2 is formed by stacking by two heat exchanger plates 21, hollow cavity 22 is provided with between described two heat exchanger plates 21, the inside being fixedly connected on described housing 1 that described multiple heat exchanger fin group 2 parallels successively, interval 23 is provided with between two adjacent heat exchanger fin groups 2, described clearing apparatus comprises cleaning support 31 and multiple brush sweeper 32, described brush sweeper 32 is fixed on described cleaning support 31, multiple brush sweeper 32 lays respectively in the interval 23 between described two connected heat exchanger fin groups 2, described cleaning support 31 drives described brush sweeper 32 to move in the inside at described interval 23, described feed tube 4 and drain pipe 5 are connected with described heat exchanger fin group 2 respectively, and the hollow cavity 22 of described heat exchanger fin group 2, feed tube 4 is connected with drain pipe 5, described brush sweeper 32 is stainless steel hairbrush.Again as shown in Figure 3, structure of the heat exchanger fin group 2 in the present embodiment and preparation method thereof see number of patent application is: the patent document of EP19860201052, is no longer described in detail at this.
In addition, described feed tube 4 is provided with multiple feed liquor arm 41, and described feed liquor arm 41 is connected with the hollow cavity 22 of described heat exchanger fin group 2 respectively.Described drain pipe 5 is provided with multiple fluid arm (not indicating in accompanying drawing), and described fluid arm is connected with the hollow cavity 22 of described heat exchanger fin group 2 respectively.In the present embodiment, a heat exchanger fin group 2 is connected with a fluid arm with a feed liquor arm 41 respectively, the medium that temperature is lower, in the present embodiment, above-mentioned medium is water, namely the cold water that temperature is lower enters the hollow cavity 22 of each heat exchanger fin group 2 from each feed liquor arm 41 of feed tube 4, flowing out via drain pipe 5, the flue gas of heat flows out from the top of flue gas heat-exchange unit through the below from flue gas heat-exchange unit after the interval 23 adjacent heat exchanger fin group 2 simultaneously, the heat of the flue gas of heat makes the temperature of the water in heat exchanger fin group 2 improve, namely cold water flows out from drain pipe 5 from becoming hot water after feed tube 4 passes through each heat exchanger fin group 2 heat exchange, discharge from the below of flue gas heat-exchange unit after flue gas cool-down after heat exchange simultaneously, thus realize the function reclaiming heat in hot flue gas.
Certainly, according to the needs of actual production, a heat exchanger fin group 2 also can be connected with multiple feed liquor arm 41, multiple fluid arm simultaneously, also can occur that a feed liquor arm 41 is connected with two or more heat exchanger fin groups 2, its operation principle is identical with the present embodiment, is not repeated at this.
In addition, described clearing apparatus also comprises Power Drive Unit, and described Power Drive Unit is connected with described cleaning support 31, and described housing 1 is provided with guide rail 11, and described cleaning support 31 is provided with the pulley 33 matched with described guide rail 11.Again as shown in Figure 1, the top of housing 1 and the both sides of bottom are equipped with guide rail 11, pulley 33 on cleaning support 31 can match with guide rail 11, pulley 33 can slidably reciprocate along guide rail 11, under the driving of Power Drive Unit, cleaning support 31 drives the inside of brush sweeper 32 pairs of flue gas heat-exchange units to clean, namely the inwall of housing 1, the outer surface of each heat exchanger fin group 2 are cleaned, guide rail 11 was both played a supporting role to cleaning support 31 and brush sweeper 32, again the cleaning of brush sweeper 32 was played to the effect of guiding.The arranged direction of certain brush sweeper 32 parallels setting with flow of flue gas direction, when brush sweeper 32 does not work, it is positioned at the end of heat exchanger inside, do not affect flue gas circulation, and when the inwall of brush sweeper 32 pairs of flue gas heat-exchange units and the outer surface of heat exchanger fin group 2 clean, because the arranged direction of brush sweeper 32 parallels with flow of flue gas direction, cleaning is more thorough, cleaning better effects if.
In the application of this flue gas heat-exchange unit, flue gas enters temperature 160 DEG C, cold water temperature 70 DEG C, temperature 115 DEG C after flue gas heat exchange, hot water effluent's temperature 80 DEG C, flue gas flow 20kg/s, heat-recoverable is about 900Kw, the use heat transfer coefficient of the flue gas heat-exchange unit of new clothes is 95W/ (m2 DEG C), use and to find that heat transfer coefficient of heat exchanger declines to a great extent 44.795W/ (m2 DEG C) after a period of time, reclaim heat and also drop to 573Kw, the inside of brush sweeper heat exchanger is now utilized to clean, after removing heat exchanger surface deposit, its heat transfer coefficient reaches 93 W/ (m2 DEG C), heat exchanger recovers normal work, this flue gas heat-exchange unit arranges brush sweeper 32 between adjacent two heat exchanger fin groups 2, by cleaning the attachment cleaning and be attached to heat exchanger plates 21 surface that moves around of hairbrush 32, thoroughly solve the problem causing heat exchange efficiency to reduce because of surface attachments after flue gas heat-exchange unit uses a period of time, eliminate the loaded down with trivial details of artificial unloading's cleaning.
The utility model flue gas heat-exchange unit arranges clearing apparatus in heat exchanger shell, moved around by the brush sweeper between power drive heat exchanger fin group gap, clean the deposit sticked on heat exchanger fin group surface, deposit is discharged from exchanger base, the cleaning of this clearing apparatus is convenient, thoroughly solve the blocking of flue gas heat-exchange unit, adhere to, deposition, the insoluble problems of existing heat exchanger such as heat exchange efficiency is low, and realize automatically controlling cleaning, eliminate the loaded down with trivial details of artificial unloading's cleaning, improve the heat exchange efficiency of heat exchanger, extend the service life of heat exchanger, reduce replacement cost and the use cost of heat exchanger.
Be different from prior art, the utility model flue gas heat-exchange unit thoroughly solve cause heat exchange efficiency to reduce because of surface attachments after flue gas heat-exchange unit uses a period of time problem, eliminate artificial unloading's cleaning loaded down with trivial details, long service life, use cost are low.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
