According to the technical scheme, the boiler shell membrane type water wall structure comprises a boiler shell, an internal furnace and a plurality of smoke tubes, wherein the internal furnace is located in the boiler shell, a membrane type water wall is arranged at one end of the boiler shell, a smoke inlet of the membrane water wall is communicated with an outlet of the internal furnace, a smoke outlet of the membrane type water wall is communicated with inlets of the smoke tubes, and then a closed structure is formed.
Description
Technical field
The utility model relates to a kind of boiler, particularly a kind of shell film water cold wall structure.
Background technology
Along with the continuous high speed development of national economy, " greatly " type enterprise, hotel, hotel, school etc. continue to bring out, increasing to the demand of large-scale smaller hard flour pancake boiler.Along with the increase of boiler capacity, the thermic load of high-temperature region---little smoke-box is corresponding increase also, and due to little smoke-box front tube sheet place a large amount of smoke pipe that gathered, the spacing of smoke pipe is less, easily causes current not smooth, localized hyperthermia, thus produce a series of safety problems.
Current little smoke-box front tube sheet and the problem that is connected smoke pipe and mainly exists following several respects:
1, the easy fouling of tube sheet water side, causes heat transfer bad, causes that exhaust gas temperature rises, and boiler efficiency declines.
2, tube sheet water side and smoke pipe pipe end conduct heat byer force, and water circulation is violent, easily forms partial vaporization, causes this place cooling bad, and wall temperature raises, overheated and crack etc., make damage in boilers.
Above problem the lighter increases user's operating cost, or causes user normally not use, and affects user's normal operation; Severe one might produce security incident, causes heavy economic losses!
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of shell film water cold wall structure simple in structure, with low cost for the problem of above-mentioned existence, can effectively reduce flue-gas temperature, guarantee the safety of boiler.
The technical scheme that the utility model adopts is: shell film water cold wall structure, comprise shell, be positioned at flue and the some smoke pipes of this shell, described shell one end is provided with fin panel casing, the mouth that enters of this fin panel casing is communicated with the outlet of flue, and outlet flue is communicated with formation closed structure with the entrance of smoke pipe.
Described fin panel casing comprise an end opening tubular side membrane wall, be arranged in side membrane wall and be divided into vertically the middle membrane wall of two cavitys; Wherein the openend of side membrane wall and shell are tightly connected, middle membrane wall one end and shell are tightly connected, between the other end and side membrane wall blind end, leave space, two cavitys are communicated with and form U-shaped flue, this U-shaped flue one end is communicated with the outlet of flue as entering mouth, and the other end is communicated with the entrance of smoke pipe as outlet flue.
The beneficial effects of the utility model are: 1, the utility model is provided with fin panel casing in shell one end, the mouth that enters of this fin panel casing is communicated with the outlet of flue, outlet flue is communicated with formation closed structure with the entrance of smoke pipe, utilize fin panel casing to increase heating surface and caloric receptivity, can effectively reduce the flue-gas temperature that enters smoke pipe, thereby reduce the wall temperature of flue end and tube sheet, improved the water circulation at this place, thereby guaranteed the safety of smoke pipe and tube sheet.2, flue gas is after the heat absorption of fin panel casing and smoke pipe is cooling, the temperature of its discharge has approached conventional smaller hard flour pancake boiler three return smoke temperature, therefore can omit three backhaul smoke pipes, therefore the utility model compared with prior art, saved the little smoke-box of boiler and three backhaul smoke pipes, structure is more simple, cost is cheaper.3, because fin panel casing regional space is large, therefore superheater can also be set, provide superheated steam to user.

Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
Detailed description of the invention
As shown in Figure 1, the present embodiment comprises shell 2, is positioned at flue 3 and the some smoke pipes 4 of this shell, and described shell 2 one end are provided with fin panel casing 1, the mouth that enters of this fin panel casing is communicated with the outlet of flue 3, and outlet flue is communicated with formation closed structure with the entrance of smoke pipe 4.
As shown in Figure 2 and Figure 3, described fin panel casing 1 comprise an end opening tubular side membrane wall 1-1, be arranged in side membrane wall 1-1 and be divided into vertically the middle membrane wall 1-2 of two cavitys; Wherein the openend of side membrane wall 1-1 and shell 2 are tightly connected, middle membrane wall 1-2 one end and shell 2 are tightly connected, between the other end and side membrane wall 1-1 blind end (one end relative with openend), leave space 1-3, two cavitys are communicated with and form U-shaped flue, this U-shaped flue one end is communicated with the outlet of flue 3 as entering mouth, and the other end is communicated with the entrance of smoke pipe 4 as outlet flue.
Fuel forms high-temperature flue gas (flue-gas temperature in flue exit is 1100 DEG C of left and right) afterwards in the interior abundant burning of flue 3, a cavity interior (directly exporting with flue the cavity being communicated with) that enters fin panel casing 1, mainly absorbs heat and passes to the water in water-cooling wall pipe in radiant heat transfer mode; Flue gas through in membrane wall 1-2 carry out the large turning of 180 degree by space 1-3 after blocking and enter in another cavity, again absorb heat in radiant heat transfer mode and pass to the water in water-cooling wall pipe, flue gas is further cooling, cigarette temperature drops to 750 DEG C of left and right; Then enter smoke pipe 4, by the further heat exchange of convection heat transfer' heat-transfer by convection mode, flue-gas temperature finally reaches about 250 DEG C discharges.Conventional smaller hard flour pancake boiler in the cigarette temperature at smoke pipe entrance and tube sheet place 1100 DEG C of left and right, the cigarette temperature at this place of the present embodiment is 750 DEG C of left and right, has declined nearly 350 DEG C compared with routine techniques, therefore greatly reduces the wall temperature at this place, thereby improve water circulation, guaranteed the safe operation of boiler.
