Abstract
The utility model relates to a water trap for a biogas generating pit boiler high-temperature fume heat exchanger, which comprises a heat exchanger part and a water removal part. The heat exchange part is a fume heat exchanger(20) slantingly arranged on the inner wall of the biogas generating pit with an inclination angle of 10-15 degrees with the horizontal line, and the lowest point of the heat exchange part is located at an outlet(5) of the fume heat exchanger. The inlet of the fume heat exchanger is communicated with the fume exhaust pipeline of a boiler(19) through a fume exhaust pipeline(16), and a blower(17)is arranged on the fume exhaust pipeline(16). The water removal part is a water removal tank(6)communicated with a chimney(12), and the outlet(5)of the fume heat exchanger is communicated with the water removal tank(6). The water trap is capable of removing the water accumulated in the heat exchanger.
Description
Technical field
The utility model relates to a kind of de-watering apparatus of high-temperature flue gas heat exchanger, particularly a kind of de-watering apparatus of used for methane tank boiler high temperature flue gas heat exchange device.
Background technology
At the boiler afterheat heating biogas pool device of present design, because this methane-generating pit is to adopt the inner heating of high-temperature flue gas, along with the carrying out of heat transfer process, flue-gas temperature reduces, the northeast winter temperature is very low, and attemperator is just arranged at last, and the flue-gas temperature behind the process heat exchanger is about 20 degree, be lower than the condensation point of steam in the flue gas, have steam and condense in heat exchanger inside, condense for a long time, making has ponding in the flue gas heat exchange tube, so that stop up exhaust gases passes, cause flue gas heat exchange to be forced to stop.For heat exchange is carried out smoothly, this heat-exchanger rig needs to remove the inner ponding of heat exchanger, and will conveniently remove inner carbon distribution, does not also have relevant technology to solve this problem at present.
Summary of the invention
At the deficiency that high-temperature flue gas heating biogas pool technology exists, the purpose of this invention is to provide a kind of de-watering apparatus of high-temperature flue gas heat exchanger, this de-watering apparatus can be removed the inner ponding of heat exchanger.
Above-mentioned purpose of the present utility model is achieved in that accompanying drawings is as follows:
A kind of de-watering apparatus of used for methane tank boiler high temperature flue gas heat exchange device, comprise heat exchanging part and remove water section, wherein heat exchanging part is for placing the methane-generating pit inwall and horizontal by the tilted-putted flue gas heat exchange device 20 of 10-15 degree, its minimum point is at outlet 5 places of flue gas heat exchange device, the import of flue gas heat exchange device communicates with boiler 19 smoke discharging pipes by smoke discharging pipe 16, and smoke discharging pipe 16 is provided with blower fan 17.Remove water section and remove pond 6 for what be connected with chimney 12, the outlet 5 of flue gas heat exchange device be communicated with except that pond 6.
Described flue gas heat exchange device 20 is made of the circular passage up and down 2,3 that is connected with Vertical Channel 4.
Described pond 6 usefulness the collecting-tank dividing plates 8 that remove be left and right sides two parts, and left and right sides two parts are communicated with by the gap that the dividing plate bottom stays, chimney 12 be connected except that the pond left-half, be connected except that well 13 and except that the pond right half part.
Said removing in the well 13 has except that water level in water pool scale 11, indicates down scale 9 and high scale 10 above.
The beneficial effects of the utility model are as follows:
Annular up and down flue all become with horizontal plane 10-15 degree angle be for help steam in the flue gas solidify aqueous water that the back forms can be successfully along flue stream to exhanst gas outlet, remove the pond thereby arrive, making does not have ponding in the flue gas heat exchange tube, and the heat exchange of flue gas is guaranteed to carry out smoothly.
Description of drawings
The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment:
Fig. 1 is the structure chart of the de-watering apparatus of used for methane tank boiler high temperature flue gas heat exchange device.
Among the figure: 1-charging aperture 2-goes up under the annular flue 3-the vertical flue 5-of annular flue 4-flue outlet 6-and removes pond 7-and remove pond water surface 8-and remove pond dividing plate 9-and remove under the scale of pond scale 10-and remove pond scale high scale 11-and remove water level in water pool scale 12-chimney 13-and remove well 14-methane-generating pit 15-pipe and connect 16-smoke discharging pipe 17-blower fan 18-valve 19-hot-water boiler 20-flue gas heat exchange device
The specific embodiment
1 is the charging aperture of methane-generating pit 12, valve 18 and blower fan 17 are installed on the smoke discharging pipe 16 of hot-water boiler 19, and be connected with last annular flue 2, vertically flue 4 by pipe connect 15 up and down annular flue 2,3 link together, this three constitutes the flue gas heat exchange device, and following annular flue 3 is connected with flue outlet 5, flue outlet 5 with remove pond 6 and be connected, go up annular flue 2 and following annular flue 3 horizontal by 10～15 degree, minimum point is at flue outlet 5 places.High-temperature flue gas enters annular flue 2 by smoke discharging pipe 16, then by uniform vertical flue 4, again through circulating line 3 back flow direction outlets 5 down, in this heat transfer process, flue-gas temperature descends very fast, to reach during outlet about 25 degree, thereby the water generation of condensing will be arranged in this process, because annular flue 2 up and down, 3 all horizontal by 10～15 angles, and minimum point is at outlet 5 places, help steam in the flue gas solidify aqueous water that the back forms can be successfully along flue stream to exhanst gas outlet water, remove pond dividing plate 8 and will be divided into left and right sides two parts except that the pond, left and right sides two parts are communicated with by the gap that dividing plate stays, chimney 12 with remove the pond left-half and be connected, remove well 13 and be connected except that the pond right half part, removing water level in water pool scale 11 is arranged in except that well 13, remove water level in water pool scale 11 and indicate high scale 10 and following scale 9, the gap that following scale 9 stays for dividing plate, high scale 10 removes water level in water pool and observes by scale for removing the height of bottom, pond to outlet 5, remove the minimum scale 9 that remains on down of water level in the pond, flue gas is discharged from chimney 12 smoothly like this, and the water that removes in the pond can not surpass high scale 10, otherwise flue gas can't normally be discharged.Observe except that the water level in the pond by removing water level in water pool scale 11, the control water level carries out flue gas heat exchange smoothly.
