Description
Technical field
The utility model relates to a kind of electric cleaner, relates in particular to a kind of integrated flue gas waste heat recovery low temp. electric deduster.
Background technology
At present, most flue gas waste heat recovery apparatus is arranged on coal-burning boiler rear portion as equipment independently, or is arranged between electric cleaner inlet flue duct and import end socket, or is arranged on electric cleaner exhaust pass rear portion.
Flue gas waste heat recovery apparatus is arranged on the exhaust gases passes after coal-burning boiler needs newly to account for larger place, simultaneously because the flue gas flow rate variation of flue and flue gas waste heat recovery apparatus can cause the pressure loss greatly, increases the energy consumption of blower fan; Be arranged on outside other position of electric cleaner, can not be by both comprehensive Design centralized Control, thus can not reach the energy-conservation optimum efficiency with putting forward effect; If flue gas waste heat recovery apparatus is arranged in to electric cleaner exhaust pass, just can not play the effect that improves electric cleaner dust-collecting efficiency completely.
Utility model content
The utility model provides a kind of integrated flue gas waste heat recovery low temp. electric deduster, is intended to solve the flue gas waste heat recovery apparatus on low temp. electric deduster in prior art and captures the problem that space is large, the pressure loss is large.
In order to solve above technical problem, the utility model is achieved through the following technical solutions: a kind of integrated flue gas waste heat recovery low temp. electric deduster, comprise import end socket that inside is provided with the basic machine of dust pelletizing system, is connected with basic machine left end, with the inlet flue duct that import end socket left end is connected, also comprise the flue gas waste heat recovery apparatus being arranged in import end socket.
Further, described flue gas waste heat recovery apparatus is the finned tube group being comprised of some sections of end to end finned tubes, in described finned tube group, is provided with mobile medium, and described finned tube group is connected with control system; By mobile medium, take away the part heat of flue gas.
Further, described basic machine is provided with the thermocouple for testing electric cleaner internal temperature, and described thermocouple is connected with control system; Thermocouple feeds back to control system by the electric cleaner internal temperature of test, then regulates the flow velocity of flow media, and then the temperature that regulates flue gas to enter electric cleaner basic machine, has improved electric cleaner dust-collecting efficiency.
Further, the tapered helical structure of described finned tube group, the little one end of described cone-type spiral structural openings is near inlet flue duct, and described finned tube group is coaxial with inlet flue duct; Be convenient to increase the uniformity of air-flow.
Compared with prior art the utility model has the advantages that: flue gas waste heat recovery apparatus of the present utility model is arranged on import end socket inside, thereby effectively saved installing space, reduced the pressure loss, the waste heat of the utility model in can recovered flue gas, play the effect of energy-conserving and environment-protective, the flue gas dust collection better effects if after electric cleaner reduces for temperature.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Consult Fig. 1, a kind of integrated flue gas waste heat recovery low temp. electric deduster, comprise import end socket 2 that inside is provided with the basic machine 1 of dust pelletizing system, is connected with basic machine 1 left end, with the inlet flue duct 4 that import end socket 2 left ends are connected, it is characterized in that: also comprise the flue gas waste heat recovery apparatus being arranged in import end socket 2; Described flue gas waste heat recovery apparatus is the finned tube group 3 being comprised of some sections of end to end finned tubes, in described finned tube group 3, is provided with mobile medium, and described finned tube group 3 is connected with control system; Described basic machine 1 is provided with the thermocouple 5 for testing electric cleaner internal temperature, and described thermocouple 5 is connected with control system; The tapered helical structure of described finned tube group 3, the little one end of described cone-type spiral structural openings is near inlet flue duct 4, and described finned tube group 3 is coaxial with inlet flue duct 4.
During use, the waste gas of emitting from coal fuel heating fire grate enters electric cleaner from inlet flue duct 4, while flowing through flue gas waste heat recovery apparatus, under the effect of flow media, the temperature of flue gas is lowered, flue gas evenly enters basic machine 1 under the finned tube effect of cone-type spiral shape, thermocouple 5 record by cooling after flue-gas temperature, then by the temperature feedback recording to control system, during excess Temperature, increase the flow velocity of flow media; When temperature is too low, reduce the flow velocity of flow media, ensure a temperature that dust-collecting efficiency is high, in basic machine 1, under the effect of dust pelletizing system, the particle flue dust in flue gas is removed, removed particle flue dust is got rid of by defeated ash silo 7, and the flue gas being cleaned is got rid of by exhaust pass 6.
Flue gas waste heat recovery apparatus of the present utility model is arranged on import end socket inside, thereby effectively saved installing space, reduced the pressure loss, the waste heat of the utility model in can recovered flue gas, play the effect of energy-conserving and environment-protective, flue gas dust collection better effects if after electric cleaner reduces for temperature, the utility model feeds back to control system by thermocouple by the flue-gas temperature in basic machine, control the flow velocity of flow media, thereby guarantee that electric cleaner internal temperature is more stable, dust-collecting efficiency is higher, the helical structure that heat exchanger tube is tapered, can increase the uniformity of air-flow.
The foregoing is only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
