Abstract
The invention relates to a mechanical dust cleaner with pipe heat exchanger, which can be used in the pipe heat exchanger of generator smoke desulfuration. It comprises the power device and the dust cleaner moving along the axle of wing pipe. Wherein, the power of power device via the chain can be transmitted to the dust cleaner; its main power part can make the dust cleaner move along the axle of wing pipe; the driven power part via a group of gear transmission device inside the frame of dust cleaner and the brush drive chain wheel can drive the brush in oscillating motion between pipe rows. The invention uses the axial motion along the wing pipe of dust cleaner and the oscillating motion of rotational brush between the pipe rows to realize the full-direction dust cleaning on the surface of wing pipe. The rotational brush has direct contact with the heat exchange surface, to use the kinetic energy of rotational brush to clean the dust from the surface, which has better effect to clean dry and wet dust.
Description
Technical field
The present invention relates to a kind of deashing device that is used for means of flue gas desulfurization of power plant or similar field pipe heat exchanger (comprising hydrophily formula heat exchanger, heat exchange of heat pipe etc.), more general deashing device has stronger deashing ability and lower energy consumption.
Background technology
In present known this field, deashing device roughly comprises: acoustic wave ash ejector, gas-burning pulse ash-blowing device, steam sootblower, air duster, water jet soot blower, shot cleaner or the like.The technical difficulty of preceding two kinds of soot blowers is big, and it is different and different with the dust stratification type because of type to blow grey conceptual design, is difficult for grasping, and is difficult to accomplish not stay the dead angle; Limited for the wet grey effect below the dew-point temperature in the removal flue gas desulfurization simultaneously.The difficult arrangement of steam sootblower, air duster, water jet soot blower, the dead angle is many, installs huge; Ash becomes sticking damp simultaneously, and easily deposition, difficulty are blown, and the acid corrosion of tube wall increases the weight of.The steel ball rate of recovery of shot cleaner is low, and the deashing dead angle is many and big.If run into sticking ash, steel ball is just clung with dust stratification by ash easily halfway and stops up flue jointly, the dedusting effect extreme difference.In addition, all there is the high shortcoming of energy consumption in above-mentioned deashing device.
Summary of the invention
Technical problem: in order to overcome the problem that existing deashing device exists, the invention provides a kind of mechanical ash cleaner of pipe heat exchanger, this device contacts with the direct of heat exchange surface by rotational head, dust stratification is cleared away from the surface, and energy consumption is very low.
Technical scheme: the present invention realizes by following measure: the mechanical ash cleaner that is used for pipe heat exchanger is by the power set on the housing that is located at heat exchanger and be located on the sliding frame and can constitute along ash handling equipment two parts of finned tube axially-movable; Power set comprise drive motor, sprocket for main drive and main transmission chain; Ash handling equipment comprises driven sprocket, brush, gear drive, brush drive sprocket and brush chain drive-belt, sliding frame; Wherein, the motor of power setting part joins by deceleration and sprocket for main drive, and sprocket for main drive is linked by the driven sprocket of main transmission chain and ash handling equipment part; Gear drive and the driven sprocket input power that joins, the output of gear drive connects the brush drive sprocket, by brush chain drive-belt link brush drive sprocket and brush; Guide rail is parallel with finned tube, and sliding frame is enclosed within on the guide rail and can slides up and down.Brush has many groups.
The power of power set is passed to ash handling equipment by chain via the driven sprocket on the framework, its active force partly makes ash handling equipment then drive brush by one group of gear drive in the framework and corresponding driving chain from power section and to do the rotation reciprocating motion between pipe row along the axially-movable of finned tube.Reciprocating motion between pipe row just can realize the surperficial omnibearing deashings of all finned tubes along the axially-movable of finned tube and rotational head by ash handling equipment.
Beneficial effect: the rotational head of mechanical ash cleaner directly contacts with heat exchange surface, utilizes the kinetic energy of rotational head that dust stratification is cleared away from the surface, for dry state, hygrometric state dust stratification good effect is arranged all.Select suitable moving step length then to be easy to realize the thorough deashing of heat exchanger, do not stay the dead angle.Drive motor only need overcome the frictional resistance of deashing device, so power of motor is little, and energy consumption is very low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.Fig. 3 is the plan structure schematic diagram of Fig. 1.
Have among the figure: the housing 10 of motor 1, sprocket for main drive 2, main transmission chain 21, guide rail 3, finned tube 4, driven sprocket 5, brush 6, gear drive 7, brush drive sprocket 8, brush chain drive-belt 81, sliding frame 9, heat exchanger.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
As Fig. 1, device of the present invention by this device by power set on the housing 10 that is located at heat exchanger and be located on the sliding frame 9 and can constitute along ash handling equipment two parts of finned tube 4 axially-movables; Power set comprise drive motor 1, sprocket for main drive 2 and main transmission chain 21; Ash handling equipment comprises driven sprocket 5, brush 6, gear drive 7, brush drive sprocket 8 and brush chain drive-belt 81, sliding frame 9; Wherein, the motor 1 of power setting part joins by deceleration and sprocket for main drive 2, and sprocket for main drive 2 is linked by the driven sprocket 5 of main transmission chain 21 with the ash handling equipment part; Gear drive 7 and the driven sprocket 5 input power that joins, the output of gear drive 7 connects brush drive sprocket 8, by brush chain drive-belt 81 link brush drive sprockets 8 and brushes 6; Guide rail 3 is parallel with finned tube 4, and sliding frame 9 is enclosed within on the guide rail 3 and can slides up and down.Brush 6 has many groups.
Four jiaos of sliding frame 9 are contained on four guide rails 3, and 3 on guide rail is fixed on the housing 10 of heat exchanger, and sliding frame 9 can move up and down by relative four guide rails 3.Power set adopt the chain kind of drive: the two ends of sliding frame 9 link with chain by driven sprocket 5, and chain then hangs on the last lower sprocket of sprocket for main drive 2, and drives by motor 1.
When motor 1 work, lower sprocket drive ash handling equipment slowly moves to certain direction in the driving.Power is passed to ash handling equipment by chain via the driven sprocket on the sliding frame 95, except ash handling equipment can then be driven brush by one group in the framework custom-designed gear drive 7 and brush drive sprocket 8 from power section and do rotation between pipe row, move back and forth along the axially-movable of finned tube.Rotational head 6 directly contacts with the finned tube heat exchange surface, utilizes the kinetic energy of rotational head 6 that dust stratification is cleared away from the surface.Reciprocating motion between pipe row just can realize the surperficial omnibearing deashings of all finned tubes along the axially-movable of finned tube and rotational head 6 by ash handling equipment.
When ash handling equipment is reached home, motor 1 counter-rotating, ash handling equipment returns in opposite direction, proceeds cleaning.
