Abstract
The utility model provides a deashing device applied in flue gas waste heat recovery pipe heat exchangers with strong coherence in metallurgy industry or pipe heat exchangers in similar fields. The device consists of a power device and ash handling equipment that can axially move along a heat exchange tube, wherein the power of the power device is transferred to the ash handling equipment through a chain, a main power part thereof causes the ash handling equipment to be capable of axially moving along the heat exchange tube, and an auxiliary power part thereof drives a brush head to do rotary reciprocating motion between tube banks through a group of gear transmission mechanisms and a brush head drive sprocket in a frame of the ash handling equipment; and due to the axial movement of the ash handling equipment along the heat exchange tube and the reciprocating motion of the rotary brush head between the tube banks, the omnibearing ash removal of all the heat exchange tubes can be realized. The rotary brush head of a mechanical ash handling equipment directly contacts a heat exchange surface, and the kinetic energy of the rotary brush head is utilized to sweep dust deposition off the surface, with favorable effect on both dry and wet dust deposition.
Description
Technical field
The utility model relates to a kind of deashing device that is used for means of flue gas desulfurization of power plant or similar field heat exchanger (comprising hydrophily formula heat exchanger, heat exchange of heat pipe), and 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 corrosion-resistant of wall pipe 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.
The utility model content
Technical problem: in order to overcome the problem that existing deashing device exists, the utility model provides a kind of deashing device of heat exchanger, and 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 utility model is realized by following measure: the mechanical ash cleaner that is used for 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 heat exchanger 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 heat exchanger 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 heat exchanger tube.Reciprocating motion between pipe row just can realize the surperficial omnibearing deashings of all heat exchanger tubes along the axially-movable of heat exchanger 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 realize the thorough deashing of heat exchanger easily, 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 utility model.
Fig. 2 is Fig. 1 left side TV structure schematic diagram.
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 utility model is elaborated.
As Fig. 1, device of the present utility model is located at the power set on the housing 10 of heat exchanger and is located on the sliding frame 9 and can constitutes along ash handling equipment two parts of finned tube 4 axially-movables by this device; 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 ash handling equipment; 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 heat exchanger tubes along the axially-movable of heat exchanger tube and rotational head 6 by ash handling equipment.
When ash handling equipment reaches terminal point, motor 1 counter-rotating, ash handling equipment returns in opposite direction, proceeds cleaning.
