Description
Technical field
The present invention relates to a kind of boiler, more particularly to a kind of reclaiming type coal-burning boiler.
Background technology
The energy waste phenomenon of the coal-burning boiler of prior art, particularly Industrial Boiler is extremely serious.The energy knot of China
Based on coal, the industry coal-boiler having a large capacity and a wide range will consume substantial amounts of coal to structure, and the most structure list of existing coal-burning boiler
One, tail gas enters from top to bottom purifier by pipeline, and the setting of such pipeline easily causes coal dust deposit buildup in tail gas
In the interface of connection purifier, the obstruction of pipeline is easily caused, tail gas circulation is obstructed, and flue blocks and boiler can be transported
Row produces great inhibition, causes serious economic loss.
The content of the invention
It is an object of the invention to provide a kind of reclaiming type coal-burning boiler of energy-conserving and environment-protective.
To reach above-mentioned purpose, the technical scheme is that：A kind of reclaiming type coal-burning boiler, including boiler body, also
Including bracing frame, the flue dust sedimentation pipe in spatially spiral shape, check valve and coal dust accumulator tank, the side that support frame as described above passes through bridge joint
Formula makes the flue dust sedimentation pipe in spatially spiral shape be wrapped in outside boiler body, the flue dust sedimentation pipe upper end in spatially spiral shape
Communicate with boiler body upper end, the flue dust sedimentation pipe lower end in spatially spiral shape is provided with the arm of two Y-shaped distributions, one
Individual is the residue outlet communicated with coal dust accumulator tank, and another is the pipe for being connected to purifier；The check valve is located at and is in
The flue dust sedimentation pipe of spatially spiral shape and the junction of boiler body.
The invention has the beneficial effects as follows：The flue dust sedimentation pipe in spatially spiral shape is wound with outside boiler body, bracing frame is used
To fix chimney, the flue dust sedimentation pipe in spatially spiral shape and boiler body are communicated, the flue dust sedimentation pipe in spatially spiral shape
Two arms of the Y-shaped distribution in lower end, two arms are respectively the residue outlet that communicates with coal dust accumulator tank and are connected to purifier
Pipe, it is such be provided with beneficial to boiler exhaust gas by spatially spiral shape flue dust sedimentation pipe when precipitate coal dust,
Coal dust is collected by residue outlet to coal dust accumulator tank, and coal dust is recycled afterwards, and the tail gas after precipitation is from pipe
Purifier is entered into, so fuel is also saved while environmental protection is carried out, the effect of recyclable fuel is realized, is in
The check valve that the flue dust sedimentation pipe upper end of spatially spiral shape is arranged where being connected with boiler body is conducive to entering tail gas
Will not be back in boiler body after flue dust sedimentation pipe in spatially spiral shape.Pass through can tail gas by the setting of this structure
Flue dust sedimentation pipe into spatially spiral shape is settled, and coal dust enters subsider by residue outlet, and tail gas is entered by pipe
Purifier, does not result in the obstruction to pipeline, and tail gas stream can be kept unobstructed logical, and can recycle fuel.
Further, by many curved pipes, from top to bottom helical arrangement is constituted the flue dust sedimentation pipe in spatially spiral shape,
Two neighboring curved pipe is connected by ring flange, and the pipe and residue outlet are located at the flue dust in spatially spiral shape of least significant end
On sedimentation pipe.
Connected by ring flange, contribute to dismantle convenient when cleaning maintenance is needed.
Further, the coal dust accumulator tank is provided with filler away from one end of residue outlet.
Filler is provided with one end away from residue outlet of coal dust accumulator tank, the setting of filler can be by adding water to heavy
The coal dust for forming sediment plays humidification when discharging residue outlet so that coal dust will not be blown away by boiler exhaust gas.
Further, support frame as described above one end is bridged on ring flange, and the support frame as described above other end is supportted on ground.
Bracing frame one end is supported on ground one end other end and carries out to the flue dust sedimentation pipe junction method in spatially spiral shape
The support of blue disk, can so realize the more firm fixation entirely flue dust sedimentation pipe in spatially spiral shape.
Further, the residue outlet and horizontal plane angle are 46 degree to 90 degree.
Residue outlet and horizontal plane angle 46 to 90 are spent, and more than the angle of angle of repose, coal dust can be made to enter into coal faster
In powder accumulator tank, more stops will not be done in the flue dust sedimentation pipe in spatially spiral shape, it is to avoid coal dust excessively make by accumulation
Into obstruction.
Description of the drawings
Fig. 1 is a kind of structural representation of reclaiming type coal-burning boiler embodiment of the invention；
Fig. 2 is a kind of sectional view of reclaiming type coal-burning boiler boiler body of the invention.
Specific embodiment
Reference：Boiler body 1, pipe 2, the flue dust sedimentation pipe 3 in spatially spiral shape, ring flange 4, coal dust is reclaimed
Groove 5, check valve 6, filler 7, residue outlet 8, bracing frame 9, interior stove 10, push pedal 11, furnace chamber 12, hydraulic cylinder 13.
Embodiment：A kind of reclaiming type coal-burning boiler, including boiler body 1 as shown in Figure 1 is also including bracing frame 9, in space
Spiral flue dust sedimentation pipe 3, check valve 6 and coal dust accumulator tank 5, bracing frame 9 is made in spatially spiral shape by way of bridge joint
Flue dust sedimentation pipe 3 be wrapped in outside boiler body 1, the upper end of flue dust sedimentation pipe 3 in spatially spiral shape and the upper end phase of boiler body 1
Logical, the lower end of flue dust sedimentation pipe 3 in spatially spiral shape is provided with the arm of two Y-shaped distributions, and one is and the phase of coal dust accumulator tank 5
Logical residue outlet 8, another is the pipe 2 for being connected to purifier；Check valve 6 is located at the sedimentation of the flue dust in spatially spiral shape
The junction of pipe 3 and boiler body 1, the flue dust sedimentation pipe 3 in spatially spiral shape is by many curved pipes helical arrangement from top to bottom
Composition, two neighboring curved pipe connected by ring flange 4, pipe 2 and residue outlet 8 be located at least significant end in spatially spiral shape
On flue dust sedimentation pipe 3, coal dust accumulator tank 5 is provided with filler 7 away from one end of residue outlet 8, and the one end of bracing frame 9 is bridged on ring flange
On 4, the other end of bracing frame 9 is supported on the ground, and residue outlet 8 and horizontal plane angle are 46 degree to 90 degree.
As shown in Fig. 2 also including interior stove 10 in boiler body 1, hydraulic cylinder is installed between boiler body 1 and interior stove 10
13, the one end of hydraulic cylinder 13 connects push pedal 11 in interior stove 10 by interior stove 10, and hydraulic cylinder 13 is connected to controlling organization.
Using method：
When boiler comes into operation, in placing fuel into furnace chamber 12, fuel is lighted, is when needing to adjust boiler temperature, it is only necessary to
Hydraulic cylinder 13 is controlled by controlling organization and promotes push pedal 11, when higher temperature is needed, push pedal 11 is pulled to into the wall direction of interior stove 10,
Control coal and the contact area of air, make more coals and air contact, raise the more vigorous boiler temperature of fuel combustion.When
When needing lower temperature, control push pedal 11 makes coal diminish with the contact area of air, and now, more dumps are stacked, few
Part coal and air contact, reduce fuel economy, and boiler temperature is reduced.And can be with during push pedal 11 is slippaged
The cinder of furnace wall is cleared up.
Because tail gas is ascending motion, bracing frame 9 by way of bridge joint twines the flue dust sedimentation pipe 3 in spatially spiral shape
It is wound on outside boiler body 1, the upper end of flue dust sedimentation pipe 3 in spatially spiral shape and the upper end of boiler body 1 communicate, tail gas is entered in sky
