And generalization has positive significant effect, obvious economic effect benefit and beneficial effect are brought.
A kind of carbon powder of generator collection device of the present invention, the spacer mechanism is separately positioned at the top of case inside and bottom
In portion's side wall, and it is equidistantly arranged in a crossed manner.The effective passage distance for extending hot air flow.
Further, the height positioned at the spacer mechanism bottom of case top is less than positioned at the spacer mechanism top of housing bottom
The height in portion, so that collector ring hot blast circulation road forms serpentine passage.Which is able to ensure that hot air flow during flowing
Have with spacer mechanism and sufficiently hit, and hot air flow can be kept out comprehensively to a certain extent, make the effect of energy loss
More, the more conducively collection of carbon dust.
Further, the height positioned at the spacer mechanism bottom of case top is less than the height of air inlet bottom.The design
Mode can ensure that hot air flow enters after housing by spacer mechanism complete barrier, advantageously reduce the kinetic energy of hot air flow, so as to profit
In the collection of carbon dust.
The present invention a kind of carbon powder of generator collection device, the spacer mechanism include be fixed on case inside wall every
Plate, the side of the dividing plate towards air inlet are provided with energy-absorbing plate.Which can ensure that carbon dust hits the effect of energy consumption, be advantageous to
The collecting effect of carbon dust, the problem of solving device maintenance period is short, and utilize energy-absorbing plate lifting energy consumption effect.
Further, the side of the dividing plate towards air outlet is provided with energy-absorbing plate.Hot air flow is running into spacer mechanism stop
In the case of return back out the situation of existing airflow reflux, during backflow, carbon dust can move with hot blast, run into spacer mechanism
When, which can fully increase the consumption of energy, strengthen the collecting effect of carbon dust.
Further, the energy-absorbing plate, which is bolted, is fixed on dividing plate.The connected mode is easy to the dimension of energy-absorbing plate
Shield, be advantageous to the maintenance of device, save maintenance time.
Further, the dividing plate is fixedly connected by welding in enclosure interior, with the sealing effectiveness of reinforced seam.This sets
Meter mode ensures the sealing effectiveness of dividing plate, ensures the blocking effect of hot air flow.
Further, energy-absorbing plate is provided with the inside of the air inlet and lower housing portion where air outlet, the energy-absorbing plate is located at
The lower section of air inlet and air outlet.Ensure that hot air flow can be produced fully in housing in moving conduit using the design of which
Hitting reduces the effect of kinetic energy.
Further, the energy-absorbing plate includes plate body, is provided with the plate body for strengthening energy-absorbing effect, energization damage
The through hole of mistake.Process of the design method based on energy expenditure, by the shock for being designed to be effectively increased carbon dust of through hole, add
The loss of big energy, by energy-absorbing plate in itself and the stop increase carbon dust of dividing plate collection rate, avoid caused by carbon dust other
Problem influences.
A kind of collection method of carbon powder of generator collection device, including step once：
Air inlet and air outlet are set on the top of collection device housing both sides, and intersect in the top and bottom of case inside a,
Welding diaphragm；
B, during welding diaphragm, make the height of dividing plate bottom of case top less than the height at the top of housing bottom dividing plate, by every
Plate forms serpentine hot blast circulation road with housing cavity；
C, below the both sides of dividing plate, the air inlet where housing inner side and air outlet below where the inner side of housing set and open
Energy-absorbing plate provided with through hole；
D, dust-collecting box is set in housing bottom, dust-collecting box extends to dividing plate and housing, makes the carbon of the kinetic energy deficiency in flow process
Powder dust, impact energy absorption plate and by energy-absorbing plate through hole hit dividing plate energy loss after carbon dust dust under gravity from
Fallen under so in dust-collecting box；
E, hot air flow is introduced from air inlet, carried out in its natural state in housing, and discharged from air outlet, complete the receipts of carbon dust
Collection.
Further, in the step a, positioned at case top dividing plate quantity than the dividing plate positioned at housing bottom number
Amount is more 1, so that the dividing plate close to air inlet and air outlet is located at case top.The hot air flow which can ensure to enter fills
Divide and be blocked, so as to flow to lower section, play effective cushioning effect, in addition, using the design energy in the position close to air outlet

Kinetic energy, in actual applications, kinetic energy declines after air-flow velocity declines, and the impurity especially weight mixed in gas lays particular stress on a bit
Dust can fall naturally under gravity.And in the design, spacer mechanism mainly realizes two purposes, first, using dividing plate
The setting of mechanism extends the flow path of hot air flow, loses the Energy Efficient of hot air flow；Second, using spacer mechanism to hot blast
Stream is stopped, and is hit for dust in hot air flow, and during shock, energy loss is obvious.Two kinds of purposes
The separation between gas and dust is enough realized in design based on gas kinetic energy low energy.And the carbon dust collecting in current steam turbine generator fills
In putting, the means of generally use add the design of filter for air draft mechanism, and not only increase the negative of filter screen using traditional technology
Carry, while shorten maintenance period, meanwhile, equipment volume is big, also there is bigger requirement to erection space.Traditional collection device is
Increase the kinetic energy of hot air flow, to realize the filtering of the discharge of gas and carbon dust, and the design is to use natural gravity, needn't be extraneous
Power, and during actually collecting, increase the energy loss of thermal current as far as possible, it is simple in construction so as to realize, save
