Specific embodiment
By describing technology contents of the present utility model, structural features in detail, being realized purpose and effect, below in conjunction with enforcement
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Refer to Fig. 1 and Fig. 2, a kind of this utility model paper industry slag storehouse deslagging dust controlling system, including axial flow blower
10th, deslagging chamber 20, boiler 30 and controller 40, described boiler is connected with deslagging chamber, and described deslagging chamber is provided with residual cake valve 21,
Described axial flow blower is arranged at deslagging chamber gateway；Axial flow blower is used for deslagging chamber being aerated take a breath, and axial flow blower is used
In traffic requirement is higher occasion that pressure requirements are relatively low.Slag constantly must be discharged for guarantee boiler continuous safe operation,
In slag-tap furnace, hot solid slag enters in special slag-draining device under stove through burner hearth furnace hopper slag-drip opening, and deslagging chamber is used for depositing stove
Slag, residual cake valve is used for controlling the discharge of slag.The surrounding of described deslagging chamber is removed and is equipped with body of wall 22 at the gateway of deslagging chamber.Row
Grit chamber's surrounding in addition to vehicles while passing mouth, closed, and can reduce the installation power of axial flow blower by other three face walls.
Described boiler includes burner hearth 31 and overfire air fan 32, and described overfire air fan is connected with burner hearth by the first pipeline 33
Connect, described axial flow blower is connected with overfire air fan by second pipe 34；Described controller 40 connects and controls residual cake valve, axle
Flow fan and overfire air fan.Using the negative pressure in boiler secondary blower fan import air channel, using pipeline raising deslagging chamber's slag-drip opening
Dirt enters one's intention as revealed in what one says with overfire air fan and brings in boiler furnace, implementation process, and for strengthening pick-up performance, negative pressure air channel comes in and goes out in deslagging chamber
Mouth installs high flow rate axial flow blower, is conducive to effectively collecting the airborne dust of slag-drip opening, is now switched in fact by controller meanwhile
Interlocked startup axial flow blower during residual cake valve, after closing residual cake valve, stops axial flow blower according to on-site actual situations time delay and runs, will
Remaining dirt is received to the greatest extent.The present embodiment also includes sensor of dust concentration 50, and described sensor of dust concentration is arranged on deslagging interior, dust
Concentration sensor is connected with controller.Sensor of dust concentration is used for carrying out continuous detecting to deslagging interior dust concentration, with
Controller matches it is achieved that the optimum efficiency of dust measuring depositing dust.Further, described controller includes comparator, described comparison
Device is connected with sensor of dust concentration, is higher than the first preset concentration threshold for dust concentration is detected in sensor of dust concentration
During value, generate the enabling signal for starting axial flow blower.So, the work with residual cake valve interlocked startup axial flow blower can be played
With residual cake valve is opened, and deslagging airborne dust concentration uprises, and it is higher than the first preset concentration threshold that sensor of dust concentration detects dust concentration
Value, starts axial flow blower and carries out dust discharge, residual cake valve cuts out, and axial flow blower is also less than first continuing to run until dust concentration
Preset concentration threshold value, just closes axial flow blower.
Further, in the present embodiment, described axial flow blower is arranged on the top at deslagging chamber gateway, axial flow blower edge
Side surrounding is connected with telescopic cover 11, and the matching form of the shape of described telescopic cover and axial flow blower edgewise surrounding closes, described flexible
When cover shrinks, undulate shape folds, and the both sides of telescopic cover are provided with handle 111.When carrying out deslagging and mucking haulage, as long as it is flexible to leave behind
Cover is equal to, by the Distance Shortened of axial flow blower and slag-drip opening, just to siphon away deslagging airborne dust well, permissible by telescopic cover
Change axial flow blower suction direction.Thus solving when actually used, deslagging airborne dust is not easy the problem being sucked away.
In the present embodiment, controller is specially single-chip microcomputer, for receiving and processing the letter that sensor of dust concentration transmits
Breath, is inside provided with corresponding program, is used for starting or stoping axial flow blower, controls residual cake valve, the switch of overfire air fan, with axle stream simultaneously
Blower fan is coordinated.
During use, open residual cake valve, deslagging airborne dust concentration uprises, it is high that sensor of dust concentration detects dust concentration
In the first preset concentration threshold value, start axial flow blower and carry out dust discharge, airborne dust is sent into boiler furnace by overfire air fan, residual cake valve closes
Close, axial flow blower, overfire air fan are also less than the first preset concentration threshold value, ability closing axle stream continuing to run until dust concentration
Blower fan.After implementing the present embodiment, slag storehouse deslagging airborne dust is effectively controlled, and during deslagging, airborne dust is not blown out deslagging chamber；The row of controlling
The impact to peripheral facility, equipment (air compressor machine, controller switching equipment) for the slag airborne dust, improves equipment cycle of operation；Reduce to surrounding enviroment
Pollution.
The foregoing is only embodiment of the present utility model, not thereby limit scope of patent protection of the present utility model,
The equivalent structure transformation that every utilization this utility model description and accompanying drawing content are made, or directly or indirectly it is used in other phases
The technical field closed, is all included in the same manner in scope of patent protection of the present utility model.
