Description
Technical field
This utility model is related to a kind of cork dry quenching disposable dust remover dust removing system crawl reversion electrical control.
Background technology
Dry coke quenching is to cool down the incandescent coke that coke oven is produced using inertia recyclegas, reclaims heat and produces into steam generator system
Raw steam, steam can be used to drive steam turbine generator generating or supply other workshops use.
Coke is the irregular porous body containing different thicknesses crackle and defect with carbon as main component.In dry coke quenching life
During product, oven-fresh incandescent coke Jing mechanical handings and certain altitude difference are fallen in coke dry quenching furnace, are fallen in coke dry quenching furnace
There is heat convection in the cold cycle gas that incandescent coke and coke dry quenching furnace bottom enter, period coke is through phase mutual friction and repeatedly
Collision, makes the crackle in coke ftracture in advance, while also generating a large amount of coke powders, these coke powders are by the height after heat exchange
Warm recyclegas is carried secretly from ring-shaped flue and gone out, if not removing, coke powder can gradually wear out follow-up equipment and pipeline, and then affect
The normal production of dry coke quenching, therefore, the coke powder centralized collection produced during dry coke quenching is produced.
There is third dedusting system in dry coke quenching technique at present, i.e., usually said one-time dedusting, final dusting and environment are removed
Dirt.One-time dedusting is using gravity sedimentation type dedusting, mainly for trapping bulky grain coke powder and preventing the boiler superheater that weares and teares.Weight
Power decanter type dedusting is a kind of simple, inefficient dedusting method, and the dust granules that gravity sedimentation type falls are larger, enter and once remove
Form ash-valve putty phenomenon is easily caused in dirt dust removing system.And after the operating of form ash-valve it is one direction rotation, after putty only
Energy unpacked type ash-valve, form ash-valve is installed between water cooling sleeve pipe and storage hopper, and dismounting difficulty is big, recover installation is stranded
It is difficult.
Utility model content
The purpose of this utility model is to provide that one kind can greatly reduce dust removing system downtime and maintained equipment is convenient
Cork dry quenching disposable dust remover dust removing system crawl inverts electrical control.
The purpose of this utility model is achieved in that a kind of cork dry quenching disposable dust remover dust removing system crawl reversion is electric
Control, at least includes：Ash discarding bucket, connects water cold sleeve below ash bucket, the outlet of water cooling its lower end has storage hopper, storage hopper bottom
Portion is equipped with form ash-valve, and form ash-valve is connected by decelerator with three asynchronous motors.
Described ash discarding bucket upper end is single radial cut, and lower end is dual openings, and dual openings connect respectively with a water cold sleeve upper end
Connect.
The connection suitable for reading that two described water cold sleeves pass through convergence termination and storage hopper.
The entrance position relative with the outlet of disposable dust remover of described ash discarding bucket.
Described disposable dust remover upper port is ring mesh cylinder, and lower end is irregular ash bucket, and ring mesh cylinder middle part has
Gravitational precipitator.
The utility model has the advantages that：It is electric by increasing a crawl reversion in form ash-valve electric control loop
Loop, is divided into " crawl on the spot " and " long-range crawl "：On the spot crawl can manually be operated beside disposable dust remover ash removal equipment,
When finding that form ash-valve putty does not turn, artificial operation reversion button makes form ash-valve positive and negative rotation back and forth, is stuck in form
Dust between ash-valve impeller and cavity can be discharged gradually；Long-range crawl can pass through software programming reality in PLC system
It is existing, motor rotation situation is monitored after remote activation dust removing system, cause motor to block up because of putty if detecting form ash-valve
Turn to shut down, then start reversion control loop operating, if still detecting motor rotation blockage shutdown after reversion, be again started up positive transmission control
Loop processed.Thus, dust removing system downtime just can be greatly reduced, greatly reduce unnecessary detaching equipment service work.Can
Ash-valve is solved with simply and easily and stop dust removing system because of putty, so as to avoid that the spy of dust removing system maintenance need to be dismantled
Point.

Specific embodiment
As shown in figure 1, a kind of cork dry quenching disposable dust remover dust removing system crawl inverts electrical control, at least include：Ash discarding
Bucket 1, connects water cold sleeve 2 below ash bucket, the outlet of the lower end of water cooling sleeve pipe 2 has storage hopper 4, and the bottom of storage hopper 4 is arranged equipped with form
Grey valve 3, form ash-valve 3 is connected by decelerator with three asynchronous motors.
The described upper end of ash discarding bucket 1 is single radial cut, and lower end is dual openings, dual openings respectively with a upper end of water cold sleeve 2
Connection.
The connection suitable for reading that two described water cold sleeves 2 pass through convergence termination 5 and storage hopper 4.
The entrance position relative with the outlet of disposable dust remover 6 of described ash discarding bucket 1.
The described upper port of disposable dust remover 6 is ring mesh cylinder 7, and lower end is irregular ash bucket 8, in ring mesh cylinder 7
There is gravitational precipitator 9 in portion
As shown in Fig. 2 ash discharge principle of the present utility model is：After dust removing system starts, three asynchronous motor three-phase electricities
Source is connected, and rotates according to rotating excitation field direction, drives form ash-valve 3 to rotate by decelerator, big of the lower end of water cold sleeve 2
Grain coke powder is endlessly discharged into storage hopper 4 with the rotation of form ash-valve 3 from lower outlet.
The startup of threephase asynchronous is divided into " on the spot " and " long-range " two kinds of operator schemes：Will operation when " on the spot " operating
Permutator on case is allocated to " on the spot ", presses start button, and contactor coil obtains electric main contacts closure motor and switches on power and turns
Dynamic, catalyst auxiliary normally opened contact closed-lock starts order.Stop button is pressed, contactor coil power-off, motor power breaks
Open and stop operating, catalyst auxiliary normally opened contact disconnects.The permutator on control box is allocated to into " long-range " during " long-range " operation,
Control contactor coil is come by PLC and obtains electric and power-off, so as to controlled motor start and stop, and then drive form ash-valve to rotate
Discharge coke powder.
