Description
Technical field
The utility model relates to a kind of stone coal environment protection emission sealing gathering-device.
Background technology
In thermal power generation corporations, medium-speed pulverizer is widely used in more than 300,000 kilowatts in the generating set, and in medium-speed pulverizer system running, the discharge capacity size of stone coal depends primarily on electric ature of coal amount and coal pulverizer dynamic and static ring running status.The smooth and easy continuous degree of stone coal discharging directly has influence on the running status of coal pulverizer, even can directly influence the running status of generating set; So the stone coal emission problem of medium-speed pulverizer has become boiler of power plant specialty regular maintenance major tasks content, accounts for more than 45% of everyday devices maintenance.
In the medium-speed pulverizer system of the existing operation of China, the discharging of stone coal is the largest source that causes coal pulverizer workshop dust pollution all the time, has seriously disturbed the power plant to carry out production strictly in line with rules and regulations.Use wider medium-speed pulverizer at present, its deslagging mode all is to adopt the box dreg removing system of buffering basically, and discharging is manually cleared on the spot, ash gate leaks and the phenomenon that leaks outside in just existing after operation a period of time, because the factor of coal pulverizer design itself and ature of coal influence, stone coal and removing slag amount increases, and stone coal and removing slag entrance door and outlet portal are frequently opened, cause ash gate serious wear, door-plate distortion, form jam, make that the door-plate open and close are not in place, cause seriously and leak out.Barotropic gas during deslagging in the slag case carries a large amount of dust, the severe contamination surrounding environment, so the problem that will solve is all puted forth effort by the numerous thermal power generation corporations of stone coal discharging becoming.
It is in the outlet of medium-speed pulverizer deslagging deslagging inlet valve, buffering dreg-storing box, deslagging outlet valve to be set in order that existing medium-speed pulverizer cushions box dreg removing system, dividing into opened type stone coal shifts bucket or establishes opened type stone coal dolly, the stone coal is in the end slagged tap, airborne dust is strong in the transfer process, boiler factory building condition of work very severe has a strong impact on the power plant safe operation and carries out production strictly in line with rules and regulations.And residual cake valve is poorly sealed, and it is serious to leak outside, and after buffering dreg discharging box slag notch opened wide, directly deslagging (containing dust) was to uncovered transfer bucket, and dust raising phenomenon is extremely heavy, again because the transhipment bucket is uncovered dolly, slag tap and transport process in dust from flying, contaminated environment.Because stone coal and removing slag amount is bigger,, influences coal pulverizer and normally move so artificial deslagging can't shift the stone coal rapidly.
The utility model content
The utility model provides a kind of stone coal environment protection emission sealing gathering-device, and described device adopts sealing to collect, and has avoided contaminated environment such as dregs, dust, therefore not only environmental protection, and the deslagging transport speed is fast, has effectively improved production environment, has improved operating efficiency.
For realizing above purpose, by the following technical solutions:
A kind of stone coal environment protection emission sealing gathering-device, its composition comprises that its composition comprises that stone coal transport box, pneumatic brake plate valve, ground platen, guide reducing tube connector, pneumatic brake plate valve, interface connect rectangular flange and malleation switch board, it is characterized in that, below the described stone coal transport box wheel is installed, be connected with the maintenance sealed compartment above, there is the pneumatic brake plate valve guide reducing tube connector upper end, between lower end and the maintenance sealed compartment pneumatic brake plate valve is arranged, and on the malleation switch board indicator lamp is arranged.
At first, the whole stone coal collecting process of described sealing gathering-device is the continuous uninterrupted process, and therefore, it is long-pending can not produce the stone dump in the stone coal bunker of coal pulverizer, lower the wearing and tearing of mechanical parts such as scraper plate, skirt cover to greatest extent, effectively prolonged its cycle of operation.Be separately installed with pneumatic brake plate valve and pneumatic slide valve at guide reducing tube connector, control the switching of two slide valves by the circuit of switch board, therefore equipressure, the sealing discharging of stone coal have been realized, the sealing measure that connects material of device mainly is made up of sealed compartment assembly and stone coal transport box section interface, both compress sealing by biserial Direct Travel cylinder, and sealing is reliable.
In addition, under the connection of the interface under described coal pulverizer rectangular flange, designed two special-purpose residual cake valves of the using and the reserved, guaranteed that the coal pulverizer system does not tightly leak in work and tapping process; Have seal cover board at residual cake valve, design interfaces such as material level, RTD, negative pressure, water spray on the cover plate, the cover plate lower plane is provided with the hermetically-sealed construction of special (purpose) rubber sealing ring; Seal cover board lower space design specialized promotes and the sealing hold-down mechanism; Ground Design Orientation mechanism; The stone coal bin is designed to portable stone coal bin, and the ground platen is arranged under it, is compressed by positioner and the lifting of lift-off seal device location during work, does not leak in the assurance work.
In stone coal transport box both sides load-carrying fork truck turner is installed, is convenient to the transportation of fork truck and topples over.If the special-purpose slag of design field outside the coal pulverizer factory building, other design specialized promotes tilting device in the slag field, can make toppling over of stone coal convenient.
