Abstract
The utility model discloses a deslagging device of a boiler coal pulverizer in a power plant, which solves the technical problem that a traditional coal pulverizer needs to be carried out deslagging in a large quantity in time under the condition that the coal powder fineness of the coal pulverizer is controlled to the lower limit of a specified value of a standard. The deslagging device comprises a cobble coal bunker (4), a cobble coal suction tube (6), a material cutting hopper (7), a filtering suction tube (9) and a filtering hopper (10), wherein the cobble coal bunker (4) is communicated with the material cutting hopper (7) through the cobble coal suction tube (6); the material cutting hopper (7) is communicated with the filtering hopper (10) through the filtering suction tube (9); a material cutting hopper discharge valve (8) is arranged at the bottom of the material cutting hopper (7); a filtering hopper discharge valve (11) is arranged at the bottom of the filtering hopper (10); and a vacuum suction tube (12) communicated with a vacuum host machine is arranged on the filtering hopper (10). By using the deslagging device, the labor intensity is reduced, raised dust pollution is restrained, and the work environment surrounding a boiler is improved.
Description
Technical field
The utility model relates to a kind of slag-draining device, the slag-draining device of particularly a kind of thermal power plant coal pulverizer.
Background technology
In the thermal power plant for the wearing and tearing of the heating surface of controlling coal-burning boiler; directly effective control measure of often taking; control the coal pulverizer fineness of pulverized coal exactly; the coal pulverizer fineness of pulverized coal is controlled to the lower limit of rules setting; promptly 20%～25%, can make boiler heating surface can not occur because of four-tube leakage by the accident of forced-stopping machine.But the control of fineness of pulverized coal also can bring certain negative effect, and the wearing and tearing that are exactly coal pulverizer obviously increase, the coal pulverizer bed drain purge apparently higher than before bed drain purge during control 30% fineness of pulverized coal.Under unit large load operation operating mode, the timely deslagging of coal pulverizer has become normal operation that influences coal pulverizer and the subject matter that satisfies the boiler wear resistant requirement of explosion proof simultaneously.
Summary of the invention
The utility model provides a kind of boiler of power plant coal pulverizer slag-draining device to solve the coal pulverizer fineness of pulverized coal has been controlled to the technical problem that coal pulverizer under the situation of lower limit of rules setting needs in time a large amount of deslagginves.
The utility model overcomes the above problems by following scheme:
Boiler of power plant coal pulverizer slag-draining device, comprise stone coal bunker, stone coal suction tube, cut hopper, filter pipet and filtration hopper, described stone coal suction tube is connected together a stone coal bunker and a section hopper, described filter pipet will cut hopper and be connected together with the filtration hopper, be provided with a section hopper discharge valve in the bottom of cutting hopper, be provided with filtration hopper discharge valve in the bottom of filtering hopper, filter hopper and be provided with the suction vacuum tube that is communicated with the vacuum main frame.
On described stone coal bunker, be respectively arranged with stone coal bunker baiting valve, stone coal bunker benefit air-valve stone coal bunker feed valve and level-sensing device.
The utility model has reduced hand labor intensity, has suppressed dust pollution, has improved boiler working environment on every side.

Specific embodiment
Boiler of power plant coal pulverizer slag-draining device, comprise stone coal bunker 4, stone coal suction tube 6, section hopper 7, filter pipet 9 and filter hopper 10, described stone coal suction tube 6 is connected together a stone coal bunker 4 and a section hopper 7, described filter pipet 9 will cut hopper 7 and be connected together with filtration hopper 10, be provided with a section hopper discharge valve 8 in the bottom of cutting hopper 7, be provided with filtration hopper discharge valve 11 in the bottom of filtering hopper 10, filter hopper 10 and be provided with the suction vacuum tube 12 that is communicated with the vacuum main frame.
On described stone coal bunker 4, be respectively arranged with stone coal bunker baiting valve 1, stone coal bunker benefit air-valve 2 stone coal bunker feed valve 3 and level-sensing devices 5.
The utility model is a stone coal discharging negative-pressure pneumatic transmission system, and it utilizes the charging gear outlet under the coal pulverizer stone coal hopper, is connected to the hopper that cuts of vacuum equipment main frame by the main frame pipe network; The negative pressure that the vacuum equipment main frame produces is drawn into cutting in the hopper of vacuum main process equipment with the stone coal in the stone coal hopper.The vacuum equipment main frame cuts hopper can be in parallel with many coal pulverizer stone coal bunker outlets by the main frame pipe network, forms the discharging negative-pressure pneumatic transmission system.Stone coal discharging negative-pressure pneumatic transmission system is owing to use the vacuum equipment main frame as the power of carrying the stone coal, and the stone coal is by with the slag storehouse with cut in the seamless steel pipe that hopper is connected and carry, and is complete in airtight subnormal ambient, so environmental protection more; The conveying of stone coal is directly to aspirate from stone cinder storehouse, therefore can alleviate working strength of workers greatly; The suction of each each slag storehouse stone coal is to finish in 3-5 minute, and the transfer efficiency of stone coal also can improve greatly.Because this adopts on-the-spot present original vacuum power source, only install and cut hopper, filter hopper and pipeline, technical change is done in the slag storehouse of present use, so one-time investment is few.Being installed in the outdoor interior stone coal discharging of hopper that cuts is finished by existing means of transport in the factory.When hopper is full, can reaches feed hopper bottom to dump truck or other means of transport etc. and carry out discharging.
