Description
Technical field
This utility model belongs to thermal power generation unit SCR denitration device technical field, is specifically related to a kind of boiler SCR denitration
Bottom of device flying dust Automatic continuous discharger.
Background technology
Along with the raising requiring the fired power generating unit feature of environmental protection, current all of fired power generating unit all must be at boiler back end ductwork
SCR denitration device is installed afterwards.Flue gas can deposit due to a variety of causes, the part flying dust in flue gas through SCR denitration device
In ash bucket bottom SCR denitration device.The flying dust of this part deposition must be removed in time, otherwise can affect the normal fortune of equipment
OK.Conventional reset mode is by fly ash carry extremely ash storehouse by pneumatic ash transmitting system.But air-transport system include storehouse pump,
The wear-resisting ash conveying pipe of distance, fluidized wind system, flapper etc., equipment investment and operating cost are the highest.
Summary of the invention
The technical problems to be solved in the utility model is to provide flying dust Automatic continuous row bottom a kind of boiler SCR denitration device
Go out device.
This utility model solves above-mentioned technical problem by the following technical programs:
Flying dust Automatic continuous discharger bottom a kind of boiler SCR denitration device, including ash bucket, manually gate valve, defeated ash
Pipeline and the flue of connection cleaner unit, it is characterised in that
Described ash bucket is infundibulate, is provided with ash discharging hole in the bottom of infundibulate ash bucket；
Described ash discharging hole is connected by ash conveying pipe and flue；
Described ash conveying pipe is provided with manually gate valve at ash discharging hole.
As optimization, also Pneumatic gate valve, described Pneumatic gate valve is arranged on the rear portion of manually gate valve；
As optimization, described ash conveying pipe accesses the position of flue near cleaner unit entrance；
As optimization, described ash conveying pipe is that 30 ° of angles access flue along flow of flue gas direction and flue centrage；
As optimization, described ash conveying pipe is set to vertical lower slope section in tobacco pipe exit, more defeated by horizontal feed end
Deliver to flue；
As optimization, the turning point of described ash conveying pipe all uses bend pipe to connect.
This utility model does not lay the equipment such as storehouse pump, fluidized wind system, flapper, the wear-resisting ash conveying pipe of distance, equipment
Investment and operating cost are substantially reduced；Flue before ash bucket is connected to cleaner unit entrance bottom SCR denitration device, fed distance
Short, the wear-resisting ash conveying pipe of needs is shorter；From absolute altitude, the absolute altitude of SCR denitration device outlet at bottom is typically than cleaner unit
High several meters of entrance, by ash conveying pipe is arranged to only horizontal segment and the form of vertical lower slope section, resistance is little is conducive to flying dust
Conveying；Ash conveying pipe is that 30 ° of angles access flue along flow of flue gas direction and flue centrage, and the resistance of inflow is little, to cigarette
In road, the flow of flue gas itself is little；Ash conveying pipe is connected to the flue near cleaner unit entrance, and flying dust is vertical after mixing with flue gas
I.e. enter cleaner unit, will not in flue dust stratification.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram；
In figure: 1, ash bucket；2, manually gate valve；3, Pneumatic gate valve；4, ash conveying pipe；5, flue；6, cleaner unit.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, it is further elaborated on content of the present utility model.
Flying dust Automatic continuous discharger bottom a kind of boiler SCR denitration device, including ash bucket 1, manually gate valve 2, gas
Dynamic slide valve 3, ash conveying pipe 4 and the flue 5 of connection cleaner unit 6,
Described ash bucket 1 is infundibulate, is provided with ash discharging hole in the bottom of infundibulate ash bucket；
Described ash discharging hole is connected by ash conveying pipe 4 and flue 5；
Described ash conveying pipe 4 is provided with manually gate valve 2 and Pneumatic gate valve 3 at ash discharging hole；Described pneumatic brake
After plate valve 3 is located at manually gate valve 2；
Time properly functioning, twice slide valve is the most normally opened, and Pneumatic gate valve 3 can play shutoff effect, manual flashboard with quick acting
Valve 2 can play shutoff effect when Pneumatic gate valve 3 overhauls；
Described ash conveying pipe 4 accesses the position entrance near cleaner unit 6 of flue 5, prevents flying dust dust stratification in flue 5；
Described ash conveying pipe 4 is set to vertical lower slope section 41 in tobacco pipe 1 exit, then is delivered to by level transportation section 42
Flue 5；Described ash conveying pipe 4 is that 30 ° of angles access flue 5 along the centrage in flow of flue gas direction Yu flue 5；So flying dust stream
The resistance entered is minimum, minimum to the flow of flue gas itself in flue 4；All turning points of ash conveying pipe 4 all use bend pipe
Connecting, the resistance ratios elbow of bend pipe is little, and wearability is more preferable.
Flying dust in ash bucket bottom SCR denitration device 1 is fed directly to cleaner unit by ash conveying pipe 4 by this utility model
In flue 5 before 6 entrances, because the negative pressure in flue 5 is higher than the negative pressure in SCR denitration device, flying dust can Automatic continuous from
Bottom SCR denitration device, ash bucket 1 flows into flue 5 by ash conveying pipe 4 and mixes with flue gas, and mixed flue gas immediately enters
Cleaner unit 6.
Comparing with legacy equipment, this utility model does not has storehouse pump, fluidized wind system, flapper, the wear-resisting ash pipeline of distance
The equipment such as road, equipment investment and operating cost are substantially reduced；And before bottom SCR denitration device, ash bucket is connected to cleaner unit entrance
Flue, fed distance is short, and the wear-resisting ash conveying pipe of needs is the shortest, and cost is the highest.
In addition, from plant and equipment absolute altitude, bottom SCR denitration device, the absolute altitude of ash bucket outlet is typically than cleaner unit 6
High several meters of entrance, can be arranged to ash conveying pipe only vertical lower slope section and the form of level transportation section, utilize negative pressure and weight
Power makes flying dust enter ash conveying pipe, and recycling negative pressure carries at level transportation section, and flow passage resistance force of waterproof is little is conducive to the defeated of flying dust
Send.
When design, it is that 30 ° of angles access flues, flying dust stream by ash conveying pipe along flow of flue gas direction and flue centrage
The resistance entered is little, little to the flow of flue gas in flue itself, does not affect the normal work of cleaner unit.And ash conveying pipe connects
To near the flue of cleaner unit entrance, flying dust immediately enters cleaner unit after mixing with flue gas, will not in flue dust stratification.
