Description
Technical field
The present invention relates to thermal power generating technology field, be specifically related to a kind of transporting pulverized coal with exhaust gas device and
The vent pulverized coal handling system for coal fired power plant of this transporting pulverized coal with exhaust gas device is set.
Background technology
Vent pulverized coal handling system is mainly used in carrying weary gas for the burner of boiler in coal fired power plant.
The coal dust that coal pulverizer grinds first is stored in Pulverized Coal Bin, and the coal dust of boiler combustion is by giving
Powder machine is taken by Pulverized Coal Bin, and this pulverized coal preparation system is referred to as bin storage type pulverizing system.Through thin
Desiccant after powder separator separates is referred to as " weary gas ", and weary gas contains a small amount of coal dust
(10%-15%), more moisture, and temperature is relatively low；In order to protect environment and save energy
Source, weary gas does not allow to enter air.
Prior art has in warehouse formula pulverized coal preparation system two kinds of processing methods, a kind of processing method
It is used to pulverized coal conveying, referred to as transporting pulverized coal with exhaust gas；Another kind of processing method is to be sent directly into burner hearth combustion
Burning, now, weary gas also referred to as " tertiary air ", implements the system i.e. pulverized coal carried by hot air system of the method
System.
It is less that vent pulverized coal handling system is applicable to raw coal moisture, and volatile matter content is higher, it is easy to
The coal caught fire and burn, such as brown coal and bituminous coal.Therefore, when coal dust is prone to deposition, system
Also spontaneous combustion, blast etc. it are susceptible to.Visible, the requirement of explosion proof of vent pulverized coal handling system is higher.When
When using the bituminous coal or brown coal that fugitive constituent is higher, for the needs run, powder feeding bellows need to be set,
As: 4 corresponding 20 powder feeding airducts of Powder discharging fan, and the pulverizer air that every Powder discharging fan is corresponding
Manage non-same layer burner.During oepration at full load, need to put into operation 3 Powder discharging fans and 16 powder feedings
Airduct, now arranges air-supply bellows, can facilitate the adjustment of Powder discharging fan and powder feeding airduct.
At least there is techniques below problem in prior art:
During transporting pulverized coal with exhaust gas in prior art, the coal dust that weary gas is carried generally uses
The ature of coal that fugitive constituent is higher, easily there is the thing such as spontaneous combustion, blast when depositing in the ature of coal that fugitive constituent is higher
Therefore, so how avoid coal dust deposition during transporting pulverized coal with exhaust gas to become this area and treat harshly the skill of solution
Art problem.
Summary of the invention
The purpose of the present invention is to propose to a kind of transporting pulverized coal with exhaust gas device and this transporting pulverized coal with exhaust gas dress is set

Landing to after bellows 1, continues landing in row's tube cell 2 from the inner chamber of bellows 1.
As one preferably or alternatively embodiment, internal diameter size (this size of row's tube cell 2
Be preferably 10mm～100mm) be preferably less than powder feeding airduct 3 internal diameter size.Powder feeding airduct
The internal diameter size of 3 is preferably less than the internal diameter size in blast pipe road 4.Said structure is conducive to carrying
High weary gas and coal dust input bellows 1, and the efficiency of powder feeding airduct 3 is entered through bellows 1, and
And too much weary gas can be avoided to flow out in row's tube cell 2 with coal dust.
As one preferably or alternatively embodiment, the number of powder feeding airduct 3 is 2～20,
It is preferably 10.Certainly, the number of powder feeding airduct 3 can set according to being actually needed of burner
Put any number of.Powder feeding airduct 3 is preferably evenly distributed on bellows with the link position of bellows 1
The top 11 of 1.
As one preferably or alternatively embodiment, transporting pulverized coal with exhaust gas device also includes Powder discharging fan
(not illustrating in figure), the air outlet of Powder discharging fan (can lead to the flow inlet in blast pipe road 4
Piping) it is connected, the air inlet of Powder discharging fan (can lead to the discharge of row's tube cell 2
Piping) it is connected.Also need to be connected with weary source of the gas during the actual application of the air inlet of Powder discharging fan
Logical, to gather, to absorb weary gas.Powder discharging fan be weary gas and coal dust flowing and through blast pipe
Road 4, bellows 1, the most finally flow to powder feeding airduct 3 and provide power.Meanwhile, Powder discharging fan
The coal dust that the discharge of row's tube cell 2 is collected can also be reused.
The vent pulverized coal handling system for coal fired power plant that the embodiment of the present invention provides, including the present invention
The transporting pulverized coal with exhaust gas device that arbitrary technical scheme provides, wherein: the powder feeding airduct of transporting pulverized coal with exhaust gas device
