Description
Technical field
The utility model relates to a kind of pulverized-coal collector, particularly a kind of Novel fine powder separator for 100MW～1500MW coal-burning power plant.
Background technology
In coal-fired power plant, separator is one of crucial treatment facility in pulverized coal preparation system, raw coal being processed into coal dust, and the qualified coal dust that it grinds out coal pulverizer is separated and sent into hearth combustion.Therefore, fineness degree and particle diameter that pulverized coal preparation system cyclone performance is just determining to send into the powder of hearth combustion distribute, and have influence on the wearing and tearing of efficiency of combustion, pulverized coal preparation system energy consumption, NOx discharge and the follow-up system equipment of boiler.
At present, China coal-fired power plant bin system because of the structural design of pulverized-coal collector unreasonable, the blast pipe of separator is generally all with shutter and blade, this has destroyed the separated space of separator greatly.In addition, more seriously blast pipe diameter is greater than separator shell cone section bottom powder outlet diameter Dx, this makes carrying under one's arms of powder very serious, caused the separating property of China's existing coal-burning power plant bin system pulverized-coal collector not high, make the coal dust content in tertiary air too high, the energy consumption increase of exhaust blower, draught fan impeller quick abrasion, life-span are short, and unit power consumption of coal pulverizing increases, the collection output of coal dust is few in Pulverized Coal Bin, and fineness of pulverized coal is bad.Have a strong impact on again boiler combustion, cause boiler flame center to raise, the economic benefit that desuperheating water consumption increases, exhaust gas temperature raises, discharged nitrous oxides exceeds standard ，Gei power plant has been brought great impact simultaneously.
Utility model content
The purpose of this utility model is, a kind of Novel fine powder separator for 100MW～1500MW coal-burning power plant is provided, and it has solved the problem of carrying under one's arms of the powder in separator, greatly reduce the back-mixing of coal dust, be conducive to the separation of particle, also increased in addition separated space, improved separative efficiency.
The technical solution of the utility model: a kind of Novel fine powder separator for 100MW～1500MW coal-burning power plant, comprise separator tangential entry, separator cylindrical housings, separator bottom cone, blast pipe, separator bottom hopper, separator tangential entry is located at the top of separator cylindrical housings, separator bottom cone is located at the bottom of separator cylindrical housings, blast pipe is located at the top of separator cylindrical housings, and separator bottom hopper is located at the bottom of separator bottom cone; The import department of separator bottom hopper is provided with the anti-mixed wimble device of separator; The inlet diameter of described blast pipe is 0.22～0.54 times of separator cylindrical housings diameter.
The aforesaid Novel fine powder separator for 100MW～1500MW coal-burning power plant, the entrance location of described blast pipe is positioned at following 0～2 meter of separator tangential entry base plate.
The aforesaid Novel fine powder separator for 100MW～1500MW coal-burning power plant, described blast pipe is cylindrical or conical.
The aforesaid Novel fine powder separator for 100MW～1500MW coal-burning power plant, does not install any despin mechanisms such as cross or blade in described blast pipe.
The aforesaid Novel fine powder separator for 100MW～1500MW coal-burning power plant, does not install shutter in described blast pipe.
Compared with prior art, the utility model, by the structure optimization to separator blast pipe, has been cancelled cross or blade isoracemization device, has also cancelled shutter.Greatly increase separated space, improved separative efficiency.Filtering out economic fineness of pulverized coal and the uniformity, is the coal dust that it is qualified that boiler combustion is provided and delivered, and improves boiler combustion effect, thereby improves the energy conversion efficiency of China coal-burning power plant, reduces the discharge of energy consumption and minimizing pollutant and NOx.
The separative efficiency of conventional separators is 84% left and right, and adopts structure of the present utility model separative efficiency can be brought up to 99%.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Being labeled as in accompanying drawing: 1-separator tangential entry, 2-separator cylindrical housings, 3-separator bottom cone, 4-blast pipe, 5-separator bottom hopper, the anti-mixed wimble device of 6-separator.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as the utility model being done to the foundation of any restriction.
Embodiment 1 of the present utility model: as shown in Figure 1, a kind of Novel fine powder separator for 100MW～1500MW coal-burning power plant, comprise separator tangential entry 1, separator cylindrical housings 2, separator bottom cone 3, blast pipe 4, separator bottom hopper 5, separator tangential entry 1 is located at the top of separator cylindrical housings 2, separator bottom cone 3 is located at the bottom of separator cylindrical housings 2, blast pipe 4 is located at the top of separator cylindrical housings 2, and separator bottom hopper 5 is located at the bottom of separator bottom cone 3; The import department of separator bottom hopper 5 is provided with the anti-mixed wimble device 6 of separator; The inlet diameter of described blast pipe 4 is 0.22 times of separator cylindrical housings 2 diameters, i.e. d=0.22D1 in figure.
The entrance location of described blast pipe 4 is concordant with separator tangential entry 1 base plate, i.e. H2=0m.Described blast pipe 4 is cylindrical.
Any despin mechanisms such as cross or blade are not installed in described blast pipe, shutter is not installed yet.
The entrance location of described blast pipe 4 is positioned at following 2 meters of separator tangential entry 1 base plate, the i.e. H2=2m of Fig. 2 middle and lower part.Blast pipe 4 is conical.
