A kind of thin block apparatus of bag filter ash bucket

Technical field

The utility model relates to gas cleaning processing technology fields, dredge stifled dress in particular to a kind of bag filter ash bucket It sets.

Background technique

The data that China National Bureau of Statistics of China announces recently show that 2017, Chinese generated energy steady-state growth, power supply architecture was still Need adjusting and optimizing.Data show that 2017, China's 6,495,100,000,000 kilowatt hours of total power generation increased by 5.9% than last year, speed increasing ratio Last year accelerates 0.4 percentage point.From about 5.0 trillion kilowatt hours in 2012 to nearly 6.5 trillion kilowatt hour in 2017, in recent years Come, Chinese generated energy realizes the stable development of average annual growth by 5.4%.

From the point of view of power supply architecture, the growth of last year thermoelectricity is more steady, and proportion declines year by year.

Data show that 2017, Chinese 4,662,700,000,000 kilowatt hour of thermal power output increased by 5.1% than last year, and speedup is slower than Clean energy resource power generation growth rate.Thermoelectricity accounts for whole generated energy specific gravity and gradually declines since 2012, and 2017 are 71.8%, than Decline 6.3 percentage points within 2012.

Currently, Chinese thermoelectricity specific gravity has Tianjin, Shanghai, Beijing, Shandong, Anhui, Henan, river in 90% or more area Soviet Union, 8, Shanxi area, wherein Beijing is essentially fuel gas generation, and Tianjin, Shanghai Gas power generation account for thermoelectricity specific gravity on 1/6th left sides The right side, remaining area is mostly coal fired power generation, and power supply architecture needs to be advanced optimized.

Although the clean energy resourcies speedup such as water power, nuclear power, wind-powered electricity generation, solar power generation is significant, in the electric system in China, Thermal power generation specific gravity is still come out top.

The a large amount of dust processing that thermal power generation coal unit generates, present Treatment process is all made of electric precipitator, bag removes The mode of dirt device or electric bag mixed dust collector, bag dust collector therein are that dust is isolated with filter bag, and dust is fallen on ash bucket, so Grey library is transported to ash-transmission system afterwards.If grey headwall has dust, common two methods eliminate the dust in ash bucket: the first is Electric motor of shaker is housed on ash bucket, electric motor starting rapping ash headwall is attached to dust on grey headwall and is slipped to due to physical shock The defeated grey mouth of ash bucket, is seen off by ash-transmission system.

The second way is exactly to use air cannon device, and air cannon device is the thrust using compressed air, will be attached to Dust on ash bucket bulkhead blows off hopper bottom, then is delivered to grey library by ash-transmission system.

Both modes are to be transported to hopper bottom with physical force, from top to bottom by dust, but do not account for The case where being blocked to ash bucket ash hole, once the multiple factors shadows such as ash bucket wall heater failure can not start, live humidity is big It rings, dust scleroma is blocking, and no matter the blocking of ash bucket ash hole can not allow dust from grey quarrel export with which kind of method.

With first method, electric motor of shaker starting, grey quarrel blocking, dust accumulation, can more and more, ash bucket to grey quarrel The dust accumulation of ash hole and cannot be discharged, as electric motor of shaker constantly vibrates grey headwall, will cause the dust of ash bucket ash hole It agglomerates increasingly severe, the transverse pressure of grey quarrel is increasing, finally blocks ash bucket ash hole, and dust cannot be discharged.

With second method, when ash bucket ash hole blocks, compressed air is discharged in air bubble, because ash bucket is not closing system System, there are also air inlet and filter bags for top, so the strength that air bubble generates cannot generate the pressure of ash bucket from inside to outside, Bu Nengtong The defeated grey mouth of blocking, and the strength soot blowing that air bubble generates are washed in excess pressure open, dust since strength cannot export in ash bucket, Be whirled up, raise dust again can enter filter bag dedusting region, caused by filter bag adhere to dust it is more and more, add pulse After valve blowing, dust continues back at filter bag area after blowing off, if cannot be handled for a long time, can cause the thing that builds the pressure to bag dust collector Therefore.

So ash bucket ash hole, which keeps clear, provides safety guarantee for the operation of bag filter, to make ash bucket ash discharge Mouth keeps clear, and usual method is all with a drill rod to defeated grey mouth bottom poking dust, or arrives special ash poking mouth ash poking, this Kind of ash poking mode not only needs manually to arrive execute-in-place, but also dust has a higher temperature, ash poking leak it is improper can cause it is a series of Safety accident.
