With the enhancement of environmental protection standards by government and the strengthened awareness of comprehensive utilization of fly ash. it has been a current development trend that power plants shift the hydraulic ash to transfering ash. Recent years, the conveying of dry ash mostly is done by silo pump, but considering the current operation situation, using silo pump can result in polluting environment, wasting resources and bringing inconvenience to store and transport coal ash, however Gongyi Machinery Factory develops and produces LFB series of Material Pump Sealing which is characterised by low wind pressure, simple operation, small amount of maintenance,etc. Such equipment is widely used in the industry of Electricity, Aluminium, Cement, Chemical and is the ideal equipment for conveying kinds of powder material.
The Problem Existing in Single silo-pump, Negative Pressure transporting of fly-ash.
No.1: Large power consumption, Severely worn out
Due to the fact that Silo-pump adopts 0.4Mpa-0.6Mpa high pressure air supplier, pipeline elbow is severely worn out,especially the discharge valve, inlet valve, exhuast valve,which often get stuck, so it needs weiding repair, frequent change, plus, the high cost of wear maintenance of aerodynamic big three pieces, workers also need to climb on the pump body to repair whose temperature is high and working condition is tough, so it challenge the labour force.
No.2: Complicated operation
Because silo pump employ material level and automatic time control. Control console have complex wiring, if any thing happen, a few professionals from three departments involving Electric, Thermotechnical and Ash overhaul, which delay its maintenance time and bring troubles to management,then normal production has difficult going smoothly.
No.3: Do Harming to environment
Because of flaws mentioned above, in order to make sure its operation as a result that repair many times, equipments all over leak ash, bring harms to plant environment and surrounding the living environment and exert a serious influence on civilized production.
No.4: Bad Influence on Comprehensive Utilization of fly ash
In order to implement comprehensive utilization of fly ash, industry invest quite large money on fly-ash production line, but because of the frequent damage of conveying system, it can not guarantee the normal production of air separation system, some ash pipe even can not discharge and influence the ash supply from user,more than that, the image and benefits of industry is damaged.
No.5: Have influence on the normal production of ash pond
Due to the design of ash classified removel, after the damage of silo pump, you can only choose water to wash down the ash to ash pond, which cause the shortage of the water, that is, the water supply tension, besides, owing to the small fineness of ash, it can be a waste because it is easy to lead to the clog of the pipeline and the engine-grease of the valve and ash pump pipe, and then the whole ash washing system is damaged seriously.
No.6: Although negative pressure conveying have small influence of wear, after years using, air blower cannot work efficiently to remove the ash with the reason that its gradually lowing blowing rate.
the Advantage of using Material Pump Sealing
No.1: Equipment need small investment, the working amount of one set of material pump sealing is equal to that of two set of silo pump, so it greatly decrease the equipment invest.
No.2: Gas pressure that material pump sealing need is 0.04Mpa-0.01Mpa,it lower gas supply pressure, save gas consumption, meanwhile, it reduces the motor power.
No.3: it reduces the cost of maintenance, this system once experiences the installation and debugging of commissioning, it basically need no manual operation, need no amount of maintenance, the repairman just need to inspect it periodically.
No.4: Low-pressure conveying, equipment with good quality of sealing ,reliable operation, no situation of clogged pipe,more importantly, it is environmental-friendly.
Structure and working principle
Material pump sealing is composed of diffusion chamber, pump body, movable duct, performing mechanism, etc. Low pressure air pass through duct, pump body and then enter
diffusion chamber.When high speed airflow pass the pump body, it gasify the material around the nozzle, the airflow in the diffusion chamber from nozzle have shaped into partial negative pressure in the diffusion chamber of nozzle, and suck the gasified material to conveying pipe, then raised to emptying point by high speed airflow. Its structure is showed in the diagram.
the Cost Comparison between single silo pump and material pump sealing
No.1: the annual cost saving (20m3 air compressor, silo pump need one set of Roots Blower,power:90Kw, efficiency: 80%, annual working hour: 6000hours,electricity price: 0.28 CNY). the annual electricity cost of single silo pump: 2*132*0.8*6000*0.28=350,000 CNY
Annual electricity cost of material pump sealing: 1*90*0.8*6000*0.28=1210,000 CNY
so the cost you can save by using material pump sealing is 2290,000 CNY
No.2: Operation cost saving: 13+5-2=160,000 CNY
No.3: the equipment investment reduced: 20-(6.8*2)=6.4
As the figure above show: Replacing six set silo pump by two set material pump sealing can save you more than 300,000 CNY, it not only reduce the labour intensity and increase economical benefits, but also protect our working environment.

Installation, Operation and Maintenance
It is proper for material pump sealing to be installed at the bottom of material warehouse,it has to be fixed tight, so does the air inlet pipe and air discharge pipe, meanwhile,it has to make sure that the duct is on the horizon and exert seal processing on kinds of joints to ensure that they are air-proofs.
When you use the new launch of pump or you change material that you convey, firstly, you should put enough lubricant to the external cavity of movable duct, then adjust movable duct via performing mechanism to change the distance between the nozzle and sprinkler, and choose a relatively ideal position by debugging, at the same time,
mark down the scale label, and start normal working,when you want power off, you should first close the nozzle and sprinkler and make sure there are no material in the pipe, then you can stop the wind .
Material pump sealing can work normally, only when charge level attain a certain level, if charge level is lower than a certain value, the amount of conveying will be reduced, if something suddenly happen, like shortage of gas and some others, which get the pipe stuck, you should first close the nozzle and sprinkler and then blow it untill the pipe is open.
Conclusion
In the field of thermoelectricity industry, single silo pump give way to material pump sealing is the inevitable result of scientific and technological development. We can forsee that this technology will replace silo pump and take the leading place in the thermoelectricity industry in the near future and the comprehensive utilization of fly ash is up to a new level, it can create more economical and social benefits for industries.
