Abstract
Disclosed is a cabin-pump-free numerical-control dense-phase pneumatic ash conveying system. A cabin pump and feeding and discharging valves of an original conveying system are omitted, the ash conveying system is simplified, the maximum ash conveying amount of each set of conveying system body is set, the maximum conveying amount of each ash storage hopper is times of the ash falling amount of the ash storage hopper, and ash feeders of a plurality of the ash storage hoppers perform conveying alternatively in the maximum ash conveying amount. The dense-phase conveyed safe ash gas ratio is matched with the stable quantitative ash conveying amount, so that high-level alarm of the ash storage hoppers and ash conveying pipeline blocking can be prevented, and the ash convey system can operate under a safe and economic state.
Description
Technical field
The present invention relates to a kind of no silo pump type numerical control concentrated phase Pneumatic ash conveying system.
Background technology
Up to now, in commercial production, the conveying of fly ash and use, majority is to adopt storehouse pump and inlet valve thereof as the major equipment of Pneumatic ash conveying, there is system complex in this ash-transmission system, occurs the warning of storage ash bucket high charge level, ash conveying pipe plugging, the high shortcoming of serious, the defeated ash power consumption of pipe wear easily.For overcoming these shortcomings, the existing silo pump type Pneumatic ash conveying system reform is become no silo pump type numerical control concentrated phase Pneumatic ash conveying system, through improved ash-transmission system, can guarantee Pneumatic ash conveying smooth operation under safety, environmental protection, energy-conservation state.
Summary of the invention
The objective of the invention is: cancel storehouse pump and the charging/discharging valve thereof of former ash-transmission system, simplify ash-transmission system, improve the safety and economy of ash-transmission system operation.
The technical scheme of taking is: with coal-burning power plant's electric formula dust exhaustor I electric field 4 storage ash buckets (1) serial connection ash-transmission system being arranged is example, it is transformed into no silo pump type numerical control concentrated phase Pneumatic ash conveying system, the technical scheme of its transformation is: storehouse pump and the charging/discharging valve thereof of cancelling former ash-transmission system, with the quantitatively defeated ash amount operation of ash amount as each machine supplying powder (5) that fall of 4 times maximum in 4 storage ash buckets, can avoid storing up ash bucket and the high charge level warning occur, be machine supplying powder and the quantitatively operation of the unobstructed ground of ash conveying pipe (8) energy of guaranteeing defeated ash, installing maintenance insertion plate door (3) before machine supplying powder, mesh screen cleaning plant (4) and each the storage ash bucket bottom all install low level-sensing device (2), pressing the duration of every machine supplying powder continuous working or the ash position of storage ash bucket arrives when hanging down material level, the programming control machine supplying powder switches to next machine supplying powder wheel in proper order by the ash bucket operation and changes jobs, make machine supplying powder always remain on the down quantitative concentrated phase operation of maximum defeated ash amount, can lower defeated grey unit consumption, fall into mixer (6) before at fly ash, machine supplying powder can be monitored out the instantaneous and cumulative discharge of defeated ash, resistance and quantitative operational throughput according to delivery duct, be in operation and just can match the air supply participation operation that compressed air tube (7) should mate, determine that no silo pump type numerical control concentrated phase Pneumatic ash conveying system remains on the stable grey gas of concentrated phase safety than moving down, the plugging phenomenon just can not take place in ash conveying pipe, the flow velocity of ash conveying pipe is also minimum, lowered the wearing and tearing of pipeline, minimizing causes the pollution of flying upward dust because of wearing and tearing.
Description of drawings
The accompanying drawing of no storehouse pump type numerical control concentrated phase Pneumatic ash conveying system is according to 4 storage ash buckets serial connection ash-transmission systems are arranged, and system is made up of following components:
1. low level-sensing device 3. maintenance of storage ash bucket 2. storage ash buckets are failed grey compressed air piping 8. ash conveying pipes with insertion plate door 4. mesh screen cleaning plants 5. machine supplying powders 6. mixers 7.
The specific embodiment
In the Figure of description: with coal-burning power plant's electric formula dust exhaustor I electric field the serial connection ash-transmission system of 4 storage ash buckets (1) being arranged is example, it is transformed into no silo pump type numerical control concentrated phase Pneumatic ash conveying system, cancel storehouse pump and the charging/discharging valve thereof of former ash-transmission system, with the maximum of 4 times in ash bucket of the storage defeated ash amount of ash amount as each machine supplying powder (5) that fall, can avoid storing up ash bucket and the high charge level warning occur, for guarantee machine supplying powder and ash conveying pipe (8) can be unobstructedly with the quantitatively operation of ash amount that falls of 4 times maximum, installing maintenance insertion plate door (3) before machine supplying powder, mesh screen cleaning plant (4) and each the storage ash bucket bottom low level-sensing device (2) all is set, pressing the duration of every machine supplying powder continuous working or the ash position of storage ash bucket arrives when hanging down material level, the programming control machine supplying powder switches to next machine supplying powder operation in turn in proper order by ash bucket, make defeated ash amount always remain on maximum defeated ash amount quantitative smooth operation down, can reduce defeated grey unit consumption, carrying fly ash to fall into mixer (6) before, the quantitatively defeated ash amount of fly ash has been monitored out the instantaneous and cumulative discharge of defeated ash by machine supplying powder, resistance and quantitative operational throughput according to delivery duct, be in operation and just can match the air supply of compressed air tube (7), remain on the grey gas of the safety that matches than operation down, the plugging phenomenon just can not take place in ash conveying pipe, the flow velocity of ash conveying pipe is also minimum, and minimizing pipe wear and the flying dust that causes because of wearing and tearing pollute.
Claims (1)
1. be example with the serial connection ash-transmission system with 4 storage ash buckets (1), the reformation characteristics of its system is: storehouse pump and the charging/discharging valve thereof of cancelling former ash-transmission system, with 4 times of storage ash bucket maximums ash amount quantitatively defeated ash amount as each machine supplying powder (5) that falls, for guarantee that machine supplying powder and ash conveying pipe (8) can move unobstructedly, installing maintenance insertion plate door (3) before machine supplying powder, low level-sensing device (2) is all installed in the bottom of mesh screen cleaning plant (4) and each storage ash bucket, complying with the time of every machine supplying powder continuous working or the ash position of storage ash bucket arrives when hanging down material level, the programming control machine supplying powder switches to next machine supplying powder operation by storage ash bucket rotation, fall into mixer (6) before at fly ash, machine supplying powder can be monitored the instantaneous and cumulative discharge of ash-transmission system, just can match the air supply that compressed air tube (7) should be provided and delivered, ash conveying pipe can stably be moved under the grey gas ratio of the safety of concentrated phase.
