Description
Technical field
The invention belongs to the slag equipment technology field of transport, be specifically related to a kind of novel horizontal link chain formula slag remover.
Background technology
Lime-ash after the reduced fuel oil burning must regularly be removed; With the normal operation of keeping boiler with keep carrying out production strictly in line with rules and regulations of boiler room; The method of removing lime-ash has artificial slagging-off and special equipment slagging-off, and artificial slagging-off labour intensity is big, when extinguishing lime-ash, can produce a large amount of flue gases that contaminative is arranged; Human body is caused certain injury; Therefore except be not more than at evaporation capacity 0.5 ton/time boiler on also use the artificial slagging-off, generally all adopt special slag removal equipment slagging-off, be divided into mechanical deslagging, water sluice and pneumatic ash handling by method;
The slag removal equipment of station boiler is one of all equipment visual plants in power station; Along with the increase day by day of boiler capacity, the boiler that uses high grey matter faulty coal is more and more, and the lime-ash quantity discharged is also increasing; For example; A 200MW unit 670t/h boiler using brown coal, the grey quantity of slag of discharging every day is about the 150-200 ton, so the slagging-off problem of boiler seems and becomes more and more important.How broken, discharge, carry these lime-ash, should compliance with environmental protection requirements, energy savings, water source, consider the comprehensive application of lime-ash again, will be that one of significant problem that solves is badly in need of in power plant.Therefore, can correct choice, the slag removal equipment of the good boiler of design and use, very big to safety, the economical production relation of power plant.
The Slagging Characteristics of meltbility of coal ash (ash fusion point) and rheological behavior (viscosity-temperature characteristics) and coal ash has substantial connection, uses the power plant of clinkering property than strong coal, and its slag removal equipment problem that occurs that is in operation is more.For example: disconnected pin, chain rupture, folded chain take place in scraper-type dragveyer regular meeting, chain slides down and bite, quick abrasion, the big cinder of difficult discharge, and scraper plate is yielding; The piston cylinder of a wet type water seal slag removal equipment and the seal ring of lime-ash gate are aging, and gate poor sealing performance, deslagging are blocked by the slag ash often, do not open; The roll-type slag crusher is stuck by big slag; The tup of paddle type mill slag crusher is ground away, is come off, body vibrations and grid are prone to by the lime-ash obstruction etc.The boiler lotus operation of must lightening the burden immediately when the problems referred to above take place, timely trouble-shooting sometimes even need blowing out to handle, is removed with the disintegrating slag equipment mechanism that damages malfunctioning, forms the open continuous slagging-off of furnace bottom.Make the furnace bottom entering burner hearth that leaks out in a large number, it is stable to influence the stove internal combustion, and steam temperature raises; Heat efficiency reduces, and the blower fan power consumption increases, and cinder has the very high porosity and bigger face area in lime-ash; When ash erosion was serious, nearly the bulk high temperature cinder of 800-900 degree was difficult for granulation and fragmentation, and many big slags drop suddenly and will produce instantaneous vaporization in the water seal head; Cause air pressure to gather and increase, set off an explosion, visible; The quality of slag removal equipment will directly have influence on the normal operation of boiler.
The water condition of power plant and an ash size are the preconditions that decision lime-ash disposal system is selected form (dry type or wet type cinder-removing system, dry type circulating water or closed circle water system) for use.Oil in the water of ash-slag delivery and grease, whether the water quality criteria such as solid, pH value that suspend surpass the environmental regulations standard entirely, also be select to remove in the slag system one of the subject matter that will consider.
More than these problems will directly influence the pattern etc. of storage, conveying and disposal system of capacity and type selecting and lime-ash of design, deslagging mode, the slag crusher of slag removal equipment.The design of slag removal equipment and type selecting are also relevant with the distance of the distance of the integral layout of Boiler House and ashery ground and power plant, highland etc.The operation of power plant facts have proved; The slag removal equipment of boiler and the operation of boiler are closely related, and only guaranteed slag removal equipment normally moves, and could guarantee boiler so that the normal operation of whole unit.
