Description
Technical field
The utility model relates to the treatment technology of economizer ash, especially a kind of delivery system of economizer ash.
Background technology
Economizer is the parts that are arranged in heated feed water in the boiler back end ductwork, and its effect is the part heat that absorbs in the boiler tail flue gas, reduces funnel temperature, with fuel saving.Therefore the economizer ash have temperature height, particle thick, be difficult to long characteristics of carrying apart from strength, past is normal because the delivery system design is unreasonable, be delivered to factor affecting such as grey storehouse distance is far away, system's conveying energy consumption height, and operational effect is not ideal, usually has problems such as plugging, system's air consumption is big, the wearing and tearing pipeline is serious to occur.At present, the delivery system of economizer ash is delivered to the flying dust storehouse usually, because the economizer ash particle is thicker, it is far away that strength is delivered to grey storehouse distance, and this system cost is big, conveying energy consumption is higher, and the cost costliness can not satisfy the production needs.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of simple in structure, easy to use, fed distance is short, and is reliable, the delivery system of economizer ash with low cost, the delivery system of this economizer ash can solve the economizer flying dust and be difficult to the difficult problem that strength is carried.
The technical solution adopted in the utility model is as follows:
The delivery system of economizer ash of the present utility model, comprise the slag well, the other dry-type slag extractor that is provided with of described slag well, described dry-type slag extractor is sent to material in the bucket elevator, described bucket elevator is sent to material in the slag storehouse, the top in described slag storehouse is provided with bag dust collector, and described slag storehouse is connected simultaneously with the bottom of a plurality of economizers storehouse pump, and a plurality of economizers storehouse pump is connected on the source of the gas simultaneously.
Because the economizer ash particle is thick, proportion is bigger, the system that has adopted said structure to form, make fed distance shorten greatly, system's air consumption is little, the wearing and tearing pipeline is little, owing to be provided with bag dust collector at the top in slag storehouse, make that the maximum exhaust air rate of air suctiton ventilator is exactly the instantaneous maximum free air capacity of calculating, consider the variation of tolerance, this air suctiton ventilator need dispose the stepless time adjustment device, therefore by the stepless time adjustment of bag dust collector realization to tolerance, overcome the technical barrier in the industry, promptly when adopting gas delivery economizer ash, needing in the unimpeded and slag storehouse of the terminal air-flow of airflow line can't realize the difficult problem of deposit material.Therefore the delivery system by economizer ash of the present utility model, when can guarantee that the terminal air-flow of steam line is unimpeded, material deposit with the slag storehouse in, because this kind mode of movement fed distance shortens greatly, not only reliable, its duct length and the required pressurized air consumption of operation also reduce greatly, can save a large amount of over-the-road expenses and initial cost, this design system has become the best mode that present economizer ash is carried, and in industry this system also has extraordinary directive significance.
The delivery system of economizer ash of the present utility model, the top in described slag storehouse is provided with the vacuum pressure Dump valve.
Owing to adopted said structure, consider breakdown of equipment or be in an emergency, at slag Cang Ding the pressure vacuum Dump valve is set, assemble to avoid slag storehouse internal pressure or vacuum, thereby guarantee the safety used.
The delivery system of economizer ash of the present utility model, the ash pipeline of described economizer storehouse pump enter the slag storehouse and adopt the termination rack mode.
Owing to adopted said structure, the termination rack mode is adopted in ash pipeline slag input storehouse at economizer storehouse pump, can effectively avoid the direct slag input of economizer ash pipe storehouse, the inner eddy flow that forms in the slag storehouse, thereby can collect and store dried slag and economizer ash better, and the smooth operation of controlling air inlet of slag storehouse and exhaust better.
The delivery system of economizer ash of the present utility model, described source of the gas comprise instrument air system and ash disposal air compressor system, and described instrument is parallel to same steam line with air system and ash disposal air compressor system, is connected on the pump of a plurality of economizers storehouse.
Owing to adopted said structure, calculate and pass in and out the total strength balance of dry residue chamber, remaining in the dry residue chamber is that little negative pressure is very important, is the system that adopts the air cooling type slag drying machine to slag system especially, increase with the air quantity of avoiding this system to enter burner hearth, reduce boiler combustion efficiency.Therefore, air inlet: consider that mainly the economizer strength is delivered to the tolerance and the time in slag storehouse, also will consider the free air capacity and the time of discharging machine in bulk in addition.Exhaust: tolerance and the time that the economizer strength is carried the exhaust slag input storehouse of slag input storehouse, discharging machine in bulk is got rid of in main consideration, will consider the displacement tolerance (continuously) in dried slag slag input storehouse in addition.So adopt instrument in parallel with the ash disposal air compressor system to a plurality of economizers storehouse pump air feed, guarantee the normal operation of delivery system of this economizer ash and the good result of carrying the economizer ash with air system.
The delivery system of economizer ash of the present utility model, the ash pipeline between described economizer storehouse pump and the slag storehouse is provided with slip joint.
Owing to adopted said structure, can pass through this slip joint, control economizer storehouse pump in the slag storehouse for ash, make negative-pressure balancing in the slag storehouse, the safety of assurance use.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1. the delivery system of economizer ash of the present utility model, simple in structure, easy to use, fed distance is short, and is reliable, with low cost;
2. the delivery system of economizer ash of the present utility model, can effectively avoid the direct slag input of economizer ash pipe storehouse, the inner eddy flow that forms in the slag storehouse, thus can collect and store dried slag and economizer ash better, and the smooth operation of controlling air inlet of slag storehouse and exhaust better;
