Abstract
The utility model discloses a tube bank dryer secondary steam recycling device, which belongs to the starch production matching device technical field. The recycling device comprises a dust-removing pot, a draft fan, a circulation pump and a water tank; wherein, a water outlet is arranged under the water tank. The device is characterized in that a water spraying nozzle is arranged at the top part of the dust-removing pot; the water spraying nozzle is connected with the circulation pump through a pipeline; the circulation pump is connected with the water tank through the pipeline; a drain pipe communicated with the water tank is arranged at the bottom of the dust-removing pot; a steam inlet and a steam outlet are arranged at the upper part of the dust-removing pot; the steam inlet is connected with an exhaust hole of the tube bank dryer; and the steam outlet is connected with the draft fan through the pipeline. The device has the beneficial effects that the environment pollution problem of the secondary steam for the tube bank dryer is solved; the waste heat of the secondary steam can be effectively utilized, so as to achieve the purpose of recycling utilization, saving energy and lowering energy consumption.
Description
Technical field the utility model belongs to Starch Production support equipment technical field, relates to a kind of Starch Production industry pipe bundle drier secondary steam retrieving arrangement.
The background technology pipe bundle drier is the equipment that the starch industry generally adopts, and is mainly used to dry maize peel and maize germ.Maize peel and plumule water content are higher, become secondary steam after heating, are extracted out by blower fan through venting port.The secondary steam temperature also contains the small part fines simultaneously at 75 ℃.Though because of this part steam contains certain heat energy, temperature is on the low side a little again, therefore, present domestic starch producer all directly discharges this part steam, has caused following influence thus: the one, and the secondary steam of discharging causes visual pollution; The 2nd, the fines in the steam is distributed in the air and produces dust and influence environment; The 3rd, waste heat does not reclaim and causes energy serious waste.
Utility model content the purpose of this utility model is to solve the technical problem that there is contaminate environment in prior art, wastes energy, and provides a kind of pipe bundle drier secondary steam retrieving arrangement, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model pipe bundle drier secondary steam retrieving arrangement is realized that by following technical scheme it comprises dedusting tank, induced draft fan, recycle pump and water tank, is provided with water outlet below the water tank; The top of dedusting tank is provided with water injection nozzle, and water injection nozzle is connected with recycle pump by pipeline, and recycle pump is connected with water tank by pipeline, and the bottom of dedusting tank is provided with the water shoot that is communicated with water tank; The top of dedusting tank is provided with steam inlet and vapour outlet, and steam inlet links to each other with the pipe bundle drier venting port, and vapour outlet links to each other with induced draft fan by pipeline.
The beneficial effects of the utility model are to have solved the problem of environmental pollution of pipe bundle drier secondary steam; Effectively utilize the waste heat of secondary steam, reached recycle, energy saving purposes.
Appended drawings is the utility model structural representation.
Embodiment with reference to the accompanying drawings, it comprises dedusting tank 5, induced draft fan 7, recycle pump 2 and water tank 8 the utility model, is provided with water outlet 1 below the water tank 8; The top of dedusting tank 5 is provided with water injection nozzle 4, and water injection nozzle 4 is connected with recycle pump 2 by pipeline, and recycle pump 2 is connected with water tank 8 by pipeline, and the bottom of dedusting tank 5 is provided with the water shoot that is communicated with water tank 8; The top of dedusting tank 5 is provided with steam inlet 3 and vapour outlet 6, and steam inlet 3 links to each other with the pipe bundle drier venting port, and vapour outlet 6 links to each other with induced draft fan by pipeline.
Pipe bundle drier carries after exhaust blower discharges secondary steam, enters dedusting tank 5 by steam inlet 3, simultaneously the water injection nozzle 4 of tank deck downwards water spray form the dedusting moisture films, water is discharged by the water shoot of dedusting tank 5 bottoms; Dedusting tank 5 waters source is the steam condensate that pipe bundle drier is discharged, and temperature is at 96-100 ℃, and its effect one is the fines that absorbs in the secondary steam, the 2nd, and its temperature is higher to guarantee that vapor temperature can not reduce too much.Dedusting water is discharged the laggard water tank 8 of going into from water shoot, is recycled pump 2 suction water injection nozzles 4 again, so recycles.When higher or temperature is low when fines content in the dedusting water, discharge by water port 1, inject the new water of equivalent from the water filling port at dedusting tank 5 tops, from vapour outlet 6, under the effect of induced draft fan 7, enter the equipment that needs with vapour by pipeline through the secondary steam after the dedusting.
The utility model has solved steam and has directly effluxed the environmental influence that causes, and compact construction, easy to operate, less investment, reduce enterprise energy consumption, solved secondary steam and directly efflux the environmental influence that causes, therefore in the Starch Production industry, had great application value.
