Description
Technical field
The utility model relates to a kind of retracting device, particularly relates to a kind of papermaking dry portion waste heat recovery circulating device.
Background technology
As everyone knows, papermaking dry portion is link important in paper-making process, and Main Function sloughs the unnecessary moisture of page.Because wet web generally still has the moisture of 60%-70% after press section press, have to pass through drying section and again carry out thermal dehydration, the moisture making into paper is reduced to 4%-6%.So need a large amount of steam in the drying section stage, be also consume energy maximum position in whole paper mill.Through calculating, produce the about 1.5t water of the required evaporation of 1t paper, discharge these steam, ventiduct roadbed needed for drying section device is the fresh air of 50-100t, if can not the damp-heat air of high moisture content be discharged outside gas hood simultaneously, will certainly drying efficiency be affected, and injury is produced to the health of employee.
These steam is discharged outside gas hood by general ventilating system at present, and meanwhile, according to the needs of paper machine, some are fresh and air through heating is transported to drying section and carries out page heating.Find through test, the damp-heat air of discharging outside gas hood through ventilating system contains a large amount of height, thermal energy, its temperature reaches more than 90 DEG C, and these air with heat not only can cause a large amount of energy to run off after directly discharging, also can produce adverse influence to surrounding environment simultaneously.Therefore, these energy are carried out recycling, can effective economize energy.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of structure waste heat recovery circulating device in papermaking dry portion simple, easy to use, and this papermaking dry portion waste heat recovery circulating device can effective economize energy.
For solving the problems of the technologies described above, the utility model provides a kind of papermaking dry portion waste heat recovery circulating device, comprise heated roller, the sidewall of described heated roller is connected with the transfer tube communicated with described heated roller inside, described transfer tube is communicated with air collector by filter, the sidewall of described air collector is provided with multiple extension tube attached communicated with its inside.
Described filter comprises housing, is provided with filter element in described housing, and described enclosure interior is separated into the left steam chest and right steam chest that communicate by described filter element.
Described filter element comprises a screen pack and No. two screen packs, and a described screen pack and No. two filtration net covers are contained on axle and interval and arrange.
The inwall of described transfer tube, described filter and described air collector is provided with thermal insulation layer.
Compared with prior art, the beneficial effects of the utility model are: because the utility model can reclaim heat, store, and then be connected with other paper making equipment by extension tube attached, exchange heat is carried out again afterwards with other papermaking link, therefore, while the utility model is simple in structure, easy to use, effectively save the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: heated roller 2, transfer tube 4, bearing 5, filter 6, air collector 8, extension tube attached 10, filter element 62, left steam chest 64, right steam chest 66, screen pack 620, No. two screen packs 624, axle 68.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and embodiments, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, a kind of papermaking dry portion waste heat recovery circulating device, comprise the heated roller 2 for carrying out dry processing to l Water Paper, the sidewall of this heated roller 2 is connected with the transfer tube 4 communicated with heated roller inside, this transfer tube 4 is connected with the sidewall of heated roller 2 by suit bearing 5 thereon, transfer tube 4 is communicated with air collector 8 by filter 6 simultaneously, the sidewall of air collector 8 is provided with multiple extension tube attached 10 communicated with its inside.Based on said structure design, the utility model can reclaim heat, store, and then is connected with other paper making equipment by extension tube attached 10, carries out exchange heat more afterwards, therefore, effectively make use of the energy.
Concrete, filter 6 comprises housing 60, is provided with filter element 62 in this housing 60, the left steam chest 64 that housing 60 interior separation becomes to communicate by filter element 62 and right steam chest 66.In addition filter element 62 comprises a screen pack 620 and No. two screen packs 624, and this screen pack 620 and No. two screen packs 624 are sleeved on axle 68 and interval and arrange, and the filter 6 of this structure has the advantage of good filtration effect.The inwall of transfer tube 4, filter 6 and air collector 8 is provided with thermal insulation layer, effectively can prevent heat loss like this.
