Abstract
The utility model relates to a heat recovery system on the papermaking production line, belonging to the technical field of the heat recovery system. The heat recovery system comprises a heat exchanger, wherein the upper end and the lower end of the heat exchanger are respectively provided with an air outlet and an air inlet which are communicated; an air outlet pipe is connected on the air outlet by a pipeline; a fresh air port and a hot air port which are communicated are respectively arranged at the middle part of the heat exchanger; and an air cover is connected on the hot air port by a pipeline. The heat recovery system has the advantages that the structure is simple and the design is reasonable; a path of heat from a drying part of a paper machine enters the heat exchanger, aluminium pipes of the heat exchanger are heated, and the waste heat is discharged from the air outlet; another path of fresh air enters the fresh air port of the heat exchanger, enters the air cover after being heated by the aluminium pipes of the heat exchanger and is used for other heating; the heat and the heat steam generated on the papermaking production line are reasonably utilized, so that the energy-saving and emission-reducing purposes are achieved and the production cost is reduced.
Description
Technical field
The utility model belongs to the heat recovery system technical field, is specifically related to the heat recovery system on the paper production line.
Background technology
(particularly paper machine oven dry portion) can produce great amount of heat, vapours etc. in the paper-making process.At present also utilize some heat recovery systems in the actual production, but this type of heat recovery system complex structure, acquisition cost are high, are not suitable for utilization and extention in small business.And in most small business, generally do not recycle these heats, vapours etc., caused the waste of resource.
The utility model content
To the problem that prior art exists, the purpose of the utility model is to design the technical scheme that the heat recovery system on a kind of paper production line is provided.
Heat recovery system on the described paper production line; It is characterized in that comprising heat exchanger; Described heat exchanger is respectively equipped with exhaust outlet and the air inlet that communicates in two ends up and down; Described exhaust outlet upper pipeline connects exhaust duct, and described heat exchanger middle part is respectively equipped with fresh wind port and the hot-air mouth that communicates, and described hot-air mouth upper pipeline connects gas hood.
Heat recovery system on the described paper production line is characterized in that being provided with between described exhaust outlet and the exhaust duct blower fan II.
Heat recovery system on the described paper production line is characterized in that being provided with between described hot-air mouth and the gas hood blower fan I.
Heat recovery system on the above-mentioned paper production line, simple in structure, reasonable in design, one road heat from the collection of paper machine oven dry portion gets into heat exchanger from air inlet, makes the aluminum pipe heating of heat exchanger, and discharges used heat from exhaust outlet; Another road fresh air gets into the fresh wind port of heat exchanger, and the aluminum pipe heating through heat exchanger gets in the gas hood, is used for other heating.Heat, vapours that the utility model rationally utilizes paper production line to produce have been accomplished energy-saving and emission-reduction, have reduced production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-blower fan I; The 2-gas hood; The 3-fresh wind port; The 4-heat exchanger; The 5-exhaust outlet; The 6-exhaust duct; 7-blower fan II; The 8-hot-air mouth; The 9-air inlet.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure; Heat recovery system on the paper production line; Comprise heat exchanger 4 (by buying on the market), the two ends up and down of heat exchanger 4 are respectively equipped with the exhaust outlet 5 and air inlet 9 that communicates, and the middle part of heat exchanger 4 is respectively equipped with the fresh wind port 3 and hot-air mouth 8 that communicates.Exhaust outlet 5 upper pipelines connect exhaust duct 6, and between exhaust outlet 5 and exhaust duct 6, blower fan II7 are set, and blower fan II7 is used for exhausting.Hot-air mouth 8 upper pipelines connect gas hood 2, and between hot-air mouth 8 and gas hood 2, blower fan I 1 are set, and blower fan I 1 is used for exhausting.
Two interactional pipelines are arranged in the utility model, and one the tunnel comprises air inlet 9, exhaust outlet 5 and the exhaust duct 6 of heat exchanger 4.This road makes the aluminum pipe of the waste heat reheat heat exchanger 4 of collecting in the paper machine oven dry portion in the paper production line through the exhausting of blower fan II, discharges from exhaust duct 6 again.Another road comprises the hot-air mouth 8 and the gas hood 2 of fresh wind port 3, heat exchanger 4.This road makes fresh air get into from fresh wind port 3 through the exhausting of blower fan I1, through the heating of heat exchanger 4, is transported in the gas hood 2 again, is used for other effect.
Shown in the above and the figure only is the preferred implementation of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be regarded as belonging to the protection domain of the utility model.
