Description
Technical field
This utility model relates to paper making equipment field, especially relates to the residual neat recovering system of a kind of paper making equipment.
Background technology
At present, the hot blast gas hood that present stage the most just installs is generally divided into closed gas hood, type of respiration gas hood and
High speed hot blast gas hood.Closed gas hood is generally used for corrugated paper machine, culture paper etc., but the power consumption of closed air hood is higher,
The utilization rate of the thermal efficiency is low；Type of respiration gas hood is generally used for cylinder mould machine, is primarily adapted for use in low speed paper machine.High speed hot blast gas hood
Being to use contact drying and convective drying principle, high temperature and high speed hot blast makes hot blast produce convection heat transfer' heat-transfer by convection quickly, same intermittent fever to paper
Wind vertically blows on paper, and the air film on interface is destroyed or lower thickness, thus heat transfer and mass tranfer coefficient are greatly increased,
Enhancing evaporation, paper machine yield and cylinder dried efficiency can be greatly improved, steam consumption is low.
Summary of the invention
For the deficiencies in the prior art, this utility model provides the paper making equipment with waste heat recovery, can not only accelerate volume
The manufacturing of paper, and reduce the loss of the energy, more energy-conserving and environment-protective, for reaching above-mentioned purpose, adopt the following technical scheme that
A kind of residual neat recovering system of paper making equipment, including: drying cylinder and gas hood, heat exchanger, described drying cylinder top is provided with
Gas hood, the blast pipe of gas hood is connected to aerator, and the exhaustor of gas hood connects and heat exchanger, and the gas outlet of heat exchanger is connected to drum
The air inlet of blower fan.
Further, the described gas hood left and right sides is equipped with blast pipe, by former and later two gas hoods by drying cylinder top half
Cover.
Further, many little airducts of arch arrangement, the exit of little airduct and drying cylinder it are provided with in described gas hood
The paper on surface is relative, and the exit of little airduct is connected with the blast pipe of gas hood.
Further, the surrounding of described gas hood is provided with heat-preservation cotton, for hot blast gas hood being realized preferably insulation,
Prevent the waste of the energy；Described heat exchanger is connected to air-introduced machine.
Further, it is provided with the temperature sensor for measuring temperature, gas hood and blast pipe inside described gas hood to connect
Place is provided with the control valve for controlling air quantity, the most intelligently controls the running of paper making equipment, the consumption of regulation energy and
Circulation.
The beneficial effects of the utility model are:
When gas hood carries out heating, drying to drying cylinder, residual neat recovering system utilizes heat exchanger to reclaim waste gas, by two
Secondary hot blast is circulated utilization in discharging into gas hood, thus the loss of energy needed for reducing paper making equipment, greatly reduce coil paper
Manufacturing cost；This utility model simple in construction, waste gas repeatedly utilize thus improve the utilization ratio of heat energy, it is provided that the life of product
Yield and quality.
Accompanying drawing illustrates:
Accompanying drawing 1 is axonometric chart of the present utility model；
Accompanying drawing 2 is front view of the present utility model.
Detailed description of the invention:
In order to make juror can the purpose of this utility model, feature and function be further understood that, hereby lift preferably
Embodiment also coordinates graphic detailed description as follows:
Referring to shown in Fig. 1 ~ 2, be the structural representation of the preferred embodiment for this utility model, this utility model is one
Plant the residual neat recovering system of paper making equipment, including: drying cylinder 1 and gas hood 2, heat exchanger 3, described drying cylinder 1 top is provided with gas hood 2,
The blast pipe 21 of gas hood 2 is connected to aerator 4, and the exhaustor 22 of gas hood 2 connects and heat exchanger 3, and the gas outlet 31 of heat exchanger 3 is even
It is connected to the air inlet 41 of aerator 4.Described heat exchanger 3 is connected to air-introduced machine 6.
Such scheme, gas hood 2 left and right sides is equipped with blast pipe 21, former and later two gas hoods 2 drying cylinder 1 top half covered
Lid.The paper on many little airducts 23 of arch arrangement, the exit of little airduct 23 and drying cylinder 1 surface it is provided with in described gas hood 2
Opening relatively, the exit of little airduct 23 is connected with the blast pipe 21 of gas hood 2, and the hot blast being more dried is passed through little wind by blast pipe 21
Pipe 23 is discharged, and for drying paper, the surrounding of described gas hood 2 is provided with heat-preservation cotton 5, in realizing hot blast gas hood more
Good insulation, prevents the waste of the energy.
Such scheme, gas hood 2 is internal is provided with the temperature sensor 7 for measuring temperature, and temperature sensor 7 can be examined effectively
Measure the temperature within gas hood 2, it is to avoid too high or too low for temperature, cause the Quality Down of coil paper, gas hood 2 and blast pipe 21 to connect
Place is provided with the control valve 8 for controlling air quantity, the most intelligently controls the running of paper making equipment, the consumption of regulation energy and
Circulation.
During enforcement, first hot blast enters gas hood 2 from blast pipe 21, by the outlet of the little airduct 23 of gas hood 2 by aerator 4
