Description
Technical field
The present invention relates to heat recovery technology fields, and in particular to a kind of printing machine waste heat recovery of circulatory system.
Background technique
Printing be the original copys such as text, picture, photo are made through processes such as plate-making, Shi Mo, pressurizations printing ink transfer to paper,
On the material surfaces such as fabric, leather.Printing machine is exactly the machine of printing word and image.Different printing technologies was being printed
Drying system is needed to carry out the drying of the substances such as ink to stock in journey, to achieve the effect that beauty.In printing drying course
In, printing machine heats up to cold air by heating device, and hot gas is transported in baking oven by blower and is dried to stock, then is passed through
Cross exhaust blower exhaust gas is expelled to outside baking oven, between constantly recycle.In the process, the amount of heat in baking oven is arranged with air draft
Out, a large amount of heat-energy losses are caused.
Summary of the invention
The object of the present invention is to provide a kind of printing machine waste heat recovery of circulatory system, with solve in the prior art printing machine because
Generate a large amount of waste heats do not utilize and caused by energy waste problem.
To achieve the above object, The technical solution adopted by the invention is as follows:
Printing machine waste heat recovery of circulatory system, including rack, rack are equipped with printing drying box, and printing drying box is equipped with
First air inlet and the first gas outlet, rack are equipped with the heat exchanger tube to circulate for waste hot gas, are equipped with rabbling mechanism in heat exchanger tube, change
Hot cylinder is equipped with the second air inlet and the second gas outlet, and the first gas outlet is connected to the second air inlet, and the second gas outlet is communicated with
Waste gas treatment mechanism；It is socketed with sleeve on heat exchanger tube, forms the cavity led to for cold airflow between sleeve and heat exchanger tube, is set on sleeve
There are third air inlet and third gas outlet, third air inlet is communicated with blower, and third gas outlet is connected to the first air inlet, third
Having heaters is connected between gas outlet and the first air inlet.
Compared with prior art, the principle of the present invention and the utility model has the advantages that
1, heat exchanger tube and sleeve are set, and the waste hot gas being discharged from the first gas outlet of printing drying box will go into heat exchanger tube
In, and blower will be into cavity for cold air, since sleeve is socketed on heat exchanger tube, cavity is coated on heat exchange drum outer wall, waste heat
Gas and cold air will carry out heat exchange by flowing, i.e. waste hot gas transfers heat to cold air, heats to cold air, makes chill temperature
When spending and increase, then passing through heater to cold gas to drying temperature, consumed energy will be reduced, the remaining heat recovery cycle of realization
It utilizes, has achieved the effect that energy saving；In addition, waste hot gas is not contacted with cold air in heat transfer process, can avoid in waste hot gas
Impurity pollutes cold air and influences the dry effect of subsequent printing.
2, rabbling mechanism is set, using being stirred in rabbling mechanism heat exchanging cylinder, due to giving up for heat exchanger tube middle section
Hot gas is farthest apart from cavity, most slow with cold air heat exchange, and stirs the steady flow that can break waste hot gas, makes whole give up
Hot gas rapidly can carry out heat exchange with cold air, improve rate of heat exchange, achieve the effect that maximum waste heat recycling.
3, waste gas treatment mechanism is set, due to usually containing ethyl acetate, ethyl acetate, first in the waste hot gas after drying
The inflammable and explosive perishable gas such as benzene, dimethylbenzene will cause great harm environment and human body if direct emission, using useless
Gas disposal mechanism handles the waste hot gas that the second gas outlet is discharged from heat exchanger tube, achievees the effect that impurity and purification, improves
Environmental-friendly degree.
Further, the sleeve lining is equipped with multiple for limiting the baffler of cold air flow.
Baffler is set, the flowing of cold air in the cavities can be limited, due to the blocking of group partition, increase cold air in cavity
In flow path, to extend cold air residence time in the cavities, and then be able to carry out cold air and waste hot gas sufficiently
Heat exchange, rate of heat exchange is improved, to achieve the effect that the recycling of maximum waste heat.
Further, the waste gas treatment mechanism includes the reaction container equipped with organic solvent and adsorption box equipped with adsorbent,
The first conduit is communicated between second gas outlet and reaction container, the first conduit stretches in organic solvent, reaction container and adsorption box
Between be communicated with the second conduit, the second conduit is located at the top of organic solvent liquid level.
The waste hot gas being discharged from the second gas outlet enters in reaction container, since the first conduit stretches in organic solvent,
Therefore waste hot gas will from the first conduit discharge after fully with organic solvent exposure, and due in waste hot gas contain ethyl acetate,
The inflammable and explosive perishable gas such as ethyl acetate, toluene, dimethylbenzene, and these gases are organic matter, therefore pass through phase patibhaga-nimitta
Molten principle can dissolve in organic solvent, and air is insoluble with organic solvent, will be entered in adsorption box by the second conduit, lead to
Adsorbent effect is crossed, the gases such as impurity and possible remaining ethyl acetate, ethyl acetate, toluene, dimethylbenzene are further removed；It is logical
The double action of dissolution and absorption is crossed, the processing capacity of impurity in waste hot gas is improved, to effectively clean, reduces waste hot gas to ring
The harm in border and human body.
Further, the rabbling mechanism includes the shaft being rotatably connected in heat exchanger tube, and shaft is equipped with stirring blade, machine
Frame is equipped with the cabinet being connected to adsorption box, and the turbine coaxially connected with shaft is rotatably connected in cabinet, and cabinet is equipped with row
Stomata.
Then waste hot gas after adsorption box cleans is discharged, waste hot gas exists in the process through entering in cabinet from gas vent
Lasting air-flow is formed in cabinet, which will be used as drive force turbine rotation, and turbine will drive shaft rotation, and shaft will
Stirring blade rotation is driven, is stirred in heat exchanging cylinder.Cabinet is set, the waste hot gas of discharge is utilized, its conduct is made
Drive force stirring, no setting is required additional power source have achieved the effect that energy saving；And the waste hot gas is through exhaust gas
Processing mechanism is purified, eliminates the inflammable and explosive susceptibility-to-corrosion such as impurity and ethyl acetate, ethyl acetate, toluene, dimethylbenzene
Gas is carried out as driving force in use, will not damage to equipment；Further, since stirring blade has certain volume
And area, therefore the flowing of waste hot gas generates barrier effect in meeting heat exchanging cylinder in whipping process, makes waste hot gas in heat exchanger tube
Interior residence time increases, so that waste hot gas be enable fully to carry out heat exchange with cold air, to improve rate of heat exchange, i.e., will
The heat of waste hot gas farthest passes to cold air.
Further, curved channel is equipped in the adsorption box.
Channel is set, after so that waste hot gas is entered adsorption box, is entered in channel, it is not direct to be contacted with adsorbent, it avoids inhaling
Impurity in attached dose causes secondary pollution to waste hot gas；And it is bent the channel of setting, row of the waste hot gas in adsorption box can be increased
Journey can be stopped fully with adsorbent, to enable adsorbent more thoroughly by nocuousness remaining in waste hot gas
Gas is removed.
Further, insulating layer is coated on the sleeve.
Insulating layer is set, and heat is lost in reduction heat exchanging process, farthest improves the recovery efficiency of waste heat, reaches
To the effect to economize on resources.
