A kind of lear outer air exhaust waste heat recycling import air duct wind pressure controller
Technical field
The utility model is related to air exhaust waste heat recycling import air duct wind pressure controllers outside a kind of lear.
Background technology
At present in Improving Glass Manufacturing Processes, the outer air draft of all lears is all to be directly discharged into air, causes the energy unrestrained
Take, main cause is that wind pressure control is stringent in lear kiln, glass production quality otherwise can be seriously affected, so that waste heat
It can not utilize.
Utility model content
The technical problems to be solved in the utility model is in view of the defects existing in the prior art, to design a kind of glass annealing
Kiln outer air exhaust waste heat recycling import air duct wind pressure controller, the effectively wind at control and the outer wind exhausting outlet of adjusting lear
Pressure, it not only can guarantee a large amount of recycling of waste heat, but also ensure the quality of glass production.
The technical solution of the utility model is, described to recycle import air duct wind pressure control for the outer air exhaust waste heat of lear
Device processed be the heat source of the multiple outer air drafts of glass annealing kiln is pooled to air duct main pipe by air duct branch pipe, then by air duct main pipe concentrate into
Enter the outer air exhaust waste heat recover ontology of glass annealing kiln, branch pipe and air duct main pipe install wind pressure controller respectively in air duct, effectively control
Wind pressure at system and the outer wind exhausting outlet of adjusting lear, it not only can guarantee a large amount of recycling of waste heat, but also ensure glass production
Quality, substantially reduce enterprise operation cost.
Further explanation is made to the utility model below.
It is described for lear outer air exhaust waste heat recycling import air duct wind pressure controller referring to Fig. 1, including into one's intention as revealed in what one says
The wind pressure controller II 4 on wind pressure controller I 2, import air duct branch pipe II 3 on road branch pipe I 1, import air duct mother's branch pipe 5 are remaining
Heat regenerator import main pipe wind pressure controller III 6, its main feature is that, each import air duct branch pipe and the control of import air duct main pipe wind pressure
Wind pressure measuring point PT is installed respectively before deviceA、PTB、PTC, first can according to air exhaust waste heat recover ontology outside lear and into,
Resistance to flow output variable frequency adjustment air-introduced machine electric current controls PT before import main pipe wind pressure controller III 6CWind pressure, further according to import main pipe
PT before wind pressure controller III 6CWind pressure controls PT before import air duct branch pipe I 1, import air duct branch pipe II 3A、PTBWind pressure, finally
According to PT before import air duct branch pipe I 1, import air duct branch pipe II 3A、PTBWind pressure adjust air-introduced machine aperture, according to import air duct
PT before branch pipe I 1, import air duct branch pipe II 3A、PTBWind pressure controlled by variable frequency adjustment air-introduced machine electric current, be finally reached stringent
The wind pressure for controlling the outer air draft air outlet of lear, meets process of glass.
A kind of lear of the utility model outer air exhaust waste heat recycling import air duct wind pressure controller, it is necessary to strictly press
Control logic requires to carry out.
The utility model has the beneficial effects that:A kind of lear of the utility model outer air exhaust waste heat recycling import air duct
Wind pressure at wind pressure controller, effectively control and the outer wind exhausting outlet of adjusting lear, it both can guarantee that a large amount of of waste heat returned
It receives, and ensures the quality of glass production.

Specific implementation mode
As shown in Figure 1 to Figure 2, described for a kind of lear outer air exhaust waste heat recycling import air duct wind pressure control
Device, it include import air duct branch pipe I 1, wind pressure controller I 2, import air duct branch pipe II 3, wind pressure controller II 4, import air duct
Main pipe 5, wind pressure controller III 6, waste-heat recoverer ontology 7, air-introduced machine 8, chimney 9 etc., the outer air exhaust waste heat recover of annealing kiln are logical
It crosses wind pressure adjusting device and collects the outer air draft heat source of dispersion annealing kiln, realize a large amount of waste heat recoveries, pass through the change frequency modulation of air-introduced machine 8
Wind pressure in import air duct main pipe 5 is saved, while according to wind pressure in import air duct main pipe 5, adjusting wind pressure controller I 2, wind pressure controller
II 4, reach the wind pressure for effectively adjusting import air duct branch pipe I 1, import air duct branch pipe II 2, ensures the outer wind exhausting outlet wind pressure of annealing kiln
Stablize, it is stringent to control the outer wind exhausting outlet wind pressure of annealing kiln, glass production quality is not influenced.
Simultaneously in 5 design wind pressure controller III 6 of import air duct main pipe and bypass blow valve, as waste-heat recoverer ontology 7 needs
Wind pressure controller III 6 can be closed by overhauling, and opened bypass blow valve, do not influenced glass production.
