Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of waste heat recovery plant for drying box is provided, the Waste Heat Recovery of discharging in drying box can be utilized, the gas recovery higher than normal temperature to temperature carries out heat temperature raising again, shorten time and the energy consumption of heat temperature raising, accomplish environmental protection and energy saving.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of waste heat recovery plant for drying box, comprise filter, heat exchanger, pressure fan and electric heater, the air inlet of described filter is communicated with the exhaust outlet of drying box, described heat exchanger is provided with the first air inlet, second air inlet, first row gas port and second exhaust port, described first air inlet is communicated with described pressure fan, described second air inlet is communicated with described filter, the first row gas port of described heat exchanger is communicated with described electric heater, the exhaust outlet of described electric heater is communicated with the air inlet of described drying box, described second exhaust port discharging waste gas.
In technique scheme, be provided with electric heating tube in described electric heater, the two ends of described electric heating tube are fixed in the shell of described electric heater.
In technique scheme, described first air inlet is communicated with first row gas port, and described second air inlet is communicated with second exhaust port.
In technique scheme, described second exhaust port is communicated with adsorption tower.
In technique scheme, described pressure fan is turbofan.
In technique scheme, the air inlet of described pressure fan is provided with dedusting filter screen.
In technique scheme, the shell of described heat exchanger is heat-insulation layer.
The beneficial effects of the utility model are: overall structure is simply practical, just heat exchange is carried out by after the filtration of waste heat gas being carried out to filter, avoid in the process of heat exchange, impurity in waste gas causes pipeline obstruction in the duct because temperature reduces thus falls to sink, outside air to be sent into the filters dust in air before heat exchanger through dedusting filter screen through pressure fan, ensure that applying material surface can not adhering dust, ensure the quality of applying material.The Waste Heat Recovery of discharging in drying box can be utilized, the gas recovery higher than normal temperature to temperature carries out heat temperature raising again, shortens time and the energy consumption of heat temperature raising, accomplishes environmental protection and energy saving.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of waste heat recovery plant for drying box 11, comprise filter 1, heat exchanger 2, pressure fan 3 and electric heater 4, the air inlet of described filter 1 is communicated with the exhaust outlet of drying box 11, described heat exchanger 2 is provided with the first air inlet 6, second air inlet 7, first row gas port 8 and second exhaust port 9, described first air inlet 6 is communicated with described pressure fan 3, described second air inlet 7 is communicated with described filter 1, the first row gas port 8 of described heat exchanger 2 is communicated with described electric heater 4, the exhaust outlet of described electric heater 4 is communicated with the air inlet of described drying box 11, described second exhaust port 9 discharging waste gas.
Wherein, be provided with electric heating tube 5 in described electric heater 4, the two ends of described electric heating tube 5 are fixed in the shell of described electric heater 4.The two ends of electric heating tube 5 are wired to power supply.The shell of electric heater 4 is lagging casing, ensures the stability of heating-up temperature.Electric heating tube 5 generally adopts W type electric heating tube 5, adds heat.
Wherein, described first air inlet 6 is communicated with first row gas port 8, and described second air inlet 7 is communicated with second exhaust port 9.The waste gas of discharging from drying box 11 enters into heat exchanger 2 from the second air inlet 7 and carries out heat exchange after the filtration of filter 1, discharges enter adsorption tower after completing heat exchange from second exhaust port 9.Outside air is entered into heat exchanger 2 from the first air inlet 6 and carries out heat exchange by pressure fan 3, escapes and enter electric heater 4 and carries out heat temperature raising, reach the temperature required for drying after completing heat exchange from first row gas port 8.
