The structural representation of the gas fume conveying system of Fig. 1 prior art, with reference to shown in Figure 1, the gas fume conveying system of prior art comprises following components successively: flue gas input channel, cooling air input channel, mixing chamber, smoke conveying duct, dust pelletizing system, air-introduced machine, flue gas blending bin, drying air fan etc.
The utility model content
Technical problem to be solved in the utility model provides a kind of fiber drying flue gas attemperating unit, can effectively regulate flue-gas temperature, and can reduce the energy consumption in fiber drying in the Fibreboard Production, the course of conveying, and then reduces production costs.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of fiber drying flue gas attemperating unit, comprise: the flue gas input channel, the cooling air input channel, mixing chamber, smoke conveying duct, dust pelletizing system, air-introduced machine, the flue gas blending bin, drying air fan, flue gas input channel and cooling air input channel are located at a side of mixing chamber side by side, the opposite side of mixing chamber is connected to dust pelletizing system by smoke conveying duct, air-introduced machine is located between dust pelletizing system and the flue gas blending bin, drying air fan is located at flue gas blending bin opposite side, between dust pelletizing system and air-introduced machine, be equipped with flue between air-introduced machine and the flue gas blending bin, it is characterized in that being provided with air door at the position relative, flue gas blending bin side with the dry flue gas fans entrance.
Described air door is made up of grid, rocking bar, adjusting YE, and grid is installed in the framework two side of air door, is connected on the air door YE by rocking bar, between rocking bar and the rocking bar, all be connected by oscillating bearing between rocking bar and the grid.When flue-gas temperature changes, temperature sensor in the flue passes to PLC (programmable controller) with the signal of variations in temperature, PLC feeds back to YE after signal is handled then, the corresponding rotating band of making YE shakes the bar motion, rocking bar drives the grid swing, grid can collective open and close under the effect of rocking bar, and the degree that opens and closes is subjected to the interior temperature program instruction of PLC to make corresponding adjusting, enter the amount of the air of system with control, when flue-gas temperature is very high, the air door grid is opened greatly, and when flue-gas temperature was high slightly, the air door grid was opened a little, when flue-gas temperature is moderate, the air door grid is closed, and the aperture of air door grid size just forms an automatic control system with flue-gas temperature like this, and the information exchange between PLC realization and man-machine interface
The utility model has following positive effect: the utility model is provided with the adjustable air door of aperture at the position relative with the dry flue gas fans entrance, flue gas blending bin side, can be according to the height of flue-gas temperature, the amount of the Cryogenic air that control is introduced, generally speaking can introduce than conventional art more the air of the low temperature of volume mix in the flue gas blending bin with high-temperature flue gas, flue gas blower fan outlet temperature is controlled in 300-360 ℃, flue gas pressures rises to 7-12mbar, the drying air fan inlet temperature is reduced to safe below 175 ℃, the pressure oscillation of flue gas be improved significantly.Therefore can reach accurate control flue-gas temperature on the one hand, reduce the purpose of flue-gas temperature, obtain satisfactory fiber moisture.On the other hand, introduce fresh Cryogenic air after, increased the total amount of flue gas, improved the pressure of dry flue gas behind the drying blower fan.Equipment simply is easy to realize, and operation is convenient, has reduced the cost of operation.
