Module (1)；
C, data processing：PLC control modules (1) handle cloth outputting moisture content, humiture, including data validation,
Humiture compensates automatically, the digitalization operation of cloth outputting moisture content nonlinear compensation, establishes the fitting of humiture and cloth outputting moisture content
Curve obtains the normality threshold of humiture using matched curve according to required cloth outputting moisture content；
D, exhaust blower speed regulation device controls：PLC control modules (1) are according to the high-accuracy temperature-humidity value after compensation, with normality threshold
It is compared, if high-accuracy temperature-humidity value sends out alarm not in the fluctuation range of normality threshold, by alarm module (26),
Signal is sent to host computer (29) by data transmission module (25) simultaneously；If high-accuracy temperature-humidity value is less than normality threshold,
Exhaust air rate then is reduced by controlling exhaust blower speed regulation device, if high-accuracy temperature-humidity value is higher than normality threshold, passes through the row of control
Fan speed adjuster increases exhaust air rate.
E, exhaust-gas treatment.
9. processing method according to claim 8, it is characterised in that：The humiture compensates automatically, is to use population
Optimization algorithm optimizes BP neural network, the compensation model of Temperature Humidity Sensor is established, using compensation model according to detection
Effective humiture gain of parameter automatically compensation after temperature and humidity value.
10. processing method according to claim 8, it is characterised in that：The step E is to include the following steps：
(1) high-temp waste gas being discharged into waste-heat recovery device (34) and carries out heat exchange, the hot wind after exchange returns in forming machine (3),
Low temperature waste gas, which then enters, carries out purified treatment in purifying box (41)；
(2) low temperature waste gas entered in purifying box (41) is introduced into cooling tube (42), by the cold water of spray tube (43)
Spray further decreases temperature, and low temperature waste gas is flowed out from fluid hole (44), by the filtering of filter screen (46) and adsorption layer (47)
And suction-operated, impurity and oil smoke are removed, then into electrostatic equipment (5), fume eliminating, foul smell are further removed, after purification
Gas up to standard be discharged into air, below standard gas is then secondary to enter purifying box (41) interior purified treatment；
(3) liquid in purifying box (41) carries out water-oil separating by oil water separator (6), and the oil isolated is collected storage,
Water is re-entered into spray tube (43) to use.
