Hot air tentering setting machine and exhaust air rate control method thereof

Abstract

The invention provides a hot air tentering setting machine and an exhaust air rate control method thereof. The hot air tentering setting machine comprises a tentering setting cloth feeding device, a drying setting device, a tentering setting cloth discharging device, an oxygen content analyzer, a flue gas content laser detection system, an air return device and a control system which are connected in sequence, The humidity of a front-section drying oven of the setting machine is indirectly detected through the oxygen content analyzer (the humidity of the front section of the drying oven is controlled within a reasonable range), so that the energy consumption value can be effectively reduced. The flue gas content laser on-line detection system is used at the tail part of the rear half section of the drying oven of the setting machine, and the speed of an exhaust fan is automatically adjusted by controlling the flue gas concentration in the drying oven, so that the purposes of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of setting machines, in particular to a hot air stenter setting machine and a method for controlling the exhaust air volume thereof. Background technique [0002] Heat setting is an indispensable production process in the textile printing and dyeing industry, and the hot air stenter setting machine is the most widely used machine type. Although my country's printing and dyeing industry has reached a certain level in terms of scale, compared with developed countries, there are still problems of "heavy pollution, high energy consumption, and low production capacity". The heat setting process accounts for more than half of the energy consumption of the entire printing and dyeing process, so the level of heat setting energy consumption has an important impact on the overall energy consumption of the printing and dyeing industry. In the actual production process of heat setting, manufacturers pay attention to the heat set...

Problems solved by technology

However, when the ordinary humidity detector is set at a temperature of about 200 ° C, the temperature during preparation cannot meet the working requirements of the humidity detector, and the price of imported equipment is relatively high.
