Description
Technical Field
The invention relates to the field of setting machines, in particular to a hot air tentering setting machine and an air exhaust amount control method thereof.
Background
The heat setting is an essential production process in the textile printing and dyeing industry, and the hot air tentering setting machine is a machine type with more applications. Although the printing and dyeing industry in China reaches a certain level on scale, compared with developed countries, the printing and dyeing industry still has the problems of heavy pollution, high energy consumption and low productivity. The heat setting process accounts for more than half of the energy consumption of the whole printing and dyeing process, so the heat setting energy consumption has important influence on the whole energy consumption of the printing and dyeing industry. In the actual production process of heat setting, manufacturers pay attention to the heat setting effect of the fabric on one hand and pay attention to the output energy consumption condition of the product on the other hand. From the heat balance analysis of a general hot air tentering setting machine, the effective heat energy consumed by the fabric in the setting process accounts for 28.25% of the total heat, the exhaust loss heat accounts for 59.76% of the total heat, and the equipment and wall heat dissipation accounts for 9.72% of the total heat. Therefore, the important point for energy saving of the hot air tenter setting machine is to control the exhaust heat loss.
The hot air tentering setting machine continuously discharges partial hot air from the drying room of the equipment in the running process of drying the fabric, so as to take away a large amount of water vapor and other volatile gases (such as some dyes, auxiliary agents or sublimed substances of resin and the like) generated in the drying and setting process of the fabric, and continuously replenish fresh hot air. In the process, if the air quantity discharged by the equipment is too small, the humidity of the air in the drying room of the equipment is increased, and finally, the normal operation of the equipment cannot be maintained; and too much air discharge amount consumes too much energy, which is not economical. When the fabric is shaped at the back half section of the shaping machine, as the drying oven basically does not contain water vapor, mainly volatilized oil smoke, more heat energy can be utilized; in the process of the second half section, only the overlarge smoke, the pollution to equipment and the escaping of the setting machine are needed to be avoided. Therefore, it is important to keep the exhaust gas discharge rate at the optimum value during the operation of the setting machine equipment, and of course, it is important to maintain the normal operation of the equipment. Most of the exhaust fans of the setting machines at present run at full speed according to the rated exhaust speed of the equipment to discharge exhaust gas, but actually, the exhaust gas speed of the equipment is reduced a little under most conditions, the fabric can also obtain the same or even better drying and setting effects, and a large amount of kinetic energy and heat energy can be saved. Under the condition that the temperature of the ordinary humidity detector reaches about 200 ℃, the temperature during preparation cannot meet the working requirement of the humidity detector, and the price of imported equipment is high. Therefore, I introduce an oxygen content analyzer, indirectly represent the content of water vapor (namely humidity) in the oven by detecting the change of the oxygen content in the front half section of the oven, then find out the allowable safe moisture content range in the oven through a large number of seed distribution tests, introduce an oil smoke detector at the tail part of the oven, find out the proper smoke discharge amount, finally regulate and control the air exhaust rate of the front and rear exhaust fans of the oven through a PID algorithm (a PID controller controlled according to the proportion (P), the integral (I) and the differential (D) is also called as a PID regulator) conversion program, and maintain a relatively energy-saving operation mode.
Therefore, it is urgently needed to provide a hot air tentering setting machine which can effectively save energy consumption value.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following disclosure provides many different embodiments or examples for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.
As shown in fig. 1, the temperature change of the wet fabric during heat setting can be divided into three distinct stages.
The first stage, the preheating stage, is when the temperature of the fabric is low and the temperature of the fabric surface cannot be maintained stably to allow the moisture on the surface to evaporate uniformly, so that the temperature of the fabric needs to be raised, in fig. 1, the temperature of the fabric is raised from the initial ambient temperature and reaches the equilibrium temperature relatively quickly, and although a certain amount of moisture is evaporated, most of the energy obtained by the fabric from the hot air is used for raising the temperature of the fabric to the temperature of the free water evaporation.
In the second stage, namely the constant-temperature drying stage, the temperature of the fabric is kept unchanged, and the evaporation speed of the moisture is also kept unchanged, so that the energy provided by the hot air is almost completely used for evaporating the moisture in the fabric, the evaporation efficiency is highest, and the evaporated moisture content is the largest.
And in the third stage, in the speed reduction drying stage, after the fabric reaches the critical water content, the evaporation rate of the water on the surface of the fabric is difficult to maintain, the actual evaporation area of the surface is further reduced, and a part of energy provided by hot air enables the temperature of the fabric to rise to the heat setting temperature.
The difference in time is not very significant when the lower the humidity of the air in the oven, the faster the fabric reaches heat-set, especially constant-speed drying, and when the higher the humidity of the oven environment, the slower the fabric reaches heat-set, and the oven humidity is below 10%. Meanwhile, under the condition of keeping other conditions unchanged, when the humidity of the oven is increased, the temperature of the fabric in the constant-speed drying section is increased, but because the humidity is kept low, more air needs to be discharged in the actual heat setting process, and energy loss can be caused. To achieve the proper heat-set processing time and reasonable moisture content, the ambient humidity should be maintained at a reasonable level.

TABLE 1 data before and after humidity control
| Oven temperature | Vehicle speed (m/min) | Humidity of oven | Fan frequency HZ | Steam valve opening | Quality of shaped fabric | |

The invention introduces a flue gas content laser online detection system into a hot air tentering setting machine 100.
The principle of the detection system is as follows: the scattered light intensity of light irradiating the particles has a monotone correlation with the geometric size, the geometric shape, the surface optical characteristics and other parameters of the particles, and for the particles of the pollution source with basically stable particle characteristics, the intensity of the scattered light of a particle set (particle cloud) is increased along with the increase of the total surface area of the irradiated particle set, and the scattered light intensity of the particle set is in a linear relation with the total surface area of the irradiated particle set.
Therefore, the gas to be measured is irradiated with the stabilization beam. The total surface area of the particle set can be estimated by measuring the intensity of the scattered light of the particle set, and the mass concentration of the particulate matters can be calculated through the density of the particulate matters on the premise of knowing the particle size number spectrum of the particulate matters. The oil smoke fine particles are a spherical particle aggregate with relatively stable constituent substances, the particle size distribution, the density and the surface optical characteristics of the oil smoke fine particles are relatively stable, and the oil smoke fine particles are ideal objects for measuring by a particle aggregate light scattering method. Through PID control program and the connection of the following fan, the smoke content is properly controlled, and the redundant heat recovery can be used for heating and drying the fabric at the front section. When the smoke concentration online detection probe detects that the tail oven 121 is higher than a certain safety value, the rotating speed of the exhaust fan 123 is increased, and otherwise, the rotating speed of the fan is properly reduced when the smoke concentration online detection probe is lower than the safety value. Therefore, the automatic control device is more controllable compared with manual operation of workers, saves energy consumption and reduces environmental pollution.
According to the experiment, after the air return device is adopted, about 20 percent of hot air can be discharged in an average day.
Ambient temperature: 25 ℃; the working temperature of the setting machine is as follows: 180 ℃, air supplement amount is about: 7000m3H is used as the reference value. Calculated according to the ratio of 20 hours per day and 6000 hours per year, the specific heat capacity C of the airP＝1.3kJ/m3。
The heat energy Q ═ VC can be saved every yearP(T1-T0)＝6000*7000*0.2*1.3*(180-25)＝1692600000kJ＝1692600MJ。
The saturated steam value is saved each year:
the humidity of the front-section oven 121 of the setting machine is indirectly detected by the oxygen content analyzer 125, and then the humidity of the oven 121 is improved by the control system, so that the energy consumption value can be effectively saved. The tail of the oven 121 at the rear half section of the setting machine is provided with a flue gas content laser online detection system, and the exhaust fan 123 is automatically adjusted by controlling the flue gas concentration in the oven 121, so that the purposes of energy conservation and environmental protection are achieved.
