1 overview, textile workshop air conditions
Air condition refers to the temperature, humidity, air flow velocity, dust concentration and freshness (hereinafter referred to as \"five degrees\"). Air condition and textile technology, there is a close relationship between human health.
First of all, the air condition is closely related to the textile processing. Due to the textile industry has its own characteristics, namely the use of raw material is fiber (natural fiber and chemical fiber), various kinds of fiber under the condition of different degrees of temperature humidity chamber, their physical properties and mechanical properties (such as moisture regain, strength, elongation, flexibility, and electrical conductivity, etc.) will produce different degree of change, a direct impact on textile production situation of each working procedure. If the temperature and humidity control is bad, will worsen the production status and directly affect the production of semi-finished products and finished products and quality, and humidity control in the \"five\" is especially important. (schedule: the effect of temperature and humidity on the all kinds of textile process and should be controlled in the range).
Second air condition not only affect the worker's physical condition and health, but also affect their emotions and production efficiency. Need to keep the heat balance between the human body with the surrounding environment, it is very important to people's health and comfort. People in the labor produce a lot of heat, need to constantly put it out, to maintain normal body temperature, the human body to maintain body temperature normal function is called a \"temperature regulation\". Cooling mode, including sensible heat radiator (radiation, convection and conduction) and latent heat (evaporation). The situation of the heat and the temperature of the surrounding air, humidity, flow rate has a close relationship.
(1). The influence of the temperature. If the surrounding air condition hinders the human body into the surrounding air cooling, will aggravate the temperature regulating mechanism of nervous activity and make people feel uncomfortable, even can destroy heat balance.
(2). The effects of relative humidity. In the summer, the relative humidity affects the main body of the strength of the evaporation cooling. Especially in high temperature, the effect is more significant. Under the condition of the same high temperature, for example, if the air is very humid, water evaporation is difficult, so feel hot.
(3). The influence of the air flow rate. The size of the air flow velocity also affect the body's heat dissipation, the increasing of air velocity, would lead to skin surface evaporation heat increase, sweat easy evaporation, convection also increases at the same time, the body's heat quickly, so as to make the person feels cool. (make a person feel very comfortable temperature and wind speed see table below) the relation between temperature and wind speed corresponding table temperature t v (242526272829303132 ℃), wind speed (m/s) 0.150.290.410.510.670.800.931.061.19 -- through the above analysis, make the person feels cold or hot, no separate depends on air temperature of high and low, also with the air relative humidity and related to the size of the air flow rate. Clearly the different combination of these factors, we can give a person with a sense of the same cold and hot, often put these three factors on the human body comfort of comprehensive effect is called the effective temperature.
(4). The effect of dust concentration. Every workshop of textile produce dust, these dirt came mainly from short fibers, fuzz, etc, and mineral dust. Dust contamination skin easily, especially when summer sweat, dust easily clogged pores and cause many diseases, especially the textile occupational disease \"cotton flock AD cool-headed disease\".
(5). The influence of freshness. Freshness is refers to the harmful gas and odor, concentration of carbon dioxide in the air and the concentration of air negative ions. Before the three concentration is too high, can make the person feel discomfort and nausea, should be timely eduction, supplement of fresh air. The determination of the freshness of the air, the main sign is a negative air ion air negative ions. Practice shows that the people working in an environment of air negative ions seldom generally appear dizziness, headache, fatigue, chest tightness, high blood pressure, distracted look sick. The main method is to use the artificial air anion ultrasonic transducer, make water of air negative ions formed under high speed oscillation.
2, ultrasonic industrial air humidifier application in textile workshop air conditions
(1). When used alone, increase the humidity of the air. This product is on the basis of absorbing foreign advanced technology, after years of development and production test of a new type of spray humidification equipment. It adopts advanced change ultrasonic atomization technology for ultra small droplets reached less than 10 microns, will not fall on the ground. Droplets through the air by the fan blow out and evaporation, to improve air relative humidity. No water droplets phenomenon, atomization and range. Simple and reasonable structure, stable performance and reliable (because of its simple failure rate is extremely low); Strong adaptability to water quality, water pressure, no special requirements; Easily installed, no need to modify workshop; Easy to use, compared with foreign products, more use of the high quality of stainless steel raw materials, to overcome the imported products in use process is easy to scale, difficult to clean, and the price is only 1/3-1/2 for it.
It can evenly segments on top of a workshop, the realization of the entire humidity adjustment, can also be installed in a humidification of individual need, realize the regulation of local humidity. By adjusting the amount of spray, which can be very simple humidity adjusting quickly. If used with humidity control instrument, can easily achieve automatic control of humidity.
(2). When used with exhaust fan, lowering the temperature in summer.
Water can absorb heat in the process of evaporation, and evaporation is closely related to temperature, evaporating surface area and wind speed. Because this equipment makes the water had changed into very small fog particles, greatly increased the evaporation surface area, thus evaporation increases greatly. When used with heavy traffic exhaust fan, can increase the flow of air velocity (advisable) to human body comfortable wind speed, this will further increase evaporation, take away the workshop a lot of heat energy to reduce the temperature. If using the deep well water or cooling water, the effect will be even more significant.
In actual use, ultrasonic industrial air humidifier and exhaust fan system generally adopts the negative pressure longitudinal ventilation method, the ultrasonic longitudinal side industrial air humidifier installation in the workshop and to set aside enough inlet, exhaust fan installed in the workshop to the side. Ultrasonic industrial air humidifier to micro fog into the workshop, the exhaust fan is running at the same time, to produce negative pressure in the workshop, to make the external drying, unsaturated air suction in the workshop, accelerate the evaporation of moisture, absorb a lot of calories, reduce indoor temperature, after discharge from one side of exhaust fan workshop. At runtime, the system will continuously cooled fresh air into the shop, improve the indoor environment. Using the system in hot summer, can reduce the workshop temperature 4-10 ℃, the air is dry, the higher the ambient temperature, cooling effect is obvious.
By wet, ultrasonic industrial exhaust fan air humidifier and large flow of the prominent advantages of this system is that due to lower moisture evaporation temperature of the workshop, and adjust the humidity, wind speed was increased, the body feeling comfort greatly improved, and large flow exhaust fan out of the dust and harmful gases, odors and carbon dioxide, reduce the dust density, and in the process of ultrasonic industrial air humidifier atomization, spread out a large number of air negative ions, greatly improving the fresh air, thus greatly improving the environment air conditions (the \"five degrees\").
3, with the usual way to improve the workshop air condition
From the point of view of technology management, as a result of industry technology between mutual fusion, often leads to research from different angles on the same issue, and appeared in a research perspective has a breakthrough, in a row has very mature technology, and other industries but it has not been widely used, but still focus on its original Angle of research, the society is a waste of resources.
In terms of ultrasonic industrial air humidifier, originally applied to agricultural cooling, humidification, its stable performance, low cost, excellent cost-effective, has been confirmed by practice. From the traditional textile industry central air-conditioning room spray cooling, humidification, compared different research Angle, the whole workshop as the research object, the former overall cool wind field, while the latter is the local as the research object, through the air supply pipe to realize local cooling. Objectively, of course, compared with the large centralized central air conditioning system, industrial air ultrasonic humidifier is hard to realize heating drop wet, but in to achieve fast and Jane humidification, low investment, low running cost, realize the humidification and cooling, improve the working environment has incomparable unique superiority, especially suitable for small and medium-sized textile enterprises. For large textile mills, with the central air conditioning system, also can greatly reduce operating costs, improve product competitiveness.
So the textile workshop with wet, ultrasonic industrial humidification machine is a good choice!
