Hemp mill humidifier, humidification, dust reduction and static electricity removal

Industry  Dehumidifier_PDGT Series

News on humidifying devices and dust and static electricity removal in hemp textile industry whether the temperature and humidity are reasonable or not has a great impact on the normal production of a hemp textile factory or enterprise; If the temperature and humidity of the workshop production environment are not appropriate, not only can we not produce high-quality linen products, but also may affect the normal operation of mechanical equipment. Humidity conditions are closely related to the hemp spinning process. Under different humidity conditions, their physical and mechanical properties will change to varying degrees. Before subsequent processing, the humidity of semi-finished hemp textiles is also important, which will affect the production of subsequent processes and directly affect the output and quality of finished hemp products

Therefore, in order to increase the spinnability of flax, the flax mill usually adds oil and moisture to the flax in the rear process of the softening machine to increase the moisture absorption rate of the flax fiber, thus increasing the flexibility and strength of the flax fiber, thereby reducing the friction coefficient and increasing the flexibility; Thus, the electric conductivity of hemp fiber is greatly increased, and the electrostatic phenomena and dust emission generated in the process of hemp spinning are reduced

Generally, the ambient humidity in the processing workshop of the linen mill should be kept at 60~70% RH; In particular, jute spinning requires more humidity, which must be maintained at about 75% RH! In a word, the temperature and humidity of linen mill are similar to those of cotton mill, but the difference is that the elongation of linen is relatively poor, and the softness is also worse than that of cotton mill; Therefore, the relative humidity of the linen mill workshop is slightly higher than that of the cotton mill, and other aspects can refer to the workshop humidity index of the cotton mill

In the past, some hemp textile manufacturers used the soil method of sprinkling water on the ground and under the machine stand. Although it can be slightly alleviated by only using air evaporation, it will make the ground messy, and the humidity is not stable and uniform enough to meet the real process requirements, affecting the production efficiency of the entire production workshop

In addition, some hemp textile manufacturers use water curtain air conditioners for humidification, but the investment in air conditioners is relatively large, and the later maintenance costs are also high; Moreover, the humidification effect is not very good. According to the survey, the humidification of air conditioners in workshops of different scales can only reach 30-50% of the standard humidity requirements, which is far from meeting the humidity requirements of hemp spinning process. Other hemp mills use high-pressure micro mist humidifier, which is easy to block and drip due to large atomized particles; It is too close to the machine, and the fog formed makes the computer board damp, causing misoperation or short circuit

To this end, the electrical appliances have been developed and produced_ The humidifier of linen mill and ZS series ultrasonic spray humidifier, after being used in factories or enterprises in the linen textile industry, have a significantly higher effect of humidification, dust reduction and electrostatic removal than similar humidification equipment, such as centrifugal, high-pressure micro fog, wet curtain, air cooler, steam water mixture, etc


  _ Hemp mill humidifier and ZS series ultrasonic spray humidifier products use the principle of ultrasonic high-frequency oscillation to achieve the purpose of uniform humidification;, For humidifiers of other humidification methods, it has significant advantages of [fine atomized particles], [low energy consumption], [high atomization energy efficiency], and [fast humidification speed]. With air humidification, purification, anti-static and dust prevention, cooling, dust reduction and other purposes; It can not only uniformly humidify large space, but also compensate local humidity in special space, with high flexibility. Welcome to inquire the details of humidifier, humidification, dust removal and static electricity removal in linen mill

  _ Control mode of hemp mill humidifier and ZS series ultrasonic spray humidifier, technical parameters:

◎ Model selection reference: there are many factors to be considered in the model selection of humidifier, such as indoor space size, ambient temperature, equipment heat, ventilation, and air conditioning exhaust, which will affect the indoor environment humidity and humidification effect. In general, a certain margin should be left when calculating the humidification amount, that is, the corresponding humidification amount should be increased, Moreover, the required humidification amount and corresponding humidifier model in the space shall be comprehensively calculated from low humidity humidification to ideal humidity range.

To sum up, of course, the relative humidity of the workshop environment in the production and processing process of the hemp mill cannot be too high, otherwise the friction coefficient of the hemp fiber will also increase; Moreover, the gum in the hemp fiber is sticky due to its high moisture absorption, which makes it difficult to loosen and comb the fibers due to the stickiness between fibers, and even causes the phenomenon of sticking around the roller. Therefore, it is required that the relative humidity of the workshop environment in the hemp mill should be controlled stably within the most appropriate range

Generally, according to the different raw materials of hemp spinning, if the relative humidity is kept between 60% - 70% RH, the transportation failure of raw materials, wire breakage loss, and weight loss and quality grade reduction during storage will occur; At the same time, a series of problems affecting normal linen spinning process, such as dust and wool caused by low humidity, can be completely avoided
