Industrial Humidifier

Industrial humidifier

Industrial humidifiers, as the name suggests, refer to humidifier systems that are professionally used in industrial fields and central air conditioning systems. The difference from civilian humidifiers is that they have a large humidification capacity and can achieve fully automatic humidity control; In addition, different large-scale industrial humidifier systems can be used according to different sites. Industrial humidifiers can be divided into central air conditioning humidifiers and commercial humidifiers.

Development Overview

Humidity, as one of the main parameters of air, is closely related to people's lives and production. People live in50～60%It feels comfortable in a humid environment, otherwise it may feel dry or stuffy. In the textile industry, humidity is lower than40%It is easy to break the yarn; The humidity in the tobacco industry is higher than70%It is prone to mold growth, and when the humidity is below30%Highly prone to static electricity, which is extremely detrimental to the electronics industry. With the development of modern air conditioning technology, The technology of air humidity regulation and various humidification and dehumidification equipment have also been developed. Our country is60Since the beginning of the era, there has been an emphasis on the research and development of dehumidification equipment, including temperature rise dehumidification, rotary dehumidification, and low-temperature condensation dehumidification, and their products have been widely used in China.

But humidification technology has been used until70At the beginning of the era, it was still limited to water spraying humidification and electrode humidification. With the development of technologies such as textiles, electronics, printing, tobacco, and special reserves, and the continuous improvement of people's requirements for comfortable living environments, A new challenge has been proposed for humidification technology,70In the late 1970s, steam humidification technology was widely used, and dry steam industrial humidifiers were successfully tested. arrive80With the further exchange of technology between China and foreign countries, advanced technologies such as centrifugal humidification, ultrasonic humidification, and far-infrared humidification have made significant progress and have all been commercialized.80At the end of the s, new products such as high-pressure spray type industrial humidifier, new electrode type industrial humidifier, wet film type industrial humidifier appeared. Nowadays, there are many varieties of industrial humidifiers with different performances. When choosing an industrial humidifier, users should choose based on factors such as product performance characteristics, humidity requirements, and usage scenarios.

According to humidity requirements, we divide humidification into two types: process humidification and comfort humidification:

The importance of air humidity is increasing in modern industrial production and scientific experiments, and the requirements are also becoming higher. If the humidity cannot meet the requirements, it will cause varying degrees of adverse consequences. For example:

1The humidity requirements for places such as electronic factories, semiconductor factories, programmable control rooms, and explosion-proof factories are generally within40%~60%RHIf the relative humidity is not sufficient, it will cause an increase in static electricity, resulting in a decrease in product yield, damage to chips, and even explosions in some explosion-proof places,“Electrostatic bombardment”The harm caused is incalculable when the air humidity is below40%RHIt is highly prone to static electricity, although people have taken many measures to remove static electricity and increase air humidity45%RHThe above is absolutely effective.

2The humidity requirements for places such as textile factories, printing factories, and film factories are generally high, generally greater than60%RHThe humidity requirements for textile factories are generally within50%~85%RHDuring the yellowing process, high humidity is required to prevent static electricity, and during the spinning process, high humidity is needed to prevent saltpeter crystallization. The moisture content of cotton fibers directly affects their strength. In short, the air conditioning in the textile workshop is mainly focused on ensuring the relative humidity required for the process. Insufficient humidity during printing and film production can cause problems such as inaccurate color matching, paper shrinkage and deformation, paper adhesion, and decreased product quality.

3The humidity requirements for precision machining lathes and various measuring rooms are generally within40%~65%RHBetween precision bearing precision machining, high-precision engraving machines, mechanical measurement rooms, electrical measurement rooms, etc., if the humidity is not sufficient, it will cause a decrease in the accuracy of the processed products and distortion of the measurement data.

4The humidity requirements for product coating workshops are generally greater than65%RHIf the humidity is not sufficient, it will cause problems such as decreased adhesion of paint to metal or plastic, uneven spraying, and decreased surface smoothness.

5The requirements for humidity in pharmaceutical factories, operating rooms, and other environments are even more necessary, and clean humidification is necessary. If the humidity is not enough, it will cause problems such as a decrease in drug grade, an increase in bacteria, and difficulty in wound healing.

6In addition, high humidity requirements are required in places such as cigarettes, cold storage preservation, food moisture regain, aging experiments, cultural relic preservation, gravity testing, protective decoration, and rehabilitation centers. With the development of modern industry, humidification in air conditioning engineering will become increasingly important. Although the humidification time required in some southern regions is very short, some only1—2Months, but as long as the process requires and the quality of the produced products remains unchanged, the issue of humidification must be considered.
