Types and working principles of industrial humidifiers

Industrial humidifier refers to a humidifier system that is professionally used in industrial fields and central air conditioning. The difference from the civil humidifier is that its humidification capacity is large and the humidity can be fully controlled. With the increase of high-tech multinational enterprises in the country, more and more fine chemical, precision electronics, precision casting, textile and chemical fiber industries will put forward stricter requirements on the environmental air humidity control of the production process to make the production process The air humidity in the environment reaches the technical level. Therefore, how to choose the corresponding industrial humidifier according to the actual situation and humidity requirements is a difficult problem for the enterprise purchasing supervisor. How to choose an industrial humidifier that meets the needs of the company's product production process?

 In the chemical fiber, textile, precision casting and other industries, the usual requirements for ambient air humidity, such as cooling, dusting, and preventing static electricity are the humidity adjustment goals of industrial humidifiers. Industrial humidifiers are mainly divided into the following categories according to their working principles:high-pressure micro-mist humidifier is composed of five parts: main machine, special micro-mist nozzle, branch control system, high-pressure pipeline transmission system, and ultra-fine water supply filter system. When working, the high-pressure ceramic plunger pump in the main engine pressurizes the filtered water supply to 7MPa; then through the high-pressure transmission pipeline to the ultra-fine mist nozzle, after atomization, the 1--10μm fine particles are sprayed into the entire space. The mist absorbs heat in the air and vaporizes to increase the water content of the air, thereby meeting the humidification requirements. The fine particles will absorb part of the air heat during gasification, which can also play a role in reducing the ambient temperature.

Ultrasonic humidifier, with fine atomized particles, fast absorption by air after atomization, and easy installation and maintenance, it ranks first in the popularity of various industrial humidifiers. The ultrasonic humidifier can choose to use a ducted air supply method to send the atomized humid air into the space, which has the effect of humidification, cooling and dust reduction. The available industries and environments are very wide, covering almost all aspects of industrial and agricultural production. The customer's recognition is very high and it is very popular and favored.

 Centrifugal humidifier, the humid air particles after atomization are slightly larger, but this model is easy to use and low maintenance cost in the future. Centrifugal humidifiers can be divided into hand-push mobile type and hanging type. It is very convenient for customers during the experiment. This is the advantage of the centrifugal humidifier. In addition, the mobile hand-push type comes with a water tank, which is suitable for humidifiers that are inconvenient to set up water pipes and automatically feed water. The hoisting centrifugal humidifier can rotate 120 degrees to supply air, and the air supply and humidification surface is wide, and the hoisting does not occupy the ground. It is used as a workshop to reduce temperature and dust.

 Wet film humidifiers are mainly characterized by isenthalpic humidification, fog-free humidification, and stable humidification. They are used in environments that require fog-free humidification, such as the electronics industry, fine chemicals, laboratories, archives, and offices. They are also energy-saving and environmentally friendly when used as cooling. The characteristics of the environment are also more significant.

 How to choose an industrial humidifier needs to be combined with the requirements of the use situation and the advantages and characteristics of the humidifier itself. Must not be indiscriminate, as long as it can be humidified. In this way, neither the characteristics of the product nor the advantages of the corresponding humidifier products are taken into account, and the effect of energy saving, environmental protection and equipment use is not achieved, which is not desirable.
