Melt blown non-woven fabric electrostatic generatorWorking principle:

The electrostatic generator is composed of an electrostatic emitter (rod) and a DC high-voltage power supply. The DC high-voltage power supply provides negative (or positive) high voltage to the electrostatic emitter (rod), causing it to emit negative (or positive) electricity and then charge the object (workpiece) (artificial charging). The higher the voltage, the larger the effective range.

Product features:

The readings of voltage, current, time, status information, and prompt information are clear and intuitive;

● Full Chinese interface, simple and clear operation, suitable for various application scenarios;

● Light touch button operation, all functions can be set through buttons, improving the safety and reliability of the product;

The fully digital calibration method eliminates the outdated potentiometer adjustment, making it extremely convenient for on-site use and easy to control accuracy (this function comes with password protection);

● Press the button to directly set the transformation ratio of the test transformer (this function is password protected). When connecting testers of different voltage levels, it can be flexibly applied, truly achieving a control box that can be matched with multiple transformers;

● Status reminder function, fully Chinese guided operation, can be proficiently operated even without instructions;

During the experiment, there is a flashing high-voltage symbol displayed on the screen, constantly reminding operators to pay attention to safety;

● Test result display function, which can automatically determine the test results (pass or fail), and can reliably record the voltage of the test sample during overcurrent, flashover or breakdown;

● Sound alarm function for test results. When the test passes or fails, the equipment will emit different alarm sounds, and the test personnel can directly recognize the test results from the alarm sound;

● Pause function, during automatic control, this function can achieve the pause of voltage rise or fall at any point, and the pause time can be flexibly controlled by the testing personnel, making it convenient to observe the status of the test sample;

● Automatic timing function. When the voltage automatically rises to the set value during automatic control, the equipment automatically starts timing. When the timing time is up, the test results are displayed and the equipment automatically returns to zero position;

● Manual timing function, when manually controlled, the timer can be manually started, and when the withstand time is up, the device will automatically return to zero position (only desktop devices have this function);

● Manual control mode, which is similar to the traditional electric up/down mode. The up/down is controlled by buttons, and the device automatically determines the upper/lower limit with overvoltage protection;

Intelligent control of boost speed, when the voltage reaches 80% of the target voltage, the boost speed will automatically slow down, and when it reaches 90% of the target voltage, the boost speed will further slow down;

Adopting a combination of hardware and software anti-interference technology, the performance is stable and the anti-interference ability is strong.

Non woven meltblown fabric electrostatic polarization generator (120KV polarization machine)Installation and use:

1. Grounding: Ground the output grounding terminal of the DC high-voltage power supply to ensure that the resistance between the DC high-voltage power supply casing and the ground is less than or equal to 10 Ω.

2. Connect to high voltage: Insert the high voltage input plug of the ion emitter (rod) into the output socket of the DC high voltage power supply, and lock it with the screw provided on the high voltage plug.

Since the outbreak of the epidemic, with the increase in domestic production capacity, there has been a strong demand for key raw materials such as meltblown fabrics. Moltblown nonwoven fabrics treated with electrostatic polarization have the advantages of high filtration efficiency and low filtration resistance due to their persistent static electricity, which can capture fine dust through electrostatic effects. At present, electrostatic polarization equipment in the melt blown non-woven fabric industry has been widely used in various non-woven fabric manufacturers and equipment manufacturers. The melt blown fabric electrostatic generator and melt blown fabric electrostatic polarization equipment are accelerating their supply to assist in the production of melt blown fabric.

The following points should be noted for the electrostatic generator of meltblown fabric:

1. Good operational performance, the magnitude of voltage and current determines the adsorption force of meltblown fabric

2. Stable and reliable. Due to the unstable operation of the equipment under high voltage, it is highly susceptible to damage.

3. Ensure the safety of the non-woven fabric electrostatic generator, which is a high-voltage device. Improper selection can pose a risk of electric shock to the human body.

Both too large and too small can affect the production process of meltblown fabric. The use of non electric shock technology, overload protection technology, and continuously adjustable voltage and current technology is the preferred choice for non-woven meltblown fabric with electrostatic equipment.

principle

Electrostatic precipitator utilizes the effect of an electrostatic field to charge and adsorb suspended dust particles in a gas, and separate them from the flue gas to remove them. This is the main aspect of electrostatic applications, which can be used for flue gas dust removal in various factories. The structure of the electrostatic dust removal device is: the rod-shaped or filamentous high-voltage discharge electrodes are insulated at both ends and suspended between the grounded flat plate dust collection electrodes or on the axis of the grounded cylindrical dust collection electrode. Negative high voltage is applied to the high-voltage discharge electrode. When the corona initiation voltage is reached or above, a purple light spot appears on the surface of the high-voltage electrode, and a hissing sound is emitted. When gas containing dust or smoke is introduced, particles such as dust and smoke are directly charged due to the action of negative ions. Under the action of the electric field, they are adsorbed on the dust collection electrode and accumulated, and the purified gas is extracted from it. The accumulated dust falls off when tapping the dust collector and needs to be removed. Compared with general dust removal methods such as centrifugal force separation, cleaning, and filtration, electrostatic precipitators have higher dust removal efficiency, generally reaching over 95%, and some reaching over 99%. It can capture particles larger than 0.01 microns, with a wide range of dust removal particle sizes, and the dust can be dry or wet. The pressure loss of the device is relatively small, usually 10-20 millimeters of water column. It is easy to maintain and costs less. It can handle corrosive gases or dust and can be subjected to high-temperature exhaust treatment, generally up to 350 ℃. Special designs can reach up to 500 ℃; Low power consumption and large gas processing capacity. For a thermal power plant with a generation capacity of 1 million kilowatts, the processing capacity of flue gas can reach several million cubic meters per hour. But for devices with small gas processing capacity, the initial cost is higher; For various types of dust, dust removal conditions must be adjusted, and explosion-proof measures must be taken when dealing with combustible gases.
