The melt blown heater has an advanced structure

After experiencing this difficult period of pneumonia epidemic, I believe many friends in the future will have their parents keep a few packs of masks on hand to prevent situations where they spend a lot of money to buy masks again. Today, air heater manufacturers will come to talk to you about the machine for making masks - the melt blown heater. It uses high-speed hot air flow to stretch out the polymer melt flow from the extrusion die nozzle hole, forming ultrafine fibers, which are gathered on the condensation mesh or roller and bonded into melt blown nonwoven fabric. What are the performance characteristics and power consumption of melt blown pipeline heaters? Today, we will introduce the melt blown pipeline heater. Firstly, let's take a look at the performance characteristics of the melt blown pipeline heater:

1. Performance characteristics of melt blown heaters

1. The melt blown heater has an advanced structure, high thermal efficiency, good mechanical strength, wear resistance, and corrosion resistance.

2. The melt blown heater can heat the air to a very high temperature, up to 450 ℃, and the shell temperature is only about 50 ℃.

3. The melt blown heater has high efficiency: up to 0.9 or higher.

4. Fast heating and cooling speed, up to 10 ℃/s, with fast and stable adjustment. There will be no lead or lag.

5. The melt blown heater has the advantage of easy installation and disassembly.

Under the condition of not violating the usage regulations, the pipeline electric heater is durable and can have a service life of several decades.

7. The melt blown heater has clean air and a small volume.

2. Power consumption of melt blown heater, i.e. power calculation

To calculate the power of the melt blown heater, we need to know several parameters: flow rate, initial temperature, and heating temperature. Understanding these parameters can calculate the power of the air heater.

The formula is: flow rate (kg/s) * 1.29 x 1.009 * (to be heated - initial temperature) * 1.3.

The air density is 1.29, the specific heat of the air is 1.009, the required heating degree - exceeds the starting temperature=temperature rise, and 1.3 is the safety factor.

Overall, based on the actual situation, it can be seen that the application direction of melt blown electric heaters in China is still relatively small, far from mainstream electric heaters such as radiation electric heaters, air electric heaters, and heat treatment electric heaters.
