Multi media filter is a common equipment during filtration. Strict sealing performance needs to be ensured in the whole water treatment process. When filtering impurities, good sealing can be ensured to avoid the mixing of other impurities and filtration difficulties. Among many sealing methods, magnetic seal is more common. What kind of magnetic seal is it?

1、输送反应釜由于不用泵也不需降温，直接260℃输送反应釜，既节约了每釜加热量10万大卡，又节约了2小时生产时间，并且还在一定程度上提高了生产能力。

1. Since there is no need to pump or cool down, it is directly transported to the reactor at 260 ℃, which not only saves 100000 kcal of heating per reactor, but also saves 2 hours of production time, and improves the production capacity to a certain extent.

2、多介质过滤器由于磁力密封从而也无泄漏，这就使得设备在一定程度上减少了物料的泄漏浪费。

2. The multi-media filter has no leakage due to magnetic seal, which makes the equipment reduce the leakage and waste of materials to a certain extent.

3、由于设备无泄漏，其可控制的反应压力在3~3.5Mpa范围之内，在提高制备效果的同时也缩短了制备反应时间。

3. Since the equipment has no leakage, the controllable reaction pressure is in the range of 3 ~ 3.5Mpa, which not only improves the preparation effect, but also shortens the preparation reaction time.

4、采用插入管输送，不存在制备多介质过滤器底部堵塞及铝粉带入问题。

4. The plug-in pipe is adopted for conveying, and there are no problems of bottom blockage and aluminum powder in the preparation of multi-media filter.

5、由于利用压差输送，取消了高温多级泵不仅能够节省电、维修工并且还能够减少艰苦的维修工作以及昂贵的备品配件的费用。

5. Due to the use of differential pressure transmission, the cancellation of high-temperature multistage pump can not only save power and maintenance workers, but also reduce the cost of difficult maintenance work and expensive spare parts.

多介质过滤器的磁力密封借助磁力的作用，当设备开始使用的时候需要工作人员认真的做好相应的密封，这样可以保证过滤器的出水效果，其输送效果也会比较的好，进而也会使得水处理效果也好。设备的效率高了能够处理的污水也就会越多，同时也能够处理更多种类的污水。

With the help of magnetic force, the magnetic seal of multi-media filter requires the staff to carefully seal when the equipment is used, so as to ensure the water outlet effect of the filter, its transmission effect will be better, and then the water treatment effect will be better. If the efficiency of the equipment is high, more sewage can be treated, and more kinds of sewage can be treated at the same time.
