In order to prevent water mist from being carried out, a dehydrator (also known as a droplet separator) should be set at the outlet of the wet dust collector. In some wet dust removal equipment, the dehydrator directly affects the dust removal efficiency. Such as cyclone dehydrator of venturi dust collector.

In almost all of them Wet dust collector The amount of water mist carried by the purified gas depends on the flow rate of the equipment section and the atomization mode in the dust collector.

In order to prevent water mist from being carried out Wet dust collector A dehydrator (also known as a droplet separator) should be set at the outlet of. In some wet dust collectors, the dehydrator directly affects the dust removal efficiency. for example Venturi dust collector In order to achieve the necessary dust removal efficiency, the venturi tube is mainly used for condensation, and the condensed dust water is cleaned up by the dehydrator. In addition, if the dehydrator is not set up or the dehydrator works badly, the purified air will carry a large amount of water drops directly into the ventilation and dust removal system, which will cause pipe blockage, increase the maintenance amount of pipes and valves, and affect the normal operation and service life of the fan

The dehydrator is generally set in two ways: one is set inside the precipitator and becomes a part of the precipitator, such as Water bath dust collector The upper water baffle; the other is set outside the dust collector to become a separate device, such as Venturi dust collector Cyclone dehydrator.

There are four commonly used dehydrators.

(1) The inertia dehydrator is set at the outlet of the dust remover, with low resistance Wet dust collector It is widely used.

(2) Elbow dehydrator uses centrifugal force to throw water drops out, which can be used in venturi dust collector.

(3) The cyclone dehydrator can be used to remove fine water drops with high dewatering efficiency.

(4) Cyclone plate dehydrator uses centrifugal force to dehydrate, which is usually set at the outlet of dust collector.
