Batch Heat Pump Sludge Dryer Definition

It Is a Device That Uses The Refrigeration System To Cool And Humidify

The Hot And Humid Air While Recovering The Air Moisture By The Heat

Pump Principle To Condense The Latent Heat.
Dehumidification Heat Pump = Dehumidification Drying+ Heat Pump (Energy Recovery) Combined

A. Dehumidification

The Moisture Contained In The Air Is Different Under Different Working Conditions. When The Air Cools Down, The Water Vapor In The Air Gradually Condenses And Reaches a Saturated State. When The Dew Point Of The Air Continues To Decrease, The Water Vapor In The Air Becomes Condensed Water And Precipitates, So That The Absolute Water Content In The Air Is Reduced. Air Achieves The Dehumidification Process

B. Condensation

It Is The Gas That Turns Into a Liquid When It Is Cold, Such As Water Vapor Turns Into Water Condensation Heat - The Latent Heat Of Phase Change Refers To The Heat Absorbed Or Released From One Phase To Another By a Unit Mass Of Material Under Isothermal Isostatic Conditions. Solid, Liquid-Melting Heat (Or Solidification Heat), Liquid, Gas-Vaporization Heat (Or Condensation Heat), Solid, Gas-Sublimation Heat (Or Condensation Heat) 。

Working Principle

Utilizing The Dehumidification Principle Of The Low-Temperature Heat Pump, The Sludge Is Dried By Convective Hot Air, So That The Moisture In The Material Absorbs Heat And Evaporates Into The Air To Achieve The Purpose Of Reducing The Moisture Content. It Use The Refrigeration System To Cool The Hot And Humid Air Below The Dew Point To Precipitate Moisture, And Then Heat The Air Through Multiple Heat Recovery Technologies To Keep The Moisture In The Sludge Evaporating,

Evaporation-Dehumidification-Heating-Evaporation-Re-Dehumidification,

In Fact It Is Equal To The Organic Combination Of Dehumidification Heat Pump + Heat Recovery Technology + Material Delivery System.
