Specific implementation mode
A specific embodiment, the not limited to this example of specific implementation mode is described below.
With reference to figure 1, throttling set import connects the outlet of high temperature and pressure room, and throttling set outlet connection low-pressure chamber import is empty
Air compressor import connects low-pressure chamber outlet, air compressor outlet connection high temperature and pressure room import.
Material is placed in low-pressure chamber, microwave source and infrared source is equipped in low-pressure chamber, microwave and infrared ray are for adding
Thermal material.
Due to the swabbing action of air compressor, low-pressure chamber will keep low pressure, and it is fast that low pressure is conducive to the moisture in material
Speed evaporation.
The heat that moisture is enough in material is supplied by heat transfer types such as heat radiations, so that evaporation and boiling is carried out at the same time, adds
Fast vaporization rate.
For example, when low pressure chamber pressure is 4.24KPa, the boiling point of water is 30 degree, and low pressure makes the boiling point of water reduce, material
Interior moisture movement and evaporation rate are accelerated.
Air compressor aspirates the indoor humid air of low pressure and compresses into high temperature and pressure room, and high pressure is conducive to improve wet sky
The dew-point temperature of gas makes humid air that can also be condensed into water at a higher temperature.
High temperature and pressure indoor location has dew point hygrometer, measures the dew-point temperature of humid air in high temperature and pressure room, and dew point temperature
Degree sends control device to；High temperature and pressure indoor location has circulating cooling water coil or circulating cooling air-coil, circulating cooling
Air themperature is equal to or less than dew-point temperature in the temperature or circulating cooling air-coil of water coil inner cold water, and vapor is made to follow
Ring cooling water coil or circulating cooling air-coil condensation moisture；The outer cooling water pump of circulating cooling water coil and hothouse with
And radiator is connected, circulating cooling air-coil is connected with the outer cooling fan of hothouse and radiator, and control device adjusting follows
The rotating speed of the internal circulating load of ring cooling water coil inner cold water or the cooling fan of circulating cooling air-coil, makes circulating cooling water coil
Air themperature is equal to or less than dew-point temperature in the temperature or circulating cooling air-coil of inner cold water；Humid air passes through high temperature and pressure
Become dry air behind room, dry air enters low-pressure chamber after throttling set and becomes Hot wet air heating across material, so recycles
Constantly the moisture of material is drained.
For example, dew-point temperature is 10 degree when normal pressure, when high temperature and pressure chamber pressure is 1MPa, pressure leak source temperature is increased to
55 degree, when the temperature of circulating cooling water coil inner cold water is equal to or less than 55 degree of dew-point temperature, vapor can be in circulating cooling
Water coil condensation moisture.
When low pressure chamber outer wall is made of the good material of heat-proof quality, high temperature and pressure room is made of the material of good heat-transfer,
High Temperature Moist Air becomes room temperature dry air behind high temperature and pressure room, and room temperature dry air becomes the dry sky of low temperature after throttling set
Gas enters low-pressure chamber and passes through material, and the moisture in material is made to be evaporated in the environment of low-pressure low-temperature.
With reference to figure 2, low-pressure chamber, throttling set and air compressor can be all mounted on high temperature and pressure chamber interior, due to dry
Air temperature after throttling set can reduce, therefore High Temperature Moist Air can be condensed into water in low pressure chamber outer wall, and heat
It is conducted to low-pressure chamber, the moisture in material is made to be evaporated in the environment of low pressure medium temperature.
Therefore, air compression throttling drying machine of the present invention has the function of low pressure middle temperature is dried and low-pressure low-temperature drying, with
And have the advantages that energy saving.
