The heat source system of machine is the case of steam thermophore heat source system, and its flash steam is incorporated to by flash steam recycling system
Indirect steam recycling system.
When the secondary dust-laden steam produced by an effect drying machine is not enough to drive two effect drying machines, indirect steam can be passed through
Replenishment system is supplemented.Indirect steam replenishment system is will to heat a heat source stream for imitating drying machine to be passed through an effect drying machine
In housing, it was changed into low pressure vapours, and had auxiliary desiccation to an effect drying machine, while to indirect steam recycling system
There is superheat protecting function, be unlikely to condense in deduster and pipeline of the dust-laden steam in indirect steam recycling system and block up
Plug, the pressure of the supplement steam of use is by pressure maintaining valve control.
The vent gas treatment of the two effect drying machine discharges used is completed by drying tail gas vacuum system, passes through wet dust removal
Enter condenser after device dedusting, after volatilization steam condensation, fixed gas is drawn by vacuum pump set.Tail gas vacuum system is set up and tieed up
The vacuum state in two effect drying machines, reduction and the volatilization temperatures for keeping material hygroscopic water in two effect drying machines are held.So that two
Imitate the thermal source of drying machine and treat that dry material keeps larger thermograde, improve two drying efficiencies for imitating drying machine.
The sealed feed system of use（Aqueous powder material, plaster pasty materials, liquid material）, be to have been sealed by material
Into.No matter charging carries out state or charging halted state, and its sealing state keeps effective.For aqueous powder material and cream
Pasty material and block filter cake material, sealed feed system are made up of distribution feed bin and cloth spiral.An effect is separately added into do
Dry machine and two effect drying machines, the control of feeding quantity are completed by automatic control system.
For liquid material, charging system is made up of charge pump, high-order voltage stabilizing hopper, pipeline and valve, is separately added into one
Drying machine and two effect drying machines are imitated, the control of feeding quantity is completed by automatic control system.
The pressure difference shielding system of use is made up of the gentle material stocking pipe of autocontrol valve, due to the dry material of an effect drying machine
Temperature be higher than temperature of charge in close drying machine, be loaded with certain heat, have auxiliary dry materials in two effect drying machines
Dry effect and heat energy utilization effect.So a dried heat-carrying dry material of effect drying machine will enter in two effect drying machines.One effect
The effect of the pressure difference shielding system of drying machine and two effect drying machines is that the dried heat-carrying dry material of an effect drying machine can enter
In two effect drying machines, but pressure difference isolation is carried out to an effect drying machine and two effect drying machines simultaneously, keep one to imitate drying machine and two effects
Drying machine is run under respective pressure field.The pressure difference shielding system of one effect drying machine and two effect drying machines is by control system control
System.
The two effect dried materials of drying machine used are by sealing discharging system discharge, by the gentle material stocking pipe of autocontrol valve
Constitute, it is the dried material material discharge of two effect drying machines that it, which is acted on, but keeps two pressure states for imitating drying machine simultaneously.

Road and valve are directly added into, and feed pressure and flow are by the valve regulated of sealed feed system, and feeding quantity is by automatic control system
Control；
2）, two effect drying machines（2）Charging：Two effect drying machines（2）For negative pressure drying, it is high-order that liquid treats that material is added by charge pump
Pressure stabilizing tank, high-order pressure stabilizing tank keeps stable material position pressure to treat that dry material adds two and imitates drying machine（2）, keep two to imitate drying machine
（2）The stabilization of feed pressure and flow；Feeding quantity is by automatic control system control；Add liquid object excessive in high-order pressure stabilizing tank
Material returns to storage tank by overflow pipe；
3）, charging carry out state or charging halted state, sealed feed system（12）One is all kept to imitate drying machine（1）Malleation
State is run and two effect drying machines（2）Negative pressure state is run；
So sealed feed system（12）It is made up of charge pump, high-order pressure stabilizing tank, pipeline and valve, and due to an effect drying machine
（1）Positive pressuring drying, two effect drying machines（2）For negative pressure drying, feed pressure is also variant.
