Preferably, the outer casing bottom is provided with condensation-water drain；Be conducive to a part of steam to be condensed into after water from condensation
Water out is discharged.
Preferably, the steam inlet duct is connected with a mixing chamber, the mixing chamber connect respectively furnace gas exhaust pipe and
Cold air pipe, and temperature inductor is provided with mixing chamber, mixing chamber lateral wall is provided with temperature indicator.Using producing sulfuric acid
The high-temperature furnace gas produced during ammonium enters as Preheated steam from steam inlet preheats material liquid, without extra generation
Steam, is greatly saved the energy, energy saving and environmentally friendly, since furnace gas temperature is higher, in order to avoid raw material mass pipe in snake pipe,
Mixing chamber is set, high-temperature furnace gas is mixed with cold air, while set temperature inductor, steam temperature in mixing chamber is monitored at any time
Degree, it is excessive to avoid enter into vapor (steam) temperature in vapor chamber.
Preferably, the material liquid outlet tube is connected with flow valve and circulating pump in turn.The setting of flow valve is to control
The flow velocity of material liquid in snake pipe processed, the too fast pre-heat effect of raw material flow velocity is bad, and flow velocity is excessively slow to delay again；Circulation
Being provided with for pump is beneficial to extract bulk pharmaceutical chemicals in snake pipe out.
The beneficial effects of the utility model are as follows：
1. preheater design is ingenious in the utility model, simple in structure, and without additionally producing steam, preheating is uniform, in advance
Thermal effect is good, and preheating time is fast；The utility model is set in snake pipe into material liquid, if steam from steam inlet directly into
Enter preheater, the pipeline in preheater can hinder the transmission of steam so that one end steam close to steam inlet is more, away from steam
One end steam of entrance is few, causes preheating time to be grown, and preheating is uneven, and pre-heat effect is bad；By setting vapor chamber and ventilation
Hole, and both sides set steam inlet, enable steam quickly to enter in vapor chamber, then can uniformly quick the by venthole
Inner casing is full of from the entrance around inner casing, to being preheated in inner casing to the material liquid in pipeline so that pre-heat effect is good, preheating
Speed is fast, and preheating is uniform.
