Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1.A kind of combination unit for being used to dry fresh chloromethanes, including sulfuric acid dehydrating tower 1, calcium chloride dewatering box
19th, sulfuric acid circulating pump 6, the first control valve 8, the second control valve 11, liquid flowing line 3, the first flow line 4, the second flow line
18th, the 3rd flow line 22.The bottom of sulfuric acid dehydrating tower 1 is provided with liquid outlet 7, unloads liquid mouth 9, fluid infusion 10, the first air inlet 5,
Top is provided with inlet 2, the first gas outlet 17.Consider from cost, favourable anti-corrosion and maintenance convenience etc. is reduced, sulfuric acid dehydrating tower 1
Using packed tower.The liquid feeding end of sulfuric acid circulating pump 6 is connected by liquid flowing line 3 with liquid outlet 7, outlet end passes through liquid flowing line 3
It is connected with inlet 2.For enhanced corrosion resistance energy, sulfuric acid circulating pump 6 uses fluoroplastics lining magnetic drive pump.First control valve 8 is logical
Cross liquid flowing line 3 and be connected with unloading liquid mouth 9.Second control valve 11 is connected by liquid flowing line 3 with fluid infusion 10.First flow line
4 are connected with the first air inlet 5.Calcium chloride dewatering box 19 includes casing 28, and the side of casing 28 is provided with chamber door 23.Chamber door 23 is provided with
It is easy to observe the strip flint glass of calcium chloride dewatering box interior change.Air tight to ensure, the sealing of chamber door 23 is absolute
