[0029] Two groups of condensate pipes 201 are fixedly installed on the outside of the cooling box 2, and a steam pipe 202 connected to the top of the box body 1 is fixedly installed on the top of the cooling box 2. A controller 5 is fixedly installed on the top of the front of the box body 1, and a display screen is fixedly installed on the front of the controller 5.

[0030] After the device is installed at the designated installation position, the operator transports the raw material to the storage box 101, and then the storage box 101 can be used to store the tetrahydrofuran raw material.
