Pipe, airway tube is interior to be passed through airflow-distribution board and connects air inlet, the other end of airway tube filled with water suction filler, one end of airway tube
By taper pipeline connection eddy flow drying zone, the whirl cylinder of cylinder, the connection of taper pipeline are provided with described eddy flow drying zone
On whirl cylinder, the barrel of whirl cylinder is made up of the ventilation screen cloth of twice annular, filled with water suction between twice ventilation screen cloth
Filler, the inner side of whirl cylinder are provided with eddy flow air blast oar, and the outside of whirl cylinder is provided with annular ventilation slot, and described ventilation slot is with going out
Gas port is connected.
As a modification of the present invention, stop valve, described stop valve are provided between described ventilation slot and gas outlet
Return duct is provided with, stop valve is connected on air inlet by return duct；By ending the switch of control valve device, while when dress
Put and still contain steam gas in the natural gas of discharge, flowed back by return duct, carry out repeating dehydrating operations.
As a modification of the present invention, described stop valve is provided with water content detecting instrument, and described stop valve is electricity
Control stop valve；Pass through the switch of the switch and return duct of electric-control stop valve and water content detecting instrument accurate control device, manipulation essence
Standard, flexibly, steam is avoided to enter in follow-up production system.
As a modification of the present invention, the big opening end of described taper pipeline is connected on airway tube, taper pipeline
Osculum end is connected on whirl cylinder；The inner side of whirl cylinder will be all passed through by the gas of airway tube by taper pipeline, is passed through
Screw type air-flow, by gas under cyclonic action, uniformly through ventilation screen cloth, by absorbing water, filler is dried again.
As a modification of the present invention, described eddy flow air blast oar is arranged on the middle part of whirl cylinder, is provided with whirl cylinder
Multiple eddy flow air blast oars being connected in same root rotary shaft；It is each in order to ensure because whirl cylinder sheet is as certain length
Uniform eddy flow air-out effect on position, aeration operation is carried out by multiple eddy flow air blast oars.
The advantage of the invention is that：The present invention fills up water suction using more first by improving traditional dehydration device
The airway structure of filler, pending gas is evenly distributed, the problem of avoiding local filler from excessively absorbing water；Secondly led to using eddy flow
The further processing gas of mode of annular water suction filler to be crossed, further removes the steam remained in gas, steam removal efficiency is high,
The gas outlet of final unit is provided with detection means and return line, and the work of water suction filler is incomplete inside device, by returning
Flow tube road reprocesses, when absorb water packing material absorbing saturation after, be stopped, overhauled and maintenance work by stop valve, grasped
Make simply, control is accurate.
