When can influence the safe operation of electrical equipment, so needing to absorb the acidic materials in sulfur hexafluoride gas.The patent No.
Sulfur hexafluoride gas middle acid substance and hydrolyzable Absorption of Fluoride dress are disclosed for the Chinese patent of " CN2015202422065 "
Put, its technical scheme is：Including the gas absorption cell equipped with absorbing liquid, gas absorption cell is the slim-lined construction placed vertically, is inhaled
Receipts liquid is certain density NaOH solution, and the bottom of gas absorption cell is connected with air inlet, and top is connected with exhaust outlet and pressure
Detector.The utility model has the characteristics of easy to operate, absorption efficiency is high, solution usage is few, and defect is：1st, do not examine in real time
Survey absorption process function, it is difficult to which guarantee fully absorbs to gas middle acid substance；2) sulfur hexafluoride gas is relied solely on from gas
Body absorption cell bottom enters, absorbed by NaOH solution, and absorption efficiency is needed further improvement and improved.
Utility model content
The purpose of this utility model be to provide one kind can overcome drawbacks described above, it is simple to operate, have in real time detection absorbed
Cheng Gongneng, the high device for being used to absorb sulfur hexafluoride gas middle acid substance of absorption efficiency.Its technical scheme is：
It is a kind of to be used to absorbing the device of sulfur hexafluoride gas middle acid substance, including slim-lined construction and the absorption placed vertically
Pond, it is characterised in that：Absorption cell is multiple using structure identical, and cross section is in a tubular form；For each absorption cell, absorption cell
Bottom be provided with the leakage fluid dram with valve, the bottom in absorption cell is provided with stirring magneton and pH detectors, and absorption cell is close to bottom
Side wall be provided with air inlet, the side wall of absorption cell upper end is provided with gas outlet, and the top in absorption cell is provided with atomizer, mist
Change the liquid feeding end of shower nozzle respectively through setting valvular pipeline communication NaOH solution, connecting absorption cell through the water pipe provided with hydraulic pump
Bottom, the liquid inlet and outlet end that water pipe is located at hydraulic pump are equipped with valve；Along gas direction of travel, the air inlet of first absorption cell
Sulfur hexafluoride source of the gas is connect, the air inlet of next absorption cell connects the gas outlet of a upper absorption cell through air flue.
The described device for being used to absorb sulfur hexafluoride gas middle acid substance, absorption cell have 3~5.
Its operation principle is：The hydraulic pump and valve closed at the beginning on water pipe, the valve on NaOH solution pipeline is opened,
NaOH solution enters through atomizer each absorption cell and to be sprayed downwards, and sulfur hexafluoride gas to be absorbed is from first absorption cell
Air inlet be passed into the bottom of absorption cell, reach the top of the absorption cell through NaOH solution in first absorption cell, then by
The gas outlet of the absorption cell is passed into the bottom of next absorption cell, the like.When the NaOH solution in absorption cell reaches regulation
During amount, the valve on closing NaOH solution pipeline, the hydraulic pump and valve on water pipe are opened, makes NaOH solution in hydraulic pump
Act on lower and atomizer and absorption cell constitutes circulation, the acidic materials in sulfur hexafluoride gas are absorbed；Absorption cell
