Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
With reference to legend 1, one production of sodium chlorate hydrogen purification workshop section system, comprise the hydrogen water sealed tank 1 connecting successively in order, salt solution absorption tower 2, the first soda-wash tower 3, the second soda-wash tower 4, the 3rd soda-wash tower 5 and water wash column 6, one hydrogen outlet of described water wash column 6 after water sealed tank 7 by chimney 9 emptying, another hydrogen outlet of described water wash column 6 is connected with water ring compressor 11 in turn, the first water cooler 12, the first wire mesh demister 13, active carbon adsorber 14, the second wire mesh demister 15, deoxygenator 16, the second water cooler 17, under meter and hydrogen pressure station 18, the alkaline solution outlet of described water wash column 6 is connected to lye vat 10 through the 4th soda-wash tower 8.
In one embodiment, for production control flow process better, between the alkaline solution outlet of described water wash column 6 and the 4th soda-wash tower 8, be connected with lye pump and under meter.
Work operation instruction of the present utility model: from the hydrogen of potroom, its temperature is about 80 degrees Celsius, by after hydrogen water sealed tank 1, be introduced into salt solution absorption tower 2 use brine sparges cooling and washing, then successively by the first soda-wash tower 3, the second soda-wash tower 4 and the 3rd soda-wash tower 5, use sodium hydroxide solution spray washing, remove most of chlorine, finally by water wash column 6, use tap water spray washing, except lixiviating mist.The alkali lye of washing use, carries the 4th soda-wash tower 8 by lye pump, flow back into lye vat 10, continuous circulation, and lye vat 10 needs the liquid level that keeps certain, to guarantee the fluid-tight of soda-wash tower.
Through the part of the hydrogen (chlorine gas concentration is less than 100ppm) of most of chlorine of removing of washing by after water sealed tank 7 by chimney 9 emptying, another part is forced into 0.08MPa by water ring compressor 11, send into the first water cooler 12 and be cooled to normal temperature, remove vaporific water droplet through the first wire mesh demister 13, then enter active carbon adsorber 14 and further remove remaining chlorine, hydrogen out enters deoxygenator 16 after by the second wire mesh demister 15, owing to emitting heat in de-oxygen process, therefore hydrogen out will be cooled to normal temperature by rear the second water cooler 17, after dewatering, deliver to hydrogen pressure station 18 by under meter.In order to prevent deoxidation solid/liquid/gas reactions excess Temperature, the hydrogen that a part is purified compresses by water ring compressor 11, below 2%, guarantees the safety of deoxidation gas with the content of controlling hydrogen before deoxidation gas, and the oxygen level that goes out deoxidation gas requires below 0.4%.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
