Abstract
The utility model provides a concentrated sulfuric storage tank with an anodic protection device, and relates to a container for storage of corrosive liquid-state materials. The concentrated sulfuric storage tank comprises a tank body, a jacket, a feeding port, a discharging port, a water inlet, a water outlet, a water draining port, an anodic protection control instrument, a cathode and a reference electrode; and the concentrated sulfuric storage tank can apply anodic protection on carbon steel, stainless steel and multiple alloys by using the activation-passivation transition characteristics of the carbon steel, stainless steel and multiple alloys in concentrated sulfuric acid, so that the carbon steel, stainless steel and multiple alloys are at a stable passivation state since the carbon steel, stainless steel and multiple alloys in concentrated sulfuric acid has activation-passivation transition characteristics, the concentrated sulfuric storage tank can enable the carbon steel, stainless steel and multiple alloys to be in a stable passivation state by applying anodic protection, and the corrosion rate of the carbon steel, stainless steel and multiple alloys is greatly reduced, thus ensuring that the construction period of a concentrated sulfuric tank is short in industrial application, the service life of the concentrated sulfuric tank is long, and the concentrated sulfuric tank is easy to maintain, safe and reliable.
Description
Technical field
The utility model relates to the container of the liquid storing material of corrodibility, is specifically related to a kind of vitriol oil storage tank.
Background technology
vitriol oil tank is used by industrial chemical industry, not only sulfuric acid manufacturing concern needs vitriol oil tank, the sulfuric acid applying unit also need be equipped with vitriol oil tank, vitriol oil tank comprises vitriol oil circulation tank and vitriol oil storage tank, severe corrosive due to the vitriol oil, vitriol oil storage tank is carbon steel structure, the vitriol oil should cool the temperature to normal temperature through the finished acid water cooler before entering storage tank, because vitriol oil flask volume is large, diameter can reach 20 meters, height can reach 15 meters, the system that there is no the finished acid water cooler, vitriol oil Tank cognition is corroded, affect work-ing life, breakdown might occur leak acid, cause casualties.
The existing equipment of using anodic protection of prior art, as concentrated sulfuric acid cooler, acid trap and vitriol oil pipeline, the size of these equipment is less, and the design of cathod system is mostly estimated according to anodic protection experimental data and use experience; Yet vitriol oil tank size is large, and the negative electrode decoration form that only depends on estimation to obtain can increase cost or cause protecting poor effect.
Summary of the invention
The purpose of this utility model is to provide a kind of being easy to safeguard, the safe and reliable vitriol oil storage tank that anode protection device is set.
The technical solution of the utility model is:
The vitriol oil storage tank of anode protection device is set, comprise tank body, chuck, opening for feed, discharge port, water-in, water outlet, water port and anodic protection controller, negative electrode, reference electrode, wherein, described tank body is made by carbon steel, stainless steel, carbon steel one stainless steel composite material or alloy material; The outside of described tank alms bowl arranges described chuck, and the top of described tank body arranges opening for feed, and the bottom arranges discharge port, and the lower side of described chuck arranges water-in, water port, and the upper lateral part of described chuck has water outlet; The contact surface of tank body and the vitriol oil is anode; The negative electrode that plays the On current effect is arranged in tank body, and described negative electrode adopts graphite, lead, and stainless steel or alloy material are made, and reference electrode is arranged in tank body, anodic protection controller and anode, negative electrode and reference electrode are connected respectively.
Described reference electrode is 3～12, evacuates the different positions that is arranged on tank body;
Described negative electrode is 2～20, and parallel equidistant is arranged in the tank body axis direction.
The beneficial effects of the utility model are: the vitriol oil storage tank that anode protection device is set utilizes carbon steel, stainless steel and multiple alloy to have the activation passive behavior in the vitriol oil; after it is applied anodic protection; can make it be in stable passive state; corrosion rate in the vitriol oil reduces greatly, thereby guarantees concentrated sulfuric acid groove short construction period, long service life in industrial application, is easy to safeguard, safe and reliable.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
In conjunction with Fig. 1, the vitriol oil storage tank of anode protection device is set, comprise tank body 1, chuck 2, opening for feed 3, discharge port 4, water-in 5, water outlet 6, water port 7 and anodic protection controller 8, negative electrode 9, reference electrode 10, wherein, described tank body 1 is made by carbon steel, stainless steel, carbon steel one stainless steel composite material or alloy material; The outside of described tank alms bowl 1 arranges described chuck 2, and the top of described tank body 1 arranges opening for feed 3, and the bottom arranges discharge port 4, and the lower side of described chuck 1 arranges water-in 5, water port 6, and the upper lateral part of described chuck 2 has water outlet 6; Tank body 1 is anode with the contact surface of the vitriol oil; The negative electrode 9 that plays the On current effect is arranged in tank body 1, and described negative electrode 9 adopts graphite, lead, and stainless steel or alloy material are made, and reference electrode 10 is arranged in tank body, anodic protection controller 8 and anode, negative electrode 9 and reference electrode 10 are connected respectively.
Described reference electrode 10 is 3～12, evacuates the different positions that is arranged on tank body 1;
Described negative electrode 9 is 2～20, and parallel equidistant is arranged in tank body 1 axis direction.
When practice is used, the vitriol oil is through unloading sour pump 9 from 8 dozens of acid tank trucks of fortune to vitriol oil opening for feed 3, and open the bad water water intaking valve 12 of condensation this moment, and bad water of condensation enters chuck 2 through the water-in 5 of chuck 2 lower sides, open the bad water outlet valve 13 of condensation, bad water of condensation flows through chuck 2 to the heating of vitriol oil tank again.During complex acid, open baiting valve 10, the vitriol oil flows out through discharge port 4, pumps to configure rare sulphur by Countermeasure of Concentrated Acid Pump 11 and makes.After the vitriol oil discharges, close the bad water water intaking valve 12 of condensation, the bad water outlet valve 13 of condensation is opened water discharge valve 14, and the water in chuck 2 is drained.
