Abstract
The present invention relates to material transportation field, a kind of defeated acid system of pipeline is disclosed, the defeated acid system of the pipeline includes acid delivering tube, the acid delivering tube outer layer sets muff, muff two ends set ring-type steel plate, and the ring-type steel plate is connected with acid delivering tube outer wall, and electrolyte is set between muff and acid delivering tube.The present invention solves the defeated acid system of pipeline in the prior art and cost height, the problem of insulation is difficult is incubated to acid solution, and realizes effective control to acidity, pressure, temperature in muff.
Description
Technical field
The present invention relates to liquid transporting field, relate more specifically to a kind of defeated acid system of pipeline.
Background technology
Sulfuric acid is big in some industry consumptions as a kind of industrial chemicals.For example, in Titanium White Production By Sulfuric Acid Process process
In, one ton of titanium dioxide needs consumption 3~4t concentrated sulfuric acids.So, the means of transportation of sulfuric acid will also result in the change of technique productions cost
Change.Traditional sulfuric acid long distance transportation mode has tank wagon transport, train tank car transport.Many sulfuric acid height consumption enterprises are most
All built according to sulphuric acid production enterprises, track for a train builds cost height, so more using tank wagon transport.Automobile Transportation is invested
Greatly, freight volume is small, cost is high, pipeline transportation relative inexpensiveness.But, high-concentration sulfuric acid crystallization temperature is very high, such as 98% concentrated sulfuric acid
Crystallization temperature is 1.8 DEG C, needs to maintain certain temperature in transportation.And temperature is too high can cause acid delivering pipeline passivating film
Destruction, causes sulfuric acid corrosive pipeline.So pipeline transportation process needs insulation, traditional steam insulation consumption is big, causes defeated acid
The heated inequality of pipeline, corrosion aggravation.Electric-heating belt need to continue heat tracing, and heat tracing process is uncontrolled, and energy consumption is higher.
The content of the invention
To solve the problem of defeated acid system of pipeline in the prior art is incubated cost height, insulation hardly possible to acid solution, the present invention is carried
For a kind of defeated acid system of pipeline.
The present invention is adopted the following technical scheme that：A kind of defeated acid system of pipeline, the defeated acid system of the pipeline includes acid delivering tube, described
Acid delivering tube outer layer sets muff, and muff two ends set ring-type steel plate, and the ring-type steel plate is connected with acid delivering tube outer wall, muff
Electrolyte is set between acid delivering tube.
The electrolyte external circuitses control device, the external circuitses control device includes dcs, this point
Cloth control system is connected with temperature monitor, the contact and electrolyte contacts of the temperature monitor.
The dcs is connected with pH detectors, the contact and electrolyte contacts of the pH detectors.
The contact and electrolyte contacts of pressure regulator.
The defeated acid system of pipeline of the present invention, realizes effective insulation to electrolyte, the external controller for electric consumption of electrolyte,
Realize and monitoring is realized to defeated sour process, be effectively reduced corrosive pipeline, save the energy.

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
Referring to accompanying drawing 1-2, the invention provides a kind of defeated acid system of pipeline, the defeated acid system of the pipeline includes acid delivering tube 1, institute
State the outer layer of acid delivering tube 1 and muff 2 is set, the two ends of muff 2 set ring-type steel plate 4, and the ring-type steel plate 4 and the outer wall of acid delivering tube 1 are close
Envelope connection, forms sealing space between muff 2 and acid delivering tube 1, electrolyte 3 is set between muff 2 and acid delivering tube 1, to defeated acid
Pipe 1 plays a part of effectively being incubated.Acid delivering tube 1 is ordinary carbon steel pipe, two ends welded flange 10；Muff 2 is sleeve pipe, and caliber is big
In 5~8cm of acid delivering pipeline, built-in neutral electrolyte 3, neutral electrolyte does not corrode to pipeline, and with good electric conductivity；Protect
Temperature set two ends are welded using ring-type steel plate 4 with acid delivering tube 1, realize that muff 2 is tightly connected with acid delivering tube 1, and can be to muff 2
Play a supporting role.
The perforate near the mouth of pipe of muff 2, sets electric power incoming line mouthful and line outlet, setting electrode 5 in it.The electrolyte
External circuitses control device 11, the circuit control device 11 includes electrode 5, switch 6, dcs（DCS）12, point
Cloth control system 12 is connected with the control of switch 6, dcs（DCS）12 are connected with temperature monitor 9, temperature inspection
Survey instrument 9 and stretch into the confined space that muff 2 is constituted with acid delivering tube 1, the contact of temperature monitor 9 is contacted with electrolyte 3.The opposing party
Face, dcs（DCS）12 are connected with pH monitorings meter 8, and pH monitorings meter 8 stretches into what muff 2 was constituted with acid delivering tube 1
Confined space, the contact of pH monitorings meter 8 is contacted with electrolyte 3.Pressure regulator 7 stretches into close between acid delivering tube 1 and muff 2
Close in space, the contact of pressure regulator 7 is in contact with electrolyte 3.In use, once temperature monitor 9 is detected
Temperature is less than setting value, and such as 10 DEG C, temperature monitor 9 transmits signals to DCS, and DCS controlling switches closure, control circuit connects
It is logical, the Inner electrolysis matter 3 of muff 2 is heated.When temperature is too high, temperature monitor 9 transmits signals to DCS, and DCS controls are opened
Shut-off is opened, and control circuit disconnects.The pressure value on pressure regulator 7 is observed, when pressure is higher than design load in muff 2,
It can be depressurized by pressure regulator 7.When system pH detectors 8 detect pH changes, pipeline leakage acid can be judged rapidly, to omission
Pipeline integral replacing.Overall parcel muff 2, can reduce system heat losses outside acid delivering tube line.
During pipeline construction, docked using flange, make the W-shaped trend of pipeline, landform can also be used, pipeline is kept necessarily
The gradient, easy access pipeline acid discharge.
