Abstract
The utility model discloses a kind of insulation acid delivering pipeline with warning device, belong to technical field of chemical, to solve the problems, such as the uniform insulation and inner tube leakage monitoring in sulfuric acid pipeline transportation.Device includes inner and outer tubes, and one end of outer tube is provided with water inlet pipe, and the other end of outer tube is provided with outlet pipe, and outlet pipe is provided with pH detectors, warning device is connected with pH detectors.The utility model is incubated using warm water, and the heating device Inlet and outlet water mouth of pipe sets control valve, convenient to control water temperature, due to the uniform insulation effect that pipeline wraps up entirely, can effectively be protected acid delivering pipeline passivating film, be reduced corrosive pipeline, save enterprise's production cost；Heating device effluent pipe mouth sets pH detectors and alarm, is monitored early warning to backwater pH value situation of change in heating device at any time, finds leakage in time, potential safety hazard is preferably minimized；Device infusion of financial resources is few, convenient for installation and maintenance, simple operation in operation.
Description
Technical field
The utility model belongs to technical field of chemical, and in particular to a kind of insulation acid delivering pipeline with warning device.
Background technology
Sulfuric acid, due to factors such as fed distance and freight volumes, uses cast iron and carbon steel piping more during production and transport
Conveying, industrial production sulfuric acid concentration are generally 93% concentrated sulfuric acid, 98% concentrated sulfuric acid and 105% fuming acid, are less than 40 DEG C in temperature
When can make acid delivering pipeline inner surface formed one layer of passivating film, prevent sulfuric acid from further corroding pipeline.
Pipe insulation is industrially carried out by the way of pipeline tracing at present, typically uses steam tracing and electric tracing,
Steam tracing refers to a steam pipe arranged side by side by acid delivering pipeline, come temperature loss caused by compensating environment, sufficient in steam
Smelting industry, generally use steam tracing, but due to steamtraced piping and acid delivering pipeline and column distribution, cause acid delivering pipeline
Uneven heating, passivating film are destroyed, pipeline severe local corrosion, and the sulfuric acid pipeline of insulation in production is often largely occurring
Just found after leakage, then change pipeline, cause waste and potential safety hazard；Electric tracing is to use heat tracing mode of the electric energy for thermal source,
Input is high, it is necessary to which extra power consumption, does not meet proposal of the country on recycling economy.
Utility model content
The purpose of this utility model is to provide a kind of insulation acid delivering pipeline with warning device, to solve sulfuric acid pipeline fortune
The problem of uniform insulation and inner tube leakage in defeated monitor.
In order to solve problem above, technical solutions of the utility model are：
A kind of insulation acid delivering pipeline with warning device, including inner and outer tubes, one end of outer tube are provided with water inlet pipe, outer tube
The other end be provided with outlet pipe, outlet pipe is provided with pH detectors, warning device is connected with pH detectors.
Further, water inlet pipe is provided with water intaking valve.
Further, outlet valve is provided between outlet pipe and pH detectors.
The utility model or have the beneficial effect that：The utility model is incubated using warm water, the heating device Inlet and outlet water mouth of pipe
Control valve is set, it is convenient to control water temperature, due to the uniform insulation effect that pipeline wraps up entirely, effectively acid delivering pipeline can be protected to be passivated
Film, corrosive pipeline is reduced, save enterprise's production cost；Heating device effluent pipe mouth sets pH detectors and alarm, right at any time
Backwater pH value situation of change is monitored early warning in heating device, finds leakage in time, potential safety hazard is preferably minimized；Device is thrown
It is few to enter fund, convenient for installation and maintenance, simple operation in operation.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the insulation acid delivering pipeline with warning device.
Reference is as follows：1st, inner tube；2nd, outer tube；3rd, water inlet pipe；4th, outlet pipe；5th, pH detectors；6th, warning device；7、
Water intaking valve；8th, outlet valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of insulation acid delivering pipeline with warning device as shown in Figure 1, including inner tube 1 and outer tube 2, one end of outer tube 2 are set
There is water inlet pipe 3, water inlet pipe 3 is provided with water intaking valve 7, and the other end of outer tube 2 is provided with outlet pipe 4, and outlet pipe 4 is provided with pH detectors
Warning device 6 is connected with 5, pH detectors 5, outlet valve 8 is provided between outlet pipe 4 and pH detectors 5.
Before operation, water intaking valve 7 is opened, heat tracing stream of warm water of the circulating backwater of heat exchanger as sulfuric acid pipeline in front-end process
Enter water inlet pipe 3, flow against sulfuric acid conveying direction in outer tube 2, flowed out through outlet valve 8 from outlet pipe 4, after preheating five minutes,
Start to convey sulfuric acid.
During operation, sulfuric acid passes through in inner tube 1, and side het water controls water by regulating water inlet valve 7 and outlet valve 8 in outer tube 2
Temperature in the range of 35 DEG C~40 DEG C, pH detectors in 1 No leakage of inner tube, the side het water pH of display in the range of 5.5~6,
The maintains normal condition of alarm 6, when inner tube 1 leaks, heat tracing coolant-temperature gage raises in outer tube 2, and pH diminishes, the inspection of pH detectors
When measuring side het water pH less than 5.5, alarm 6 starts to alarm, and stops operation in time, is overhauled, and potential safety hazard is dropped to most
It is low.
