Description
Technical field
This utility model is related to chemical industry equipment pipeline field, more particularly to a kind of device for slowing down phosphoric acid Incrustation of pipe.
Background technology
In Wet-process Phosphoric Acid Production, easily there is scale formation in the change in phosphoric acid pipe-line system due to vacuum and temperature,
Blocking pipeline and equipment, affect the continuous and steady operation of production.Main component is the materials such as K2SiF6, Na2SiF6 in foulant,
Foulant material is closely hard, and general cleaning method is difficult to remove, and needs production to stop, and takes the mode of labor cleaning, consumes
When effort.General manufacturing enterprise can clear up once pipeline in 3-5 days, and the bad situation such as phosphorus ore quality just needs cleaning for 2 days or so
Once, the seriality and stability of production are had a strong impact on.Scale problems are solved in industry mostly using the method for addition antisludging agent,
Though the method has certain effect, need extra purchase antisludging agent, it is relatively costly, and add material subsequent production can be brought
It is certain to affect.
Utility model content
The purpose of this utility model is to provide a kind of device for slowing down phosphoric acid Incrustation of pipe, uses common in factory
Low-pressure steam, heating and thermal insulation is carried out to phosphoric acid excessively stream pipeline, reduces the temperature drop of phosphoric acid, slows down the precipitation of scale forming matter.
To achieve these goals, this utility model is employed the following technical solutions：
A kind of device for slowing down phosphoric acid Incrustation of pipe, including controller, also including vapor-liquid mixer, vapor-liquid mixer difference
It is connected with phosphoric acid inlet ductwork, phosphoric acid export pipeline and steam access tube, steam access tube is by control valve and steam inlet
Pipeline connects, and thermometer is provided with phosphoric acid export pipeline, and thermometer is connected with controller, and controller is connected with control valve.
Steam access tube as above is located on the tube wall in vapor-liquid mixer and uniformly offers passage.
Vapor-liquid mixer as above includes mixing drum and air induction mast, the two ends of mixing drum respectively with phosphoric acid inlet ductwork
Connect with phosphoric acid export pipeline, the sidepiece of mixing drum is connected with air induction mast, and steam access tube one end connects with air induction mast and extends
To mixing drum.
Advantage of the present utility model and beneficial effect are：
1st, simple structure, it is easy to use；
2nd, heating and thermal insulation is carried out to phosphoric acid, the temperature drop of phosphoric acid is reduced, slows down the precipitation of scale forming matter, prolonged at lower cost
The formation of long layer of scale；
3rd, maintenance cost is low.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- phosphoric acid inlet ductworks, 2- steam inlet pipelines, 3- control valves, 4- vapor-liquid mixers, 5- steam is passed through
Pipe, 6- thermometeies, 7- phosphoric acid export pipelines, 8- controllers, 401- mixing drums, 402- air induction masts, 501- passages.
Specific embodiment
This utility model is further described with reference to embodiment and accompanying drawing.
As shown in figure 1, a kind of device for slowing down phosphoric acid Incrustation of pipe, including controller 8, also including vapor-liquid mixer 4, vapour
Liquid mixer 4 is connected respectively with phosphoric acid inlet ductwork 1, phosphoric acid export pipeline 7 and steam access tube 5, and steam access tube 5 is by control
Valve processed 3 is connected with steam inlet pipeline 2, and thermometer 6 is provided with phosphoric acid export pipeline 7, and thermometer 6 is connected with controller 8,
Controller 8 is connected with control valve 3.
Preferably, steam access tube 5 is located on the tube wall in vapor-liquid mixer and uniformly offers passage 501.
Preferably, vapor-liquid mixer 4 includes mixing drum 401 and air induction mast 402, the two ends of mixing drum 401 respectively with phosphoric acid
Inlet ductwork 1 and phosphoric acid export pipeline 7 connect, and the sidepiece of mixing drum 401 is connected with air induction mast 402, the one end of steam access tube 5 with
Air induction mast 402 is connected and extended in mixing drum 401.
Steam inlet pipeline 2, phosphoric acid inlet ductwork 1, phosphoric acid export pipeline 7, vapor-liquid mixer 4, thermometer 6 and control valve
Connected by flange between door, it is convenient to dismantle and install.Outside steam inlet pipeline 2, phosphoric acid inlet ductwork 1 and phosphoric acid export pipeline 7
Do the anti-scald process of insulation in portion.Cross in steam inlet pipeline 2 and phosphoric acid inlet ductwork 1 and vapor-liquid mixer 4.Because steam has one
Fixed temperature and pressure, so perforate is needed on the steam access tube 5 in vapor-liquid mixer 4, to reduce vibration.
When in use, phosphoric acid enters vapor-liquid mixer 4 to this device by phosphoric acid inlet ductwork 1.Steam is by steam inlet pipe
Road 2 enters vapor-liquid mixer 4, carries out uniformly, carrying out phosphoric acid by the passage 501 of steam access tube 5 in vapor-liquid mixer 4
Heating.Phosphoric acid after heating continues to be conveyed in phosphoric acid export pipeline 7, and thermometer 6 is measured to the temperature of phosphoric acid.Can lead to
This device is crossed by the temperature control of phosphoric acid in design temperature scope（60-90℃）It is interior, if the phosphoric acid Temperature of the measurement of thermometer 6 is low
In the minima of design temperature scope, then big control valve 3 can be opened or opened by controller 8, if the measurement of thermometer 6
Phosphoric acid Temperature then can be closed by controller 8 or open little control valve 3 higher than the maximum of control design temperature scope, until
Phosphoric acid Temperature is controlled in the range of design temperature.
After installing this device, past 3 days was accomplished by clearing up pipeline once, and 12-15 talent may require that cleaning once.This
Plant failure rate is low, simple to operate, and operating cost is low.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
Category those skilled in the art can make various modifications to described specific embodiment or supplement or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
