Description

A sulfuric acid pump 11 and a sulfuric acid check valve 12 are arranged on the connecting pipeline between the steel slag fluorine and chlorine extractor 2 and the sulfuric acid solution storage 10. The top of the steel slag fluorine and chlorine extractor 2 is connected to a funnel-shaped steel slag sample feed pipe 13. A feed valve 14 is arranged on the steel slag sample feed pipe 13. The steel slag fluorine and chlorine extractor 2 is divided into two parts on both sides of the lower part of the steel slag fluorine and chlorine extractor 2. A temperature sensor 15 is separately provided. The top of the steel slag fluorine and chlorine extractor 2 is connected to the top of the condenser 16 through a pipeline. A serpentine heat exchange tube 17 is provided in the condenser 16. The bottom end of the heat exchange tube 17 is connected to the outlet of the cooling circulating water machine 18 through a pipeline. The top of the heat exchange tube 17 is connected to the return water port of the cooling circulating water machine 18 through a pipeline. The bottom of the condenser 16 is connected to the top of the liquid outlet pipe 19. The bottom end of the liquid outlet pipe 19 is connected to one end of the hose 20. The other end of the hose 20 is connected to the connection The top of the tube 21 is connected, the bottom end of the connecting tube 21 is connected to the top of the receiver 22, the bottom of the receiver 22 is connected to the liquid outlet pipe 23, the liquid outlet pipe 23 is provided with a liquid outlet valve 24, a funnel-shaped addition pipe 25 is provided on the top of the receiver 22, and an addition valve 26 is provided on the addition pipe 25. A fixing plate 27 is respectively provided on both sides of the middle part of the receiver 22, the fixing plate 27 is fixedly connected to the top of the weighing sensor 28, and the bottom end of the weighing sensor 28 is fixedly connected to the top of the bracket 29.When the present invention is used, deionized water is added to the steam generator 1 by turning on the water pump 6 and the water adding solenoid valve 7. At the same time, the first liquid level sensor 9 in the steam generator 1 can obtain the liquid level position in the steam generator 1 in real time. When the liquid level reaches the specified height range, the water pump 6 and the water adding solenoid valve 7 are turned off. Since the deionized water is used, there is no need to clean the remaining water in the steam generator 1 after one operation is completed, and the water can be continued to be used in the next operation, thereby realizing full utilization of resources. When the steam generator 1 is filled with water, the ground steel slag powder is accurately weighed and then passed through the steel After the slag sample is fed into the steel slag fluorine and chlorine extractor 2 through the feed pipe 13, the feed valve 14 is closed, and then the sulfuric acid pump 11 is turned on to obtain the liquid level position in the steel slag fluorine and chlorine extractor 2 in real time through the first liquid level sensor 9 in the steel slag fluorine and chlorine extractor 2. When the liquid level reaches a specified liquid level height range, the sulfuric acid pump 11 is turned off, and at the same time, a specified amount of sodium hydroxide solution is added to the receiver 22 through the addition pipe 25, and then the addition valve 26 is closed. After the solution sample in the steam generator 1, the steel slag fluorine and chlorine extractor 2 and the receiver 22 is added, the electric heating plate 8 is turned on to heat the steam generator 1. The deionized water in the slag fluorine and chlorine extractor 2 is heated to generate steam, which enters the solid-liquid mixture of the slag powder and the sulfuric acid solution in the slag fluorine and chlorine extractor 2 through the steam pipe 3 to be heated, and the temperature in the slag fluorine and chlorine extractor 2 is monitored in real time by the temperature sensor 15, and the power of the electric heating plate 8 is controlled according to the obtained temperature to ensure that the temperature in the slag fluorine and chlorine extractor 2 is within the specified range. The water vapor that may contain fluorine and chlorine in the slag fluorine and chlorine extractor 2 is condensed and liquefied by the condenser 16 and then sent to the receiver 22. The weighing sensor 28 accurately weighs the amount of water in the receiver 22. The weight changes. When the specified weight is reached, the electric heating plate 8 is turned off. After the steam flow is finished, the cooling circulating water machine 18 is turned off. The solution in the receiver 22 is allowed to flow out along the liquid outlet pipe 23 by opening the liquid outlet valve 24 and then sent into the volumetric flask for fixed volume and sampling and detection. At the same time, the receiver 22 can be rinsed several times with deionized water added through the addition tube 25 to ensure that there is no fluorine and chlorine residue to avoid affecting the subsequent test results. At the same time, since deionized water is also added when fixing the volume, the receiver 22 can be cleaned and used again, and the residual deionized water will not affect the subsequent detection.

[0020] Specifically, the bottom of the steel slag fluorine and chlorine extractor 2 of this embodiment is provided with an oscillator 30. The present invention can make the sulfuric acid solution fully contact with the steel slag powder through the oscillator 30, thereby ensuring the fluorine and chlorine extraction efficiency and the accuracy of the detection result.

The present invention opens the discharge pump 38 and the discharge valve 39 to send the mixture of steel slag powder and sulfuric acid solution after the operation is completed into the waste liquid recovery bucket through the discharge pipe 37, thereby conveniently completing the waste liquid recovery.

[0026] Furthermore, the water pump 6 described in this embodiment is connected to the top of the steel slag fluorine and chlorine extractor 2 through a pipeline, and a cleaning valve 40 is provided on the connecting pipeline between the water pump 6 and the steel slag fluorine and chlorine extractor 2. The present invention adds deionized water to the steel slag fluorine and chlorine extractor 2 for cleaning by opening the water pump 6 and the cleaning valve 40 to remove the solid-liquid mixture of the steel slag powder and the sulfuric acid solution. At the same time, the oscillator 30 can be turned on during the cleaning process to ensure that there will be no residue. After cleaning, the waste water is sent to the waste liquid recovery barrel by opening the discharge pump 38 and the discharge valve 39 and the discharge pipe 37. After several cleanings, it is ensured that there is no residue. At the same time, the deionized water will not affect the subsequent detection operation, and no drying is required. The operation is simple and the detection result can be ensured to be accurate.

[0027] Furthermore, the receiver 22 of this embodiment is provided with a polytetrafluoroethylene lining 41. The polytetrafluoroethylene lining 41 of the present invention is corrosion-resistant and has a low surface tension, so that the solution will not adhere to the wall, thereby ensuring that the liquid to be tested is completely discharged and the accuracy of the test result is ensured.
