| titleOfInvention | Device for preparing sodium gold sulfite solution |
| abstract | The utility model relates to a device for preparing a sodium gold sulfite solution; wherein, a water adding valve, a hydrochloric acid valve, a nitric acid valve, an alkaline liquor valve, a liquid level meter, a pH meter, an exhaust valve, a hot water return valve, a discharge valve, a feed inlet, a stirrer and a hot water inlet valve are arranged on a kettle body of the gold liquid preparation system I; a feeding valve, a sodium acid valve, an alkali liquor valve, a pH meter, an exhaust valve, a hot water return valve, a discharge valve, an observation port, a stirrer and a hot water inlet valve are arranged on a double-kettle main body of the sodium gold sulfite preparation system; the second kettle feed valve is connected with the first kettle discharge valve, the second kettle hot water inlet valve is communicated with the first kettle hot water inlet valve, and the second kettle hot water return valve is communicated with the first kettle hot water return valve; the exhaust valve of the secondary kettle is communicated with the flue gas absorption tower; the water outlet valve of the heater is respectively communicated with the first kettle hot water inlet valve and the second kettle hot water inlet valve; the return valve of the heater is respectively communicated with the hot water return valve of the first kettle and the hot water return valve of the second kettle; the unstable operation factors of operators are eliminated when the sodium gold sulfite solution is prepared, and the accuracy of the concentration of the sodium gold sulfite solution is ensured. |
