Description

Hot process for calcium smelting steam jet vacuum equipment

The utility model relates to a kind of industry refining calcium equipment, especially a kind of vaccum-pumping equipment that adopts thermal reduction refining calcium.

At present with regard to world wide, the smelting process of calcium metal is divided into electrolysis method and Re Fa two big classes, electrolysis method is a conventional method, hot method is the refining calcium method that grows up after electrolysis method, the metal that hot process for calcium smelting produced is more than electrolysis method, production at China's calcium metal then is to have comparative advantage with electrolysis method, and this is because domestic existing vacuum equipment is difficult to satisfy due to the process engineering of hot process for calcium smelting requires.Needing to keep absolute pressure in the hot process for calcium smelting process is 0.5-5Pa, vacuum condition like this, all select oil-sealed rotary pump associating unit to realize now, in the middle of long-term the use, find that mechanical pump has following shortcoming: because it is higher and contain a certain amount of coercibility water vapor when taking out in advance to be taken out in the medium dust loading, after dust and water vapor enter the pump housing with air-flow, cause Vacuum Mechanical Pump Oil emulsification on the one hand, cause pump housing inner rotatable part to scratch wearing and tearing on the other hand, thereby cause the oil-sealed rotary pump unstable properties, life-span is short, the maintenance cost height.

The purpose of this utility model provides the special-purpose steam jet vacuum equipment of a kind of hot process for calcium smelting, and this equipment no-rotary part need not to lubricate, stable performance, and maintenance cost is low, long service life.

The technical solution of the utility model is: a kind of hot process for calcium smelting steam jet vacuum equipment, comprise by nozzle, suck the ejector that mixing chamber and Diffuser constitute, condenser, silencing apparatus, piping attachment and seal tank, the suction port of first order ejector connects with the exhaust tube of refining calcium reactor, second, three, the suction port of level Four ejector is first with its upper level respectively, two, three grades extrusion mouth links, the extrusion mouth of fourth stage ejector enters the bottom of I intercondenser, the outlet on the suction port of level V ejector and I intercondenser top links, the extrusion mouth of level V ejector enters the bottom of II intercondenser, the top outlet of the suction port of the 6th grade of ejector and the condenser of II inter-stage links, the outlet of the 6th grade of ejector enters atmosphere by silencing apparatus, I, the II condenser, the top that reaches silencing apparatus links with circulating cooling water pipe respectively, and the drain opening of bottom inserts in the seal tank of its lower end.

Above-mentioned nozzle entrance cone angle K ₁Be 20 °-50 °, throat diameter is φ 0.9-φ 18, outlet cone angle K ₂For: 15 °-20 °, the inlet cone angle K of Diffuser ₃Be 4.5 °-8 °, throat diameter is φ 9-φ 315, outlet cone angle K ₄It is 6 °-12 °.

Cooling water inlet and gas outlet are arranged at the top of above-mentioned condenser, and gas access and coolant outlet are arranged at the bottom, and there is flow distribution plate inside.

Nozzle suction port and steam tube that device is penetrated in above-mentioned introduction at different levels link.

Enforcement of the present utility model can produce following advantage:

1, the steam jet vacuum equipment is simple in structure, low cost of manufacture, can save great amount of investment, dust-containing airflow and water vapor can not produce harm to the pump housing after entering the pump housing in the middle of the equipment operation, no any rotatable parts need not lubricate in the pump housing, need not keep in repair substantially, can reduce maintenance cost and equipment operation expense greatly, simultaneously prolonged life of equipment at double.

2, owing to adopt six grades of injections to vacuumize structure, so the speed of finding time is bigger than mechanical pump, the operation cycle is short, and the calcium crystalline state is good, and output and quality are more stable, and can be according to the production scale flexible design.

3, the steam of the waste heat flue gas production in the utilizable calcium smelting process comes the normal operation of holding pump, saves the electricity charge and cost of production greatly, has energy-conservation and the environmental protection double benefit.
