Description
Technical field
The utility model relates to a kind of equipment of producing calcium oxide, especially relates to a kind of equipment of producing calcium oxide with calcium sulfate.
Background technology
Calcium oxide can be widely used in making calcium carbide, soda ash, chlorinated lime etc., also can be used as material of construction, refractory materials, siccative and soil improvement agent and calcareous fertilisers, or is used as the fusing assistant of analytical reagent, manufacturing fluorescent material, or is used for process hides, purification of waste water etc.During as material of construction and metallurgical fusing assistant, being the main raw material of hydrogen manufacturing calcium oxide and various calcium cpds, is the cheap alkali in the chemical industry.
Traditional calcium oxide production mainly is to be raw material with the Wingdale, to calcine in Wingdale and solid fuel mixes or layering is packed into the shaft furnace, the defective of its existence is that production process is easily introduced secondary impurities, and product purity is low, in addition, rate of decomposition is desirable not enough.
The utility model content
Technical problem to be solved in the utility model is provide a kind of rate of decomposition that improves, and no secondary impurities to be introduced in the production process, the equipment with calcium sulfate production calcium oxide that product purity is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of equipment of producing calcium oxide with calcium sulfate, comprise hopper, the high-temperature calcination kiln, well heater, the gas boosting pump, cuvette, described well heater is installed on the outside of high-temperature calcination kiln, the top of described high-temperature calcination kiln is provided with vaccum exhaust outlet, described vaccum exhaust outlet links to each other with an end of gas boosting pump by pipeline, the other end of described gas boosting pump links to each other with cuvette by pipeline, also be provided with the pressurization gas-solid injector, ultrasonic generator, single screw extrusion machine, the opening for feed of described pressurization gas-solid injector links to each other with hopper, discharge port links to each other with the opening for feed of high-temperature calcination kiln, described ultrasonic generator is installed on the outside of well heater, described single screw extrusion machine links to each other with the discharge port of high-temperature calcination kiln, and the end of described single screw extrusion machine is provided with discharge opening.
Further, be loaded with alkali lye in the described cuvette.
Working process: calcium sulphate powders is dropped into hopper, calcium sulfate enters the pressurization gas-solid injector by hopper, under the effect of pressurization gas-solid injector, spray in the high-temperature calcination kiln that is warming up to 1000-2000 ℃, in the high-temperature calcination kiln, calcium sulfate generation decomposition reaction, start ultrasonic generator simultaneously, in the high-temperature calcination kiln, produce the 20-30kHz ultrasonic wave field, calcium sulphate powders rate of decomposition under the ultrasonic wave field effect is accelerated, waste gas after reaction generates pumps into cuvette by the gas boosting pump, and is absorbed by alkali lye, and the calcium oxide of generation is delivered to discharge opening by screw extrusion press and discharges.
The purpose that the utility model arranges the pressurization gas-solid injector is calcium sulphate powders to be disperseed better, better thermally equivalent.And the purpose that ultrasonic generator is set is, utilize ultrasonic wave can impel the dispersion of calcium sulphate powders on the one hand, accelerate heat distribution, promote the decomposition of calcium sulphate powders, can transmit the energy that ultrasonic generator produces on the other hand, be passed to calcium sulfate molecule aspect and excite the mechanical vibration of calcium sulphate powders solid particulate interior molecules aspect, improve material temperature (ultrasonic wave is a kind of elastic mechanical ripple in the material medium, and it has machinery, energy double effect to material).
Compared with prior art, the utility model can make the calcium sulfate rate of decomposition accelerate, and to promote the decomposition of calcium sulphate powders, simultaneously, products obtained therefrom purity can reach more than the 85wt%.
