Problems solved by technology

[0002] Existing reactors generally use built-in heating elements or infrared electric heating devices installed in the middle and lower parts. For medium-sized and large-scale reactors, due to their large volume, heating is uneven, the internal temperature difference is large, and the energy utilization rate is low.
For the processes involving gas-solid reaction and gas-liquid reaction, gas inflation and pressurization are generally used to improve the gas utilization rate and reaction rate. Only under high pressure can there be high solubility, resulting in small gas-liquid and gas-solid contact area and low reaction efficiency
Reactors generally have problems such as uneven discharge, large amount of residual material, and easy blockage, which seriously affect the production efficiency of the reactor.

Embodiment 1

[0015] A 50L uniformly aerated double-layer glass reactor was used as the reaction vessel for the iron removal experiment of the zinc sulfate leaching solution. The zinc sulfate leaching solution contains 11.2g / L of ferrous iron, and the leaching solution is sprayed into the reactor from the feed port, and the inflatable disc is 1m 3 The rate of / h is evenly aerated, and at the same time, the neutralizing agent sodium carbonate is added at a certain speed to ensure that the pH of the solution in the reactor is maintained at 2-3, and the reaction temperature is 80-90°C. After the reaction is over, open the discharge valve, discharge the feed liquid under the gas pressure in the kettle, and obtain the purified iron removal liquid and iron slag after filtration.

Embodiment 2

[0019] A 50L evenly aerated double-layer glass reactor was used as the experimental reaction vessel for the iron removal experiment of the nickel sulfate leaching solution. The nickel sulfate leaching solution contains 15.25g / L of ferrous iron, and the leaching solution is sprayed into the reactor from the feed port, and the inflatable plate is 1m 3 The rate of / h is evenly aerated, and at the same time, the neutralizing agent sodium carbonate is added at a certain speed to ensure that the pH of the solution in the reactor is maintained at 2-3, and the reaction temperature is 80-90°C. After the reaction is over, open the discharge valve, discharge the feed liquid under the gas pressure in the kettle, and obtain the purified iron removal liquid and iron slag after filtration.

Abstract

The invention discloses a uniform aerating double-layered glass reaction kettle. The uniform aerating double-layered glass reaction kettle comprises a reaction kettle main body, a stirring paddle and a baiting valve, wherein the reaction kettle main body is an aerating double-layered glass reaction kettle (10) made of GG17 high borosilicate glass; an aerating plate is arranged at the bottom of the reaction kettle main body; and the stirring paddle is a double-layered stirring paddle (5). The technical method of the uniform aerating double-layered glass reaction kettle is simple and convenient to operate, can quickly and efficiently utilize the heating energy, and sufficiently utilizes the gas utilization rate.
