Abstract

The invention discloses a concentrated acid leaching reactor. By means of the concentrated acid leaching reactor, the problems that in the prior art, equipment is corroded by high-concentration acid mist generated in the reaction process of concentrated acid and slurry, and health of operating personnel is harmed are solved. The concentrated acid leaching reactor comprises a reaction barrel body, a hydraulic lifting device, an acid mist collecting body and a waste gas collecting device. The hydraulic lifting device comprises a hydraulic station and a hydraulic rod connected with the hydraulic station. The acid mist collecting body comprises an acid mist collecting opening, a slurry inlet, a spigot and faucet pipe and a concentrated acid inlet. The waste gas collecting device surrounds the outer side of the reaction barrel body. The top of the waste gas collecting device is provided with a waste gas collecting opening. The waste gas collecting device communicates with the reaction barrel body through a gas phase escaping opening formed in the top of the side wall. The bottom of the reaction barrel body is provided with a discharge outlet. According to the concentrated acid leaching reactor, waste gas, the acid mist and water vapor which are generated in the reaction process of the slurry and the concentrated acid can be collected and recycled for acid making or discharged after being treated and reaching the standard, so that the leakage rate of the waste gas and the acid mist is greatly decreased, the corrosion degree to the concentrated acid leaching reactor is lowered, and the safety of the operating personnel is protected.

Description

technical field [0001] The invention belongs to the technical field of refractory metal extraction, and relates to a concentrated acid leaching reactor. Background technique [0002] In the leaching process, the high leaching effect of concentrated acid is often used to leach the pulped material. During the reaction, the concentrated acid can convert the metal ions in the material into soluble sulfates, accompanied by a large amount of waste gas and heat. released, but the water content of the reacted material is low, and it is easy to agglomerate, which is easy to cause equipment blockage. [0003] At the same time, due to the high concentration of acid mist (SO 3 , nitrogen oxides, HCL gas), which is highly corrosive to the equipment and also endangers the health and safety of the operators. Generally, such equipment is constructed in the open air and isolated from personnel, but the operation of the equipment cannot be grasped in time because the operators are not on sit...
