Reactor flue gas pressure-relief treatment device in titanium sponge production process

Abstract

The invention discloses a reactor flue gas pressure-relief treatment device in a titanium sponge production process, which mainly comprises a reactor and a pressure relief tube on a reactor large cover, wherein a vacuum rubber plug is arranged at the top end of the pressure relief tube, the pressure relief tube is connected to a buffer tank through a pipeline, a ball valve and a one-way valve aresequentially arranged on the pipeline, and the buffer tank, an acid seal tank, a leaching tower and a chimney are sequentially connected; a pressure relief area is arranged in the acid seal tank; upper and lower areas of an acid seal area are arranged in the acid seal tank and are in communication through a flow guide tube; the lower end of the flow guide tube is inserted into acid sealing liquidat the lower part of the acid seal area, and the position of a gas inlet in the acid seal tank is higher than the liquid level of the acid sealing liquid. The device can be utilized to realize automatic pressure relief of pressure in the reactor and flue gas collecting treatment, so that disordered discharge is avoided, production environment quality is improved, and labor intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of titanium sponge production, and in particular relates to a reactor flue gas pressure relief treatment device in the production process of titanium sponge. Background technique [0002] At present, the industrial production of sponge titanium mainly adopts the magnesium reduction titanium tetrachloride method. The production process is to continuously feed titanium tetrachloride into the closed reactor to react with liquid magnesium to form sponge titanium and magnesium chloride. Due to the specific gravity of the magnesium chloride liquid produced by the reaction is greater than liquid magnesium, so it settles to the bottom of the reactor. As the reduction reaction continues, the liquid magnesium level in the reactor rises continuously, and the pressure in the reactor will also gradually increase. In order to avoid overpressure in the reactor, the During the reduction production process, it is necessary t...

[0002] At present, the industrial production of sponge titanium mainly adopts the magnesium reduction titanium tetrachloride method. The production process is to continuously feed titanium tetrachloride into the closed reactor to react with liquid magnesium to form sponge titanium and magnesium chloride. Due to the specific gravity of the magnesium chloride liquid produced by the reaction is greater than liquid magnesium, so it settles to the bottom of the reactor. As the reduction reaction continues, the liquid magnesium level in the reactor rises continuously, and the pressure in the reactor will also gradually increase. In order to avoid overpressure in the reactor, the During the reduction production process, it is necessary to relieve the pressure of the reactor from time to time. In the prior art, a pressure relief pipe is usually provided on the large cover of the reactor, and the outlet is blocked with a silicone rubber plug. Remove the plug and release the pressure of the reactor. During the process of pressure relief, a large amount of flue gas will be discharged from the reactor. The main components of the flue gas include low-valent chlorides, titanium tetrachloride, etc. Attached to the lifting equipment of the factory building, it is easy to cause corrosion to the equipment and the production site, and seriously affects the production environment
