Embodiment 1

[0053] A reactor pressure stabilization control device, comprising an air inlet pipeline 2, an air chamber 11, a PLC controller 8 and a driving device 9, the air chamber 11 is provided with an air inlet 12, and the air inlet 12 is connected to the air inlet pipe 2, the driving device 9 is connected with a thimble 4, and the thimble 4 cooperates with the air inlet 12, and the air inlet pipe 2 is provided with a first pressure sensor 7, and the first pressure sensor 7 is connected with the PLC controller 8 is connected, the PLC controller 8 is connected with the driving device 9, and the air chamber 11 is also provided with an air outlet 13, and the air outlet 13 is communicated with the exhaust pipe 5, and the PLC controller 8 is externally connected with a main console, The PLC controller 8 is connected to the main console through WIFI signals. When the reactor starts feeding, the main console sends instructions to the pressure stabilization control device through WIFI, and the...

Embodiment 2

[0069] Embodiment two: the length of the tapered bus bar at the end of the thimble is 40mm, and the length of the conical surface of the air inlet 12 is 20mm. The inner wall surface of the thimble is set as a conical surface capable of forming a sealing surface with the outer wall surface of the thimble 4. Preferably, the length of the sealing surface along the direction of the generatrix of the conical surface is 20mm, which is not easy to cause sticking of the sealing surface, and the sealing effect is better. In addition, The corners at the end of the conical surface of the air inlet 12 are rounded, and the angle of the lower section of the air inlet 12 is rounded to avoid possible damage to the outside of the thimble 4 when the thimble 4 is inserted into the air inlet 12 from above by using a non-rounded structure. The problem of causing damage to the wall surface and thereby breaking the seal occurs.

Embodiment 3

[0070] Embodiment three: described air outlet 13 is provided with dry dust remover 3, and dry dust remover 4 comprises porous particulate matter, and described porous particulate matter can comprise activated carbon, zeolite molecular sieve and activated alumina, and this scheme preferably activated carbon, activated carbon is to airborne Water vapor and low-priced titanium dust have a good adsorption function, which can effectively prevent the gas from being condensed and mixed with the powder when it encounters air, which will cause the blockage of the exhaust pipe.

Abstract

The invention discloses a reactor pressure stability control device and method, belongs to the technical field of metallurgical production, and solves the problems that in the process of generating titanium sponge by a magnesiothermy method, the pressure of a reactor cannot be stably controlled, the pressure is too high, the pressure relief is too fast, low-valence titanium powder blocks a pipeline, and the safety of field staff cannot be guaranteed, and stable operation and production efficiency of production are influenced. The device comprises an air chamber, an air inlet is formed in the air chamber and communicated with an air inlet pipeline, a driving device is connected with an ejector pin, the ejector pin is matched with the air inlet, a first pressure sensor is arranged in the airinlet pipeline and connected with a PLC, the PLC is connected with the driving device, the air chamber is further provided with an air outlet, and the air outlet is communicated with an exhaust pipeline. The PLC is externally connected with a main console, and the PLC is in communication connection with the main console. According to the present invention, the opening degree of the gas inlet is precisely regulated and controlled to control the pressure in the reactor so as to achieve the purpose of stable control of the pressure value required by the reactor at each production stage.

Description

technical field [0001] The invention relates to the technical field of metallurgical production, in particular to a reactor pressure stabilization control device and method during the reduction process of sponge titanium. Background technique [0002] In the process of producing sponge titanium by magnesia thermal method, a large amount of heat will be released during the reduction reaction between titanium tetrachloride and liquid magnesium. At the same time, with the acceleration of titanium tetrachloride feeding, the pressure in the reactor will remain relatively At a high level, when the pressure exceeds 25kPa, the system will open all the valves for self-protection, and the pressure will drop to 5kPa instantaneously, so there will be sharp fluctuations in pressure, which will affect the normal production. At the same time, the pressure is released quickly, and the flow rate of the gas is large, which will bring the low-priced titanium powder generated between the large ...
