Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 , figure 2 As shown, the small flow UF powered by compressed air described in the present invention 6 The composition and connection relationship of the gas booster device are as follows: the connecting plate 18 is installed on the upper cover 22 through bolts 19, there are three connecting plates 18 at the bottom of the device, and the bolts 19 and the connecting plate 18 are separated by spring washers 20 to reduce vibration. Near the bottom of the loam cake 22, a forward reversing air hole 17 is drilled to lead to the driving gas side piston 4. Drive gas side piston 4 adopts flange connection with loam cake 22. Open a hole in the center of the driving gas side piston 4 and install the valve stem 5 by welding, and the two ends of the valve stem 5 are fixed to drive the gas side piston 4 and the pressurized gas si...

The invention belongs to the technical field of uranium hexafluoride gas pressurization in the nuclear industry uranium conversion industry and particularly relates to a small-flow UF6 gas pressurizer with compressed air as power. A connecting plate is mounted on an upper cap, and a forward-direction reversing air hole is drilled in the position, close to the bottom, of the upper cap and communicates to a driving gas side piston. The driving gas side piston is connected with the upper cap through a flange, a valve rod is mounted in the center of the driving gas side piston, and the two ends of the valve rod fixes the driving gas side piston and a pressurized gas side piston through nuts, spring cushions and flat gaskets. The driving gas side piston is connected with a driving compression cylinder outer cover in a threaded mode, and the driving compression cylinder outer cover is connected with an insolating cover in a threaded mode. A reverse-direction reversing air hole is drilled in the position, close to the bottom, of the insolating cover and communicates to the interior of the driving compression cylinder outer cover. A driving air inlet connector is formed in the side face of the isolating cover and communicates to the interior of the driving compression cylinder outer cover, and the top of the isolating cover is provided with a silencer. According to the small-flow UF6 gas pressurizer, the compressed air serves as the power, and the pressure of UF6 gas can be stably increased to be 0.3 MPa through compression of the pistons.
Description
technical field [0001] The invention belongs to the technical field of pressurizing uranium hexafluoride gas in the uranium conversion industry of the nuclear industry, and specifically relates to a small-flow UF powered by compressed air 6 Gas booster. Background technique [0002] In the fluorination process of uranium conversion production, UF is mainly 4 with F 2 reaction, generating UF 6 The product is in gaseous state, called furnace gas. To guarantee UF 4 with F 2 Fully reacted, an excess of F should be added 2 . But if too much join F 2 It not only wastes materials but also makes subsequent pairs residual F 2 The processing difficulty increases, is not conducive to environmental protection. By detecting F in the furnace gas 2 content, can better control F 2 The added amount can not only reduce the cost but also benefit the environment. Integrating the existing domestic technical level and ability, using chromatographic method to detect UF 6 Furnace gas ...
