Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
Embodiment 1
As shown in Figure 1, in a kind of PVC production process based on the C of acetylene
2h
3cl synthesizer, comprise mixing arrangement and reforming unit, described mixing arrangement comprises main gas inlet pipe 11, the circumference of main gas inlet pipe 11 connects the auxiliary gas inlet pipe 12 of some tapers, the wealthy mouth of each auxiliary gas inlet pipe 12 connects auxiliary gas generator, slot is connected to the sidewall of main gas inlet pipe 11, one end of main gas inlet pipe 11 connects main gas generator, the other end connects the wealthy mouth of the skirt 13 of taper, the slot of skirt 13 is connected to mixed gas storehouse 15, described reforming unit comprises bobbin carriage 26, some catalytic bed dividing plates 24 are had in bobbin carriage 23, the conversion tube device be communicated with the escape pipe 16 in mixed gas storehouse 15 is furnished with between adjacent catalytic bed dividing plate 24.
As shown in Figure 2, conversion tube device comprises a band ring pipe 21 jaggy, multiple straight tube 22 is vertically connected on ring pipe 21, and be communicated with ring pipe 21, ring pipe 21 is communicated with escape pipe 16 by gaseous mixture air inlet pipe 25 simultaneously, the breach end of wherein said ring pipe 21 is closed with plug, and the two ends of each straight tube 22 are also closed with plug, and ring pipe 21 and straight tube 22 are provided with the pore 23 being with stifled son.
According to this device, namely acetylene mixes in main gas inlet pipe 11 with HCl gas, because auxiliary gas inlet pipe 12 is pyramidal structure, therefore, pressure increase when entering, good mixed effect can be played, skirt 13 again through taper enters mixed gas storehouse 15, and pressure increases further, after entering, pressure is rapid drop again, and the repeatedly change of pressure can make mixed effect better.Afterwards, mist enters into each ring pipe 21 by escape pipe 16, is then again disperseed by straight tube 22, eventually through each pore 23 by distribution of gas between catalytic bed, make mist and catalyst can produce good contact, promote changing effect.The length of straight tube 22 can be arranged according to the distance between adjacent catalytic bed dividing plate 24, ensures packing space to greatest extent, gas uniform is distributed.Simultaneously can select open some stifled sons according to actual conditions, shed situation to adjust gas.
