Meanwhile, because the second pipe of sublimating is different from the temperature of pipe of sublimating, therefore to sublimate respectively.
Described second pipe of sublimating is parallel to each other with pipe of sublimating, and mutually vertical with the top of trapping system; Guarantee that two reactors can share one and catch level system.The material of pipe of sublimating is 316L, and diameter is 108-159mm.
The second described reactor and second is sublimated between pipe and is also provided with gas phase pipe, in the middle part of gas phase pipe, expansion joint is housed, and it is provided with heating tape with second one end that pipe is connected of sublimating.Because the second reactor and trapping system are directly distant, need to ensure that temperature stabilization in this gas phase pipe is at 180-230 DEG C, therefore increase heat tracing pipe, companion's hot temperature degree of heating tape is 180-230 DEG C, by the boiling temperature of accompanying heat to maintain penta chloropyridine.Expansion joint adopts 316L hose material to make, and flange lap joint flange can be connected with gas phase pipe well.
Described gas phase pipe tilts to install, and the corner that two ends connect is carried out excessively round and smooth, in order to avoid part penta chloropyridine is in corner crystallization, the angle of this gas phase pipe and horizontal direction is 5-15 °.
Described trapping system adopts one-level trap, secondary trap, three-stage trapping device and vavuum pump to be in series, by three-stage trapping device, and the penta chloropyridine powder that can effectively collect sublimates obtains.
Described Blowing stopper is arranged on the bottom of one-level trap, and rotor portion lining PO anticorrosion, junction seals, in order to avoid affect the vacuum state of whole trapping system.
The gas temperature passed through in the pipe of sublimating of described one-level cooling jacket is 120-130 DEG C; For cooling the high temperature penta chloropyridine gas of autoreactor, by regulating the valve at cooling water inlet pipe road and outlet conduit place, the gas temperature that the pipe that ensures to sublimate passes through.
The gas temperature passed through in the pipe of sublimating of described secondary cooling jacket is 90-100 DEG C, cooling is from the cooled device penta chloropyridine gas of sublimating of one-level, outlet conduit due to one-level cooling jacket is connected to the inlet channel of secondary cooling jacket, by regulating keep certain cold and hot ratio to guarantee to sublimate gas temperature that pipe bottom passes through, complete the process of sublimating of penta chloropyridine at this, penta chloropyridine gas becomes powder and enters trapping system.
The utility model is owing to adopting said structure design, and the cooling inflow temperature of one-level cooling jacket is lower, and the inflow temperature of secondary cooling jacket is higher, is the mixing water of outlet warm water with one-level cooling water inlet of one-level cooling jacket.By sublimating in pipe and the steady decline of temperature in one-level cooling jacket and secondary cooling jacket, more easily control de-sublimation temperature, prevent the trap system caking caused because upper temp is too high, also can avoid the blockage of sublimating caused because temperature of lower is too low, improve the quality of products; In addition, owing to being provided with two group reaction devices, significantly can promote operating efficiency, increase production capacity, realize discharging continuous prodution.
