In the present embodiment, pipe main body 410 sidewall can be coated with one layer of heat insulation layer 420 such that it is able to preferably prevents height Heat at temperature medium scatters and disappears through pipe main body 410.The material of heat insulation layer 420 uses aerogel blanket, so that adiabatic Layer 420 is easy to setting and heat insulation effect is preferable.

It addition, the internal diameter of heating flow channel 411 can be 1.5～2 times of feeding-passage 412 internal diameter, so that add hot-fluid Raw material in feeding-passage 412 can relatively quickly be preheated by the high-temperature medium in road 411, so that logical in charging When raw material flow rate in road 412 is very fast, the high-temperature medium in heating flow channel 411 also is able to preferably in feeding-passage 412 Raw material preheats.

In the present embodiment, the inwall of heating flow channel 411 and feeding-passage 412 all can be provided with one layer of corrosion-inhibiting coating, thus Can preferably avoid the corrosion that heating flow channel 411 or feeding-passage 412 are caused by high-temperature medium or raw material.

In the present embodiment, at the housing of all conveyance conduits 1203, it is equipped with intermediate layer of water-flowing, heating flow channel 411, water service pipe 120 and all conveyance conduits 1203 at intermediate layer of water-flowing be sequentially connected with, and heating flow channel 411, water service pipe 120 and all water flowings folder It is provided with, in Ceng, the aqueous water circulated by circulating pump.

In the present embodiment, in heating flow channel 411, water service pipe 120 and all intermediate layer of water-flowings, it is provided with recycle stream by circulating pump Dynamic aqueous water such that it is able to preferably the heat at all conveyance conduits 1203 is reclaimed for former to plastics-production Material carries out heating or being incubated, and then preferably achieves the recycling of heat.

In the present embodiment, it is equipped with waste gas at batch mixer the 4, first cyclone separator 8 and the second cyclone separator 9 and discharges Mouthful, all waste gases outlet is all connected with a spray column.

In the present embodiment, the waste gas discharged at batch mixer the 4, first cyclone separator 8 and the second cyclone separator 9, it is possible to Process preferably by spray column such that it is able to effectively waste gas is processed.

Schematically being described this utility model and embodiment thereof above, this description does not has restricted, accompanying drawing Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So, if this area Those of ordinary skill enlightened by it, creating in the case of objective without departing from this utility model, designing without creative The frame mode similar to this technical scheme and embodiment, all should belong to protection domain of the present utility model.
