Problems solved by technology
Resulting in low overall coagulation efficiency and frequent switching operations
At the same time, it is necessary to switch between hot and cold media. The repeated hot and cold impact on the equipment material will easily cause temperature difference stress on the equipment and cause equipment fatigue.
[0003] Some gaseous materials are prone to self-polymerization or thermal decomposition reactions in the process of heating and melting after condensation and capture, resulting in material loss and pollution
After this kind of material is condensed, it is usually necessary to open the condensing equipment and wash it down with a high-pressure water gun or collect it by other physical means. The operating conditions on site are harsh and difficult.

The invention discloses a continuous desublimation and crystallization machine. The continuous desublimation and crystallization machine is an efficient gas material collection device and comprises a box body and a finned-tube bundle group in the box body. A gas material is congealed on finned-tube bundles in the box body, the rotating finned-tube bundles separate the congealed solid material from fins in a scraping mode through the scraper effect of comb-like scraper blades, the material is stacked in a bottom storage space of the box body under the action of gravity, and the bottom storage space conveys the solid material to a loading and unloading port through a screw conveying device. By means of the machine, continuous operation of the desublimation, crystallization and collection processes is achieved, the desublimation and crystallization efficiency is improved, and the heat exchange area is saved.
Description
technical field [0001] The invention relates to a continuous sublimation crystallizer, in particular to a highly efficient gas material collection device. Background technique [0002] At present, in many chemical productions, the collection equipment of gaseous materials is still quite backward, and it still stays in the state of intermittent condensation collection and then heating and melting collection. During the collection process, the gaseous material is mostly used to gradually condense into solids on the surface of the finned condenser tube. With the increase of the condensed material, the condensation heat transfer coefficient decreases, and the condensation effect gradually deteriorates. When the condensed material cannot be condensed, the condensation is suspended and the heat source is switched to melt the material. Carry out discharging, after completing the discharging, switch the refrigerant to collect the material desublimation, and so on. As a result, the ...
