Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing.
[0021] like figure 1 As shown, the desublimation device 100 includes a desublimation cylinder 110 provided with an air inlet 112 and an air outlet 113 , a cooling jacket 120 disposed on the desublimation cylinder 110 , and a rotating shaft disposed in the desublimation cylinder 110 130, and the distributor 140 arranged on the rotating shaft 130; the desublimation cylinder 110 is also provided with a material outlet 114. Wherein, the air inlet 112 and the gas outlet 113 are usually arranged at opposite ends of the desublimation cylinder 110, so that the high freezing point substances in the gas are fully condensed in the desublimation cylinder 110; the material outlet 114 ( figure 1 not shown, see figure 2 ) is usually arranged on the lower side of the desublimation cylinder 110 to facilitate the discharge of solid high freezing point substances from the desublimation cyl...

The invention belong to the technical field of gas treatment, particularly discloses a desublimation device and a tail gas treatment system, and aims at solving the problems that a current desublimation device cannot operate continuously and the desublimation efficiency is low. The desublimation device comprises a desublimation canister body provided with a gas inlet and a gas outlet, a cooling clamp cover arranged on the desublimation canister body, a rotary shaft arranged in the desublimation canister body and a distributing device arranged on the rotary shaft; the desublimation canister body is further provided with a material outlet. The tail gas treatment system comprises the desublimation device. High-desublimation-point material gas entering the desublimation canister body can be sublimated through the cooling clamp cover arranged on the desublimation canister body, the material sublimated on the inner wall of the desublimation canister body is distributed through the distributing device installed on the rotary shaft to form a material curtain, and the desublimation efficiency is high; finally, the solid high-desublimation-point material gas is discharged from a material outlet, accordingly the situation of overmuch gathered solid high-desublimation-point material gas is avoided, and the continuous operation of desublimation is achieved.
Description
technical field [0001] The invention belongs to the technical field of gas treatment, and in particular relates to a desublimation device and a tail gas treatment system. Background technique [0002] Sublimation-prone substances are often separated and captured by desublimation devices, but the existing desublimation devices often have the problems of inability to operate continuously and low desublimation efficiency, especially when the gas contains less desublimation substances , the sublimation effect is often unsatisfactory. [0003] For example, when 2,6-dichloropyridine and pentachloropyridine are produced by pyridine chlorination, the tail gas often contains some chloropyridine gas with high freezing point. During the conventional tail gas treatment process, this part of the high freezing point substance will condense in the pipeline. Or in the tail gas absorption tower, not only is it not conducive to the capture of these high freezing point substances, but also it...
