Problems solved by technology

In actual production, there will be agglomeration in the primary and secondary traps. One is that the powder particles cannot be melted again after the block blocks the powder recovery pipeline, resulting in a low recycling rate of the product. The other is that the block It is difficult to clean up after the powder recovery pipeline is blocked, which requires a lot of manpower and material resources, and the production cost increases

Abstract

The invention discloses a pentachloropyridine product catcher block powder separating mechanism. The pentachloropyridine product catcher block powder separating mechanism comprises a catcher body, a primary separator is connected below the catcher body, a secondary separator is connected below the primary separator, the two sides of the secondary separator are connected with a fragment recovery pipeline and a dust recovery pipeline respectively, a butterfly valve is arranged between the catcher body and the primary separator, a primary filter screen is arranged between the primary separator and the secondary separator, a secondary filter screen is arranged on the dust recovery pipeline, a cleaning valve is arranged at the bottom of the secondary separator, a dust cleaning pipeline is connected below the cleaning valve, a stop valve is arranged at the bottom of the dust cleaning pipeline, and the mesh number of the primary filtering screen and the mesh number of the second-stage filtering screen are increased in sequence.

Description

technical field [0001] The invention relates to the field of pentachloropyridine production, in particular to a pentachloropyridine product catcher block powder separation mechanism. Background technique [0002] During the production process of pentachloropyridine, the reaction tail gas and pentachloropyridine sublimation vapor are separated in the primary and secondary traps, and finally the separation is clean. The reaction tail gas is absorbed by the absorption system, and the pentachloropyridine vapor is collected in the primary and secondary traps It is turned into powder particles, recycled to the melting tank for secondary melting through the vacuum system, and finally sliced ​​and packaged. In actual production, there will be agglomeration in the primary and secondary traps. One is that the powder particles cannot be melted again after the agglomerates block the powder recovery pipeline, resulting in a low recycling rate of the product. The other is that the agglome...
