Abstract
The utility model relates to an unloading in -process is used for the device of wash line after the adipic acid thickening, specifically is a pipeline washing unit. A pipeline washing unit, includes that its internal fixation has the pipeline of bracing ring, the bracing ring is fixed with annular shower nozzle in the pipeline, is connected with supplementary flushing line on the annular shower nozzle. This pipeline washing unit installs on thick sour thickener gets into the pipeline of the jar of sizing mixing, and supplementary flushing line connects cold mother liquor house steward. During the use, open the valve that cold mother liquor house steward got into pipeline washing unit, annular shower nozzle flowed out during pipeline washing unit was followed to cold mother liquor, and constantly flush pipe way inner wall guarantees that the unloading of adipic acid material is smooth and easy, prevents the jam. The utility model discloses thoroughly improve easily stifled pipeline and handled the trouble for adipic acid production, reduced intensity of labour, improved the equipment operation equipment -hour, gained better economic benefits.
Description
Technical field
The utility model relates to the device for detergent line in blanking process after adipic acid thickening, is specially a kind of pipeline flushing device.
Background technology
In adipic acid production process, the adipic acid that reaction produces is through crystallization, thickening, and adipic acid material concentration gets a promotion, and because a large amount of nitric acid in mother liquor are extracted reuse by enrichment process, the solubility of the adipic acid slurry of 40wt% reduces greatly.After adipic acid material flows out from thick acid-thickened device feed opening, be very easily attached to tube wall causes scab, line clogging.
Summary of the invention
The utility model, in order to solve the problem of easy blocking pipe in adipic acid material blanking process, provides a kind of pipeline flushing device.
The utility model adopts following technical scheme to realize: a kind of pipeline flushing device, comprise the pipeline that its internal fixtion has bracing ring, pipe inside support ring is fixed with annular nozzle, annular nozzle is connected with auxiliary clean-up line.
This pipeline flushing device is arranged on thick acid-thickened device and enters and size mixing on the pipeline of tank, and auxiliary clean-up line connects cold mother liquor house steward.During use, open cold mother liquor house steward enters the valve of pipeline flushing device, and cold mother liquor annular nozzle from pipeline flushing device flows out, and constantly washes away inner-walls of duct, ensures that the blanking of adipic acid material is smooth and easy, prevents blocking.
The utility model thoroughly improves the trouble that easy blocked pipeline process is produced to adipic acid, reduces labour intensity, when the equipment that improves runs platform, achieves good economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-pipeline, 2-bracing ring, 3-annular nozzle, 4-assists clean-up line.
Detailed description of the invention
A kind of pipeline flushing device, comprise the pipeline 1 that its internal fixtion has bracing ring 2, pipe inside support ring 2 is fixed with annular nozzle 3, annular nozzle 3 is connected with auxiliary clean-up line 4.
During concrete enforcement, pipeline 1 adopts DN250, material is S30403, built-in annular nozzle 3 ring footpath is DN200, auxiliary clean-up line 4 diameter is 21 × 4, and annular nozzle 3 is a ring body, and ring body evenly has flushing hole, flushing hole spacing 39mm, flushing hole to be oriented along inner-walls of duct horizontal direction downward 30 °.
Claims (1)
1. a pipeline flushing device, it is characterized in that comprising the pipeline (1) that its internal fixtion has bracing ring (2), pipe inside support ring (2) is fixed with annular nozzle (3), annular nozzle (3) is connected with auxiliary clean-up line (4).
