Description
Technical Field
The utility model relates to an ethylene glycol production field, concretely relates to pipeline gas-liquid mixing device of production coal system ethylene glycol.
Background
In the production of ethylene glycol from coal, it is usually necessary to uniformly distribute the oxalate in the hydrogen so that the reaction can proceed smoothly. In order to solve the problem that the oxalate liquid and hydrogen are uniformly mixed and distributed, Chinese patent CN201320305420.1 discloses a simple device for pipeline gas-liquid mixing of coal-to-ethylene glycol, which solves the problem that the oxalate liquid and hydrogen are uniformly mixed and distributed, but for a main hydrogen pipeline with large pipe diameter and large flow rate, the phenomenon of scaling and blockage caused by nonuniform mixing and distribution still exists, and the elbow of an oxalate liquid inlet pipe is seriously worn and has a long service life after being washed by a medium for a long time.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model provides a pipeline gas-liquid mixing device for producing coal-to-ethylene glycol.
The utility model discloses a realize through following technical scheme:
the utility model provides a pipeline gas-liquid mixing device of production coal system ethylene glycol, includes the hydrogen trunk line, the outer wall intercommunication of hydrogen trunk line is fixed with oxalate feed liquor pipe, oxalate feed liquor pipe one end extends to inside and fixed with the spiral spray tube intercommunication of setting in the hydrogen trunk line of hydrogen trunk line, it has a plurality of orifice to open the inboard outside on the inner wall of spiral spray tube, the lower extreme passes through the connecting plate on the spiral spray tube and fixes with hydrogen trunk line inner wall, the elbow junction front end adoption arc wedge setting of oxalate feed liquor pipe and spiral spray tube.
Preferably, the outer wall of the hydrogen main pipeline is provided with an overhaul manhole opposite to the spiral spray pipe, and the outer side of the oxalate liquid inlet pipe is fixed with the outer wall of the hydrogen main pipeline through a reinforcing rib.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up the spiral spray tube that has interior outer orifice in hydrogen trunk line, oxalate carries out whole atomizing at hydrogen trunk line inner tube local area spiral injection, simultaneously mix with the high-temperature hydrogen of high-speed flow, the injection region of oxalate has wholly been improved like this, the interfacial area when having enlarged the oxalate of vaporization and hydrogen mix, mixing rate strengthens greatly, the effectual homogeneity that has guaranteed the hydrogen of big pipe diameter high flow and oxalate mixture, it splits the point to set the arc with oxalate feed liquor pipe and spiral spray tube connection elbow department, reduce and the high-speed hydrogen resistance that flows, the friction to elbow department has been reduced, the effective life-span that has increased oxalate feed liquor pipe elbow.
