Description
Technical field
The utility model is related to trichloro ethylene technical field, is filled more particularly, to material deacidification in a kind of trichloro ethylene system
Put.
Background technology
Trichloro ethylene production system rectifier unit is in distillation process, and material acidity has the process of enrichment, such as four chloroethenes
Alkane tower top material (low-boiling-point substance) acidity acidity in purification process can be continuously in the degree between 3000-5000pp, for setting
It is standby to require harsh, on subsequent production influence than larger；Because technology upgrading needs production dichloroethylene or other products, if can not remove
Acidity herein is gone, follow-up equipment is required to significantly change, and production cost is higher, so material deacidification is extremely urgent, it is also one
Problem.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide in a kind of trichloro ethylene system
Material deacidification device, to reach the purpose of acid removing in low-boiling-point substance.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used for：
Material deacidification device in the trichloro ethylene system, including blender and subsider, the import of the blender are connected with
Liquid caustic soda pipeline and low-boiling-point substance pipeline, the outlet of blender are connected with the entrance of subsider, upper outlet and the salkali waste pipe of subsider
Road is connected, and the lower part outlet of subsider is connected with material output pipe.
As preferred, the blender is U-shape structure, and the inlet and outlet of blender is in U-shape structure open top end.
As preferred, the inside of the blender is provided with silk screen.
As preferred, the salkali waste pipeline and/or material output pipe are counted provided with PH.
As preferred, provided with the detour structure that arches upward upwards in the material output pipe.
As preferred, the silk screen is one group, is arranged side by side in a mixer along import to Way out.
As preferred, the mesh number of the silk screen is 40-60 mesh.
As preferred, the detour structure that arches upward is inverted U kinking structure.
As preferred, mesh number of the silk screen along import to Way out in the blender increases step by step.
The utility model compared with prior art, with advantages below：
Material deacidification device reasonable in design in the trichloro ethylene system, utilizes acid-base neutralization and low-boiling-point substance and liquid caustic soda
Unmixing principle is deacidified and separated again, and deacidification is efficient, and equipment changes small, and stable and reliable operation, cost is low.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is the utility model material deacidification device structural representation.
In figure：
1. blender, 2. subsiders, 3.PH are counted.
Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation.
As shown in figure 1, material deacidification device in the trichloro ethylene system, including the blender 1 and subsider being arranged side by side
2, the import of blender 1 is connected with liquid caustic soda pipeline and low-boiling-point substance pipeline, and the outlet of blender 1 is connected with the entrance of subsider, sedimentation
The upper outlet of groove 2 is connected with salkali waste pipeline, and the lower part outlet of subsider is connected with material output pipe.
Company between liquid caustic soda pipeline, low-boiling-point substance pipeline, salkali waste pipeline, material output pipe and blender and subsider
Adapter is equipped with magnetic valve on road, and its flow is controlled, and improves deacidification efficiency, and control simplicity.
Blender 1 is U-shape structure, and the inlet and outlet of blender is in U-shape structure open top end, and U-shaped structure is in bottom.
The inside of blender is provided with silk screen, and the mesh number of silk screen preferably is 40-60 mesh.
Silk screen is one group, is arranged side by side in a mixer along import to Way out.Silk screen in blender along import extremely
The mesh number of Way out increases step by step, improves low boiling material and liquid caustic soda mixing contact effect.
Silk screen is stainless steel metal silk screen, material is wherein constantly broken up with liquid caustic soda entrance by silk screen, contact, mixing,
N-process, then into subsider.Mix contact and neutralize deacidification efficiently, reduce cost.
Using low-boiling-point substance and the immiscible principle of liquid caustic soda, into subsider 2 after separate sedimentation, material ratio is great, is sunken to down
Portion, liquid caustic soda proportion is low, on top.
Provided with the detour structure that arches upward upwards in material output pipe.It is preferred that, the detour structure that arches upward is inverted U kinking structure.
Deacidification is efficient, and equipment changes small, and stable and reliable operation, cost is low.Wherein, material outlet is calculated according to the material sedimentation time and exported
The curved height of inverted U.
PH is designed with salkali waste pipeline and material output pipe and counts 3 (pH meters), liquid caustic soda flux is adjusted by acid-base value.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model implement not by
The limitation of aforesaid way, as long as employing the improvement for the various unsubstantialities that design of the present utility model and technical scheme are carried out,
Or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, it is of the present utility model protect
Within the scope of shield.
