Description
Technical field
The utility model relates to Chemical Industry Drying equipment, is specifically related to a kind of monochloro methane drying equipment.
Background technology
Monochloro methane is important industrial chemicals, and because of its explained hereafter characteristic, hydrogen chloride is one of byproduct, can produce acid after being combined with water, will produce corrosion.But corrosion not only can cause equipment and process Pipeline damage, serious also can cause parking, causes material from leakage to cause environmental pollution, even occurs security incident.So corrode the natural enemy that methane chloride production device is maximum just.
Therefore the moisture how removed in monochloro methane gas phase becomes the problem needing solution badly.
Utility model content
For there being the defect of technology on overcoming, the purpose of this utility model is intended to propose a kind of monochloro methane drying equipment.
For achieving the above object, the utility model adopts following technical scheme:
A kind of monochloro methane drying equipment, comprises Quench groove, acid condenser, product separator, demister, sulfuric acid tower, monochloro methane compressor; It is characterized in that: the air inlet of described Quench groove is connected with monochloro methane gas phase appendix by pipeline, the gas outlet of Quench groove is connected to the air inlet of acid condenser by pipeline; The gas outlet of described acid condenser is connected to the air inlet of product separator by pipeline; The gas outlet of described product separator is connected to the air inlet of demister by pipeline; Described sulfuric acid tower comprises the dry tower of sulfuric acid and dry two towers of sulfuric acid; The gas outlet of described demister is connected to by pipeline the air inlet that the dry tower of sulfuric acid is positioned at side bottom; The gas outlet that the dry tower of described sulfuric acid is positioned at top, another side is connected to by pipeline the air inlet that dry two towers of sulfuric acid are positioned at side bottom; The gas outlet that dry two towers of described sulfuric acid are positioned at top, another side is connected to the air inlet of monochloro methane compressor by pipeline.
Explanation and the further scheme of such scheme are as follows:
1, in such scheme, the number of described acid condenser is two; The liquid outlet of described acid condenser is connected to the inlet of Quench groove by pipeline.
2, in such scheme, the top of the dry tower of described sulfuric acid and dry two towers of sulfuric acid is provided with fluid level control valve.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is fully dry to the moisture in monochloro methane gas phase, greatly reduces acidic possibility.Further reduce stop frequency, decrease maintenance cost, reduce the probability that security incident occurs, create good economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of most preferred embodiment of the present utility model.
In above accompanying drawing: 1, Quench groove; 2, acid condenser; 3, product separator; 4, demister; 5, sulfuric acid tower; 51, the dry tower of sulfuric acid; 52, dry two towers of sulfuric acid; 6, monochloro methane compressor; 7, monochloro methane gas phase appendix; 8, fluid level control valve.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 1:
A kind of monochloro methane drying equipment, comprises Quench groove 1, acid condenser 2, product separator 3, demister 4, sulfuric acid tower 5, monochloro methane compressor 6; The air inlet of described Quench groove 1 is connected with monochloro methane gas phase appendix 7 by pipeline, and the gas outlet of Quench groove 1 is connected to the air inlet of acid condenser 2 by pipeline; The gas outlet of described acid condenser 2 is connected to the air inlet of product separator 3 by pipeline; The gas outlet of described product separator 3 is connected to the air inlet of demister 4 by pipeline; Described sulfuric acid tower 5 comprises the dry tower 51 of sulfuric acid and dry two towers 52 of sulfuric acid; The gas outlet of described demister 4 is connected to by pipeline the air inlet that the dry tower 51 of sulfuric acid is positioned at side bottom; The gas outlet that the dry tower 51 of described sulfuric acid is positioned at top, another side is connected to by pipeline the air inlet that dry two towers 52 of sulfuric acid are positioned at side bottom; The gas outlet that dry two towers 52 of described sulfuric acid are positioned at top, another side is connected to the air inlet of monochloro methane compressor 6 by pipeline; The number of described acid condenser 2 is two; The liquid outlet of described acid condenser 2 is connected to the inlet of Quench groove 1 by pipeline; The top of the dry tower 51 of described sulfuric acid and dry two towers 52 of sulfuric acid is provided with fluid level control valve 8.
Reacted gas phase wets monochloro methane through Quench groove 1 Quench, then by entering reactor product separator 3 after two acid condenser 2 circulating water condensing coolings.Condensate liquid turns back to Quench groove 1 by gravity and makes Quench liquid, and humid gas, after demister 4 foam removal drainage, enters the dry tower 51 of sulfuric acid from bottom, its top out after, enter bottom dry two towers 52 of sulfuric acid again, top out after, a small amount of water, methyl alcohol and the dimethyl ether that contain in removing monochloro methane.Dry monochloro methane leaves sulfuric acid tower 5 and enters monochloro methane compressor 6 and compress.
In the dry tower 51 of sulfuric acid, concentrated sulfuric acid concentration controls at 95-97%, and in dry two towers 52 of sulfuric acid, concentrated sulfuric acid concentration controls 85%, and the concentrated sulfuric acid is sent under fluid level control valve 8 automatic control regulates.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
