Description
Technical field
This utility model is related to a kind of cold doubtful device, and particularly a kind of high pressure condenser for being applied to fluorination reaction is main to use
In fluorination reaction of the picoline quasi-aromatic compound under the pressure of more than 3.0Mpa.
Background technology
Currently used for fluorination reaction high pressure condenser more than exchanged heat using shell and tube, including housing, the upper end of housing according to
It is secondary to be connected with upper perforated plate, upper cover, lower perforated plate, low head is connected with turn in the lower end of housing, between upper perforated plate and lower perforated plate
It is connected with a branch of heat exchanger tube, upper cover is provided with mouth under tube side, upper cover is provided with that tube side is suitable for reading, and mouth is suitable for reading with tube side under tube side
By the inner chamber of low head, heat exchanger tube, upper cover intracavity inter-connection, housing side bottom is provided with mouth under shell side, the side of housing
Face top is provided with that shell side is suitable for reading, mouth and the shell side intracavity inter-connection by housing suitable for reading under shell side.The condenser of this structure exists
In high pressure fluorination reaction, the effect for trapping fluohydric acid gas is poor, and fluohydric acid gas consumption is larger, consumes many beyond reaction.
The content of the invention
The purpose of this utility model be to provide a kind of simple structure, trapping fluohydric acid gas effect it is good, fluorination hydrogen loss it is few, reduce
The high pressure condenser for being applied to fluorination reaction of production cost, overcomes the deficiencies in the prior art.
The high pressure condenser for being applied to fluorination reaction of the present utility model, including housing, is sequentially connected in the upper end of housing
There are upper perforated plate, upper cover, lower perforated plate, low head is connected with turn in the lower end of housing, is connected between upper perforated plate and lower perforated plate
A branch of heat exchanger tube, low head are provided with mouth under tube side, and upper cover is provided with that tube side is suitable for reading, and under tube side, mouth is suitable for reading by under with tube side
The inner chamber of end socket, heat exchanger tube, the intracavity inter-connection of upper cover, housing side bottom are provided with mouth under shell side, the side surface upper part of housing
It is provided with that shell side is suitable for reading, mouth and the shell side intracavity inter-connection by housing suitable for reading under shell side；The inner chamber of described low head is provided with down
Sieve plate, lower sieve plate are located at below described lower perforated plate, pile up the Raschig ring filler for having nickel material in each heat exchanger tube.
Described lower sieve plate is supported by lower supporting plate, is welded and fixed between lower supporting plate and low head；In upper cover
Chamber is provided with upper sieve plate, and upper sieve plate is supported by upper backup pad, is welded and fixed between upper backup pad and upper cover.
The high pressure condenser for being applied to fluorination reaction of the present utility model, compared with prior art, due in heat exchanger tube
The Raschig ring filler of nickel material is distributed with, overcomes that condenser arresting efficiency under the conditions of high pressure fluorination reaction is high, fluorination hydrogen loss
The drawbacks of losing excessive, reduces production cost.
Description of the drawings
Fig. 1 is the structural representation of this utility model specific embodiment.
Specific embodiment
As shown in Figure 1：8 is cylinder shell, the upper end of housing 8 be connected with turn by bolt upper perforated plate 10, on seal
11.Lower perforated plate 5, low head 4 are connected with turn by bolt in the lower end of housing 8.Connect between upper perforated plate 10 and lower perforated plate 5
There are a branch of many parallel heat exchanger tubes 6.Low head 4 is provided with mouth 1 under tube side, and upper cover 11 is provided with tube side suitable for reading 12, tube side
Lower mouth 1 is with tube side suitable for reading 12 by the inner chamber of low head 4, heat exchanger tube 6, the intracavity inter-connection of upper cover 11.8 side lower of housing
Mouth 7 under shell side are provided with, the side surface upper part of housing 8 is provided with shell side suitable for reading 9, mouth 7 suitable for reading with shell side 9 is by the interior of housing 8 under shell side
Chamber is connected.
The inner chamber of low head 4 is provided with lower sieve plate 3, and lower sieve plate 3 is located at below lower perforated plate 5, piles up in each heat exchanger tube 6
There is the Raschig ring filler of nickel material.
Lower sieve plate 3 is supported by lower supporting plate 2, is welded and fixed between lower supporting plate 2 and low head 4.In upper cover 11
Chamber is provided with upper sieve plate 13, and upper sieve plate 13 is supported by upper backup pad 14, is welded and fixed between upper backup pad 14 and upper cover 11.
As the Raschig ring filler of nickel material is distributed with heat exchanger tube 6, lower section is stopped by lower sieve plate 5, to prevent nickel
The Raschig ring filler of material falls.During operation, filled with the Raschig ring filler of nickel material by the fluorination hydrogen fluid of 6 inner chamber of heat exchanger tube
Tap is touched, and is increased the fluohydric acid gas of condensation and the contact area of uncooled hydrogen fluoride gas, is dropped low gas velocity, so as to increase heat exchange effect
Rate, the effect for strengthening trapping fluohydric acid gas.Overcome that condenser arresting efficiency under the conditions of high pressure fluorination reaction is high, fluorination hydrogen loss
Excessive the drawbacks of, reduce production cost.
