Utility model content
Technical problem to be solved in the utility model is to provide the emergency system in the preparation of a kind of difluoromethane, with the leakage preventing fluorination reactor from causing after being corroded, eliminates or at utmost reduces the impact on environment.
For solving above technical problem, emergency system in difluoromethane described in the utility model preparation, including the fluorination reactor of the feed pipe of band inlet valve, fluorination reactor is connected to concentration tower by discharge nozzle, and this fluorination reactor connects accident emergency tank by the emergent pipe of band emergency valve.
Further, described accident emergency tank being additionally provided with the loop pipe of tape loop valve, this loop pipe is connected on the discharge nozzle of fluorination reactor.
Further, described discharge nozzle being provided with outlet valve, described loop pipe is connected between outlet valve and concentration tower, and the fluorination reaction product come in accident emergency tank enters concentration tower by this pipeline and processes, and increases the utilization rate of material.
Further, being provided with return duct bottom described concentration tower, this return duct is connected to the side on fluorination reactor top.
Further, the periphery of described fluorination reactor is provided with chuck, and the top of this chuck connects the steam inlet duct having carrying vapour valve, and chuck bottom is provided with steam outleting pipe.
Further, what described accident emergency tank was additionally provided with exhaust valve of taking goes offgas duct, and this goes offgas duct to be connected to device for absorbing tail gas.
Further, the open and close of described fluorination reactor and the pressure of accident emergency retort and inlet valve, outlet valve, emergency valve, steam valve, reflux inlet and return valve are all controlled by Computerized monitor system, control of can making a response rapidly is reacted, and avoids the generation of accident further.
This utility model, by setting up accident emergency tank, connects fluorination reactor, when making fluorination reactor cause leakage because being corroded, can be caused by the gas revealed in this accident emergency tank, it is to avoid leakage thing pollution on the environment.The most also by the discharge nozzle of accident emergency tank connection fluorination reactor, the product of leakage is made to be fully utilized.Whole system is controlled by computerized control system, not only controls the most in real time, and the personnel that need not put in place, and staff plays insulation blocking effect.

Detailed description of the invention
Embodiment of the present utility model:
As shown in Figure 1, emergency system in difluoromethane of the present utility model preparation, including fluorination reactor 1, this fluorination reactor 1 is coated with chuck 11, logical steam in chuck 11, steam enters from the steam inlet duct 15 being positioned at chuck 11 top, gives vent to anger from the steam outleting pipe 15 ' being positioned at chuck 11 bottom, steam inlet duct 15 is provided with steam valve 151.The top of fluorination reactor 1 is provided with the material feeding tube 12 being always passed through bottom fluorination reactor 1, and feed pipe 12 is provided with inlet valve 121.The discharge nozzle 13 of band outlet valve 131 it is additionally provided with at fluorination reactor 1 top, discharge nozzle 13 is passed through the bottom of concentration tower 3, products therefrom is carried out subsequent treatment, being additionally provided with the return duct 16 of band reflux inlet 161 bottom concentration tower 3, the other end of this return duct 16 is connected to fluorination reactor 1 upper lateral part.The emergent pipe 14 of a band emergency valve 141 it is also associated with from the top of fluorination reactor 1, this emergent pipe 14 is connected to accident emergency tank 2, this accident emergency tank 2 is additionally provided with the loop pipe 21 of a tape loop valve 211, loop pipe 21 is connected on the discharge nozzle 13 of fluorination reactor 1, and junction is between outlet valve 131 and concentration tower 3.Be additionally provided with exhaust valve 221 of taking on accident emergency tank 2 goes offgas duct 22, and this goes offgas duct 22 to be connected to device for absorbing tail gas.
For the pressure in monitoring of containers, it is ensured that safety, fluorination reactor 1 and accident emergency tank 2 are provided with Pressure gauge.The Pressure gauge of fluorination reactor 1 and accident emergency tank 2 and inlet valve 121, outlet valve 131, reflux inlet 161, emergency valve 141, return valve 211 all connect Computerized monitor system with steam valve 151.
In course of reaction, when fluorination reactor 1 is corroded generation leakage, Computerized monitor system i.e. monitors and learns, immediately pass through Computerized monitor system and close inlet valve 121, reflux inlet 161 and outlet valve 131, block charging and discharging, steam off valve 151, stop heating, and open emergency valve 141 and return valve 211, owing to the pressure in fluorination reactor 1 is about 1.5MPa, pressure in accident emergency tank 2 is then far smaller than this value, therefore the material in fluorination reactor 1 can be made to enter smoothly in accident emergency tank 2 through emergent pipe 14, fluorination reactor 1 rapid pressure drop.Material in accident emergency tank 2 then can be entered in concentration tower 3 by loop pipe 21 further, makes full use of.After accident treatment completes, the residual material in accident emergency tank 2 will remove exhaust valve 221 by unlatching, go device for absorbing tail gas to process through going offgas duct 22 to enter.
