Abstract
The utility model discloses a security device for preventing harmful gas leakage in 2-nitryl-4-trifluoromethyl cyanophenyl production. The device comprises a reaction kettle, a packing absorbing tower, a cooler and an absorbing liquid storage tank, wherein the reaction kettle is connected with the packing absorbing tower through a waste gas pipeline; the cooler is positioned at the lower part of the packing absorbing tower; a view lens is arranged on a pipeline for connecting the cooler and the absorbing liquid storage tank; the absorbing liquid storage tank is connected with an inlet of an absorbing ejection pump; two branch pipelines are arranged at the outlet of the absorbing ejection pump; one branch pipeline is connected to the top end of the packing absorbing tower; the other branch pipeline is connected with a Venturi tube and is connected to the top end of the absorbing liquid storage tank; a gas pipeline is connected to the bottom of the cooler and is connected with an inlet of the Venturi tube. The device adopts the Venturi principle to change the pressure of the system, the reaction kettle is kept in negative pressure, toxic and harmful gases can be directly fed into the packing absorbing tower from the reaction kettle after being generated, and are absorbed by a sprayed circulation absorbing liquid, and thus the gases are not retained inside the reaction kettle or are not directly discharged into the atmosphere.
Description
Technical field

Detailed description of the invention
As accompanying drawing 1, a kind of safety device that prevents poisonous gas leakage of producing for 2-nitro-4-trifluoromethyl Benzonitrile, comprises reactor, packed absorber, cooler and absorption liquid storage tank; Reactor is connected by exhaust piping with packed absorber, cooler is positioned at the bottom of packed absorber, the pipeline connecting between cooler and absorption liquid storage tank is provided with visor, absorption liquid storage tank connects the entrance that absorbs jet pump, absorb injection delivery side of pump and have two laterals, a lateral is connected to the top of packed absorber, another lateral connects Venturi tube and is connected with the top of absorption liquid storage tank, and cooler bottom connects a gas pipeline and is connected with the porch of Venturi tube.
Cooler is provided with recirculated water reflux.
Described recirculated water reflux comprises: recirculated water water supply pipeline is installed in cooler lower end, and recirculated water water return pipeline is installed in cooler upper end.
On absorption liquid storage tank, be also provided with running water water inlet pipe.
On two laterals of absorption jet pump outlet, be all provided with valve.
Absorption liquid is transported to Venturi tube from absorption liquid storage tank by absorbing jet pump part, absorption liquid forms vacuum in Venturi tube makes gas pipeline, cooler, packed absorber and reactor, when toxic and harmful produces, under pressure differential effect, this waste gas can enter packed absorber from reactor and neither can remain in and in reactor, also can directly not enter air.Meanwhile, another part absorption liquid is transported to packed absorber and sprays, and waste gas fully contacts after complete reaction with absorption liquid in packed absorber, and absorption liquid is got back to absorption liquid storage tank through cooler, visor.Its mesoscope can observe absorption liquid flow, thereby valve can be controlled air pressure and the absorption liquid spray flux of the absorption liquid flow control device inside of two branch roads.This device can ensure toxic and harmful to absorb, ensure safety of workers and protection of the environment completely.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
