Abstract
The utility model discloses a nitrogen gas replacement protection device comprises reation kettle, agitator, unload pipeline and outlet duct, is that the intake pipe communicates with each other on the discharge tube line and with the discharge tube on -line through flange mounting, is equipped with gas flowmeter, ball valve, needle type valve, manometer and check valve by the air inlet in proper order to the gas outlet orientation in the intake pipe, and the outlet duct is installed at the reation kettle top, the utility model has the characteristics of make before the chemical industry reaction with reaction sequence in the air replacement more thoroughly, safe and reliable, reach anhydrous anaerobic and isolated air reaction condition, improve the productivity of reaction.
Description
Technical field
The utility model belongs to fine chemistry industry and prohibits water, prohibits oxygen, completely cuts off air reaction still equipment technical field, especially relates to a kind of reaction kettle nitrogen replacement protective device.
Technical background
Fine chemistry industry usually needs to pass into nitrogen before starting the reaction in producing and carrys out displaced air, reach the reaction condition of anhydrous and oxygen-free and isolated air, require in course of reaction that the reaction of anhydrous and oxygen-free and isolated air also needs to pass into nitrogen in the process of reaction, to maintain the reaction condition of anhydrous and oxygen-free and isolated air, the nitrogen displacement that reactor is used in Fine Chemical at present and protective device, generally can adopt bottom nitrogen tube being passed into reactor from the top cover of reactor, the mode of top discharge, but there is agitator in reactor, and often can not lead to bottommost, sizable space bottom reactor is caused to be difficult to effective displacement.Air displacement in reactor does not thoroughly not only reach the condition of anhydrous and oxygen-free and isolated air, and reaction is affected, and productive rate declines, if run into inflammable and explosive reaction mass also there is serious potential safety hazard.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of and make before chemical reaction and air displacement in course of reaction is more thorough, safe and reliable, the reaction condition that reaches anhydrous and oxygen-free and isolated air, the nitrogen displacement protective device of productive rate that improves reaction.
The purpose of this utility model realizes like this; a kind of nitrogen displacement protective device; be made up of reactor, agitator, discharging pipeline and escape pipe; be characterized in that air inlet pipe to be arranged on discharging pipeline by flange and to communicate with in discharging pipeline; air inlet pipe is provided with gas flowmeter, ball valve, needle valve, Pressure gauge and check (non-return) valve by air inlet successively to direction, gas outlet, and escape pipe is arranged on reactor top.
In order to realize the purpose of this utility model further, can be that Open Side Down for the gas outlet of air inlet pipe.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts nitrogen to pass in the bottom of reactor, top discharge is to emission-control equipment, nitrogen passes into pipeline and to be arranged on bottom reactor on discharging pipeline, nitrogen passes on pipeline and installs check (non-return) valve, Pressure gauge, needle valve, ball valve and gas flowmeter, Pressure gauge and gas flowmeter are by detecting pressure and the flow of nitrogen conveying, whether normal in order to judge nitrogen conveying, check (non-return) valve can prevent material from entering nitrogen inlet pipeline blocking pipeline, needle valve and ball valve effectively can control the inlet of nitrogen, ensure enough nitrogen supply (NS) amounts, Open Side Down in the gas outlet of air inlet pipe, enters nitrogen inlet pipeline to avoid material, the utility model is compared with existing apparatus, and displaced air is more thorough, and safety coefficient is higher, before feeding intake, lead to nitrogen displaced air to whole reactor, the contact of reaction mass and air can be avoided, effectively prevent the generation of blast and fire, eliminate potential safety hazard, prohibit oxygen reaction and carry out, in process, bottom reactor, passing into nitrogen, can thorough displaced air, effectively avoid reactant to contact with air, reach the reaction condition of anaerobic, improve the productive rate of reaction.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further details.
A kind of nitrogen displacement protective device; with reference to Fig. 1;, in reactor 2, agitator 1 is installed; the discharging pipeline 3 being provided with valve 4 is arranged on bottom reactor 2; escape pipe 5 is arranged on reactor top; air inlet pipe 11 to be arranged on above the valve 4 of discharging pipeline 3 by flange 7 and to communicate with in discharging pipeline 3, and air inlet pipe 11 is provided with gas flowmeter 10, ball valve 9, needle valve 12, Pressure gauge 6 and check (non-return) valve 8 by air inlet successively to direction, gas outlet.
In order to avoid material enters in nitrogen inlet duct 11, with reference to Fig. 2, Open Side Down in the gas outlet of air inlet pipe 11.
