Abstract
The utility model discloses a convection sieve plate type rectifying nitrogen column which comprises a tank body and convection sieve plate devices, wherein multi-layer stacked convection sieve plate devices are arranged in the tank body. Due to the adoption of the above technical scheme, CnHm, NO2 and other impurities can not collected on a fin, the plate efficiency is improved, the liquid nitrogen extraction rate is also improved, and harmful impurities, which enter a main cooler, in raw material are reduced.
Description
Technical field
The utility model relates to the plant equipment field, particularly relates to a kind of convection current sieve plate rectifying nitrogen tower.
Background technology
The major product of air separation plant is oxygen and nitrogen.The chemical property torpescence of nitrogen has very big inertia under usual state, be not easy and other material generation chemical reaction.Therefore, nitrogen is used for doing protection gas widely in metallurgical, electron chemistry is industrial.And cryogenic liquid has superiority at storage and transporter mask, so the demand of low temperature liquid nitrogen is more and more, and it is low that the sky branch through routine adds the nitrogen tower recovery rate that uses in the liquefaction process, gathers impurity such as CnHm and NO2 easily at fin.
Summary of the invention
The technical problem that the utility model mainly solves provides a kind of convection current sieve plate rectifying nitrogen tower, can effectively prevent impurity gathering in fin such as CnHm and NO2, improves plate efficiency, improves the nitrogen products recovery rate, reduces the raw material objectionable impurities and gets into main cooler.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of convection current sieve plate rectifying nitrogen tower is provided, and this convection current sieve plate rectifying nitrogen tower comprises tank body and convection current sieve apparatus, is provided with the convection current sieve apparatus of multilayer stack in the said tank body.
Preferably, said convection current sieve apparatus comprises sieve plate, carrying bolt and bracing frame, and support frame as described above is fixed in inner tank wall, and bracing frame is provided with carrying bolt, is installed with a plurality of sieve plates on the carrying bolt, and passes through fixed by nut.
Preferably, lean on the position of convection current sieve apparatus bottom to be provided with liquid dish in the said tank body.
Preferably, said tank body is provided with the liquid in-out mouth.
Preferably, said tank base is provided with the tank body bracing frame.
The beneficial effect of the utility model is: a kind of convection current sieve plate of the utility model rectifying nitrogen tower, can effectively prevent impurity gathering in fin such as CnHm and NO2, and improve plate efficiency, improve the nitrogen products recovery rate, reduce the raw material objectionable impurities and get into main cooler.
